***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.
Samerhing happens to me... and I just took it off the charger and I'm on 96 percent in less than 1 min

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

Spare Parts says "Time spent without sleeping: 53m 15s (100%)
Wow.
If I go to Battery History and change the top dropdown to Partial Wake Usage, it says Android System at the top with a bar that's at least 75% full.

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

try disabling gps in the notifications, that worked for me, but once i turn gps on again, it will drive up to a high percentage.
I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

maybe try out BetterBatteryStats, duuno but maybe this could help?!
cheers and good luck!
Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

speedmod is a kernel like siyah rite? i've use siyah before, but it doesn't seem like much help. nonetheless, will try them ^^
thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
Hey,
I could not find a thread like this via the search bar, so I am opening one up. How much battery does your stock S3 consume by just lying there? I am losing about ten percent overnight, which seems a bit too much for me. Is that normal?
Thanks!
Wait till you get about 70 percent discharge overnight then you'll have something to worry about.

If you searched or read the multiple battery threads then you would have found that yes it is normal .
All depends upon what running .

At night I turn off wifi and data, my battery drops 3%, with data on and wifi off about 5% ( about 8 hours)
Based on reviews on the net it is possible to get it drop 6% in 16 hours with data and wifi on, not getting to this myself but happy enough.

It is very normal for Stock rom to consume that much battery.. However you can save more battery by going into Wifi > advanced > Keepy wifi on during sleep > Select Only when plugged in... Plus disabling wake up commands such as the ones for S Voice, or Google Now can increase battery life upto a great extent.
Also try turning off location services for apps that you don't use that often or the ones that don't really require location services that much.
I had 10 to 15% drop the night, after installing Chrome (because of google sync issue)
but after removed it.. im back to 6-7%
Anyway Dolphin is better
I can only say from memory ...

I can only say from memory - a very clean S3 should get at most 2-3% discharge overnight (even with WiFi, data, BT and GPS started). That might no longer be achievable once you have a number of programs that interact and keep the CPU from staying into deep sleep.
Currently I am seeing at most 1-2% with my configuration - but that involves closing the 4 above before going to bed.(and to get to that point I had to drop a number of programs that were bad in this regard).
Do your own tests with that - look around after BetterBatteryStats.apk or something like that!

Can I ask what your current configuration is?
I am currently running Omega v32.1 with the stock kernel.
I hardly use my phone during the day as I am at work for 12 hours, maybe send a few texts. 3g and sync are always on
I take it off charge at 5.30AM and when I get home at like 8PM it is down to less than 10%... and thats not even heavy use.
I have calibrated the battery using that batterycalibrate app for root users..
Hello,
I wanted to get your guys opinion as I believe my phone may have turned defective and I really don't want to go down the Warranty Route as I'll loose the phone for weeks. And willing to try anything suggested.
So here's the problem:
Battery Draining at very high rates. On stock battery, I am draining about 12% an hour, after 6 or so hours my 15% battery capacity left warning turns on. I figured it was the battery, so bought a double capacity 4200mAh Hyperion Battery. Now my battery drain is at 6% an hour (which is equivalent to the factory battery considering the double capacity).
I am currently on XXELKC 4.1.2 Stock ROM. When I first noticed the problem, I was on 4.1.1. Figured I would ODIN, Wipe all cache's, and start clean. This has made no affect on battery life.
Here's what I've tried:
- 4.1.1, 4.1.2 Stock ROMs from Wipe - High Drain
- Airplane Mode with Location Services Disabled - High Drain, but 4.5% an Hour instead of 6% an Hour.
- Disabled all Samsung Apps - seemed to have little impact
- Disabling Google Now has made zero impact on battery life.
- 4.1.1 BBS revealed nothing - may need to try again on 4.1.2
Any ideas? Or is this sounding like the phone? Is it possible after a wipe the phone, when I re-enter my Google Credentials it is restoring some data which is defunct and causing high drain?
Note: Screen shots are with the double capacity battery taken right after a clean Odin upgrade to 4.1.2. Only ran Android Activation and thats it.
It looks like your phone isnt going to sleep properly. Try a custom rom/kernel.
Have you done a full whipe ?? If not, do so, and don't forget to make a back up first. It worked for me !

