Adaptive refresh rates first became mainstream with the emergence of 120Hz panels. Locking the refresh rate at 120Hz can get quite power-demanding, so manufacturers figured they’d be better off limiting the panel to 60Hz for certain activities like watching videos. LTPO displays thereafter helped reduce battery consumption further, taking down the minimum refresh rate to as low as 1Hz.
But while the S22 Ultra does make use of the fancy piece of tech, the S22+ and S22 gave a miss. Both non-ultra models bottom out at 48Hz instead. Now, this would have been forgivable since the duo isn’t exactly top of the line, but as it stands, Samsung had earlier wrongly listed that their refresh rates go from 120Hz to 10Hz.
The company has since updated the spec sheets of the Galaxy S22 and S22+, increasing the refresh rate floor from 10Hz to 48Hz, as pointed out by Ross Young, CEO of Display Supply Chain Consultants.
All this obviously raises several questions, and Samsung has now tried to provide an explanation with a statement to Android Police.
Samsung has clarified that “the display component of both devices support between 48 to 120Hz.” This means that neither the S22 nor the S22+ feature LTPO panels. However, the 10Hz number still holds significance since that’s the rate at which data is fed to the display, using some “proprietary technology.”
Confused? In short, it means that the pipeline tells the display what to update at 10 times a second, but the display itself will still refresh at 48Hz.
“The display refresh rate was originally listed between 10 and 120Hz (10 to 120 frames per second), and we later opted to update how we communicate this specification in order to be in line with the more widely-recognized industry standard. Consumers can be assured there has been no change of hardware specifications, and both devices support up to 120Hz for super smooth scrolling,” Samsung adds.
Another department where Samsung kind of fell short was the charging on the Galaxy S22 Ultra. The 45W fast charging solution on the device was found to be barely any faster than charging via a 25W brick.
