Wireless charging can be affected by case thickness and phone alignment. It is normal for your phone to become slightly warm during wireless charging. The backplate of Anker Magnetic Phone Case is 2.6 mm thick.

If your charger requires a case no thicker than 2.5 mm, or if a non-magnetic charger is not properly aligned with your phone, charging efficiency may decrease and additional heat may be generated. This may activate safety protection, including foreign object detection (FOD) where applicable, and cause charging to stop.

Try the following troubleshooting steps:

1. Realign your phone. Center your phone on the charger's magnetic charging area. With a non-magnetic charger, manually center the back of your phone over the charging coil to reduce efficiency loss and excess heat caused by misalignment.

2. Test without the case. If the excess heat and error no longer occur after you remove the case, case thickness or alignment may be contributing to the issue. Switch to a magnetic charger that supports a case thickness of at least 2.6 mm.

3. Test with another charging device. Use a MagSafe-certified wireless charger or magnetic power bank that supports a case thickness of at least 2.6 mm.

4. Improve heat dissipation. Avoid charging in direct sunlight, enclosed spaces, or hot environments, such as inside a car parked in the sun. Do not attach or stack card wallets, rings, or other accessories on the back of the phone while charging. Keep the area around the back of the phone well ventilated.

5. Avoid demanding tasks while charging. Gaming, recording, videos, and navigation generate additional heat. Limit these activities while charging.
