The real thing to watch is heat, not just speed.

Modern phones are designed to manage charging speed and slow down when needed. They do not simply take maximum power forever.
Fast charging can create more heat than slow charging, and heat can age batteries faster over time.
Use quality chargers, avoid charging under blankets or pillows, and take the case off if the phone gets hot while charging.
Fast charging is not automatically bad. Keep the phone cool and use reliable charging gear.
