Battery issue

The other morning I woke up and unplugged my phone and the "Unplug your phone" notification wouldn't go away and the phone thought it was still plugged in. If I rebooted it would just turn off and keep going from the green batter charging icon to a black screen and back. Only way I could turn the phone on would be to actually plug it in again. Problem fixed itself that evening and the phone was fine for a couple days. Today the phone started with the same thing.
I've tried searching but couldn't find anything on this specific issue. Any insight? Thanks in advance.

Brand new ept4g and I got 6hrs of battery life its so lame I have hack so much bad luck with this bad boy but I'm not giving up.

This isn't a battery consumption issue...

Anybody have this problem yet?

I'm having the same problems the last few days. Also when I unplug my phone I get a red exclamation point over my battery widget, when i open the widget it says that the battery is over voltage and the red led light won't go off. Think i'm about to go see what best buy does for me. Been dealing w/ this problem for a few days now.

Did you get a replacement? I haven't had any free time to go to sprint with my problem. It is still happening often though.

I had a similar issue the other morning. Though my phone would only boot back up in recovery mode. I reflashed it to out of the box stock but that didn't make any difference. When it did boot up it would show that it was connected to the usb port but it would not be plugged into anything. I plugged it into a usb port on my computer that I hadn't used with the phone before and it reloaded the drivers on my computer and "that" issue went away. After turning phone off it would start rebooting itself immediately or with in a few seconds of turning off. I let the battery die completely and then recharged it and the automatic reboot went away, at least for most of the day, but last night I turned the phone back off and it rebooted itself. I did reroot and restore my phone after I got it to not show the usb connected or the battery charging while the phone was off icon. Just wish I could figure out why it wants to automatically reboot itself when I shut it off.

Same issue here

My Battery Monitor Widget shows a max of 1500mah? Wtf? And a measured of under 1200?
No wonder my battery life is crazy low...

I figured a way to shut the phone off and not have it automatically reboot. If after shutting the phone off the normal way and once the screen goes black but before the capacitive lights go out, if I again press the power button, the phone finally shuts down without rebooting itself. Not sure why this is happening but at least I can get it to turn off now.

I found better battery life by determining which app or apps drain the battery. I used Battert spy, cpu spy and system tuner. My problem was Touchdown exchange for Androir 2.x. I switched to Moxier Mail. I would get hours on moderate to heavy use. I got 22.5 hours yesterday on moderate use.

[Q] 100% full charge to 0% in 6 hours??

I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?

Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

unrooted.
I have to leave for work now with out a phone, I will try to check up via computer (feeling like a dinosaur).

Ha ha I know I feel so bad when I don't have my phone. Maybe see if it happens again tonight. If it does I would get on to the carrier. Have a good day at work!

Ill try both.

It has been documented the Verizon has battery issues but not sure if they were meant to be fixed in the 4.0.2 update

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery

If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck 

My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings

how do you disable drm? and what exactly is it?

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.
Good luck.
BTW, both actions can be reversed.

My G2 will shut itself off - any suggestions?

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.

Last night my M7 turned off to "rest"

I have no idea why some person thought it was a good idea to program a feature to turn your device off randomly. My one year old woke me up this morning early, I went to check my phone to see what time it was but the screen wouldn't turn on.
I left it on my nightstand with well over 50% battery when I went to sleep, no apps running like usual. My device will lose 3-4% battery over night, so no big deal at ~50% battery overnight.
Continuing with the issue, I booted the phone up to see if the battery had drained or something but it was still at 50%. After it fully booted a message popped up stating something to the fact of:
"Wondering why your phone turned off? It was turned off to rest. Your phone needs to rest to continue operating at optimum levels. Using high draining applications like navigation and video streaming can hinder system performance"
Or some kind of BS like that. I wish at 3:30am I had the forethought to screenshot the message...
Has anyone else had this happen? The thing is, I barely used my phone all day. Literally a few minutes of talking, few texts, took a few pictures and browsed a few articles using chrome.
I rely on my phone for my alarm so if this randomly happens that could be bad if my daughter sleeps in!

BTW, I'm running @santod040 stock rooted 5.0.2 full version.

Mine has done the same a few times since the OTA. I'm 100% stock

Nice when you rely on your phone for an alarm, right?

Have same problem. Has happened about 3 times since lollipop update. Fully stock. I tried cache wipe but that hasn't fixed it.

I am 100% stock as well, unrooted and S-ON. This has happened about once per week. Phone shuts down by itself and displays a message upon restart (see attached).
I've asked HTC support and they've had me try safe mode and wiping cache partition, though it sounds like it's a more widespread problem than something caused by a third-party app.

[Q] My Sprint S6 get's terrible battery life

Now.. I'm on my phone a lot normally. I text, and use FB messenger, and a lot of Google Now. Because my phone battery dies so quickly, it sits plugged in a lot, and I don't use it nearly as much as I'd like to.
If I am using my phone a lot, I can take my phone from 100% to 15% 3 times in a day.
I factory reset recently, and just let my phone sit with nothing but Google Messenger and Facebook. It still dies from a full battery in ~4-5 hours, without me touching it. Thing is, all the battery stats show less than 5% usage. And there's no crazy crap like games, etc running. I can't figure out what's eating the battery.
I just put the phone in Airplane mode, and enabled Wifi. I'm getting all my emails, fb messages, gmail, google voice, so on. Battery only went down 30% in 28 hours. I turned off airplane mode (it's not connected to Sprint at the moment, I took it off the account), and I have an Airave...battery dropped 15% in about 30 minutes. Went back to airplane mode with Wifi on, and back to a really slow drain.
Right now, I'm planning on packing up my phone tomorrow and sending it to Samsung for a battery replacement. Because my standard 2A-5V can charge this phone from 10% to 100% in an hour...which isn't right. Not the original QC2.0 charger.
Update: I turned off airplane mode again, and the phone is steadily losing 10-12% battery an hour.. and there's nothing running. It's sitting face up on my coffee table.
What can I do to stop the battery bleed? It's completely stock, on the latest update from Sprint, with no root.
I got an RMA from Samsung to send it in for a battery replacement.

Attached are screenshots of my battery stats. It just makes no sense. Even after a factory reset, not everything using the battery is reporting to that page. The sharp drops in battery are from when the phone is not in Airplane mode (only wifi on)

I've got the same issue. No better than 7-8 hours of standby time. My cpu will also heat up to 160 degrees while running very basic apps.

Any guesses on what's wrong? What have you tried?

turn off:
mobile networks > Connection optimizer
wifi > always allow scanning
these worked for me. hope helps you too.

Yes this is a battery hog for sure shut off that Connection Optimizer, also I set my screen brightness to auto (little check box after the slider) and I noticed a big difference in battery life, I use to crank up the brightness and battery would drain fast, I been on 2 days now at 79% battery..... also not sure but I shut off notifications everywhere too, I don't need facebook telling me everytime a monkey posts on another monkeys wall every 2 minutes, that helps on battery drain as well.

ditto.
This has gotten much worse since I updated to 0I1 rooted with unikernal v9
Also for some reason now... even though both the connections optimizer and wifi scanning turned 'off'-- wifi still keeps randomly turning itself "on" frequently. That with the incredibly poor battery and overheating is frustrating.

Good for you

I had the smart connection optimizer, and wifi scanning off. I also have the wifi location scanning thing turned off.
None of that helps.
My phone is on it's way back to Samsung right now to have a new battery installed.
At this point, I'm pretty sure it's faulty hardware.
