I have an old 16GB iPad that has grown painful to use. It's slow, unresponsive and I have to manage the storage pretty regularly. I think it's running iOS 9 which is the last supported iOS. I really only use it in bed, keep it on my nightstand. Check email, iMessage and watch TV via Xfinity (which surprisingly it can handle after slowly navigating to a channel. If I wipe it clean and reinstall iOS and a few apps will it run faster?
