Wondering what everyone's overnight battery drain is looking like. picked up mine on launch day and the first nights battery drain was only 9% but last nights battery drain was 27% i don't know if it was something i had running in the background or what. Wifi was also on both nights.
I've seen this type of issue but have not been able to pinpoint the true source of that big drain when its in sleep mode

Applications. I'm sure of it.
I'm having the same exact issue.
Last night I went to bed with 11% and I woke up with 9% (7 hours of sleep).
The secret to almost 0 battery drain on your phone at night is to use juice defender + airplane mode. I set my juice defender's "night mode" for 1am - 6am, but you can mix that up based on your sleep schedule. Juice defender will disable data during that time.
I turn on airplane mode at night because nobody is going to be calling me when I'm sleeping. The only person that would is my fiance, and she sleeps next to me.
Juice defender almost helps battery life throughout the day. Also, make sure battery saving mode is checked under "display and sound settings." I've been experiencing phenomenal battery life so far. My 2nd charge went for 21 hours with 4 hours of screen on time.
I hope this helps

yea i just started using juice defender got the paid version this morning so we will see how it goes tonight. i also have advanced task killer now which will kill no essential apps/functions when i turn the screen off. Hopefully battery life increases over my old palm pre lol. It's also doesn't help that at work i only get 0-2 bars inside so that kinda sucks my battery life down alot.

Hmm.. Must be what is happening to me. I always have 2 bars where I live.
i've got to wonder if inaccurate battery level reporting isn't part of the issue, and i don't just mean the battery icon in the top notification bar
some other posters have remarked how much life they had even after the low battery warning notification popped up. http://forum.xda-developers.com/showthread.php?t=770207
after the first few weeks of use, once my battery had settle down, i was seeing 1-2% drain at night after taking mine off the charger at 11:00PM
i even took to putting it in airplane mode & turning off GPS - and it didn't affect the 1-2% drain
but every odd day it'll show 8 to 11% drain after a full charge and putting it to sleep at 11:00PM
the same with the radio signal strength indication given in settings - again, not the signal strength bars in the notification. When my signal strength is showing 0 & 0 asus, i can still make calls with no drop outs etc
look I understand and agree that juice defender and airplane mode help but lets be honest here
not all of us want to disable the phone to save battery. standby should not take this much battery even without the damn defender and schmender
something is going on thats draining battery
my evo did not do this at all even without defender or airplane mode

This is true. Once the battery hits low levels, it must kick into super battery saver mode because it hangs in there like a champ. I was trying to murder the last of my battery so I could completely drain it all the way. At 6% I just loaded up a movie because that's a good battery drainer. It took an hour to hit 0%, and even then it didn't shut off.

Huh. I found that my EVO drained more battery life when idle than my Epic. Cell standby will kill your phone when idle if you don't have great signal. This is the reason behind airplane mode. Task killers will also drain your battery. Anything that runs in the background, really.
I'm running systempanel to monitor eerything and I noticed that the phones cpu is at 30% when sleeping with occasional spikes every few hours to 100%.
I also run tasker, and then both run in background...

I just worked this morning from 10pm to 7:30am. Night shift at Wal-Mart. Went to work with 96% and ran Pandora all night, facebook, texting, net on breaks. Got home at 12%. About 10 hours of good use. I can live with that. But that's an example there.

Anyone know what could be the cause of my battery dying while I'm asleep at night? I don't put it on the charger at night if the battery is above 20% and the last couple nights my battery will be near 30% and when I wake up in the morning it's dead?! My feeds are set to update 12 hours apart which is usually around 7am, and I thought it was the auto task killer but I shut that off. The only thing I can think of is my alarm?! But really? Any suggestions?
Using 2x push accounts (Gmail and Exchange) I will lose 2-3% per hour when in standby (over night). This seems consistent with what I saw on previous HTC Devices (6800 was worse, TP and TP2 were about the same).
If you are in a good coverage area with no push and are seeing higher drain than that I would check and see if the phone is either being prevented from sleeping or see what is using the battery in the battery info.
Ye, my battery just went from 48% to 3% in about 3 minutes. Does anyone have any idea why this is?
Same problem here. From about 43 % down to 7 % while it started to charge the battery with the original charger. Afterwards the Tab didn´t charge at all. Battery drained and got very warm.
I Called Vodafone and was told i have to send the Tab in for fixing. I hate waiting for the tablet 3 weeks.
Update: After 2 hrs. of waiting the Tab cooled down and i was able to start it again. Did a factory reset and was able to charge again with the wall mount charger.
Just wanted to bump this as my battery life is miserable and it discharges really fast in standby...
My HTC desire has been on for 52 hours, used for a lot of stuff and is at 20% battery.
The Tab charges to 100%, I unplug it at night and in the morning it has lost approx 10%, I leave it a few more hours and it't down to around 60%. This is with no use and no apps running!
I've tried killing apps or leaving them in memory and it doesn't seem to make much difference. I also use setcpu and have a profile where the CPU speed decreases when in standby to conserve battery?!
If I charge to 100% and use it constantly, I get fair life out of it maybe 4-6 hours of light use - some streaming over wifi, web surfing, kindle, sudoku etc. If I use it occasionally or heavily though, it dies very quick and if I leave it at about 40% on the evening, it's generally dead in the morning.
Why does it discharge so fast in standby??
Check to see if it continually searching for a signal. I've noticed that mine loses a lot of power constantly searching for a signal, cellular and wifi. So, I used airplane mode to conserve power. Remember that it syncs to different services that require it to periodically download data. That may be your issue.

