Hello! I just bought a Nokia N900 and I f**cking love it. It's the perfect hacker's phone/tablet. Seriously great.

... I love every part of it except the dismal battery life.

Example:
  • Got out of the house at 4PM with the phone @ 100% charge.
  • I had it connected to wifi for 5/6hrs light usage -- just my twitter client and xchat, plus the odd webpage. It was totally idle for most of the time.
  • Had it charging for 1h+.
  • Played 45min of Ur-Quan Masters (try it if you haven't -- great game).
  • Sent 20 or so SMS, chatted a bit on google talk, made 15min worth of phone calls.
  • Modest checks email every 30min or so.
  • Played with the GPS for about 5 minutes.

It's at 25% now.

I have it locked at 2G. My wifi power-saving is set at maximum. This is kinda bad -- I don't want to abstain from using the phone so it can last me a full day

Here's a htop screenshot of the idling phone:



Here's my kernel-config:

Code:
[00:06:17 root@Nokia-N900:~]
# kernel-config show
current kernel configuration:
current frequency: 500
supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150
min. frequency: 125
max. frequency: 900
avoid frequencies: 125
active frequencies: 250:24,180 500:34,360 550:36,400 600:39,430 720:45,520 805:50,600 850:52,600 900:55,600 950:60,600 1000:60,600 1100:72,600 1150:72,600
SmartReflex VDD1=1, VDD2=1
governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0
Any tips ... ? Can this be due to advanced-power? I also have speedpatch installed, just on a trial basis.

By the way, the battery is an original Nokia one, with very little wear.

Thank you very much for your time!
