Last year, Apple brought MagSafe magnetic wireless charging to the iPhone 12 series with a maximum power of 15 watts. The whistleblower Max Weinbach said that the iPhone 13 series will use a larger coil.This may mean that wireless charging power is increased, and wireless reverse charging is also expected to be introduced.

However, the wireless reverse charging of the iPhone 13 will be limited to its own devices such as Apple Watch and AirPods.
The reason for the addition of reverse charging may be related to the general increase in battery capacity of the iPhone 13 series. According to previously exposed information, the iPhone 13 Pro Max is equipped with 4352 mAh, the iPhone 13 and iPhone 13 Pro are both 3095mAh, and the iPhone 13 mini is 2406mAh.
In addition, a comparison chart shows that the three camera openings on the back of the iPhone 13 Pro are a circle larger than that of the iPhone 12 Pro and appear denser. This should mean an increase in the aperture, an increase in the lens group, and an increase in pixels.
According to existing information, the area of bangs on the front of the iPhone 13 series has also been reduced for the first time, and the price may even be slightly lowered.
