Abstract
- The obvious good thing about 120Hz smartphones is smoother movement in apps, and in a cellphone’s interface as an entire.
- Many 120Hz telephones additionally assist dynamic refresh charges, enabling always-on show capabilities, to not point out higher energy consumption.
- In video games with real-time motion, 120Hz expertise successfully breaks the ceiling on framerates — assuming your processor is highly effective sufficient to prime 60fps.
Like TVs and displays, all cellphone shows sport a specific
refresh rate
, referring to how typically they’ll replace what’s onscreen. For a very long time, most smartphones weren’t able to a refresh charge over 60Hz. The truth is, that is nonetheless true of non-Professional iPhones — when you not too long ago upgraded to a baseline
iPhone 16
or iPhone 16e, you would not essentially know that you just had been lacking something. It is not like Spotify or Google Maps are going to run agonizingly sluggish on Apple’s A18 chip.
Nowadays, nevertheless, Professionals and lots of
Android phones
now function 120Hz shows. What does that imply in follow, past the display updating twice as quick? There’s extra worth to a 120Hz panel than you may understand, which might clarify why Apple is lastly set to carry all its gadgets into the fashionable age with the
iPhone 17
lineup.

Smoother movement throughout
The obvious benefit
The very first thing anybody notices in the event that they’re used to 60Hz telephones is how a lot smoother a 120Hz machine’s interface appears. It is a troublesome factor to elucidate in writing, naturally, however every little thing feels snappier, with much less lag or blur. The impact is especially noticeable in apps with a variety of scrolling textual content or photos, akin to an internet browser or an e-book reader. Whereas a 60Hz cellphone may often appear like it is “hitching” on issues, a 120Hz cellphone seems to maintain issues intact, if not essentially totally readable, till you cease scrolling.
Movement smoothing is why some folks declare that after you have used a 120Hz cellphone, you will by no means need to return. Personally, I do not thoughts 60Hz panels that a lot, however I can perceive why others would really feel they are a main downgrade. It is definitely unusual that Apple has refused to place 120Hz panels into $800 smartphones till now.

All the time-on show expertise
No have to unlock to test the time or climate
Strictly talking, 120Hz telephones do not routinely assist always-on expertise, however they often do lately. Those that do supply it depend on dynamic refresh charges, typically scaling right down to as little as 1Hz — one body per second. A cellphone working at each 1Hz and dimmed brightness consumes a trivial quantity of energy, opening up new potentialities to your lockscreen.
At a minimal, always-on tech is used to show the time and different fundamental information, akin to battery ranges, saving you the inconvenience of getting to unlock your cellphone or faucet the display to wake it. Extra superior implementations can present your notifications, and/or customizable widgets for options like climate forecasts, media playback, and good house management. For this very motive, I preserve my iPhone 16 Professional propped up on a stand in the course of the workday. It saves time to know at a look who’s messaging me, and whether or not I ought to anticipate rain after I’m headed out afterward my EUC.
At evening, I benefit from an iOS function known as
StandBy
. Principally, it simply lets me test the time with out choosing up my cellphone and blinding myself, however that in itself is efficacious for maximizing my sleep. It is a small pleasure to know it is 2:40AM and I can fall again asleep in just a few moments.

Extra environment friendly energy consumption
No have to go full-tilt for each scene
You may suppose 60Hz telephones could be extra power-efficient, however for technical causes they’re inherently locked at that refresh charge, no matter what’s occurring onscreen. With dynamic charges, 120Hz telephones can scale down at any time when much less energy is required. A cellphone may dip to 10Hz if you’re studying a static webpage, for instance, however then ramp again as much as 120Hz if you’re taking part in a recreation like Limbo or Fortnite.
There’s extra to say about that within the subsequent part.
Even higher consumption could also be attainable by disabling always-on options, and/or selecting a decrease charge cap whereas nonetheless preserving dynamic scaling. The probabilities are going to rely on the precise cellphone you personal and its software program choices, so it is price researching tech specs and opinions before you purchase.

Slicker, extra responsive gaming
So long as you have bought the processor to match
One in all Nvidia’s better-known advertising slogans is “frames win video games,” and that is not completely hype. Sooner framerates allow faster reactions — one thing I do know first-hand from my growing older PC, since I’ve misplaced quite a lot of PUBG matches as a result of an opponent was in a position to hearth a shot a split-second earlier. Poor framerates can also make you miss a leap in a platformer, or a block in a preventing recreation.
Granted, the main limitation on framerates is your cellphone’s processor — you are going to get higher efficiency out of the Tensor G4 in a Pixel 9 than the Tensor G3 in a Pixel 8. But when your cellphone’s show is caught at 60Hz, you will by no means see framerates over 60fps, no matter whether or not you have bought a supercomputer below the hood. A 120Hz panel successfully eliminates this type of bottlenecking.

Faster contact response
Your mileage might differ
Personally, I do not discover 120Hz telephones to be that rather more responsive than 60Hz ones. I used to be contemplating leaving this level out of the article, in actual fact. However different folks say it is a tangible profit, so I assumed it will not less than be price mentioning.
The declare does make some sense, on condition that it is actually simply an extension of the smoother software program expertise I discussed in the beginning. As a result of the interface itself is animating quicker, you might even see marginally shorter delays for contact and faucet gestures. It will most likely matter essentially the most if you’re typing — if a key animation flashes for just a few dozen milliseconds much less, you might be much less prone to make a mistake, assuming you are a rapid-fire typist. If you happen to take your time with typing, you might not discover any distinction in any respect. I might encourage going slower anyway, for the sake of placing extra thought into messages.
