running the sgh-i727r.
had the phone since boxing day and this was the first time it happened. went to sleep with about 70%, slept for 6 hours and then woke up to a turned off phone. turned it back on and battery showed a huge drop from when it turned itself off, shortly before i woke up.
the only battery saving app i have is juice defender, on balanced profile.
any ideas?
thanks in advance.
Download betterbatterystats from the market and find out what is using your battery...
Are you rooted? if so.. reboot into recovery and erase battery stats and calibrate your battery..
More then likely have an app running..

On a four hour flight this past weekend, I shut my stock 1.12.605.6 ThunderBolt off completely by holding the power button, then selecting "Power off". The battery level was at 68% at the time. When I landed and booted back up, my battery was at 17%. That's a 51% drop over a four hour period with the phone powered off.
To test it further, on the way back, I set the phone to airplane mode. The battery was at 71%. At the end of the four hour flight, I powered up the screen to see that the battery was at 68%. That's a 3% drop over a four hour period with the phone powered on, but all the radios (and the screen) off.
Has anyone experienced this?
That is strange. Have you reset the battery stats?

That's weird. Turning on/restarting your phone drains some battery, but not that much... I'd just leave my phone on airplane mode...

You need to clear battery stats or condition you battery with bump charges....when I first got my phone I charged it to 100% then unplugged it and immediately rebooted and it dropped to 78%. The batts are just weird imo

It didn't actually drop that much. It wasn't reporting the battery % right. Either before or after the reboot.

Hey guys, I thought I was getting decent battery life until I noticed that if I charge my phone and leave it unplugged overnight, I get severe battery drain.
Last night, for instance, I went to sleep at 12am with 97% battery and woke up at 8:30am with 65%. I had WiFi on overnight because I figured LTE drained more, but my battery use screen is showing that WiFi was cut off shortly after I went to sleep. However I also have noticed other times that I lose 15-20% overnight with data completely off.
I don't think it is a rogue app or anything because I am using the same ~30 apps I have always used and I have never had a problem with any of them. I am coming off a fresh install of CleanROM 2.2, but I have noticed this issue with every build I've used since getting my HOX.
I also noticed that its saying my display is taking up nearly 50% of my battery so far on this cycle, when its only been on for a total of 30 minutes and its been off the entire night.
Are there any apps that will help me figure out what's causing the drain?
Better battery stats check xda it's free and look at partial wakelocks

Want to see bad overnight drainage?
I woke up to a dead phone and this...
Try this:
Charge to 100%
Boot to Recovery
Wipe Data
Delete Battery Stats
Reinstall CleanROM (I'd suggest upgrading to 3.0)
Restart
Run Battery down without shutting off
Recharge
After you recharge, it should be fine. If not, return to stock and try to get it exchanged because it is defective. Just hope the people at AT&T don't check the bootloader, and you should be good.
overnight battery drain and warm.
I've been experiencing the same issue.
Two nights ago I went to sleep with around 73% and woke up with 71% and last night, I went to sleep with full charge, wifi and data off, and woke up to 77%.
Is your device also exceedingly warm?
I've also noticed a few times that it will give an inaccurate charge percentage, until a restart sometimes. So for example, it will read 65% and after a restart, it will read 95%.
I saw a post somewhere about htc smartsync causing some issues. Maybe it could be the cause of this drain? Apparently it shuts off wifi and data between 1 and 7am and only turns them back on to sync at certain intervals. Also it's buggy as hell so it just f's everything up. I'll post the link to the relevant thread once I find it.
Edit: Found it http://forum.xda-developers.com/showthread.php?t=1708492
I took the phone of the charger at 7am this morning, it had the green LED on and said 100% so it was charged. I sat it on the window cill and never looked at it, Went out at 11am and checked the phone at 11.30 it said 4% and had a critically low warning. I said this can't be right, rebooted the phone thinking battery readings must be wrong, it restarted at 2% and then turned off.
Now what the hell could of caused this, I am using an Anker battery less than a month old. I have noticed in the past if I leave an app open such as a twitter client and lock the phone without closing the app it doesn't sleep like it should and eats battery, and this is what I did this AM, checked twitter, locked the phone took it of the charger and thought no more about it.
So the question is why when I lock the phone do apps not sleep like they should? Auto sync is off etc, and secondly when I connect this phone to a charger how exactly do I find what killed my battery the last time?
I should add although this is an exteme example without putting my phone in airplane mode half the day I will not make it through the day which is pretty dire for a phone.
Ok I have found out my stats, I challenge anyone to beat this.
3hrs 34min on battery with 2 mins screen on time and I was flat.
Android OS 72% is the battery killer. Phone is obviously not sleeping. Anyone any ideas?
If I play games on airplane mode and on lowest brightness, my battery lasts 1 hour. It's the original battery and I'm going to buy a new one soon

Greetings:
I am just wondering if my new note pro battery discharges normally.
The tablet is left at 91% at 10:00 pm yesterday. Nothing is running in the background, Power saver is on, screen brightness about 25%, only wifi is on, multi windows is off, all sounds setting off, haptic feedback off, push notification is off, it is down to 76% this morning at 6:00 am. Without using it for 8 hours, it loses 15% charge. The battery usage shows that the screen uses 47%, android system 14%, and android OS 11%. I ask the amazon online community and some users report that their tablet loses only 9% charge without using it for two weeks. Is my unit defective?
Thanks in advance for your time and help.
You've got an app causing a wakelock. Reboot. Put it in Airplane mode tonight to see if results are better. I lose maybe 1 or 2% overnight when I use airplane mode.
Mine drains at 0,2%/h according to BBS. So no, yours is probably not discharging normally.
If you're rooted try Wakelock detector. If you're not, try BetterBatteryStats. Both can be found here on XDA
Thank you all for your help.
After turning off many running app which i didn't launch, set auto brightness to on, the tablet seems to hold the charge now.
According to the battery usage screen, about 15% of the battery has been used. And yet, it's in freefall. At 34% I got a low battery warning saying the battery would only last another three hours, even though it was dropping about 1% a minute.
Just randomly happened today. Left it unplugged overnight with Sleep as Android running, woke up to about 70% battery, started browsing on Chrome and Talon for Twitter, and 15 minutes later I had 20% battery. Plugged it in, got it back up to 75%, had to go out. Felt it get hot, checked, saw it was still dropping dramatically. Turned it off, left it to cool, turned it back on, and it continued dropping.
I had it turned off for a while to cool down after I'd plugged it in, as well.
Battery Usage does list Sleep as using 22% battery, but that's since the last full charge so I assume includes what it did overnight, which jives with having a percentage in the 70s when I awoke. Talon, Chrome, Facebook, TiBu, and a couple of other apps are listed as using 1-2% of the battery. That's it.
WTF is going on?

I think the battery might need to be replaced...after I charged my phone to 100% and then reboot, it will show 69% or 70% after the reboot -_-|. Also when the battery % drops down below 50%, my phone could switch off anytime - and then when I switch it on again, the battery is like 1%. I am using this phone as a backup just to receive messages so I don't mind it too much. If you use it as a main phone maybe it is time to upgrade to a newer model...the battery on regular Pixels were not so good even when new...
When the phone is off charge it to 100% then use it until it dies completly, then try to start it couple of times(it should just show a battery low icon or turn off while booting). Then charge it to 100% again while turned off.
This should pretty much reset the electronics in the phone. If it still does it replace the battery.
P.S.: Also look at the phone from the sides to see if you notice any glass poping (just in case the battery has started to expand)
