My phone was 100% battery 4 hours ago - now it's 45%
I haven't even hardly used it this morning.
This is ridiculous. Any ideas ?

Maybe sounds silly, but do You have 3G / HSDPA full timeturned on and/or any data eating app(s) running in the background? Usually these drains my I9000 really fast. If I take care to turn stimes 3G off (only 2G allowed) and shutting down the app(s) which run in background make my phone usable for a day.
it's 100% normal to suck so much battery life if you are constantly using 3G or WiFi or long phone calls
I know how to disable HDSPA, but how to disable 3g? :S tnahks
You are using it or something in the background is using it.
Full-on use (gaming) burns about 20% per hour in my experience. Browsing might be a little less but not much because instead of using CPU/GPU power it uses data.
The screen is the major burn, how long does battery usage say the screen has been on?
My battery drain is always pretty much exactly 20%/hour screen time + 1%/hour on time. It will deviate from this if I've played alot of music (especially streaming) since it uses power but not the screen, this drain rate will depend on the player and type of music (built-in player playing from SD card is lean, Tune-in radio streaming over 3G is a hog that heats the phone up, Slacker is in between).

Could be a few reasons for that. If you've recently flashed a new firmware your battery stats may be messed up. Just run down your battery down a few times and it should sort itself out.
Maybe you turned your phone on while it was plugged in. This usually stuffs up the battery stats and can show as much as 30% extra battery when turned on that way. Always remove the charger before booting.
Also, to turn off 3g/hsdpa/data go to settings/wireless & network/network mode and select gsm only (2g). You can also download the widget '2g 3g' which will take you straight there. Also, you can uncheck 'use packet data'. This will kill all data which saves battery. I turn it back on with the widget whenever I need data again. The power button menu also has that option. I'm on 2.2.1 so it may differ if you are on 2.1.
Pretty sure you can still text with data off but may want to test it. If message fails then no. However mms send/receive won't work I think.

i can do 5 to 6 hours straight of 3G browsing with screen on auto before it runs dry
3G + Screen = high power eaters
if i play 3D MMO (pocket craft) then it even less time

I just recently upgraded to 2.2 froyo
i heard there's a battery stats trick, anyone know it ?
there's no battery stats trick . its just a logfile that's stored. nothing else. the trick you're probably talking about is calibration of the battery.
drain fully, charge to full while powered off. one or two charges like this should sort it.

Hey I have a bell i9000 and I have to say that I'm extremely happy with my battery life, I've been unplugged since 9 am, its 7:30 now and my battery indicator is reading 37% with above average use (some phone calls, gaming, browsing...) I would advise you to do these things:
1) install darky's rom (9.2)
2) flash speedmod kernel 13b (very good on the battery)
3) use setcpu and set with these values, max:800mhz, min:100mhz (conservative), and add a profile for screen off with min/max @ 100 mhz and 100 priority level (don't worry, your phone will still feel snappy even @ 800mhz)
4) use a black wallpaper, since black is rendered by turning off pixels on an amoled display.
You should see some improvements, hope it helps!

I read through quite a few of the battery issue threads but would still appreciate specifc advice on the issue I am having with mine.
I already couple times did the stats wipe as per the tweak guide on OT site but do not seem to have any benefit from doing it.
I am encountering the following issues:
Charging
Charging is very finiky. If i am charging in operation or while turned of the tab will seem to stop charging at certain levels of charge between 70% and 95%. If it happens while charging turned off I need to disconnect and reconnect in order to coninue charging, sometimes a few times.
If it happens when in operation similar will happen but also when the charge is reported at 100% I tun off the tab only to find out that the charge level reported by the off battery icon is not 100%. On different occasions it displlayed anywhere from 80 to 95% (estimated). Dont remember ever seeing it at 100%.
Discharging
If I turn on flight mode overnight I will get almost no discharge all night 0%-1% which seems very cool but my normal use is really wireless thethering. I just started not even 10 minutes ago from 100% charge and already at down to 90%. Just playing a game or browsing or reading the forum using the XDA app can completely discharge the battery in less than 2-3 hours. All of this in spite of the fact that I am on Jupiter, UC and UV heavily. I also manualy been stopping running services like skype and yahoo messenger.
I am afraid this could be a a battery hardware issue but would appreciate a confirmation or a suggestion of what else I can try before restocking and going to the service center to get the battery replaced.
Maybe you could advise which system apps I can freeze with Titanium and still be able to maintain wireless tethering and phone functions. Maybe an advice on a task killer and what I can and can't kill to keep the mentioned functionality.
While writing this post I lost 8% charge!!!
Dont get any task killers they kill system process then the system has restart them which kill battery. Have you tried wiping batterystat.bin when below 10% and charging to 100% while powered off.

