I have noticed a dramatic battery improvement! I can last the day with 10+hours of moderate usage.

But i have to enable smartreflex every now and then because it automatically resets itself to normal. I dunno how to enable it permantly.
You can enable smartreflex permanently by editing the values in /etc/pmconfig.

I tried typing /etc/pmconfig into the xterminal after i gained access to root but it said

"/bin/sh: /etc/pmconfig: permission denied"

So i'm not sure what to do.

And since today I unplugged my N900 from the charger around 10am and its now 9:34pm and the battery is 43%.

Thats after a few text messages(about 10), a few calls(30minutes total), emails getting checked every 15minutes from 2 email accounts(alot!), playing SPBBRAINEVOLUTION for about 20minutes, with my Foreca weather widget set to check weather every 1hr. Brightness on 2 bars, with 3g on most of the day with wifi and 3g connection switching between them.

I never would get this without smartreflex. Just letting everyone know

You need to use a text editor like vi to edit the file.

If he's having that trouble, I'm sure Vi is gonna be a major PITA for him.

Here's some help for the guy who wants to edit pmconfig

1) It's a config file, not a command
2) Install Leafpad
3) Open xterm
4) root
5) leafpad
6) open config file you want to edit, edit, then save
7) smile and hope it doesn't make your N900 reset itself all the time.

Hello,

This is my first post here. My battery, even though it's new and I'm charging it for the 3rd time, is very good in comparison with others I've read (or not?). I've written down each and every action I've done.

In summary:
2.5 hours of WiFi (which 1 is idling connected, 1.5 in use)
15' in calls + 5' internet + 2 sms on 2G
10' internet on 3G (ok, 3.5G) [and used Pidgin for IM]
Installed 4 applications (over WiFi)
Uninstalled some widgets/apps
Installed all updates
4 reboots
Constant checking of battery level using BatteryGraph
CPU was downclocked to 500mhz when not in use with QCPUFreq and SmartReflex enabled
My provider has crappy signal, in both 2G/3G
Used Terminal to modify some uKeyboard settings (which failed)
Powered off for the night, and opened in the morning (5th boot)

It took 21 hours of use (not counting the 9 hours it was powered off) to "beep" for low battery, and I put it straight to charge.

Anyone who's having problems with the battery life should install batterygraph to see if something is keeping cpu working all the time. On my N900 the cpu stays 0 % load 95 % of the idle time (after reflash!). If something is keeping cpu around 3 % - 10 % it quickly discharges the battery.

People should also consider reflashing, this made the biggest change to me (with the same firmware). Good instructions here:

In my case I left the mass memory intact, I guess that it wont affect power consumption.

Xorg process is consuming 3-7% cpu all the time.....
