Following up its recent iPhone 13 production revelations, Digitimes states that Apple’s new smartphone range will be up to 20% more power-efficient than the iPhone 12 models - a massive upgrade. And the site also reveals the primary reason for that power saving: next-generation displays.

Digitimes states Apple partners Samsung Display and LG Display are currently converting their iPhone production lines from LTPS OLED, used in the iPhone 12 range, to LTPO OLED. This “completed in the first half of 2021” explains Digitimes’ source. LTPO OLED displays have been rumored for some time, but this is the first time we have heard about the extent of the power saving they will help to bring.

And this is a double win for iPhone fans. First, iPhone 12 models actually have worse battery life than their predecessors after Apple equipped them with smaller batteries than the iPhone 11 range. Second, LTPO enables a variable refresh rate of between 1Hz and 120Hz so iPhone users are finally going to enjoy the high refresh rates that have proved popular on Android devices for the last few years - but without the excessive battery drain it had caused. Apple is expected to market this high refresh rate as ‘ProMotion’, something it introduced on iPad Pros several years ago though they are still using LCD panels.

And there are further reasons to be excited about the battery life of the iPhone 13 line-up. Alongside LTPO displays, they will have more efficient next-gen 5G modems and the company’s A15 chip, which will bring increased performance and reduced power draw.

It isn’t all about efficiency though, iPhone 13 leaks have also revealed Apple’s plans to reduce the notch (at last!), boost WiFi speed and range, overhaul the camera experience and introduce an improved version of MagSafe.

Combine all this with the aforementioned earlier release date and a good year for Apple looks set to become a great one. But they do need to fix one serious problem first.
