I am using iPhone 4S from last one year. From last one month the battery
back up I am getting is 4 hrs . I am not using 3G network only 2g . When
the battery % comes to 45% the iPhone immediately goes to off & I have to
recharge. Initially it was working upto 3-4% of battery life.
Really I was fade up due to this poor life.i am using all tips for battery
life improvements still it's problem.
Give me the solution.
