No Always On Display
If you were hoping that the new OLED panel on the M4 iPad Pro would have always-on capabilities, we have some bad news. Despite offering an LTPO display with a refresh rate that can go as low as 10Hz, the always-on display remains an iPhone Pro exclusive feature.
Nevertheless, the lower refresh rate of the Ultra Retina XDR display should help to preserve some battery life over the 24Hz floor of prior models.
