TF700 Battery Drain problem w/dock - Controlled Testing Thread - Asus Transformer TF700

The purpose of this thread is do some controlled testing with the TF700/Dock combination in order to try and identify the battery drain that many users have been experiencing while their tablet is docked. A select group of users have volunteered to participate in these controlled tests. Of course, anyone is free to join in on the testing, but please note that you will NOT be able to use the TF700 while testing (which could take all weekend) and that *ALL* data will need to be wiped in order to participate in the testing!
General Notes:
- In order to do this testing, we **WILL** be wiping **ALL** data on the device. If you want to be able to restore to your original configuration when the testing is complete, please make sure that you have a full nandroid backup!!
- Please record the versions of everything before starting the test. A list of what "everything" includes is listed below. Also, please make sure that you are at the versions specified for each test "scenario" before testing - this is critically important!
- You will need to leave your TF700 docked and completely "unused" during the tests - please don't "cheat" so that we can keep the tests valid!
- As hard as it may be to resist, please don't change *ANY* settings from the recommended settings for each test scenario! A change that seems completely innocent may just end up being the culprit! We need all testers to keep all settings the EXACTLY the same, or else this testing won't be successful!
So far we have (6) testers - (3) that have the drain problem and (3) that do not, which actually works out perfect! Here are the (6) "official" testers:
- fsured (does have the drain problem)
- Dock: DOCK-EC21N-0105
- Tablet: PAD-EC20T-0216
- Drenus (does NOT have the drain problem)
- Dock: DOCK-EC20N-0207
- Tablet: PAD-EC20T-0216
- berndblb (does NOT have the drain problem)
- Dock: DOCK-EC21N-0105
- Tablet: PAD-EC20T-0216
- workdowg (does have the drain problem)
- Dock: DOCK-EC21N-0105
- Tablet: PAD-EC20T-0216
- ntunix (does have the drain problem)
- Dock: ??????
- Tablet: ??????
- jtrosky (does NOT have the drain problem)
- Dock: DOCK-EC20N-0207
- Tablet: PAD-EC20T-0216
I will reserve the following (5) posts in this thread - one for each of the controlled test scenarios. Hopefully, we'll determine something in five tests...
I will post the first scenario ASAP - although, I may have a delay with the first one as I need to unexpectedly go and meet my parents today for "brunch"! I'll try to get it ready before I leave, but I don't want to make any promises.
Like I said, even if you are not an "official" tester, please feel free to test along with us!
Before we do anything, can each of the (6) official testers please PM me with the following version info:
- Bootloader Version (including US/WW values)
- CROMi-X Version (including US/WW and DEODEX/ODEX values)
- Kernel type and version
- PAD Version (from Settings->About)
- MobileDock Version (from Settngs->About)

Thank you for your assistance!!!

Test Scenario 2
Basically, just keep the configuration from test 1, but added a Google account, let sync and then let sleep for another (4) hours.
Please record before/after battery levels.
Change Details
- Plug device back into power while doing this
- Add a Google account:
- Settings -> Add account
- Select "Google" and "Existing"
- Add account info and leave "Keep me up to date with news and offers from Google Play" checked
- Leave "Keep this tablet backed up with my Google Account"
At this point, go into Settings -> Google account and monitor it while it syncs everything up.
After everything is done syncing and all Play apps have been updated (4 apps automatically updated in my case), go back to the home screen and let's let it sleep for another (4) hours and see if that changes anything (don't forget to disconnect the power cable again!!)
Thank you!

Test scenario 3
Simply undock and redock the tablet and let it sit overnight!

Test scenario 4
1. Install "Battery Drainer" app from Play Store (https://play.google.com/store/apps/details?id=com.batterydrainer)
2. Run Battery Drainer and leave all options selected except for "Vibrate" (don't want to wear out the "vibrator" device just to test battery drain levels!).
3. Get your device down to about 70% on the tablet.
4. Let sleep for (4) hours and report the battery levels.
Here is the full URL for the Batter Drainer app - there is more than one with the same name - please make sure to get the correct one!
https://play.google.com/store/apps/details?id=com.batterydrainer
NOTE: Obviously, leave tablet powered on and "open" while Battery Drainer app is running!

Reserved for test scenario 5

FYI - here are my results after (4) hours in sleep mode with test scenario #1:
After four hours, both my tablet and dock battery were still @ 100%! I'm really interested to the results of the users that had the drain problem (I never did)...
Maybe four hours isn't long enough of a test?
Since I obviously got a head-start on the test compared to everyone else, I'm going to keep my tablet sleeping and check the battery levels in another few hours, just to see what the battery levels are every few hours...

4 hours - still at 100/100

What's next?
Should we try connecting the Google account? WiFi is set to never disconnect by default, but without anything to sync, there probably would not be any drain.
Or we could run the tablet down to 70% and see what happens when the dock starts charging it.

4 hours - 99 / 98
DOCK-EC20N-0207
I turned my wifi off for about two hours because I didn't have wifi connection.

I think 4 hours is plenty! I have done an informal test with my tablet in it's "normal" setup over the last 2 days (wrote down the battery level when putting it to sleep and waking up). While the percentages varied, it always lost some charge over 4 hours. At least 1% - which is totally acceptable with WiFi always on - and up to 5%. Interestingly enough I had the largest drain during a 7 hour sleep (from 97/88 to 68/80) on a hotel network. So far I have not seen that kind of battery loss on my home network.
But that's another scenario - back to our tests:
If it doesn't loose even 1% over a 3-hour period I would say: There is no drain. So waiting more than 3 hours doesn't serve any purpose imo.

I think 4 hours should be enough as well. When I had drain, it was more than a few percentage of loss per hour. I am interested in how the loss changes when the tab hits 70% though.
And what convention are we using for charge level? Tablet/dock or dock/tablet?

Good question! I would say dock/tablet since that is how the icons are displayed.

