[Q] Battery Drain issue, please help

Hello,
I'm currently experiencing an unexplained battery drainage issue and need some ideas from you all! I used to get a battery drain from the phone while it was asleep and connected to my wifi of -10 to -14Ma, where as I now get -76Ma! I'm using "Current Widget" from the market to monitor battery usage which is logged to a file. I have no idea where the additional % is coming from and after exhaustive testing over the last day I'm beginning to go out of my mind here... The phone is consuming too much battery while idle and therefore running flat far too quickly.
I can't quite determine when this started to happen. I'm running LBC v0.5.4 and have been for ages, I upgraded to the latest radio 06.02.03_M although I've tried reverting radios to most of the older ones and can't seem to loose the problem. I've completely reset the device, using the WIPE script (format commands) and installed fresh LBC v0.5.3 and v0.5.4, after the initial install I get the minimal drain (-10Ma) to start with but after the first device reboot its back up -76Ma, this happens both with & without a google accounts configured.
I have no additional applications installed from the market and am installing only current widget from its apk. AUTO-SYNC is off. I've even tried multiple full resets, re-flashes of the ROM, differing kernels, multiple Radios and setup using a different google account (my wifes) and the same thing STILL happens.
It can't be the router related as my wife phone a brand new DESIRE S (still running STOCK) is getting -16Ma from the same router, which I have rebooted. It can't be current widget as I'm running the same apk that my wife is and she isn't getting the problem, plus I've run it for months now and not seen this drain!
I'm considering going back to STOCK! which can't be good. Please help....any ideas and/or suggestions welcome.....(except use my wifes phone!) I must be missing something?
If you can't think of anything that I'm missing, could you at least state the ROM & RADIO version that you're using and the battery consumption that you get in a similar state.

have you tried deleting the file battery_history.txt on your SD card?

I only have a currentwidget.log file on the SD card that's produced by the Current Widget application and I've tried removing that a couple of times with no effect.
What produces battery_history.txt? isn't that another battery consumption application?

It's the Battery Monitor Widget. Try that and report the results.

Opps I thought you were refering to battery monitor widget
Try battery monitor widget like shrome suggested
Other than the reading how is the battery life doing,it is possible that the reported reading is incorrect ,if the reading is right your device should be out of battery very fast

No problem...
The battery life unfortunately does seem to be reduced. I have always had that widget on my main home screen so notice its reading whenever I'm operating the device for months now and its normally accurate which is why I spotted the change.
Although I'll be honest since I spotted the change in the reading I've been constantly flashing, wiping, restoring etc which are all heavy operations on the battery life so its really difficult to tell.
Next time the battery hits 100% charged I'll also re-calibrate.
EDIT: Have wiped battery stats from recovery
EDIT2: Have switched and am now testing with battery monitor widget, will report back

Have again fully wiped, reset and re-flashed LBC v0.5.3. I configured no accounts and turned off auto sync. Flashed v0.5.4 update and am running with the latest RADIO (20.28I.30.085AU_3805.06.02.03)
No applications installed except Battery Monitor Widget. No screens contain any widgets apart from the clock.
My device is clocking battery consumption figures of -36mA to 100mA...
Yet my wife's new (STOCK 1.30)) with 03.02.11 radio is clocking just -7mA!

My device isn't particularly warm.
Although good call on swapping Battery and SIM I'm doing that now, just one at a time in the hope that it is one of these then I'm able to identify which one
EDIT: rather than change too many things at once I'll also try a different SD card in mine after these initial tests.

OK, this is downright weird. The issue is probably in the kernel, not Radio. Try switching kernels, go to Unity V2.
EDIT: This may be a hardware issue. I think i read your wife has a desire s. Try switching batteries.

LBC mod 5.4 comes with unity v2 kernel as default
& also it can't be a software problem as he has been using the device with the same setup before without a problem

Correct, I tried switching kernels back to stock earlier and saw no difference.
Swapped SIMs and saw no noticeable difference the new device was still clocking incredibly low numbers.....<10mA whereas mine (with her SIM) still clocked ~50mA
Swapping batteries now.

what's the reading on your wift's battery?

