I used my phone for a 10 minute phonecall this morning, I did a little bit of wireless tethering to download some ppt files for my mba class on my laptop, and then I just did some basic surfing on the phone and using the xda app.
My battery level was at 80 at about 12:15 pm. I left for a little bit, leaving the phone where it was, and when I got back around 1:30ish, I looked at the phone and the battery level was 70. That's very uncommon and I was really surprised that it had dropped more than 1% or so in such a short time. And within a few seconds my phone just rebooted by itself. And when it came back up, it was running VERY VERY sluggish, and I opened up system panel, and my CPU consumption was at 90% or above. I had to reboot into recovery and wipe dalvik cache and cache, now the phone is running like normal.
I looked at my system panel monitoring data which I had running, and I'm posting the screenshots of the historical data.
It seems something suddenly happened to the system. I can't figure out what it is. Can anybody point me in the right direction?
Check the logcat.
If you see a message saying something like "Can't read CPU frequency linked list - next isn't in the list" or something like that repeating endlessly as an error, and you happen to use iR's kernel, then it makes 2 of us and you can show him the logcat to debug.
I wanted to debug it, but I don't seem to find any time.
I'm using wild monks kernel that's listed in my signature. How does one do a log cat anyway?

Wildmonks' kernels are based on iR's source, if I'm not mistaken.
Go to Market, search "logcat".

I see the battery drop from 50% to 0....did you change anything with the battery calibration app?
I set my battery health to 100% from 94% and my phone switched off at ~25%. Try wiping battery stats.
Happening to me too. If you click on System you'll see it's really the suspend process. Typically on my N1 there is nothing in the log.
See here for further discussion: http://code.google.com/p/android/issues/detail?id=11126, "suspend" process runs continually in background at ~40% CPU on HTC EVO 4G
I had this problem too.after I installed look out on my phone, I notice that my phones battery was dropping significantly fast. I thought it was the look out app that drain the battery since it's a security app and should be running constantly. But it's not though cuz I installed the app on my wifes g2 too and hers is fine. Hers is stock btw and mine is running cm6.1. But after 2 days and few time rebooting it, it's fine and normal now.
I usually make it through one heavy using day, but when the problem exist it can barely make through half a day. I start my day at 8 and stop at 6

Anybody come up with anything on this yet??
I can confirm this issue happens with a whole bunch of iR's and WM's kernels. On the other hand, never happened on stock Enomther's kernel.
You can use OS monitor to see logcat or even dmesg log for battery stuff too. And you can use that app to export both logs to memory card whenever you want. I do that all the time to analyze my log from a computer when testing the battery calibrator app when developing new one.
No clue why that CPU is happening though. I, too, purchased system panel and It's by far the best app on my phone.
I had this once. It was a corrupt photo on my SD card. I formatted it, restored some files, and it never happened again.
Unless you really go through all your logs line by line I don't think you can figure this out. This includes both logcat and dmesg.

How much total battery life were you getting before and after the fix?
I'm running attn1's rom and I get excellent battery life, like literally 1.5-2 full days of average use before it goes down to 0.

I believe nandroid is a full backup, almost like an image. So if you needed to recover it it should restore your phone to how it was when you ran nandroid.
When you restore a nandroid backup everything returns to exactly how it was when you did the backup, I.e.homescreen, unread texts, notifications, settings apps and all.

Which Rom manager did you use? I got one from the market and installed it. When I attempted to fix permissions, it did nothing. BTW my Aria is rooted and has sideload capabilities. Thanks.
assuming this does work anyone have a theory on why?
Quick question guys. How long does your phone take to fully charge? I've had my phone today from 8am to 7pm
Plugged it in and after being plugged in for about an hour and fourty min. It says it is at 100% but the light is still red. I did repair permissions and rebooted I'll see if it helps tomorrow.

How do you guys do the fix permissions thing? I have the liberated Rom and my battery only last like 7 hours
Sent from my HTC Liberty using XDA App
you have to use Rom Manager, download it from the market. you have to have clockwork recovery installed also. Now 7 hours for battery life, is that under heavy, moderate or light use? if thats under heavy use thats not bad at all. also depends on what widgets your using and how your phone syncs, updates weather etc. theres alot you can do to optimize battery life without the permission fix, if it even works?.

it depends on if im using my phone while its charging, it can take anywhere from 1-3 hours, or more if it gets hot and stops charging. and what percent did you start charging your phone at? from like 15% to a full charge without using my phone, itll take approximately about an hour and a half

It was 15% and it took ~2 hours to reach 100% and turn the led green. so i basically got 11 hours with medium heavy use which is pretty good.

