My phone has discarged is just over 2 hours! All settings are normal, battery usage noted screen 41% exchange 25% and email 21%. While screen goes dark, it appears the screen is still using juice in the background.
I had the exact same batter drain problem happen to me today after installing the 4.2.2. OTA update. I got prompted to install the update shortly after 9am this morning (90% battery) and my phone was dead by noon after zero usage. I left it off and charged it for an hour in the afternoon, getting the battery up to 25%. After powering back on it was dead again in less than an hour.
Tonight after again plugging it back in I noticed Exchange reporting 57% battery usage. I've since deleted and re-added my Exchange account, and am really hopping that fixes it. We'll see what happens tomorrow, but certainly not a happy customer right now.
As near as I can figure there is an issue with the 4.2.2 update and the exchange services at least with certain exchange server configurations and upgrading the corporate settings during the 4.2.2 update. After the 4.2.2 update and it upgrades the corporate account settings something is not right in the updated settings causing the exchange services on the local phone to continuously run using a huge amount of processing time and quickly draining the battery. This also causes the area near the top of the phone to become very hot.
I was able to fix my problem by disabling the exchange services, removing the corporate account, shutting down, removing sim card for 10 seconds (likley not needed), restarting and re-adding corporate account. Phone is now operating normally, exchange services not running abnormally and no battery drain.
Just a heads up for those who are seeing battery drain but don't use Exchange: I saw someone on another forum mention that there was a problem with HD Widgets where it would constantly crash and restart, pegging the CPU at constant ~100% usage (with corresponding heat-up of the phone). I'm not sure of exactly what part of HD Widgets was causing the issue, but when I uninstalled it, the problem instantly disappeared. CPU usage dropped to normal, and it's charging at a normal rate again.
Thanks edevries, I'll do that, I see I have HD widgets too. Also, I see that I can now charge on my computer or car, while before it would drain too fast to keep up. I'd done the major exchange uninstall and reinstall.
I've just unistalled HD widgets. fingers crossed...
My battery drain has been fixed! My CPU was constantly at 90-100% (making the phone extemely hot). It turns out that HD Widgets app was the problem. They released update 3.9.1 (Fixes for CPU spikes in 3.9 release). Now the phone is back to normal. I would suggest using "System Panel App / Task Manager" app. I was able to tell when the CPU issues started, and figured it was from app updates on Monday morning. Hope this helps.
Yahoo!!! Between the HD Widgets and Exchange, my phone is way back to normal, and even better! So not sure which it was, but I did both and now it is good.
Later in the day: Seriously, my battery is just at 87% 3:30pm and normally it would be down to about 60 % or less.
It's been a couple days since I started this post. My phone battery is now performing noticeably better than before the update. Deleting then re-installing Exhange helped the most but I also had to remove several "full contact" widgets and re-install them. Interesting that the Direct Dial widgets I had didn't cause a problem.
I did a full factory reset and have not recreated my corporate exchange
account. The heat is gone but battery life is still noticeably worse than
before the update. I lost 20% of battery life over a half-hour lunch just
answering email and checking the news. I have not installed HD widgets.
Display takes up 52% of battery use. Notable was losing 15% of battery
life when the phone was in sleep and airplane mode for 2 hours.
As I posted in another reply I'm experiencing improved battery life.
experienced the drain yesterday when i updated to the latest software. removed my exchange accounts and it seemed better... however, today my power button has not been responding much. to get the phone unlocked/out of sleep mode, i've had to remove the battery then put it back in. the phone would turn on automatically.
but now the problem is that the phone won't even come on at all. plugging in, removing the battery, etc... none of that turns it on. the only thing i can see is the power charging when i have the battery in and charger plugged in. what a pain.
The update that HD Widgets sent out earlier today seems to have finally fixed it for me. As soon as it finished installing, my phone's batter graph leveled out and it physically cooled down (it's been warm since the 4.2.2 update over the weekend) and my battery graph leveled out. It's been back to normal ever since. I did the Exchange account reset a couple days ago, though at the time it did not seem to help with anything.
I almost wonder if the update caused similar conflicts with multiple applications, and you have to get the ones on your particular phone all fixed before it settles down and starts working correctly.
I can confirm that doing a factory reset has cleared up this issue. I had a battery drain first from Exchange Server, so I did the disabling and cache clearing fix, in addition to the deleting of the account and re-adding. I had the HD Widgets drain until they released the update. Finally, I had a random drain from Google Maps. I did a factory reset yesterday morning, have charged the phone fully, and now my biggest drain since full recharge is the screen (as it should be). I would recommend doing a factory reset for everyone. Not only does it seem to clear up all these issues, but the phone is running extremely fast now (even after my 32 apps were re-installed).
nVsOne, so when you do the factory reset, you no longer have the JB 4.2.2 update correct? You have no updates, correct?
Incorrect ... a factory reset will not remove an OS update.
The factory reset does not purge Android updates. You will have 4.2.2 afterwards, but it will actually work as intended.
Actually, the factory reset erases everything and sets the OS to 4.2.2 afterwards. It's basically a fresh install of the latest version of Android.
Ah.... I see, Good to know. I didn't know that. Thanks for the clarification.
I am getting this same issue... Don't have exchange, HD widgets, and have performed a factory restore. Still having the problem. This is getting out of hand, as I can't even get through until lunch the last few days.
Same issues, no exchange services on my phone though.
VZ sent me out another Gnexus - making it my 3rd, got a new sim card as well last night
RARELY have more than 2 bars of 4G - confirmed with a tech yesterday that there are !!!6!!! towers within 2 miles of my house. While my wife's AT&T iPhone5 has full LTE allll day everyday. Neighbors VZ iPhone5 had 4/5 bars when I checked with her yesterday
I can drain the battery in less than 2.5 hours and I have the extended battery. It also gets extremely hot after ~10 minutes of use.
The 4.2.2 update destroyed what was ever left with this phone....which wasn't much.
People recommend rooting and flashing ROMs but I am over all of that, give me a phone that WORKS.
