Can anyone help with this? Lots of battery drain with ICS b927.
I have disabled 3G, wifi, gps, bluetooth, sync, removed lots of apps.... But can't stop battery drain.
When i had Gingerbread this didn't happen.
See attachments please.

Have done that too. Can't find out what is waking the device.
I 'm "new" to batterystats. Never had this type of issues with any phone/rom. Just with ICS and G300.

I think 20% down in 8 hours is not so bad, not sure if there is really a problem. There were ROMs (e.g. on the Blade) that killed the battery completely within that time...

My best result with B927 is 30 hours until being at <10%. That was with 3G On, Wifi On, BT On, using A2DB Streaming for more than one hour and frequent use (checking mails etc.). I am really happy with this. And in contrary to the above my feeling is that Wifi has only low impact on the battery which is really nice as it prevents you from switching it off and on manually all the time.

Regards
Fabrizio

I use android for a very long time and NEVER have seen nothing like this in my phones.
Battery is draining VERY fast for what i usually do.

Thank you for your help but you are all missing the point here.
With Gingerbread this doesn't happen with same usage/apps. There is something wrong and can't find out what.

i used full batery to download angry birds-play for 30 mins-talk 10 mins and my batery was at 9%, so there is an issue. WIFI was dissabled.
With all other roms i never had that problem, with wifi active, using gps and playing it took 2-3 days to reach 9%.

Playing games totally destroys battery life IMO. Maybe once we have true OpenGL things may improve.

I have had 2 and a half days with Wi-Fi on before needing a charge with moderate use.

BetterBatteryStats should show you your partial wakelocks. Maybe something is stopping your phone sleeping?

i play games only 1nce on week or even less, but in all other roms i never lost so much batery. Just to know i had batery at 80% before 1st post and now im at 75%, i didnt played/called/wifi so there is a big issue. my phone is 2 months old so we cant talk that my phone/battery is old.

I will go back at 926 just to save battery life

I figured out my battery problem on B885: in some situations the phone would leave the audio amplifier on. If you listened to the speaker very closely, you could here a faint noise even when the phone was in standby. The battery stats did not display the battery use correctly, but obviously the battery level still goes down, even though it shouldn't really.

So I think it is worth watching for "hidden" battery use.

Ok.... removed some more system apps, disabled the only two widgets i use (music and radio).
New test again :) Lets see if there is any difference. I have 1/3 battery life than what i had with gingerbread. ICS can't be that bad, or is it?

I've openned/used/closed the usual apps and i'm waiting for a full charge to do another run on betterbatterystats.
I really don't want to go back to Gingerbread, but if battery issues don't stop, will go. When i had b894 all was fine.
This thing runs smoooooooth and it's pretty, but sucks all the power!!

@ tillaz & runlevel5
here it happens the same, but only about 3-4%

after experiencing this i don't think the battery life is bad, its just been shown totally inaccurate...
battery readings are a total mess

Battery life for me on B927 is by far the best battery life I have had on an android device, and this is with heavy use.
