LTPO
LTPO is a display technology that lets a screen adjust its refresh rate continuously, for example from 1 to 120 hertz. That saves battery.
What does LTPO mean?
A display with a fixed refresh rate redraws the image at the same rate all the time, even when nothing is moving. An LTPO display can lower the rate when you read a text or look at a photo, and raise it again when you scroll or play games.
The advantage is battery life: the less often the image is redrawn, the less power the display uses. That is why LTPO is mostly found in more expensive smartphones and smartwatches, where the display is meant to stay on all the time.
A general explanation of the term, not from a video. How it plays out on a specific device in everyday use is covered in the reviews below.
