hey all sifus,
sorry for a noob question. i just wanna share my problems with my 1 month Samsung Galaxy S2, first of all, it keep restart (or perhaps crashing?) when i open some of the application (usually, games and some of the heavy apps). secondly yesterday, after i woke up at 3 pm, my battery life came down from 92% (i had charge it last night) to 35%?? what the? i try to find out what cause the battery drain so much and i found out the ANDROID OS used up about 92% of my battery power? (i used battery indicator in this cases) , but how the android OS drain up so much afterall im sleeping at 4am until 2pm? it just 8hours duhhh. how can possible this problem occur sifus? hope for your guidance.

and usually after i woke up from sleep my battery will be from 90++ percentage to 80++ something.. just wondering fi it is the battery problem?
