Fast Battery Drain over night

Hi guys,
I have a problem with my Jade. I've charged it last evening and I've barely used it. When I've went to bed it was 96% charged (ARIELbattery) and 10 minutes used.
This morning, when I've woke up, The battery was 33% and and the phone was 34 minutes usage time.
Something is wrong. Since there were no bluetooth, no wifi, no anything activated. And for sure, nobody played with the phone during the night.
This is not the first time when I see this behavior, but is the first time when the decrease is so big.
I suspect an app, but I do not know which of them. How can I see it?
Do you have other suggestions?
thanks!

There are some possible reasons:
Some SD-Cards seem to drain battery, so you can take it out for a test.
Some additional software is told to drain battery. Did you install something?
It is also helpful to switch to "flight-mode" over night. This normally reduces battery drain to nearly zero, if no additional consumers exist.

Hi,
Yes I've installed some software, like gAlarm, S2U2, icontact,ThumbCal, Skype, etc but last night none of them was started.
What can I do with the SD Card?! I need the SD-Card. Which card does not drain battery and which does?
I cannot turn off the phone over night.

I've read those before posting, but there was no answer to my problem. I have 67% drop of battery in 8 hours without touching the phone.

This is most likely that your device goes to screenoff or unattended power state instead of sleep. Your power settings might be corrupted. To change that go to your power settings advanced tab and change everything there (checkboxes and sliders), press ok and then change them back as they were, press ok. I'd suggest to keep the device turning off in one minute while on battery and none of the checkboxes for cord powered mode. There is a really freaky thing that even if you get your device to sleep with power button it will go back to screenoff mode after time specified by the turn off device slider while on battery IF you don't have that turn-off-while-on-battery checkbox checked there.

Thanks for the answer. But I do not really understand what you are saying here.
My power settings are: 30sec for Screen Light and 1 min for Device (on battery).
None of the check boxes is set for the case when the device is powered.

It could also be due to the battery defect. After some time the battery could lose its storage ability (because of the defect), despite the mAH stated.
As a comparison, my battery is nearly one year old. On full charge, overnight drawdown (on sleep mode) is about 2%-3% .

I have no own experiences with this programs but Skype for example needs permanent connection to internet when activated (be care of the background job!). This uses data connection and this drains battery. I can not quantify this in %. In addition Skype does not allow the system to switch to deep sleep because it needs permanent connection!

None of the app was started. I just have Skype installed, but it was not used.

Uninstall S2U2 !!!!!

I found some German threads that discuss a problem with this software and battery life. Some loose 10% over night others 50%. I think you should try to uninstall (and afterwards soft-reset!) for a night and see what happens.
Please keep us informed.

First of all, I've disabled the 3G. Now it only gsm with gprs. Since I've done this it seems the battery drop is ... super ok. If yesterday morning I've had 33%, this morning I've had 20%, so 13% drop in 24h, and the phone was used normally as before.
last night the S2U2 was not started.
I will wait until the battery level reaches 10% an I will do a full charge.
I will keep you informed. Thanks to all for advices!

Some clues here too ...

Hi,
So now, 2 weeks later... after setting my Jade to GSM only (no 3G) I get 7-8 days of normal usage. As I said, before I always had to charge it the third day.
Normally, i get -28mAh drain in standby. When the screen is on around -130mAh (for wake up) and then -70mAh. In a gsm call i get around -250mAh.
I did not switch the phone back to 3G yet, but I will and I will see again the battery drain.
PS: the values were provided by Mobadi.

i believe i have S2U2 installed... and my phones fine!
i have the overloaded rom... and battery life seems great only needs charging every 3 or so days and i do use it quite alot!

so...
after some time of testing and re-testing I still have, from time to time, the behavior that during night I see a massive drop in battery level and an increase of the usage time.
I do not know what is going on, but I suspect that some app is waking up the device to do some work (without turning on the screen), and the Jade cannot go to sleep anymore for a while.
I've notice the same behavior on a HTC Diamond 2.
Since none of the app I have installed on my Jade are installed on my friends Diamond2, I have no idea what app could do that.
If anybody has any idea, feel free .... I am idea-less!

I've made myself a little application to log the current values of the power data. So, I've saw that my phone wakes up each hour by himself, without turning on the screen, does some work (cca -70mA) and after 30sec goes back to sleep.
Any ideea about this?

[Q] A500 shutting off overnight while charging!!

I'm having problems with It shutting off overnight while charging. Anybody else having this problem?

