Whatever tweaks Apple made to its power management system have enabled them to reduce the shutdowns heavily - but not eliminate them entirely. Brand new batteries would not be affected, but as most phone batteries run through charge cycles they get less effective (this is a well-known byproduct of lithium-ion technology and one reason everyone wants to get rid of it as soon as someone figures out something better) and more susceptible to these kinds of triggering spikes. If a customer has any issues with their device they can contact AppleCare.Īs far as I’m able to understand what happened here, Apple found that sudden spikes of activity to the maximum power draw could cause older batteries, which had some mileage on them, to deliver power in an uneven manner, which would cause an emergency shutdown of the devices. It is important to note that these unexpected shutdowns are not a safety issue, but we understand it can be an inconvenience and wanted to fix the issue as quickly as possible. We also added the ability for the phone to restart without needing to connect to power, if a user still encounters an unexpected shutdown.
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. 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. Here is the comment they provided to TechCrunch today: It’s also important to note that there was a similar but different issue that had the same unexpected shutdown symptoms late last year that resulted in a battery recall of some devices. After letting the fix simmer on customer devices, Apple now has statistics to share on how it has improved the issue, citing 80 percent reduction on iPhone 6s and 70 percent reduction on iPhone 6 devices.Ĭurrently, iPhone 7 devices are not impacted by this issue. The fix is actually already on your iPhone if you have installed iOS 10.2.1 - something that around 50 percent of iOS users have already done. Some iPhone 6, 6s, 6 Plus and 6s Plus devices could basically go dark unexpectedly, forcing a user to have to plug them into an outlet to get them to power back on.Īpple has been working on this very annoying bug and it says it has come up with a fix of sorts that should mitigate the problem on a majority of iPhone 6 and iPhone 6s devices.
Over the past couple of iPhone versions users have complained of “unexpected” shutdowns of their devices.