FYI - I just checked my battery levels after 7 hours of sleep and it's *still* at 100/100!
I like the idea of adding a Google account at this point to see if that makes any significant difference.
Let's do this next:
- Plug device back into power while doing this
- Add a Google account:
- Settings -> Add account
- Select "Google" and "Existing"
- Add account info and leave "Keep me up to date with news and offers from Google Play" checked
- Leave "Keep this tablet backed up with my Google Account"
At this point, go into Settings -> Google account and monitor it while it syncs everything up.
After everything is done syncing and all Play apps have been updated (4 apps automatically updated in my case), go back to the home screen and let's let it sleep for another (4) hours and see if that changes anything (don't forget to disconnect the power cable again!!)
I'll also update the OP with everyones dock model number (for those that supplied it).
Thanks everyone!
EDIT: OP updated with Dock and Tablet version information (except for @ntunix - I didn't get any info from him) - @ntunix - if you recorded the info, please forward it and I'll add it to the OP.
Also, please don't disable wifi or change any other settings during these tests (even if you don't have anything to connect to). It's extremely important to keep the settings exactly the same for everyone!!
So far, only one user actually lost any battery charge during the first test - @drunus - very strange - especially since he turned wifi off for two hours of the test! Don't know what's up with that!
EDIT 2: Updated Test Scenario #2 post with the changes above - Adding Google account will "officially" be "Test Scenario #2".

I wouldn't read too much into that. It's just a couple of % and I don't trust the accuracy of the battery reading very much. 5% or 10% tells us: Something happened. But 1% or 2%.... could be just a fluke.

On a side note: This test makes me appreciate all of sbdags "little" mods and changes for this tablet even more!
240 dpi - ugghhh!
These pesky dock and storage notifications -aargghhh!
I had all but forgotten about those....

Amen to that! :good:
I just remembered that I had an SD card in the dock - perhaps having a card in the dock made it draw more power? For Scenario #2, I'll remove the SD card.

I fell asleep... Scenario #1 after 9 hrs is 100/99. Moving on to scenario #2
Edit: I plugged in and while getting Scenario #2 ready, the pad dropped to 98% then 97%. Both green lights are lit (Dock/Pad) and the lockscreen says charged. I am going to wait for it to say 100% in the settings menu before starting.

I'm a little worried that at a 4 hour interval we won't get much done on one weekend - and I miss my tab already :crying:
I kinda doubt that we get past 4 scenarios here....
Would it be an idea to nandroid this test setup so that we can easily return to it and continue testing with later scenarios?
That would give us kind of a controlled environment to run the scenarios in if and when we might get new ideas to try out.

Yeah, I agree it would be a good idea to Nandroid the setup - or just reinstall - neither will really take that long... The key is to be at the same levels and versions of everything.
I'm just afraid that if we start using shorter intervals, that we wont get accurate results. That and every tester is kinda on their own schedule, so are tests are not 'synchronized', which makes things go slower too... I'm also afraid that if we start changing too much between tests, that we'll lose control of what causes the drain. Unfortunately, it's just a slow, tedious process... I tried to be up front with folks that their tablets would basically be useless for the entire weekend. In my case, I have another tablet, so its not a big deal.
For test 3, I'd like to dock and undock and then let it sit overnight, really with no other changes. Then, tomorrow, we can get the battery level down to say 70 percent and see if the drain results are any different.
So far, in think what we have shown is that the drain is not there with a basic install, at least with fully charged devices. Tomorrow, I want to see if that remains true with not-so-fully charged devices (assuming all previous tests remain 'successful'.
Everyone agree to that testing path? Anything else we should specifically test?
EDIT: by the way, after test #2, I'm still @ 100 percent on both dock and tablet...

TodayScreen which monitors the time how long my PPC charges?

Does anybody know if there is a Today Screen plugin which monitors the charging uptime?
History for my question:
I changed my car and the new Board Computer (BC) doesn't show the time from starting the engine (my previous car BC did it). It was a nice feature and so I thought this could be done by my PocketPC (MDAc) starting the uptime clock when I put it into my active Brodit holder in my car....
You could try this
You could try this software.
Looks good. Will try it. Thanx for your quick response.
I could find any setting in this application to start the clock when charging. Only reset the counter to zero when charging.
Any other apps?
No software available for my request?
sounds like a pretty specific program you want
maybe you should have somebody custom make it for you
seemed to be so.
but is a today screen which displays the charging time such a special thing?
donno never heard about it before
nor have i ever wanted for it before
Contactor-E - it could be written easily enough, but I'm afraid I have no time right now, setting up my website and finishing off another ton of stuff for you guys.
I assume that someone's written one, but I really can't think of one...
V
I will try to start programming my application...
I'll report here about my success.
Some of what you want may be displayed with Beemer's TodayWarrior:
http://personales.ya.com/beemer/todaywarrior1.htm
There are various toggle icons that show: battery %, elapsed time from last charge, charging, estimated remaining battery time, time to 100% charge, battery volts, current (mA), consumption (mW), temperature. There are also icons for power off, always on, etc.
However, I had problems with its WiFi monitoring side (this can be disabled). It would detect the WLAN, but then hang the application and Xda Exec. The extra WiFiKnife utility didn't work, however, my problems may have been because I ran it from SD-card - haven't had time to test further.
Thank you, but TodayWarrior does not support showing the charging time. Only "Charging" is displayed when connected on power.
here's one
it shows the charging time as well as the time running on batteries. also shows battery indicator and device active time (time the device is turned ON and not sleeping).
it can hide or change its size when running on batteries/charging to save screen space.
you can customize it separately for charging/batteries
see screen shorts
have fun.

thanks, RAR did what I told it to do and not what I wanted it to do

Hi zfiser!
Works GREAT !!!!!!!!!!! on my MDA compact !!!!
Wow!!!!!!!
Just installed but seems that this is the application I looked for!!!!!!!
Whrer did you find this app? Did you program it?
Do you know what the plugin number is for?
Thanks again!!!
Yes Works great on my Qtek 9100 under WM 5.0
Thanks for this app
The plugin number is to indicate the height you want for the plugin on the today page.
UPDATE
all right guys, since actually 3 people got it and 2 even got it working, I decided to spent some more hours on it. it's quite fun actually.
so, what is new?
1) AUTOSIZE - the plugin automatically decides its height based on your setting. You can still manually override it.
2) ACTUAL CHARGING TIME - now showing time it's plugged in to outlet and also time the battery was charged for. when the battery is fully charged the time stops and you can see how long it took to charge it.
3) ICONS! yea! I think that's pretty cool, saving you a lot of space on the screen while showing everything, plus it looks freaking awesome!
4) more options - the plug can turn itself to color red when the battery level falls under a certain percentage, set by you. now you can't overlook that your battery is almost dead
5) BUGFIXES, yea, that nasty bug not showing minutes, I noticed too, some minor tweaks
Checkout the screenshots! And have fun. And if you still miss something in this plugin (tetris, nude women, etc), let me know
IMPORTANT NOTICE: You MUST disable the plugin in TODAY screen setting (uncheck the checkbox) BEFORE upgrading. Make sure the plugin does not show on the Today screen before you upgrade!
I made the upgrade this morning => no problem
I just want to say that I had to make a soft reset after installation otherwise the plugin didn't show on today screen.
You've done big improvments since the first version
- good idea the icons to save place
- thanks for the autosize
- I'm going to test it this wee-end but no bug at this time
- what about a log file to keep trace of every data that zfTCT record ? Could be useful I think.

