Besides overclocking, you can now install battery and speed patches to increase the performance on your N900. These guide will be broken down into 2 parts.

1. Speed Patch

First install it from Xterm using the following commands

sudo gainroot

apt-get install speedpatch

After installation, it might take from 2 to 4 reboots before the patch can be applied to the phone due to a bug. To check whether the speed patch has been applied, run the following command

ls  /dev/cgroup/cpu/user/

Then you should see some listing of files. Or when there is no error after installing for an instance.

If you are having the xterminal problem and it disappear after xterminal is loaded then do this to fix it

rm .cache/launch/com.nokia.xterm.pvr

If unexpected reboot occurs, the speed patch would be applied on the next proper reboot. To remove the speedpatch, just simply type this command:

apt-get purge speedpatch

2.Battery Patch

The patch works practically by going to an underclocked profile when keyboard and screen is closed. An overclocked profile is activated when screen is turned on. The patch can be temporarily disabled even with the screen off is by turning the screen off after opening the keyboard. This tip is especially useful when you are downloading some stuffs in the background and doesn’t want it to pause the process.

To install for kernel power users :

apt-get install batterypatch

To remove:

apt-get purge batterypatch

To install for non kernel power users:

apt-get install batterypatch-non-kp

To remove :

apt-get purge batterypatch-non-kp

To check whether battery patch is applied :

sudo gainroot

echo 1000 >> /proc/sys/vm/vfs_cache_pressure

Then lock the phone and unlock it then enter this command

cat /proc/sys/vm/vfs_cache_pressure

If it shows 100, then patch is applied.