Thanks Chuck, I use it in airplane mode all the time and only use web over wifi (bought unconnected in the UK). Would it still be syncing for email etc? I didn't think it could turn on wifi and sync itself but only when I turn wifi on. I always turn wifi off when not in use. I had problems with widgetlocker asking for superuser permission quite often and that killed the battery quicker so I removed that until it's fixed and saw an improvement.
I'm not seeing the times that other people are though, losing at least 10% overnight and there's nothing really running.
I installed battery doctor and the times it quotes are high for different types of usage and nowhere near what I'm getting.
I'll make sure email and calendar are set to manual update, adjust brightness etc and see what happens. It seemed better when I first got it so perhaps an app is draining it? I installed system panel to monitor this but it's hard to see what is actually draining it, any recommendations anyone???
Quite disappointed at the moment, ipads barely drop 1% overnight and I'd rather not have to turn it off to conserve battery when it should maintain it in standby...
Check the task manager and see what application are running. Also you can go in settings- about device - battery use to see if a specific application is using your battery out of normal. Also , the display is generally the battery hog, you may have set it to a super high level. One last thing you may have the buggy 3d gallery app, and it will show in the battery usage.
P_
this is an interesting problem. its very similar to the Apple Macbook Air.
The Macbook Air was very thin - very nice looking - however it needed to depend on wifi to do most things.
the association i am trying to build here is this: the Tab needs a bluethooth headset so you dont get all your calls broad-casted over speakers and that could drain the battery a lot.
for me the battery drainage didnt seem so bad and its been on for the last 36 or so hours. the battery icon didnt look like it moved so much and i was impressed considering this thing had a gigantic battery. then i loaded up a utility that read the battery and said i had 59% so my jaw dropped. not only is the battery indicator wrong there maybe rogue processes casuing the battery drainage. and this is on 2.2 which is supposed to be somewhat battery efficient.
i dont know - frustration is what i am all about here with this thing. it seems that every time i buy a new android device i want to move to another android device. no one is getting the damn thing correctly setup.
Am at work right Now, Charged the tab overnight, just few minutes ago my battery said 60% left and now the tab is completely dead, wont turn on, I ll wait until i get home to charge, fingers crossed.

I am experiencing the same thing. Tab on flight mode and charged to 100% overnight. Unplugged at 9am, still on flight mode with no apps running, and it is 88% at 2pm.
12% drop in 5 hours with no usage whatsoever is way too much imo, comparing let say to my HD2, even not in flight mode. Wonder if they have a bad batch of battery for certain tabs........
Just wanna report back after my last post. When the percentage was dropped to 85%, I did a reboot. And guess what, now it displays 95% !!!!!!
5% drop from the morning til now in flight mode seems right and okay. Does it mean the tab is miscalculating the percent left?
PS.
I have been following the voltage in Spare parts this morning. All settings are the same (no apps opened, same screen brightness and in flight mode. Only turn on to record voltage)
94% - 4087mV
91% - 4081mV
88% - 4075mV
85% - 4067mV
But then after the reboot
95% - 4040mV
Man, I am not sure whats going on here........

