Cyanogenmod is EATING battery life

[desura]

I finally got around to wiping out touchwiz on my galaxy tab s 10.5 and putting on cyanogenmod. Overall the tablet is more responsive and less irritating to use compared to touchwiz, which made it feel sluggish.

The only issues so far is that hardware video acceleration doesn't appear to work all that well, or at least it takes a while to initialize for mxplayer. More worrisome is battery life is really bad right now. I just saw it drop from 12% to 8% within a span of ten minutes.

Looking at the cyanogenmod website, it is only showing the nightly builds and not any official release builds. Any advice?

look at xda, and see which version has the fewest issues/bugs

cyanogenmod is basically unofficial firmware... it's never going to be 100%

Use cpuspy to see if the tablet is going to deep sleep when its off, if its not use wakelock detector to see what's causing it to not goto sleep.
CM on exynos is never going to run right.

Cm has terrible battery life on my Samsung s4 too. Still looking for a nice rom for it....

sometimes you can't beat a rooted stock rom.

I can't speak to CM but COS on my OPO is very battery friendly. I'm on the latest build (12-1-YOG7DAS2K1) for 4 days now and things have stabilized since the wipe/flash. The battery lasts me all day long.
