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.

What am I doing wrong here?

Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.

After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

Discharing a battery is bad isnt it?

Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!

Also fully discharging your battery every now and then is actually beneficial for your battery.

Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Where can i find the timout setting for the lock?

Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?

I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.

For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.

Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.
Terul

I dont get it........BATTERY DOESNT LAST FOR ****!

So i noticed on my stock battery i get about 10 hours of battery life, when im really not even using it at all besides checking it on my breaks or lunch. For instance i had a full charge at 4:07 pm , disconnected and now have a 70percent charge at 5:44..? really WTF is going on with this phone..? I havent done **** on it but browse. I even bought the verizon extended battery and that thing doesnt last as long as i thought, it dies down in about 8-10 hours tops as well.. Is there something im missing here?
I dont run gps often and neither wifi or bluetooth. Just texting and getting online every now and then....
i do have advanced task manager and do notice almost every program running all the time although i kill it when the programs when i jump on my phone....is this normal? wtf is going on with this thing?

Check for things updating frequently like twitter. Also don't kill them apps they will restart using battery to start it. Just let them run, they actually hibernate till needed.. don't close them.. that's probably killing your battery.

There is a lot of bloat ware that runs in back ground unless you root and uninstall. That is the one think I hate about these phones. I wish I could uninstall the bloat ware with out rooting. Anyway download advanced task killer and set it to kill programs whenever screen is blank. It will save some battery life. I get a day out of mine easy and I talk for at least an hour text at least 20+ a day, have it auto check every 5 min for 2 emails and have quite a few widgets running and surf at least 10 minutes...

I was really hating the battery at first. So much that I bought two non oem batteries from ebay. However, since I rooted AND loaded leaked froyo AND loaded deodexed, re rooted froyo leak through koush's recovery, I am getting through the day with 30% or more when I plug back in at night. The only extra charge is in the car dock for 30 minutes on my ride home from work. Try those steps, and rename bloat. Get rid of atk. I get much better battery life without it.
Just my experience, hopefully you figure it out. I'm a fairly heavy user and love this device.

I have had battery issues in the past. Now I am making it through the day comfortably. I am at 12 hours and 45 minutes and have 40% battery left. That is with wifi on all day. I am not using any task killers. All I did was calibrate the battery. Here is the link I used and it works great. DO NOT DO THE VARIATION. IT DIDN'T WORK FOR ME. Do the long version.

Also those china batts go to 10 percent in about 5 hrs but last for another 5...its odd but they are my backups anyway.

Look. The real issues are simple, the display is quite large and pulls more backlight than it needs. Not only that, but the CPU pulls more power than it needs too. I turned off automatic backlight and set it to the lowest setting. I rooted my phone and use setCPU in order to scale back the processor when it's not needed.
Also, web browsing on a 3G network is much more energy consuming. It's just a fact.
As for the apps, they activate because you have widgets on your home screen. If you want to reduce the running programs, replace unneeded widgets with shortcuts. The less programs running, the less power needed for RAM and CPU function.
What do I get in return for all of my modifications? I can use my phone for about 2 days without having to charge.

I can easily go 48 hours on my extended battery with the right settings... YEs this is with 3G on all of the time.
SetCPU is underclocking or "ON DEMAND", I have deleted most apps that come with the phone that one would never use, backlight is on low usually...
If you are sure that you have all of these settings set and still aren't seeing improvement, go to verizon and have them replace your batt.....

I can go 48 hours on the extended battery and I'm not using SetCPU and I typically leave the screen on auto brightness (though I guess I occasionally turn it down).
Yesterday's usage:
Unplugged the phone around 7:30am. Read emails for about 20 minutes in the morning, checked the weather. Listened to some music on my bluetooth headphones on the way to work, maybe 30 minutes. Started up Appbrain on the phone and downloaded/installed the apps over 3G. At lunch, I listened to more music on the way home, browsed the internet for maybe another 30 minutes while I ate, and listened to music on the way back (all bluetooth).
Showed a few coworkers some of my apps, so another 20 minutes or so with the screen on. Occasional email/text throughout the rest of the day.
At home, I sporadically pick up the phone and browse the internet/read emails/send texts. Easily a solid hour+ of browsing. Played a couple games and downloaded a couple more apps.
When I went to bed and plugged the phone in, around 11pm, my battery was at 50%.
More information about my phone:
- The only radio I toggle on and off is Wifi. Everything else stays on all the time. Wifi goes on when I get home.
- Widgets that update themselves are: a calendar widget, a Google Tasks widget, a sports score widget and a weather widget. All widgets with configurable timers are set to update in 30 minute intervals.
- I have ATK installed but only to let me manually kill processes, it has no auto killing intervals set.
- I am running Launcher Pro Plus. Before I installed LPP, I cleared off my entire Blur desktop - there is nothing on it.
- I am rooted and have removed most of the common bloatware - nothing crazy, just the things like CityID, Amazon apps, Blockbuster, etc.
Hope that information helps someone.

Speaking of extended battery and long life, I just got 34 hours out of mine and it was only down to 30%.
I'm using Juice Defender, toggling data for 2m every 15m AND completely shutting off data when I sleep, 1a-7a.
I don't have a lot of background updating apps either, that seems to be a big thing. After figuring out what works and what doesn't regarding battery life, I can use my phone as I please and not worry about batt life.

This thread is crazy my battery last all day and im on the internet atleast 4 hours a day and receive and make multiple phone calls, and text and stuff [email protected] 12.5 hours with 60% of battery left. I did condition the battery when i first got the phone i let it fully discharge 5 times

Bought the 1750mah extended battery. First 6 days the battery didn't last that long but the instructions did say do 8 full charges which last about 7-8 hours. I did that and over the weekend I saw awesome battery life.
Unplugged at 8am. At 10 pm I was at 40% life. That was with some light web browsing, book reading.
One thing that makes a HUGE difference. Are you in a constant 3g area? If your phone drops to 2g/1g and it can't find a signal, it will burn through your battery like crazy.
My work building is a verizon void and I get virtually no signal. I get in at 7am. By the time I leave at 4 pm, I'm down to 15% battery. I do not use a task killer. I keep my screens to a minimum. The only thing that updates are facebook posts and beautiful widget which updates every 3 hours. I use the smart battery profile.

Don't you a task killer they kill your battery faster. This is not a windows phone, its based off of linix. applications don't stay running in the background, they hibernate so there not using a lot of resources. when you kill them there just going to restart all at the same time, which slows your phone down, and kills your battery. I was getting about 11 hours on one charge using a task killer, now using it more im getting at-least 14-15 hours. plus if you have your task killer set to high it will randomly reboot your phone, even when your using it....

I dropped my task killer and my battery life is now better. I've had my X off the charger for 6 hours and only recently got to 80%.

My battery life is amazing. I left for work around 6 am yesterday with 100%. Through out the day I talk for about 2 hours, used the internet for about 3 hours straight, listed to music for 1 hour, pandora for 1 hour, and navigation for almost an hour. My battery was at 20% at 11 pm.

it calculates use/time so the percentage is a simple variable that will change as soon as you take a idle phone and start using it.

Don't know if this has anything to do with it but I did install a task killer from the market with the red android icon. Maybe this has something to do with it?

Probably best that you remove that.

The problem with task killers is that when you end those processes most of them automatically start back up which of course uses more power to do so. So say for example you get one of those automatic task killers then all day long your phone is ending processes and then restarting them.
Froyo has sort of a built in task killer which you can use to close apps that aren't working probably or that you notice are draining your battery.