I just discovered this "feature" this morning as well. -_-

Did u find how to fix this?

I love the feature where the A500's battery doesn't last overnight with the screen off. I didn't think I needed to charge it overnight since the battery was at 95% anyways, so I just set it on the table next to my bed and went to sleep. Woke up this morning and it wouldn't power on. Pretty cool. Wonder what is draining the battery? My DroidX can sit on the same table for almost a week w/o being charged.

I haven't seen it, then again I play music from getting into bed till I wake up so ill try leaving it to sleep and see what happens.

Me too
Same issue here.

i have not tried the trick that I just found that seems to extend the batery life....I put the tablet in "airplane mode" , enable the WiFi and the battery looks like it is draining alot slower. There is power being used for "cell standby" even though is a wifi only tablet

Same problem here with shutdown on charge. Right now it seems fairly consistent-

I'm experiencing them same thing when leaving asleep for extended periods. It first happened while I was charging... now it happened again when I left for dinner and came back. I don't see any setting options for that

Same here. Thought it was a "feature" to keep from using as much battery.

So shutting off notifications seems to stop the problem for me.. except that I don't get notifications At least it boots pretty fast

Lets run some tests, shall we?

I don't think they're shutting off, I think they're crashing/freezing during sleep and not rebooting.
This is speculation by me, and could be different for different people.
Finding the problem:
The test.
Night/Bedtime
This is an overnight/while you sleep test and requires about 2hrs. of your time beforehand. Record your figures if you can and post them for debunking. A couple hours before bed and while you use the tablet during the evening, charge it. After 100% and once it's off the charger please don't use it for anything. We want to simulate the sleep process for about 90m before bed. So if you use the tablet even for a quick web surf, plug it in and getting back to 100%. We're going to allow ~3% for errors anyway but we want to be as close to accurate as possible.
90m before you're ready for bed remove the charger. Don't use the tablet simply set the brightness to auto and take note of your battery level and the time. 60m in take a look at that battery charge again and record the time and charge level. 90m in is the last check and after this whether you go to bed or not please don't wake the tablet. Don't worry if it seems to wake and go back on it's own. That's inconsequential for this test. Just put it somewhere that no one will bother it and resist using it until you wake up. Please
Morning/Wake time
Wake it up.
1. Comes on? Record the charge level and time for posterity so we get an idea of idle drain here on the thread. Everyone gets different values. You'll have to run this test at another time as your shutdown/freeze hasn't been reproduced this time.
2. Doesn't come on? Try a power on press. Comes on? Same as 1. Record the charge level and time and post it here.
3. Doesn't come on? Try a power on press. Doesn't come on? Plug it in and power it on. Now do the same as 2. Record the charge level and time and post it here.
I hypothesize a few different scenarios the summary of which is that I don't think they're shutting down, but this is mostly based on the assumption that the batteries are being charged while the unit is frozen. If they do not charge then my entire test would have to be re-designed. I surmise they freeze and don't restart so they either run out of juice or they're actually frozen when you try to power them on and the long press is rebooting the unit, not powering it on. If I am right then we should see that the batteries are drained as if they have been on all night. This is going to be very imprecise, but my idea is that we'll take the charge % of your bedtime check which is a 60m mark check and just times that by the amt. of hours you were sleeping.
So if you were at 95% when you touched the tablet for the last time, this would mean a drain of ~5% give or take ~1% due to your use while checking, per hour. You take that and multiply it by how many hours you've slept and you'd get X x 5 = 40% which leaves the tablet with ~60% battery when you wake up, again give or take 3% for errors, syncing during the night etc.
If you're seeing a somewhat accurate numerical representation of this formula then it means the tab drained all night.
If you're seeing something way off like the tablet still having way more than it should then it means at some point in the night it really did shut down on its own.
People who are actually saying it shut off probably just reboot the tablet without realizing it as it was on the charger when it froze. Since a power off/reboot press of the power button is roughly the same length as a power on press, it's difficult to differentiate sometimes.
Solving the problem:
I have had this happen twice and it was while I left GPS on.
I haven't had an android cell phone yet that hasn't frozen or reboot itself when I left GPS on for extended periods (aka overnight) so the first time this happened I instantly knew to check and I purposely left it on the second time to reproduce and the second time, the tablet ended up rebooting not freezing. If you're not technical the easiest way to know if your tablet reboot during the night is to leave a web page or IM window on the screen or leave music playing.
You may want to skip the above "finding the problem" tests and attempt this "solving the problem" test. As I mentioned, this is all speculation so I'm just trying to get to the bottom of it and I'm sure we can as a grp.
Once you rule out hardware though, then it's a problem. So if it is indeed NOT the GPS then we're at the mercy of Acer and Google because otherwise there'd be just too many factors to track down.

