Hi, hoping someone knows a fix for this. Bought a 2nd hand iPhone 5S and Touch ID not working. For some reason this is causing a massive battery drain (losing 15% an hour when on standby). Using normally the battery is fine, only excessive drain when on standby. I believe the phone is constanty trying to monitor the Touch ID and because it isn't working it is draining the battery. Looking online it seems this affects a lot of people if doing a 3rd party home button replacement which then disables Touch ID. I believe there maybe a jailbreak solution to remove a daemon to stop the Touch ID. Also disconnecting home button stops the drain but you then lose function of home button. I'd appreciate any ideas to rectify this issue. Cheers.