If all else fails, try switching ROMs altogether. Go to virtuous unity. Aosp roms have battery drain, so you won't have any luck on those. Maybe an upcoming update of lbc mod fixes this issue.

mind trying and tell us your reading?my friend who's on hd2 android has reading around 1-4 mA..

1-4 mAH ?!?!?!?! This is freakin impossible on desire s. 7-10 is normal. I think he posted in the first post.
Edit: ok, this is a shot in the dark. My friend on Virtuous ha similar readings, so i was following this closely. Turns out, he was checking the widget rather than the file in te sdcard (battery_history.txt) the file shows the stats for when the phone is asleep. Check carefully. The widget will usually show 70-100 mAh, as while checking the widget, the phone is awake.

Was still testing, as I need to collect a few continuous minutes of screen off testing to make it fair.
Although as you mention in the LBC thread. which hopefully shows that this can't be a hardware issue with my device, unless it's from the w-ifi attena itself?
If I swicth off the wi-fi completely on both devices, which I've just done then the drain disappears from my device and it starts clocking ~13mA, although hers is still consistently putting in 7mA.
Now time to try a new SD card in mine, must try that before reverting to stock ROM.

Easy....he said his friend with a HD2, its a known fact that there is a battery drain issue on the DS as if you were to compare its drain to that on the old Desire its over twice the idle.
There are plenty of threads early on covering this issue....although none of them ever identified any reason. Its interesting to see what the CM7 ROM can achieve in this respect.

Newer processor = more battery consumption

Fair call....but unfortunately I'm checking both but only rely on the results from the file.

Is anyone else getting massive battery drain?

Since I upgraded tp 4.0.4 my battery life has been completely terrible (nexus s GSM, stock, latest glados kernel) even though I don't use it the entire day, it drains over half in about 4 hours. Anyone have any idea what I can do to fix this? It was perfectly fine before the update and would last days if I didn't use it, and about 12 hours if I did. Right now it's just unusable.

BetterBatteryStats and/or a fresh install (data/factory reset, format /system, optionally format /boot, install ROM).

Are you using a custom ROM?
I've had the same problem when I was in stock 4.0.3, which is why I decided to root my phone and resort to custom ROM's and kernels. Now my phone is doing ok in the battery department and is also much more snappier and smoother. Oh and most custom ROM's are already using 4.0.4 anyway.
Let's try and be scientific about your problem, here are some things you may want to try out first to improve battery life:
turn off wifi when not in use
turn off automatic syncing if you don't need it
set your network mode to 2G only if you're not using the internet
turn off mobile data when not browsing/using the internet
install the watchdog lite app/widget from the Google Play store so you can monitor rogue apps that are sucking up juice
do not set your screen brightness to AUTO, but manually adjust it when you need to. you can do this either in the settings menu or thru the power control widget
This are the things I can think of off the top of my head. If this doesn't improve your battery life, even just a bit, you may have no choice but to resort to drastic measures....and go to the dark side.
Hope this helps! Cheers!

mine is okay
Batt I think it quite good on 4.0.4. I can get about 23hrs of usage. Some wifi, some 3g (fb, whatsapp, updating apps, email), some music. Stock ICS.

I had this issue after stock 4.0.4 update from 4.0.3.
I found mediaserver using more battery than it should, so I;
1) Copied all files and folders from /sdcard to PC
2) Re-format /sdcard
3) Re-store all files and folders back to /sdcard
Mediaserver process is now minimal and battery is good again

Ok thanks for the suggestions guys, reformatting my phone would be alot of effort on my part due to how much time I spent setting it up so I would like to use that as a last resort.
I installed battery stats but I can't decipher what it's saying so if someone would be as kind to explain? I took screenshots of everything in an album and I would really appreciate it if someone had a look in the album below.

