[Q] Need help, battery going down fast since firmware update

So i run 2.3.3 unrooted and updated to the latest firmware.
Problem is my battery goes down so fast now. 08:00 to 18:00 and it is dead. I havnt even used it much.
Normally i can just about squeeze 2 days out of it, now it is only lasting 10 hours.
If i click tools, settings, battery use, the processes display very fast, then disapear so i can not even see what is draining it.
Can anyone recomend a battery app so i can see what is using all the juice?

Use battery life calibration to reset the battery cache first.. Also see what is eating your battery after the reset

Thanks for the suggestion, but.....
1) I am not rooted as stated in my original post (so cant use battery calibration)
2) I cant see what is eating the battery as the processes disapear when i try to look, as i also stated.....
lol
Any other ideas?

Could be that your RAM is getting chewed. Buy juice defender ultimate and memory booster lite? See what's running around in the system and do something about it, root or ignore
Reason your phones dieing fast? Maybe you DLed alot of apps and they run in background, using battery.

Sorry I don't have any suggestions to your problem but there's definitely a bug or two in the new fw?
This is how my battery usage looks like. First fpse took up three rows of space but then it all of a sudden took five rows?

Havnt downloaded anything since i updated. Apart from the firmware update, everything is exaclty the same.
I think i have found the answer anyway.
There is a new feature in the firmware update that tells you when you lose signal. I presume that it then searches for a new signal and thus wasting the battery in a way that it didnt do before.
I work in a concrete building where the signal is constantly on and off and i believe that the phone is constantly scanning for a signal, probably a new feature of the firmware update.
I am going to swith the phone to GMS only tomorrow and see if it makes a difference. (gsm is a stronger signal where i live).
Im quite sure that is the reason.

Yes, this is the exact problem i have too.
Definately a bug.

Also take into consideration that if you have xLoud switched on this is also a sure way that your battery life will drain if you have a lot of audio playing.

There's nothing at all new about this. Every single cell phone released does this.

Yes i know.
But the way the Xperia Play does this has changed since the Firmware update.
I know it has changed because now there is a message that is displayed as a notification. If the notification process is constantly cycling, which it now does since the update, and not before, this may be eating up more battery power than necessary.
Since i have not changed anything on my phone, the quick death of the battery is most probable something to do with the firmware update. I believe this change to be the most likely candidate since it is the only thing that is constantly cycling on and off.
Either that or the SE data widget is eating up the battery since that is the only thing i have added to the homescreen.
Both are possible i guess.

Your device searching for a signal is exactly what is killing it. I know on any of my verizon phones I have owned when I am in an area that has little or no signal my battery will die in just a few hours. Not sure what the device is like over seas, but any time I have a crappy signal my battery will deplete very very fast, but it usually shows up in battery manage as cell standby.

Ok,how do permanetently SHUT DOWN the Phones Signal Searching? It also drains my battery too >_>

Settings, Wireless and Networks, Mobile Networks, Network Mode ----> GSM only.
This will not eliminate the problem, but it will prevent the phone searching for the superior WCDMA signal. The downside is that you can only get G and E data connections. But......this doesn't matter because if you are in a weak signal area you have no hope of getting an H connection anyway.
GSM is generally a stronger signal in my area. Probably yours too (and thus reduces signal search cycling even further because you are going to have a signal for more of the time).
I will test this tomorrow and let you know how it goes. I am sure the Firmware update has caused the phone to cycle more frequently when seaching for a signal and this is why the battery now drains faster.
Thanks to the poster above who confirmed this drains the battery too.

What you could do is do what I do... I use Tasker and have a profile that turns on airplane mode if it sees that the connection has dropped to 0, such as when I'm in the underground parts of my work building. Then every 9 minutes, it will turn off airplane mode, check for signal again for a minute or two and if there's still no signal, back to airplane mode and repeat.
There are also a few apps you can use such as NoBars that can help you do the same thing easily.

The same problem after Update to newest Version. The Network Standby is the Energy-eater in my Batterystatussettings.

