This page aims to document "power user" techniques for extending battery life, i.e. automating various aspects of the phone's behaviour with a view to extending battery life. It is currently a stub/work in progress; the aim is not to reinvent the wheel but to draw together a variety of approaches to battery saving.

Over on the [[Overclocking]] page, Fecn describes a set of scripts to modify the [[Kernel_power]] settings on phone lock/unlock. These work well, but do not suit my situation.

Techniques in the "invasive power saving" section save power by intentionally limiting the activity and/or functionality of the phone. This can have unintended consequences, so be sure you understand what you are instructing the phone to do before you do it.
