Same as everyone who are facing the mega battery drain issue and overheating, I was also getting my battery drained really fast while playing COC (Currently using Samsung Galaxy S2 aka i9100). Somehow coc developers have not fixed that bug.
There is a workaround for it, which obviously need root to manipulate the freq of Device. Use apps like nofrill cpu control or setCpu to underclock your device to 700-800 MHz (or play around these ranges). It will hugely improve the overheating and battery drain issue.
Conclusion: Simply Utilize the OpenSource power of android.![]()
