Apple says iOS 10.2.1 reduced sudden iPhone shutdowns by 80%

iPhone 6S

Apple was plagued by angry customers last year for a widespread issue which caused iPhones to shut down unexpectedly. The problem appeared to affect the iPhone 6, 6 Plus, 6S, and 6S Plus units for the most part.

Victims of the bug claim that their iPhone 6 or above would switch off suddenly and could only be revived after plugging it in. Apple claims it came up with a fix to mitigate the problem and started seeding it in iOS 10.2.1, the latest version of its software. 50% of iOS users have already installed the update.

Apple says that the concern has reduced by 80% among iPhone 6S devices and 70% among iPhone 6 models. It’s also introduced a brand new ability for people who are still cursed with random shutdowns. Instead of having to rush to an outlet every time this occurs, the smartphone is supposed to restart automatically.

Apple is trying to reassure consumers that this isn’t a safety issue. However, the brand did acknowledge that it is an inconvenience and asks anyone affected to contact AppleCare. TechCrunch believes that newer iOS beta versions contain a fix which spreads the auto-restart ability to the iPhone 6 and iPhone 6 Plus.

The publication posits that Apple found sudden spikes of activity in older batteries which delivered power unevenly. This seems to have resulted in emergency shutdowns. New units likely wouldn’t fall victim to this, but almost all lithium powerhouses eventually wither down and become susceptible to such issues.

Apple may have a solution for this in the form of a new ‘your battery needs service’ message that is set to be rolled out to iOS 10.2.1 over the next couple of days. It’ll pop up in the battery info page inside Settings. The notification is supposed to appear only when the company thinks the battery really needs it.
