NOTE: If the mobile device is not placed at the center of the wireless charger (Qi), charger performance will be less than
expected.
The wireless charger (Qi) is not compatible with MagSafe (introduced on iPhone 12 and later phones) and if the mobile
device is not placed at the center of the wireless charger (Qi), charger performance will be less than expected.
NOTE: About MagSafe
MagSafe is the charging system using magnetic alignment device introduced on iPhone 12 and later phones.
Not only on Mazda vehicles, on wireless chargers not compatible with MagSafe, proper area for the best charger
performance is limited depending on user environment, such as a case, position of the mobile device, remaining battery
and/or device temperature.
Regarding the wireless charger (Qi) mentioned on this Service Information, charging performance of a MagSafe
compatible mobile device is not expected to be improved.
Theory of operation of the wireless charger (Qi)
The wireless charger (Qi) transfers power between coils integrated in the charger and the mobile device.
The center of both coils should be well aligned for the best performance. Poor alignment between both coils results in
poor charging performance. Therefore, place the mobile device so that the center of the coil of the charger and the
mobile device are aligned.

Well aligned coils for best performance

Poor alignment causes reduced power reception

Effect of MagSafe to the charging performance
MagSafe is a wireless power transfer standard developed by Apple Inc. The MagSafe compatible charger and the mobile
device (iPhone 12 and later) are aligned using magnets integrated in both of them for efficient charging performance.
If only the mobile device is MagSafe compatible on a charger that is not MagSafe compatible, alignment using magnets
is not possible and the magnets and coil may interfere with the charging (see image below/left).
In this case, alignment procedure not using the magnet can reduce the negative effect on charging performance (see
image below/right).
Even for the MagSafe compatible mobile device, place it on the charger manually aligning the center of the coils.