The only way I would install a task killer would be if I could get someone to tell me which tasks to ignore so I wouldnt get this issue. No have not tried the below 10% wipe but will do so since you mentioned it. In the Kratos thread somebody mentioned to let it completely discharge and then without connecting to boot into CWM and let it further discharge. Aparently a system full discharge is not a full discharge and there is another couple hours juice left in the battery to keep the CWM going. Would this be a good idea?
Thanks to the helpers and to all you readers I think I found the issue. It seems to be a hardware problem but not with the Tab. The problem was with the charger.
I accidentally came across a car charger, bought it, used it to partially top up a couple times in the car and right away the Tab seemed a bit different. So I went back and bought a mains charger plugged it in last night and for the first time in quite a while it charged to 100% and it happened within expected time. Put it on charge at 1.30am and it was at 100% at 5.30am when I woke up.
Dont think it will effect the drain much but it is definitely giving me more juice to start with.
Oops!
Sent from my GT-P1000 using XDA Premium App
After running Kratos for quite a while with my new chargers and recalibrating by the book I am getting the expected level of battery juice. The tab charges efficiently to100% every time.
Drain is still an issue for me though. If i set airplane mode overnight (8hours) it will loose 1% charge but 9%-10% without airplane mode. On standby and in use the drain is consistant and fast. Not even UC and agressive UV helps.
I did a lot of app freezing and it realy doesn't make a major difference. Normaly I have only 4 services running. Settings, Google Services, AnySoftKeyboard and Google Maps.
I don't think I had the same drain on Hermes even though i didnt UC, UV and had at least a dozen services running. Think my battery life was better while others were complaining about wifi reconnection issues. ASAP I will try going back to Hermes to either confirm the issue with Jupiter/Kratos or to just accept this as normal and shut up.

I finaly narrowed down the battery issue.
When on wi-fi i will get up to 3 days of battery life but only up to 16 hours on 3G.
It has been suggested to change the modem. I am curently on JPZ. My GT-P1000 was originaly purchased in Saudi and currently, until my next contract who knows where in the world, using it in Croatia.
A suggestion on the most battery efficient modem that works globaly would be appreciated.

FYI - Kratos Overcome ROM has(or had, there's a new one out today and it might fix this?) a bug with wifi where that if you leave the network and then reenter it without manually turning off then on the wifi, it will constantly reconnect(or something) and burn battery like mad.
For now I just flip the wifi off/on again when i connect to a new wifi since i didn't want to leave Overcome. Hopefully the new one fixes it.
---------- Post added at 07:05 AM ---------- Previous post was at 07:04 AM ----------
and by leave/reenter network, i mean physically walking outside the network range until it disconnects, not disconnect/reconnect through the tab settings.
It may only happen moving from one network to another (i go from home wifi to work wifi to home wifi each day).
Mate thanks for the reply but think you misunderstood. I dont have an issue with wifi. My issue is with 3G/mobile network over SIM card. That one burns the battery.

So to understand what you are saying explicitly.
At home I connect to WIFI -- XXZ.. Its already a remembered network. I drive away from home and come to office here WIFI is YYZ (Already remembered network). So it automatically connects. THIS CAUSES the batt drain????
If yes, I am extremely happy. Coz I dont turn off WIFI it connects at home n office automatically. Please corroborate!

