Why does my Apple Watch not turn on unless connected to power when it has over 50% battery

I have recently bought an Apple Watch Series 3 and when the battery falls to around 55% it will turn off and not turn back on until plugged into power. When I try to turn it back on it displays the apple logo for 10-20 seconds and then turns back off. This also happens when the Apple Watch is not paired to any phone and is asking to bring it near an Iphone.


My Iphone is fully up to date.

I have tried unpairing and repairing the Apple Watch and setting it up as a new watch.

I have tried restarting both of the devices and turning on the Iphone first.


Any help would be greatly appreciated.


Many thanks,

Hamish

Hi hamisha2003,


You've completed some great steps to help try and get to the root cause of the issue. You can find additional helpful information here: If your Apple Watch won't charge or it won't turn on - Apple Support


However, as you've already updated and paired the Apple Watch you can check the battery health and optimized charging settings with the steps below found here: About Optimized Battery Charging on your Apple Watch - Apple Support


"If you want to turn off Optimized Battery Charging:
