The iPhone 13 may support faster-charging speeds with a 25W power adapter, compared to the current limitation of the iPhone 12, which only supports fast charging at up to 20W, according to a rumor originating from China.
The iPhone 12 supports fast charging with a 20W or higher power adapter; however, even if users use a more powerful wall adapter, the iPhone itself only supports up to 20W. According to the rumor, Apple will provide users with support for a 25W power adapter this fall, and with it, it will release its own 25W power adapter as an accessory for purchase. Apple's current 20W power adapter retails for $19.99.
Compared to 20W, 25W won't bring a drastic change to charging speeds or typical day-to-day charging for users. Many flagship Android smartphones, such as the Samsung Galaxy S21, already support 25W. Support for the faster-charging speeds will come alongside increased battery capacities for each of the iPhone 13 models, which will come in handy on the higher-end variants due to more advanced displays.
The iPhone 13 Pro and iPhone 13 Pro Max are expected to benefit from LTPO displays, which will not only provide users with a better viewing experience with ProMotion 120Hz refresh rate but may support always-on functionality.