> I finaly narrowed down the battery issue. When on wi-fi i will get up to 3 days of battery life but only up to 16 hours on 3G.
I think that is normal standard consumption. 3G is known battery hog and you cannot compare its runtime vs. wifi. Is 3G on all the time, or maybe you attempted to use interval disconnectors (ie. battery saver apps) like JuiceDefender, Green Power, the likes?
Thanks jtdc!
I move around the world a lot and rarely set up wifi so most of the time I am full time on 3G. I dont use any power saving tools like you mentioned. Insted I use Titanium to freeze any apps that unnecessarily show up in running services.
I only noticed the differwnce with wifi due to an exteded visit with a relative who has wifi in his house. It wont be long and I will again be full time on 3G and would realy like to extend the battery life by minimum 4 hours. Are you aware if there is a known difference in power consumption between different modems or if any of the tools you mentioned can deliver this kind of savings purely by managing the 3G operation?
Sent off the Blue Marble using GT-P1000 on Overcome 7, v4 via XDA App
if any difference of modems that would be minimal to negligible. what always comes as the factor is the strength of signal and of course the tab which always scans for it whenever you're on the move. what you experience is typical, and in best case good because 16 hours on 3G always on? your battery and tab must have been setup really well.
if you can bear with interval disconnector apps like i mentioned, it would increase your runtime. for instance you can have the app connect every 15 minutes to 3G then be online for at least a minute to have all your internet dependent apps sync (email, messages, news, etc) and have traffic threshold detection in case in a minute some transfer still ongoing, then maybe 2 minutes is long enough. then for the next 15 mins 3G is off, then it will repeat the cycle. in that manner there's quite a lot of power to be saved and will definitely extend your runtime.
if really no other choice, i suppose you need to buy an external battery solution, the likes of energizer xpal, so you won't have to worry about battery life.
Great, thanks, that solution is acceptable for apps that require data services. Can you recomend an app to use for setting it up.
I expect it would prevent me from using inbound calls via Skype but how would using such an app impact incoming sms service and voce calls? Would they come through and would voice call quality be impacted.
Sent off the Blue Marble using GT-P1000 on Overcome 7 v4 via XDA App
"Green Power" in android market does the job and its free, that takes care of data connections (wifi or 3G) and will not tinker with the GSM radio, therefore sms and voice calls are untouched. The other app "Juice Defender" you can customize even to turn off the GSM radio, even downlclock the cpu, etc. which will result more savings but is a paid app.
Let us know how that helped to increase your runtime
Please bare with me, I am a fairly novice xda user.
I purchased my Bionic at launch, and it has been working perfectly until about a week ago. I always run the phone on stock OS not rooted, automatic brightness, 4g turned off, no wifi/sync/bluetooth. I would generally get down to 20% of my battery from 7 am to midnight on these settings, which was fantastic.
Suddenly, I now lose 10% every 20 minutes. This is not an exaggeration, I have been testing it with Battery Spy. CPU Spy reports that my phone never goes into deep sleep and is always running at the lowest mhz setting when idle.
Under battery usage, Cell Standby is reporting 45%, then Phone Idle at 35%, then Screen at 15%. The remainder its split between K9 Mail and Handcent SMS.
I have uninstalled everything that I thought could be causing this... Facebook, Google+, etc. Apart from the stock bloatware and k9/Handcent, my phone is like new. The best I could do is a factory reset at this point...
I don't think it is a bad battery because the stock battery goes from 100% to 0 in less than an hour when it would last half a day beforehand. I am really at a loss.
One thing I do know is that the 3g and bars are almost always blue, which I think it means is transmitting data. Maybe this is the culprit?
Please pardon my ignorance with the whole issue. Any help would be very, very appreciated. The Bionic was the best phone I have ever owned up until this battery fiasco, and I would like to find out why this is happening.
Thank you.
EDIT: would just like to update, Battery Spy reads that my phone is running at 104° Fahrenheit. I do not know if this is normal, but this was after an hour since a cold boot. Sounds high to me but I'm not sure.