Well for one, you have chunks of bad signal(red bars). That right there can kill a battery quickly. The other stuff you may be better off saving the dump file and posting it as an attachment over at the BBS thread. The guys over there are pretty informative and may be able to give you more stuff to look at to help you out.

The red bars are when I was using the underground, the battery drains just as fast overnight. I will look for that thread, thanks.
Edit: I do not stay on the underground overnight, and I have a good signal in my apartment (you can see it's fine when I arrive)

yep...a weak network signal will drain your battery a lot faster. if you're not using it to text, call or surf, or if you're just going to play games, might as well go airplane mode for a while, or at least until you get above ground where the signal is stronger.

After a good couple of hours not using the phone in a good signal area create a log and post it. Preferably get the hours just after charging.

Ok nevermind just did a reformat new rom etc.

Sorry guys, but after reinstalling I am STILL getting the battery drain issue.. Was a clean install but reinstalled all my old apps and settings. from full to 28% in 5 hours with very little usage.

Please someone take a look!!!

I'll have a good look tomorrow with some suggestions. Had a fair bit on the last couple days with minimal internet access.

What ROM and Kernel are you using right now?
There are a couple of interesting details there but nothing that i can point out that will take you from 100% -> 30% in that time.
Some things to test:
-Turn phone off (noting charge), remove battery, replace battery, leave phone off overnight and turn it on in the morning, again noting the new charge
-Keep data off and see if battery is still draining / Airplane mode
-Uninstall half of your apps and see if it still happens. If not, add half of the apps you uninstalled. If so, uninstall half of the apps you have left, and so on.
-Do a clean install and try for 2 - 3 days, see if it still happens (preferably a stock ROM, preferably from fastboot images)
-Attempt going back to Gingerbread and try for 2 - 3 days (preferably a stock ROM, preferably from fastboot images)
These steps can (and should) be done pretty much in order and will rule out ALOT of possible reasons and give possible solutions some merit. Let me know how this goes.

Using latest stable cyanogenmod + tried glados and netarchy and matrix kernels, all the same result. Will try what you said, also I bought a replacement battery to see if the actual battery is faulty (weird because it used to be fine). As for the airplane mode thing I already tried that, to no avail.
edit: should add that was using stock 4.0.4 before cyanogenmod.

One X Gets Hot without use and battery life tanks

I've been noticing less than stellar battery life ever since I got my One X.
Lately I have noticed that sometimes my One X will get slightly hot under use(around the camera area), and then after I'm done using it, it still hot and my battery drains like crazy.
I turn the screen off, kill all apps, wait 5, 10, 30 minutes, even one hour I have waited, and the phone is still warm!
I don't use any apps that run in the background or have services that use a lot of battery. I've checked logcat, betterbatterystats, Cpu Spy and can't find anything wrong. I've tried different roms and the same thing happens.
The fix is simple. I just power it off and on and the problem goes away for a few hours, but then comes back! When I power it off, the area gets ice cold in less than 3 minutes , which tells me something is going on.
I can't figure out a pattern to trigger it but it seems to happen most when my phone switches to WiFi from LTE or vice versa.
Has anyone noticed this? It's been incredibly frustrating.
-----------------------------------------------------
After months and months the problem has been found and resolved. It was due to an LTE bug that would happen in certain areas(such as subway stations) if you lost all signal and then regained. The phone would get warm and battery would drop significantly, as much as 2% per minute. The drain would not stop until a full restart.
After trying many many roms, and after about a month testing it, this one has the problem fixed. I haven't tested other ROMS and quite frankly it works so well that I didn't bother testing for other ROMs.

I have this problem too. I put mine to sleep, after waking up from an hour nap the darn thing is hot! And of course the battery drained like crazy. Although it's too early to come to a conclusion, but so far it hasn't happened ever since I turned off autosync and wifi every time I take a nap..

Run betterbatterystats and carat, they can all identify various issues.

My phone does not deep sleep at all. Wtf?

I'm having the same problem, carat and bbs aren't helping
Sent from my HTC One X using xda premium

See if there are rouge apps running in the background that are keeping the phone from deep sleeping.

