Apple investigates iPhone 6s battery bug

The bug displays inaccurate battery percentage on phones, possibly due to time zone changes.

The iPhone 6s and iPhone 6s Plus may be affected by a bug which displays an incorrect battery percentage.

Some users have reported their phones as stuck on displaying a certain percentage, which may lead them to believe it's more charged than it actually is.

Many users have vented their frustration on Apple Support Community forums, with one user JonBonn claiming their iPhone may report an 87pc charge all day, and still display the same amount despite being plugged in charging for an hour.

"The only fix I've found is to power the phone off and then turn it back on. Then the percentage will update correctly, and will usually continue to update properly for awhile. But eventually it gets stuck again," they wrote. "In the three days since it was delivered on Friday, I've had to reboot my iPhone 6s Plus at least four times to fix this issue."

The bug may occur when you manually change your iPhone's time zone, or as the time zone changes automatically as you travel between countries. This can lead to the battery percentage not updating, meaning it's likely to display a higher level of charge than in actuality.

Apple recommends users restart their phone and go to Settings > General > Date & Time to check the handset's clock is setting itself automatically. The company said it was aware of the issue, and was investigating the cause and a solution.

The iPhone 6s and 6s Plus use built-in rechargeable lithium-ion batteries and one of two chips created by Samsung and TSMC.

Shortly after the phones' release in September last year, it was reported the battery life of a model varied depending on which of the two processors was used in production.

Apple denied the claims, saying the tests put the models under an unlikely amount of strain, and that battery percentage between the two types of phone should only differ by up to 3 per cent.
