For those unfamiliar, the ProMotion display is the one used by Apple’s iPad Pros. This was the first time we saw a 120Hz display brought onto a tablet and mobile devices in general, and this eventually sparked a change in the mobile industry which has since seen a ton of Android handset makers follow suit.
Like we said, Apple was supposed to introduce such a display to the iPhone 12, but the rumored reason for why it was scrapped was due to battery life. As it stands, the iPhone 12s don’t exactly have the best battery life, which has been disappointing given the iPhone 11 series was actually pretty awesome in terms of battery.
It is likely Apple knew this in advance and having a 120Hz display would probably not do the iPhone 12s any favors in battery life. The report from The Elec claims that LG will be the ones helping Apple manufacture these displays, and a more recent report suggested that these displays could be LTPO and be more energy efficient.
