Battery Drain overnight

I don't know what is wrong with me (I know this is something I'm doing wrong), this happens EVERY time I have an android phone.
I think I'm not closing an app or something and the battery drained overnight, it happened when I had a G1 and an X10... Anyone experienced that?
Is there a way to close apps properly on Android? I don't want to have to install something to manage whether my apps are open or close, I just want them to close when I'm done with them....

Internet.. guessing you dont use it at night so try this.. 2 methods of doing the same thing 1) +/Widgets/Settings/Mobile Network and just toggle that whenever you don't need to use 3g connection, or before you go to bed. 2) Hold Power Button/ Mobile Network and make sure it says Connet to Internet is OFF..
for me, this gives 3 days of battery (also doing some under clocking at night ) loving the phone!

Ive experienced high battery usage on a HTC Desire, a Google nexus one and now on a Samsung Captivate. It always seems to be Android OS and the usage is even higher than display which is ridiculous.
It happens on and off and its really quite annoying. I always think Ive found out what causes it...and then it happens again!

I have to ask the question, but have you regularly been using the same 3rd party applications with each of the phones?

Dave

I realize the logic behind the question you're asking. Ive noticed android os battery drain without any apps installed (i.e. stock only). It doesnt seem to happen on a regular basis though.
At one time, I was pretty confident it was a generic charger, another time after usb connections and even something associated with google push services.
Not really sure what it could be. Its like those experiments at university where there are way too many variables, so the only option is to sit down and data log until a trend emerges. Frankly, its a phone and its too much time to actually sit down and do that. (Yes I know im lazy )

2-4% battery drain is normal at night, if you have airplane mode on or at least 3G / WiFi data connection off. The drain should be between 2 and 5 mA for most of the time.
There are a few battery related threads, try comparing those results with yours, we did some extensive testing too in one of them.
To pinpoint your problem try one or a combination of these three tools: SystemPanel, Power Tutor, Current Widget (maybe one each night). Let them monitor your system overnight and see what's the result.
I have recently done testing for 4 nights, two with SetCpu underclocking profile at screen off, and two without it. There was no appreciable difference between the four runs.

i use an App to turn on airplane mode over night, i stared with an app called "sweet dream" [Link = http://www.androidzoom.com/android_applications/tools/sweet-dream_jtvk.html?nav=googleDownload ]
and now use timeriffic [link = http://www.androidzoom.com/android_applications/tools/timeriffic_tdl.html ]
it really does help the battery life.

Or just plug it in overnight? This seems to work fine for me!!

Have you tried conditioning the battery?

Calibrate your battery then reset your battery stats. It could help. If you flashed a rom while charging or during the first boot screen on first boot or on USB, battery calibration will need to be performed. It made a massive difference for me after multiple flashes.

I decided to install Advanced Task Killer, all is good now, must have been some app draining it.

Removing Bloatware aka "what can I do to get better battery life?"

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
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

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.

Is something wrong with my Xperia Play R800x?

Ok well let me just start off by saying. I LOVE this forum and the helpful and friendly people. Lemme give ya a run down on what I'm rockin' on this marvelous piece of technology.
Bootloader Unlocked - Check
Root - Check
R800x Timescape UK Firmware ROM - Check
V6 Supercharger - Check (Could use help making it start on boot.)
Better Battery Stats - Check (Could also use some more help since I'm a noob XD. More below!)
Battery Life - QUESTIONABLE
And here lies my problem here. Ever since I switched to the UK Firmware from Verizon's I've noticed the phones true potential and love the UK Firmware. However what is up with the terrible battery life? I've tried everything... It seems to DRAIN 1% every 5 minutes when I'm at school!!
BetterBatteryStats talks about wakelocks. I get this one sometimes called UID and have no idea what it is, and have looked for a solution but found never in ACTUAL terms I could understand. Also there's a blue bar and a red bar on the stats for those. Can someone please tell me the difference between them?
I've deleted Juice Defender as some people said it actually DRAINS your battery more. I've also heard this phone lasts sometimes 3-4 days on a FULL CHARGE?! I'd like that please! :O
Well when I'm at school I put my phones Brightness to 30%, Vibrate, and off WiFi.
I listen to Music and that seems to drain the battery ALOT more than I think it should.
Also, when playing Asphalt 6 HD, I was at 57% battery, I played for maybe under 10 minutes and had 44% LEFT!!! That's TERRIBLE!
Can someone please tell me how to make my battery last like others have it?
I also have 2X Battery installed but disabled and only showing my battery % on my taskbar up top.
Thanks again in advance for your answers and I hope I have provided enough info. THANKS!

