gps is only using power if an app or widget is using it

merge your duplicate contacts
rootsh
marina theme
humanity theme
angry birds

a) question, has a theme a high impact in the battery consume? Before I had the humanity theme activated.


Well, let's see how is battery consumption now. Widgets in the 2 desktops, battery, ip, and calendar, All of them not automatically being updated, with the exception of calendar, but only 3 times per day. Brightness to 1, marine theme activated, static (downloaded) images as background, 3G always connected, wifi disabled, GTALK enabled (skype disabled), GPS disabled.

11:59 -> 54%
I switch off, I switch on, and then
12:02 -> 34%
12:22 -> 36% ... ok, batterygraph says the same, so I'll better wait to have full battery again.

I post it anyway

i'm getting on average an estimate of about 4 out of the charger before the battery indicator gets low enough for me to worry, this with almost desktop level usage, wifi on all the time, skype too

I havn't allowed it to shutdown from lack of charge nor iddle for too long unplugged.

I probably have a few things running in the background that shouldn't, i've been installing lots of stuff......

13:18 57%
14:42 53%
(0.05% / min)

surf 2min, pidgin 2min (quit, not just close), fam 5min
14:56 -> 50%
(0.21% / min)

15:26 -> 47%
(0.10% / min)

<5 min surfing
15:59 ->41%
(0.26% / min)

16:20 -> 37%
(0.19% / min)

16:49 -> 34%
(0.10% / min)

It could appear than battery is somewhat better now, while it is like the whole so was faster as well.

would there be a way to limit the power of the amplifiers of the receivers even if that make the signal worse?

I think that may be a bit of an oxy*****, as if you lower the power and the reception is worse it has to try harder to stay connected so likely uses just as much if not more power in the long run.

I'm guessing demodulating and decoding signal uses more anyway. When wcdma was announced, the designers "bragged" that it was so adsvanced/complex, only the fastest personal computers (of the time) had enough cpu to decode it.

The command channel is probably easier to decode since the phone uses almost no power in standby.

I noticed the low signal power consumption myself too. I was out at sea some 30 minutes by speedboat out, and the signal was very weak. With the mugen battery I get over a day with xchat/irc and such open. That day I got less than 8 hours..

the idea is to limit how hard the device will try to boost the signal when it's weak, not just make the signal itself weaker
