iPhone battery
my iphone 7 consumes battery even off. I always turn off at night before go to bed. And yesterday he had 50% and now is 25% battery. it is not normal. This phone has only given me problems.
Ssmariana,
Go to Settings > Battery and scroll down to BATTERY USAGE to see the apps that are consuming your battery. If any of the apps have unusually high usage they can be shut down (double tap the Home button, scroll left or right to find the app, then swipe up to shut it down).
As time goes by you should be able focus on the problem apps. Usually it is a rogue app constantly running in the background. You should then be able adjust the settings for the problem app to solve your problem.
Let us know how it goes.
