Crazy battery usage after OTA 1.72.405.3 How to find out what is going wrong?

Hi all,
After instaling OTA 1.72.405.3 the android system is eating away my battery like crazy.
After 5 hours my battery was down to 29% (71% was used) and the android system was responsible for 60% of this. In my CurrentWidget log I can see that (with the phone in standby) it uses ~130 mA to ~160 mA.
Does anybody know what is going on or can anybody help me by telling how to find out what is going on?
[edit: If you have the same problem, please post a reply so we can find out if this is a big problem! Thx]

This happened to me yesterday! Found out that the system process had pegged out the CPU @ 100%
I couldn't fix it, and in the end restored to factory settings. Has been OK today but I killed the battery in about 4 hours.

Radio and kernel updated?

yes, i have the same problem! i posted another thread about it (titled constant sync after OTA update) as i first noticed the issue when the sync icon was always being displayed.
today my battery hit 20% after 6 hours with android system taking up 50% of the battery usage. its ridiculous!
if anyone has a workaround or a quick fix please post it up - this is untenable!

I have exactly the same issue, no problem with battery life before the latest OTA, and now the phone is dead within 8 hours with no usage, simply in the pocket with the display off.
Not happy at all, the phone is virtually unusable at the moment as any action accelerates the drain.

Strange! My phone is now with more battery life, after the update. It is SIM free ...

I posted this in another thread -
There seems to be a bug in the update for anyone who had HTCSense.com sync'ing turned on. Either disable all sync'ing for that and / or sign out of that account. It was consuming 100% of my CPU cycles and keeping the processor at the 1ghz mark. Once I disabled the HTCSense.com sync and rebooted the phone, all is good. I went from 100% CPU usage to about 4% and less when idle.
Personally, I'm not sure about HTCSense.com anyways. Way to buggy. I have all my SMS's backed up with SMSBackup+ to my Gmail and my contact / calendar is on Google. I've Wave Secure to lock down the phone if needs be / to find it. I think it's more reliable as well as I used to get a lot of "can't connect to the phone" on HTCSense.com and Wave secure uses at Text Message based system to activate the necessary features along with locking down the phone if the sim is removed / replaced! NICE!
Anywho, anyone who is having battery problems / finding the CPU is topepd at 100% try the above and see!!

I followed up with this:
I must say, I'm quite impressed with the battery life since the update (after I got rid of the 100% CPU bug).
I plugged the phone out at 11am this morning. Quite heavy texts (50+ sent today and at least that received). 10+ calls (incoming and out going) at 3-10mins each. Some Angry Birds, Some Market Updates. Disconnected my Facebook Acc and reconnected to cure a bug in the calendar (facebook entries were there twice), so all that data had to reload. Twitter usage through out the day. WiFi on all day. GPRS Radio only.
Now at 12.15am (so over 13 hours later), I've still got 50% Battery left! I would NEVER have gotten that previously. Not with the heavy use I gave it today.
How are other people finding it!?

Thanks for that. I dont really use any of the sense features myself so i've now disabled sense syncing completely and will see how it goes (once its fully charged again!). will keep this thread updated with any news from my end in any case.

I did notice the sync logo was up quite a bit... interesting!
Mine did it randomly... couldn't clear it so just went for factory reset which appears to have fixed it!
May turn of HTCSense however if it is likely to be causing problems...

I got the same Battery problem after new OTA and Im going crazy! What can I do? My battery lasts only about 4 hours now!!!!!!
Should I factory reset and wipe everything???

As ive posted in a few other threads i went into stock application manager and force closed everything i could to do with google, htc , friendstream, maps, facebook etc. After that my cpu 100% problem stopped, has never returned and battery life has improved compared to before the update.

I have disabled now HTCSense.com sincronization. I will see how this works tomorrow for me. I will let you know guys

I had htcsense.com enabled but to be frank I never really used it much...
disabled its syncing (every 3 hours I had set), rebooted, still had "android system" at ~65% and htc sense running at about 15% (tell me, I use launcher pro 99% of the time, is there any way to actually kill the sense ui? I swear its in the background)...
This did nothing, I tried actually removing the account, and even before a reboot the proc. usage dropped down to about 15%, which was apparently being used by the monitor I use (osmonitor). rebooted, let the phone settle, it did a sync, all seems well... So in my case an actual removal of the account was needed.

