Apple 7 Watch Charging Issue

I have the Apple 7 Nike watch. It will only charge using the USB-C charging cable that came with the watch. Are the older charging cables not compatible with the Apple Watch 7? (USB-A charger)


WatchOS 8.3

Model MKJL3LL/A




Apple Watch Series 7

Is the previous charger an original Apple Charger or a 3rd party aftermarket charger. Many aftermarket chargers were not MFI certified. They may have worked with previous watches, but WatchOS 8.3 may have rendered non-MFI chargers unable to be used. If I purchase an aftermarket charger for any Apple device I own, I always ensure they are MFI Certified. They will always work. But if companies "stole" the codes without certifying their devices, Apple can release an update, which will render those devices non-functioning. And it seems WatchOS 8.3 did this for non-MFI Certified chargers.

If you have the old charging cable and power adapter from a previous watch, it should work although you will lose the fast charging feature. Since I charge mine overnight, every night that feature is not that important to me. BTW, I have heard that some people are having problems charging the watch with third-party adapters after the 8.3 update.

Thank you for replying. Unfortunately, I have tried to use a charging cable and power adapter from a previous watch but it doesn't charge which is why I made this post. It will only work with USB-C charging cable that came with the watch.

It looks like watchOS 8.4 was just released, and the bug fix summary shows: " watchOS 8.4 includes bug fixes and important security updates, including: Some chargers may not work as expected."


So while we never saw anything official about this published by Apple until now, we know they really did introduce a problem in watchOS 8.3.


Hope this fixes it for everybody!

Didn't work for me. Watch OS 8.3 was definitely the culprit because it stopped accepting the old original charger after the update. However OS 8.4 didn't solve the problem. I find Apple not sincere in trying to save the environment. They change from USB B to UCB C and stop supplying the plug. I have to buy it anyway coz all my other plugs from Apple are USB B! Since my watch came via the post, I've to make an extra trip to town just to get it. 😡

leaping, in the modern world these days, you are more the "exception than the rule." Yes, if you have absolutely no way to charge an Apple Watch, meaning you're not one of the millions upon millions who already owned an Apple Watch and had full access to a previous charger, which would certainly charge your new watch, or you don't own a modern computer which has a USB C input as most have had for the last few years, or you don't own any other product which is USB C, which has become the norm in electronics for the last few years, then yes, for YOU, it's an inconvenience.


To suggest however, because you have not yet experienced USB C, does not make Apple's quest for less electronic waste insincere.