Go to Settings -> Wifi -> Advanced -> Best Wi-Fi Performance and make sure it's unchecked. It's been known to prevent deep sleep. I'm not sure it would cause such a huge drop in life or the heat, but every little bit helps.

Glad to know I'm not the only one experiencing this. I'm an advanced user, I've tried everything, carat, BetterBatteryStats, aLogcat, System Panel, Cpu spy, you name it. The phone is actually deep sleeping.
Also, I've noticed that the radio area gets hot more than the cpu area, so it might be a radio issue? I'm running baseband 0.17.32.09.12_10.86.32.08U .

I'm on 0.17.32.09.12_10.86.32.08L (same as you, except for the L). I noticed that you mentioned that it may be when you're switching between WiFi and LTE, maybe it's continuing to hold on to that LTE connection? Also, where is the radio area in relation to the CPU? I know the CPU is right underneath the camera.

What is the difference between the L and the U? I've never flashed any radios so I guess I'm using the stock one from the 1.85 update.
I actually just assumed it's the radio because I was testing a cpu stress app to see if it would get "locked" in a high frequency thus causing the drain, but the area that got hot was to left of the camera area, and usually when the problem happens I can sense the warmth more to the right, around the LED flash.
I just charged my phone to 100% and it got warm, I unplugged it and waited a few minutes and the phone was still hot. I turned the phone off and in a matter of minutes (Like 4) , the phone was ice cold again. The plot thickens...

I don't know what the difference is. I'm running CleanROM DE so it could be that the L is just the radio from 1.88. I never had this heat issue on 1.73, 82, or 85 though. Just the normal amount that threatens to burn your hand off while playing Angry Birds. Maybe try disabling LTE? (Don't ask me how to do that)

Disabling LTE (By changing the APN settings) , makes my 4G(Non-LTE) connection unstable, for some reason. I experience a ton of data drops , so even if fixes the heat problem, it would create a new one. My data connection is rock solid when using the LTE APN .

I'm running stock 1.85 and the battery is great

I had a similar problem before until I installed CleanROM LE 2.0 (and above) I noticed the problem when I connected to wifi after I had lost signal from my commute every day. BBS didn't really help, and it seemed the problem would compound over time, eventually getting to a point where I was losing 3% battery ever couple of minutes.
After I installed the Lite Edition, the problem hasn't appeared since. Battery life seems to be draining normally and the phone doesn't get hot when not in use. It could be something that was removed from Sense that helped the issue, but I'm honestly not sure.
I do remember that before I switched to the Lite edition I tinkered with some settings, and I noticed that Latitude was set to update my location. I turned it off (it's off by default on the Lite Edition ROM), but I'm not sure if that helped my problem. Maybe try disabling that and see what happens.

There's a thread with flashable versions of all the known radios floating about...There's nothing with a U in it except the Asian radio, but the rest of the baseband version number doesn't match.

He fixed that now so even the Asian version apparently ends with an L. Does that mean I have an unkown baseband? doubtful. I have installed sick sense hox and so far so good. We'll see.

deep sleep and warm back.
I've noticed this, too.
I've woken up in the middle of the night to encounter my screen on and no gain in battery charge with a super warm back.
Last night I plugged it up at 73% and I woke up this morning with 71% and a fry-an-egg-hot back.
Restarting resolves the issue, and this is only the second timein about 1.5 months, but a concerning issue nonetheless.

Blame calendar sync
I had the exact same problem, and I narrowed it down to auto-sync.
In particular, my phone was constantly sync'ing my work calendar (my work place uses Google calendar/mail). I have a lot of recurring (weekly) events on that calendar, and one of those events was modified shortly before the sync started acting crazy.
How I fixed it:
1. Go into Settings > Apps > All
For "Calendar" and "Calendar Storage" apps, press the "Clear Data" button.
2. Removed my work Google account and re-added it.
Obviously, if it's not the sync that's causing the battery drain or you don't have any calendars synced, then this is not going to fix anything. Just thought I'd share my particular case with everyone.

