I've bought a xperia arc SO-01C (NTT DOCOMO). it had android 2.3.4. but i flashed the L18i firmware. now its battery drains very fast (10% in phone idle per two hours). sometimes i feel a little bit of heat on its upper side. is it a problem with the new firmware? can japanese version arc run ics firmware of LT18i? there is no any other problem with it.
Hi, suggest removing and re-inserting battery for a start. Monitor phone after few full charges, you should be able to conclude after these steps. Good luck.
