USA Today contributor Jennifer Jolly shows us some absolutely genius ‘re-uses’ for an that old iPhone that you have lying around the house.

An hour after upgrading to iOS 11, my iPhone 7 Plus phone was at 30%. It was 11 a.m. and I had barely used it.

So I went back to expert advice from Scotty Loveless, an Apple consultant at who helped me with iPhone battery problems earlier this year. From earlier tips and tricks he taught me, I was able to reclaim my battery life once and for all. (Or until the next update at least.)
