Battery dying quickly- ideas?
I have an iPhone 7, bought on Black Friday 2016. Recently, the battery will start to die quickly (it’s gone from 100% to 89% in 2 hours, when I haven’t been using it and have no apps open, for example). Battery life is at 92%, working at peak performance.
Is this a known issue? I don’t want to have to buy a new phone or pay through the nose for a new battery, if I can help it. I actually like having a home button!
