[HOW TO] Fix Your Skyrocket's Battery Life

I’m going to try to consolidate a lot of battery information in this thread and prioritize it. This is a WIP.
1) Check your charger first!!!
2) Fix wakelocks
3) Remove bloatware
4) Replace your battery
5) Try a new ROM
The Charger Problem
Using certain chargers causes a wakelock on your phone that prevents it from going into deep sleep. This results in roughly 10% battery attrition, regardless of activity or screen on time. Before you try anything else, you should test each of your chargers and make sure they aren’t causing a wakelock.
Do you have this problem?
Install CPU Spy from the Play Store. Open the app to see how much time your phone spends in each CPU state. If Deep Sleep is a very small percentage, or Deep Sleep doesn’t even appear, you have a problem with your charger. Follow one of the methods below to test each of your chargers.
Charger Test App
I've created an app with the sole function of reporting your charge type and current. See the thread below to download and install the app.
UPDATE: This app is now available on the Play Store for easier installation: https://play.google.com/store/apps/details?id=com.jellisapps.srchargertest
http://forum.xda-developers.com/showthread.php?p=29451951#post29451951
Testing with only CPU Spy:
1) Plug your phone into the charger and turn the screen off. Leave it charging for about 30 seconds. (Don't do this with a fully charged phone, as I don't know how that affects the testing)
2) With the screen still off, unplug the phone from the charger.
3) Open CPU Spy, hit the menu button, and "Reset Timers". Turn the screen off.
4) Let the phone sit idle for a few minutes with the screen off.
5) Turn the phone back on and refresh the timers in CPU Spy (menu button again).
If Deep Sleep doesn’t appear in the list of CPU states, your phone is experiencing a wakelock brought on by the charger. It’s probably spent the majority of time at 192mhz or 384mhz.
To further confirm this, leave your phone unplugged, restart it, leave the screen off for a few minutes, and then check CPU spy again. You should now see it going into Deep Sleep.
It’s rumored that some USB cables can also cause this problem, even if used with a good charger. I have not experienced this with the cables I’ve used.
Testing with Terminal Emulator:
This method will not show the wakelock, but it will show you what charging mode the phone is in. Because I’ve identified the problematic charging mode that creates the wakelock, this method can be used to test your chargers fairly quickly. (Thanks to pj_rage)
If you have Tasker, you can download and import my Tasker profile that will check the charger when it’s connected and toast you with the charger type. It will also pop a notification if the charger will create a wakelock. Profile: https://www.dropbox.com/s/jewrvalkc7agtoz/Charger_Type.prf.xml (hat tip to Note-owner G8351427 for the Tasker idea)
1) Plug your phone into the charger you want to test.
2) Use your favorite terminal emulator (ROM Toolbox has one) to run:
cat /sys/class/power_supply/battery/charging_source​
3) Look for your results:
0= No charger connected.
1= USB Normal Charge. There is 5VDC on pins 1&4 and data current is detected on 2&3
2= AC Fast Charge. AC Fast Charge. There is 5VDC on pins 1&4, and pins 2&3 are BRIDGED.
6= AC Regular Charge. This is the charge state that creates the wakelock. There is 5VDC on pins 1&4, and pins 2&3 are OPEN/DISCONNECTED.​
Thanks to SR-owner nighthawkmckenzie for additional information on charging states.
Known Workarounds:
If you can't use a proper charger, there are two known workarounds.
1) Restart your phone after charging. This is what I did for a while, until I found one of my chargers that works with the phone.
2) Plug your phone into a "Type 2" charger. If your phone is plugged into a Type 6 charger, it creates the wakelock upon disconnection. But if you plug in a Type 2, even briefly, it clears the wakelock. For example, I would charge my phone overnight on a Type 6 charger (leaving a wakelock), and then just plug it into my car charger (Type 2) for a few seconds on the way to work to eliminate the wakelock.
3) Mod your charger to bridge pins 2&3. Instructions can be found here.
4) Buy one of these adapters. I have not tested this, but Note users say that it increases the charger current for chargers without pins 2&3 bridged. Theoretically, that means it should be recognized as 2 instead of 6. Someone let me know if you try it and verify effectiveness.
5) Turn on your screen before unplugging the phone. Some users report that this works. I've been unable to get it to work for me. Try it with your charger using my testing steps above if you'd like. (This workaround is courtesy of Note-owner ultravorx)
Why This Happens:
