i paid a repair shop for the swapping. ($15 includes everything, battery itself is around $10 port is around $2). Whole swap took around 20 mins. though this is a third world country, so double or triple that.

but for my device, there was full repair guide available online (ifixit). the only reason I did not repair my self is because I am kinda scared doing anything battery (it was partially swollen, and i do not want lithium fire). Other major reason is I do not have screw driver bits for phone. I can do laptop repairs myself, but phone screws are even smaller, and use fancy heads, so I can not use a pointed knife’s edge to unscrew.

If your device has a ifixit guide, that would be the easiest way, they hand hold all the way through. If not, find replacement parts, see what it would cost, and maybe ask a repair shop for a price. if their quotation is within reason, then they can do a good job and you would not even need any other tools.

In fact, if I would have done it myself, I would have not repaired the port, as that required a bit more work than battery.
