Hello all,

Does anyone else experience a quick battery drain with newest beta2

I believe it has something to do with HSDPA(3G) as android reports time with signal as 50%

maybe it keeps dropping / reconnecting and thats causing the battery drain.  

anyone else see this?

I've been trying to get around this problem for the past couple of weeks, and here are some options:

1) Run 2G only - This will eliminate the time without signal being 50% problem, but you are on 2G.  Press the 2G only button, then turn on airplane mode, and then turn back on, and you will have just 2G

2) SetCPU - I've started using SetCPU this past weekend and it's pretty good at helping to extend the battery life. I set it such that the phone only runs 133-66Mhz when the screen is off. I was able to get almost 10 hours with some regular usage.

3) There seems to be some issue with the i8000L sleeping properly. I've seen others from Canada on the forum having these issues.

Is 2G even an option for Bell/Telus/Virgin Mobile users?

Those carriers don't offer any 2G service...

Hi,
I have reduced my "Time without a signal" from 50% ( and more ) to 0%
changing my "Set preferred network type" from "GSM/CDMA auto (PRL)" to "WCDMA preferred".
My Italian operator is H3G that operates only in 3G bands ( in roaming for 2G ).
Procedure :

1) *#*#4636#*#* ( in the phone dial pad ) ,
2) Phone Information ,
3) Set preferred network type  >  WCDMA preferred ,
4) Turn off radio ( with the little button just under ) ( waiting for radio turning off ) ,
5) Turn on radio ( with the same button just under ) ( + back , back ... ) .


May be preferable

ro.telephony.default_network=0

in

build.prop

???

... sometimes yes, sometimes no ... I dont know.
However, next time, try to apply only the points 1),2),4),5) without the point 3),
to me, now, it seems the same.
Booh !!!

Guys it is true that its showing time without signal 50% .. but just look at the timer .. its just double the real time of the device being awake (weird huh ??) .. so technically time without signal is almost 0% ..

... yes, you're right,
turning off and on the radio ( the only two sufficient operations, other operations are ignored ) the time results correct.
But also decreases the percentage of battery used for the "Cell standby", and this measure should be time independent.
Currently in standby ( over night ) I have a consumption of about 12% of battery in 8 hours with "Background data" turned off.
That's not too bad   .
