Budget phone refresh rate: is 120Hz worth it over 90Hz?

Buying criteria · 6 min read · Published 2026-11-04 · Last updated 2026-11-04

Should a budget buyer pay extra, or give up something else, to get a 120Hz screen instead of a 90Hz one? The honest answer starts with a number most listings bury: on the current Canadian shelf, the cheapest 120Hz phone in this comparison pairs that rate with a 1604 x 720 LCD, while the 90Hz option beside it runs a sharper 1080 x 2340 Super AMOLED panel. Refresh rate alone does not settle this purchase. Resolution, panel type, and the settings on the phone in your hand all vote.

The short answer first

For scrolling, menus, and social feeds, 90Hz already delivers most of the visible step up from 60Hz. The gap between 90Hz and 120Hz is smaller than the jump from 60Hz to either one, a point refresh rate explainers themselves make. A buyer choosing between a 90Hz AMOLED phone and a 120Hz LCD phone at a similar price is not choosing between smooth and rough. That buyer is choosing between a smaller smoothness gain and a sharper, higher contrast screen.

120Hz earns its keep in narrower cases. It helps when a game actually renders at high frame rates, and when the phone carrying it does not ask for a resolution or panel downgrade in exchange. The verified shelf below shows both versions of that trade, model by model.

The verified shelf: rates, panels, and resolution together

Every figure in this table comes from the manufacturer pages and review sources in the research packet for this guide, checked November 4, 2026. Read the refresh column and the resolution column as one decision, not two.

Two patterns matter. First, Samsung's two phones hold resolution constant, so the A36 5G's 120Hz is a clean upgrade over the A17 5G's 90Hz for a buyer already paying the A36 price. Second, Motorola reaches 120Hz at 720p class resolution. Text, icons, and fine detail render at 1604 x 720 no matter how often the screen redraws. A fast refresh cannot add pixels the panel does not have.

What the numbers mean between frames

Refresh rate is the number of times a display updates its image in one second, expressed in Hertz. The arithmetic that follows from that definition explains why the steps feel uneven. At 60Hz a frame lasts about 16.7 milliseconds. At 90Hz it lasts about 11.1 milliseconds. At 120Hz it lasts about 8.3 milliseconds.

Moving from 60Hz to 90Hz cuts the frame time by roughly a third. Moving from 90Hz to 120Hz cuts what remains by about a quarter, off a base that was already small. That shrinking return is the technical version of the smoother scrolling claim, and it is why 90Hz feels like the main event while 120Hz feels like a polish.

There is also a ceiling no setting can lift. A screen cannot display frames an app never sends. Motorola states the limit plainly in its footnote: the actual refresh rate may be less than the maximum, and it varies with app and content limitations as well as mode settings. Video recorded or streamed at a lower frame rate, and games that render at a capped rate, will not fill a 120Hz panel just because the panel can accept 120 updates a second.

The settings that quietly decide your rate

The spec sheet gives a maximum. The settings menu decides how often the phone goes near it, and Samsung's support page documents the three Galaxy options by name. Standard sets the display to 60Hz and, in Samsung's words, provides the best battery life. High can lock a device to its higher rate, 120Hz on some models and 90Hz on others, Samsung's own example being the Galaxy A16 5G at 90Hz, and it uses more battery. Adaptive adjusts the rate dynamically up to the phone's maximum, trading a little smoothness in quiet moments for better battery life in less demanding situations.

One more setting overrides all of them. When Power saving mode is enabled, Samsung says the screen will be set to Standard. A buyer who tests a showroom phone, or a new phone on its first low battery day, may be judging a 60Hz screen while the box says 120Hz. Tom's Guide's Moto G (2025) testing shows the same behaviour from the other side: its battery result was recorded with the display at a default rate that adapts between 60Hz and 120Hz depending on the activity on screen. Adaptive is the factory state on phones like these, not the locked maximum.

The battery direction is consistent across sources. A higher refresh rate means the screen does more work every second, and that costs power. Adaptive ranges exist to spend that power only while something is moving. None of this makes 120Hz a battery disaster. It does mean a locked high rate is a choice with a price, and Standard is a legitimate setting for a long day away from a charger, not a defect.

Set it and check it: the Galaxy procedure

This procedure follows Samsung's published support steps for Galaxy phones. Menu names can vary by model, so use the search step rather than hunting through menus. A buying guide cannot hand over a universal Motorola path from the sources gathered here, and none is invented. Motorola buyers should look for the refresh or display rate control in display settings and confirm the range their model reports.

1. Open Settings and search. From Settings, search for and select Motion smoothness. That is the name Galaxy devices use for the refresh rate control.
2. Open the control and read the current mode. Tap Motion smoothness again. Note whether the phone sits on Standard, High, or Adaptive before changing anything. That starting mode is the screen you have actually been using.
3. Choose Adaptive for daily use. Adaptive gives the high rate during scrolling and animation and steps down when the screen is still. Choose Standard instead for a travel day when battery life matters more than motion. Choose High only to test the locked maximum.
4. Turn Power saving off before judging the screen. With Power saving enabled the display is set to Standard, so a smoothness test run in that state proves nothing about the panel.
5. Run the same scroll twice. Open a long web page or a photo grid and scroll at a steady pace under Adaptive, then under Standard. The difference you can see in that direct swap is the difference the spec is selling.

What success looks like: the Motion smoothness screen shows the mode you chose, scrolling a long page looks visibly steadier on Adaptive or High than on Standard, and switching back to Standard restores the 60Hz behaviour Samsung describes as the best battery option. If all three modes look identical on the content you use, that content is the limit, not the phone.

Who should pay for 120Hz, and who should not

Pay the step up when the 120Hz phone holds the rest of the display constant, as the Galaxy A36 5G does against the A17 5G, and when games or long scrolling sessions fill a real share of the day. Keep the 90Hz phone when the alternative trades resolution or an AMOLED panel to reach 120Hz, as the Moto G (2025) table row does, and when most screen time is reading, messaging, maps, and video, where content frame rates cap the benefit anyway. Ignore the headline entirely when a listing quotes a maximum rate with no range beside it. The range, the panel, and the settings are the spec. The single number is the advertisement.
