[Desire Android Development] berre:
OK here's my detailed experience with the battery, a lot of reading but might be interesting to some people.

To me it looks like this ROM is defenitely getting good battery life (compared to my stock sense froyo ROM) but I can't compare to any previous redux versions since this is the first rom I flash :-)

Here it goes:

charged until 100% last night @ midnight (I think just barely because batt dropped to 99% a couple of seconds later)

set my alarmclock + tested 2 or 3 times (snooze volume buttons etc)

switched of mobile data and wifi

=> Battery @ 98%

Left overnight, woke up around 5:30AM, at that point my alarmclock has gone off a couple of times :-)

=> Battery @ 96%

Arrived @ work around 7AM, switched on mobile data and wifi... both didn’t work, for mobile data I’ve changed the settings for the power toggle, for wifi it was normal because I didn’t have any defined

Then some browsing in the market, downloaded "Quick system info" and played around in it for a minute or 2

=> Battery @ 92%

After morning coffee and mailbox check it was 7:43 and time for some stress testing and downloading a bunch of apps from the market (while on WIFI)

=> At 7:48 (after 5 minutes) 1% battery drop to 91% after checking in Astro which apps I needed to reinstall and installed 1 application

=> At 7:52 (after 4 minutes) 1% battery drop to 90% after installing 8 apps

=> At 7:54 (after 2 minutes) 1% battery drop to 89% after installing 6 apps

=> At 7:57 (after 3 minutes) and after installing 7 apps, battery is still at 89%

So a total of 14 minutes of constant screen on and installing 22 apps from the market via wifi caused a drop of 3%

At 8:07 I was at 88%, and I started the config of my apps, below you can find the timeline

8:12 87% (facebook, lookout scan)

8:14 86% (sync tv guide)

8:20 85% (various apps)

8:23 84% (various apps)

8:27 83% (various apps)

8:32 82% (various apps)

So after 25 minutes of constant screen on and syncing and quickly opening/closing apps there was a drop of 6%

08:45	82% after sent 1 text message

09:03	80% after moving a bunch of apps to SD card

09:15	80% after checked mail

10:00	79% after sent 2 SMS, received 2 SMS and sent MMS

11:25	74% after 2 missed calls, one SMS received, 2 calls of about a minute each, checking calendar app a bit

11:40	71% after fiddling with the phone for about 5 minutes (short game and some icon organizing.)

12:20	70% just checking in between :-)

13:15	66% after uninstalled 3 apps, installed 3 app + some fiddling with lockscreen en widgetlocker, taken a picture, about 12 minutes screen active time in total

13:30	64% after received a phonecall of about 2 minutes, downloaded an app from the market + played around in it for about 2 minutes

14:00	62% after received sms + played around in term emulator for about a minute or 5

14:45	60% after received 3 sms + sent 3 sms + installed app from market + fiddling around for a minute or so

14:55	58% after 5 minutes of surfing the web (wifi) ; I must also admit that browsing is pretty fast compared to my stock ROM on the same wifi access point

15:00	57% after switched on bluetooth (wifi and data network remain active however wifi signal is lost)

15:15 57% after BT connected to my car parrot + checking mobile speedtraps (short data connection)

In my car I

- called one person (no answer)

- checked my voicemail

- called one person about 30 seconds

15:43 Arrived at home, switched BT off, wifi off and uninstalled one app

Battery at 55%

At home I

- called one person (no answer)

- sent 2 sms's and received 2 sms's

- about 5 minutes fiddling (screen on)

- 10 minutes browsing the internet ............... this had the biggest impact on battery since I have poor reception and am constantly hopping between different antenna's

This left my battery at 45% @ 16:25

Here I stopped my test because I had stuff to do :D

Cheers
