Whenever I restart my iPhone, the battery drains?

Like I said before, i have an iPhone 7 Plus and here's another issue with it. Whenever I restart my iPhone, the battery goes up a bit and suddenly it just drains. What usually stops and turns it back to normal is putting the screen dark for a couple seconds and then putting it back to normal brightness. Is there anyway to fix this on my own or is it time to get a new battery/phone?

Have you tried charging it underwater?

Charge your phone or consider replacing the battery.

The process is very tedious.

  • My iPhone 5 battery drains during lock? Whenever I sleep, I never charge my iPhone, so it's basically next to me on lock. I think I slept to it being 38%. I slept for 11 hours (yup, I'm a potato.don't worry, this was only yesterday) and the next morning, I woke to the battery being like 25%. Just wanted to know if this is normal?