Try turning USB debugging on/off. I have it off after the last OTA and I have no /INIT problems. Maybe they fixed it...

I had the same problem, with the cpu running constantly at 100%. For me the solution was to remove the HTC Sense account, and then adding it again. After this the cpu usage dropped to normal.

well its been nearly 4 hours unplugged and i'm down to around 80% with around 30m of calls made and a dozen texts. not fantastic, but much better then before.

Did you try USB debugging? previously that has been mentioned as the CPU eater and battery hogger... just a thought..

Confirmed. I had the same exact problem and removing HTC Sense account did the trick.
I tried adding it again, but the cpu drain started again..... so I'll use it for some time without SenseSync.

well it seems i spoke too soon. i've just woken up to find that the battery died overnight. so sometime in the last 9 hours i've lost 80% battery whilst it has been on standby.
prateekgujral, i currently have usb debugging turned ON due to the /init problem. are you suggesting that i turn it off?

It should be on So its good.. What about the sync tthing dicsussed above?

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.

S3 Massive battery and "Android System" usage with and without charging

I'm having a problem with my Samsung Galaxy S3 (rooted, but no custom ROM) through AT&T where it's losing battery power at a much higher rate than normal every once in a while.
Specifically, today, I was using the GPS feature and charging it in my car, and yet, even though it said it was charging, the battery continued to lose charge. Also, in the past, the phone has lost charge very quickly, and when I check the battery usage, "Android System" is very high on the list, up to 60% (with "Screen" being at 11%, which is usually the biggest culprit for me since I leave the screen on a lot). One time, I went to bed at around midnight and had forgotten to plug in my phone. When I woke up it was off. I turned it back on and looked at the battery stats using 3c's Battery Monitor Widget and saw that it lost charge quite slowly until about 5am, when suddenly the usage went up dramatically, and the phone went from about 60% to 0% in the course of an hour and a half of non-use.
Because this is not a problem I can reproduce on command, I'm not sure exactly what application/process is causing it. Does anyone have any suggestions or has anyone else experienced things like this happening before? (Besides me having to pay for the "betterbatterystats" app?)
Edit: Also, "Android System" sometimes is sometimes listed as "gsiff_daemon" in the battery stats, and within 3c's Battery Monitor Widget, Android System is separate from "gsiff_daemon", where gsiff_daemon's usage is almost 15 times the usage of Android System.

Checkout this thread to see if the gsiff_daemon is your problem. tl;dr when the system is hot and tearing through the battery, go to system settings -> Developer options -> and check Show CPU usage. If gsiff_daemon is the top or second highest on the list, then that is your problem. To solve it for the moment, use system tuner, or something else, to kill gsiff_daemon. There is no permanent cure at the moment, other than to delete gsiff_daemon. Both of those fixes require root, the non-root fix is to reboot.
If gsiff_daemon is not on the list, then something else is the problem, but Show CPU Usage should give you an idea of what system process is running hard.

Samsung Push problem
J M L,
Thanks for the information. I'll do that if the problem arises again. However I also did something else that looks like it may have been the solution for my particular problem, which was disabling the "Samsung Push" service in the Application Manager. So far, my battery life has gone back down to very reasonable levels.

Interesting, I installed "micro cpu monitor" shows thin line at top of screen showing both cores.
I haven't had this happen for some time now but after playing with google play and maps downloading offline maps etc I noticed my 2nd core pegged out.
Having seen this in the past & ignoring it I now realize that majorly drains the battery as well as it getting warm.
A simple reboot seems to be the only thing that fixes it. Clearing ram and closing recent screens dies nothing to clear the "cpu jam".
If left alone, it always shows the culprit as "android system"
As to what part of "android system" I don't know.
But until we figure this out for good, that little micro cpu monitor. App is sweet for peace of mind to know all is well or whether a reboot is needed. For what it's worth, I also noticed that after the event, that my auto rotate to landscape was mysteriously unchecked?
If it jams again, I'll have to see if it gets unchecked again, unknown if there is a relation.

do any of you guys have the "increase volume in pocket" setting on in phone-->settings?
also do any of you have motion settings enabled and/or autorotation on?
Seems it has to do with the gyro issue
also are you guys rooted or non-rooted?

