PSA: Non-iPhone 12 Models Charge Super Slowly With MagSafe Charger
Apple has introduced a new model with the iPhone 12 models Mag 39 Mag Safe Charger This means that the iPhone 12 Pro can be charged at a maximum speed of 15W with the magnets on the models.
The MagSefe charger can technically be used with older iPhones, but that’s not a good idea, as charging is slower with non-iPhone 12 devices.
We did two tests with the iPhone XS Max, lowering the battery to 1 percent, putting it in the aircraft wall and charging for half an hour.
In the first test, the MagSefe charger charged the iPhone XS Max 13 percent in 30 minutes, while in the second test, the iPhone XS Max charged 14 percent in 30 minutes.
We tried so many Qi-based wireless chargers and a 7.5W Qi charging speed have not been seen to slow down. For reference, a 7.5W charger can charge the iPhone 25 percent in half an hour.
We tested the iPhone XS Max under the same conditions as the MagSefe charger with a standard 7.5W Belkin charger, which charges 26 percent in a 30 minute window.
For those who do not have an iPhone 12 ‘and intend to get a MagSefe charger to use with older iPhones, do not do so. It is not worth it for slow charging speed and you are better off with a standard Qi charger.
The MagSafe charger works well with the iPhone 12 ‘and should charge faster than the Qi, but it is not as fast as charging with a USB-C cable and a 20W power adapter by lightning. This is not surprising, since charging a USB-C charger paired with a 20W + power adapter allows for faster charging, where iPhone 12 models can charge up to 50 percent in half an hour.