General Battery tips.
Remember you are running a lithium ion battery, that means it is important to get a full charge on the first charge, and also charge it as often as possible. Letting it often get to the critical state can have long term negative effects on battery life. Such is the limit of our battery tech.
Optimize how many apps you have running, use advanced task killer etc. I also heavily recommend that you change how often your phone looks for updates, facebook notifications etc.
Turn gps on only when you need it.
Ditto for wireless.
I let my phone auto the brightness of the screen.
I generally get 2-3 days battery life, I talk for approx 1 hr a day. I watch videos/ play emulators for 1hr a day and I frequently text, update calendar information, and setup checklists.
As far as permissions go, chances are if you declined on many of them, some of your apps can no longer check for updates etc. So you are suddenly getting the battery life I get by making sure my apps are always dead unless I need them.
Also remember, many apps turn on automatically when you restart your phone, so run the app killer when you boot.
Good luck.
I have read little about this issue . Instead of renaming or deleting files can we make auto booting script to kill this process so it will no longer looking for a mobile data ?
I have no android skills so am asking somebody who have it. Maybe there is other safe way to ged ride of that battery eating cell standby process
Proudy owner of iconia
Pawel
PS
I have try
(Without doing nothing 50% SCREEN AND WIFI TOGETHER 40 % after change a charg iconia to 100 % and wiape battery stats)
2g/3g mobile data switching best results cel standby takkes only 35% battery
Kill mobile data and prevent to run almost same thing
Cheat with airplne mode same thing
Try to download from market a.k.a batery saver for acer iconia without any results (thor mod with i have is based on assus transformer and market shows incompatible version?)
Dear Pavel,
this is a rather old issue, solved long time ago. You can just add the following lines in your build.prop file, located in the system folder:
ro.carrier=wifi-only
Thor's ROM features this tweak by default so you don't have to do anything - no cell standby.
Well thor rom have this line indeed. And when U check settings about tablet battery indeed isnot showing .
When U install any other app to show battery stats actually shows cell standby and phone idle. I using norton utilities but few other ones shows.
I left for a night tablet screen off, gps off , wi fi on, airplanemode on and after 6h i have 15 % drop down. 8 H on my iconia possible when everithing is off.

If your tablet is new did you fully charge and then discharge the battery to about where it auto shuts off.

There are a couple of things to mention. If you are running an over clocked processor, this will of course use more battery power. Especially with thors roms, because the last time I looked, depending on version, it installed over clocked to 1.5ghz. If you don't need that much, try setting it to 1.2 for example.
Apps that are always running and synching. Things like weather apps, mail, fb, etc. And... those lovely battery apps (a waste of time). And this also includes Norton, as it runs as a process. All of these use battery power.
And as briandigital said, let the battery get a few full changes. Usually takes them about a week to settle down.
I agree with U. Those apps using battery. For example weather widget 0.5 % or norton 0.5 % but still shows 60 + % cell standby or 2% phone idle. wifi over night 30 % with checking mail every 15 min.
Over Clocking got nothing to do with this (1000 on screen on 400 on off) system proces phone is running all the time draining battery.
I have thor 14.2 mod and to get 100 % shure I flash again kernel and dubble chec for wifi-only line.
Wipe battery stats and 10 min after cell stanby 30 % after 30 back to 63 %
Or 5 diffrent apps from market are wrong showing cell standby and system process phone working and draining battery or this all solutins are not really working. If it not showing on /settings /battery is not mean process is not working
Anybody know how to kill that process and prevent to run ?
so can write small script to kill it"

I'll ask you a silly question.
And only because I didn't see it stated anywhere (or I missed it)
Are you running an A500? or an A501?
3g USB Dongle?
Did you run any "update patches" concerning 3g Dongle support?
Reason I ask, is that I did some of the testing for the kernel version you are using. (3.9r3). And frankly, I haven't heard a lot of 500 users complain about "cell standby" with the 14Rom. In fact the combo should be giving you extremely good battery life.
You said it only shows cell standby when using some other different application? I might suggest the app is not telling the truth.
Typically, losing 10% overnight with wifi on, is pretty normal. During testing, I lost 8% on internal 3g, and about 10 or 11 with Wifi. FB and Mail not's set to 1hr intervals. WX at 3hrs.
The fact you still have the menu system for mobile networks (2g/3g) is very puzzling......

