iphone 4s standby and usage time the same
Hello
I have an iPhone 4S. I charge it at 1.00 am and sleep. When I wake up 9.00 am in the morning, the phone has 8 hours stand by time, and 7 hours 58 minutes usage time. And its battery is about %70 but my father's iphone's battery is about %95 at same conditions.
So, the phone is using itself while I'm sleeping! Did anybody see a problem like this and solve?
I tried these :
- I reset network settings, after reset all settings.
- I restored the phone and set as new iphone.
- I thought that one app can cause the problem. So I didn't download any applications after the restore. The problem is still happening.
Thank you a lot.
iPhone 4S, iOS 6.1.2
