and the battery life not fine.. i know that it's not new. but not like this case..
its always change.. for example. one day i am using 5 screen hours includes music and net. wifi. and its work for full day. in next day. i am using 3 screen hours. not in use. and the battery need charge after some hours..
the brightness stay the same. no apps changes. install or running.
what can to be?.. rom problem? battery replace?..
