If your battery life is terrible after updating to iOS 11, restore your device with iTunes.

seriously. iphone 5s getting terrible battery life after updating ota ios 11.1 ios 10.2.
i'm talking 3h 30m 4h of usage. battery go down 1% every 2-3 minutes. drain unreasonable amounts when phone locked , doing nothing.

after trying no avail restored ios 11.1 using itunes , set new iphone. wasn't expecting surprise battery life normal me on 10.2 , previous versions of ios: on 6 hours of usage same apps , settings always. that's 2 hour difference on ota update.

if having terrible battery life on ios 11, try restoring itunes. if still have bad battery life restore itunes , set new iphone (skip backup) redownload apps , setup settings before.

yes, know restoring via itunes pita might worth time if nothing else works resolve battery issues.
