Guys,I own a T Mobile G1 Android 1.6 Phone and recently I’m facing some problems. The problem that appeared recently is with the battery drain. before some days ago the battery of my G1 lasted up to 4-5 days, without using Wireless, GPS, and Bluetooth. If I used the mentioned services normally the battery lasted up to two days. But recently the battery is draining too fast. Within 4 hours the battery goes down less then 15% even I do not use any mentioned services. I keep my phone on standby, without talking a single minute with the phone, not using any service etc, and again it goes down very quick. I took some measures according to HTC instructions how to save the battery but again it does not function. I uninstalled all applications and reset the phone to factory setting by again same thing. Then I searched on the Google some instructions, I tried also that one’s but again it does not function. I always used HTC charger that came with the phone but again same problem. What is the strangest thing that after some days the battery gets back and works perfectly for two weeks, which means I use the phone normally without charging 4-5 days. As I operate very well with the smartphones, Pocket PC’s etc I start analyzing G1 and monitoring very closely why the battery goes down, I monitored for a long time the query under the :About Phone-Battery use- and I see there that Andorid OS is using the battery from 76% up to 85%. Now it came to my mind that something is keeping engaged or it keeps running the Andorid OS always on. Then I suspected that thre my be any virus on my phone, but I installed form Market Flexilis/lookout antivirus application, but there was no virus and again the battery goes very quickly down. As I said after sometime the system returns to normal and the battery lasts for 4-5 days, and when I check the information under Phone,Battery use, I see that the Andorid OS is spending only 6% of the battery. Comparing with the previous description it is a huge difference. According to my opinion there is a small problem with any file which keeps always running to much the Andorid OS. Can you please give me any instruction why Andorid OS is spending that much the battery? Or give me any instruction how to prevent this operation that keeps Android OS to much engaged? or is there any programming mistake?, is there any need for update?, do I need to root my phone as it is not rooted? The reason why I’m thinking that there is a technical problem is because sometimes the system gets back to normal and sometimes it goes out of normal running. I appreciate a lot if you could help me to resolve the mentioned problem.
I've noticed the same thing on my G1 sometimes there is fast battery drain and it seems associated with Android OS. The percentage is over 70%. I also notice it be associated with the display as well. Could be that there is some process that won't stop running and is using Android OS or it could be that on other occasions the display is not going into sleep mode properly. I wish I knew how to fix these problems but I don't. I just observe them.
The battery issue, is an up and down problem for me. Sometime I can go through it in one day or less, other days it will last me for 2 plus days.
It also could be that the battery need replacing. Who's know.
I just bought a 2nd hand G1 - works just fine. I rooted and installed CM6.1.
My battery drains within 1-2 hours. I've tried various methods of resetting stats, with no luck. How frustrating! I wonder if it's a battery hardware problem or software?

I also faced bad battery life on various roms. Since I'm using COS-DS (android 2.3.3) http://forum.xda-developers.com/showthread.php?t=950765 and the Biffmod kernel http://forum.xda-developers.com/showthread.php?t=950765 the phone runs more than 24h when texting and calling. Of course you should apply the 14MB RAM hack in comination with this kernel http://forum.xda-developers.com/showthread.php?t=831139. On standby (everything off, except data and 3g) my G1 runs >48h, before it needs to be plugged in.

