I am not sure what you are asking. I will take a stab at answering this question: How does the battery life compare to the life with a GB ROM? I was using Overcome 4.01 (I could never get 4.1.0 to work) and I saw a slight degradation (at the end of the day the battery was down to 35% instead of 40%) until I learned how to turn off the lights on the capacitive buttons. There are two ways to do this:
- Go to settings/system/tablet tweaks and turn capacitive buttons off, of course if you do this the buttons won't work at all
- Hold the settings button down for five seconds, this will still allow the buttons to work but the lights will be off
Now I can't rea lly distinguish any difference in battery life between the Overcome ROM and the CM9 ROM. It is important to note that I never ran my Tab with the stock ROM so I can't compare to that. Hope that helps but YMMV.
Edited in: One other thing, I never mess with overclocking, etc as I don't play games and everything seems to work fine so why fix if it isn't broke?
Cheers,
Fred
Alternatively, you can use 'LEDs Hack' app to turn off the capacitive lights.
