A 185Hz phone display can update its image more often than a 120Hz display, which can make supported games and fast scrolling look smoother. It does not make every game run at 185 frames per second, and the available manufacturer specifications do not establish how much battery life the higher refresh mode costs. The difference matters most when the phone and the content can both make use of the extra display updates.
What 185Hz means on a phone
Hertz (Hz) describes how often a display can refresh its image in one second. A 185Hz screen has a maximum refresh rate of 185 updates per second; a 120Hz screen has a maximum of 120. Those are display capabilities, not promises about how many distinct images a game or video will produce.
At the maximum rates, the time between potential display updates is about 5.4 milliseconds at 185Hz, 8.3 milliseconds at 120Hz, and 16.7 milliseconds at 60Hz. These intervals are simple calculations from the stated refresh rates. They help explain why a higher rate can present changes more frequently, but they do not by themselves measure how responsive a particular phone feels or how many frames an app renders.
ASUS identifies the ROG Phone 9 and ROG Phone 9 Pro as phones with a display mode of up to 185Hz through Game Genie. ASUS’s ROG Phone 9 product page specifies a 6.78-inch E6 AMOLED display. These are model-specific manufacturer specifications, not a standard capability shared by phones generally. ASUS does not state a publication year for the specifications on the pages described here.

How display refresh rate differs from game frame rate
Refresh rate is the screen’s capacity to update. Frame rate is how often a game or other app creates new images. A display set to 185Hz can only show new game frames as quickly as the game produces them and the phone can render them. If a game produces fewer frames, the extra display capacity cannot turn those frames into additional game-rendered images.
For example, if a game produces 60 new frames each second, selecting a higher display refresh rate does not make that game produce 185 frames per second. The screen may still refresh more often, but some refreshes will not contain a new game frame. Conversely, a game that supports a high frame rate and a phone that can sustain it may make better use of the 185Hz ceiling. The ASUS product specifications establish the display’s maximum mode, but do not provide a title-by-title list of games that can render at 185 frames per second.
Performance can also vary during a session. A game may not sustain its highest frame rate in every scene or throughout a long session. The product-page specifications cited here do not establish how the ROG Phone 9 performs in individual games over time, so the 185Hz figure should be treated as a display maximum rather than a guarantee of sustained gameplay performance.

Motion can look smoother when the game supplies enough frames
When a game renders new frames quickly enough, the screen has more opportunities to show them. That can make fast motion, camera turns, and moving objects look more fluid than on a lower-refresh display. The benefit depends on the game’s frame-rate support and the phone’s ability to render those frames; the maximum refresh number alone does not tell you whether a particular game will visibly benefit.

Higher refresh can be most noticeable in games with frequent movement and rapid changes on screen. It is less consequential when a title runs at a lower frame rate, uses slower-paced visuals, or otherwise does not supply new images at a rate that takes advantage of the display. ASUS’s official pages do not publish a game compatibility matrix or a controlled comparison of perceived smoothness at 185Hz versus lower settings.
Touch sampling is a separate input specification
ASUS lists 720Hz touch sampling alongside the ROG Phone 9’s up-to-185Hz display refresh. These numbers refer to different parts of the interaction chain: refresh rate describes display updates, while touch sampling describes how frequently the touch system samples input. A higher touch-sampling figure is not a higher game frame rate, and it should not be added to or substituted for the display’s refresh rate.
Touch sampling can be relevant to how often the phone checks for a finger input, but the specification alone does not establish end-to-end game responsiveness. That experience also depends on the game, rendering, display behavior, and other parts of the device. The listed 720Hz figure is therefore useful as a separate specification, not proof that every action will be registered or shown at a particular speed.
185Hz is not a complete gaming specification
When considering a high-refresh phone for games, compare the maximum refresh mode with the frame rates supported by the games you actually play. Also consider whether the phone sustains its performance during longer sessions, how touch input is specified, and whether its battery behavior fits your use. The cited ASUS pages provide refresh, touch-sampling, adaptive-refresh, and battery specifications, but not controlled cross-device testing or game-by-game performance results.

