We have seen in the previous news, Apple will install the A17 chip which will be in the 3nm system; it's a big step because currently iPhone 𝟭𝟰 𝟰𝟰 are using a 5nm chip which still doesn't reach the quality of 3nm in speed and using less electricity.
According to TSMC which is a company that makes new iPhone chips, the A17 Bionic chip that will be in iPhone 1𝟱 Pro and iPhone 1𝟱 Ultra (Pro Max); it uses 35% less electricity compared to the A16 Bionic chip that is present in iPhone 11 and iPhone 11 Pro Max.

This information does not apply to normal iPhone 1𝟱 (which are not Pro) because it is possible that Apple will put the A16 Bionic chip in iPhone 1𝟱 which are not Pro as it did this year, it has not installed a new chip on normal iPhones. iPhone 1𝟰 is equipped with A15 Bionic which is the same chip as iPhone 1𝟯. And next year; iPhone 1𝟰 Pro chip will be installed on regular iPhone 1𝟱. and iPhone 11 Pro will have a new chip.