New to the thunderbolt? Look here before posting

I'm hoping this helps out I know with all the hype of the Thunderbolt there's quite a few users new to android that see how people are customizing and wanting to know, and repeat after repeat of questions and bringing a lot of unneeded hostility around here. Feel free to add what ever you guys think is something that is repetitively brought up. I'm running kind of short on sleep, so if I left anything out let me know!
Remember to always follow instructions and SEARCH SEARCH SEARCH before making a new thread
Remember to always Wipe Data/Factory reset/Wipe cache/wipe dalvik cache to insure a clean, fresh bug free install.
Also ALWAYS make a backup of what ever current rom before flashing a new one
Lastly, DO NOT treat the devs with disrespect they are losing sleep/girlfriends/what ever to give us these roms and kernels and everything else for free. If something gets messed up do not come at them with hostility or it will only be returned. The people of XDA will HELP you, but only if you've searched and tried to help yourself first. Also don't forget to donate to the dev's from time to time for their monster/beer/hookers and all their time and effort.

when you reboot the phone make sure you wait until you get a 3G/4G signal. If you start the process of setting up your phone to quick it will cause your phone not to activate the data connection.
2.) ROOTED my phone and at each boot made sure I had 3G/4G connection before setting up phone. (Downgrade and Upgrade).
3.) This let me keep my data connection all the way through.

