Having already put forward the prediction that Apple will bring two-way wireless charging to the iPhone 11 , trusted analyst Ming-Chi Kuo has released a supply chain report stating that the feature will be aided by the use of a larger battery in the upcoming devices.

As reported by Apple Insider , Kuo believes that a 5.8-inch successor to the iPhone XS will receive a 20-25% increase in battery size to accommodate the power sharing feature, while the battery in 2019's 6.5-inch iPhone XS Max replacement could be around 10-15% larger than last year's model.

It's believed that a thinner OLED screen laminate will allow for extra battery space without adding to the overall thickness of the new handsets.

Additionally, Kuo also states that a 6.1-inch model (likely an updated version of the LCD-sporting iPhone XR ) will only get a small battery boost of 5% or less.
