Abstract
- The obvious good thing about 120Hz smartphones is smoother movement in apps, and in a telephone’s interface as a complete.
- Many 120Hz telephones additionally help dynamic refresh charges, enabling always-on show capabilities, to not point out higher energy consumption.
- In video games with real-time motion, 120Hz know-how successfully breaks the ceiling on framerates — assuming your processor is highly effective sufficient to prime 60fps.
Like TVs and screens, all telephone shows sport a specific
refresh rate
, referring to how usually they’ll replace what’s onscreen. For a very long time, most smartphones weren’t able to a refresh fee over 60Hz. In truth, that is nonetheless true of non-Professional iPhones — when you just lately upgraded to a baseline
iPhone 16
or iPhone 16e, you would not essentially know that you simply have been lacking something. It is not like Spotify or Google Maps are going to run agonizingly gradual on Apple’s A18 chip.
Today, nonetheless, Execs and plenty of
Android phones
now characteristic 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 would possibly notice, 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 gadget’s interface seems to be. It is a tough factor to elucidate in writing, naturally, however all the things feels snappier, with much less lag or blur. The impact is especially noticeable in apps with a number of scrolling textual content or photographs, akin to an internet browser or an e-book reader. Whereas a 60Hz telephone would possibly sometimes appear like it is “hitching” on issues, a 120Hz telephone seems to maintain issues intact, if not essentially totally readable, till you cease scrolling.
Movement smoothing is why some individuals declare that after you have used a 120Hz telephone, you will by no means wish 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 actually unusual that Apple has refused to place 120Hz panels into $800 smartphones till now.

All the time-on show know-how
No must unlock to verify the time or climate
Strictly talking, 120Hz telephones do not mechanically help always-on know-how, however they normally do nowadays. Those that do provide it depend on dynamic refresh charges, generally scaling right down to as little as 1Hz — one body per second. A telephone working at each 1Hz and dimmed brightness consumes a trivial quantity of energy, opening up new potentialities on your lockscreen.
At a minimal, always-on tech is used to show the time and different primary information, akin to battery ranges, saving you the inconvenience of getting to unlock your telephone 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 sensible dwelling management. For this very purpose, I hold my iPhone 16 Professional propped up on a stand throughout 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 night time, I reap the benefits of an iOS characteristic referred to as
StandBy
. Principally, it simply lets me verify the time with out selecting up my telephone and blinding myself, however that in itself is effective for maximizing my sleep. It is a small pleasure to know it is 2:40AM and I can fall again asleep in a couple of moments.

Extra environment friendly energy consumption
No must go full-tilt for each scene
You would possibly assume 60Hz telephones can be extra power-efficient, however for technical causes they’re inherently locked at that refresh fee, no matter what’s occurring onscreen. With dynamic charges, 120Hz telephones can scale down each time much less energy is required. A telephone would possibly dip to 10Hz whenever you’re studying a static webpage, for instance, however then ramp again as much as 120Hz whenever you’re enjoying a sport 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 fee cap whereas nonetheless preserving dynamic scaling. The chances are going to rely on the precise telephone you personal and its software program choices, so it is value researching tech specs and critiques before you purchase.

Slicker, extra responsive gaming
So long as you have obtained the processor to match
One among Nvidia’s better-known advertising slogans is “frames win video games,” and that is not totally hype. Sooner framerates allow faster reactions — one thing I do know first-hand from my growing old PC, since I’ve misplaced quite a lot of PUBG matches as a result of an opponent was in a position to fireplace a shot a split-second earlier. Poor framerates may additionally make you miss a soar in a platformer, or a block in a preventing sport.
Granted, the main limitation on framerates is your telephone’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 telephone’s show is caught at 60Hz, you will by no means see framerates over 60fps, no matter whether or not you have obtained a supercomputer below the hood. A 120Hz panel successfully eliminates this sort of bottlenecking.

Faster contact response
Your mileage could range
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 individuals say it is a tangible profit, so I assumed it might a minimum of be value mentioning.
The declare does make some sense, on condition that it is actually simply an extension of the smoother software program expertise I discussed firstly. As a result of the interface itself is animating sooner, you might even see marginally shorter delays for contact and faucet gestures. It’s going to in all probability matter essentially the most whenever you’re typing — if a key animation flashes for a couple of dozen milliseconds much less, you could be much less prone to make a mistake, assuming you are a rapid-fire typist. In the event you take your time with typing, you could not discover any distinction in any respect. I would encourage going slower anyway, for the sake of placing extra thought into messages.