Sounds like the basic description of the USB Charging Bug.
The bug triggers if the G1 is using a kernel starting 2.6.35 and onward tree, and charged using the USB instead of AC wall charger.
A couple of option to avoid the super discharge after that (you can use either);
1. Reboot after you unplug the USB charger.
2. Change kernel to one from 2.6.34 tree
You can also visit the Dev sub-forum, there's a thread there discussing the debugging process.
It is so unpredictable for me...I have just got into the habit of a reboot after unplugging USB.
Battery drain on the G1
I have the same problem. Even on standby it drops to less than half of its battery life. Sometimes its worse. today i noticed that the battery percentage was at 84. Next thing I know the phone reboots itself and it displays that it has 1% battery, battery icon empty all in red and LED flashing in red. Then I turn it off connect it to the charger, after a couple of seconds I turn it back on and says its 90 something percent. Could be a virus or just a battery bug,that's my guess. I scanned the phone with Lookout Security and there was no Virus,malware or spyware found.
I want to try different kernels for this battery issue but want to make sure I am installing the right one.
I have CM6.1 with 2.22.23.02 radio and DangerSPL installed. Can I just load any of the kernels built for EBI0?
Specifically, can I flash the kernel in the 1st post here? http://forum.xda-developers.com/showthread.php?t=1010932
Thanks.
After updating to 2.3.3 using COS-DS, my phone seemed to work fine. I initially had a battery drain with nothing taking up large battery usage, so I reset the battery stats and all was well.
However, after unplugging my phone from charging all night (100% upon unplug), I checked my phone two hours later and saw that my charge was down to 22%. Upon checking Battery Usage, I found that Android OS is using 76%! The only thing I've done today was answer a couple SMS messages. I don't have Sync, GPS, or Wifi on, but I do have Mobiledata and 3G+2G on, as well as Background Data. The only widget I have is Google Voice, which I've removed to no avail. I've tried rebooting (twice), but it stays the same. I've turned off data, gone to 2G-only, and turned off background data, and it still continues. In Spare Parts, under Battery history it says that the only thing using up the battery is Suspend in CPU, and Battery Status says that the battery's health is good. Something really strange is that after the initial power-off upon the discovery of this issue, I immediately plugged it into the charger. After about 3 minutes I turned it back on, and found that it's already charged back up to 86%. WHAT.
Also, I haven't plugged it into the computer once in the last few days, so it's not USB-bug related. Any ideas on what's going on here?
EDIT: Ok, it's been a couple hours since this began, but just now I checked the phone (it was on the charger) and suddenly EVERYTHING is gone from the Battery Usage page, save for Display and Android OS, and Android OS is back down to 5% now. Really bloody weird, but the issue seems to have resolved itself.
I've had similar issues. When my battery runs flat, dead. I plug it up and switched it on, and it shown "Charging (32%)". I get different but similar results with different ROMs. It could simply mean the battery is wasted couldn't it?
Have you gone into the Recovery mode and wipe the Battery Status? I was having similiar issue (but not a fast drain), I did maybe about 5 wiped and reboot the phone. My problem seem to go away.
I went from 1 day or less from 100% to having to recharge, to 2 and 1/2 days then charge.
The issue came back later that night, and has been happening ever since.
I've done the bump charge + stats wipe, where I let it charge to 100%, shutdown until green LED, wipe stats, restart, let drain to 0, restart and use. I've tried this about 3 or 4 times, and the issue persists. I've removed my 2 widgets (two sound effects widgets), and it persists.
Also, I've downloaded OS Monitor, and it shows the CPU to be resting at its min, 246.
I'm hoping it's just the battery at this point, and have already ordered another one. I'll let you guys know if that fixes it.
In that case it might be your battery that need to be replace. How old is the battery?
I really have no idea. I bought this G1 used on eBay 9 months ago.
2 things to note:
1. It actually stopped booting last night even while on the charger: I restarted, and it kept getting stuck on the splash image. So I superwiped, reflashed, and the drain is still there even with no user-installed apps.
2. About a month ago, (when I was back on a stable Froyo, which I had been on since I got the phone 9 months ago) it started to randomly shut off. It seemed like if it got just a little too hot (battery got to maybe 30 C, never was able to check what the temp was when this happened), it would shut down and wouldn't get past the boot screen without a reset. I had to either charge it or wait an hour for it to successfully boot again.
In retrospect, this is sounding more and more like the battery. The only thing that's strange is that Android OS takes up such high percentage. Oh well, hopefully the new battery gets here today or tomorrow, hopefully that fixes everything.
Since you have brought the G1 9 months ago, more than likely it's had been over two year or more (about the same age as mine more or less). I doubt that the seller would be giving you a brand new battery.
I noticed the reboot on mine G1 too. Ever so often, my G1 will reboot on me. But I do not have the problem getting stuck at the splash or boot screen. But then I am using the SuperAosp ROM not Froyo.
Let me know how the new battery will work out, I might have to end up getting it myself. Eventhough my battery life got better after I did the wipe battery status, sometime it still drain depending on the day I guess.
I noticed the same result with COSDS.
I moved to Ginger Yoshi with much better results.
Better, but not as good as stock, obviously.
COSDS turned into a real hog on me by the time the second or third reboot happened.
Heeter
I'll stay with SuperAosp, I take the performance over the battery life any day. My battery status an't that bad. Once in the while I used it up in a day or less, other I can stick around for a few days.
The rebooting part was not too bad on my end. Just once in a while. Nothing I can't handle.
@ psychosonic - You might want to try that if you want, Gingerbread Yoshi was one of my first choice before I found what I had.
Alright, got my battery. After calibrating it for one day, then using it today post-calibration, it's functioning phenomenally. After using wifi + internet for a period of time, and sms throughout the day, it's still at 70% 6 hours after charge. Essentially, the only thing that drains the battery is heavy internet use, which seems to make it go down 1% per 2 or 3 minutes.
Internet usage seem to take a lot out of the battery for sure. I know mine take a lot more than 1% every 2 or 3 mins when I use my internet.
Let see how will the new battery pan out. See if it will last you 2 or more days. Keep using it as such, and see where it goes.
Android OS Battery bug
Hi!
1. Install SystemPanelLite Task Manager from the market.
2. Run SystemPanel and open settings and check the "System processes" option. Close settings.
3. Scroll down in the process list until you find the process "android.process.media". If you have a CPU usage of more then 10-30s and the process usage gauge to the left moves up and down you probably have the Android OS battery bug.
At this point you can try the following;
- Shut down your phone. (Not just turn it of. The complete shut-down-power-off-thingy)
- Remove your external SD card.
- Start up your phone again.
- When the scan media is complete, do step 3 above again. If you don't see the problem at step 3 your SD card has a corrupt filesystem. And needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Unmount SD card
- Format SD card
- Restore files from your backup.
If the problem persists your internal SD card might have a corrupt filesystem and needs to be reformated. Follow these steps;
- Backup your data first!!!
- Settings -> SD card & phone storage
- Format internal storage
- Restore files from your backup.
More details; What happens when you have a corrupt filesystem is that android.process.media tries to read a file but fails over and over again. The filesystem might not look corrupt to you. And you can read and write files on the SD card without problems. But at some point the android.process.media failes to read the files and loops like crazy, draining your battery.
I had a corrupt filesystem (FAT32) on my external SD card. I also had Android OS battery usage of 60-70% and a fast draining battery. I hope this can help others.

