iOS Update :10.2.1 – Random Shutdown Issue

‘Fixer’ iOS Update

You may or may not be aware that the 10.2.1 iOS update was actually released to tackle the fairly widespread issue of iPhone 6 and iPhone 6s devices randomly shutting down.

Originally this issue dictated that the phone had to be plugged in before it could restart. More than slightly annoying if you are out and about!

Apple have stated that the update has fixed the issue for ‘most’ of the devices that have been updated with iOS 10.2.1. Interestingly only half of Apple users have actually installed this iOS update to  their device.

Apparently the devices shutting down has been caused by sudden spikes in usage causing older batteries to malfunction. However when we heard this immediately started wondering whether this as it could denote that ‘older’ batteries are spread over both 6 and 6s devices.

If this is the case, then our discussion here at ArmaFone jumped to how old the batteries are that get put into new devices….we’ll have a look into that and update you should it be something we can find more information on.

iOS Update Fixes ‘Most’

Back to 10.2.1. and the other question that instantly sprung to our mind is that if the update sorts ‘most’ of the devices affected, what happens to those that it doesn’t work on?

From what we’ve seen it could be as simple as putting a new battery in the device – we’ll have to wait and find out. Again we’ll update you on this once we’ve established whether this is the case.

If you do have an iPhone 6 or iPhone 6s that has the issue of randomly shuts down and the 10.2.1 iOS update hasn’t solved the issue then let us know and we can see if we can solve the issue for you with a new battery.