Is there a solution to fix this?
Im currently losing 10% battery every hour and not even using the phone!

Anyone has any suggestions?
I currently consider my phone broke since the battery goes so dam fast.
I have not used my phone at all and am now down to 35% after 4.5 hours usage.
This, at the moment, is completely unnaceptable. Will make an offical post on the Sony forums when i get home.
Firmware update has definately broke the battery usage when you are constnatly traversing in areas with little to no signal.

Use Nobar, airplane mode....

I guess it will happen to all phones with the new firmwarw and constantly in areas with little or no signal.
I am guessing the signal search frequency has been altered for more search attempts per minute or whatever.
Going to try nobars. Thanks for the suggestions all.

"Android OS" consuming battery [POTENTIAL SOLUTION]

EDIT
I was able to solve my battery issue by formatting my SD card. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).
Important to note, I am not entirely convinced that the Android OS and battery drain are related since I still have Android OS near if not at the top of my battery consumption screen, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck!
ORIGINAL POST
I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.
I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else?
Screenshots show the device at 38% after 6.5 hours off the charger.

That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?
And not to be too obvious, but is your 4g antenna turned on?

No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.
I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices and was hoping someone might have a similar experience.

I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.

Same here too

I had this exact issue and no longer do. Here is what I did and posted in another thread:
OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so

does the google voice widget pull data in the background or is it a push thing?

I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.
Watchdog Lite indicates that this is primarily due to two processes:
events/0
suspend

Are you having battery drain problems? It appears your phone is awake more than it is in deep sleep. Have you tried the good ol' battery details screen in settings to see what your top usage is?

Oh... and this is only 1 hour of screen on time...
I guess my cell signal kinda BLOWS??? could this be the culprit?

Your signal search seems to suck, may be one issue. Another thing to try is go to system/bin and delete at add .bak to qosmgr and gsiff_daemon. They tend to try and run scripts for your CPU that don't apply. Next, do a Google search for kill media server apk. When you run it, it kills the media server that tends to eat a lot of battery. Disable sync on Google magazine/book/movies also. Last, buy gsm battery monitor from the play store and also battery battery stats. They will identify what's eating or power supply. Almost always on power up you can see the download/media app runs like crazy and if you don't force stop will just continue to drain and run.
You may also want to check into different governor settings to see if it will help. I also found it helpful to turn off Facebook sync unless i use the app....do the same for others u don't use like Google talk, maps, etc.

You seem to have a wakelock issue. Did you turn off google now and disable report location in Maps?
Also, if your signal is the problem, you can test that by either 1) disabling the cellular radio (airplane mode + wifi on), or 2) by forcing roaming on another network with a better signal (roam control, internal roaming settings of the rom, using a different prl etc.)

Couple things to help for sure.... GTalk is auto sign in.. So make sure it's signed out, Sync settings, Extend duration between them! (Emails to few hours instead of push (Obviously it'll sync when you open the app), Try running Juice defender, It'll disable data if screen off. (SMS comes through) Brightness, turn it down some, I'm running the Ktoonservative with the kernel.. Netting atleast 2 hours screen on, 11+ hours battery and still sitting about 60% remaining (most days) Those are the settings i'm using and things i'm doing. (I play games off and on, Text, read forums, news, facebook) also, ensure Media isn't running. (Not media server) it's known to eat some battery randomly. Just a few things off the top of my head to help.

Wifi or cellular, it doesn't matter as far as wakelocks are concerned.
Cellular data consumes more battery than wifi data.
Unless you disable data all together, using wifi is more efficient way to run your phone.

