Iphone 5s battery drain even in airplane mode
Hello all,
Have iPhone 5S from UK. IOS 7.0.3 installed. Experiencing the following problem.
I noticed that the battery drains too fast on the 2 days old phone.
When i go to sleep i put alarm on, close all apps, switch off the sound, put the device in airplane mode. When i wake up, 8h, the battery drains 10% or more. On the iPhone 4 this wasnt an issue, max 1-2 percent, but in most cases it remined same percent. Why is this battery draining that fast with nothing running? Any solution?
Also when phone reaches 1% it seems to sit more on it than it should before recharging, as if 1% is the same as 3% i can compare this because i see how fast percentages deplete before that.
I am having a hard time believing that this is the device? Or is it? Should i reset? Delete some apps?
Please help....
