Hi guys,

I've noticed that TouchID becomes less responsive when it's charging. It wouldn't register a touch at all sometimes when trying to unlock the device.

Running iOS 8.1 on a 6 Plus.

Anyone else getting the same issue?

Thanks
 
I have seen this issue since the 5S and in fact not just with Touch ID but also with any screen gesture. However, I only experience the problem if the phone is on a work surface which charging and I am using one hand to operate it. If I pick the phone up in my left hand and operate with right hand it all works normally.
 
I have a lot of electrical noise in my shop and the screen can really not work hardly at all when one tool is running. the 6+ is better then my 5s was.
 
I have had no problem. Just tried it 3X while on dining room table. Haven't noticed it before either. As long as I place finger correctly on button.
 
I've notced this as well. Works flawlessly when not being charged though. Definitely a SW bug because the 6 I had before my 6+ did the same thing.

(Using the standard Apple 5W plug & lightning cable)

Are you using a third-party charger? I noticed that when I was using a third-party charger in my car (my car has several standard 2-prong outlets), TouchID would only work intermittently. As soon as I switched to an Apple charger, I never had another issue (I could turn the issue "on and off" by switching back and forth between the non-Apple and Apple charger).

I noticed this as well on my i6. I'm using the charger that came with the phone. When not charging, the Touch ID works flawlessly.

Yes, I'm using a third-party cable (a cheap one off eBay). But it seems others are also experiencing the same issue with the genuine Apple Lightning cable as well. :confused:

The problem doesn't occur all the time when on charge but definitely only occurs when it is on the charger.

TouchID works 99% of the time for me when it's not connected to a charger and the Home button is 100% clean and smudge free when I'm using it. So it's definitely not down to a faulty or dirty home button/TouchID sensor on my device.
 
In addition to my 6+ and the 6 I had before it, my gf's 6 also has less responsive Touch ID when charging. It's gotta be a SW bug

Definitely much better with Apple charger and certified lightning cable, but still somewhat less responsive. I even get phantom touches sometimes on my iPodT5. All my Android devices have always had similar issues.
