Android OS Killing my battery?

My phone has been off the charger for roughly 3 hours and my batter is already down to 66% .. I spent about 10 minutes in the market and that's about it.
Battery status looks like this-
Android OS 70%
Display 10%
Android System 5%
Cell Standby 4%
Phone Idle 3%
Market 2 %
Any ideas on what is going on with my android OS?
*Running completely stock*

Rooted phones have a few extra options like cpu settings unvolted kernel. Stock phones-try to lower you brightness, shorten screen time out, turn off gps and bluetooth. There is a app called juicedefinder that seems to help.

check what services are running maybe?
settings>applications>running services

You can click on Android OS and get a more detailed break down of what is using up the most juice in that subset... I am betting you downloaded an app at some point that is corrupt and running non-stop draining your battery.

I clicked on it from the battery status but it only lists CPU Total, Data Sent, and Data Received. Doesn't break out what programs are doing it.
Under the running services is there a way to see the programs power usage or perhaps an app that will do this?..
On a side note my battery is now down to 30% with it's only uses since it was at 66% was taking it out of standby every once in a while to see the battery usage. Android OS is now up to 73% of the usage..

You either have a high refresh rate for data on a running service, or you downloaded a program with crappy code that doesn't kill itself when not in use.
List your installed programs.

Odd... I am on a Desire ROM, but when I open up my system battery usage, AndroidOS isn't even showing, it has a long list of apps, and appears to be in order of battery usage. I could swear AndroidOS does the same.
Download Spare Parts from the market, then click on Usage Statistics to see which apps have been running the most, etc.

I am using Task Manager to autokill apps but I feel this tool is itself eating battery no??

How do you like this ??? ...(but: no WiFi/3G used !!)
Check out the battery & hours!

Yes.
Task manager are running service(battery eaters) that monitors and closes apps in saved states(not battery eaters) and other running services. It's counter intuitive to run autokill applications because it itself, is wasting battery killing stuff that doesn't need to be killed.
Task managers that autokill are good for applications that have ****ty code and don't close themselves, or for programs that hang up.
Nothing More
If you're autokill killing services alll day long, why are you even running the services? Just run then as needed.

my display is like 65/70% of the battery use

So you are using Cyanogen ROM
Try Emo or Desire Roms it should fix display battery problems

I've tried more taskkiller programs (ATM, Taskiller, etc) and came to the conclusion, that the ONLY auto task killer which actually SAVES battery (compared to setup w/o task killer program) is Task Panel. Don't ask me why/ how, but with TaskPanel my N1 is fast en lean, battery lasts about 130% of native (w/o/ TaskPanel).
Of course, question is whether task killer necessary, but as I use lots of widgets, programs, in my experience task killing helps to keep my N1 fast..

imm using modaco custom R13 rom
http://android.modaco.com/content/g...custom-rom-for-nexus-one-with-online-kitchen/
this one
this morning at 100% it was 8am
at 2PM im at 52% , its been 6hours with 3G on, light at 25%, everything else off.
with 30min music, 10min calling, some sms and a 50min TV show....
my iphone held quite a bit better

So after some systematic disabling of apps it seems the culprit was the Touch Input that came with the HTC_IME .. After disabling that I am back up to regular battery life and android OS is only using 2% of my battery again.

Sometimes the Android OS is stuck at 70% and the battery is drained really quickly. A reboot fix it. Next time I have to check what exactly is causing that Android OS is at 70% battery usage.

just to be sure, you're using nexus one? if so, can you elaborate more on what app or service you're talking about. thanks

that's weird because i am using the HTC IME keyboard and i have touch input running too, but my display takes up 90% of my battery all the time. must have been some weird glitch.

Yes this is a Nexus One running stock ROM.
It may have just been a fluke with the version I downloaded from this forum. I am going to install the new version as soon as I get around to it. Not sure how it did it but as soon as I disabled it my battery usage went back to normal.

I was having this same issue on a MyTouch 3G running a 1.6 Rom (TheOfficial), and it appears it's a common problem on the Droid as well from some research. I was using HTC_IME. I just switched back to the default android keyboard and will see if it fixes my battery drain issue.
(My thread in the mytouch devel forum got locked for some reason, even though I consider this a legitimate concern for ROM development, since it's a rather major and hard-to-find defect.)
UPDATE: the "Android OS" task has stopped being a problem after I switch from HTC_IME, but "Cell Standby" is now taking up 50% of the battery, so the battery still drains, but slightly 30% slower.

Expelling the Evo poor battery life myth!