Sounds like you have some thing that is really using up some cpu cycles. One way to see what's going on is to install the app Android System Info from the market. It has a section called Tasks and it will let you look and see what part of the system is using how much cpu. I do not think you have to be rooted to use this, but I could be wrong. I did go to the market and look and saw no mention of needing to be rooted.
I know this will sound extreme, but I would definitely do it if this was happening to my phone: Factory Reset and start fresh.
Good luck.
Thank you for the advice. I installed it, and appear from the Android System Info app taking up 50% of my cpu, and Android System using 4%, everything else was listed at 0.

Well, that didn't help much. Oh well, I would definitely do the Factory Reset then. Again that's just the way I would handle it as something is going on with your phone that wasn't happening earlier. Just go to the Privacy settings and make sure you have Backup and Automatic Restore checked. If your launcher has a backup feature, go to preferences and do a backup of the launcher settings. Then do the Factory Reset. It's a pain to have to setup everything again, but a reset really does cure a lot of ills that pop up.
Good luck.
Oh BTW, here's some general Battery saving suggestions:
Battery Life – BY: NoBloatware on DF
consider doing a factory reset. Do not sync apps, wifi connections, etc. with Google services as that may cause a problem. Install all apps and wifi connections from scratch. A bit of a pain, but not too bad.- install a home/launcher replacement. I use Go Launcher EX, which is free, and I love it. No reason not to try out an alternative launcher as you can always go back to how you had it.
- don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can.
- don't use antivirus
- the DLNA app pops up a dialog box that will set your WIFI sleep policy to never. The default is "turn off when screen turns off" and I personally think that this setting is the best thing for battery life. Under wifi settings view your connections then hit menu to see "Advanced options" where you can set the sleep policy
- if you have access to wifi, leave it toggled on as it is more efficient than 3G. This is different from the sleep policy.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- when you get a new battery, do a factory reset, or an OS upgrade run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will callibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- set screen brightness to "Automatic"
- under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- if you never use bluetooth then toggle it off. If you do use it sometimes, it's fine to leave it toggled on all the time.
- consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
- turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you're done using the phone. I use an app to lock the screen so I don't wear out my power button...as happened on my original droid.
- turn off in-pocket detection
- keyboard: turn off vibrate on keypress and sounds for any keyboards you use
- use a red screen background. On the original Droid screen--not sure about this Droid 3 screen--red was the most efficient color that could be displayed. Anyone know if this still holds true?
- camera app: i like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- in stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone.

Format the sd card in ur pc. Then put sd card back in bionic and transfer ur stuff back on it. Ur bionic is scanning sd card non stop for errors drainin battery. I had this problem for weeks beofre i figured this out. Was gettin 7-8 hrs on ext battery. Now ibget 30 hrs

I had a similar issue and the problem was my sim card needing to be reinstalled. It was not seaded correctly and caused my radio to act up. I truned off the phone and removed the sim card and then reinserted it and rebooted and I was back to normal.
I am not sure if this is your problem but it is easy enough to try.
Would this apply if I am not using 4g? I have 4g disabled and it was my impression that the sim card was only used for 4g.
I uninstalled k9 which for some reason began using 7% of my battery though I had never opened it since reboot and now I am getting a loss of 10% per hour of normal use.
I went to bed with the battery at 70 and woke up with it at the same so I at least solved the sleeping problem. Not sure why k9 was responsible though.

Hi all,
I've been working on getting my XT862 to give me more life on the battery. I've rooted and debloated using psousa's stuff, but I'm still not where I'd like to be. I've noticed a few interesting things:
AOS is showing as the top user in the battery monitor. Currently it's at 32% with my display and WiFi bringing up the rear.
Even though I've run the debloat script as root and confirmed the rename of skype.bourbon and motoprint, these things still start up. How is this possible?
BetterBatteryStats shows that the suspend process is my main battery user. How does one fix that?
Any advice on what to look for?
best route is to install a custom ROM and try different ones out for battery life. I would suggest Maverick ROM also make sure you wipe battery stats after installing a new ROM and fully cycle your battery.