Dear fellow enthusiasts,
since a couple of days, I'm experiencing sudden device crashes when I'm using it for network related activities, mostly over the 3G network (for example, I'm typing out a message on the Facebook app, and the phone goes into boot loop or simply "shuts down"). I had only recently upgraded to the 4th beta build for the Cyanogenmod 9, hosted here on XDA , so I suspected it would be related to this. However, upon reinstalling both the previous version and the new mod from absolute scratch, the issues remained the same.
I had noticed that after each crash, the battery charge displayed as very low (2-6%), whereas I'm certain the charge should be much higher. So I thought it might be some sort of corrupt battery-cache issue or something.
However, and here's my actual question, I just now noticed that my I9001 battery is slightly bulged, on both ends. This bulge starts just above the white printed SAMSUNG lettering, and it ends just bellow the QR code. I can't for the life of me remember if or not this is normal, so could someone please confirm this for me?
And while we're at it, could a faulty battery affect my performance as such (making my phone crash etc)?
Thank you very much in advance for any help or information anyone could give me.
I confirm, battery is slightly bulged in those places but it looks like a production "thing" to me (I hope I understood what you mean), no need to worry, I guess. Looks like corrupted battery stats, try to wipe it via recovery (phone fully charged, plugged in - then wipe battery stats). After that, i recommend one or two full battery discharge - charge cycles. I've noticed hovever, that after each full factory reset I have for about 20% better battery drain, than after flashing many ROMs, kernels and updates (cache and dalvik cache wipe only), my battery drain is getting pretty annoying. Try a full factory reset, if wiping battery stats didn't work.

Hey people,
I received my new battery last night, I went for an Akku Powercell of 1800mAh. Charged overnight, been using it all day, no problems whatsoever to be found.
Thanks again for the assistance!
Swollen battery = defective!
I'm sorry but I've encountered this as well in the past. Normally working phone with sudden shut downs and huge drops in battery charge. It took me a long time to convince me that the battery was defective. So maybe this would save you guys some time in finding this out!

Hey, try to use cm10 for a few days, if the problem gone then your battery is alright, and please stop using beta roms, regret are so buggy and slow: )

In general healthy batteries DO NOT swell. Buy a new one before it explodes or starts leaking...
Hey all, just because people keep on posting, the battery was indeed defective, the roms were absolutely fine and the new battery is performing marvellously!
Thanks again for all the input !

