iPhone 7 Battery Draining Fast All of a Sudden? Here’s the fix

My iPhone 7 battery draining fast suddenly. I don’t know why. Last night I saw the battery percentage. It was 98%. But today morning it was completely drained out. There was only 20% battery on my phone. I didn’t even touch the phone throughout the night. It happens only after upgrading my phone to iOS 11. Then one of my friends suggested I try some solutions to fix this issue. If you have the same issue, this article will help you to fix it.
