Ever since I have updated to iOS 26 on my iPhone 13 Pro Max, for ref - I am using 20W adapter and lighting cable.
I have encountered issues while charging my phone, I would normally plug my phone and then it just wouldn't charge, at first I was like what the helly - maybe the port or cable is wrecked, but after test they seemed ok.
So after some trial and error I've found out that I need to disconnect lighting cable from the adapter and put it back in otherwise the phone will not charge no matter what I do lol.
I find it super funny, it's like I reconnect the adapter and cable side, but then if I remove cable from my phone right after and put it back in - not working lmao.
The thing is I'm more than satisfied with my current phone, i'm just kinda disappointed that the 'advancement' in technology is in means of downgrading older functional equipment, yep thats all I wanted to say!