I have the exact same problem with my sgs i9000-gt.
My phone turn off itself ( no restarts, its a complete shutdown ).
First, I thought i might be a problem of GB 2.3.6 rom i was using, so i updated to latest cm10 but the problem persists.
If you restart the phone after the shutdown than i shuts down within a minute again.
Also the battery drain is pretty fast. I notice the same bulges on the battery as reported in this post.
I did the battery calibration thing as some people suggested, but that does not solves the problem. However, it got rid of the fast changes in battery status which was happening before. Like when you restart after shutdown at 80% battery status, it will show like 2% battery left and after few minutes of charging it would boost back to 80-90%.
But still the battery drain is pretty fast. It discharges from 98% (i cannot get to 100% charge, 98% is highest) to 50 % within an hour, just idling.
And when i am around 40% or so and if i recieve some message and try to open a app it shuts down again.
I have ordered a new battery just in case. Will update here if that improves things for me. But i will still like advice on which is a more economical kernel and rom for i9000-gt? Some people suggested slim bean + semaphore on some forums but i would like to have some more concrete advice before i change more things without knowing the source of the problem. I would be grateful if someone can suggest what is best to use with some details( version, etc). Thanks for that in advance.
I thank you all (users + developers) for all the useful information provided on this forum, i learnt a lot although i still am not able to fix my problem . And I hope someone might come up with a concrete solution for this problem. If there is a solution which I might have missed, I thank you in advance again and hope you will be kind enough to point me in the right direction.
cheers
update: the phone stays alright if u dont do anything on it, but the moment you being doing something on it other than playing with system settings, like run some app, especially something that uses network / wifi, it shuts down. none of this happens though while its plugged in. it happens only when its on battery.
problems fixed so far after replacing the battery

I flashed back to stock samsung rom ( from the value pack) and the problem persisted.
today my new battery arrived and all the forementioned problem seems to be gone with the new battery, my phone seems to be working fine for last 5 hrs without any restarts or crazy battery drain. will test the same with custom roms again. As of now it only seems that problem was the battery.
Cheers.
thanks to the forum and developers
Hi,
I'm experiencing this problem more than 1 month. I'm on CM10 with kowalski kernel. It seems my phone sometimes wrongly read battery status and drop battery level percentage from some value to 0 immidiatelly...and shut down occurs at the moment. I thought it could be caused by old battery, but it's not - I buy the new one and the problem still persist and it's VERY irritating...Any solution?
Thanks Jiri
Hello,
It happens also for me but only when I am around 15% and when somebody call me sometimes it fail down sometimes.
It seems that the deep sleep do not allow the system to read a correct battery value when screen came back and the system shutdown because of a too low voltage.
I did not found any solutions in several type of ROM.

Mmmhhhh I actually cant remembet them stating that it will be fixed. I remember tony mentioning that its a low priority rom bug. It might be fixed with 4.2.2 but i am not really sure. Regarding the issue I do experience it too but only once every few weeks.

