There’s numerous confusion surrounding the Galaxy S22 sequence and the refresh charges in their shows. We are within the means of reviewing the S22+ and S22 Extremely and sought after to proportion our revel in to check out and transparent what Samsung’s PR could not.
Let’s get started with the reputable claims. The Samsung Galaxy S22 Extremely show has a variable refresh price going from 1Hz to 120Hz. The Galaxy S22 and S22+ handiest duvet the 48-120 Hz vary. That is the newest commentary from the corporate, after first of all publishing other numbers. The issue is that whilst the unique numbers were not totally right kind, the brand new ones are not both.
Earlier than we pass on, we must make the respect between refresh price and body price. They’re frequently tied in combination, however they do not have to be – particularly at the S22 telephones. Body price refers to how frequently the GPU attracts a brand new symbol. Refresh price is how frequently the show {hardware} if truth be told takes that symbol and presentations it to you.
We checked the Android 12 strengthen API’s at the Galaxy S22+ and S22 Extremely and located that their panels can refresh on the following charges: 10Hz, 24Hz, 30Hz, 48Hz, 60Hz, 96Hz and 120Hz. On the other hand, after days of trying out, we by no means if truth be told noticed the the S22+ run at 10Hz. We did see it run at 24Hz, then again. Sure, 24Hz, not up to what Samsung formally advertises. As for the Extremely and why it does not record 1Hz, we’re going to get to that later.
Supported refresh price modes • GPU Watch
The real body price at which the UI is rendered is expounded however now not the similar because the numbers quoted above. With the intention to observe that, Samsung has incorporated a nifty device within the Developer menu known as GPU Watch, which exposes an overlay for what the Android SurfaceFlinger is outputting to the graphical buffer. In different phrases, that is an fps counter, relatively than a refresh price environment for the show.
We did if truth be told see the S22+ UI drop to one fps when appearing a static symbol. The real refresh price of the shows was once upper, normally 24Hz. “Normally”, however now not at all times because the refresh price adapts to what’s lately operating at the telephone and whether or not you’re interacting with it.
24Hz at idle within the UI
In our trying out we found out that the S22+ does a perfect activity of managing the refresh price of its show. The fundamental common sense is that each time you engage with the show whatsoever, the refresh price in an instant shoots as much as 120Hz for the most efficient conceivable responsiveness. Whilst you depart the telephone by myself, the refresh price virtually in an instant drops to an appropriate mode to deal with the fps of what’s taking place on show.
The bottom refresh price the show reaches whilst idling on a static symbol is 24Hz. On the identical time readings from the Android SurfaceFlinger have been as little as 1 fps. This permits the GPU to sleep as a rule, lowering energy utilization, although the show refreshes extra ceaselessly than vital.
Past that, the telephone’s tool does an overly respectable activity of matching show refresh price to the body price of what’s going on on show. Static pictures are proven at 24Hz (say, sitting at the house show without a consumer interplay). If there may be an app if truth be told operating, that quantity is maximum frequently 60Hz to deal with motion.
24Hz or 60Hz in maximum apps as soon as left idle
Whilst this typically works neatly, we discovered that the automated detection does not at all times take advantage of logical possible choices. This was once maximum frequently seen in internet browsers (pre-installed and third-party), which we could not reliably get to paintings at 120Hz. The entire ones we attempted dropped right down to 60Hz whilst now not touching the show. That is simply testable via operating the very good UFO take a look at via BlurBusters.
Browsers idling at 60Hz
On the other hand, we will be able to’t call to mind many exact sensible situations the place the browser could be appearing one thing at upper than 60 fps with out you interacting with the show, so Samsung would possibly have if truth be told made the best selection.
Refresh price dealing with whilst enjoying video is especially nifty and has a tendency to observe the fps of the video this is being performed. Play a 24 fps clip and the S22+ makes sense sufficient to run its show at 24Hz. 30 fps ends up in 30Hz and 60 fps does 60Hz, you get the purpose. We handiest hardly controlled to commute up this common sense, it really works impressively neatly.
Show refresh price following video fps
Higher nonetheless, we verified that this conduct is provide and dealing simply as neatly now not handiest with native video playback but additionally whilst streaming video from the likes of YouTube or Netflix.

Does all of this imply that the Galaxy S22 Extremely and its LTPO 2.0 show haven’t any exact merit over the LTPS shows of the S22 and S22+? Neatly, now not relatively – we discovered one use case the place the 2 show sorts behave very otherwise and it pertains to HDR video playback.
As soon as the show enters “HDR mode”, the Galaxy S22+ show locks its refresh price to 120Hz without reference to the body price of the HDR content material being performed. This isn’t ideally suited with regards to battery financial savings, however is appears to be a limitation of the {hardware} relatively than tool.
HDR playback pins the S22+ show refresh price to 120Hz • SDR video at 24 fps
We are saying that since the Galaxy S22 Extremely does take care of its refresh price switching common sense all the way through HDR playback, most likely due to its LTPO 2.0 tech. This, then again, is a case of the S22 Extremely excelling at what it does, relatively than a deficiency to characteristic to the S22+. And to be transparent, SDR photos does permit the S22+ show to compare its refresh price to the video body price.
However the benefit of the Galaxy S22 Extremely isn’t as giant as we in the beginning concept. We by no means if truth be told noticed the telephone drop to 1Hz – or certainly underneath 24Hz. All the way through all of our trying out up to now, each the Galaxy S22+ and S22 Extremely confirmed 24Hz to be their lowest refresh price.
In any case, we attempted a couple of video games we all know can render at over 60 fps. Those all labored as anticipated with the Galaxy S22+ switching its show to 120Hz to get the very best fps quantity conceivable.
Video games making essentially the most out of the 120Hz refresh price
Because of Samsung’s new GPU Watch overlay, we will be able to now get what’s successfully an in-game fps counter or no less than an in depth approximation to turn out that the video games are certainly operating at over 60 fps. Up to now we needed to depend on a visible estimate.
This is an reputable commentary from Samsung at the S22 refresh price scenario.
The Samsung Galaxy S22+ handles prime refresh price and adaptive refresh price just about completely according to the real content material this is being displayed and the consumer’s wishes. Show refresh price can now drop even decrease. Samsung created some unlucky commotion with its advertising, however but even so that, we will be able to handiest reward what we’re seeing right here.
We must word that that is how the Galaxy S22+ and S22 Extremely behave with their present tool. Issues would possibly alternate sooner or later. We are specifically curious to peer if that 10Hz mode reported via the S22+ is if truth be told enabled (or if its will get got rid of from the record). The similar is going for the S22 Extremely’s decrease certain – can we ever if truth be told see 1Hz?
Be expecting our detailed critiques of the Galaxy S22 flagships quickly with extra data on their shows and the whole lot else too.