Battery drain issues: last attempt - with screenshos and dumps

Hi guys,
I am hoping someone may notice what's going on with my device... I am at a loss. Attaching all screenshots and dump file from BetterBatteryStats (may need to open in Wordpad for the spacing work).
To summarize, my battery drain is very inconsistent. Some days it lasts a long time, 2-3 hrs of screen time, can stay in standby for over 2 days. And then some days it drains very quickly, like right now - it drops by 3% every time I basically turn on the screen to check e-mail/messages. I think we can all agree that 4 hrs of standby and 15 mins of screen usage should not use 50% of the battery.
I have tried two different units (swapped thinking my battery was faulty), and the issue persists - so I think it has to be something related to my software setup. I am running the AT&T LTE stock phone, 1.85 firmware. I have tried doing the full factory reset (clearing all settings/apps/storage), and cycling the battery.
Some folks have mentioned that my drain seems to begin when I hit an area with low/no signal (I take the subway to work in the morning), and then persists - as if something is trying to sync/connect somewhere, but can't... so it keeps looping and draining the battery.
My autosync is only on for Gmail, Google calendar (not contacts), and Weather (every 2 hrs only). Phone is not overly hot, battery is at 86 degrees right now. My brightness is at 40%.
If someone has any ideas, please share - I am at a loss, I don't know what to do... but battery life has got to be better than this, at least in terms of consistency.
Thanks so much.

Little to no signal is a battery killer.

Right, but the phone drains like crazy after the signal is regained. It doesn't drain much while there is no signal. Besides, what are people supposed to do when they lose signal? Restart the phone afterwards or lose all battery?
Also, some days it works just fine (and I still take subway to work on those days and lose signal) - so not consistent. I don't think it's simply the fact that no signal kills my battery in this case.

But OP is getting huge drops in the battery level when network signal is green (full signal strength); and also screen mostly off. Which is very odd . . .

Sounds like there are other folks experiencing this issue, related to signal drop in LTE (riding a subway, etc.):

To summarize, my battery drain is very inconsistent. Some days it lasts a long time, 2-3 hrs of screen time, can stay in standby for over 2 days. And then some days it drains very quickly, like right now - it drops by 3% every time I basically turn on the screen to check e-mail/messages. I think we can all agree that 4 hrs of standby and 15 mins of screen usage should not use 50% of the battery.
I have tried two different units (swapped thinking my battery was faulty), and the issue persists - so I think it has to be something related to my software setup. I am running the AT&T LTE stock phone, 1.85 firmware. I have tried doing the full factory reset (clearing all settings/apps/storage), and cycling the battery.
Some folks have mentioned that my drain seems to begin when I hit an area with low/no signal (I take the subway to work in the morning), and then persists - as if something is trying to sync/connect somewhere, but can't... so it keeps looping and draining the battery.
My autosync is only on for Gmail, Google calendar (not contacts), and Weather (every 2 hrs only). Phone is not overly hot, battery is at 86 degrees right now. My brightness is at 40%.
If someone has any ideas, please share - I am at a loss, I don't know what to do... but battery life has got to be better than this, at least in terms of consistency.
Thanks so much.

Step 1: Remove sense.
Step 2: Proceed to experience the best battery life I have ever seen on an Android device.
If you do not want to remove sense then you need to take a very close look at your apps because something in the apps is responsible. I personally think its HTC sync or some other rediculous service that comes preinstalled on the phone. Something is trying to sync or communicate and is hanging.
Like I said, get rid of sense and save yourself the hassle. Nova Prime + AOKP = the best mobile operating system known to man.

I am a bit new when it comes to Android and all the various ROMs out there. To remove Sense, do I need to unlock the bootloader and install a custom ROM? Or can I install an alternate launcher (like Nova Prime)?
Thanks!