How to help Improve battery life (Courtesy of Guitarchris123):
If you easily get a full day's use with stock settings, then ignore this. But the ThunderBolt is a powerful 1GHz smartphone made by HTC with a fairly small stock battery, large 4.3" screen, LTE capability, and Sense UI, so battery life may be a concern to you. There is no magic app or single technique that will make your battery last all day with heavy use, but if you utilize some of the following tips you WILL notice a significant increase in your battery life. Everyone's use is different, so 6-9 hours on one charge may be enough for some while others need 12-15 hours. Some of these may not be necessary, appropriate, or desirable for all users, so just pick which ones work for your purposes and preferences. You might prefer to keep using some of the particular features mentioned, as the benefit for you might outweigh the minimal savings in battery life. The point of this is to show people how to disable or limit features they don't need, not force them to shut down everything the phone was built to do. Feel free to add your own suggestions as well or ask any questions about the techniques.
1. Settings: (use an app or widget that helps you quickly toggle them, eg. built-in widgets, or from market such as Elixir, Quick Settings, or MySettings)
a. Screen –go to settings/display, turn down Brightness (20-30%), set Timeout to 30 secs, manually turn off by quickly pushing top button when not using anymore (instead of waiting). I have personally found that I like setting timeout at 1 min better, and manually turning off the screen with the top button every time I am done using it before I put it down or away in my pocket, that way it doesn't waste itself timing out or shut off on me when I don't want it to yet.
b. GPS – always turn off when not using, and plug into car charger (or car dock if you have one) during extended use
c. Bluetooth – always turn off when not using
d. 4G – always turn off when not using, only use when you need the speed, (the TB will get a toggle either in an update or in app form at some point, in the meantime there are several methods to accomplish this)
e. Mobile hotspot – always turn off when not using, plug into charger when in use if you can
f. WiFi – turn off when not near a WiFi signal for an extended period of time, but always use when available (faster than 3G, uses less battery), go to settings/wireless & networks/WiFi settings, press menu button and tap Advanced then WiFi Sleep policy and select“Never”, this sounds counter-intuitive, but it actually uses less power because when WiFi sleeps 3G or 4G wakes up to sync, get email, and retrieve other data (WiFi connection disables 3G/4G). Also uncheck Best WiFi Performance if its checked.
2. Background/wallpaper - use a static image instead of a live wallpaper (but these are cool, so use one if you really want to, they only drain for the short amount of time you are looking at the launcher screens). Many say the live wallpaper drain is minimal, but I noticed a significant amount while using a live one so I went to static. Have any of you tried both and noticed much of a difference yet?
3. Window animations – go to settings/sound & display/animation and select“no animations”
4. Keyboard vibration – turn off vibration function (haptic feedback) for when you hit a key (helps with speed too), go to settings/language & keyboard/touch input/text input and uncheck vibrate when typing, you can disable haptic feedback in other areas of the system by going to settings/sound, and uncheck vibrate feedback
5. Notification lights – unless you really want/need to know when something happens on your phone when you are not looking, go to settings/display/notification flash and uncheck all the boxes
6. Vibration – unless you really want this function, go to settings/sound, and uncheck vibrate
7. Monitor battery use - go to menu/settings/about phone/battery use, this will show you what is eating the most battery, uninstall troublesome unneeded app, use Running services widget by going to shortcut/settings (helps identify processes running in the background and foreground), if you want more detail check out SystemPanel in the app market, if you want to be alerted to "rogue" apps check out Watchdog Task Manager in the app market
8. Disable“always-on mobile data”– go to settings/wireless & networks/mobile networks, uncheck “Enable always-on mobile data,”you will still receive emails, texts, and phone calls, as well as internet usage, but it may cause connectivity problems in some third party apps (use manual refresh feature when opening apps to update online data)
9. WiFi and 4G network notifications – go to settings/wireless & networks and uncheck Network notification box (so phone will not constantly scan to look for open networks to tell you about)
10. Background data – if you are not using Google life-management services, go to settings/accounts & sync and uncheck Background data box (so that apps cannot sync, send, and receive data whenever it wants to, even if not currently using them). Add a homescreen shortcut to quickly toggle this (allows you to update/sync only when you want/need to).
11. Auto-sync – uncheck Auto-sync in settings/accounts & sync, or at least limit what apps are set to sync, it is better to manually sync/update/refresh in the app when you open it (set to update at launch), set update/notification frequency (polling schedule), if you do not want to turn off auto sync, just change widget or app update/notification frequency (refresh interval) in settings/accounts & sync to 30 mins or 1-2 hours, or better yet set it to update at launch, useful for Facebook, Twitter, Flickr, news, weather, Google apps, and stocks, be sure to manually sync/back up your contacts every once in a while in case you lose your phone or break it
12. Email – change sync option in settings, set email check frequency to 30 mins or 1 hour, or as items arrive, or better yet set it to never and manually refresh when you want to check/read your email
13. Camera app(s) – make sure they are not running in the background when not in use, exit/close when done
14. Video chat app(s) – make sure they are not running in the background when not in use, exit/close when done
15. Streaming app(s) – make sure they are not running in the background when not in use, exit/close when done, try to limit use or plug into a charger during use if you can
16. Google Talk – press Menu then tap All apps/talk/menu/settings and uncheck automatically sign in, make sure you exit the application by going to menu/more and selecting sign out when you are done (exiting the app by pressing home or back keys will not sign you out), if you want to receive IMs just open the application again
17. Adobe Flash Player – open browser, hit menu key, go to settings/enable plug-ins and set it to“On demand”(this way the browser only loads flash content when instructed to do so)
18. Update apps – hit menu key and to go My Apps to check for updates, even if you have selected“update automatically”because some apps require you to manually install updates (apps often get updated to use less power)
19. Location settings (updated) – go to settings/location settings. It is ok to have all of these checked, because it is the apps that use the GPS and consume power, not having these settings selected. GPS is only active when apps using it are in use.
20. Task killer – do not use them, uninstall if you currently have one, can harm phone and consume battery, just use back arrow key to exit apps instead of home key, simply monitor rogue apps instead and uninstall/replace. These are especially bad on pre-installed apps and services (many things rely on each other), so never "auto-kill" or "kill all." If you must use one, only use it on apps that you have installed that are misbehaving, otherwise let Android do it on its own.
21. Anti-virus – do not use them, uninstall if you currently have one, only download and use periodically or when you suspect a problem, do not download suspicious apps (check reviews and rating in market first)
22. Ad blocker – do not use them, uninstall if you currently have one
23. Battery meter accuracy – go to data/system and delete“batterystats.bin”after you have charged your phone to 100%
24. Tasker – can be used to automate settings (eg. based on time of day or app launched)
25. Juice Defender + Ultimate Juice – can be used to automate settings (eg. based on time of day or location)
26. Screebl - keeps backlight on while holding phone in "use" (vertical) position and turns it off when laying flat
27. Rebooting - reboot phone every few days
28. Delete unnecessary apps – determine which apps you do not need or use anymore and uninstall them, determine which apps you keep are causing the most battery drain and see if a comparable replacement from the market will do better
29. Widgets – turn off animations, do not use too many of them (choose them wisely), and delete unnecessary ones, they pull data in the background. At least make the interval/frequency of sync/updates longer for the ones you have. It may be better just to open some apps themselves instead of using the widget. Disable auto-updates on HTC Weather widget or at least set it to every few hours, manually update by tapping update icon on bottom of widget. Note that widgets that display battery, CPU, and memory utilization consume some power because they are polling the system for information.
30. No service – turn off phone or go into Airplane mode when you are in an area that does not have cell service
31. Chargers – have them handy at home, at work, and in car, and plug in when available. Try to get a 1A charger (same as included wall charger), many cheap aftermarket car chargers are only 500mAh and will not be enough to handle the GPS. VZW's car charger is 750mAh.
32. Rooting – (there are a lot more techniques that can be used with a rooted phone, such as removing bloatware and underclocking when then screen is off, but I will save that for a later thread)
33. If all else fails, buy an extended battery or have a spare handy just in case
Update1 - I came across another technique, it sounds a little strange but it apparently came from HTC regarding the EVO...some users appeared to have experienced gains from it:
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally. Repeat once a month or so.
Update2 - I found a few more things to suggest
35. Blockbuster app - open app, download update from market, then go to menu/settings and tap "disable movie updates." The app is set to automatically periodically scan for updates by default, and requires the new update to turn this off.
36. Friendstream - delete the widget from your home screen, open app and go to menu/settings and select update when opened. This way it isn't constantly refreshing, but rather only does so when you want to look at it by opening the app.
37. Signal strength - whether 3G, 4G, or WiFi, if whatever you are trying to connect to has a low signal strength the TB's battery will be draining trying to connect. Keep an eye on your connections, and try to be aware of when you are in poor signal areas and toggle off or switch connections if you can. Also keep in mind where your "fringe" areas are (ie. bounces between 3G/LTE/1X)
38. Apps - not all 3rd party apps are optimized for the TB, be sure to read reviews/ratings in the market to see what problems other users have had with them. Monitor your apps to see if any of them are hogging system resources (eg. CPU, RAM) and draining your battery, and delete or replace them accordingly. And remember to set the sync/update/notification frequency at longer intervals in settings within the apps that connect to the internet frequently.
39. Power saver - go to settings/power, and check enable power saver, the go to power saver settings and tweak (basically does a lot of the things we've talked about here for you automatically when you get low on battery, in case some things are left on or on higher settings than needed)

Thanks for that. I am going to have my wife read this so she can understand more on what to do with her phone, since it is not rooted and still has all that bloatware.
My phone is rooted and I have been testing with 4gLTE off/on, and seriously gained 5 hours when 4gLTE was turned off.
17-18 Hours Almost made it to 19 hours - 4gLTE off - This is with moderate use call/text/IM and some gameplay.
13-14 Hours - 4gLTE on - This is the same as above.
Trying now to talk my wife into letting me root her phone, but alas it is her phone and her choice.
Also if you want to update there is a 4G/LTE app in the Marketplace for the toggle - just search in the Market - LTE - it will show up as a Red Lightning bolt in a grey Circle.
Excellent post!

Ah, very good! I forgot about the toggle switch. Added and thanked!
Lots of good info, thanks
Awesome, thanks for the tips, should make my experience better.
This is a great post!! I def used some of the battery saving techniques.
Awesome information - wish I would have found this when I first bought my Thunderbolt... better to learn from others than trial and error method sometimes. lol
Thank you for the info... Somw i knew some i didn't... Great one stop for quick reminder..

Great post. Just one question. Why do ad-blockers use more battery? Wouldn't it decrease data use and thus battery since it prevents ads from being downloaded?
Thanks for the info!!

[Q]Galaxy Tab 2 7.0 frozen every morning after charging/sleeping, help?