If u don't use it during school then power it off. Also kill some tasks so your phone won't work hard and kill morw battery life.

I do use it during school. Sometimes as a Calculator, to text my family or if they have to call me in case of emergencies. I also game on it at lunch or listen to music when on a free period so...
And I do kill tasks all the time. It seems to just open themselves back up. Also I played Dead Space last night with 100% charge for maybe about an hour or 2 and the damn battery drained down to 55%!!!
I was on WiFi as well...

You honestly can't expect a game such as that to run on this phone and merely sip at the battery's juice. The percentage remaining when coming out of an intensive task, such as watching video or playing a game, isn't entirely accurate. Check the battery again after a few minutes of idle time, and it should be a little higher than it was before.
I use an app called Battery Defender. It's very easy to set up, and the main option is to kill the 3G data while the screen is off. You're still able to receive calls and texts and such, but the data is off, since you're not using it. That saves a lot of battery for me. You can also set it on a timed profile, where it shuts off all network connectivity during a set time.

Thanks I'll give that app a try.
Also I just feel I'm being mis-leaded by others then. Because I read on the android Forums people play games from 1-2 hours, stop, go to the store or mall for like 5 hours, come home, play again for another hour, and sleep and wake up with it at 7% charge or something.
Are you saying ti's normal for my battery to suck that much juice on Dead Space?

Dead Space is one of the most graphics intensive games you'll get to see in this phone. It's not Cut the Rope...

Well.. despite my other questions is anyone able to answer them..? ABout the battery stats app and such?
Also what would seem to be a normal rate of 1% battery loss? How many mins or hours do you think seems normal?

Did you wipe your battery stats before installing the rom? Let it drain to 0%, charge it without interruption? after that then you must let it drain fully and recharge too 100% without interruption again. This will "train" the battery. I have a battery calibration app if you'd like to use it

I would suggest you to do a fresh install. Wipe everything and start afresh. Don't restore anything and see what happens.

Yes I have done this. But ONCE. I haven't let it die again yet. Using Battery Defender is saving it's battery atm. Should I kill it again and let it do so?
Also for the Battery Calibration don't I have to do some weird thing with getting the phone to power on without the battery?

Make a backup of all your data, then do a fresh install. The battery calibration app is simple, charge your phone to 100% and click calibrate. Then let it die to 0% and fully charge without any disruption..it's pretty simple

Must I make a fresh install or can I do it without a fresh install?

The battery calibration has nothing to do with a full wipe and reinstall. The fresh install is simply to fix problems that you are having, that no one else has, or doesn't have in such great force.
If you're worried about losing your data, get an app called Titanium Backup. It will allow you to backup your apps and app data to your sd card, then restore them at any time you deem necessary. There is a free version, but I would definitely recommend buying the unlock key. It makes your restores faster, and enables some specific functions that are locked out of the free version. This is my third Android phone, and the app has proven its usefulness time and time again, across each of them. It's the best way to port installed apps from phone to phone, as well.

So does anyone have the link to that battery calibrator app?

I need a good battery saver app.

Anyone know of a good battery saver app that actually work? Right now I'm using juice defender ultimate and it is OK and I'm sure most of the problem is the rom I'm using (simonsimons34's cm9 for marvelc, great rom) I just charged my phone to 86% and 15 minutes later its at 61%. Any advice or tips are greatly appreciated, thank you.

Is deep sleep working on that ROM cause that's an awful lot of battery usage... Or were you doing something battery-expensive at the time?

