Apple’s ‘Hi, Speed’ event kicks off tomorrow, on October 13 and we’ll likely be greeted by a total of four new iPhone 12 models. While there might still be some confusion regarding the specifications of each handset, it’s pretty much confirmed that no iPhone 12 model will get a 120Hz OLED screen but it’s not because it didn’t have the supported hardware. Quite the contrary, as leakster Jon Prosser states that Apple likely wanted to market the battery life of each model, so it had a choice between a faster display and support for 5G networks. The company chose the latter, for reasons which you’ll read about in just a moment.

According to Prosser, omitting a 120Hz display was all about delivering the best battery life possible. If both 5G and 120Hz options were available and enabled, it’s highly likely future customers will complain about the battery endurance of any model they acquire. One other reason as to why Apple chose with 5G instead of a faster display is because it is easier to market. He implies that a lot of users aren’t going to worry about a faster display being present on an iPhone, probably because iOS already delivers that seamless and fluid operating system experience.
