Hi, need to know something quick guys . I dropped my htc one m8 gold ...... but phone is all fine as had amzer hybrid case on . After that i got that themes blinkfeed update,etc . Only thing i feel as change after dropping is that battery drains from 100 to 99 % very quickly like in 1-2 mins of use , is that normal ?! And even in standby battery drains, I feel like more than normal it drains. Could anything be wrong with the battery after dropping ?! I do am using a theme though, so could this be because of the new theme feature that i am using?!

Will highly appreciate a reply .