On you are not grasping my simple statement I never said WiFi want more efficient but it would be foolish to pretend it doesn't wake lock and kernel alarm it up. For one wpa pretty much requires it to communicate every so often. Other reason.... couldn't tell you why precisely but of you look then you will notice it does in fact create huge wake periods

I would suggest killing your mobile data, or for a more extreme test running in airplane mode with wifi on.
I personally get 20-30 hours at home browsing the web / texting / googling / etc over the weekend, maybe 18-20 when im out and about. But at work i get MAYBE 6 hours, with under 30 minutes scrren on and usually less and an hour awake. Why the huge difference? Mobile signal strength at home i keep mobile data off, and wifi on, and have ~ -75dbm signal strength. At work i have no wifi and ~ -110dbm and my phone is constantly trying to get a better signal.
Looking at your original post, what is "audioOut_2" and " PowerManagerService"

Question, is media server something that can be frozen in Titanium Backup?

[Q] Battery sleuthing - your input is requested

Hello,
I was wondering if you guys would be kind enough to help me figure out what has been going on with my battery lately.. First up, here is all the relevant info:
Phone: Galaxy Nexus GT-i9250 GSM
Network: T-Mobile USA
ROM: Paranoid Android 2.54 - this is based on 4.1.2 - NOT the latest 4.2.1
Kernel: Franco Kernel Milestone 6 <-- My battery issues only started after I switched to this kernel. I had to ditch the stock kernel than came with PA because it was slow as molasses.
Here is the battery drain that shows 43% of total battery was drained in 6 hours

Here are some more details that show how much time the phone was awake:
Partial wakelocks are shown here using BetterBatteryStats. I don't know what AudioOut_2 is but it's sucking down battery. Exchange is another battery hog evidently.. I don't understand why Google Plus is running, I NEVER open the program.
Here are the kernel wakelocks:
Here are the alarms that show which app is waking up the device how many times. LightFlow and Exchange seem to do this a lot. I have no idea why maps keeps waking my phone, I haven't opened Maps once or changed locations but the location service is relentless.
Here is CPU Spy showing that Deep Sleep is definitely working:
Please can anyone help me figure out why my battery drain is so out of control? I forgot to screenshot screen on time but it was less than 30 minutes. You can sort of see this from the graph on image #2.
Thank you in advance.

Bumping this in hopes that someone is able to help me figure this out.

it seems like your signal is fairly bad most of the time, that will drain your battery pretty bad since the device will try to seek better signal.
also, i would suggest you to upgrade to latest PA along with latest franco r361, I see a significant battery improvement after the upgrade.

light flow is keeping your phone awake as well.

Thanks. Yes the signal is not great at my office, but it hasn't changed in the last few months. What has changed however, is how drastically my battery is now dying, this is recent.
I would update to the the new PA with 4.2.1 but there are a few things I'm not ready to give up yet like the old toggles etc. Once the new PA builds some of those older features back in, I'll be upgrading for sure.

Yes it is, I don't know why it wakes up my phone so much. I tried checking the "reduce phone wakes" option, but that seems to miss notifications all the time.
Overall, even with not so great signal and light flow running, this battery drain just seems WAY too much, would you agree?

what is your screen on time?
and light flow has been known to kill battery. id honestly remove it.

How often do you charge the battery? Do you plug it in all the time? Do you run it dead all the time? Your battery may be getting shot out, happened to my wife's to the point it would not take a charge. New battery fixed it. Buy a battery of eBay for ten bucks. Worse comes to worse you have a backup battery if that wasn't the problem. Audio out only took 3.5% and most of the time was deep sleep. I think your battery is dying

I charge it at least once a day - every night. Sometimes I'll plug it in during the day if I know I'm going out in the evening just so it'll be topped off when I go out. But I thought charging these batteries a lot didn't affect their ability to hold a charge?
I'll definitely buy a new battery either way, hopefully that's what it is.
In case anyone else has any other insight, please do share in the meantime.

The more I think about it, the more I believe that Google Now could be a major culprit in draining battery. I'm going to try disabling it entirely to test. Do you have any experience with that by any chance? On how it affects battery?

You're right, I set it to "do not update your location". What does this do exactly? Looks promising though.