You shouldn't use automatic task killers, as others have already stated above me. Another reason is that the task killers themselves are wasting and using system resources and cpu cycles.
What I generally do to keep my phone's unnecessary tasks down and such is to manually end tasks and keep a note which tasks are always popping back up. Once I've determined those processes/services, I would generally put them on the ignore list and have a widget placed on my homescreen so I may tap on it whenever I get a chance, or pass by it, killing off the tasks that I know don't make a difference on my daily use of the phone.
My ignore list consists of:
My Account
3G Watchdog
Voice Dialer
Beautiful Widgets
Widgetlocker
eBuddy
News Weather
BatteryTime
Astrid Tasks
Clock
MixZing
Google Voice
Gmail
Photobucket -- Because it doesn't give up after you've killed it.

You're going to take a battery hit overclocking. Other than that I'd look at what's running at any given time, and everything that you've got installed. There really isn't a need for a task killer. And if you're adept enough to use a module, you might want to look into disabling applications that you don't use via adb; if you haven't already.
To put it another way the more you're running, the faster your battery's going to drain.

Im Oc'ed to 1.4GHz and running all kinds of widgets and i text and call all day.
No issues at all. Both my orig phone and now my replacement phone.

So I'd have to check under running services under applications ? I uninstalled the task killer.
Sent from my HTC Vision G2

I am overclocked at 1.5ghz and my phone last all day. I think the two main things that attribute to this are:
1. I have a profile on SetCpu that underclocks my phone to 245mhz when the screen is off
2. I used this guide http://forum.xda-developers.com/showthread.php?t=809231 to disable alot of the stock apps that load automatically on the phone (Finance, Qik, Photobucket, Amazon Mp3 etc)
If you do want to try out the 2nd option send me a PM. I'm not sure if you are familiar with the application "Gscript" but it allows you to input a script and have it activate at the touch of a button instead of inputting lines in "Terminal Emulator". Basically, one click and all the BS apps are gone. Do you have the VISIONary root?

Yeah I do. Just charged my phone and it dropped from 97% to 77% in like a half hour. Something is def up. NOT NORMAL. And this was stock. No OC.
Anyone have a list of all the bloatware so I can disable them via terminal. Don't feel like looking thru pm list packages. Lol. Yes, call me lazy.
On a side note just looked at the temp of the battery its saying 101 f. Wtf?!
Sent from my HTC Vision G2

I just got the G2 yesterday to try out.
I charged the phone to 100% today and put it into Airplane mode (my office doesn't get reception), quit all the apps using ATK (froyo version), and killed potential network-hogging apps in Running Services menu. My battery went down to 83% without being touched in a matter of 30-60 minutes.
There's no custom OS/root/overclocking being done here. Anyone else find this a bit strange? Neither my Nexus One or Vibrant deplete this quickly. I also understand the whole battery calibration, but damn!

This seemed to help me. Try pulling out the battery from the phone for 1 min then pop it back in and power up. For some reason that helped. Phones at 50% with heavy use and I took it off the charger at 530am and its now 3pm

I too use Juice Defender and although at start is said 1.31...it now is going to 1.10. How do you all get such high battery life? I get at most from (what I call heavy use, twitter gtalk, txt, web, games) about a single work day which is 8 to 9 hours. Ideas...?

Battery life is horrible..just horrible

after getting 2.1 update..my phones battery life has become more horrible.
when i am out clubbing, phone doesnt even last 8 hours.
most friends with Blackberries keep their 3G switched on always so they can use whatsapp or BBM
but for me..if i keep 3G on..the battery wont last for few hours..
how are you guys dealing with this problem?
i am thinkin of buying an extra battery and keeping it in my pocket when out.
or thinkin of upgrading to some other android phone with froyo

My phone is lasting 2 days now.. I did find a few things that were killing my battery though (Handscent bug on unread text messages, some self updating widgets I was using.. ).. suggest you try to suss out what's preventing the phone from sleeping and ditch the app, or replace with one that doesn't cause the problems...
(I've also rooted, enabled JIT, removed Timescape and a few of the other std apps too but don't really think that any of that made much difference to my battery)

Using custom rom (2.1 b005 ; i know old, but good ) with a task killer and extended controls (app) for de-/activating APNs
Also using setcpu set to poversave, max 512 and min the lowest
Loosing 1% battery in ~3-4 hours

1% in 3-4 hours ..u mean standby time?
standby time is pretty decent by default anyway
but usage time is very very low.

