According to multiple iPhone users, a recent software update has caused glitches and errors making the phone unusable for some.

Following an update to IOS 10.1.1, users reported excessive battery drain via Apple’s official website, with some phones shutting off unexpectedly when the battery life dropped to 30%.

One user Mjolcresure claimed, “It [the battery life] jumps from 30% charge to 1% in a few seconds then shuts down. Now here is the stranger part. 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.”

The issue seems to persist across all iPhones, even the newer iPhone 7 model. Another user claimed, “Interestingly I also identified this problem on my iPhone 7, and it only has 7 days of use, unfortunately I’m already having a bad experience with the new iPhone 7, although the problem is only iOS 10.1.1 should fix this urgently.”

Others have reported that the standard Apple Earpods that come bundled with each iPhone no longer work following the update. The current Apple support forum topic runs eleven pages long at the time of this writing, but Apple has not issued a public statement on the reports or provided a fix for users. The staff of Apple’s Genius bar — the help and repair desk in Apple stores — have reported an unusual discharging of phone batteries.

The Daily Mail Australia reports that Apple has stated that the issue has only affected a “relatively small batch” of iPhones but did not say how many devices were affected. They did state that they would replace the battery in all affected handsets.

This is the second iPhone error that Apple has had to deal with recently, as many iPhone users reported an error called “touch disease” that caused a grey bar to appear at the top of the screen. Apple reportedly agreed to fix the issue on devices for a repair fee of $149.
