DO NOT USE, I repeat DO NOT USE either batterypatch or speedpatch, it will bring you nothing but troubles. There are ways to improve significantly your n900 battery life, but crappatch and batterysuck are not amongst them. Search the forum on how to install kernel-power and how to enable SmartReflex.
Hy to all. For me the speed patch realy works. It has no placebo effect as some users says. My N900 was verry slow before de patch even though it was set to min 900 mgh and maxim 900 mgh thanks again man .
