I have seen very conflicting reports about battery life when running Android. Some claim they have battery life as good as WinMo (1-2% drain/hr standby) and others claim anywhere from 5-8% drain in standby/hr.
I don't really think there is a difference between builds because I see claims of good and bad battery life for basically all builds.
To straighten this out I thought I would start a poll - please tell me what kind of standby drain/hr you are getting.

Need to add selection to see which build people are using also as well as battery life. That way we can have a better idea which build(s) offer best battery life.

I tried two Android ROMs a while ago - shubcraft (I think 1.2b) and Darkstone's Sense.
Shubcraft DEFINITELY had much lower consumption than darkstone's ROM, both in standby and in use.
It's just a shame the shubcraft ROM is so ugly.
With shub 1.3 and mattc's sense build I get less than 1% drain in standby. Shub 1.4 burned slightly over 1%. When I'm in standby everything is off except the phone radio. I also don't use any task killers.
Still not as good as winmo though. I only use 1% every 3 hours on standby in winmo.
Why do you consider shubcraft ugly? Because it doesn't have sense? I love the performance and look of the shubcraft cyanogen rom 1.4b. I get battery life very close to my WM energy rom.
I have a
TMOUS HD2 with 2.09 radio in NYC,
Chucky Android rom and Darkstone V2.1.
It drain >7%/hour for standby.
Can someone tell me how they get <1% per hour battery lose with which build, device and etc? I really like to try that out sometime.
Its a bit more then 1% per hour on shubcraft 1.4, but i use SetCpu.
shubcraft 1.4 @ 925mV r4 KERNEL, setcpu conservative minimum on standby, sdcard powermanagement tweaks, all tasks killed, VBN beta 5 Android Rom, 2.12.50_2 Radio ~ 3% / 5h

Only difference is I am running Energy ROM, but the rest is the same.. I've been using WM due to the poor battery life, as I can't make it through the day in Android.
Solution for 5%/h drain standby problem
I had 5%/h battery drain in StandBy, but I believe I found the solution (it is working for me).
(a "small" copy of my another post)
Solution (need confimation), found somewhere on xda-forum
1. Battery calibration (not sure if this task was really necessery)
2. Charge battery to fulll (green led light expected)
- on WinMo till green led, turn off the phone (shutdown winmo)
- on phone turned off (till green led)
3. boot WinMo and Android
- then remove /data/system/batterystats.bin
Use this commands from Android Terminal (free).
su
rm /data/system/batterystats.bin
Click to expand...
Click to collapse
3. Restart Android
- in that moment I had expected 1%/h drain already
- use battery till it become almost (~10%) empty (just use the phone as usualy).
Thats all.
Propably, after many android switches (new distribution tests) the battery stats was broken - collected partially in different Android instances (on memory card).
Then finally, after 1 week with 5%/h battery drain problem in standby I have 1%/h in standby again.
I think it is standard drain in haret.exe version.
I've seen many people saying they have poor battery life, see now with no changes in windows mobile or android such as using set cpu I get just over 1% per hour. I was asleep for nine hours with my phone in stand by mode with the radio on and I lost ten percent. In the same conditions with windows mobile I'd usually of lost about six percent so there is still quite a large difference. however I am using froyostone version one as my daily os and its manageable, listening to music and using 3g rather frequently and it lasts me the day.
So for me battery life isn't a major problem
Based on the broad range of battery drainage reports (at least ten percent in each category) the problem could be with battery calibration like in lemars post. I am going to try his recmmendation tonight and report back.

Here is my T-MOUS HD2 setup

5.Install and run SetCPU with default config
With a few calls, wireless and autosync on at all time, my battery drops down from 100% to about 80% in 5hrs usage.
data on GSM during standby instead of 3G..
unless i need to surf net or use data intensive stuff, or else for facebook and twitter updates, i remain in GSM data as well as for push mail notifications..
my battery lost is less then 1% while on standby partly because i use setcpu for clock speed setting.. another reason is possibly due to my GSM signal on Max at -60dBm so i use less energy to lock on to the signal..
below are my settings:
Main settings

How do i use Android Terminal?