I'm getting this and i'm loosing a ton of battery somewhere in the process too. I think the above poster is right.
I plug in tabby. go to bed. wake up to pee. see tabby is 100% battery. unplug and go back to bed. wake up to go to work and tabby is powered off completely and battery is anywhere between 85%-90% in a matter of 2-3 hours after being unplugged.

Its likely a rogue app I would get a program like advanced task killer watch it and see what apps are loading in background after you kill all apps.look for apps you installed.not so much the ones Acer put on your tab.
With Ti backup freeze the first one you think should not run give it a day.if that's not the issue keep going down the list.
Had a similar issue it was a app I got from amazon.that was So CALLED FREE.they are not so I uninstalled everything from amazon. No more battery drain.
SOME APPS do not fallow the drained android or social rules
Watching the apps to be sure nothing is running CPU cycles allow the time I loose about 2 to 3 % batter life over night with wifi set to stay awake.
This is ideally from 11 pm until around 10 am the fallowing day.
Yes I sleep in alot giggles

re-flashed with Taboonay v.2.0/Richardtrips v.3.3 Kernel and it fixed everything.

Question about sleep in Iconia Tab

Hello all,
Trying to find some info about some behaviour my Iconia has.
I love my device. Way more capable than my wife's Ipad and all that. There's only one thing that irks me: battery drain while the device is idle.
I also have a B&N Nook 1st gen (for books) and an EVO 4G. I leave and use the Iconia mostly at home, close to the WiFi. I'll take it out for long trips and such, but it stays close. I have it set up so that the WiFi antenna turns off when the screen does. Low brightness on the screen, will only charge the battery when it's low enough to charge, etc. It stills drains close to 6-8% if I leave it alone a couple of hours.
Earlier today I rooted the device and use Bloatware Freeze to freeze some stuff. Eventually I'll get rid of some of the gunk the tablet has installed. I want to figure out how to shorten that gap. It doesn't make a whole lot of sense to me that the tablet left alone consumes 8% of battery charge! I mean, if nothing can be done then so be it, I'll learn to live with it.
For my money I would bet that there is something hidden in the Iconia's OS build that thinks it is a 3G/4G device. Now, I'm wondering what would happen if I were to take the next (logical) step and put another ROM in it. Would this make a difference? If I can make the battery drain stop at 5% or less, that would make this perfect.
Thx!

I leave my device with airplane mode checked, and then re-check wifi (as airplane mode will initially turn off your wifi). I get no strange programs showing up in battery usage now.

Will certainly try...
I'll try this next time I head out. Will leave her in Airplane Mode and will check the battery level when I come back.
I did disable the GPS and all location settings. I do not need it to know where I am, since I have the EVO for that.

Well I'm glad I came across this. I didn't even think about leaving the GPS on and consuming battery. Also, where did you adjust for your wifi to turn off when the screen goes off?
EDIT: Nevermind, I found it.

I am developing an app that uses bluetooth and I noticed that if I leave bt on my tab will go dead in 2 days, if I turn it off it can stay idle for several days before needing a charge. I leave the wifi on all the time.

Wow I don't even have 8% drain with Wifi on all the time. There maybe something else in the mix. Most of my drain is the screen as I set it to auto and in my home it ramps up brightness most of the time. Is it possible you have a rogue app? Have you tested the tablet 'fresh', ie: after a factory reset with 1 google profile set up?

This is interesting, on 3.01 & 3.1 I've had zero drain with screen off w/up to 16 hrs. Settings : Wi-Fi disconnect policy never when plugged in, location & security use wireless networks on & gps on. Airplane mode , always off. I can't understand why you folks are having these problems. Hope we find out. Oh & by the way that's not charging.
Forgot to mention I use Juice Defender.

