A lot of producers have added 90Hz and 120Hz shows to smartphones — just like the Samsung Galaxy S22 Extremely or Google Pixel 7 Professional — and plenty of numbers are being thrown round (60Hz, 90Hz, 120Hz), however what do they imply? Most significantly, what’s going to they imply for the way you’ll use your smartphone?
Smartphones are getting an increasing number of highly effective, however with the final technology’s {hardware} nonetheless holding its personal, the soar from technology to technology doesn’t appear as nice because it as soon as did. The place are producers to go when a brand new cellphone doesn’t really feel extra highly effective than final yr’s gadget? One different is to make it really feel smoother and extra responsive — and an effective way to do this is to extend the refresh fee of its show.
Should you don’t know why it’s best to get excited a few 120Hz show, then this information is for you. We’re going to interrupt down what a rise in refresh fee is, the way it will profit your smartphone in the long term, and what precisely the adaptive refresh fee on the iPhone 14 Professional actually is.
What’s refresh fee?
Earlier than we will clarify how a 90Hz or 120Hz show will profit you, we have to unravel precisely what refresh fee is, and to do this, we have to know the way shows work. There’s quite a lot of technical stuff concerned right here, however at its most simple stage, a show works by exhibiting you a sequence of photos, or “frames.” To make a video, shows want to indicate a sequence of frames, one after one other. The refresh fee of a monitor is what number of instances a picture is up to date per second. So a 60Hz show refreshes its picture 60 instances a second. That is clearly too quick to your mind to trace, so it’s tricked into considering it’s watching a shifting picture fairly than a sequence of single frames.
The next refresh fee means extra photos are proven in the identical period of time, which implies any motion between every body appears smoother. As a result of there are extra frames, it reduces the hole between particular person frames. Whereas not one thing you’re more likely to consciously discover, most individuals can really feel some distinction between refresh charges. Additionally, extra photos imply adjustments resolve faster — so your cellphone will really feel extra responsive, because it appears to react extra rapidly to your instructions.
It sounds much like your graphic processor’s body fee, and that’s as a result of it’s. Body fee is measured in frames-per-second, or fps, and that’s how rapidly a graphics processor can course of and ship particular person photos to your show. You’ll want a monitor with a refresh fee of a minimum of 120Hz to show 120 fps at its best. Nevertheless, whereas refresh fee is much like fps, it’s not the identical factor. Refresh fee is tied to the monitor itself, whereas the body fee is how rapidly data is distributed to your monitor by your graphics processor.
What distinction will you discover between 60Hz, 90Hz, and 120Hz?
We’ve already lined this within the final part, but it surely’s value mentioning once more that a rise in smoothness and responsiveness are the first advantages you’ll get from an elevated refresh fee. Scrolling via your apps and swiping throughout menus will really feel smoother and extra responsive on account of the upper refresh fee. Movement blur — the blur you see between actions — may even be lowered on account of the upper refresh fee.
However the next refresh fee isn’t nearly day-to-day usability. Gaming efficiency is without doubt one of the greatest beneficiaries of a better refresh fee, and it’s because of this gaming telephones led the cost on larger refresh charges. Telephones just like the Razer Cellphone 2 and the Asus ROG Cellphone 2 have been amongst the primary to pack larger refresh charges than regular for a purpose, and it’s as a result of a show with the next refresh fee additionally has decrease enter lag. Enter lag is the time between an motion being triggered on the show and it going down within the recreation. An ordinary 60Hz show can’t have an enter lag quicker than 16.63 milliseconds as a result of that’s how lengthy it takes for every picture to refresh, whereas a 120Hz show can attain 8.33 milliseconds, because it refreshes twice as usually.
Should you’re actually unsure whether or not you’ll see the profit from utilizing a tool with a 90Hz or 120Hz show, we suggest heading out to a service or producer retailer and making an attempt out the cellphone or pill for your self. With regards to refresh fee will increase, the proof is actually within the pudding, and there’s no strategy to clarify the distinction it makes with out making an attempt it for your self.

The choice to disable larger refresh charges is offered on most telephones with refresh charges larger than 60Hz, and it was significantly helpful on the Google Pixel 4, the place an already small battery was severely hampered by the 90Hz refresh fee.
Outdoors of taxing the battery, the next refresh fee is simply costly total. It’s nonetheless comparatively new tech on smartphones, which implies it’s more likely to be restricted to flagship gadgets just for the following few years or so. Outdoors of specialised gadgets like gaming telephones, don’t anticipate to see this on finances or midrange telephones in the interim.
What’s an adaptive refresh fee?
Samsung’s Galaxy S21 vary didn’t simply introduce a brand new design, it additionally debuted a model new function for smartphones — show tech with an adaptive refresh fee. Since then, we’ve seen the expertise unfold to different flagship telephones, together with Apple’s iPhone vary and the Google Pixel telephones. However what does it imply?
In fundamental phrases, the cellphone is ready to change the refresh fee to match your actions on display. Should you’re taking a look at a nonetheless picture, it’ll pull the refresh fee down, as there’s much less must refresh the picture each second. Or, for those who’re enjoying a fast-paced recreation, it’ll ratchet the refresh fee up so you may get the very best expertise.
Why is that this a function you need to be enthusiastic about? Altering between refresh charges usually requires diving into your Settings menu, however any time you’re taking a look at a nonetheless picture, you’re not likely getting the advantage of the additional frames. Nevertheless, it’ll nonetheless be pulling additional energy out of your battery, so giving your cellphone the flexibility to intelligently acknowledge when the next refresh fee isn’t wanted helps to maintain battery consumption down.
The refresh charges on provide rely on the mannequin you’re utilizing. The Samsung Galaxy S21 and S21 Plus may entry refresh charges between 48Hz and 120Hz, whereas the Galaxy S21 Extremely may change wherever between 10Hz and 120Hz. The broader refresh fee vary means the S21 Extremely can push the refresh fee even additional down when it’s not wanted, saving much more battery. Fortunately, nowadays, most telephones that supply this capability have a tendency to supply charges between 1Hz and 120Hz.
Do you want a 90Hz or 120Hz refresh fee?
Completely not — a lot in the identical method you don’t “want” a digital camera, flashlight, or pinball recreation in your smartphone. However anybody who has used a tool with a 90Hz or 120Hz refresh fee will inform you the huge distinction it makes to the way in which your gadget feels.