There are many free terminals like this http://www.androlib.com/android.application.jackpal-androidterm-zxnC.aspx.
Install from Market and on the Android prompt "#" put su<Enter>rm /data/system/batterystats.bin<Enter>exit<Enter>exit<Enter>.
There will be no message after rm command - if there is one, you missed something.
I can confirm that after more then one day of usage I still have ~1%/h in standby. So this solved my problems.
Which Windows Mobile build is the best choice for battery life maximum?
I really like this phone but the battery drain is terrible. I have that verizon extended battery in it(2750mah) but even with that the phone will lose about 10% battery in about 1 1/2 hours during non-use and roughly double that if im browsing the web.
I have Battery Doctor and Juice Defender running at all times and disable anything i dont need to have running. Also, for some reason Battery Doctor does not display my current battery status accurately so i use a basic battery stat widget to know exactly how much battery is left.
Does anyone have any recommendations on what i should do? Apps i should use/not use? Oh and i do keep display brightness down and have done a full cycle charge.
Thanks!

I don't know if this would help/is recommended, but I decided to bump charge mine once. It seemed to help me out, but opinion seems to be split on whether it's good for the phone or not. I also use only friends and calender widgets, and about 4 toggles (airplane mode, gps, wifi, mobile). I generally turn off mobile network where wifi is available. I have been off the charger since 8 am and am at 83% with light use (a few texts, a little facebook, etc). I do use Watchdog lite (to watch for misbehaving apps) and autorun manager (to tweak what runs on startup). I should probably also mention that I have the stock battery.
Turn off 3g manual in settings.
Make the Radio do 3G Only.
Put the phone volume half way.
No vibrate when receiving a text and audio play after the text.
No vibrate feed back when touching the home,menu,back and search button Which can be found in settings>sounds>haptic feedback. Uncheck it
-Monky_1
I have a stock battery.
I use the battery monitor widget to keep an eye on battery use and rogue apps. If I go over 50mA at idle, there's something that's running when it shouldn't.
I also have wifi sleep mode after 15 minutes of idle. And I keep blutooth and gps off. Also LTE only since i have excellent coverage here.
And i use Tasker to turn on airplane mode overnight (turns off all radios) and also silence all alarms, lights, vibration...
I get through about a day and a half of normal use no problem. Once cm7 is out i imagine i will get 2 or more days no problem, as it tends to idle at less than 10mA which would be a dramatic overnight difference.
Starting to mess with my new SGS2, flashing and stuff.
So i figured at some point i'll have to settle on something usable in real life and that includes a fair battery life.
For that one may need an application to gather battery drain statistics over prolonged period of time. In graphed form, with apps draining, charging, trend analysis, reboots/loss of power, etc.
Is there such a thing ?
At the moment i got the DarkyROM2 and it has the short term battery graph. But i want something to span as long as statistics are being gathered (weeks ? months ?)
Ultimate case analysis app of power consumption ???
In my opinion, Battery Monitor Widget Pro is the best battery monitor + including graph with voltage usage, percentage, etc ... it also include battery calibration tool too..
but it dont manage apps that running. in that case, install "watchdog" to manage whats apps running,ram usage,etc ..
both apps is a must in your case.
watchdog by zomut llc ? too much watchdogs on market
Better Battery Stats is what you need, only.