Update
Well, after much tweaking I think I'm somewhere where I feel comfortable. As a disclaimer I don't take the Iconia with me on my daily commute. Again I take my EVO and my Nook with me. The tablet spends the entire time I'm out in the office at home, unused.
I disabled all screen animations and I'm using the tablet on the lowest brightness setting.
I disabled the GPS and all location-related settings.
I rooted the tablet and am using Bloat Freeze to freeze/disable some of the Acer 'junk'.
I put the table in Airplane mode before heading out.
Last night when I went to bed I didn't use it (I was reading a very good book and I did not use the tablet to watch any of my shows). So I put it in airplane mode after I played with the new Google Music app (Impressive!). I went to bed around 11:00 and woke up at 5:00. In this span of time, battery went down by 1%.
Used it this morning to tweet, check a couple of websites, email. Was @ 71% at 7:00AM. Came back close to 7:00PM. Battery was at 67%. Right now (8:50 EDT) it's at 1d 19h 55m on battery @ 59% charge. Heavy usage of TweetCaster, TuneIn Radio, Browser, Market, &c.
Mind you, it was not used for close to 8-9 hours or more. If I were to take it with me the consumption would be more, but then I would probably use Airplane mode when it was not in use. Besides, I can't use it at work b/c the wireless is not compatible.
I'll keep doing some research, but I'm comfortable. I accept the fact that it will drain regardless, since the OS is up. The previous consumption was too much, and I think I can live within the 2% - 4% consumption rate. If it can go down to 1%, though, that would be even better.
Any other ideas welcome.

beautiful Widgets comes with a widget to disable/enable wifi like we're all used to on our phones.
I loaded prime 9.3 today because I wanted to try a 3.2 rom (for GPS and sd-card reasons). On that rom I noticed the 3g settings were visible until I added the line "ro.carrier=wifi-only" to build prop. I was able to see cell standby show up in batt usage.
Not sure if you guys knew it or not but under battery usage you can click on the graph to see a graphical depiction of what hardware used the battery when. If GPS was active when it shouldn't have been you'll see it there.

Interesting...
Are you suggesting that the 3g apk is active on the 3.1 image? I posted this question to a developer in Market that has an app that kills this on the Iconia. Maybe that's the other 2% - 4% I can kill.

Prime is a 3.2 rom. You could try adding that line and rebooting though.

To the stock 3.1 image? Interesting. Any instructions?

You'll need an app like root explorer that will let you mount the /system partition as read/writeable. In the /system directory there will be a build.prop file that you can open with a text editor (root explorer has this feature built in). You'll see many "ro.xxx" lines. At the end of the first group you'll just need to add the line "ro.carrier=wifi-only" without the quotes. Save and exit the file. Reboot tablet. On reboot, it will read the values in build.prop.
On the prime 3.2 rom, the settings for mobile networks are visible without that line added to build prop. I was actually seeing cell standby in the battery usage list. I never saw that on the stock rom. I use a toggle button for the wifi to quickly turn it on/off from the home screen and that keeps wifi from using any battery while sleeping..
I really doubt that GPS is the culprit in your case. Did you click on the battery usage graph to see what hardware was using the battery during the period of sleep?

Also remember
The % charge that the system reports is not always a very accurate indication of how much charge your system actually has - what matters is up time and how long you can go between charges.
Airplane mode is your friend - no real need to disable animation (has nothing to do with idle charge) - the only thing I do is enable airplane mode when away from charger and not using my tab - some of the drain you are reporting could be due to your system scanning for open hotspots.
Also remember all it takes is one poorly coded app to totally screw your battery over - as you are rooted, quite easy to check for apps that relaunch themselves even after closed, apps that want to phone home every 60 seconds - etc.
Would highly recommend you take a close look at any non-stock apps that you have installed.

Battery problems?

My new note's battery seem weird after I let it run to 1% and then charge up to 100%.
After that, it seems to lose battery very much faster.
Left overnight, it went from 79% to 49%!! a 30% drop!!
I checked Battery status report battery health is good and average 33-35 degrees temperature.
Bulk of battery usage is reported for Display (62%, "time on" of 1hr 30m) ...
Is this normal??
What can I do?
Thanks.

Maybe the battery needs some recalibration, run it down to 1% then charge the phone while its still off.

Here's the battery level profile...
Not sure what is keeping the phone awake even while screen-off??
Any help or advice to diagnose and resolve the battery issues appreciated.

Try a factory reset and then calibrate the battery.

Just woke up after the first night with the Note. I had 45% battery left when i went to bed, and now 9 hours later it's at 43%.

You diagnosed the problem correctly by identifying the device being awake while the screen is off. I suggest two tools to narrow it down:
1. Cpu Spy, Market, free, displays how much time the CPU spent in the different power states. During the night it should almost completely be in deep sleep.
2. BetterBatteryStats, Market, ~2.50$, allows to identify apps with wakelocks, apps which prevent the system to enter the deep sleep power state while the screen is off and the device basically is idleing. On CM Spareparts xan do that for free, for Samsung devices I first have to find a free alternative app that works...
No wipe needed (yet), no delete this or do that. First find the villain, then shoot em, not the other way round.

