How to Disable Battery fully charged notification iphone 6

That is not a full battery notification. If the device is vibrating during the charging cycle on a regular basis, then something is wrong with the device. Also, the device will not vibrate when the battery reaches 100%. There is not setting for that, as that function does not exist. You have something else going on that is causing this. The phone will not vibrate while charging. If it is vibrating regularly, either something is wrong with the phone, or you are getting some other type of notification. If it appears that it vibrates at 100%, again, some other type of notification.

You're welcome. You may have some issues, but the device should not light up and vibrate if Do Not Disturb is on, it would do that if just the Mute switch was on. Try restoring the device to factory, and not adding any additional content to it and test for a period of time. See if anything improves. If so, then it means there is probably a corrupt file in your backup.

The phone responds as though I just plugged it in to be charged.

That would suggest a bad connection. Make sure everything is firmly plugged in and that nothing is at funny angles. Check the charging port on the phone for lint or other debris (strong light and a magnifier are your friends). If your plugging it into a computer, that might be the problem. Try plugging it into the wall. Try a different outlet. Try a different cable. Try a different charger.
