Hi there,
Having huge battery life problems since updating to 11.1 (OTA). Is it OK to restore over iTunes and try all things again? Is there be any effect? It's huge drain not overnight but in usage also. 20 to 30% worse than 10.3.3.
8+ and battery drain here. Back to 11.01 and is fine. Just usage when phone is on standby. So 2 hours for 14 standby on 11.1.
