Battery drain

Hi! Naturally this iOS won´t really fix your battery drain.

But I can provide you with a few hidden settings that would help your battery last a little bit longer.

First, try turning off background app refreshing, it´s on the "general" section in settings.

Then, try removing Siri and spotlight searching for every app.

Next step, go to privacy, location and then try to disable location for as much apps as you can.

Below, try removing some unnecesary location services.

And last, but not less important, remove back up over cellular on the cellular data section. Remove the push email option. And remove the cellular data option on Photos.

Hope this will help you!
