    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.

    First, is there any way you can return the phone and get your money back? If you can't do that, did you try going into: Settings, Touch ID & Passcode, and disable Touch ID to unlock your phone?

    Thanks but tried turning it off. I bought it advertised as battery discharging quickly thinking it just needed a new battery but seems it's more than that. Having researched I'm convinced its a software problem but the only solution i have found is to jailbreak it and it can then be overridden. I didn't want to go the jailbreak route but may have to.

    How do you know that it's TouchID?

    I don't know 100% but seems a common problem researching on internet. I have ordered a new battery just in case.

    TouchID causing battery drain? As many issues regarding iPhones that get discussed here that doesn't really seem to be one that shows up much, let alone be something common.

    Hi, I've been researching it for few days and there a large number of reported problems where home buttons have been replaced by non-Apple repair centres rendering the Touch ID inoperative and as a result battery drain occurs. Disconnect the home button and drain stops so it's either Touch ID or something to do with the home button.

    How have you diagnosed that Your 5s has a faulty Touch ID? does it just not work?

    It is possible this is the cause of the drain, .. when I phoned Apple support about a standby drain problem on my faulty iPhone 7 the senior advisor told me he had come across a case where the Touch ID was the cause of standby drain and not the actual battery itself and sometimes it's hard to find the cause.

    Been running further tests and definitively the home buttom. Once disconnected no drain at all. Reconnected and starts draining again. I left it disconnected twice today for 4 hours and then again for 2 hours and percentage remained unchanged on standby only connected to wifi. Reconnected home button flex and draining at about 20% an hour.

    I've no idea how to fix the problem though.

    Have ordered a new home button assembly to see if this makes a difference but I suspect it won't. My research shows it is the phone trying to monitor the fingerprint reader but can't as the button has been replaced. This loop cause the drain. Being synical I suspect Apple do it deliberately like the error 53 on the later phones to stop third parties repairs.