Thanks to pj_rage's research and nighthawkmckenzie's help putting the pieces together. As stated above, the Skyrocket and the Note detect if pins 2&3 are bridged or not. It seems that, for chargers to be Apple certified, they must not bridge pins 2&3. These chargers don't cause a big problem for most phones, but they do for ours. It lowers the mA current and causes a wakelock that persists after the charger is unplugged. The wakelock I usually notice is sdio_al, which seems like it's related to I/O on the SD card. Perhaps detecting a cable connected without pins 2&3 bridged, the phone is preparing for data, then fails to terminate the wakelock.
Here is a really good thread by pj_rage with information on chargers and the Note
My phone takes FOREVER to charge!
Not all chargers are created equal. Some of them enable quick charging, while some of them do not. Plug your charger in, open your Terminal Emulator, and run this command:
cat /sys/class/power_supply/battery/batt_current_adc​
Divide the result by 10 to determine the mA rate of your charger. If the result (after dividing) is close to 1000, quick charging is enabled. If the result is close to 5000, quick charging does not work with your charger.
Wakelocks That Destroy Your Battery Life
If you're not familiar with wakelocks, they're basically processes that run on your phone that prevent it from going into deep sleep. Deep sleep is the mode your phone should go into when you're not using it so that it can conserve battery. Some wakelocks are intentional, while others can be the result of rogue apps or system processes.
For an excellent and thorough guide to Wakelocks and the Skyrocket, check out this thread started by T.J. Bender.
To effectively find your wakelocks, you'll need BetterBatteryStats. It's free to us XDA users. You can get it in this thread. Read that OP for more information about wakelocks.
AudioOut_1 - Hat tip to T.J. Bender's post in this thread for information on AudioOut_1.
Settings -> Sound
Turn keytone, touch sounds, screen lock sound and vibrate on screen tap off.​
sdio_al - This is the wakelock created by your charger, detailed above in this OP.
Clean Out the Bloat
Some of the bloatware and unnecessary apps on our phones can drain battery. Here is a good thread by Earthdog that is stickied in the Themes and Apps forum that tells you what apps are safe to freeze or uninstall. I really recommend you freeze the apps in Titanium Backup and run for a few days before you uninstall. This way you won’t accidentally uninstall something your phone needs to remain stable.
We’re Gonna Need a Bigger Battery
Many Skyrocket owners (myself included) have discovered that the Verizon Galaxy Nexus extended battery works pretty well in the Skyrocket. The Skyrocket’s battery is 1850mAh, while the Nexus extended battery is 2100mAh.
Here’s the thread discussing the battery.
It costs less than $25 at a Verizon store and will add over 10% to your battery capacity. The battery is also made by Samsung and has built in NFC, just like our stock battery.
Some people report filing down the battery so that it will fit in their Skyrocket. I followed the advice of user stevenlong and took the sticker off of the outside of my extended battery. Picture of his battery is here. After this modification, it fits almost perfect. The slight bulge is not noticeable unless you’re looking for it (that’s what she said).
The Stock ROM Sucks
If you’re still unrooted and on stock Gingerbread, I feel sorry for you. What the heck are you doing on this forum if you’re scared to flash a new ROM?
This guide would be way too long if I tried to explain the battery improvements you might see by stepping up to the Stock ICS leak. You’ll probably see even more improvement if you flash one of the many custom ROMs in the Development section.
If you’re dedicated to getting the most out of your phone, spend a weekend reading the ever-loving sh*t out of the stickies in the Development forum. Only after you have read those threads and feel like you have a good understanding, backup your phone and flash a new ROM on it. As long as you’ve backed up properly, you can flash between several ROMs and choose the one that works best for you.
If you have any questions about the ROM you’re trying to flash, ask in the Q&A forum. Don’t start out by asking in the ROM’s threads, unless you’re POSITIVE that the question has not already been answered in the thread or the stickies. You did search first, right?
I can only speak to my own experience, but SKY ICS by seanzscreams has been AMAZING for battery life. I’ve really wanted to try some of the other ROMs, because they look good as well, but SKY ICS has been so good that it’s hard to think of using anything else. Try them all and see which one you like the best. Don't forget to donate a few bucks through the donate button for your favorite ROM's developer!

