The USB-C is probably the "best" in the consumer world. But the cables are just as likely to wear out and quit charging as any of the other profiles.
Before spending a fuck-ton of $$ on a new phone, try a new cable and a new wall wart. While your new phone will come with these, it never hurts to have a dependable spare charger set up.
I have had good luck using Samsung and Sony devices in the past. I am due to upgrade as well, so I will have to do a bunch more looking before I leap to a new cell system.
Try replacing your charging equipment as you consider spending lots of money on a completely new system.
I just want USB-C again because I can't be bothered getting an all new charging setup. I've got a 3 year old Nokia 8. Not sure what's happening but the charging connector inside the phone has gone all loose, so the cable won't sit snug in the hole and the connectors aren't 'connecting'. I can usually hack fix it by sticking a thin layer of sticky tape around the end of the charging cable but even that's not working anymore. I got a new charging cable last week and it's still the same.
Can the charging connector inside the phone be replaced? And would it even be worth it? The repair might be more expensive than the phone is worth at this point.
I have to use one of those two-factor authenticator apps to get into the system we use at work so I need to get something sorted ASAP.
Charging connectors can be replaced - next to cracked screens, I believe they are the most common repairs done on phones. Having said that, the job could still cost you a lot of money because they want you to buy a new one, but around here there are a lot of small shops specialising in fixing mobile phones. I imagine the same to be true where you are.
You can do it yourself if you have the motor skills and patience, though - there are plenty of instructions on the web, and the ports themselves are usually dirt cheap.
USB-C is pretty much everywhere now, and most phones use it, as far as I know.