Contact sync?
i noticed this today and while troubleshooting, noticed contact sync from google says "sync is currently experiencing problems..." maybe?

I read the thread about gsiff_daemon culprit. I had it listed as a possible battery drain culprit. The thread says the issue may happen after a hot reboot...which I did have. Killing gsiff_daemon was not immediately effective. I renamed the file so it wouldn't get used...like the thread recommended. I had to reboot to get normal battery drain back and have yet to see the issue again. But i wont know for some time...or maybe when/if i get a hot reboot...which is really rare. Do yourself a favor, and buy better battery stats. Its a must have tool...and it's not expensive.

I wonder if this problem has been solved with latest lj7 jellybean from sprint

so with some trial and error i found some resolutions ..
first, i used Watchdog and it told me that the media services is killing battery too.
so doing a full wipe does not always fix this.. but what does, is reboot and wait about 1 hour charging and it will calm down. this was just something i noticed. so what i did is wipe out my SD cards, both of them, cleared them out 100% formatted the External SD, and used recovery to format the internal. From there it seem to work, i put my stuff back, and it seems ok.
problem is, when you install a lot of rom's and have bad reboots some files get messed up and you have to do it all over again..
problem was with AOPK, CM and TW roms.

My experience with froyo/gb/ics is that things have been getting progressively better over the years. But with each so called UPGRADE of an OS or even APPS, we often have to deal with bugs or incompatibilities. I am eager to upgrade to a stock based JB soon, but wisdom says, for 20 things improved, there will be 5 things broken....or hurting in some way. Early adopters suffer the most as usually these issues get ironed out...most of them.
BUT...these stuck drains...wake locks etc., it seems they will happen when they do no matter how many issues get fixed. Over the years, I've had random standby drains caused by Maps/Nav. Maybe it's ok for months, then after a particular update, it's back...and unpredictable. The YES...a reboot, just like with a PC, is a quick short term workaround.
Finally, with the App CURRENT WIDGET, there is a provision to watch for high drain in standby. It watches MilliAmp (ma) readings over time..to determine if you have a rogue drain. That's different than monitoring the CPU. (Some drains do not cause much CPU activity) BUT UNFORTUNATELY, that app won't work with our S3's because of a lack of hardware support. Works great with HTC and many others. It's a bummer because I used to use it and have my HD2 reboot if a 15min consecutive high drain was recorded in standby....thereby saving the battery and usually killing the bug.

Crapppp
Jellybean didn’t solve it. Gsiff_daemon just popped up for me. Just renamed it AGAIN.
Hopefully it won't pop up again

[Q] Why Battery Draining Fast?

I have owned this phone for about 3 days, but I have some battery issues.
I attached 3 pictures, and on the first picture, you can see there appears to be no wakelocks, but on the 2nd picture, the Android OS used the vast majority of my battery life, and the 3rd picture, Android System has a lot of "Wake Up Device" (i don't know what the number means is it minutes?)..
I have uninstalled/disabled most of the apps I don't need, and have the brightness set to low, and on airplane mode with all sync off, and zenmotion turned off, and this still happens. I lost about 11% battery overnight with this problem. It seems like when I am using the device, the battery drops a percent every minute even when I am just scrolling through the Settings.
I only used about 1 hour screentime on this phone and the rest on idle.
I already installed both system updates.
Does anyone know why this happens? I know there is a memory leak problem, but I saw on another thread other people don't have that bad of a drain anymore...

For battery draining assistance see ZenUI app called ASUS Support: Apps/ASUS Support/Assistance/Battery/Battery drains fast/follow detailed troubleshooting steps. If battery still draining, recommend updating to latest firmware version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Mine seemed fine for a week and then I got this today. Pretty much done with it. Can't even get it to factory reset.

hello guys i am getting screen on time of mere 2 hours without any significant use on my ZF 2.... i have stock rom. no root nothing.... can anybody help me

Battery drain issue still not fixed with updates???