That guide seems to cover Wifi and BT drain issues with the GS2. I'm not sure how similar our Wifi and BT is to theirs. Our phone hardware is closer to the T-Mobile GS2 hardware than the AT&T.
In my experience, our phone and the AT&T Note have the charger issue. I just tested my wife's AT&T GS2 and it does not have the problem. My problem charger that gives me a wakelock (and is reported as type 6) does not give her a wakelock and is reported as charger type 2.

I'm editing the OP as I discover more and more information and perform various tests today.
I think I've discovered that the wakelock is ALWAYS caused by using an iPhone certified charger (or one that the Skyrocket thinks is iPhone certified). To be certified for iPhone, the charger must include a special circuit that identifies it as such.
I also created a Tasker profile to easily test your charger. The profile reports your charger type when you plug it in and creates a notification if your charger will cause a wakelock.
I would really appreciate if some people can test these theories out. In my experience, chargers that are reported as type 6 ALWAYS create the wakelock. Any reported as 1 or 2 do not.
ALSO: I've always used Stock and Sky ICS. Can someone on an AOSP-based ROM check a known iPhone charger to see if it reports type 2 or 6? This can help us determine if this problem only exists in the Samsung-based ROMs.

Very good info, I checked a couple of my chargers and they were working properly. Thanx
Edit..
I just checked my car charger, bought it at [email protected] when I got my skyrocket. On the attached charging cable it reads 6 in term. Emulator, and if I plug a cable into the USB connection it reads 2.

I am running CM9 nightly 7/7 with Instigatorx kernel, and I just tested the following chargers with the same cable:
Stock Samsung Skyrocket
Stock Motorola RAZR
Stock Palm Pre
Stock 1st gen iPad
All but the iPad report as 2, the iPad reports as 6.
Also, I tried your Tasker profile but it says it can't find /mnt/emmc/chargetype.txt

Thanks for testing.
I also flashed aokp earlier and charger behavior is the same. I wonder if this means it's a hardware problem, not software.
Chargetype.txt should be created in /mnt/sdcard/. I'll have to look as to why it works different for you. You can try changing the path for the read task in the meantime.

No worries, I just manually cat'ted the file. So far I haven't seen the charger wake lock recently on my setup, but I'm still investigating. I am seeing a lot of 'deleted_wake_locks', which may be related to my tasker profile that turns off Wifi and BT during the day.

You're not seeing the wakelock after using your iPad charger? In my experience, plugging in to a type 6 charger immediately eliminates the wakelock, even without restarting the phone. The wakelock seems tied to the last charger you used before unplugging.

Thank you very much for this useful post. I sometimes charge my phone using my usb port on my MacBook at home (it's a work computer--I hate Macs), and I wonder if using that port is causing a wakelock issue for me. I charge it on that and then leave my phone off the charger at night, and when I wake up my battery is usually depleted by 15% minimum by morning (running CM9 nightlies currently).
I'll test it out tonight and report back (if I remember to...which I should...lol).

A 15% drain over an 8 hour period of no use seems normal to me if you have accounts syncing. If you had the wakelock, it would be more like 50-80% drain over that same time.
Your MacBook should report charger type 1 (USB charging), but please let me know if it causes the wakelock (using the CPU Spy method).

I've been using an app called Juice Defender, it's a pretty nice app that will turn off your radios while your phone is in standby mode. I can set my phone on my night stand when I go to sleep and leave it for 8 hours and get anywhere between a 7-11% percent drain. There is three levels of the app (free, pro, and ultimate)
sorry I can't link it cause of the 10 post rule
Just my two cents...

A lot of people use Juice Defender, but the app is very polarizing. Some people claim it's made their battery last forever, while others say it's the same or worse with JD. I used it briefly on my Nexus One and didn't notice a difference. I didn't include it because of the controversy surrounding its effectiveness.
I'll look around and see if anyone has a really good thread explaining its worth and link it in my OP.

My issues with the SR battery have been around the syncing that happens in the background. I finally got my work email down to syncing once and hour and gmail to once every 2 hours. Obviously this varies per person but I think how often the phone sync's is Androids worst enemy. With Juice Defender at least you have somewhat "universal" control over the radio's and when they connect when YOU want them to.
Whether or not you get better battery is in fact subjective to the user.

As far as I understand push email, you shouldn't see much, if any, battery improvement by delaying gmail because it's pushed, not polled. Increasing polling intervals on Exchange email will help, though.
And you're right, the biggest factor in battery life is how people use their phones. The thing I hope to accomplish with this thread is to eliminate the problems that ruin battery life regardless of how someone uses their Skyrocket.

My charger was recognizing as 2 (AC fast charge) but I switched to OEM just to see and it does indeed seem to be idling much better and charging faster. Go figure.
I do suspect this is partly a software issue, but if using the OEM charger works, it works. Good thread.

Thanks for the good info! I try to monitor my usage as much as possible and once I root my phone it will be a lot more flexible, but some new stuff in here I'm gonna try out as well.