Hi All,
First - I'm new - but I did plenty of searching and found some similar problems, but nothing quite the same. Most are really old and this is with a newer Tab with ICS stock on it so most I felt didn't apply.
I just got a Galaxy Tab 2 7.0 a week ago. I'm very happy with it except for one constant annoyance. Every morning after charging all night I have to hard reset the tablet. When I press the wake button I get the splash screen, but it's very sluggish and never responds. Sometimes I can swipe it away but the desktop never comes up.
I believe it to be something I've installed but I need some help to figure out what because of the troubleshooting steps I've taken. Here's what I've tried so far:
Factory Reset - after doing this and charging overnight this did *NOT* happen. *This leads me to believe that it's an installed app and not a hardware or OS issue*
After Factory Reset I tried restoring my apps manually instead of automatically via my Google account. No difference.
I was selective about what I restored - didn't just get EVERYTHING. Still no difference.
I am charging using the supplied cable and charger that came with the tablet
Wifi is on and there is a 16GB MicroSD card in the device every night.
I tried using a different launcher (both nova and apex) thinking it might be something conflicting with Samsung's SecLauncher but no improvement.
Since the issue I have rooted the device, but this same problem was happening both before and after. I believe I have a rogue process either memory leaking or eating CPU cycles that prevents me from even waking the device fully - and so far I can't figure out what it is. I have three questions for the group:
A) Any other new GTab 2 7.0 users with the same issue?
B) Is there an app I can run that polls my CPU/memory and running app usages to a text file every few minutes so that I can reboot and see what was going on right before I rebooted?
C) Any other info I can provide to help figure out WTF is going on?

Device Summary
Device: samsung GT-P3113
Android Version: 4.0.3
Build: IML74K.P3113UEALCB
Applications Installed: 40​
I just got my tablet today, so I can't really say if I will or won't experience this, but maybe you can try killing processes before you go to sleep, or selectively killing things to see if the problem is fixed. It will take time, but sometimes troubleshooting is simply a pain in the ass.
After the tab charges the charger needs to be removed....Or you would have to reset.....
On another note this tab is it resets when it gets a few degrees over running temp
p-3113 Puff, Puff, Puff,...... just sende'n smoke signals
hi, well there is something I can't understand, why didn't you return it after one week, you should have consider to take it to Samsung before rooting it.
there is plenty of applications who can provide a complete report about your processes, just type cpu diagnostic or process log in Google play.
and I think you can unroot it, then let the people who are already paid by your warranty do their job.
If I helped you, please press the thanks button ;-)

I don't believe it's an issue with the hardware or OS - I think it's something I've installed. I don't need to return something that's not defective because when I factory reset it it doesn't do this.
I'll try those searches you suggested.
I have seen this happen to my Galaxy Tab 2 (7) every once in a while. What I have noticed using the app "Watchdog" is that there is a system process (I am at work so cannot access/remember it) that every once in a while chews up 40-60% of the processors juice(Could be a TouchWiz process... i wouldn't know) ... This thing should fly once we have it rooted and once we have our devs clean it up and get some cleaner roms out
Hang in there mate... Good times are about to come
Totally - waiting for some CM9 on this.

This is bull. I'm supposed to babysit my tab and unplug it when it's full, or it will freeze and reboot? That's ridiculous.

I had my tablet plugged in overnight and when I woke up, I didn't get the freezing issue, so I think its just the OP and not necessarily a wide spread problem.
I've been having seemingly random freezes and about once every two or so days. It's kind of annoying--at first I thought the battery was dead, but it seems it's a common thing. Might head back to Costco to swap for a different one.

I purchased this as my second tablet, first being a Kindle Fire that I did everything to. But I love this thing!! I have not rooted yet, waiting for CM9... I always have the SOD after charging or not using the Tab for a long period of time; this is my fault for not conserving battery and just turning it off. BUT! SOD's are a pretty much a grantee that I have noticed with ICS tablet platforms that I have experienced so far. WHY? I do not know. I have also noticed that after playing any games for a lengthy time, they suddenly go into a glitching mode, as if the processors are just worn out.
Those are just a couple of things that I have noticed. Let me know any suggestions.
Tweaks that might be helpful
JimmyO:
Why not go back to stock, with factory reset , and run your tab for a couple of days (and nights) to determine whether you have a base problem. If you do, take it back or contact manufacturer. If not, as you have already indicated. then the problem is, allmost without doubt, bad software. In that case you may need to just load no more than half a dozen "essential" apps, try them for several days; if problems then remove them one at a time until problem is solved. If no problem, repeat the process with another half dozen apps.
You have a wide diversity of apps, many of which may auto-refresh. I would suspect one of these is mis-behaving.
The following is a response from Michael S to a string of negative feedback comments on the SGT 2 7, recently published by an individual on Amazon.
Michael is obviously a very savy guy, as his comments provide numerous tweaks that every SGT 2 owner (and most ICS users) should be vividly aware of. This info may help you to solve your problem, and get the most out of your SGT 2 7".