I had similar issues, I factory reset worked, and I also download rescan media root app to disable the media scanner which was my main battery killer.
WHen you do the factory reset make sure your phone is connected to the internet, so it will prompt google to store the apps you have and remote install when you sign back into the phone.
I have performed a full wipe but that had minor impact on battery life but I wounder if the Google Restore possibly restored an invalid setting. I will try this again without entering my credentials and see if there is a link with a restored setting. I will have to give the rescan media app a try as well.

Any specific kernel in mind. From what I've been reading no kernel seemed to stand up to magically solve battery issues without voltage drop or cutting services like Google now from the rom.
use better battery stats app to determine what is causing those wake locks.

I have attached a run with BBS for 1 hour. Nothing is really standing out. The phone was in deep sleep for all but 2 minutes. I did have Google Now and Location Services Disabled as that was eating away an impressive 10 minutes / hour from deep sleep. But my battery life only increased from 6% an hour to 4.5% an hour. An improvement but weak IMO considering the larger battery.
Results from BBS is attached.
I once had that kinda issue too
What I did was Factory Reset and that did the trick for me
How about trying the app CPU sleeper?

I've had this issue before on the i9100 Galaxy S II, where it didn't seem to matter what I did, it chewed battery just as soon as I put my Google account back onto the handset. I believed it was caused by the Samsung calendar bug. So absolutely; try it without putting your Google account onto the device.
Also, your WiFi signal looks low, although this has less of a difference compared to having low mobile coverage...

your first post has a huge amount of wakeocks that arent going to be reflected with an hours run on BBS. If i were you id charge it to 100%, unplug just before going to bed and then show us the BBS log in the morning so people can see whats happening over an 7-8 hour peroid

Hello,
I wanted to get your guys opinion as I believe my phone may have turned defective and I really don't want to go down the Warranty Route as I'll loose the phone for weeks. And willing to try anything suggested.

Have you tried flashing a custom ROM?

It looks like the same problem I was having. Your WIFI is always on.

Also leaving your Bluetooth On all the time is going to drain the battery pretty quickly.

its not wifi always on, my wifi is always on too and i lose 2% over an 8 hour standby period.
Its more what apps are using the wifi connection and waking the phone up, thats what the op needs to look into
I have to say ive had pretty bad battery lately aswell. If op doesnt mind I might post my bbs log tomorrow sometime
tapp'd on my S3

More information can't hurt. Post in and Maybee there is a correlation.
OK. So I went ahead with your suggestions and did the following
Factory Wipe again from Settings Menu
Went back to factory Samsung battery for consistency in reports to other users
Took out both my sim and sdcard to eliminate those possibilities
Put into airplane mode
Disabled a bunch of apps (ss on next post)
Still bismal results but better than before. 7 percent an hour drain. Attached all the files. Ideas? Google says phone is awake but bbs doesn't seem to shed any clues for me...
And here are the disabled and installed apps
your phone isnt going to sleep at all....something is keeping it awake..try a stock rom ( any will do) with full wipe. Dont restore anything with titanium backup. Disable auto sync on everything. Set wifi sleep policy to always. See if the problem persists.

That last run posted was stock 4.1.2 XXELKC firmware and Factory Wipe from Settings Menu. I also performed Wipe and Cache Wipe in the Bootloader (Power Up + Center + Power). All I did was install bbs and never put in Google or Samsung credentials and disabled some stock apps from running.
If your not referring to factory Wipe, can you please explain further? Thanks.
Hey guys.
It seems like almost everyone with battery drain issues has Android OS at the top of their battery stats.
I just want to share my experiences with this particular Bug.
Maybe it will help anyone. Please share if it also helped with your problem.
I had the Android OS bug since I dropped my phone a few months ago and had the screen replaced. The guy who replaced it (official Vodafone shop employee) said that they didn't just replace the screen and that something else was also damaged (they didn't say what) so they also replaced the rest. Well, that's when the Android OS problems started. I tried many ROMs and many Kernels. Sometimes the problem went away for an hour or so, but it always came back.
Then I finally decided to use BetterBatteryStats two days ago (I really should have done this earlier, I know...). I came to the conclusion that I had some sort of the well-known "fuel_alerted" bug, since fuel_alerted was the service that kept my phone from going into Deep Sleep.
This bug should have been fixed long ago but for me it somehow still persists, even on stock JB.
It didn't only drain a lot of battery (I had 8-10h maximum without doing much), it also used up a lot of CPU time, effectively slowing down the whole system to the point that I wasn't able to use Spotify on my phone without severe stuttering.
Well. I found a solution to the fuel_alerted bug.
The procedure is: turning airplane mode on, shutting phone off, taking out battery, putting it back in after a few minutes, turning phone back on.
This solved the problem. No more Android OS draining the power. Phone goes into Deep Sleep again. Only 2% drain after an hour. Spotify runs smoothly again. Yeah!
BUT well... It seems like the problem comes back randomly for me, today I had to replace the battery 5 times...
Now I am trying to strictly follow another "rule" to keep the problem from coming back: Always waking and unlocking the phone before plugging it in or out of power. I never did this before so it could have been the cause of the bug. Now let's see how long it stays bug-free.
If it still doesn't help, I guess I have to conclude it's some kind of hardware problem, which could only be solved by Samsung...
EDIT: Nope. Problem still there. So not really a fix, but maybe still helpful for somebody.
Okay, what ROM are you on?

