I noticed that after updating to one ui 7 I'm constantly having charging issues. I've used the same charger (cable and adaptor) and had no problems at all. I also tried using it on my buds which charges fine as well.
It just wouldn't charge at all. Then, after a few plugs/unplugs and phone restarts, it will start to work again only to stop after a few minutes then I need to unplug and plug it again.
Yes, I also used the same charger to charge my buds, which works fine. It's quite difficult to ascertain if it's the charger or the phone is buggy since it's an intermittent issue.
I actually saw some posts here that says they experienced it as well. And yes, I agree with you that in theory charging/ports should not be affected by this, but as with every update, there are risks that might cause this. But yeah who knows haha