You should re-think about posting on Thor's site. He's typically pretty responsive. Unless it's a stupid question, or somebody's not nice.
The cell standby issue is an old one. It's because the 500 and 501 share the same hardware with the exception of internal 3g for the 501. And because of that, the share mostly the same OS code.
Thors rom, was based on the asus transformer. I don't run it, as it doesnt fully support internal 3g.
It's possible, that the process is still running, only hidden from view based on the images you supplied with the modified build.prop set to wifi-only.
In this case, I would ask you again, to post the issue on Thors FORUM under the Rom ver 14 topic. It may take him a day to answer, as he's working on ICS right now.
In the meantime, here at xda in the a500 forum, there are several "older" topics covering cell standby on the a500. One of the fixes at the time, was to "freeze" the telephoney.apk (get some error messages) then reboot.
Just do a search for cell standby, and you'll find them. I found them earlier today through Google (but can't remember where), so you should be able to do the same.
Well I did some research before I bother U and other solutions is to rename / remove phone.apk witch may solid brick my acer. Am wonder if I rename it and hard reset can I be able go to recovery ? And restore prev backup or this is gonna be a perm brick
Sent from my HTC Vision using xda premium
Well Pavil, those posts are a little old.
And, sometimes people call things a "brick" when they really don't know what a brick is
BEFORE I would rename any apps, I would try this, Install Titanium backup. Once installed, and root granted of course, Select the telephony apk, then do a "freeze" on it. Reboot and check things. You may want to freeze those other couple apk's if it doesn't fix it. You will probably get some error messages when you first freeze it, but ignore it, and reboot.
But BEFORE you go freezing things, do a recovery backup first This way, you can get back to where you were before freezing.
Then see how things go.
EDIT. Stop using battery apps designed for phones. They may run on Honeycomb, but if they were designed for devices that have a functioning radio, they know no better than to display an erronous stat.
But honestly, battery stats in android are somewhat misinterpreted.
Example. If your device used 10% power. And the stat says Display used 80%, It means that of that 10%, the display was responsible for 80% of it. Not 80% total battery power.
In the meantime, I see you didn't post on thors site? Ok, I'm on good terms with him, so I'll pose the question to him.

It appears from your screen shots that you don't have your wifi set to disconnect when your screen goes off. I could be mistaken, but if it's not, changing that will help battery life immensely

Yeah, no sense in messing things up. A pity I don't have an a500 or I'd test it myself.
You could try flashing one of the other roms, and see if the result is the same. For example Taboonay. I ran it for quite awhile with Thors 3.9r3 kernel. Or you can use the kernel it comes with.
Answer from Thor is that he's not aware of the cell.standby issue as nobody else has mentioned it, and all his stuff now is set up for ICS, so he doesn't have the time to check it out.
So, maybe you just have to live with it. Seems your battery life is ok, so I would just ignore it for now.
Did you wipe your battery stats from CWM before flashing?... And by the way thor's ROM has CPU clock set to 1.2 GHz by default.
p. s. Moscow Desire is right about apps made for phones.

Yeah, he had to back off the original cpu install recently due to a couple users couldn't flash at that speed (1.5). Not all CPU's are made equal.
(the real issue here, is the old "cell standby" issue that a500's had in the past)
But again, like drkalo affirms, you shouldn't be using battery apps that were designed for phones running android 2.3. I suspect (considering nobody else using Thors roms complain about cell standby), that the phone battery apps have this hard coded, and expect it to be there, so it displays a random percentage. Probably because it see's the phone apk's in the OS and naturally assumes it needs to display something.
Yes, the apps will mostly function on Honeycomb, but, are they really made for tablets? Probably not. (even if they say it does).

So what to use to check ral battery / process usage?
Sent from my EPAD using xda premium
Personally Pavil, I do not use one. Except what comes in the rom. There's really no need to get anything else. And frankly, I don't hear a lot about folks running 3rd party battery apps on their tablets. So I'm not going to be much help on suggesting one. I just know most of the task and battery apps, were designed for phones on android 2.3.
I gave up on things like battery apps, task killers, task monitors and the likes a long time ago. I learned to manage things on my own like most others do. There's no reason, once you learn a little about how android works, to add apps that take even more resources.
Bottom line, you can have every app in the world to monitor things, but what really matters, is what the "actual" battery life is.
For example, I can go 12hrs with normal usage, and still have 60%. This includes internet, sms, mail a few times, maybe some video for an hour. It depends.
Or, I can play angry birds 7 hrs straight before recharge. Not bad! And I run my processor at 1500ghz.
You can instal a cpu app, like cpumaster, and set profiles based on how much battery you have left. I typicaly set mine to start at 1500ghz, then do 2 extras to down the speed based on battery. When I use them, I can run for almost 3 days with normal usage. I do this when I know I will be camping with no electricity.
I have 4 of these profiles on my phone, and the longest I lasted, was almost 4 days before recharge.
Wish I could help you more.
It didn't used to be like this. But now I get a pretty bad drain from Android System. It would be the second highest battery consumer, and would be using the CPU for quite a lot.