Thank you so much for putting this together. I wrote a couple of scripts in ROM Manager to test all of my chargers, and the two Griffin dual-USB car lighter chargers I have both return a 6... After reading this thread, it's not surprising because Griffin is in bed with Apple, and pins 2 and 3 must be open to receive Apple certification. My bad, but I like the Griffin products, and think they are robust and designed well. I've used them with my iPods all along...
I unplugged my Skyrocket the other day when I went to play golf, and used my Golf Logix GPS app. I had a full charge when I started, but I noticed the charge dropping rapidly as I played, even though I kept turning the screen of constantly. By the end of a full round (18 holes), my phone was down to 14%! I figured out was the golf app and uninstalled it, but afterwards, when I checked in CPU Spy, I found that my phone never slept the whole time, even with the screen off...
Turns out, out must be the charger in my car. It's currently cracked open, awaiting my soldering iron and my 1 year old girl's next nap
Thanks again!

Is Juice Defender worth it? With AOKP and many other custom ROMs you get toggles for data/wifi/brightness; shouldn't manually regulating their on/off state be just as efficient (if not more) than automated control? Or am I missing some features that Juice Defender carries

It's a simplicity thing for me. Yes, I could flash a custom ROM and configure everything manually to max my battery savings. Or, I could root the phone, freeze bloatware, and set JD up so that it handles all that for me. I'd probably have somewhat longer battery life doing it the first way (or significantly longer, depending on the ROM), but my battery life with JD is fine for my purposes, so why mess with flashing a custom ROM, the ever-present brick possibility and resetting the flash counter later when I can just root it and forget it?

[Q] Nexus 5 won't rapid charge without maintenance

I'm not too sure how to go about this, but when I try to charge my nexus 5, regardless of the cable or charger i use, it won't charge faster than 1a unless I blow into the micro USB port hard, and I'm not sure if it's dust, because if I unplug it and plug it back in again it will go back down to 1a charging, when i blow into it, it can charge as high as 1700mAh...
Sorry for the noob question, it's my first post.

What are you using to determine the mAh?

He's just going through throttling which is normal. My phone does the same when battery is higher than 80%. My phone charges at 1.7A from 0-80% then 1A to 90%, then 0.6A to 100%. It's all pre dictated by the onboard battery chip

Yeah true, I find the estimation by current widget to be alright for general current usage when comparing chargers. As long as the battery doesn't take several hours to charge, there's no need to be concerned

It was below 80%, and i realize that current estimates aren't 100% accurate but I don't think they would be 600mah different to the original...
I'm using battery monitor widget, I'll post screenshots when my battery drops to about 70%.
I'm not sure if my micro USB port is faulty or maybe it's just dusty, even though it doesn't look dusty, does anyone else have this same issue?

I'm using battery monitor widget, but it shouldn't vary so much just by blowing into the charging port, should it?

Haha, which fittingly has been described by Nintendo to be a placebo effect. If you just took the cartridge out and placed it back in, apparently that had the same chance of working.
I think the same can be said for this situation.
OP, mA current as reported by Android jumps all over the place. I could take a screenshot of it showing 1600mA, 1000mA and 600mA all within 20 seconds of each other. The only thing that you can do to try and prove this is happening (which I seriously doubt) is to use a log to plot the charging level over time. Even then the results could be skewed by whatever the phone happens to be doing during that time.

No that's not it, it does junp a little but never that much for me, it might be a problem with your charger if you're getting that...
Changed the rom and kernel and the problem was solved, i still can't explain it but meh, I'm happy with it now, if only I could do something about battery life now...
You can only do so much with 2300mah in such a high powered device...

This was with the stock 1.2A charger. It's actually just my phone's usage constantly changing that causes the spikes, if logs were able to update more than once per second it would be jumping even more as I'm able to see with manual refresh. This happens during charging, full load and idle situations but your issue might have had something to do with the USB fast charge settings in certain ROMs.
I find the 2300mAh battery can be pushed surprisingly far, depending on your usage. If you're willing to sacrifice certain settings it can make things easier. This is on stock and unrooted, 20% brightness. I disabled Locations, Auto Syncs only allowed periodically at preset times, and used apps that are fairly battery efficient.
That was mostly WiFi, but this was with more mobile usage. Two work days on a weak 3G signal, 40% brightness using mostly Hangouts, Feedly, and 2 hours of video. Check out the [Battery Life Help] thread for more tips.

That's pretty impressive, i usually get about 3 hours SoT, with a bit under an hour phone calls usually and occasional snapchat, usually just internet browsing, underclocked to 1.7 and i almost half an hour SoT improvement without any loss to performance, cause i don't use my phone for gaming...