Today I decided to do a real world test of the Evo's battery life. I used my phone the way I would normally use it on an other day. As for the phone itself, I am running the rom from the OTA update. The only changes that have been made is that I am using unrevoked root method so that I can use the Overclock Widget (marketplace) to turn the processor freq down to 245000 when the screen is off. I also use Advanced Task Killer to turn off apps that I am not using. I had bluetooth and gps turned on throughout the entirety of this test, wifi was on for about 3.5 hours. During this test I played a game for a short period of time, did some light web browsing, and had several phone conversations that totalled a little more than 2 hours. With doing all this, my battery lasted for a little more than 11 hours. That being said, under normal use the Evo should definitely last you throughout a full day.

Thanks for the info. I got my Evo yesterday and haven't been able to put it to through extreme testing yet

No problem. just kind of got tired of hearing how poor the battery life was. Even before using the overclock widget I was still getting decent battery life, but the overclock widget just put it over the top. To add to that, I don't normally talk for 2 hrs. on my phone during a normal day, so really a lot of that 29% battery drain from phone use wouldn't be there. The only thing I didn't use today was 4g (which I don't normally use unless I'm on the phone and need to use data).

Not sure what this proves or "dispells". When people (myself included until making some friendstream changes) are getting 6 hours out of a charge with light use, that is a real problem. You must not have friendstream syncing...if you did and did everything you just wrote about, your phone would be dead in 3 hours tops. Thanks for the info., but once again, people are havnig real issues with the battery...it's not made up.

If you are experiencing poor battery life then it is most likely attributed to not managing your apps properly (friendstream included). For example, without advanced task killer you will get a drastically different amount of battery life than if you have it. Then add to that, the way you configure advanced task killer can add a large amount of battery life compared to having advanced task killer without it being configured properly. Even with friendstream running you should still be able to get a decent amount of battery life (I am aware that it does use more juice), try having your facebook sync less often.

I totally agree I've been using my evo and been fine, I only really have it connected to power when I have it tethering. Besides that it lasts me not all day but while I'm at work (which is the most important part) I get a good 9-10 hours out of it before I really need to charge. It should also be noted that I use locale to switch BT and wifi off when I'm not in an area to take advantage of them.

While that is possible I think the majority of the problem rests with the user's mismanagement of apps. I have seen way to many posts from people declaring the battery life to be so horrible, only to make a few changes and then turn around and say how much better it got. If that person had a bad battery then the battery would still have been bad, it wouldn't just start being good. That said, it is very possible that there are people with bad batteries. I just think that most of the people have good batteries and bad phone management.

I did pretty much the same thing. I have the O/C widget to set the frequency to 245000 when the screen is off and also have Advance Task Manager configured to close apps I'm not using. Helps out a lot and I usually get around 12~14 hours on a charge.

While I completely understand what you are saying, I can't really agree that b/c someone is not getting a full day out of their phone it is b/c of poor app management. While deleting facebook for sense, then reinstalling with only contacts synced fixed everything for me, the fact that you have to go through the phone with a fine tooth comb to get it to run more than 6 hours at a time is pretty silly. While doing that stuff is fine for me and most on this forum, it will undoubtedly turn a lot of non-techie people off from this phone...especially with Sprint doing their new 30 day full refund policy.
It's all good though, just plugged my phone in after 19 hours...playing with it most of the day.

I use advanced task killer and turned off sync for apps I dont use. At 65% used pandora (in 4g for about an hour), browsed several sites, made phone calls, text, emailed. All the normal stuff. Took my phone off the charger 15 hours ago.
Prior to using advanced task killer I would be to about 18% right now. So for those saying that task managers kill more battery power my phone seems to do the exact opposite.

Task killers really only help if you have an app that would normally be giving you higher than usual wake time (the calendar comes to mind). At the start of every boot I always make sure to kill everything so only essential apps and those I use are running. I don't use any kind of auto kill.

It is no longer recommended that a task killer be used. It may result in poor phone performance.

After i rooted with Toasts method, installed OMJ's rom removing all of the sprintware and added the OverClockWidget to tweak the processor, i was able to go a full 32 hours without charging. i had gps and bluetooth on the whole time and wifi on for several hours. i made calls, sent texts, took pictures, basically normal usage.

