@turbovomit don't use the .deb versions they are very old just install the patches from HAM or FAM or apt-get install batterypatch speedpatch @zurrain101 there are custom profiles (overclock, underclock) buut they have the same voltages as the default profile so i avoid reboots @ ALL what's in the newest batterypatch: When device is locked : or system is inactive while the keyboard is closed 1-) vfs_cache goes to 10 2-) multiple processes are paused (which are known to use CPU in standby) 3-) change to underclock profile which has vdd1 vdd2 enabled powersavebias=20 (but with the stock voltages) When the device is unlocked or brightness is on doesn't require the keyboard to be opened 1-) vfs goes back to 100 2-) overclock profile is loaded which has vdd2 and conservative mode with powersavebias=20 3-) the multiple processes are started again PS: if you are downloading or installing something which takes a long time and you locked the screen while you don't want batterypatch gets activated and you don't want to make N900 slow in standby just open the keyboard and lock the screen then nothing happens if N900 is in standby (while keyboard is opened) and if you are done simply close the keyboard and lock the screen so the batterypatch gets activated