Relation between charging at night and performance/battery

Hi everyone !
I haven't seen this info anywhere on XDA, at least on this forum, but i think everyone should know this.
Not trying to take credit in any way, because OP made a terrific job at researching and testing, just wanna spread the knowledge.
Basically : Charging your phone at night or leaving it charging even while at 100% for a few hours will have a big impact on how it behaves and how your battery holds up.
Quick explaination : Since Nougat, you don't get the App Optimization screen anymore on the first boot.
That's because Google has delayed it, and it triggers only in specific conditions : When the device is idle, fully charged, and still plugged in.
This optimzation allows to build the ART cache, which speeds up the system and apps, saving CPU power because it avoids using the JIT (Just In Time) compiler, thus, saving battery juice.
This also means wiping cache isn't going to help with your battery life, quite the opposite.
You'll see he made a test with other users, and the results are quite clear.
Here is a link to the post with detailled explaination and testing, thanks a lot to anupritaisno1 for all this info :
https://forums.oneplus.com/threads/...-and-battery-calibration-myths-busted.993896/
Forced the building through "cmd package bg-dexopt job" on my own OP6 running Pixel Experience, took like 15mn. SOT improved quite a lot.

Interesting read, thanks

What if you charge it at night while the phone is OFF?

If the phone is OFF it can't trigger the optimization task, this won't be beneficial.
In the article he actually made a test about this, you should read it !

Interesting, but... who claimed that clearing the cache helps with the *battery*?
Also, what happened to the old adage "never leave your phone plugged in" because it causes battery wear?

A lot of people claim this, that you should clear the cache after an update, without clear reason why. At least we have a reason not to.
And this old adage is indeed old, like the "Fully discharge it for calibration". We're not in 2002 anymore. Modern technology had the nice idea to remember to stop the charge, and use Lithium batteries haha !
Leaving it plugged at 100% is not causing any wear. The post mentions a response from an electrical engineer, saying the battery is in fact on stand by and the phone is running off the charger only.

That's just one way to read it. Leaving it plugged in does not, indeed, mean that it keeps trying to charge. But once it goes down, it will charge up again. Also, supposedly, the fuller the battery is when charging, the higher the temperature and hence, the wear. Cannot attest to that, that's just how the argument goes.

Yes, but that's irrelevant. Totally different issue, I was not talking about calibration.

Indeed. But from the looks of it, and what i've read in other places, it waits for it to drop a bit. If the battery is not used, it won't fall to 99% in a night, and won't be charged again until you unplug it. Kinda like when your phone is off. It's gonna be a long time before the battery goes down on it's own.

Interesting, gotta try it.
Still, does the <50, >70% not apply in terms of battery wear? I mean, even for straight-forward charges?

I'd say yes, it still applies. It's a different topic ! Everithing said here is related to software and charging control, when this is more related to battery chemistry. But you're right, it's still true.
To sum it up :
- Charging above 70 or 80% and discharging under 30% (Thoses are the values i read about) is indeed not the best thing for your battery health on the long term.
- BUT, the superior battery life your phone will get with these app optimizations easily counter-balances it. If the phones lasts twice longer, it means 2 times less chaging cycles required, when you think about it (Ofc not accurate, but you see what i mean)
Best thing you can do, if you really want to get the best of both worlds, is staying in between those ideal values, and triggering the optimization manually via the Linux Terminal Emulator
Although, i don't think i'm not personally going to bother, i'll just charge my phone, use it, and charge it again in the evening.
Two days after triggering dexopt manually, without flashing or changing anything, using the phone the same way, i went from 16h idle/2h SOT at the end of the day with 50% remaining to 20h idle/2h15 of SOT with 70% remaining, that's quite a drastic improvement.

Ooh can you share more?I tried googling about triggering the optimization but came up empty...
Yes, that's logic in that, if optimization is so dramatic!
PS I meant 80, not 70, just as you mentioned.

Yes, it's hard to get an info about this, wierd.
Run any terminal app on you phone, type "su" to ask for root permission, then enter "cmd package bg-dexopt-job" (without quotes).
It will run for a certain amount of time (between 10mn and more than an hour, depending of the number of apps you have installed).
When you get the shell back (A line appears under the last one to enter another command), it means it's complete.
If you wanna be sure, run it again, it will finish very fast, because the cache will be up to date (It still checks it, so it's not an instant completion).
Do it plugged in the charger, but with like 30% charge, maybe on USB so it doesn't get to 100% too fast, to avoid the awkward situation where it overlaps with the actual automatic background process doing the same thing haha
The phone can heat up a bit because the CPU is working quite a bit.
You can also run the command through an ADB shell on a PC, if you're not rooted.
Or just leave it charging during a night for once, works too
Best way seems to let if charge for the night regularly though (Quote from the OP) :
"I just say overnight because the device being idle is a condition for the optimisation to begin
Also the optimisation is profile guided. If you were to AOT compile your entire base system it would take 4-5 GB off your storage and that is just the base system we haven't even considered the apps you'll install. Since optimisation generates huge optimisation files it is more sensible to only compile what is slow for JIT to do at runtime. This might seem weird but it takes the cache size down to less than 1 GB on most devices
In other words every time you use your phone the runtime sees what is slow and queues it up for optimisation the next time the condition is satisfied"

Wow. This should be pinned somewhere!
I'll do it in the terminal just for fun, but will also leave it (for my first time ever) overnight too.
Thanks, man!

