My iPhone 5 battery has been lasting less and less recently. So much so that I'm having to charge it 2-3 times in a day.
So before I investigated my options with Apple I decided to reset my phone, download everything again and see of things improved.
They have do far. I've been using it pretty heavily the last 4+ hours and I'm down to 34%. But that's been heavy use with the screen constantly on.
It actually wasn't too bad while I had my weather apps off. But as soon as I fired up those the battery started going down faster.
I'm going to see how it does tomorrow and then decide if I go to Apple to see what can be done.