I'm guessing suspend is another way of saying System Idle.. if you wanted to get rid of that, make a nandroid backup of your system (via bootstrap or safestrap) and experiment what system apps/services you can freeze (via Titanium Backup) without getting force closes on the stuff that you use. I have about 30-60 system apps/services frozen depending on the ROM that I run. I have no force close issues, and my system idle uses about 1 percent of the battery per hour.
Additionaly, if you are using the CDMA network, force CDMA mode, likewise from GSM/UMTS, if you are using it, force it, do not use Global, as it will have both radios running and searching for service.
Disable the use of wifi when you aren't using it (there is an option to auto turn it off when the screen turns off, however this may cause worse battery life if you are using data as it will try use your mobile network, requiring more power), if you wish to leave it on, increase the scan time interval (i made mine 10 mins, up from the stock 45 seconds)
Auto brightness (it isn't really that bad...)
And get the app called juice defender. Once you set it up it controls all of your wireless stuff. Like turning wifi and 3g off when you turn your screen off, etc.

If you use Wifi often, it is a good idea to check your Wifi Sleep Policy. To do this, navigate to:
Settings > Wireless & Networks > Wifi Settings > Advanced Settings (hit menu to access this) > Wifi Sleep Policy
I have mine set to 'Never'. By default, it was set to turn off the wifi when the screen went off, so any background apps that run and use data default back to the mobile connection. When you turn the phone back on, it turns the Wifi back on from sleep mode. By changing the sleep policy to 'never' you prevent this disconnect/reconnect to Wifi cycle.
This helped my battery life when connected to Wifi. Let me know if it works for you.
Thanks to all
Thank you for your replies everyone. I'll have to get TB and start freezing stuff. What confuses me though is how a service like Verizon Apps or Skype Mobile gets started even though it was renamed ".bak" by psousa's script. Also, I've noticed that when I run the restore bloat software, I don't get back all the apps in my app drawer. I'm not sure why that is.
Is it possible something got screwed up if I ran the debloat script twice? I see that it does a bunch of mv proggie.apk proggie.apk.bak type work. If the first file wasn't found, is it possible that it overwrote the .bak with gibberish?
My WiFi sleep policy is never because I have WiFi all day and I like Google Talk a lot. I'd be happy if I could get WiFi/Display as my top users, just AOS seems like a bug.
I'm on UTMS so it's forced to that all the time.
Maybe the answer is to try the mods. Or maybe SBF to the stock and try again?
Hi, need some help,
I got this phone a couple of days back, its an unlocked one. Battery on the phone seems to be draining faster than i expected it to. The first time i charged it, it took 3 hours in the afternoon. By night it was 20% this was after playing games and downloading through wifi, so it seemed ok. I then put it for charge overnight. The next day it still seemed to drained by 7pm only used whats app this day, so i had to put for charge again.
Once fully charged (2 hrs) I shut off wifi, bluetooth, nfc and others. Switched off smart stay options and the display is set to lowest brightness (not auto). The wallpapers is also black so it will not drain battery. Overnight without the phone being used (only thing i set was alarm) the charge went from 89% to 78%. During the day I also find the charge still dropping pretty rapidly. I have included the screen shot of the battery from the same day. Between the first pictures there is no difference in use and still drops by 3% in 20 mins or so.
Is this a problem with the battery or is that how it is?
(Stock, no changes to rom)
Not sure if this is your specific problem - but one thing I've found that kills this phone fast is bad 4G cell reception. By default the phone runs as LTE/GSM/WCDMA (Auto) in Settings->Mobile Networks . If you are in a location with patchy (or none at all) 4G Coverage, the phone wastes an inordinate amount of juice switching to high-power mode on the cell radio searching for the elusive 4G/LTE ... Just like a 3G phone will deplete its battery extremly fast in a location with no/poor 3G connectivity (inside the 'secure' datacentres I wander into occasionally that have cell blockers, I can deplete the battery in a phone in about 3 hours just due to it constantly switching to high-power 'cell search' mode as it has no details on any cells to 'hand off' to....)
The difference is palpable... inside my office, if I have the phone on the right side of my desk closest to some windows, it will receive 'patchy' 4G and I'll go through about 60% battery over about 8-10 hours with intermittent phone use (most of the battery goes to screen time as I'm a 'fiddler' whenever I leave my desk for a coffee/break/etc...) If I place it on the left side of my desk, where the reception is much worse, it'll fall back to 3G and I'll go through about 80% battery doing nothing different...
I'm now in the habit of switching the phone to WCDMA Only when I'm going to be working in the bowels of the building, as there aint no hope of 4G there...Doing this drastically improves battery life.. Likewise if I'm stuck at home over the weekend, I leave it on WCDMA, as where I live has very patchy 4G as well and I only get it if I walk outside and down the street...
Just a possible reason for the excessive drain... at least worth trying anyway... *shrug*