I have the exact same list of packages for Android System. Right now my phone's been on for an hour and it's at 21%, with a CPU total of 15 mins and it kept my phone awake for 4 minutes.
I dunno why it's like this all of a sudden. A week ago it was completely fine.
The thing is, I did clean re-flashes already and it still does that. I even wiped system. How do I properly reset my phone to get a clean slate? Should I RMA my phone if this issue doesn't go away?
Edit:
Just flashed MiNCO v6, and the drain seems to subside a little bit, but I need more time with my phone to judge better. Sigh, I'm missing CM's quick reply feature already!

It's not a hardware issue. The longer the phone is on, the lower % the Android System will be at (obviously lol) because the other stuff is averaging it out. You can also ry changing your kernel.
About the messaging quick reply, just replace MiNCO's mms.apk with CM's.

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!
If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.
Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.
I'll reattach the image in a second
Ah, you won't be able to see any links till I've gone past 10 posts. Back in a bit then, ha.

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

My android system has never been that high, regardless if I used the phone for 10 minutes or 10 seconds , or not at all.

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

I never told him to install a kernel. The advice I gave is to do a reset then I asked if he was rooted or running a custom rom or kernel because that might of been the problem.

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!
Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.

The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.
This kept my phone awake for an hour. Anyone know what this is?

Indeed. You can see this yourself within BBS (or other similar applications) by changed the point at which you wish to view statistics. For example, set it to list all events since the device was booted and it will show up. Now change this to only view events since the device was last unplugged off the charger. Now it's no longer there and since it's only happening while the device is charging, it's nothing to worry over.
I haven't researched what this service is though, but combined with the logic of what I started and what NervGaz said (awesome name the easy), I'm certain that it isn't having any ill effect on battery like all. I started monitoring battery consumption again street the OTA KitKat update because of several complaints I read about and was trying to help then out as MANY of them were suggesting just to do a factory reset and I had jump and say something because a factory reset is a drastic last measure attempt and quite honestly told them that a reset won't help a thing since they will go back to the same habits as before, meaning installing the same battery sucking applications (*cough* Facebook) or have apps such that set to sync all the time, etc.
Even if it was an issue brought on by a bad KitKat installation, the phone can always be fixed (with the knowledge i guess) without resorting to a factory reset. I've never had to perform one on my life, even now using my unrooted replacements G2. Never got around to rooting this one and also currently using apps which require me to remain unrooted. Now, being that I'm unrooted now, there could be the small chance of a system file getting corrupted etc that I wouldn't be able to fix, but if that happened I'd just root, fix the issue, and unroot.
Kind of went of track there, most likely due to the fact that performing a factory reset is always thrown around as the first step in trying to solve any issue on the phone. In rare cases like a corrupted file in a directory you can't access and you don't want to out can't root your phone, then yes. The Verizon telephone service people (I don't like giving them a title...some are very good at what they do but...we won't go there) are famously guilty for using resets the magic portion that cures all ailments.
Anyways, the point that I was trying to make before going on that rant was those posts on the other forum was what prompted me to investigate battery concerns, because from what I thought, KitKat was supposed to improve on battery consumption by (no clue the accuracy that numbers as I don't have an official source) up to 20%.
On KitKat I've been getting around 5-6 hours of battery life. So far I'm at 37% battery left, with 4 hours and 17 minutes since being unplugged with an estimated 1 hour and 57 minutes left. Doesn't sound very good does it for the average G2 does it? Not until you realize screen on time has been 4 hours and 6 minutes, with my main activities being surfing forums and typing a LOT as well as some time dedicated to my favorite mobile game at the moment which also happens to use more battery than ant other game I've played...Avabel Online (IgN is Styrael if anyone plays - lvl 64 gunslinger)
I haven't run across anything out of the ordinary yet when it comes to battery life but kids still early. Sorry for the long post there, I think I'll get back to Avabel. I hope the 100% exp, jexp (job experience), and drop rare bonuses are still in effect.
