Unable to activate Touch ID on iPhone

My Touch ID is not working on my Iphone 6s, I did everything suggested on the net how to resolve it but to no avail. I tried several forced power of and restart but still the prompt out message "unable to activate touch id on this phone" come out. My ios is updated to 10.2. Also noticed that my 100% battery is fast to drain than to my usual usage. I need an immediate reply from this problem as it make me unease on this regard. I searched for an answer but i read thousands of complaints but has no confirmed solution. Does Apple did some action to this? Are waiting to come up this problem to international television? Do a reliable answer as soon as possible.

Hello DAD29,
Thank you for using Apple Support Communities.

I understand from your post that the Touch ID on your iPhone 6s is showing an error message saying "unable to activate Touch ID on this phone" and your battery is draining quicker than it normally does. I know how important it is for your Touch ID to be working properly for you and for your battery to last throughout the day. Please follow the steps below to address your Touch ID issue.

Use Touch ID on iPhone and iPad

Make sure that you have the latest version of iOS.

Make sure that your fingers and the Home button are clean and dry.1 For the Home button, use a clean, lint-free cloth to wipe off any dirt or debris.

Your finger should cover the Home button completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.

If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring.

Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and that you've enrolled one or more fingerprints.

Try enrolling a different finger.

If you can't enroll any of your fingers, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support.

Regarding your battery depleting faster than normal, I recommend checking the battery usage and using the tips in the following articles:

Best Regards.
