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 per cent 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 per cent charge to 1 per cent in a few seconds then shuts down.

“As soon as it reboots after connecting to a charger it show 30 per cent charge.

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

“So it goes from zero charge to 30 per cent 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 per cent charge, it won’t reboot in the morning due to no battery charge.

“I plug it in and its back to 30 per cent in a few seconds.”

Another user said he was suffering from an “identical issue after upgrading to 10.1.1.”

It is not known how many people are affected by the problem and whether it is isolated or widespread.

Meanwhile a number of disgruntled Apple customers have taken to Twitter to bemoan the issue.

“I can now watch my battery literally drain as I read a text,” complained one social media user.
