There are times where I need to record a lot of continuous video. I've found battery life to be insufficient for this. Is there anything I can do to squeeze out every bit of battery efficiency?
The biggest offender is probably the screen. I don't need it to be on, as the phone is usually propped up against something while I do the stuff I'm trying to record (weight lifting in my basement; recording myself to check for correct technique). Codec choice also comes to mind as potentially CPU intensive and thus battery draining.