Disable face recognition service. I get ~3-4 days of light usage now and can do a full day at heavy usage no problem.

i'm losing 3% an hour on standby and i have nothing running, how do you guys last 1-2 days?

that looks like you have such a lot of battery draining apps.
do this:
charge the phone all the night and in the morning turn it off.
instead of turning it on with the power button, press the MENU button and the power button both at the same time.
after you see the sony ericcson logo release the power button, keep the MENU button pressed until the phone boots up
now you are in safe mode
in this mode all your start-up apps won't boot, only the needed by the system.
Keep this way all day long and by the night check your battery indicator, if it is way too much diferent than before, blame your apps.
Also remove timescape, this will give you around 15% more of battery life.
btw: make a shorcut on the homescree of your whatsapp and everything you need to stay communicated, because they won't be on the apps drawer

Custom b006 is also great at battery life. I have 3g always enabled and connect a lot to wifi at home and my battery is at about 60% after a full day of usage.
Another tip, if you want to stick with original firmware, you could try data on demand. This enables mobile data connection only when screen is on and saves you a lot of battery.

Battery life has been greatly improved in 2.1 so I would be checking what apps you've installed because it's more than likely due to one.

If you don't use/configure Timescape, it doesn't take battery life. No need to uninstall. I haven't, and I can get two days, with plenty of usage.
I've found, though, if you reboot the phone after giving it a full charge, it tends to work a lot better. Yesterday, after using the phone for a few hours at/after work, I was at 70%. Played Angry Birds for 30 minutes, brought it down to 60%, and it was 56% by bed time.

I don't know how you guys are getting 2 days or more... for me, I'm struggling to get through the 24 hour period !!
Between, I don't like to turn off the data or stop syncing this and that sort of things. Stopping these to save on the battery, must get a old Nokia phone which can last a week without a charge.
Give any real advice other than this if possible.

Did u check whether ur battery usage have high "cell standby" consumption? I know mine has bloody high 40%...believe this is one of the culprit...
Compared with wife's x10 mini...hers superb battery life easily 3 days normal use..with 0% cell standby...argh..

I've said it before... Bad apps or bad widgets cause the battery to drain when on standby..
If you are getting substantial drain when your not using the phone then it's bad apps or bad widgets preventing your phone from sleeping.. when sleeping (even with wifi/ 2G/ 3G and syncing switched ON) you should be seeing between 1-3% per hour depending on how much you have syncing.
I've got FB syncing, auto sync on google sync (contacts, calendar), and googlemail push all on, all the time.
You need to work out what's at fault and find an alternative which doesn't cause the problems.

Also when you just updated your phone is doing all kind of stuff in the background. After a few days it is much better already, my phone last now for 2 days without any task killing application, but I did remove a lot of useless default crap using titanium backup application...

my x10 was stay for 2-2.5 days .
after using BB charger it stays 20 hours .
even when i back with the original charger it stays worse than before

I habe 3G always on and my Phone lasts 2-3 Days

Hmm without 3G / Data enabled I can use my phone for 3 to 5 days because I only use them when I needed it only. My friends have it enabled everytime and he gets about 1 days and a half in quite poor reception area, maybe other setting also affect battey life? because I think the x10 battery life is comparable to my previous nokia e52 with 1500 mAh battery in similar condition (3g / data and gps active only when needed).

Hello i'm a x10 owner and after the upgrade at 2.1 mi battery time is more than awful around 1,5 days on 1.6 i have the battery up to minimum 3 days, i use advanced tak killer on 1.6 i had es task killer (much better than advanced task) but on 2.1 if i select kill all it turnes of my signal and my sd card and if i select kill when scren off when i'm in a call and the scren goes of bye bye signal and convesation ( what to do??????????????????????????????

its not recommended to use a task killer on 2.1 as it has better task management
