Hi all. Here's the thing. Yesterday i've charge my galaxy (up to about 90%) set up alarm for morning, and going to sleep. In morning my battery was empty, i don't have idea why, because i push power button to "sand-by" on my phone in that night. What's the deal? Stand-up time was about 7h - is there any fix for that, or maybe it's some kind of bug? Oh that was my first stand-by mode for so long time (phone is pretty brand new, about 3 days from purchase)
Few words about phone:
-i9000XXJF5
-no root, flash, and any modyfication
-in phone i have about 20 instaled apps, 4 widgets on
-no task killer
-about 3 days from purchase phone
-home screen set on LauncherPro
Any advise guys?
Sorry for my english.
There must be some app draining your battery. My SGS usually drops only 4% in battery percentage during the night (I turn of 3g at night using SwitchPro, and I'm on JM2).
Have you installed the latest Facebook for Android app? It drains battery a lot because it keeps the phone awake 100% of the time. Uninstall it, or at least Log out from within the app, so that your phone can sleep in idle mode.
Yes... the problems of Android... I use CPUMonitorMini to keep an eye if any apps go rogue and start hitting my CPU 100% and draining my battery dry.

No i don't have this app. Maybe the problem was autosynch option ON.
Prior to ICS my tf101 would last a good 3-4 days on a fully charged battery with my normal usage during the week. Yesterday I installed ICS went to sleep with just over 50%, it had suffered some heavy usage yesterday, and woke up to a completely flat and switched off tablet this morning. This is very unusual performance for my tab.
When I installed ICS I did a factory reset to clean up my tab so only have a pinch of the apps I had previously installed. One thing I did notice is on the battery tab of system settings the tablet was awake 100% of the time were traditionally it would only have a blue mark were it was in use on the awake line. Battery usage data is unavailable, too, so cant see what is causing tablet not to sleep.
Any suggestions?
I would wait until it settles a bit more, plus wait for a custom rom. It probably has some bug, seeing as it is the first ICS for our device.
I also notice some battery drain last week
on HC and ICS
right now i reverted back to honeycomb
ill update you later
if anything changes to me
MyZine Widget
Got rid of the MyZine widget and my tablet now goes to sleep in standby. I noticed, when browsing the running apps list, that the app kept 'restarting' so it could buggy or at the least was having a problem with my tab.
Prior to ICS my battery drain was crazy, especially if I leave wifi on. Not anymore, it's back to normal consumption like I had before the last HC firmware update.
I had the same problem this morning.
take cpu spy to have a look if the tablet goes into depp sleep.

i had to reboot and then everything was fine...
I've still got problems with my tab. Returned to it after a few hours non-use and it had shutdown itself. Battery Drain still seems an issue too. I'll install that app and see what it reports.
Check WiFi disconnection policy and if GPS is disbled.
Here I am trying to get answers to exactly the op's problem. Everything went smooth installing ics. Even wiped data.
Woke up this morning to a very dead battery. Went to sleep at 83%. Interestingly, the battery graph show nothing after about 80%. No indication on the graph of total discharge...and no app usage. Just straight from 80 to zero.
I can't determine if it's a hung app or what....I've installed almost nothing. And it looks like the tablet drained while it was OFF!

Sorry for the link....I could not get the damn picture posted for the life of me...despite 45 minutes worth of my time.
i also woke up to a dead battery this morning. it was 50%+ when i left it on standby, wifi & gps switched off. i would have expected minimal drain on HC.

Try this
Go to settings /WiFi /click three dots in upper right corner/Advanced/ uncheck keep wifi on during sleep.
go to recently used apps and close all ( swipe to right)
put tab to sleep for a while
Come back and turn on.
go to settings
battery
tap grey battery level graph to expand
check individual bars to see what was on and off.
Looks liks some apps are keepi9ng WiFi and GPS on and draining battery.
It would be really nice in future update to have a setting like below:
Setting
Sleep setting
On screen off close all apps except ( here you get to choose apps to leave open)
I'm glad I am not the only one with battery drain issues. I thought I was doing something wrong.
Several days ago I charged my dock and tablet fully. I then turned off the tablet, closed the lid and didn't use it for a few days, when I went to run it again it was totally dead. I would have expected it to at least hold something of a charge in a completely off state.
Yesterday I left the tablet and dock on but just turned the screen off and again this morning had a drained dock.
Just seems like no matter how I try to settle on a way I still see more of a drain than I would have expected.

I will have to take a look at that setting myself and see what is up with it.
Yes, it would nice to have a sleep setting button for some helpful settings.
Have there been any firmware updates for the dock itself, or is that not possible?
I'm having the same issue dock was at 80% last night get up this morning and it's at 6%. I set wifi to off during sleep to see if that helps any.

