Some users have been experiencing the issue

Last fall, iPhone 6, 6s, 6 Plus and 6s Plus users started complaining about an issue with their phones that caused the devices to suddenly shut down for seemingly no reason at all. Apple says that it has successfully fixed the issue in the latest 10.2.1 update, which was released last month.

The issue forced users to plug smartphones into an outlet in order to get them to power back on. Apple has been working on fixing the issue for quite some time now and some reports even said that the company could start a recall for such iPhone models.

It seems that Apple managed to fix the issue on more than 80% of iPhone 6s and over 70% of iPhone 6 smartphones.

In a statement to TechCrunch, the company said, “With iOS 10.2.1, Apple made improvements to reduce occurrences of unexpected shutdowns that a small number of users were experiencing with their iPhone. iOS 10.2.1 already has over 50% of active iOS devices upgraded and the diagnostic data we’ve received from upgraders shows that for this small percentage of users experiencing the issue, we’re seeing a more than 80% reduction in iPhone 6s and over 70% reduction on iPhone 6 of devices unexpectedly shutting down.”

The issue doesn’t plague iPhone 7 and iPhone 7 Plus phones

However, Apple isn’t confident that it solved the issue for all iPhone 6 users, and has thus added the ability for the device to be restarted without having to connect it to a power outlet. “If a customer has any issues with their device they can contact AppleCare,” Apple added. In addition, Apple reassures users that this is not a safety issue, thus shutting down rumors of a recall.

Moreover, users who have installed the update and are still experiencing the issue can check their serial number on Apple’s website to determine if a battery replacement is necessary. Eligible users can get a replacement battery, free of charge.

The issue could be connected only to some older batteries. When the phone recorded sudden spikes of activity to the maximum power draw, it would immediately shut down. New batteries aren’t affected and it seems that the issue hasn’t been recorded with the latest iPhone 7 and iPhone 7 Plus devices.
