What’s the secret that allows the Apple Watch to have its always-on display to show Series 5 information all the time? That your panel consumes a minimum of energy. How do you get this? Reduce its refresh rate and brightness to a tolerable level to continue to guarantee enough battery life for the whole day.
In the case of the Apple Watch, it’s something many already appreciate. And now the next challenge as we read Ross Young’s Twitter
1fps the key challenge for always-on display on iPhone 14 Pro
The iPhone 13 Pro and its screens have already brought an important novelty: the ProMotion. Thanks to this we can enjoy a variable frequency up to 120 Hz, and this is very noticeable in the fluidity of the interface. But that same variable frequency means that in some cases the frequency drops to 10Hz, saving us battery life.
However, to have an always-on screen, you need to have frequencies as low as 1 Hz. That is to say a single image per second. This is what saves enough to be able to have the screen on all the time, and this is the reason why the iPhone 13 does not yet have this function.
I can’t confirm, but I expect it.

But Ross Young revealed in his last tweet that he hopes (although he can’t be sure) that the iPhone 14 Pro displays will have that minimum 1Hz refresh rate in order to make room for this feature. always on screen. Yes this could be the main attraction of the iPhone 14 Pro encourage the market to renew its terminal.
For the moment, it should continue to qualify it as possible, not probable. With rumors you never know, and the global logistical situation may cause last minute changes. We’ll find out all in September, when we should see both the iPhone 14 and the Apple Watch Series 8.
