I charge my phone to 100% before bed, turn off the sync, and don't use it at all overnight. I'll wake up in the morning and it's drained down 15% or so without touching it. When I check my battery usage, it shows that about 4-5 hours after unplugging it, something wakes up the phone and keeps it awake causing a dip in the battery level. There aren't any apps that are doing it as the main battery user is the Android System.
Now, if I reboot the phone while still on the charger before bed and allow the phone to return to 100%, this drain doesn't happen. I'll wake up and have 95-97% battery.
Any help or ideas?
BTW: I'm running Calkulins ROM 2.8 with and EL29 but this has happened since before I rooted the phone.
Download betterbatterystats from the market. Let the phone sit overnight again and view partial wakelocks.
Or turn the phone's airplane mode on...
I'll try the app. I can't really use airplane mode because I need to phone on for emergencies. Thanks.

If you don't need data, you can turn that off along with sync. Calls will still come through

Couldn't convince the phone to swallow the pill.
I figured it out with that app. Slacker Radio was the problem. I used the it during the day and didn't exit out from the app. I guess Android killed the process because it was idle for so long because it wasn't coming up in the Active Applications app but it was still active in the background. The app mentioned earlier showed me that Slacker was active for over 2 hours while the phone was sitting, screen off, overnight. That's why when I rebooted before bed, the drain didn't happen. I just have to make sure to exit out and close the app when I'm done with it. Thanks for the help.
Even exiting the app via the in app menu causes the problem. The only thing I've found to completely fix it is to either reboot the phone sometime after using the app or clearing the RAM via the included task manager. I sent an email to Slacker support and they told me to use the app menu to exit out, well that doesn't fix it. Hopefully it'll be addressed in a future update from them.

Are you running stock Rom? I suggest using an SBC kernel..
more info needed what programs have you added. something maybe causing a wake lock issue.
rooted my new EVO with unrevoked3,then installed netarchy-toastmod 4.3.1 kernel and my battery lasts all day with moderate usage
I doubt rooting it made your battery worse. there are many rom choices and apps to help you out. With rooting comes tinkering and it looks like its time to tinker. Look into an app called Spare Parts and another one call Autostarts

Cheers!
The other issue is your battery stats may be off if you did something odd during rooting. There are several ways to fix that, the generally accepted way is to charge the phone while its on, turn it off completly, then:
1: Unplug phone when light is green
2: Plug in the phone
3: Repeat 10-15 times
I had the same issue, and this is what I did to fix my battery.
1. let the phone die completely, IE when the phone cannot turn on at all anymore.
2.Leave the phone off, let it charge overnight.
3.Verify that the phone is at 100% by going into settings->about phone->status
4.Power the phone off.
5.Boot into recovery
6.Wipe battery stats.
This should fix the issue, if not then consider using a different rom/kernel combo. I myself am personally using CM7 and suffer maybe 40% drain at most with my phone in my pocket with a typical 12 hour shift at work.
**Also, turn 3G off if you aren't using the internet, facebook, or Gmail ect ect. You can still recieve phone calls and text messages using this method. I believe there used to be an option to only have 3G running when the screen is on but i'm not 100% sure if this is still available.**
Yeah like I did that crazy charge thing I read about where you let It die and it helped for a bit and now thing just goes down like 20% after 30mins of just sitting in my pocket

What could possibly cause battery tl go down 25% in 8 hours while in airplane mode screen turned off???
I used autostarts to stop anything from starting up on its own. If this is a bad idea what should I re-enable?
I looked in spare parts and battery usage but I can't really make sense of it. Thanks!
25% in 8 hours is pretty darn good. Besides, isn't the autostart app using power to constantly stop apps from automatically starting?

I don't know what autostart is but I think it may be the problem.
I think something is wrong. I don't lose that much when I go into airplane mode.
Edit: OP, check spare parts for partial wake usage and see if there are any rogue apps.
If my phone was in airplane mode with screen off for 8 hours, I wouldn't lose more than 5 %. Hell, I only lose 5% with screen off over 8 hours, even with my radios on.
If he was using it, that's way different, but I picture "airplane mode with screen off for 8 hours" to be like if the phone was idle on the night stand, during a night of sleep. In that case, 25% is excessive, IMO. Autostart would be my first thought, I'd ditch it.

No need to apologize man! You're on here helping so much, I bet you got googly eyed and simply missed it I was just stating how I'd expect my device to act in the same situation, and also my two cents!