I also have this shut down problem. A lot. Maybe 5 times a day and its also driving me nuts. Mine does not happen while phone is in charger - so its probably the "battery reporting wrong charge" problem. Im on new bootloader. I've seen it go from over 50% to 0% battery in an instant.
It might have happened before but much less frequently than now. I started noticing the problem a few weeks ago on Pengus CM10 rom with kowalski kernel (before reading about it). I reflashed the kernel a few times and upgraded the kernel once or twice during that period.
I switched to PA 2.6 - 10 without improvement (KK-116). No apps installed (except Antutu)
I even had the problem in TonyPs TWRP 2.4.3.0 when trying to backup my rom once. Phone shut down while running the backup. Plugged wall charger in while phone still being off and saw that i still had battery left - probably 30-50%. The LG charging graphics icon showed this (you know, the one that shows up if your phone is off and you plug in the charger).
I Tried the following using AIO v5 tool without luck:
1) Reintalled unlocked ICS bootloader
2) Reverting to Old bootloader / partition - then back to new bootloader. Then installed ROM.
I have also tried installing Django Manouche X 1.6.1 (KOB 0.7 kernel) and running Antutu a few times (right after first boot + reboot) with the same result: shutdown. No apps installed.
I can always reproduce the issue: run Antutu benchmark 1-5 times in a row manually on battery. Plugged in, this does not happen.
It happens with or without OC/UV.
I havent tested it extensively, so I cannot be sure, but it seems to me that the rom/kernel isnt the problem since it also happened (once) in TWRP. Could it be the bootloader? Granted this is only a guess, since i have NO knowledge of Android programming or inner workings. Or maybe this is what happens when the LG battery is dying? I got the phone just as it came out.
Edit: BB 30A
I guess i have the same problem but either worse or something totally different.
Regularly around 70%, my battery just drops to 0% and my phone shuts off. It can happen anytime for me and it usually happens just after about 10-15mn of using my phone.
This morning it shut off at more than 90% and then got stuck in a bootloop i presume because it says it doesn't have battery.
Update:
I tried reflashing 30A BB. Didnt help.
Tried Django Manouche X 1.6.1 with kernel without zRAM or ramhack mod. Didnt help.
I Also tried PA 2.6 - 11 on old bootloader, and the battery-jump shutdowns continued when running antutu.
Flashed (completely stock - no rooting etc) ICS 30A with 30A BB through AIO v5. Didnt help. No tweaks or apps (except Antutu) installed. On Antutu run number 5 the phone restarted (with bootloop). Had about 36% battery. Pulled battery, rebooted, phone shut down before booting ROM. Plugged in charger, booted into ROM, showed 100% battery for 10 seconds before showing 30% battery. Tried with quadrant and 30% battery: phone shut down on run 2. Pulled battery, rebooted. Messed around with camera and gallery for 5mins at 26%: phone shutdown.
Im totally lost ... if its not the battery (as indicated by the first post (OP)) i have no idea whats going on. Maybe some other piece of hardware inside the phone is to blame. A piece of hardware that is only called upon when on battery and not when on charger. Maybe a power regulator (or some such thing) is broken?
Next test: Stock GB with GB BB
Edit: Well, the GB ROM + GB BB didnt work either: Gueste2X GoodBye v2.0R + 20L BB rebooted at 75% battery running Antutu. It showed a pop up about low battery and shut down shortly after. For the first time the battery icon still showed 75% when it shut down though.. And this time it showed 21% (not the usual 0% battery) when rebooting to ROM.
I think Im throwing in the towel regarding the software.
My dad also has an o2x, so i will try and swap the batteries and test both phones. I will ofcourse run antutu several times on my dads phone before swapping the batteries..
Update 2:
So i tried my dads O2X battery in my O2X. I Ran Antutu quite a few times and my phone didnt shut down. So I'm pretty certain my battery is messed up which is the reason my phone shuts off "randomly" showing a sudden 0% battery.
Through a google search i found a guy stating that the battery often starts "bulging" when its messed up like mine. His test was to lay the battery flat on a hard even surface and spin the battery. If it keeps going for a couple of seconds it might be messed up. My battery is definitely "bulging" and spins for much longer than my dads. His spins for less than a second. Mine spins for maybe 2 seconds. Not very scientific, but i could definitely see a difference. And i can see the excessive bulging on my battery if i look at it from the side.
So Im ordering a new battery tonight - the originals dont cost much thankfully.
Hope my walls of text can help others in the same situation.
Last update (promise):
Got the new original battery today. Charged it to 100% and used my phone for various tasks until the battery hit 70%. (This was my old batterys absolutely certain "breaking point" when running Antutu benchmark. On my old battery Antutu would crash on first or second run every time when battery is at 70%.)
On the new battery i quit running Antutu after the 13th run in a row without a "battery low" shutdown. The battery was at 40% after the 13th run.
I lay the old and the new battery flat on my smooth metal mousepad and spun them around. The new battery spun for less than 1 second. The old battery spun for almost 4 seconds on one side - almost 3 seconds on the other side.
Two working batteries (my dads 2+ year old battery and my own brand new one) performing equally and at the same time differently to one defective battery. It lends some credence to "the guys" theory that battery defects might result in "bulging" of the battery.
Which means, your battery can be defective but not "bulge". If however, your battery is "bulging" something likely is or will be defective. Fantastic knowledge to posess, if true.
It might seem like a "well duh, thats obvious" revelation, but Ive held my old battery in my hands a lot the last 2 years (especially lately) and I did not notice the "bulging" at any time.
Hi guys!
I've been experiencing some SoD (Sleep of Death) episodes about 3 weeks ago. I've been searching for a solution ever since.
Specifications:
Phone: Samsung Galaxy S i9000;
ROM: currently stock 2.3.4 - I9000XXJWQ
Problem:
-phone keeps shutting down by itself, regardless of what I'm doing. Sometimes, when I reboot, the battery level shows 4-14%. After a second reboot, the battery shows the normal level of 60-70% (the level that was shown when the shut down occur)
-drastic drops on battery levels (screenshot attached - I've been experiencing some more drastic drops than that)
Tried, but no results:
1. I tried other ROMs (6 of them), from JB to KK (Cyanogen McKay SlimBin etc. found on xda) +wipes
2. I tried other battery - still my phone shuts down itself
3. Flash stock kernel and ROM with Odin
4. Battery recalibration didn't work either- I don't know if I made it correct. Read here a post about it and I understand that wiping batterystats.bin dose nothing but clearing the history of the battery consumption. Also, I think that flashing stock ROM took care of wiping that file so no need for calibration (correct me if I'm wrong please). Also, I think trying another battery excluded the possibility of a faulty one.
5. Checked the connection between the phone and the battery. Also I've wrapped the battery in a paper to make sure it didn't move. The phone shutting down even when it stud still on the desk made me think it was not the problem.
6. Wi-Fi setting about sleep: From "Never" to "When screen of"
Q: What do I do next?
