AGPTEK Rocker
squidman:
I am also having the issue where the screen doesn't turn off all the way, only the backlight. So the battery life is terrible. I am using an AGPTEK rocker not a benjie.

So what is the runtime with your device exactly? Have you run the battery_benchmark plugin?

Anectdotally, my T6 with rockbox has less than half the battery life as the (very well-used) Sansa Clip+ it replaced. It doesn't survive an 8-hour drive playing low-bitrate audio books (mp3), whereas the latter would easily last for the return trip as well.

I forgot to run the battery bench for the first hour of playback but in the bench I got 6 hours and 34 minutes of mixed flac, opus and mp3 v0 playback. So I got around 7 hours and 34 minutes of playtime.

Unfortunately there is little I can do about battery life. Kernel on agptek doesn't perform freq and voltage scaling. I try to powerdown lcd which reportedly doesn't work for some (although lcd itself eats only tiny amount of power compared to backlight). Without kernel sources I see next to no room for improvement.
