Q: Battery charge indicator stuck on 100%

Answered here: Battery charge indicator stuck on 100%

Hi there,

You can hold the home button and lock button down simultaneously for about 10 seconds until the Apple logo apperas.

Hope this helps,

If it is an iPhone 6S, Apple has a fix for this problem (IOS 9.3) which is currently in beta. Should be released in a few weeks.

For those who didn't bother to click the link:

This issue can occur on the iPhone 6S or iPhone 6S Plus if you've manually changed the time on the device or changed time zones while traveling. Apple is aware of this issue and will fix on a later OS update. In the meantime, here's the fix:

Restart the device. From the Home Screen, tap Settings > General > Tap Date & Time. Ensure Set Automatically is enabled
