Finally got a real improvement on battery life
 
I know that's kinda of known, but since it's a compilation from various posts, I would like to make one with the tips:

I'm getting a great battery life with these tricks:
1) Change swappiness and page-cluster to the minimum you're comfortable with (mine is 15 and 1, respectivelly);
2) Disable indexer watching and indexer on battery.

The resources:

1)http://talk.maemo.org/showthread.php...ght=swappiness (edit /etc/init.d/rcS)
2)install tracker-cfg and read the help, configure as your needs

Hope that helps more people ;)

I have terrible battery life with chat on. Will this make a difference or is this one of those things that prolongs the battery as long as you don't use the device as intended always on device?

It will.
Less swappiness = less swapping = less use of eMMC.

I'm implimenting this with my small python script :)
My script has:

Radio Region change to world wide, vlaue 4
Swappiness level to 30

The script will automatically start up and activate those setting every reboot. So no need to touch rCS file.

Which avoiding people from breaking their device.