To remove sense you'll need to install a custom ROM such as AOKP or cm9. Those will remove sense. You can find AOKP in the general section under the title "AOKP lives!!" and cm9 under developement. They both have flaws such as the camcorder not working, but considering the flaws that sense has out of the box, you're much better off in my opinion. cm9 and AOKP will get infinitely better in the coming weeks as they iron out the bugs. Sense is disgusting bloatware that is piled on top of stock android. It takes a ton of resources and makes even the simplest tasks a chore. Once you go to an AOSP ROM I don't think you'll ever go back. I can multi task away for hours and come back to another app that wasn't closed out of memory. Try that with sense.
To install a ROM you'll need to:
Root
unlock bootloader
Install a custom recovery
Backup your entire ROM with that recovery
Flash whatever you want
All of the directions of how to do this are in the dev section. Let me know if you have any questions.

Installing a AOSP ROM (such as CM9 and AOKP) will completely "desense" your phone.
Installing a ROM based on stock (like all of the CleanROMs) will get rid of most of the HTC stuff but Sense will still be there.

Thank you seh and rohan, I will give that a try. Will read up on it and let you know if I have questions.

Seriously just go check it out in the dev section. If you are unsure or have any questions at all come back here and let me know. I can walk you through all of it. Don't be afraid of ruining your device or anything like that. This stuff is all one click these days and isn't bad at all. I can literally walk you through every step if needed. Just check it out yourself though, I bet you'll be fine

Thanks again. Reading through the dev section now. Seems relatively straight-forward... just need to get home to get this stuff going.

FYI, the root process failed for me 2 times before it took. Just keep trying and it will go. Once you are rooted, you'll never have to plug your phone into a computer again. You can do anything from the device, no questions asked.

Here is what I'd do before installing custom ROMs etc. (Not that I am discouraging you against that but, if your device is indeed faulty then unlocking the bootloader will void your warranty and HTC may not replace/fix it.) And, you'd have wasted countless hours trying to fix the issue with software that was hardware to begin with.
1. Run the battery test *#*#3424#*#*, press 'Accept', Go to More and run 'Battery Test'. Follow instructions in there. If the battery isn't faulty i.e. after one hour the battery level is still greater than 85% (The function test shows a different number) your battery is fine. Else, ask HTC to fix it.
2. If your phone passes the battery test; turn on 'Airplane mode' when you get into an area with spotty signal. This should address your suspicion regarding that.
3. Display: display seems to be draining the most battery - doesn't mean it actual does but, at least the phone seems to think it is. Try reducing brightness to around 20% for a day - I know it is too dim but, it will eliminate that possibility.
4. If you have facebook installed - turn off all syncing. Especially the HTC sense social plugin always tries to update it from facebook.
Based on the screenshots, it seems that the battery drains very quickly when you have the screen on, even with good signal strength.
Lastly, as an alternative to point 2 above, turn on airplane mode for 1 hour and turn off sync, remove all widgets from home screen(s) and just use the phone on wifi with stock browser - see if it drops as quickly or not.
Having gone through it, I understand how frustrating this is. In the end, I rooted and completely desensed my phone (only keeping essentials - basically recreating clean rom). I do not use Auto Sync but manually engage it every few hours to update everything. And, keep the brightness to 30% most of the time.
Hope this helps, good luck.

john_tillman, thanks for the suggestions as well!
1. I did the battery test, finished at 92%. So I think I'm OK there.
2. I will try doing airplane mode before subway rides going forward, will see if that helps.
3. Something is funky with the way the battery meter app is measuring this. Basically the battery doesn't move - and then when I unlock the phone, it drops like 3%. So my suspicion is that I'm losing battery, it just doesn't get updated until I fire up the screen.
4. Yep, all syncing is turned off. I only have Gmail/Gcalendar syncing now.
I've been playing around with the phone(s) earlier as well - keeping it in airplane mode and just watching movies/etc. makes it last forever. It really does seem to be something with the signal and perhaps something in Sense.
Have you tried CleanRom? I do like the visuals in Sense, would be sad to go to bone-stock ICS... but battery is more important.

