The 11 Pro max had thr best battery life in my opinion. I have the 15PM and it’s an ok battery.

Split screen for apps. I don’t use it a lot in Android. But it does come in handy sometimes.

Put your sim card in. Ask siri, “call my mom, dad, or spouse”. It may call their relatives and you get hold of them.

iPhone 11 Pro Max. It was one of the best batteries ever. Great cameras. Came with fast charger in the box.
