Battery Life
« on: July 14, 2006, 08:59:30 am »
Seems like OZ drains my battery. Primarly I use Z to read books. While I was under pdaXrom, I can read 3-4 days and battery was still on ~70-80% (1-1.5h per day).
Now, 1-2 days, and 50% battery off!

ps: top doesn't show "idle" process, so it seems like nobody issue "idle" to CPU in OZ...

Battery Life

See here: https://www.oesf.org/forums/index.php?showtopic=20464

The question is really whether the eventual battery life is the same. With OZ the battery voltage-percentage lookup table has been changed so that the percentages are linear from the maximum voltage to the minimum rather than the large 100% deadband that occurred for the original Sharp kernel (which I assume pdaX uses).

You should either compare the actual battery voltages (using /sys for the 2.6.x kernel OZ kernel, not sure how on pdaX), or run both kernels until the machines switch off and see whether there is any difference.