Michael S says:
Right now my Tab 2 stats show the device is going 2 days 14 hours on a battery charge with 43% left. I use the Tab a few hours a day web surfing, doing research, checking and responding to emails. There are a number of ways to save juice so I'll mention a few that I use; which some, all, or none, may be applicable to others' situations:
#1 - Go into "Settings", then "Wi-Fi". At the top right-hand side there is a icon of "3 bars and a small triangle" (basically an option button) click on it and and when the "Advance" box shows on the screen, click it. Then click on "Keep Wi-Fi on during sleep" then check "only when plugged in". This will turn off the Wi-Fi when in sleep mode & running on the batteries. I use a login pattern to unlock my Tab and every time I unlock the screen it states "establishing Wi-Fi connection" I'm using WEP2 encryption on my network and the Tab starts Wi-Fi within seconds of waking from sleep. If one wants their Tab running multiple apps and to always have the most up-to-date information "pushed" to the device even while sleeping and running in battery mode, then one has to trade battery life for always-on information. The Wi-Fi will be active in sleep mode when it is plugged in. If you Always want the Wi-Fi off when in sleep mode then select "Never" instead of "Only when plugged in".
#2 - I mostly use my Tab at home or at the office. I have both Wi-Fi network settings saved in the device, so I turned off "Network Notification" in the same area as # 1 above. This stops the Tab from periodically searching the Wi-Fi Network for "Open Networks". If I go out and want to connect to a Wi-fi hot spot, I simply turn this feature back on.
Note: When you are in "Settings" and "Wi-Fi" mode you will notice that periodically the device shows "Scanning". Because you are in Wi-Fi mode, it scans to refresh the wi-fi networks its found, to help you connect to them. It does not continue to scan the network after you leave Wi-Fi settings, unless "Network Notification" is turn on, although the scan intervals may be different between the two modes.
#3 - In "Settings" then " Location Services" make sure "Use GPS Satellites" is unchecked. This requires more battery and a clear view of the sky, and is really only useful outside.
Those 3 settings will make a difference in battery consumption, and will not affect most people's use of the Tablet, although others' actual mileage may vary
#4 - In addition, as I stated earlier, I mostly use my Tab 2 at work or home, so I always know where I am. Therefore, I also turn off "Use Wireless Networks" (Found in the "Location Service" section). This use Wi-Fi to help determine your location for Maps and such. If a App or Apps are running in the background and they have a location feature, this stop them from updating while the Tab is sitting idle, or your while your using other apps.
#5- Because I use my Tab mostly at work or home and I know where I am, I usually turn-off GPS. Click on the "Clock" icon at the lower right-hand side, and then uncheck "GPS". If I ever need it, I quickly turn it back on.
#6- In "Settings" "Account and Sync" I have "Auto Sync" turned off. I turn it on when it's plugged in and then have it Sync. Then I turn if off once its done charging and back on battery power. I usually sync only 1-2 per week, same as my Skyrocket.
#7- Next, in "Settings" then "Developer Options" (I don't run a bunch of Apps and don't use a lot of "Notifications") so I check the box "Do not Keep Activities" This means when I leave an App, ICS closes the app instead of letting it run in the background, possibly sucking more juice. I saved this one for last, as it impacts the tablet operation the most. If a person uses "Notifications" or likes to multitask with many apps running and want to quickly switch between them, then thus option is not useful. What it does do is free one up from going into "Task Manager" and closing down a bunch of Apps you thought you closed but were only minimized when you exit-ed the App.
#8- Lastly, Usually the biggest drain on the battery is the display. Currently under "Battery" in "Settings" the Display has consumed 65%, with the next closest item "Internet" at 19%, and "Android System" & "Android OS" at 5% each, with everything else at less than 5% combined. Unfortunately, I'm unable to recommend the "Auto-Display" mode, as for me, it makes the display too dark most of the time (click on the "Clock" icon and then check the "Auto" box to engage).
I keep the display setting at about 20-25% as I mostly use the tab 2 indoors. As mentioned above, others' actual mileage may vary with Auto-Display turned on. I use Auto-Display on my Skyrocket, as I use it equally indoors and outdoors. When indoors, I find Auto-Display too dark also, but I live with it because when using the Skyrocket outdoors I find the Auto-Display is a must to see the display in bright sunlight, and therefore watch the battery drain accordingly. To compensation for this, I replaced the stock battery (1,850 mAh) with an extended battery (2,250 mAh) for a 22% capacity increase. This is obviously not a option on the Tab 2.
Hope this is of help!! I know it was to me.

[APP][ROOT][4.0+]Battery Charge Limit v1.1.1

Please read the following before installing the app:
This app requires a rooted mobile (Android 4.0 or later)
Before uninstalling the app, disable limit in the app (if forgotten, reboot after uninstalling)
Usage instructions and app details:
Enable limit in the app
Change the limit up to which it should charge (default: 80)
Check which control file suits best for your device, see Q/A section below for hints. In most cases, the pre-selected choice should be the best that's available for your device.
The app only gets kicked in while you connect a charger (or USB), and automatically closes shortly after unplugging charger (or USB) i.e it only runs in the background as long as it is plugged in, and won't affect your battery life.
If your device is not charging even after disabling the limit (which shouldn't happen, just in case), uninstall the app and reboot the device (The changes made by the app don't survive a reboot). Your device should charge normally then.
If the app says "your device is not yet supported"
There are various control files in different devices (due to OEMs), and toggling the values in them (0 and 1) makes it possible to enable and disable charging via software (might not be possible for every device), though the charging cable is still physically connected.
Since we cannot own every device, it is impossible for us to find every file. We can support a lot more devices with information provided by testing possible files on different devices by you, the people in the community.
Hence, for support to be provided to other devices, you need to do some detective work to find the files on the respective devices. Please refer to this file for control files of currently supported devices, so you can know where they are generally present: https://github.com/sriharshaarangi/BatteryChargeLimit/blob/master/app/src/main/res/raw/control_files.json
You can send us a pull request or open an issue on GitHub. If necessary, you can also post the name of the device and the file here.
FAQ
Q) Can you please add support for... (insert arbitrary device name here)?
A) Maybe, but we need your help. Bottom line, this app does nothing but modifying the content of a certain "control file", some more details are given above. If you find such a control file for your device, please let us know (ideally, open a GitHub issue here: https://github.com/sriharshaarangi/BatteryChargeLimit/issues) and we will add support for your device.
Q) I think I observed a bug. Can you fix it?
A) We'll do our best, but we need your help: Please open an issue on GitHub (https://github.com/sriharshaarangi/BatteryChargeLimit/issues) and provide as much information as possible about the problem.
In most cases, we need the "logcat" logs of your device to find out about the exact issue. In order to provide those, you could use aLogcat (https://play.google.com/store/apps/details?id=rs.pedjaapps.alogcatroot.app).
FOR CHARGING-RELATED ISSUES: Select the "Time" format in the preferences of aLogcat, so we can see precise timings, and filter for "(Charging|Power) State" with "Apply as regular expression" ticked.
FOR CRASHES: Please also select the "Time" format and provide unfiltered logcat data that includes the stack trace of the crash.
Q) Why do you want to limit charge to a lower capacity?
A) In short, to prolong battery life in long term usage. For more information, refer this : http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Q) How does this app work? Does it modify something in the ROM/Kernel to stop charging?
A) It writes "0" or "1" to a control file that represents some state of the power supply hardware, as simple as that. The file is normally read-only, so you need root to overwrite it.
The change might be automatically reversed by the OS if the power supply situation changes. Anyway, it should never survive a reboot of the device.
Q) I can select multiple more than one control file in the radio group. Which one should I use?
A) For most devices, battery_charging_enabled or store_mode are preferable. Try those first and see if it works. If you observe any bugs, try another file.
Q) I have a OnePlus device, and the app doesn't work correctly for me. What to do?
A) Check that the control file you selected is NOT battery_charging_enabled! Although it should be preferred in general, there are known issues for this file with OnePlus devices.
Q) I use the store_mode on a Samsung device. My device always stops charging at 70 % (or other specific percentage), no matter what limit I have set.
A) The store_mode implementation differs among the supported (Samsung) devices.
Normally, it freezes the level at the current percentage when store_mode is triggered until the cable is unplugged for some seconds. This is a normal condition due to Samsung's kernel implementation, it's not a bug of this app.
If this is a problem for you, try to switch to another control file (e.g. batt_slate_mode), if supported.
Q) How does the "automatic stats reset" work?
A) The automatic reset should perform a stats reset when your power supply is removed while the battery level is within the desired range. Everything else is wrong behavior.
Q) No matter if I the "automatic stats reset" is enabled or not, my phone is always resetting my battery statistics. Why?
A) Are you using a threshold above 90%? If yes, your ROM will most likely clear the stats when the power is removed. There is nothing we can do about that.

