According to the prolific technology leaker DylanDKT, only the Pro models of iPhone 13 will be equipped with LiDAR sensors "due to one reason or another".

LiDAR is used to provide accurate measurements, quicker autofocus and more realistic AR experiences.

The claim goes against previous rumours that the sensors would be used in all four models of iPhone 13. But it shouldn't be discounted on that basis alone: DylanDKT has made some accurate calls in the past and currently has an accuracy rating of 81.3% on the pundit monitoring site AppleTrack.

There are currently LiDAR sensors in the iPhone 12 Pro, iPhone 12 Pro Max and iPad Pro, but most pundits believe it is only a matter of time before they are found in a wider range of Apple products. DylanDKT's tweet appears to imply that the rollout of LiDAR on non-Pro iPhones has only been postponed rather than cancelled, however, and we can probably expect it to happen in 2022.

The sensors are likely to be manufactured by Sony, as the company has signed a contract with Apple that runs until 2023.
