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

How much improve? mine last over 24hours, and on wifi almost all day long.

My device has more than 25gb of music and 5gb of photos...
Got a 30% or so improvement

how long does it last? I can easily get more than 24hours with normal usage.

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?

how do you edit and save the rcS file using midnight commander? i can locate it edit it but when i click save and it says i cant save?

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.

I'm interested to know if this has an impact on video recording frame rate and stuttering problem occured before configuration to swappiness

Been there, done that.

Not sure. Could you please give some explanation about this?

And this too?

Thanks!