I can't believe it. You can't imagine how long I was looking for such an app .
Will try it!
I remember this was a feature that some kernels had years ago, and I would limit the charge to 85%. On my laptop I can cap it to 60%, which is great because I leave the charger in often.
Anyway, thank you for making this app!

Unfortunately it does not work as it should :/. It doesn't really limit. Even when I unplug the notification doesn't go away as you mentioned.
I have a HTC One M8, android 6.

Does the battery percentage continue to rise beyond the limit? Regarding notification, it doesn't immediately go away after unplugging. It goes away after the percentage drops 3% below the limit. It is to ensure that the phone again charges to the limit if the phone is still plugged in. If it is not plugged in, then notification closes.
very good idea, thanks for app, was looking for app like this for a long time will report in half hour if app works
thanks!I always was searching such an app cause:
1)I read if u charge your battery till 80% it will last more time..
2)At the end of the day,I always have 40% battery left and I cant trust my phone for the next day without charge.
Thanks again It works on my moto x play!It stopped at 79% but its ok not such a big deal!
ok, so it worked, but first time, when i unpluged and pluged app didn't noticed pluging and continued charging. after that i tried several times and it worked again. so there should be somewhere bug in monitoring pluging charger sometimes is left unnoticed.

Seems to work on my LeEco Pro 3. Charging icon switched to normal battery at 80%.
This is what I have been looking for!
Thank you for the app!
I tried it and its stop charging after 95% ?
Im on xperia z5 Nougat.
But the notification doesnt go away when I unplug the charger's cable from the phone.
Turning off the app but did make the notification disappear.
Another question.
Does it really stop the charger from giving electricity to our phone?
Or does it only change the charging status?
Im scared that the app tells that it stopped charging, but the electricity is still going on.

Can somebody explain to me, why someone would want to limit the charging current?

1. Regarding notification, (I have updated the OP as well):
The app only gets kicked in while you connect a charger (or USB), and automatically closes shortly after unplugging (not immediate, it closes after percentage drops more than 3% below the limit because the app doesn't know whether the cable is physically connected or not, since we disable charging at the limit. So, after it drops below 3% and (a)the charger is still connected, it charges again to the limit, and (b)if it is disconnected, then the notification closes) .
So, it is not a bug.
2. Does it really stop the charger from giving electricity to our phone?
It actually stops charging at the limit. It is in the same way any phone automatically stops charging when the battery reaches 100% capacity.

Is it possible that some kernels aren't compatible with this, or even certain SoCs? I have a Kindle Fire with a mediatek, so I'll test the app on there later.

Maybe I'll try another kernel. Anyway I wanted to change my rom . Actually it's always the other way around. Other people have Bugs except me, this time I have no luck haha.

I don't know the reason(I don't think this is kernel dependent), but this file is the key: /sys/class/power_supply/battery/charging_enabled
It should be 1 by default. And when it reaches the limit, the value is made 0 by the app.

Originally posted in [ROM][UNOFFICIAL][11.0][N7100][Samsung Galaxy Note 2][LineageOS 18.1][ALPHA][TREBLELIZED]:
I just flashed the newly Android 12 LineageOS 19 build this morning.
It's currently a bit early to share my experience yet since I need some more time, but I already like to share my first impression.
First of all, I was surprised that I could just do a dirty flash over your current 18.1 dec build without any problems.
I did not perform a clean flash because I couldn't backup my Session messages, normally I always perform clean flashes.
I used TWPR 3.5.2 custom recovery to flash this ROM and only wiped Cache and Dalvik Cache/ART partition.
Everything went smooth. It didn't take too long for the first boot either.
Right after the first boot, just when it was booted, the phone rebooted.
After this reboot, I didn't encounter any random reboots yet.
Everything seems working smooth and snappy at the moment.
I can confirm that Magisk 23 is still working on this ROM. You just need to re-flash it after the first boot.
The only annoying thing I discovered is a blinking LED issue and the battery that last less longer, but that's maybe linked to the blinking LED issue.
Something I immediately noticed is that my notification LED is actually red now while charging and green when it hits 100%.
In previous 18.1 build, the LED always got a weird yellowish colour while charging.
Another thing that caught my eye was "Google Play System update" in settings.
I don't understands why it's there since it's supposed to be a degoogled ROM.
Google Play System updates is a part of the Google Play Services ecosystem.
I didn't install any GAPPS and this ROM didn't came with GAPPS pre installed.
Spoiler: What I can confirm is working
- It (re)boots correctly
- Able to receive and sending sms messages and phone calls (didn't try SIM unlock yet. I used the workaround that is mentioned in the main post)
- Camera's
- Wi-Fi (both, 2.4 GHz and 5GHz)
- Video's (YouTube in browser)
- Sensors, except compass (phone rotates correctly)
- Charge correctly to 100%
- S-pen (just as a regular styles, no button functionality)
Spoiler: What is not working + bugs
- An annoying blinking LED issue.
I never experience this before on any ROM.
Can be a coincidence, but after the battery drops below 75%, the notification LED is constantly blinking red, even when the screen is on.
I already tried to literary turn off all notifications options. I even disabled blinking LED option, but it still keeps blinking, even after a reboot. It only disappears after fully charging the phone but will come back in time.
I didn't find a way to fix this.
- Android 12 theme engine seems to be broken.
Some things like buttons (like emergency call button on lockscreen), text (search apps in launcher) and backgrounds in notifications icons in notification panel are still LineageOS teal.
Switching a wallpaper with different colours, but it doesn't change the theme colour of the device. Buttons, lockscreen clock etc. are still light blue. I try to add some screenshots to highlight this problem.
Also, the options to change the icon shape seems to be gone, even in developer settings.
Everything turned into circles after the update. Can't change it.
- USB (can't connect to pc (MTP))
- Extended screenshot beyond your screen
- There was a weird issue that my device is stuck at Samsung Galaxy II screen when turning on the device (not the LineageOS boot screen). I only had this once so can't describe how to reproduce it yet.
I just turned off my device in the power setting inside the ROM. The next time I turned on the device, it was stuck on that screen for 10 minutes. It was fixed by simply holding the power button for a while to turn off the phone.
After doing this, the phone rebooted normally again. I didn't got this issue again.
Besides the blinking LED issue, I had a very good first impression.
I really don't mind that some gimmick features are not working.
I only have this ROM for a few hours, so please keep in mind that I need more time for extensive and more in-depth testing.
Maybe there are some critical problems that I still need to discover.
I just wanted to give a quick update.
@html6405
If there are some specific things you like to try or things I need to keep an eye on, please let me know.
A big thank you to html6405 for this rom! Almost everything seems to work good.
The only thing i am missing is wake by proximity sensor. I use the app Waveup from F-droid for this. I know from trying other roms, that this is an unreliable feature. The sensor hardware is working, that much i know.
When using Lineageos 16, this is a built in feature in the rom, but it deactivates after every reboot. I have to manually turn it off and on every time to get it to work.
No big issue. Just glad to have latest Android on this device. I hope you get more appreciation from this than what you got from your Los 18.1 thread.
Let me know if you want feedback of any kind.
Happy new year!
​
It does work! I couldn't resist trying the future LOS19.
The overall impression is quite good, as the system seems to be more stable than the previous LOS18.1 for this phone. Still, the development options screen hanged a couple of times. At some point the system crashed and kept rebooting into recovery - fixed by erasing data partition. GPS works, although not well enough. The compass doesn't work in GPStest, but works in Compass app from Fdroid. I tried web browsing and viewing HD videos with Brave browser - very smooth experience. In order to access files on the phone I set up default USB mode in developer settings to files.
Two preinstalled applications are unsafe, contain trackers: camera and via. These had to be removed. Open Camera from Fdroid is installed - it works. The system web browser is preconfigured to ring Google; one may want to review its settings.
Installed Insular app (a sandbox made of the work profile) from Fdroid. The work profile works, but looses its filesystem after disabling and enabling it again. To bring the filesystem back reboot is required.
Phone encryption doesn't work, sadly. This is the same as with many previous custom ROMs for this phone.
A strange horizontal bar is seen at the bottom of the screen (nav bar home button??). Disable "Navigation hint" to get rid of it.
All together, it's an excellent result for the first attempt on LOS19. Looking forward to further releases!
Happy New Year everyone! Thank you html6405 for such an exciting present!