I think everyone should read this yes, even if it's just for the sake of knowing how things really work.
And i can confirm again, my battery life is so much better ...
A few days ago, going to work, listenting to Spotify on my motorcycle for 20mn, and checking my mails for 2m got me to 96% battery.
Yesterday, and today, same routine, an an hour after that i'm still at 100% ... That's very impressive.

Really interesting.
Sadly the command does nothing on my device.

Are you sure ? It doesn't display anything, that's true. But you'll know it's over when the shell returns.
Or you can juste leave your phone plugged for a night or two, same result.

My battery goes from 100% to ~97% within minutes without using it after unplugging the phone from the charger when charging overnight.
Why is that and how can I get rid of it? It occurs since a few days on custom rom as well as on oos now again.

[Discussion] Battery Health

Hi guys,
as we are approaching nearly 1.5 years since the Pixel 5 was released, I am curious what everyone's Battery Health is.
You can use Accubattery.
BatteryGuru also has it included in their app.
It will take a few charges to get an accurate reading.
I take pretty good care of my battery, by never going below 20% and only gone about 80% maybe 10 times.
I just got Accubattery on my device so I will update where I am in a little bit.

Well since I feel itt'll take a good 4-5 charges before any type of "accurate" measurement is shown, I decided to do a full charge and I'm very happy, I feel like this is at least 90% the capacity still. Right now BatteryGuru is showing 70% but I expect it to *hopefully* go up, since accubattery is showing 85%, but this is only after 1 charge.
Running Android 11 crDroid v7.15

I did 1 full charge (35% => 100%) with AccuBattery, says my battery health is 93% (3 718 mAh / 4 000).
Not bad I guess, for a 16 month old phone which I used to charge regardless to "efficiency rules".
I used stock rom, and rooted couple of months ago. And only recently switched to lineageos 18.1 and elementalx kernel so I can't tell if there's a difference.
I'll take a look at crDroid, but I can't help installing some google stock apps - force of habits.
If I see any significative change after some charging cycles I'll give an update.
Btw are you using a custom kernel?

Thanks for posting my friend! That's a great starting point, I hope that it only gets better for you!
I'll upload images from what accubattery and batteryguru are currently showing, now that I have a few charges completed. I hope to see a higher health.. but it could always be worse. I remember my htc 10 bring at like 70% at this point in it's ownership.. though Android wasn't as up-to-date with battery adaptivities.
I used to use ElementalX but since lack of updates for Android 11 I've been pretty happy with crDroid stock kernel. (Though I have used the last update that was out and it ran quite nicely before I moved fully to crDroid. So I may give it a go and see what type of battery I am getting compared to crDroid stock).
CrDroid also comes with PixelGapps installed, which I personally love. So you'll get Pixel launcher, Camera and other Google apps/goodies .

I am not a very patient man, and a few minutes reading about this rom convinced me to try it asap !
Love it so far, I really like the stock experience with easy tweaks possibilities - I also already shared my gratitude and first issues in the main thread
I'll keep stock kernel for a few weeks and share accubattery and batteryguru screenshots here, before giving a try to elementalx kernel and see if there's a difference

This is all stock with root and some modules installed. I received my device in November of the year it was released

Just kept my battery charged between 80% to 20%

90% here. Have the phone almost since launch and accubattery since then. Don't follow the 80% rule too much. I use to follow it religiously but then read a comment somewhere that by following it, you are at 80% health effectively so... it made sense.

So after few weeks I'm 90% on Accubattery and 85% on Batteryguru. I did noticed the stats were pulled down when I charged only to 80%, so I would tend to agree...

I installed ElementalX a couple of days ago, I've let it just as it is out of the box, no personnal settings. It seems to be very efficient with battery usage but maybe too much because I don't receive whatsapp calling notifications anymore, only "missed call" once it's too late... gonna take a look on the official topic to check it out.

I am at 90% myself actually, and noticed it actually went up from 88% to 90% when I charged it over 80% to 85%.
So maybe with all the new changes and upgrades to batteries, etc, charging to 100% is just fine?
I think it is the charging overnight for more than 8 hours can possibly be harmful.
I think I'll start charging to 90%.
Maybe try adding whatapp to battery optimization, is you haven't already to see if you start getting the notifications.