Installed BetterBatteryStats,
but there is lots of information, and I have little clue what these constitute or how to identify what apps cause the issues??

You could post screenshots of all the screens of betterbatterystats and we will try to help you.
Charge the phone to 100% and disconnect it right before you go to sleep, enter cpuspy and reset its counters. Then enter task manager and kill all the programs and clean the memory. Now go to sleep and when you wake up post screenshots of the built in battery stats, betterbatterystats and cpuspy.

Hi
I have a similar problem, my battery keeps draining entirely too much for what I think it should. Mine gets drained about 40% in about 10 hours of very light use.
BetterBatteryStats shows it is WiFi that has a humongous amount of wakelocks, but the thing here is I have WiFi disabled.
Image (BetterBatteryStats): http://antti.vahtera.org/images/SC20111221-020623.png
CPU Spy shows nothing that looks that weird to me, although I rather wonder why so little deep sleep and so much 200MHz, but that might be if deep sleep has a longer "counter" than it did on SGS/SGS2. If I use the phone to check time, or twitter from a widget couple of times per hour, does SGN enter deep sleep during those "breaks"?
Image (CPU Spy): http://antti.vahtera.org/images/SC20111221-020441.png
But, the one that caught my eye, was the stock Battery Info window. During the (almost) entire 10h time the phone was awake?! Why in the whole wide world? Does SGN really have some bug with WiFi keeping it awake even though it is disabled?
Image (Battery Info -window): http://antti.vahtera.org/images/SC20111221-020744.png
I really wanna get behind this. I love this phone, but this battery drainage begins to be a problem for me. I got about 2-5% drain per night with SGS2 and 10-15% per day on similar usage.

yeah, there's something seriously wrong with your phone. Are you rooted ? would you consider a full wipe and maybe a different ROM ?

Not rooted, not modified in any serious way either. (Using GO Launcher EX, not TouchWiz launcher, that's really the extend of modification on this phone.)
Android version is 2.3.6, Baseband N7000XXKK5, kernel 2.6.35.7-N7000XBKK4
This is what was shipped with the phone. It's unbranded and unlocked.
I haven't really done anything to it but installed apps from Android Market (and a couple with Samsung Apps).
EDIT: This is my day-to-day phone with all settings as I like them and all things set, so I would like if I wouldn't have to do a full wipe. But if nothing else helps, I guess I'll have to, in the end.

I hope someone will be able to help you cause I've never seen anything like that.

This might help...
I had the same problem. The first night my Note was dropping from 100% down to about 50% when I was asleep and the screen was off.
In the battery stats I could see that it was the Android core that used all this power.
So I tried a couple things to see if it helped:
1) I went to WiFi-settings and set it to turn off WiFi when screen off. This is a setting that is not on by default, you have to set it yourself.
2) I turned off AutoSync (Google account and so on)
Those to settings removed the overnight powerdrain problem. The next night it only went from 100% to about 98% when I slept
And since I am a serious betterysaver I also turned off autolight on screen, and set it to lowest light possible (still nice picture). I turned on the "Autoadjust screenpower), turned off all animations, turned off all kind of vibrations on the phone.
I left the"System powersetting" alone. It didnt save much power and it made the phone slower.
All in all, now my battery is great, I still have lot of juice left after a full day of using my Galaxy Note

I seem to have fixed my problem, without having to do a full wipe. I don't know which part it was that finally did it, but I'm glad it now behaves like I think it should. (about 2% battery drain in ~5h in pocket, one 1min phonecall and two or three times checking time from lockscreen.)
Anyway, I apparently ALSO had the infamous problem with Mediaserver eating humongous amounts of battery, so I'm not sure if that had anything to do with the WiFi keeping it awake or was just a separate problem.
Long story short, here's what I did:
a) installed JuiceDefender, had it manage Wifi
b) turned Wifi on, restart
c) turned Wifi off, restart
[d) installed nomedia manager and excluded most directories from mediascanner]
e) turned phone off, recharged to 100%.
Seems to be working now. No WiFi wakelocks, no mediaserver eating CPU, deep sleep ~70% of the time.

Battery drain while sleeping

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.

Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )

I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))

I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.

Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/
