The report comes from 9to5Mac, stating that the new MagSafe charger has a model number of A2548. This is certainly different from the A2140 model number of the current MagSafe chargers that launched with the iPhone 12 series last year.
The report claims that Apple submitted the new MagSafe charger test unit to the FCC on August 13, which is less than a month ago. Since then, the charger has been tested with various iPhone models, including iPhone 12 and four “New Phone” units, which are presumably the iPhone 13 series devices.
As per the report, FCC tested the MagSafe unit with “Legacy Phone” models with model numbers A2341, A2176, A2172, and A2342. These are essentially the model numbers of iPhone 12 units.
Now, it is worth mentioning that the new MagSafe charger does not look much different than the existing models. The report also states that Apple sometimes changes the model numbers of its products even when there is a minor change in them.
Hence, we can safely assume that the new MagSafe charger will not come with any major change. However, it might come with stronger magnets or improved charging efficiency for future iPhone models. We will get to know more about it once Apple officially launches the product at its September 14 event. So, be sure to stay tuned for more information.
