Avoid Charging With MagSafe

It’s no secret that wireless charging isn’t anywhere near as fast as wired charging, and that goes for MagSafe, too.
Using a MagSafe charger is convenient and helpful most of the time, but it can’t charge as quickly as a regular charging cable. MagSafe is officially rated for 15W charging, but it’s actually around half the speed of a wired 20W charger since wireless charging is much less efficient.
If you need to get a quick charge, use your regular charger instead.
If you really need or want to use MagSafe, be sure to use at least a 20W USB-C adapter and a MagSafe charger from Apple or another model that’s either MagSafe or Qi2 certified. Not all magnetic chargers are equal, and just because a wireless charger attaches magnetically to your iPhone doesn’t mean it can give you 15W charging speeds; chargers that aren’t MagSafe or Qi2-certified will be limited to really slow 7.5W charging.
