reinstalling the original "Market" does not solve the problem. It works only one time, and then replaces itself with "Play Store" again. So the "Market" disappears and needs to be reinstalled again and again.
Regarding the mA consumption - don't have numbers right now, but, again, it's definitely more than original/Energy Win ROM.
im guessing that most win roms would have better battery life....but how high is the consumption?? check numbers
