If your phone isn't charging wirelessly or is charging slowly on the MagSafe charger, please check the following:

● Your phone is an iPhone with MagSafe (iPhone 12 series or later) or Samsung S24/S25.

● Use the included charging cable.

● You are using the included 33W power adapter.

● Your protective case is less than 2 mm thick.

● There are no metal accessories, credit cards, stands, or grips between your phone and the charger.

Additional information about wireless charging speeds:

● Wireless charging is generally slower than wired charging.

● Reducing the number of applications open on your phone can improve charging speed.

● High temperatures can slow charging speed and limit power output, especially during wireless charging.

● If your iPhone stops charging at 80%, it might be due to the "Optimized Battery Charging" feature. You can check and turn off this option by going to Settings > Battery > Battery Health, then turning off "Optimized Battery Charging." If you haven't enabled this feature, the issue may be related to an iOS upgrade. In that case, consider updating your software or waiting for the next system update.