Disable PC Link and Party Link default apps, worked for me. They're default apps using cpu all the time like they're SO Android... Disable all default apps that you don't use too

I've got here two brand new models, which differ only for touch and battery version (Z2C3 01040005 1525 and ... 1526)
The 1526 doesn't show any drain. The 1525 does, as of its very first boot. I tried keeping same settings of course.
I'd like to point out that when connected and charging it shows big steps like going from 63 to 72% and it also reaches 100% in less than 60 mins.
When disconnected the discharge path exhibits about 1:15min of operation.
May I suspect the battery is defective?
PS: after a factory reset from recovery seems have fixed the problem for now at least...

Asus Zen phone 2 laser battery drain ?
I made an account with this website and took the time to write this, so I can let users who own this phone know one of the
biggest battery drain features I've found......DISABLE HOMESCREEN APP MOVEMENT SENSOR, in app icon settings.
When you tilt your phone app icon adjust to the tilt, yes looks cool until you realize how much battery you could save by leaving then static and not constantly running a fDucking tilt sensor.

Battery Drain Advice

Hi All
Disclaimer: I'm new to the forum so apologies if this is in the wrong discussion area etc!
I got my Galaxy S9 on Friday 9th, prior to that I had an LG G5 which is now gone. In the last few months of using my LG G5 the battery life was questionable - the phone would get hot (sometimes without even using it a lot) and the battery would drain by 30% an hour. I noticed, but didn't test fully, that Google Play Music seemed to really cane the battery and phone - i.e. was getting hot and draining quickly. As an example, I'd leave home at 7am taking it off charge at the last minute (100%) and get to my office at 9am and it'll be at 50% and very warm. Prior to that (can't exactly pinpoint when the drain started to really kick in) it would only drop to 85% - much more acceptable.
The G5 has a replaceable battery - 2800 if I recall . So I threw down £50 on an official LG site for a new slab of Lithium - slight improvement, but still terrible and warm. 55% instead of 50%.
"Right - time for a new phone" as I assumed that 2 years of app updates meant the CPU was lagging. Bagged a Galaxy S9 - today was my first commute into the office. Started on 100%, arrived at 55% with a 3000 battery! And it got super warm like the G5.
Most of that time I used Google Play Music, which according to AccuBattery the discharge speed was "33% per hour". Second was Google Chrome at 30% per hour (though I didn't use it much at all on the journey).
My question is - what logs can I check, or apps I can use, or something to find out what's going on? I need to test a few things of course to pinpoint the issue. If it helps - I restored from my G5 when I setup my S9.

seems like you might have have some options enabled in Google Play Music / chrome - that is keeping the phone awake
generally when you switch phones they apps and their settings get transferred automatically now - worth maybe uninstalling them for a day and see if you're still experiencing this issue
other than that it could be that your commute involves travelling thru areas of no signal where the phone keeps trying to find a signal - that can drain battery a lot

Thanks - I'll try that next time. Might also try a factory reset but not restore from the LG G5 backup to see what happens then.

how bright is your display? do you leave it on all your commute?
Got your wifi enabled which hunts for a signal even though you aren't using wifi? try turning it off. Same with location setting.

And how strong a signal do you have on your commute. Streaming lots of data on a really weak signal will kill battery, too.

Go into settings and see whats draining your battery.

Battery Drain Issue of S9 - Resolved
:laugh:Hi All,
I could resolve the Battery drain issue but not touching any other setting of the new phone by just disabling the backend data usage of all application expect few like Edge screen, Gmail, Flipboard etc... Now the android system power usage is back to 4-5%. Previously it was 21%-25%. So issue resolved. Need to find out the way to inform this to Samsung so they can identify which app is consuming full battery power.

Hi, i'm facing ridiculous drains too and factory resetting hasn't seemed to help. I'm trying your resolution, but I don't entirely understand you. Could you kindly guide step by step? also, if you mean going to optimise battery usage, when i go there and select the 'apps not optimized' all the apps there are greyed out therefore not allowing me to select them.
