All new Iphone models this year have larger batteries than their predecessors. The biggest difference is in the Iphone 13 Pro Max, whose battery has a charge of 4,352 milliampere hours, compared to 3,687 in the Iphone 12 Pro Max.
But the phone does not charge significantly slower, and Chargerlab seems to have found the explanation, reports Appleinsider. The company’s measurements show that the Iphone 13 Pro Max charges with higher power than before. Between about 10 and 40 percent charge, the power is 27 watts, and then goes down to 23 watts. From empty to fully charged took 86 minutes
Iphone 12 Pro Max charges with a maximum of 22 watts but slows down more at the end and according to several tests it takes over two hours to charge it fully from empty.
To get 27 watts, you need a charger that can deliver 3 amps / 9 volts, which most modern chargers with a USB-c output and a maximum power of 30 watts or more can handle.