Have to close apps that are keeping stuff on. Look at permissions. More and more are adding "prevent "Function X off during sleep."
As soon as I got the update installed I turned GPS off and set WiFi to never sleep, woke up this morning to only 4% battery drain. The tablet went 12 hours and went from 40% to 36%, i also had apps open...
apps open: engadget, camera, browser, gmail, market and settings..
no battery drain yet, updated yesterday and only 5% drain during the night with apps open
Help!
Same problem here. I noticed high battery drain yesterday and didn't think to leave it plugged in.
This morning, it wouldn't turn back on! I've left it plugged in in case the battery drained too far and will try to turn it on later on.
With HC, the power button was buggy (had to press really hard) and seemed that that went away with ICS (well except for now). Don't know if this is related.
Same issues with me. Except my tablet won't wake up when I push the power button. I have to hold and reset it. Here is the kicker: I will get a 20% power drain over 9 hours on top of it. So not only does my tablet not turn on after it being asleep, but I get a power drain as well!
My Settings: Stock ICS off a completely reformatted device, Keep Wi-Fi on only when plugged in, screen timeout is 1 minute and MobileDock Battery Saving mode is on. My battery usage indicator does not work... I have to get the very basic info from my battery widget.
Very disappointed! This was the one thing I wanted fixed the most. I hated using the airplane mode app. It severely affected performance.

Maybe we are all having the random reboot problem.
It makes sense if you think about it.. Mine would randomly go into reboot in sleep and the device would get stuck on the Asus loading screen. So when the device cycle through the loading screen for an entire night, you would find a dead tablet by the morning.
So far, I have encountered 2 random reboots, the only way to bring the device out of the boot screen is to hard reset it by holding down the power button.

balor you most likely got better battery due to custom rom
custom roms tweaked the battery for couple days use.. asus claimed like 9 hours on the tablet.. and like 19 with dock keyboard. custom ics roms inc
I never fixed my SOD problem on my TF101. I'm running AOKP Milestone 6 and Guevor's Kernel-ICS-V23-OC1700-fb-AOKP_690
I initially just used that Wakelock app to prevent it from going into deep sleep, but I was highly dissatisfied with the battery life.
What I started doing now is using this app: https://play.google.com/store/apps/details?id=com.easy.battery.saver&hl=en
I found that my TF101 does fine when it goes into deep sleep, but not if it's deep sleep for too long of a time period. With the battery saver app, I have it customized so that when the screen is off, the wifi will turn off as well. The trick is also setting it up so that the wifi will enable wifi again every fifteen minutes for thirty seconds. That brings the TF101 out of deep sleep for a little bit, lets it sync gmail/FB/etc., and then go back to deep sleep.
The benefit of this is that it prevents SOD while still maintaining decent battery life by allowing your TF101 to at least go into deep sleep once in a while instead of keeping it awake 24/7. I tried playing around with 30 minute intervals for the wifi turning on/off but I had a SOD. 15 minutes seems to be working!
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)

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

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.
ok... to save even more battery life. Get "Deep Sleep battery saver"
I have a smartphone connected 100% of the time to get all my notifications.
I only use my Note8 for reading and play. There is no reason it needs to be getting notifications of emails, texts, news, social media.. unless I wake it up to use.
after I did the battery disconnect tip. it went from 1.5hrs WAKE time to more than 5 hrs.
http://forum.xda-developers.com/showthread.php?t=2274678
but.. even when sleeping.. it would drain about 1-2% battery per hr sleeping.
android and system processes! and media updates.
so I found this app called: "Deep Sleep battery saver".
when the screen is off.. it turns everything off.. all connections.
allows NO updates.
you can set it up .. to wake up for 1 minute every hr.. or 2 hrs.. or 4 hrs. l selected "no waking up".
when the screen comes back on.. it lets the tablet get updates. normally there are none, because I have already taken care of them via the smartphone.
now the Note8 sleeps .. and only uses about 1% every 3 to 4 hrs.
I estimate about 10% per day lost if left alone sleeping.
I think if I left the tablet alone for a week.. it would still have a charge!

OK, doesn't setting airplane mode or disable sync with Wifi on when charging keep good battery run times. I don't use apps for power save, just config what is available to get great sleep power savings. When sleeping I can get 0% used in 19 hours.
that is what you would think.
but android tries to do things in the background.
it aint the apps..
android processes. eating time and battery.

i beg to differ... its all about apps. i try to run browser over using email apps. Many of the apps you get have analytics or some method to do background data. youtube, google music, weather, and briefing wil drain your battery, not Android.
to combat apps, use greenify... my main use for it is to keep my memory clean. having it save battery power was a bonus.
i agree.. generally.
my Note3 sleeps fine.. and does NOT abuse the battery while sleeping.
the Note8 does not sleep quietly. Now, with Deep Sleep.. it is great.
