Apple will offer a dynamic 120Hz ProMotion display on the iPhone 12 Pro models with the ProMotion system, the display on the “Pro” models will switch between 60Hz and 120Hz depending on the content. This is done to save battery life although Apple is planning on increasing battery capacity some more for this year’s models.
Also Apple going to introduce the 5G in iPhone. The combination of 5G and ProMotion is going to require more battery power and Apple is expected to pack the iPhone 12 Pro Max with a 4400mAh battery