FYI I had a more extreme version of this happen to me on an airplane. Battery started dropping at like 1% every 20-30 seconds after enabling airplane mode. I killed every task I could find and it stopped. Seems like it's caused by an app that isn't checking for airplane mode before trying to make a connection. Never figured out what app it was but something similar could be causing the problem here.
Re-enable everything in autostarts and delete the app. Boot into recovery and wipe your battery stats, cache, and dalvik-cache. Turn off the phone and take the battery out for like 5-10 minutes and leave it somewhere without heat, like a dark closet. Put the battery back in and boot up the phone, turn on airplane mode and see if it does the same thing.
so you guys think autostarts could be causing the problem? from the way I understood the application, it does not run in the background - just modifies entries in the android system to avoid triggers calling programs.
That said thanks for the suggestion and I will try it out!
Also did you just flash it, because if you did you should wipe your cache, dalvik-cache, and battery stats. Then recalibrate your battery.

Its like re-energizing your battery so to speak. Go to the market and download the "Battery Calibration" app. Follow the steps in the app and it does it for you.
So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex

Clearfi.apk
DTG.apk

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.
Sent from my MB860 using XDA App
here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

So im on stock rom jellybean unrooted, i dont sync anything its turned off i update stuff as i use it like facebook, email etc.Im sure if you check i won be the only one having this issue .The other night i was night shift and as phone signal is very poor in areas i work i often put my phone in airplane mode to save the battery.I did this the other night and noticed as soon i cam out of AP mode and started to use the phone the battery lost about 10% in the space of 5/10 mins.So i lookeed at battery useage.
You can seen from the first pic the screen was off and and wifi/network disabled yet something kept the phone awake.In the second shot it happens again later on in the morning,and during the time the phone appears to wake randomly even though screen is off etc
So last night put the phone on charge over night and when i took it off charge same thin happened battey dropped alot, this time screen was off but wifi/network on see pic 3 , it randomly wakes and sleeps
any ideas how to stop this as its draining my battery massively

Keep wifi enabled, that may reveal some apps that keep phone awake by syncing.
I have a similar problem. An analysis with BetterBatteryStats showed that what keeps my phone awake most of the time is
GTALK_ASYNC_CONN_com.google.android.gsf.gtalkservice.AndroidEndPoint

Unfortunately, I haven't found yet a way to solve the problem.
Google now is off, gtalk is offline, location reporting is off, Play store updates is off, Admob is off.
As you, I sync almost everything manually. That wakelock is there even if I turn off autosync.
The last thing I tried was resetting to factory defaults. That wakelock was there even without inserting my google account.
So, long story short: I wish you that your problem is not GTALK_ASYNC_CONN. Otherwise it will drive you crazy.

Anyone notice problems with the NY Times app recently? I noticed some high network activity out of my Note Pro over the last few days, and dug into it last night. Turned out, my tablet never went to deep sleep, and looking at battery usage, the NY Times app was behind only the OS and System.
I can't uninstall the NY Times, but I can revert to the factory image, and that seems to have put a halt to the network activity, and also the tablet is now going into deep sleep again. So it looks like it was an app update, somewhere along the way?
What's deep sleep as opposed to sleep as opposed to going into airplane mode?? Your posting about the ny times and sleep is difficult to understand.

Not difficult to understand at all, this is apparently a wake lock issue with the application.
Tapping the power button to turn off the screen puts the device in sleep mode but CPU speed still varies as background activity continues. Application processes can place wake locks on the CPU to keep it from going into deep sleep which is the lowest power consumption setting. A device that never goes into deep sleep will experience higher battery drain with the screen off for extended periods than one that does go into deep sleep. Sleep has nothing to do with airplane mode, which turns off all radios and has no direct impact on CPU.
First thing I would try with the NY Times app is turn off all notifications for it. Personally I don't use it and have it frozen so I can't verify the wake lock issue on my device.

Much better explanation than I could have given, thanks! So wish I could root my tablet (a Verizon...), feel like I'm trying to debug things with both hands tied behind my back!
So far, the NYT problem hasn't come back - can't freeze or uninstall it without root, but have removed it from Magazine UI and basically backed out all updates by restoring it to its factory image and clearing its data. BTW, it was set to only get updates every 4 hours. Obviously it had a different idea.
Yeah I hate it when apps get like that.
It's times like that where I'll use Greenify sparingly to push the misbehaving app into hibernation. Otherwise I'll just let android do it's thing.
A few days ago, I noticed the NY Times app only it's you view 10 articles for free every month. I was going to say, why not trash that garbage? It requires root, though, since it's actually a system app. That is just profoundly stupid.
At least Samsung didn't pick CNN as it's news app, amirite?