Already tried that but thanks for suggestion
About battery, I'm far from being an expert but I think it's still good to charge up to a lower lever eg. 80-90%, in order to preserve battery health and loose less capacity at each cycle. However, in order to properly measure the battery's performance, you'll have to give it a full charge or the stats will be inaccurate, as @ribogushter mentionned.
I would suggest, wipe your Accubattery and/or Batteryguru stats and give your phone a full charge from 20 to 100% and see if it impacts your health score

Darn sorry, wish I knew what else for you to try.
I think I will keep my stats in accubattery as it gets better with time, but I will charge it to 100% and see if it drops, goes up, or just stays the same at 90% health.
Edit: both accubattery and battery guru dropped a bit after charging to 100%.. down from 90% to 88% accubattery, and 89% to 86% battery guru.
I think I will probably do 90% from here-after though, I still think charging all the way to 100% all the time isn't the best, but I really don't know anymore!
I'd like to read more about getting the only 80%, I mean it's just common sense that you get actually only 60% if you run from 80%-20%, but that is charge capacity, not battery health capacity.
I do wish Google/Android had some documentation on this. Even cApple at least has a battery capacity built into its settings, and I saw they have a setting that tells if say the screen was replaced was it done using official cApple products, very good idea actually.
Also how has ElementalX been running?
I decided to flash it and see how it compares to the stock kernel in crDroid_v7.17 (Android 11)
I always loved it when I used it, but it is a little out-dated, (over a year now) but I think it's still fine.
Proton kernel is also really good.

As you said, we probably never will have a 100% effective method to quantify battery health until it's native to Android ¯\_(ツ)_/¯

Really smooth, I'm not experiencing any lags or freeze, or any problem so far and battery life seems to have improved. As a pure rookie, I don't understand what would make a given kernel different or better than the other, so I tried the one that seemed to be the most popular but I noticed only afterward that it hadn't been updated for a while and that the developer is focusing on his apps (he mentioned it on some thread).
Proton kernel's latest update is also almost 1y old, I'll stick with ElementalX until next update or give a try to CleanSlate which seems to be the most active.
Btw, I guess you're using ACC? If so, which charging switch are you using?

Best way to measure your battery is to charge it with an USB tester such as UM24 or UM25 . You can see how much mAH your battery can absorb and calculate the health . Phone needs to be turned off and charged with a regular charger, not fast-charger .
I'm looking for a good benchmark for the battery , i tried Geekbench4 , PC Mark ..do you any other good ones ?

Not that I think it helps I am always on my PC and just charge through the usb-c.
charges pretty fast too, like 45 min.
I may invest into UM24 orUM 25, thanks @arcadekidflo

If you only use usb-c to usb-c you can get TC-66c , from the same company . If you also use regular chargers you can get UM-25c .

I accidentally charged to 100% again, and health went up in accubattery.
Maybe I will start fully charging..
Oh yea. One thing that helped for me for late notifications is to turn off "Adaptive Notifications"
-- It's been working for me.
some ROMs (such as crDroid) it turns it back back on after every reboot.
I just make a shortcut on my homescreen using Activity Launcher

Many thanks my friend! Very much appreciated.

Mine looks like it's around 94% - ordered it on release day, so about 1.5 years old now.
I've not followed the 20% - 80% rule, most of the time just letting the phone charge fully over night.
Maybe the 20% - 80% doesn't really make any difference?

IMO it's pretty silly to only use a portion of your battery's indicated capacity. The nature of lithium ion batteries is such that both over and undercharging can cause damage, so manufacturers don't actually use 100%, or even 80%, of their full voltage potential. The battery circuitry itself, as well as the phone's power monitor, do a sufficient job of limiting charge and discharge, so its really not necessary to do it yourself. Use your phone as you normally would, but be aware that keeping it charged all the time may reduce battery life.

Check for battery drain in my OP7 Pro

Hi everyone!!
I'd like to get some advice about my issue that I've been having for a while...
My battery drain is what you may see in my attachments. Please tell me some good advice to reduce this drain or whether it is normal functioning either...
In conclusion, I'd like to know if it might be convenient to replace the battery and, furthermore, whether there are larger batteries with more autonomy.
My phone is 2 years and half old but to be honest I use it intensively with its battery-case (manufacturer: Newdery).
Thanks!!!

