But slow charging will preserve the battery life a lot longer, which is more important.

Wireless charging, on the other hand generates heat, which is bad for the battery.

Slow, wired charging is the best combination for battery service life. A basic 5-10W power supply when the phone is going to be plugged in overnight is a universal method to achieve that; AccA on a rooted Android device with suitable hardware allows fine-grained control in software.

Even more important is to avoid charging the battery to full. The higher the voltage, the quicker it wears out.
