Ok, just flashed to CM 7 #22. My battery usage indicates 35% for android system.
My settings were the same on RC 2 and usage of android system was like 5%?
what exactly is wrong?
I have sync apps all day long on RC 2 too.
more info is needed. you need to post your total battery percent that you started with, and how much battery dropped, and how many hours that took to drop. and also post your "screen on" time. without that info, your android system 35% is meaningless. maybe the phone was only unplugged for 25 seconds, and android system used 35% in those 25 seconds. we need the relative usage.

im sorry, . I just wiped battery stats so dont really have a screenshot of it.
but essentially i started with 65% battery at 6pm, ended with 32% at 10pm, with no major usage (no games, minor web surfing, accounts syncing were on) , display usage was tabulated to be 50% and android system 35%.

That info was before i wiped battery stats. I recalibrated my battery and will post an update in about 10hrs time.
Roughly 3 hours into battery time, with minor browsing. Android system is using 30%.

Seems pretty normal to me. How much battery have you lost.
I have a N1 in 2.3.3 and had the same problem. Right after I updated from 2.2.1 to 2.3.3 android system would devour my battery very quickly. Turned out to be an issue with how gingerbread handles wifi sleep. I changed wifi sleep policy to Never and the android system usage of my battery decreased slightly. Then I took it a step further and started turning off my wifi once I left home (constant wifi source). Since then my battery life has been amazing.
Again I'm on a N1 not a NS but maybe it'll help.

I agree with this as well.. Infact, i'll go one step further and say leave ur wifi off, if your phone finds it hard keeping the connection..
I assumed that leaving my Wifi on would be a good thing while I was at home..but certains parts of my house have pretty lousy wifi coverage... so i switched wifi off completely..and tadaaa.. my battery lasted a lot longer..
(i guess its probably because my phone had to spend lesser energy "searching for wifi" and then hooking onto poor reception, only to lose it again in 5 minutes.)
have a look at the inflection in the battery usage graph attached at the point where i switched wifi off ..definitely looks like something's up with wifi
Try CM7 build #26. The battery life is quite impressive on it, especially when on standby mode. Over night, it drained the battery less than 2%.
i'm having an issue with this as well.
running stock rooted rom
11hrs 49 m on battery
display 29% screen on 2h 12m
android system is 17%
etc.
why is android system so high!? i don't recall it ever doing this before until recently.
@crzdcole
If your overall battery life is still ok, then nothing to worry about. High percentages in one part doesn't automatically mean something is wrong, might as well be that the other parts - in relation - just take less.

Did you do a full wipe before flashing?
Try a full wipe and reflash - only with little market apps installed
i did a full wipe with the tool you gave in your site

That's defintiv much too much.
Look at battery stats in settings - phone-info - batterty - drain (or something similar) if any market app drains your battery.
Did you restore system(!)settings with titanium?
Last exit: wipe everything (eg from recovery - I'm not lbc,so it's not my tool ), redownload (md5 sum!?), reflash - and do not install any market apps for the first hours. Battery drain should be max 1% per hour with screen off.

Did you perform the battery re-calibration that is recommended after new ROM install?
see LBC post http://forum.xda-developers.com/showpost.php?p=14981516&postcount=581 where he corrected the previously written method.
I'd recommend following these instructions and then check battery usage again.
This thread should not have been started here in Development section, but either as post in LBC ROM thread or as new thread in general.

I never ever did such a re-calibration, but perhaps it helps...
Normaly battery indicator is correct after at last 2 days of normal usage (I always plug in over night and never turn off the phone - so seems that it re-calibrates itself)

I had the same problem with lbc 0.5.2. The battery life was like 12 hours normal use.
So i went back to lbc 0.5.1 and everything works fine. Standby time now more then 36 hours.
Maybe this will help you for a while.

Sorry to repeat, but did you try battery re calibration yourself and not the version described on post one of LBC thread but the new and corrected version where you reset battery stats using app at 100 mentioned in post #581

Hey, sorry that I don't wrote that I tried this too.
I wrote with LBC about it. He told me, that he dont has the problem.
I also thought, that maybe the value isnt right, so I dont recharged it, but at 1 percent the phone turned off.
With 0.5.1 I dont have any problems.
mine drains fast as well...
I have followed all the instructions for a newbie with android in terms of saving battery life, but I still feel that my battery drains fast than the normal. Here is the scenario...
Full charge @ around 10-11pm, with one hour extended charging.
Turn off wi-fi before sleeping @ 11:30pm.
In the morning, battery is at 99% capacity as per battery indicator. Screen is at 25% brightness.
Turn on mobile network connection upon arriving at work @ 7am, there's no wi-fi in the office.
At about 9-10am, battery indicator is at 52% capacity. I normally use my phone in browsing Facebook, playing a li'l poker before working (my office is secluded), some browsing etc. I don't watch videos on my phone.
At around 12noon to 1pm, I connect my phone to USB charging in my PC, battery is at 25% only.
I don't think this is normal. My best guess is that the network connection is draining my battery, but I have no other choice but to use it. I'm need it turned on while in office to be connected to the outside world...
Anyway to extend battery life???

Does this mean you are connecting to data through the mobile network?
Is your wifi connection still switched on as well?
If wifi is searching for a connection all the time this will seriously drain the battery.

Depends on their sync settings. The battery stats app will show you which is the greatest consumer. If it happens to be facebook, dial back the usage. I used IM+ briefly, but uninstalled it. I can't remember why. I'm not on facebook.