let me jump in here again and share a similar deli-ma i had with my X10i.
while i was messing around with some custom roms i decided to stick to one that looked somewhat nice. well the funny thing is the battery indicator would always display 100% and for about 4 hours it would drop ever so slightly. then i removed the battery and put it back in -- the battery indicator showed 0% and i got a red light flashing ....
after screwing around with it for a bit i re-flashed the stock firmware from Sony-Ericsson and magically my battery meter and my battery worked fine.
so to sum up -- it maybe a software issue like the one i had on my SE X10i above?
I'm quite staggered to state that my S3 haven't used a single % of battery overnight, I left my phone at 66% and in morning my jaw just dropped by looking at battery meter it was at 66% i thought it was stuck or hanged so i restarted my phone pulled the battery out and waited for 5 mins and turned it on again and voila it was at 65%(1% lost due to booting)
also my S3 is Made In Vietnam
Isn't this a good thing? Phones don't really use a lot of power when on idle like this. As long as u have a good signal and the radios not trying to pick a signal the battery doesn't drain much. I've left my g2 overnight several times and it hasn't gone down either
Sent from my HTC Vision using XDA
Yes its a good thing however my last droid eats 15-20 % battery in night which is bad.
Auto-sync on? 3G/wifi/airplane mode? Wouldn't mind having tiny idle drain myself
Phone is set on 2G network(not on Airplane mode) with wifi and auto sync OFF
I also noticed my SGS3 drains very little at night. However, when idling at daytime it does drain more battery (using System Panel to monitor battery levels).
Perhaps there is some power saving feature that put the phone in a deeper sleep-mode at night? Automatically disabling auto-sync etc?
Closed, we have a thread right here for initial reviews/discussion.
Thank you.
I have Problem With Standby Time .....My Battery After 12 Hours Standby Have 50% Drop.....I install Stock Rom But Itsnt Fix...Please Help Me:crying:
( I do wipe cash and wipe battey and calibrate)
new ugsrii
how long your battery used? if >2-year heavy use, could well be battery degrade. no solution except for buying a new one. (symptom: battery charge sudden drop, like 50% -> 20%).

For me battery drops can sometimes happen when I don't charge battery to 100% - so it's good idea to always charge to full.
First of all you should check if your battery is going into deep sleep mode. You can do that by installing Bettery Battery Stats, and leaving your phone idle with the screen off for some time. You should read the forum post to understand how it works. If after leaving your phone on "stand-by" you realize that it's not going into Deep Sleep mode, then you should find out what is keeping your phone awake.
I used to have the same situation as you, and it turned out that I had set the WiFi Sleep Policy in Viber to override the Roms setting, and consequently leaving my WiFi always on (which prevents your phone from sleeping). After fixing the issue in Viber my phone now turns WiFi off after 15 minutes of leaving my phone idle.
Now unless your battery is actually dying on you, I'm sure you can get a better battery life. I am using Tasker to program my phone to turn WiFi off when I turn off my screen, and then turn it on for 1 minute every 15 minutes during the day, and at nights it does the same thing but with an interval of 1 hour and half. There are apps in the Play Store that do this too, I've tried these both, and they work as they should, and they can even control your Data connection
Green power
Deep Sleep Battery Saver
All in all I've been losing an average of 1.7% during the day, and 0.7% and 1.2% per night. My battery currently lasts about 2 days on one charge. This is all assuming it is actually your WiFi that's preventing your phone from sleeping, I just figured I'd share my experience in case it is in fact that; the important thing being that you could probably get the same results as I have (or even better, considering your battery isn't busted) if your phone is actually going into Deep Sleep.
Hi
Brand new phone here, not rooted and fully stock.
During last three days I noticed a huge battery drain overnight, so I installed Better Battery Stats. Being not rooted I don't see many info but one thing is clear: after 6h being idle, I have lost 17% and BBS shows one single line as per attached screenshot.
Any idea what's going on?
Thanks
try turning off wifi and anything that syncs constantly. go into settings, battery and see what it shows. no need for an extra app.
????
I don't want to turn off wifi at night.
With my edge+ all was remaining on and I would use only 4% overnight
I have the same problem. Go to sleep at night and wake up 7 hours later with 40% drain during the night. I don't use wifi.

I've had this phone for a week, and the first 3 days all was ok, but during the last 3 nights I am experiencing this huge drain overnight.
Problem is I am not rooted (and am not willing to root right now, till Android N comes) so I cannot really use wakelock detectors to see what's going on.
Phone is set up exactly like my Samsung S6 Edge+ and this one drain max 5% overnight.
Again go into settings and battery and see what is being used
Ok tonight I'll check
Here it is.
Unplugged and left 6h idle overnight with wifi on.
Lost 12℅
I cannot understand what's going on

Please note this happens only at night while phone is idle.
During day battery seems OK and wifi or idle do not show up in battery usage.
Also from the screenshot I see only 1% and a very low mA usage, so I don't understand why I lose so much battery when nothing is going on.
Is this really a problem? Your phone is losing between 2% and 3.3% per hour. That doesn't seem that bad. Mine is around 6% during the day (I have it plugged in during the night).
2% per hour in doze at night is a huge problem

Yeah, that kind of drain is an issue. I lose like 1% every 6 or 7 hours overnight with phone in doze with 2 maint. cycles
