My old i3 clone came with a 1mm steel rod I use in these situations. Leave the extruder on your printer, cut the filament off, heat up the extruder to a normal printing temp, and push the gunk through the nozzle. If you have a cold side clog you’re probably going to have to add heat from something like a heat gun.
Odds are your phone has a modern connector so this isn’t necessary. I replaced my pixel 3a, which I bought in September 2019, last December. Thanks to wired phone projection, I cycled its USB-C connector twice a day for 5 years and 3 months. That’s ~4,000 cycles. The connector specification calls for a 10,000 cycle lifetime.
I did have to de-lint the connector from time to time, but other than that I had no issues.
Not to say that you shouldn’t use inductive charging of course :)