I do the calibration after any flashing of custom rom. And it's allways helps to me, battery live is 2-3 days after this, and 1 day or few hours if not calibrated after flashig new rom.
Android 2.3.5 roms drain battery mush lower, and work faster. Flash it and calibrate battery after.
Hi, I have just come over from the HD2 threads as I'm using a Sensation XE now . My battery current when running android on standby was around 7 - 20 ma. On my XE it is between 180 and 220ma. I killed all running tasks etc but still no change. i'm using Battery Monitor Widget to check the currents. The only thing i have on is mobile internet. I also have on background sync but that was on with my HD2 as well. Is there anything I should look out for that my being draining the battery? Also I'm on stock rom
What did you already tried to solve the problem? Did you already do a soft reset/wipe all data (except that on the SD card)? How long is your battery life?
Yesterday i called HTC because my battery life is reduced drastically compared to a few weeks ago. They told me to turn off everything like bluetooth, wifi etc (after a soft reset) and put the phone in plane mode while screen brightness was 100% and screen time out never so the screen stays on during the test. Next I needed to write down how fast the battery was drained. My battery was at 55% after 2 hours (without doing anything with the phone). According to HTC this was to fast and therefore they send me a new battery.

In 1 hour of standby the battery has drained 5%. the battery current usage is way to high for standby. I have had this phone on 3 days so I dont think i need to do a full wipe. I dont use wifi or bluetooth and they are always switched off. Seems strange to have a high battery usage while in standby compared to my hd2. This battery is meant to be a high capicity
use battery monitor widget (use a beta version from the forum, not the market). set it to "mA corrections" and choose automatic from the list of supported phones. i get anywhere from 5-7 mA drain (standby, of course).

Hi, I'm on stock Rom too. Once I kill all tasks by the default task manager, it ranges between 25 - 60. It does take a bit of time to get there. I Have seen it as low as 19. You need to follow steps and get the beta widget and set it to corrections as mentioned earlier in the posts.

Just a quick update. I let my battery completely die (never done this before) and charged my phone fully. I then deleted the battery stats.txt and switched phone off. the charged some more. Now when my phone uses -5 on standby which it never did before.
Well took my phone off charge at 11.05 today and its been on standby. It's now 15.52 and battery is still on F. Battery drain is now at -3 so i'm well happy.
Thanks indie. Can you let us know what will be happening in the future with your battery?
I know this phone is known for having battery issues, but I wanted to know if my situation was normal.
70% in 10 hours of no use, sleeping overnight
Is this normal, or am I doing something wrong?
Running Rubix 5.3 with a 192/192 governor when the screen is off
wifi is always on, even with screen off.
fancy widget updates location and weather via gps and wifi every 15 mins
brightness 100%
NO mobile data active (should save battery, no?)
[/LIST]
those are the most battery consuming things I can list about my phone
I do not charge my phone overnight as it's bad for your battery. But I have noticed a crazy battery drain even when I'm not using the phone.
After sleeping for 10 hours, my battery dropped from 100% down to 30%
This is the first out of FOUR different android phones I have owned that has appalling battery life. My G2 under the same setup would give me 20+ hours on a charge, with some moderate use

battery drain soo fast when in use
i bought my samsung galaxy 2 tab 7 p3100 few day back and im not satisfied with the battery when in use it battery drains soo fast approximately stands for 15 hours only when left unused stands for 1 and half to 2 day...i can see battery percent goes 1 by 1 with minutes when i use is continuously and my version is P3100DDLE1 ... i use 2g gprs all the time and stay connect all the time in facebook and whatsapp 24x7 and gmail ....... should i claim warranty for the battery??? does anyone face the same problem????
I am running on roughly 7 hours at 78% of battery left. Been using the Internet a lot (Facebook, some Drop Box upload/download) and the Wifi is on all the time when the tab is not locked/standby. I played a little bit of a basic game as well (Free Flow), so it isn't graphically intense. I am by no means the most experienced here, but in my opinion, that sounds like some decent, if not very good, battery usage..

Yes, my screen is usually on about 6 to 7 hrs. And my battery life is about 15 to 24 hours.
I wonder those said their battery can stay for more than 1 day, how long was their screen on?
My guess is although the battery can stay long time but the screen on is only about 6 to 7 hours.
If yours only 5 hours maybe the gsm signal was not good. Try to change to 2g only. Or change other provider.
Hey thanks for the reply i use 2g sim only and I'm 24x7 online in 2g gprs i guess the gprs can also consume that much battery I guess I'm i right????

I am sure there are people who use the tabs for different things,if you are studying or reading a lot you will be able to see how long it lasts on, for users like me that turn it on and off pretty often the battery lasts maybe longer. I use it a lot for hours and hours,but it is never on for more than 1hr.

No problem for me about battery on Tab p3100
I felt that having Sim card inside the 3100 drains the battery pretty fast. I was not using much of 3G/GPRS connection. So after removing the Sim, I found battery usage reduced drastically. Overnight, the battery used to drain by 7 to 8% in standby mode with Sim card inside.
I don't understand, how people can comfortable use tablet with screen brightness at 0% or even 20%... it's mystical to me..If you buying tablet, you want to get good screen quality, good battery life (even at 50-70% brightness), smooth performance and so on...I have 2 tablets, ipad 2 and Samsung 3110. I really love my samsung, but battery life totally suck on it, when you compared to ipad...
Not a good comparison, iPad has a bigger battery