This are really great news, could some one else confirm that GPS is working?
I cant test it by my own...
If it's working fine, I will add it to the working list.
GPS seems to work better with "Force full GNSS Measurements" and "Use GNSS APIs" disabled in GPSTest. I also disabled "Force full GNSS Measurements" in "Developer options". From inside a room it locks on 3-5 satellites, although sometimes after a delay.
With GNSS it finds also Russian and Chinese satellites, but uses only the US constellation.
GPS performance, of course, is not as impressive as in new Samsungs, which lock on several constellations at the same time.
----------------
Added later... Still, GPS is not working well enough in this first release. It finds satellites slower than my ancient HTC DHD (ace) running cm13. Then it locks and in a moment loses the lock. I'll look into this in more detail...

Great, hopefully some one else can confirm this , you're the only person so far.
Yes indeed - working GPS very important, and needs to be confirmed by multiple sources.
But kudos to the developer for making progress on this.
hello, dear! tell me, what is the battery life? I use rr 5.8.5, the battery lasts for a day of average use. I tried to install lineage 16 - the battery was enough for several hours( now I would really like to switch to this rom, but everything depends on the battery life. thank you for the answers!

Just tried: flight mode, screen off, location off, BT and NFC off, no GApps, just sitting on the desk starting with fully charged. After half an hour the estimated battery life is 10h, 6m. Not great. The battery felt fine last night for a couple of hours of experimenting with secure messengers, then fully charged, then down to 2% by morning. I'll try uninstalling the messengers in case they are draining the battery - wait for an update.
I could not find a way of disabling the clock on the sleeping screen. It disappears after a while, but the screen power consumption is suspect.
Well, this is the first alpha release, the things with power consumption might improve soon.
----------------
Update: I found a way to disable the clock on the sleep screen and the battery life increased to 23 hours, mobile network 1% (still the flight mode is on), phone idle 1%.
The method to disable the display was to press the power button while the notification panel is open...- perhaps another bug.

The always on display will be turned off in the next build, this will improve the power consumption a lot.
You should be able to disable the always on display in the quick settings (AOD) and give your test a retry .

Just tried the AOD button: first enabled it and then disabled again... - it worked! Not sure, though, whether any of my previous attempts to modify the settings via adb played any role. I'll repeat timing of the battery with this setting. Thanks.

Theoretically it should be enabled by default (what I will change in the next build for sure), but anyway, it's good if you can turn it off yet.
Great news, another person confirmed with a video that GPS is working ,
so I will add it to the working list.
Nice to see, that this worked out nearly blindly, because I have no testing opportunities...
With AOD button on then off the battery life is estimated as "more than 2 days left" (flight mode, idle). Let's wait for a little longer...
-------------------
Update: after 11h it predicts "5 days left" and counting! Very good! The graph shows slightly increased power consumption in the first hour, and then it goes almost horizontal. I think it will be more than 5 days at idle, perhaps twice as many.
-------------------
Further update: after 1 day 5 hours it says 9 days left. The way the graph in Battery Usage page goes makes me think that it will last about 20 days if left idle. I don't know what caused the quick discharge in the first hour; after that the graph is a straight line pointing beyond 20 days mark...
-------------------
Yet another update: 28 days predicted after 23 hours of idling. Very good! This is with all wireless interfaces off, Always On Display off and NavBar off.
For reference - Note 4 with cdDroid 9 under similar conditions reports 45 days.
I checked this rom. the sd card is not mounted as internal memory, the phone falls into the bootloop before the lock screen, after which the bootloop again. wipe data or format does not help
-----------------
udp. the backlight of the hardware buttons does not work, although it is enabled in the settings
-----------------
upd. the indication of charge percentages in the status bar does not work when the display is selected with a circle inside the icon

Simply remove the sdcard.

You're right, this will come later from lineageos.

Ok, this will also be fixed from the linageos side.

now I use the 7100 as the main device, I actively use it, I can quickly share bugs if I find them. is it possible to contact you directly without communicating on the formum? do you use a group of testers in telegram?