I have tried doing partition wipe cache and disabled most apps under auto start manager, unable to figure out what is causing this issue
I have no other issues on Asus Zenfone 2 and it is probably the best Android phone I have ever used, just this battery drain issues is irritating.
Lot of Zenfone 2 users have logged this issue on Zentalk forum but Asus support seems to be clueless about it, recent firmware update also failed to address this problem.

Me too
I think it depends on wi fi...
When I'm at work ZenFone connect to various AP and the battery drain is heavy....
But when I'm at home the battery seems to be normal, I can finish the day with 20% of battery from 17 to 21.
I see the battery is longer on 3g/4g than when i'm at work on wi fi

I think Zen Motion in settings specially touch gesture is one of the causes for battery drain issue...

Probably...but when I'm on 2.17 I don't see this battery drain....and I always have gesture, double tap to wake/sleep and zenmotion all gesture.
I see the battery drain increased when Asus have changed power profile

'Wifi Scanning always available' may cause battery drain. Recommend to turn off in not needed. To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. If battery still draining, recommend updating firmware to latest version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Hi Frank,
Regarding the Wi-Fi always on thing... Whenever I turn it off of always turns back on automatically.... Any advice.. I already am on 2.19 BTW..

Apologize for the delayed response. Strange, it shouldn't turn back on automatically. After latest firmware is applied, recommend doing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

Frank have you heard any rumors on if asus is working on the 5.1.1 update. The issue of Android us chewing up battery is a widely known issue for lollipop 5.0 and it impacts many different devices. Every thread I have read regarding this specific issue states that lollipop 5.1.1 resolves this issue.

Pathetic battery back up on ZenFone 2, hardly getting 3 hours screen time these days

My battery stats still reporting WiFi use when I have turned WiFi off and disabled always scanning. I don't get it!?
Edit: just figured this mystery out. It's because I had location set to high accuracy. If you set it to high accuracy or battery saving it scans WiFi even when WiFi is off. Put location to GPS only for the last ten minutes and voilà - no WiFi use in the battery stats

Spoke to soon, WiFi came back again on battery stats!???

Use better WiFi on/off by Chamonix. There is an xda thread for it plus it's available on playstore.

Do you see any major results with that application?

I read a lot about awful battery and screen on time before buying the zenfone 2. Surprisingly though with a bit of tweaking this has been one of the best phones I've owned in terms of battery life. I could have easily gotten 10 hours of screen on time i believe if I stayed in an area with stronger reception and turned off some background services like GPS. Here's some screenshots for anyone interested

You have 551 or 550? On what software version are you? And what do you mean with "bit of tweaking" I'm using heavly Amplify and Greenify, and I can get 4-5 SOT more or less..

I'm using the 551 with the latest .22 update. I'm not sure *exactly* what I did to fix the idle Android OS battery drain but I have underclocked to 2.0ghz, zen motion stuff is turned off, GPS is set to battery saving mode, all the stuff under Google settings >security is turned off, Asus cover off, detect battery draining apps in battery settings is off (its not very efficient as it just checks what is running in background, regardless of battery usage) and some more stuff that I can list later on when I have access to my computer

I have the same settings on mine (I also never use GPS so is set to OFF), I have more or less fixed Android OS drain WHILE in stadby (0,7%/h in airplane mode) but when I turn screen on battery goes down quick..we wait your answer if you can give us other tips!

hmm, Well for screen on time Underclocking should help the most. If you don't do any heavy gaming you can set it down to 1.8 without noticing a performance hit ( you could probably take it down to 1.5ghz but I haven't tested that thoroughly so there could be an impact). I use noop as the I/O scheduler but that probably doesn't make a difference. I don't use greenify but I do use servicely. I also stay far away from facebook and the messenger app as that has always caused me crazy battery drain but I know those are apps alot of people would rather not delete so its up to you. I use balance mode in power saver and also use Asus' built in auto start manager to disable most things at boot I don't need. Another thing that helps with wakelocks is to make sure you open the google settings app after you boot ( you dont have to do anything, just open and close. I don't get it either) it works for many people including myself.
Other then that I can't think of much else I do. If anything else comes to me ill be sure to let you guys know