I experience the same thing. After my subway commute and after I regain signal, battery doesn't drop until a couple of seconds after o turn on my screen, but it drops like 3%.

Rooting, and unlocking the bootloader
I was able to go from stock 1.85, to sick-sense ROM in a matter of minutes yesterday. I was nervous at first even though I know what I was doing, although all was good after following the instructions given on each step of the process. I haven't really bricked a phone before because this was my first smartphone ever, But I believe that the worse thing that can happen is soft bricking your phone, which can be resolved by RUU. I hope this helps you out.
Regarding OP, I had MUCH MUCH more battery life compared to bone stock. I used to get 3 hrs screen on time with 20% brightness, now Im at 4-5 on 50% under similar usage. One last thing to note; LTE, Auto sync, GPS, and low reception, are the most battery eating thing on the phone assuming you don't have rouge apps (wakelocks).

GPS has no affect on battery life unless it is being actually used. Its not going to drain battery just by being enabled. Auto sync has minimal impact on battery as well, unless you are getting 5 emails every 1 minute. Push is always more battery friendly than pull. (unless there is heavy traffic)
About the low reception thing. While it does indeed affect battery life when the phone is constantly looking for service, it is not as bad as you would think. I sit in an area at my work that has about 1 bar of service. The phone will go from 1-0 bars to searching, about every 5 minutes or so ALL day long for 8 hours. To see the impact this had on my battery life, I did some experimenting. I basically ran my phone in airplane mode for 3 days and then compared and averaged the results over 3 days of normal use with the phone having bad service.
I lost 8% more over an 8 hour work day.

No, I didn't try clean ROM. But, I took the change log from one of the clean ROMs and deleted most of the apps that can be safely deleted. So, I do sort of have a clean rom and it works fine so far - in terms of battery life. When I used to boot with stock rom, I used to have 150 - 170 mb free ram. With the clean up that I performed - now, free RAM is 270 - 300 mb after a reboot.

Try disabling LTE and see how your battery does.
Click on mobile network settings, and choose gsm/hspa auto.

[SOLVED] [Q] Starting from scratch

I'm having issues of the phone rebooting by itself and consequently draining ~90% of the battery when it does so. I've tried flashing a bunch of different ROMS to see if I can stop it from happening, but to no avail. I'd like to go completely from scratch and hopefully I can get to a point where the phone works for an entire day without crashing. I've been using the HD2 instead of the SGS4G for a couple months now, so I'm a bit rusty, which is why I came here to ask for suggestions. This is what I was planning on doing:
- Flash one of these stock ROMs in order to get back to where I started.
- Format my SD card completely and let the phone convert it back to EXT4
- And then flash either Barebone or Valhalla
Do you guys think this would be sufficient enough to remove the problem that's causing these reboot & battery drains?

I would flash eollies kj6 with the blastoff v2 if your not planning on going to ics after because that's the latest gb kernel available and then flash Valhalla or barebones (then you might have to flash blastoff again can't remember right now but it should say in the op of each rom). And I'm pretty sure when you one click back to gb that will convert back ext4 so I would format SD card and reload it before you one click back. Good luck friend

Thanks for your input! Do you think the gremlin remover is necessary, or is it overkill in the context of what I'm doing?

If you want quick and easy use my one click the other two listed is just kernels.
As for getting battery life on ICS flavored roms, well take the time using BBS and STT to figure out whats killing your battery. As long as Im not jumping between wifi and mobile data I can go around 15 hours on a battery. And I havent spent tons of time to figure out why Im not getting more battery life. But others like jeffsf has. And with that I can honestly say if your not getting battery life comparable to GB roms its YOUR fault not the rom. Most ICS roms have stuff built in that you have to use a app for. Therefore a GB rom with nothing installed will get better battery life. But once you put your stuff on and start running the battery life is not being compared properly. The reason for this is most people will keep a app just because they are use to it and not even know the ICS rom has it built in.

I personally think most of our batteries - if still using the one that came with the phone - are starting to run their course. New batteries are inexpensive on Amazon.