Just to add to all this. Bad battery isnt just a HTC Evo problem. Go read the forums of almost every android phone released and they all report the same things (in the beginning). Someone that has had a android phone in the past probably hasnt said much about battery. There are so many things you can do to increase battery.
1. manage your apps. Exit them instead of leaving them running (press back button until the app closes, or some apps you can Menu> exit) Pressing home doesnt close the app, it only takes you to the homescreen. Also change the sync times of all your apps/widgets. If you dont use gmail or google calendar, then uncheck the "sync" in Menu>accounts & sync> google. One last thing use a task manager (not recommended by some devs) I use it to end tasks of apps that use data, or ones that i use maybe once a day or once a week, i dont need them cached for quick returning, so i end the task all together. I ignore apps so they dont end that i use very frequently or ones that dont use data or run in the background.
2. Calibrate your battery once like so.. Charge your phone to 100% and then use your phone like normal until its so dead it shuts off by itself. Dont plug it into the computer or wall charger in that time. Then once it shuts off, plug the phone into a wall charger and charge it till its 100% again. After that, plug and play as much as you want.
3. Buy a car charger, usb cord for the comp, and maybe another wall charger. Buy an extra battery or extended battery. Doing the above and adding these to them, youll have a huge increase in battery.
I have an htc hero and i can get well over 12 hours of use by just watching what syncs and what uses data. And i use my phone alot, and wake it up a ton to check for notifications.
I use a friends Evo so im not new to the device and I understand its a different phone.
Stock htc phones come with a lot of stuff preinstalled and widgets. When signing into them with your accounts the sync times are usually pretty high, some like every 15mins. Watch what you are doing with the phone and youll have normal battery life.

i avg 18 -19 hours per charge so im very happy

aaaaah ok now I know who is the idiot Dylan here. Thanks. What a dumbass know-it-all.

I think some people are getting poor battery life because intermittent signal. I know this was the case for me. When I go to a friends house that I barely have signal, the phone constantly tries to find signal or goes into roaming. It would drain the battery fast. When I was in good signal area it seemed to last quite a while. Just saying that it is more than just running apps that cause poor battery.

Also if you will not use the internet turn off the mobile network, put the widget in your screen. You can receive calls but the internet is off.

You make a very good point. Weak/no signal areas will drain your battery (as with any phone) very quickly due to the phone constantly scanning for signal. Not really much you can due about that other than turning your phone radio off or switching carriers lol. One thing I've read in the Dev forum that may help you is to change your prl to the Alltell/Verizon prl. Some people have reported that this works well in low signal areas.

Task Killers - Improving or reducing battery life?

Hi!
I read a lot about increasing the battery life of X10, and opinions on task killers are sometimes completely contrary.
Right now I'm using Advanced Task Killer to kill apps in background, but I can't say my battery life increased drastically.
So what do you think, Task Killers yes or no? And if no - what do you use for task managing?

Well...
According to JuicePlotter, I gain from 20hrs to 36hrs battery lifetime, while using the free App "Task Manager".
I set most of all Apps / Processes to AutoKill.
Over here I began a list of all processes, running on X10.
But it was ignored after root was achieved
<--- Push me real hard -->

My experience with Task Manager was fairly flat.. however, using Advanced Task Killer definitely reduced my battery life.. not significantly, but noticibly. And worse than that.. it slowed my phone down.. it was killing things that the phone needed, so the phone had to keep restarting them all the time..

Do you use it with the new build and what frequency do you have it set to?
I heard that if you set it to screen off, it might make things a little worst? (again with the new rom build)

I killed my task killers and seem to have as good, if not better battery life...
The only thing I can say about a task killer is that there might be an app that drains battery which you don't know is still open in the background...
For example!
This morning I was playing with Abduction (world attack), switched to home and forgot about it... found my battery had dropped to 68% from 86% in the same time it would have dropped to about 85% (this was after I stopped playing), so it would seem AWA uses a bit of battery while idle (even check the battery status, and it's right up the top as the most power hungry program)
So with a task killer I could have killed it, or without a task killer, I could have just closed it... what's the better option...? close it properly, I say.
A good task switcher will also show what you have running that might be idle - use one of those instead of a task killer.

Task killing is the dumb solution for battery improvement. It works only if you have and offending process sucking your battery, but it is like cutting your hand if you have a pain to a finger.

Lag fix battery fix

After I did he market place lag fix I found my battery drained a little more than usual. I downloaded a program called memory task cleaner. This will also allow you to set auto kill on apps you dont want always running n the back ground. simply add as many programs as you dont use or want in the back ground running to the auto kill list. Set the safety level to medium in options in auto kill screen. also set intervals of auto kill to every 2 minutes. auto kill when screen off as well.
There you go. You should notice the phone is back to normal with the battery life as well as if your like me, no need for tee nav or blutooth and things like that you will notice the battery may even last longer.
Let me know your results. Settings so fourth.
By the way there will be plenty to auto kil. the galaxy s runs alot of programs all the time for no reason.

so far so good
I had my phone fully charged and tried this so far so good! Ill report more when I can test more. But it has definitely lasted longer so far. about an hour off the charger using wifi online and all, still full batt!
Lets hope this fixes it or Ill have to go back to stock.

