A new claim, reported by Cult of Mac, is that Apple will use LTPO (low-temperature polycrystalline oxide) screen tech in next year's iPhone models.
LTPO displays are already used in the Apple Watch Series 4 and Series 5, and are significantly more energy-efficient than OLED displays. They can improve battery life by up to 15 percent over OLED, something which would be hugely appreciated by phone buyers.
But is the theory correct? We've heard this one before: similar rumours did the rounds in both 2018 and 2019. Hopefully it's a case of third time lucky.
It's since been proposed that the LTPO screens will be supplied by LG and Samsung.
LTPO screens should also most it possible for the 2021 iPhone to have an always-on screen. More here: iPhone 13 'will have always on screen'
