Searched for this and didn't find it in the forum. My phone is not rooted.
I've had this phone maybe a week after launch and this issue has just started happening in the last 4 days or so. It typically seems to happen after charging and unplugging the phone. The stock battery usage app, Settings--> Applications--> Battery usage, shows no battery drain at all while showing the phone as Awake the whole time and Screen on the whole time.
The reality is that the phone was just sitting on the kitchen counter with the screen off and I hadn't touched it the entire time. Rebooting only sometimes seems to make it snap back to reality, there are times when I'll reboot or pull the battery and nothing happens, it just continues to give a false readings.
Anyone else experiencing/experienced this?
I'm looking for any ideas for the problem I'm having on my G2. I'm afraid it's a hardware problem and not much I can do about it.
I started having problems after upgrading from CM 7.1 to 7.2, but I don't think it was related to the upgrade. I started having battery draining problems, the phone took forever to get fully charged, and car mode would automatically start sometimes when plugging up or unplugging the charger. I cleaned the usb port with alcohol (with battery removed), let dry, and restarted. Now I don't have the car mode problem and the battery problem is somewhat better.
My problem now is that the phone will just die when I'm using it. Usually when I'm using the browser. I'll be scrolling on a page and the phone will just turn itself off. Like the battery died. I can turn the phone back on and it will start up, get all the way started back up, but while it is still loading the home screen widgets, it will go off again. I can repeat this several times. The only way to recover is to plug in the charger. I don't have to hit the power button again, just plugging in the charger will start up recovery mode automatically, I'll choose reboot and the phone will start normally then and stay on.
The phone never dies when I'm not using it. I'll carry it all day, making phone calls on and off, and it'll stay on with no problem. Mostly, I only have the problem when using the browser. Also had the problem while using my newsreader. Once during playing a game. But if I start up browsing the internet, it doesn't take long before it will turn itself off. A matter of a couple of minutes. I don't have the problem with reading emails with K9. Don't have a problem in downloading from the internet such as podcasts. Don't have a problem in sending text messages. Don't recall it shutting down while using the Facebook app. After putting up with this for a week, some troubleshooting and observations.
I never have this problem if the charger is plugged in. Only when it is running fully from the battery.
I've tried swapping to a different battery.
Turned down the overclocking with no difference.
I've changed to other recoveries, CM 7.2, CM 7.1, a CM 7.1 that I was running in May. No difference.
I've swapped memory cards.
I've reset battery stats.
No difference if running on wifi or just data.
Clearing caches made no difference.
So, I start thinking it must be a hardware problem, but then why does it only crop up when internet browsing. Must be power related since plugging in the charger makes it go away, but why does it not have a problem with using the phone in other ways?
Any suggestions on what I could try?
You could try to see if there is too much voltage drop when you start something power-hungry. Use a battery voltage logger and post the results. Start logging, let the phoneidle for a minute and then start browsing. Even if the phone shut off, the log should still be there after rebooting.
Thanks for the idea. I can't locate a logger that looks like it would work. It would have to capture a quick drop in voltage that is momentary. This problem happens even on a full battery and when the phone come back on (either momentarily or after a recovery reboot) the battery level is unchanged.
You might try as well an other way: first idle, then gradually step up to a more power hungry app to see when the problem actually happens. I have no other ideas...
Make sure that you dont have any contact with the battery and the door.
Normally batteries are covered with an aluminum wrap, and can cause short-cuts with the phone itself.
I searched it for a while with the galilio batteries.
You can try to put some saranhwrap around the battery.
I have the same problem with two different batteries. But I'm ready to try that too.
Battery graph
So here's a graph of my battery status. Long time to charge to 100%. Discharges pretty rapidly. Each downturn ends in the phone turning itself off. Notice that at 7:30 today, it turned itself off, I did a recovery reboot, then noticed it wasn't charging very well (green line turns to blue but doesn't increase), then I did a manual reboot and when the phone restarted, it showed the battery was at 100% charge (from about 60% before the reboot).
What do you think - hardware or software?

Well, I just took the cover off for awhile and tried it. Played crosswords (Shortz) for awhile with no problems. Started my newsreader (Newsrob) and it shut itself off in about 15 seconds. So, no short to the battery cover.
Same thing is happening to me. I use poweramp or the browser and the G2 just shuts off. Then I restart it and it tells me that the battery is low. Once I shut it down and reboot in recovery and wipe the battery cache it's back to it's normal battery level. I disabled data and set my phone for 2G networks only and it didn't shut off after. I'm assuming this is a wireless issue? I'm running mimicry 1.3.0 on my G2.
Had the same problem. Swapped out batteries and problem gone.

Did you swap the battery and immediately have no further problems? I tried swapping my battery already and still have the same problem.
1. Bought it used - c6502. Phone arrived with around 10% battery, everything looked fine and then it kept shutting off every time I tapped the camera icon. It was on android 4.4.2
2. Charged to 100%, after hard resetting (using the button next to the microsd slot) couple times, it finally turned on, updated to 4.4.4, used it whole day without any problem and then google play services, xperia home, camera common or something simlar and whole bunch of craps stopped working when battery was around 20%. Phone was STILL on. So I turned off the phone and can't turn it back on now. Tried the hard reset button, Sony & the xperia logo show up, then I see the gray screen only. The on screen charging indicator shows around 3 bars which should be good enough to power up the phone, but it doesn't turn on! I'll let charge it fully and try again.
Can a bad battery stop all these services? or is it a software issue? As I said the phone was still on when all these services started crashing.
After reading some other threads, it feels like some kernels have battery drain issues ( I even don't know which kernel mine is running, used it for a day only). Should I try to flash a different kernel? Could you name a few that don't have battery drain issues? Or should I just get a new battery?
Thanks!
Hello everyone! Recently my Note II started to behave differently. Whenever I charged it completely, the battery abruptly fell to sometimes 60% sometimes 40% immediately followed by low battery warning indication and shutting down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon as I put it idle it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery
After charging phone to 100 it will only work for short time and then it will randomly shuts down (usually the moment u use it, like unlocking the screen or getting a call). And then it wont turn on until u start charging. Sometimes when u plug it back in battery is at ~90%, sometimes it goes back to 0. I was thinking it was battery's fault but almost every time this happens my phone does some kind of soft reset, sometimes my themes reset back to stock, sometimes my saved wifi dissapear, notification settings reset, etc. Phone has the screen replaced a year ago too if that could add to it.
You can try to revert it to stock, but most probably is a battery problem.
I've been using my phone for 3 years already and a half year ago I noticed that id didn't hold a charge when the battery went below 30 % . it randomly shut down below 30 % epsecially when I tried to take photos or use flash (that require high Amperage) . Sometimes it restarted itself after unexpected shut down and as I noticed dalvik cache was formatted/deleted. so I had to login to my google account set themes and etc. after I upgradet to 7.0 every unexpected shut down began to worry me becaouse even app data began to dissapear. So a week ago I ordered a new battery and now I am relieved . in my opinion it's 100% battery problem .
Definitely a dead battery. 3 years is a long time for these batteries. You did well to get that long from it!.
Thank you for this thread. I was starting to go loopy because I thought it may have been some app. Same issue and I need to find a battery guy.