So instead you have a program running that every two minutes kills running programs that will start again anyways, beginning the cycle all over again?
Edit: and the way android works, "running" is poor word choice

What its the difference between this and ATK? I'm pretty sure this will so more harm than good.
Sent from my SGH-T959 using XDA App

Oh, nice OP. Now you have programs constantly fighting themselves to run/kill each other. So now instead of the Android OS taking care of itself, you have these programs sucking down CPU cycles and battery juice.
Dump the autokiller and use ATK to manually kill things if you don't want them running. I get about 35hr of standby time.
Edit: If you really want to be smarter than the Android OS, uninstall the app/widget that's sucking down your battery.

Help guys, about battery consumption

I have upgraded to GB firmware recently, and the battery consumption now is quite bad. So i use Juice Defender(free), it says the battery improved by 1.4X, but overnight consumption in standby mode could cost up to 40%, is there any ways to solve this?
Thanks
* I not sure should i post it here or QnA, please shift if necessary.

One suggestion is to stop using Juice Defender. I think it is keeping the the phone out of deep sleep, causing the overnight battery drain. Also, check if your wifi is set to turn off at screen off (Settings > Wifi > Wifi > [menu > advanced] > Wifi Sleep Policy). Turning off mobile data, or switching to 2g, will also help. Background data and syncing will also reduce battery life.
And yes, it should have been in Q&A.

I dont use data nor sync, i will only on the wifi if i need them, so i not sure why they drained so fast during the night since i off them, the day was ok(maybe due to JD).
Not sure is there any other alternative to help with this situation if i dont use JD?

Check your CPU usage using CPU spy overnight. Your phone should spend at least 90% in deep sleep. If not then something is keeping your phone awake burning up battery.

The original data wont affect anything? Because the data now are quite low on the deep sleep. only 30over %.

Before you go to bed, reboot phone and then leave it. Check CPU when you wake.

Just my 2 cents,
Juice Defender made my phone run extremely HOT
and the battery was draining significantly faster than usual.
Green Power Free is a good and free alternative, less features (only controls data & WiFi) but much easier to set-up too.
And it doesn't hurt battery life all that much.
Bear in mind though, any app that runs constantly in the background
and manages core phone functions, will impact your battery and CPU usage.
In my opinion, an APN and WiFi on/off widgets come quite handy.

Actually i dont use data at all, so data ia off all the time. Wifi i used it at times, but i do off it when not in use. Sync i do not put it as auto too. I kill task quite often too.
EDIT: that app like dont do much, i didnt change change the setting at all, somewhat my basic settings. =X

DON'T.
See, most -if not all- task killers use a very "nasty" way to kill apps
and the system thinks that they crashed and immediately restarts them.
Which leads to increased CPU usage and battery drain.
Don't kill tasks, let Android handle its memory.
Does Android tell you what to eat and when?
Why should you tell it how to function?
If you have many useless apps that include background services,
(and I bet you have, since you are not using data and you installed Juice Defender! hehehe )
consider uninstalling them to "clean up" your phone.

No, programs in the kill task list can be in either one of 5 states.
Read this:
Android
On Android, apps are suspended when they are no longer visible to the user. Suspended means the app is still in memory, but it is frozen. No processing or event handling happens. If the system needs additional memory, the least-frequently used apps that are suspended (in the background) have their state saved to persistent storage and are then killed, freeing up their memory. To the user though, those apps still appear to be in the background. When they are brought to the foreground to be used again, they are restarted and passed an object containing their last state so they can be restored to look exactly as the user left them.
If an app requires processing while in the background, then it must also have a service component. A service on Android is like a separate small application that runs without a user interface in the background (though not actually a separate application). The service has a server/client relationship with the app. It performs whatever action an app needs it to continue performing should the app be suspended. For example, the service might handle all uploading, so if an app is placed in the background while an upload is in progress, the upload continues. Or, like Pandora, the service might handle all network streaming and audio output with the app only acting as the front-end controls. Unlike apps, services are not suspended or killed (except in extreme low-memory conditions).

So, no need for task-killers, you are only making things worse. Trust me on that.