Hi thanks for the reply. My phone does not show WCDMA in settings. It just has 2g/3g/4g/ auto OR 3g in network modes under mobile networks.

I have used an app called "Radio Switcher" to activate "gsm auto (prl)", when i open the app it seems to go into "Device info". It seems to work but "Network mode" does not seem to change.
I have uploaded the screenshots
Seems as though the system is using more battery than the screen itself.
The system seems to really take up way too much battery power. Mine is at 4%.
What are your sync settings? Especially for things like Weather, stocks, news etc. If you set them to sync every hour or so, your phone will keep running on the 3G network which will end up draining your battery.
Also, switch off motion. It's a cool feature, but it's not necessary. Same with auto-rotate.
Finally, use WiFi instead of 3G where possible. That saves battery too.
If you're rooted, download noFrills CPU control and reduce your max clock frequency on days where you won't get a charge. Phone runs well enough on 800mhz, but has a tendency to keep going at 1.4Ghz for no reason.
Otherwise, get a higher capacity battery

My sync is off, plus i have disabled sync for everything individuality and disabled all unwanted apps. Data service is also off, only use wi-fi. under motion only smart call is on and auto rotate us off.
I have uploaded a screen shot off after ti disable all these apps.(went to bed with 35% and was 28% in the mornin, turned wifi off before)
Will upgrading (official) phone to android 4.1.2 help (current ver is 4.1.1)? Current base band version is i9305BVALI5 i got an update on kies to i9305BVALI3. I don't think this is update to 4.1.2 is it?
I have updated to 4.1.2, and applied only gsm setting in mobile network. All apps are still disabled as before. The system still seems to be suing most amount of battery, more than the screen. I do not know what is using the system.
I have stared having the same problem a couple of days ago. Though I have sync enabled 0-24 for 3 gmail accounts, motions are on, screen auto rotate is also on. I am using nova launcher, almost all Samsung apps are frozen and most of time I am on wifi.
Now, this drain has nothing to do with the stuff I just mentioned (Enabled sync, motions...). I have all that things enabled all the time, and yes MPU and GPU are OC to 1600 and 640 MHz. But I was always getting >= 24h with ~3,5 h of screen on time. As I already mentioned, problem started a couple of days ago. Only thing which comes to my mind is that I have played with freezing / defrosting apps and I probably installed a couple of apps too. Like Beautiful Widgets and that's my main candidate to blame for this at the moment.
Though I am still not sure... Better than battery stats didn't show anything what could help. Network location locator or similar is at the top of the list of partial wake locks. But the time it hold the lock (About 25 min.) can't be the reason for such a high drain.
I have switched to HD Widgets, what I was using before (With this app one can disable auto location.) removed Beautiful Widgets, and turned off'Use wireless networks' and GPS in location services hoping it will help... So we'll see...
For me it still shows that adroid system and cell standby time is using a lot battery.
I don't get why android system and OS is using so much battery, everything is disabled. Network is on only GSM setting and i have network all the time, why is that also high? Does someone else also have the same problem?
If possible, install Better Battery Stats, maybe it will help you to identify the problem... In my case it is not of much use at the moment.

Strange idea: download an anti-virus and let it run.
Might as well give it a shot now, especially since AV is free.

I was using AVG, but i removed it thinking it could drain battery.

I think he meant that it could be a virus that drains all the battery.

I did an upgrade using odin to 4.1.2, the issue still remains though. The screen shots i posted is with the update.
So any virus should also be wiped out right?

I have installed better battery stats, and it says that battery drain is 6% an hour at idle. I have attached the screen shots. I do not have root access to access some of its functions though.
