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.
Hi guys,
starting from about a week ago I'm experiencing some problems with my Galaxy Grand Duos.
All has begun with the touch screen: when I try to trace the unlock sequence it seems to lose the contact with the finger so I've to try more and more times. Also with the normal use of the touch with other apps it is not working as before.
Now it's from a couple of days that the phone, with a battery charge of more than 80%, suddenly automatically power off.
When I try to turn on the phone it turns off again and again, and the battery level of charge seems to be randomly generated each time.
If I'm connected to a wifi network, after a random times of reboot it restart to work, always with battery level and touch issues.
Otherwise if it's using 3G data battery lows down to 2-3% and the phone can not stat anymore on and turns off.
Battery consumption app doesn't show anything strange: screen 29%, multimedia 18%, play services 14%, Android OS 13% and so on.
The Android version is the original 4.2.2, kernel 3.0.31-1226815. The phone has never been flashed or customized.
I'm thinking about replacing the battery, but I'm in doubt how it can be related to the touch screen issue. Can you help me?
Can I use EB-L1G6LLUCSTD battery, which is for SIII but is 2100mAh as EB535163LU?
Thank you all in advance!

Touch screen issue is directly related to your battery. Take a good look at your battery to see if it's swelled. When the battery is swelled the phone tend to bend a bit because of the pressure, hence the touch sensitivity goes haywire.
Remove the back cover while the phone is turned on (don't remove battery) and see if touch issue is still there. My guess is, you have to replace your battery, If mentioned battery fit's your grand and voltage is the same, there's no doubt you can use it.
When I charge my battery and it is 100% my TAb S is switching off. I only see the battery picture showing 100%.
I did a hard reset and a clear install without results. Anyone an idea what happens?
Are you saying it switches off completely or the screen does?
It switches off completely, not only the screen.
I had this problem a couple of weeks ago,has soon has the tablet booted up it would switch off then I would have to boot up again,then it would switch of again.i had the battery changed by Samsung about a month ago it started switching off since that battery change,the new battery started discharging just like the first battery,the tablet is now back with Samsung,i am hoping to get it back in the next couple of days,lets hope they fix it this time.Longlegs
After having headache with this problem for last one month and lost hours of testing, i finally found a problem so lets explain symptoms, maybe it will help someone.
I am using CM since first version and as all nightly version have some bugs i had them as well. So i had random reboot from time to time and i thought it's just CM bugs.
For last 1 month reboots happen most often and always when i receive or make a call.
Phone just reboot and loop at boot loader. After removing battery for few seconds phone can normally boot.
3 days ago phone started to reboot even with some heavier app's but never if i disable network. Reboots start to happen even if phone is in my pocked and i exit elevator (drop network and get again).
I tried clean installation of CM12.1, Clean installation of CM13, Wiping internal storage, Clean installation of Cloudy ROM, Removing SIM card, removing SD card i even moved back to stock ROM.
Installed more then 30 app's for monitoring everything and noting show any error, problem etc. While doing all this, i realized that this problems never happen when phone is at charger. Again, installation of 20 apps for battery calibration, voltage monitoring, logs etc. and non of them showed any problem.
Battery was regullary fully charged but noticed that it happen only with heavier usage (have call, copy bigger file, start game).
After doing that tests for entire day, phone refused to pass boot loader with battery but boot normally with charger.
So i purshesed new battery last night, phone booted normally, there is no reboots or any issue at all. Now i can compare that new battery is better since it lost only 1% of battery over the night but old battery didnt show up any problems at all. It's normally to not be that good after 1 year of usage but I didnt had any drainings, it was regularry charged etc.
So if you have similiar problem, to go to some service where you can try with new battery before buying one.
I have the exact same problem .
It driving me crazy! I will try to get new one, and reply as soon as possible ! I hope it will work.
the phone just showed me that The battery that I was using it for one year is fake -_-
Yep, same issues, phone was rebooting sometimes (at the begin, only a few reboots, only during the launch of "big" activities like GPS, or photos) then a few weeks later
I needed to connect it to the charger otherwise, after a few seconds, the phone used to reboot in loop... Until it dies...
Buying a new battery resolved all the issues, no more reboots at all
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