Sorry for late reply, just saw this.
You get 6 hours of battery life with 14% screen on time? That doesn't sound to correct.
My suggestion would be to install the app: AccuBattery. I swear by it - it is very good I think. It will watch your apps much better than the stock android battery monitor. It will also tell you your battery health, the mAh left out of the total of 4000. If you have a very low amount left (capacity wise) then you may want to get a new battery. But make sure to do several charges before taking it as accurate. Use the app for several days, even the little "notes" in the app will tell you this - it's to "acclimate" to your use and give you more accurate statistics.
Hopefully this helps - 6 hours is definitely not good.

Hi!!
Thank you very much for your reply!
I forgot it but I already had Accubattery installed on my phone.
In fact, in attachment you have the battery wear data from April 2021 till now..
I hope that I shared you useful data to analyse the issue.
What do you think? What should I take from the app?
I thought that the new Android version 11 is the cause of battery drain as another phone (Xiaomi Redmi Note 10) suffers from it after the upgrade to Android 11..

No prob
Could you take an [extended/full] screenshot of the "Discharge" tab? That will show more info about which app is draining more. Also those numbers change I believe on every charge so you'd have to just keep an eye on which app is always at the top of the section under "Foreground App Battery Usage > Battery Usage" section. Hopefully it isn't just "system" or something, hopefully it is an app that you can remove/freeze.
And what does it say for Battery Capacity above the "Battery Wear" chart?
And speaking of the wear chart, you'll want to stop charging all the way to 100%, it looks like you're putting over 1 cycle of wear on the battery very often which will degrade the battery quicker. The 'Charging" tab explains this even allowing you to set a reminder to unplug at a certain charge level (it tells you the higher you charge the more wear you put on the battery - unfortunately that's how batteries work).

Hi, thank you for your reply!!
I'm sorry for my late replies..
In the attachments you have what you asked me.
It seems that Facebook drains the battery a lot despite the fact that I don't use it much.
The battery wear seems to be almost one fifth of total capacity for a capacity of about 3200mhA.
I'd like to have something better...
I have set at 83% the alert to reduce the wear of the battery but I wonder how it could work fine when the phone is turned off..

No problem
So, I'm not exactly sure how you use your phone but it looks like the screen-on at 23%/hr looks pretty bad but then also it says combined time was 102 hours? I believe that means how long it's been off the charger. If that's the case you can't get any better battery life than that, that is really really good.
You mention facebook doing a lot of draining. Try researching a good app freezing option on the app store. I only did a quick search but this one came up: https://play.google.com/store/apps/details?id=com.catchingnow.icebox but read the reviews (I did a quick scan and it looks like it might work as intended) and look around maybe there is a better one. But the point of this is, to freeze any apps in that list (the accubattery foreground apps) you barely use and it will prevent them from running in the background. This will definitely give you better battery life.
And I don't see the deep sleep statistic, is that around 90hrs along with the screen off time? It should be more than the screen off time at least, because if it is then it is deep sleeping correctly (no rouge apps causing it to not deep sleep), but if it's less than the screen off time, then something (maybe facebook) is keeping the phone awake even with the screen off, causing extra battery drain.
And 83% charge is pretty good, maybe even 75% might be better, I think from 0 to 75 it's like .3 or .4 wear but it's like with these batteries once you start going over 75% it jumps in wear dramatically. And if the phone is off (turned off completely you mean?) then the battery won't gain any wear because it won't be in use at all.

And 83% charge is pretty good, maybe even 75% might be better, I think from 0 to 75 it's like .3 or .4 wear but it's like with these batteries once you start going over 75% it jumps in wear dramatically. And if the phone is off (turned off completely you mean?) then the battery won't gain any wear because it won't be in use at all.

I noticed that I didn't make all the screenshots, but now I've just done them with regards to this new discharge cycle and you have the deep sleep statistics for a better analysis - they are in attachments.
I asked here for a longer battery lasting and instead I set it as 75% as the maximum percentage value of charge that reduces my autonomy but saves the battery.
However, yesterday I noticed that the charging wasn't deactivated when the phone reached 80% of charge (is the value that was set yesterday). Oughtn't Accubattery deactivate the charging?
The statistics you mentioned in your previous post appear to me a bit awkward even though they are related to many sessions in the last 7 days.
I use my phone with my phone case-battery (Newdery manufacturer) and until few months ago it could charge the phone up to about 80 % when I couldn't charge my phone through its charger. I need the charge to last a day, almost 20 hrs…
I noticed that the phone started to wear - the last few months - when I noticed that I couldn't have the phone working till the late evening and I tried to charge it fully before I left my house...
However, it is clear what I need for my use and habits, thus, new reliable battery-case suggestions would be a good hint for me...
In the end, I don't know what to do about apps that manage the apps freezing because I don't know how Android allows it and if it is worth it..
