Apple is said to bring a number of new features and design changes with its iPhone 15 series. Adding to the list is a rumour by ChargerLab which states that the Cupertino-based company may bring 15 watt wireless fast charging on all models of iPhone 15 series. The leak, if true, will be a major change that Apple will bring. At present, wireless charging is limited to 7.5 watt. Only MagSafe accessories can reach 15 watt.
