Apple’s Health application interacts with the new iOS causing the phone to shut down with 30 per cent battery remaining and to shut off audio when using Apple Earpods. This means that users cannot listen to their U2 or Coldplay albums.

Users on an Apple forum report that the battery indicator jumps from 30 per cent to one per cent and a reboot is required so that the phone then runs for a few more hours. Another fix involves selling the phone and buying a proper one.

There are more than 11 pages of complaints about the issue on the Apple forum. Apple with its true love for customers who have paid over the odds so that they can own the brand, has ignored them completely.

To make matters worse Genius Bar staff have been diagnosing the problem as “unusual discharging of the battery.” Clearly the poor lambs have not worked out that if a reboot temporarily fixes the issue and returns the battery indicator to 30 per cent then it can’t be that .

The problem is widespread and affects all versions of iPhone that support iOS 10.x. Upgrading to the 10.2 beta does not work either.