Hey guys, I'm experiencing extremely high AOS usage in the battery stats. It is almost always higher than Display Usage.
SETUP
Rom: HyDrOG3N-ICS 13.05
Kernel: SiyahKernel v3.2.5.1
Battery: Official 2000mah
I've got some UV/UC for CPU and GPU, I don't experience any freezes or slowdown's at all.
I've tried turning off BLN and it didn't affect the AOS usage which means that there must be something else contributing to the high AOS usage.
I've got sync on and some periodic (1hr interval) syncs such as weather. I've got an additional push account. [IMO, this shouldn't be part of AOS]
Does anyone have any ideas how I can find out the culprits for AOS?
betterbaterystats app install an c wats draining....

is that betterbatterystats ? or the normal battery stats in the ics options ?
depending on how much screen on time u have ur next big battery sucker will be Aos (since u stated that u have sync on) if the phone is idle most of the time...
in my case i see Aos usage thru the first half of the day being the most battery sucker, passing afternoon its display and calls with Aos after them and at night i have Aos climb back up top... why? because i leave the phone in my pocket most of the time except for when i need to call/send a msg thru whatever app/sms/mms..... or anything and that keeps the phone awake for that short time and then its back to idle in my pocket and the only thing working is Aos checking email and whatever is on in sync
dont be surprized to see it up top its only natural, but keep track of how much power u lose. Losing 0-5% of battery life an hour on idle(screen off/locked) depending on signal strength with sync on is normal... more than that and i would be looking for any wakelocks or whatever is causing the phone to lose so much battery juice.
i have seen bad modems use even more battery juice just trying to maintain a good signal even with data&sync off and 2g
Not sure how I managed to fix it. There wasn't any out of the ordinary wakelocks. I flashed the 3.2.8.2 siyah kernel and at the same time adjusted the polling rate of BMW. Seems like it was battery monitor widget battery polling rate that contribute to the AOS. I always thought that it would show up as a separate usage stat.
Recently i am observing that my phones most of the battery is used by process called Android system.
Normally this should be screen beacause most of the battery is consumed for backlighting etc.
Is this normal?

I have sometimes the same.
I only used the screen for like 3h but phone is awake like 5 or 6 hours...
And when i loook at stats i see its its waking up. But i cant find any program.
Or what it is....
Odp: Keep awake process battery consumption. ...
Download some app like Ram booster and check out what is it that eats so many energy. It can be an app which is not mentioned separately in the battery usage info, so it is automatically "glued" to the Android OS process.
Wysłane z mojego LG-P760
Use an app that show's battery usage, and try to see what's hogging the battery.
'Smart RAM Booster' is a pretty good app as suggested by fussek. However, I find it useful in killing unnecessary tasks/processes. As far as using it to monitor your battery; I am not sure whether Smart RAM Booster is the best option. You could try 'Battery Monitor Widget' or another app like it.
I would also suggest you get the 'Deep Sleep Battery Saver' app. Usually apps try to periodically update/push data even when you aren't using the phone (which also drain battery). What 'Deep Sleep Battery Saver' does is put your phone into 'deep sleep' so apps can't drain battery while the phone is on standby. You can also set the phone to 'wake up' for a specific interval (i.e every 5 hours) and then go back to 'deep sleep.'
Hope this helps!

No success. ...
I installed battery stats plus and battert monitor widget...
Both shows maximum battery used by android os.
Normally overnight battery use is maximum 1 or 2% but last 3-4 days it is around 20%.Also my phone becomes hot for normal usage also.
In last 3-4 days i installed apps like flipboard, any do, bookmyshow only.
Do youthink any of these causing this problem? But in battery use section they hardly drain 2-3 % of the battery.
I haven't tried "deep sleep battery saver"
I will try it now.

Hmm I don't really see anything out of the ordinary (then again I am no expert at these kinda things). Maybe someone else could give you some input based on your stats?
However, I noticed from your screenshots that you are connected to the Edge (2g) network. Edge is known to drain the battery a lot compared to 3g/4g networks. Do you have any 3g/4g networks in your area?
-Protomartyr
Yes i have 3g network in my area. ... but i was thinking that 3g takes more battery than 2g...
Because whenever i connect to 3g network the phone becomes hot.
Sent from my LG-P765 using xda app-developers app
Yeah sorry I confused myself. Usually you get better battery life with 2g (but at the cost of speed). What I meant to say is that when your phone switches between 3g and 2g, this switching back and forth can cause quite a bit of battery drain.