It's the up-to-date stock Samsung ROM I guess. See attachment for infos.
Damn, it seems like the problem just came back without me doing much. I only checked BetterBatteryStats every 30 minutes or so and recieved 1 SMS just a minute ago. Seems like the bug started 20 minutes ago, when battery was around 78%. Now it's draining battery like hell again, Spotify stutters, Deep Sleep won't work...
Guess I'll have to pull the battery again.
Since I'm pretty new to all this: What kind of information would be useful to narrow down the source of the problem?
I can provide my BetterBatteryStats screenshots and logcat/dmesg files as well as my Android Battery Stats screenshots.
Is there anything else I could post?
Yeah, screen shots of partial and kernel wakelocks.

I just rebooted the phone, waited for a few minutes and took screenshots.
Here they are.
Okay, this is what you need to do now, drain it empty, charge it (while phone off) till 100 %. Remove the battery, wait for 90 sec or so, put it back and power on.
It's a placebo, but it might work.

Okay, I will try and do the charging overnight. Thanks!

I don't know much about kernel and ROM stuff, but I was just wondering...
As far as I understand, the fuel_alerted thing turns on if the battery charge goes below a certain threshold. The old bug with it was that, when recharging, the fuel_alerted thing would sometimes still stay on, even if battery charge is no longer critical.
Could it somehow be possible that this threshold is not set to 15% for me, but something around 80% due to some horrible bug?
This would explain why it suddenly turned on at around 80% when everything was fine before.
We're trying to adjust your fuel gauge and sort of calibrating your battery.
Sent from the little guy
Okay, I did exactly what you recommended.
Everything went well for about 2.5 hours.
Then the fuel_alerted process began again, but this time only for a short while apparently.
It took about 5 minutes kernel wakelock time in a 30 minutes measurement.
Way less than usual and when I check now, it's no longer active.
So. The problem might still be there, or it might not.
Do you recommend going through a few more recharge cycles to get the gauge set properly or do you think this won't make it better?
By the way, thanks for your quick responses!

Not really.
Now, when it gets to 15% or so plug it in (while phone ON), get battery calibration from play store.
Run the app, when it gets to 100 % hit calibrate. Plug off the device. Turn off.
Take out the battery for 90 sec again, reinsert it and power it on.
That calibration app is another placebo but as I said before, placebos sometimes work.
Sent from the little guy
Since the battery calibration app requires Root access, I flashed a Dorimanx kernel a few hours ago. Then I did a factory reset and the battery-removal thing. 5 hours have passed now without the bug, 3h of which were without wireless access (maybe it correlates with that).
I'll now let the battery (slowly) drain below 15% and then recharge it with phone on overnight. I will use the battery calibration tomorrow and will inform you about the results later.
Thanks man!
Good to know
Sent from the little guy
I did the battery calibration. Bug is still there, no changes
Post you battery details and a couple of BBS screens.
Sent from the little guy
Okay, here are some screenshots.
From the graph you can clearly see when the bug started.
Is it normal to have >26 kworker processes running?
Something else that concerns me: >2h without or with unknown signal. The whole day I was in an inner city area where the signal should be good...
Can you conclude anything from the screenshots?
I will now try something which I also should have tried earlier
I have a spare battery (not original samsung, less capacity) which I just put into the phone.
I'll let it fully charge with phone off and then I will try if the problem persists even with the other battery.
If it doesn't, the problem might come from the battery itself...
Is this a good idea?
No it's not.
You gotta post detailed info there, we can only guess what's draining your battery.

Okay... I posted the screenshots you asked for...
What more should I post?
