Battery drain on brand new iPhone 7 with iOS 11.2.5
I bought this brand new iPhone 7 couple of days ago and the first thing I did was to restore the phone to 11.2.5 through iTunes. The phone was shipped with 11.0, If I remember correctly.
The phone looses about 13% in 10 hours of idle overnight. I left my mobile data on. I have Whatsapp, instagram and google maps installed on my phone. Notifications are blocked, location is off, background app refresh is off, mail in manual fetch and every other possible battery tweaks. The cellular signal was about 4 bars on 3G. Turned off 4G. Still the battery drain is high.
In similar conditions, if not with more apps and notifications on, my 5s running 10.3.3 gives me more battery life.
Is something wrong with my new iPhone 7?
