APPLE users have claimed the latest version of the iPhone operating system has played havoc with the battery in their device.

On the tech giant’s support firm, users have claimed the battery indicator hits 30% before slumping to zero and shutting down the phone

The disgruntled Apple lovers claim they were clobbered after downloading iOS 10.1.

One user wrote: " It jumps from 30% charge to 1% in a few seconds then shuts down.

"As soon as it reboots after connecting to a charger it show 30% charge.

"When I unplug it right away it still shows 30% and runs like nothing happened for a good few hours.

"So it goes from zero charge to 30% in the time it takes to reboot? Strange."

He also suffered problems when starting his phone up in the morning.

"Shutting the phone down at night with a good 80% charge, it won't reboot in the morning due to no battery charge.

"I plug it in and its back to 30% in a few seconds."