I think you guys are misunderstanding my issue. My problem isn't the battery draining quickly over a certain amount of time due to regular use. My problem is that once my phone crashes and reboots, the battery will literally go from whatever percentage I was at, all the way down to below 10%. I can be at 90% battery, and if my phone crashes, it will be on low battery once it powers back up. I'm not sure what's causing the crashes, which is why I'm just trying to start at step 1 and work my way from there.
To test if it was the battery simply draining out very quickly, I turned brightness to 100% and turned WiFi & GPS on, and disallowed the screen from turning off. The battery drained normally.

That happens to me... It gets fixed by shutting down and taking out the battery for 30 seconds.

Sounds like a bad battery

i had the same issue and also would get diff battery levels when booting with or without charger plugged in...i used a toool from market to calibrate battery. i cant remember exact app but will post back if i find it.
edit:
it was "Battery Calibration"
by NéMa
and i had to do it a couple of times to get it to set in.

Like thecontroller stated its a bug and you should be able to correct it by pulling the battery out and waiting a few extra seconds. If it does it still hold the power button down for a little while with the battery out.
Do this next time you have a crash on ics. Time how long it takes for the phone to restart. It is seems abnormally long you could have some scripts that are running on boot that is causing issues.
Calibrating the battery can be done manually. All you have to do is delete the batterystat.bin file. That is all those apps do. And really If you fully charge your battery it should be deleting itself.

In a nutshell, yes. You are only putting extra stress on your battery by "tricking" it according to various calibration guides. Batterystats.bin file is generated for a reason. Batterystats.bin is in /data partition, so after you install a new ROM that wipes your previous data, it gets wiped too. So, "Wipe battery stats after installing a new ROM", which is a cliche among those guides, is pointless. Last but not least, batterystats file is simply a logging tool that monitors your battery behavior. The "stats" part is pretty self-explanatory. The actual Power Manager lies in kernel, not in /data partition which accessible to anyone.

SBD all that info is true. But if you use the aroma installer it will backup and restore the data partition. Not sure if it will restore the batterystat.bin file or not. That is why I posted what I did. I do not believe in calibrating batteries as much as making sure they file is not storing data that is out of date.

As you guys mentioned earlier ...hard resets are the best ....I find our batteries do go bad. And when they do....they do all kinds of odd things to the device

Battery calibrations are garbage. They do nothing. The file that any battery calibration app deletes is deleted by Android anytime you do a full charge anyway.

Okay, so I formatted my SD card, and flashed Eollie's KJ6 using Heimdall. After that, I flashed Raver's Valhalla Black.
Initially, I didn't install anything extra other than updating gmail and superuser. Everything worked fine, apart from one random reboot. Once it booted back up, everything was normal. Today, I installed around 5 apps. I was using one of those apps (Reddit Is Fun), and while using it, the phone crashed. Once my phone booted back up this time, everything force closed, and log provider force closed over and over. I had someone text me, and right after they did my phone just crashed. I tried fixing permissions, but that didn't do anything.
Any suggestions?
--edit--
I just factory reset and tried reflashing Valhalla Black, but everything just force closes again even on a fresh install.

Boy I don't know what the hell you're doing but you are doing something very wrong.
Flash back to stock (complete stock). http://forum.xda-developers.com/showthread.php?t=1358498
Then flash AntonX http://forum.xda-developers.com/showpost.php?p=19601810&postcount=2
Once you do that, flash a ROM.

I just went through the same issue. This was going on rarely for several weeks then got more frequent. I have a couple of extra batteries that T-Mobile sent me when I first got the phone....swapped in one and its been 10 days without a single issue. Before posting here tonight I put my old battery back in and guess what? Symptoms came back within 30 minutes....so....

Then there's your answer, you need a new battery my friend

Just so weird, I don't see how a battery can affect the OS in that way haha. I've ordered a new battery anyway, they're only like $5 on Amazon, but I'm gonna try your steps anyway, controller. Thanks a lot guys.
