iPhone 6s battery is not displaying correctly
Hi I only got my 6s a week ago and I've started to find the battery is playing up. I found that after being plugged in over night it stayed at 37% but when I turned it off and on again it was 100%. Then the next day it has stayed at 46% but after turning it off and on again its now saying 9%.
Is there a way to fix this?
Seen as though this is a brand new phone, should I enquire about a replacement?
iPhone 6s, iOS 9.0.2