I personally don't believe in battery saving apps. All they do is manage your phone's hardware (wifi,Bluetooth etc.) They are always running in the background so they use even more battery. Apps like BetterBatteryStats help you track your battery usage so you see what's using your battery the most and cut down it's usage

I agree, it's much better to do it yourself via a notification drawer power widget.
Make sure bluetooth and wifi isn't left on all day, turn off gps (gps is still on, albeit in a power saving mode, even if the icon isn't showing) when you aren't using it. Lower your screen brightness. Turn off sync and data if they're not needed, and go into aeroplane mode if you don't have any signal (because your phone will drain the battery desperately trying to find a network tower).

I don't think deep sleep is being used on this rom, and its still in beta so Bluetooth and wifi aren't working right now. I have easy task killer to stop running un needed apps and juice defender helps a little. I have had battery issues before but I seriously want to just throw it sometimes, I feel like I am always at the charger with my phone. But thank you guys for the help.

A task killer will only drain battery, trust me. Leaving these apps in RAM won't use up any more battery, but having them relaunch after you kill them will.

If deep sleep isn't working, you would benefit from setting a lower minimum CPU clock. You might suffer a slight performance loss when you unlock. Or otherwise, you can try setting different CPU settings for on and off state. I believe setCPU allows this but you'll need to check.
Helped me slightly with modpunks alpha 0 which didn't have deep sleep.
Without deep sleep, I'm afraid most of the other battery saving methods won't work much...

I dont think that setcpu will help completely, the mentioned drain of battery is a huge amount..and yes the best battery saver is yourself ..maybe your time time change the battery has come up?

I had the same issue a little while ago. when I checked in the battery section of the menu I found that "media server" was running ALOT. often it was using more battery than the screen. after reading a few posts and downloading watchdog lite to see when the process was running, I heard that it could be that the SD card needed formatting (and partitioning as I use INT2EXT). So I formatted my SD, made a new partition reflashed the ROM, gapps and script and BINGO. no more "media server", no more problem.
don't know if this helps but thought id mention it, it was driving me mad.

Help regarding battery life

Hi all I just got my galaxy note 2 yesterday but the battery life is bugging me.... I feel that it is not normal.. every 5 minutes or less the battery percentage drops by % 1 even if I am not opening any apps and I have GPS, mobile data and other unnecessary things turned off and just using Wi-Fi with power saving turned ON.. I even didn't used it that much yet, no videos or apps that consume a lot of CPU and I always make sure that I kill apps after using them, currently I am just surfing the web with chrome and it is still inconsistent sometimes it drops after 10 minutes and sometimes after 3 minutes, I also turn everything off except for power saving when I go to sleep but after waking up I noticed that it dropped by % 4 .. sorry for the long post guys but I am very worried and I just want to check if this is normal and if it's not I can get the battery or the whole device replaced since I have a 2 year warranty. I also attached some screenshots if you need to judge from them.

Have you updated your Note to 4.1.2?
I recently updated to 4.1.2 and my battery life has suffered.
Hopefully a new update will fix this.
Judging by what others have written, you should get between 6 to 7,5 hours with the screen on. I plugged mine in yesterday efter 1 day and 12 hours. This includes 8 hours om sleep and 6 hours at work -no time to use the phone at work. I did not make note of the screen on time.
As i write the phone has been on battery for 8,5 hours and the screen on for 1,5 hours. The battery is at 54%
Hope this helps.

It's that a task killer icon in the top left corner? If so, you might first want to try if your batterylife improves after uninstalling that!
Also find the app called better battery stats on play store. I recommend you buy it and install it. EDIT: there is a free version of it on xda too... Then charge your phone to full and use it normally. When the battery starts to get low again, open the battery stats app and look for "partial wakelocks since unplugged"
There you might find the cause of your problems. Post the screenshot of the partial wakelocks screen here if you need help interpreting it!

There is a free XDA-edition of BetterBatteryStats as well.
I got similar battery life as Dmwitz reported, no idea how some people get 3 or 4 days or 7,8 h of screen-on time out of their device.

I have the same problem as you

That icon in your notification bar... Is that a task killer? If so, then that's your likely problem.
When you use task killers, apps that restart themselves or their services will constantly be starting up again, leading to more battery drain. Let android handle your running apps and only manually kill apps that are frozen or highly problematic (uninstall those problematic apps if you can).

Thanks for your suggestions guys I uninstalled the task killer and will try the battery app now, I will let you know once I try it