What changes during scrolling
Scrolling is another situation in which more frequent display updates can make motion appear smoother. Text and interface elements move across the screen as you swipe; a display capable of refreshing more often can show intermediate positions more frequently when the interface supplies updates to match. This can make a high-refresh screen feel more fluid during fast scrolling than a lower-refresh screen.
The 185Hz maximum does not mean every swipe, app, or screen runs at that rate all the time. ASUS describes the ROG Phone 9 display as adaptive, so its refresh behavior can vary rather than remain fixed at the maximum. The actual experience depends on the phone’s operating mode and the content being shown. The cited product pages do not provide a controlled scrolling comparison between 185Hz and lower settings, so they do not establish a measured degree of smoothness improvement.
For everyday use, the practical question is whether you notice and value the smoother motion enough to prefer the mode that enables it. If your main use is static reading, messaging, or viewing content that changes slowly, a 185Hz ceiling may matter less than it does for rapid scrolling or compatible games. This is a use-case distinction, not a claim that the display changes image quality in every app.

A higher refresh mode can have a battery cost, but the amount depends on the phone’s adaptive behavior and what the device is doing. A game that continually renders demanding scenes is a different workload from reading a static page. ASUS says the ROG Phone 9’s display uses adaptive refresh rates to minimize power usage, but its product pages do not publish a controlled test comparing the same phone at 185Hz and a lower refresh setting.

That means there is no substantiated figure here for how many minutes or percentage points of battery life 185Hz uses compared with 120Hz or 60Hz. It would be misleading to treat the phone’s general endurance figures as a measured 185Hz penalty, or to infer a precise drain difference from the maximum refresh rate alone.
ASUS lists a 5800mAh battery for the ROG Phone 9 and publishes these endurance figures for the ROG Phone 9 family:
| Manufacturer-listed activity | ASUS-published figure | What the specification does not establish |
|---|---|---|
| Heavy gaming | At least 4.5 hours | The refresh mode used or a 185Hz-versus-lower-rate comparison |
| Video streaming | 22.1 hours | The refresh mode used or a controlled comparison with another refresh setting |
| Social-media scrolling | 23.4 hours | The refresh mode used or a controlled comparison with another refresh setting |
These are manufacturer-published figures, not independent comparative test results. The cited pages do not state the refresh mode or test protocol behind the durations. They describe the manufacturer’s listed endurance, but cannot tell a buyer what runtime to expect specifically with 185Hz enabled.

If battery runtime matters more than the smoothest possible motion, use an adaptive or lower refresh behavior if the phone provides it, then judge the balance against your own mix of gaming, scrolling, and other use. If you prefer the higher mode, expect that the workload and operating mode can affect battery behavior, but do not assume a specific penalty without a comparable test. The available ASUS specifications support neither a precise battery-cost estimate nor a claim that 185Hz always drains the battery at a fixed rate.

How to decide whether 185Hz is useful to you
Use the following checks to judge the feature rather than buying or changing settings based on the headline number alone:
- Check the games you play. Look for whether each game supports a sufficiently high frame rate on the phone. The ROG Phone 9 specification does not list individual games or promise that all titles can use 185Hz.
- Separate a display maximum from a sustained result. “Up to 185Hz” describes a maximum mode available through Game Genie; it does not state that every game will render at that rate continuously.
- Consider how you use the phone. Fast gameplay and scrolling are more likely to reveal smoother motion than static reading or content that changes slowly.
- Keep touch sampling in its own category. ASUS’s 720Hz touch-sampling figure is not another way of stating refresh rate or game frame rate.
- Decide how much battery trade-off you will accept. ASUS says adaptive refresh rates minimize power usage, but does not quantify the difference between 185Hz and a lower setting.
- Weigh the whole device. Refresh rate is one part of a phone’s display and performance experience. The cited specifications do not provide a cross-device controlled comparison that would make 185Hz alone a complete buying decision.
Other display claims and what they do—and do not—tell you
ASUS says the ROG Phone 9 has “Eye Protection Mode in all refresh rate settings.” That is a manufacturer statement about a product feature, not independent evidence of a health effect. It does not change the meaning of 185Hz or establish that a particular refresh setting is better for every user.
Similarly, the 6.78-inch E6 AMOLED designation describes the ROG Phone 9 display, while 185Hz describes its maximum refresh capability. Neither specification on its own establishes how an individual will perceive the screen, how well a particular game runs, or how long the battery will last in a given mode.

Bottom line for gaming, scrolling, and battery
A 185Hz display raises the maximum frequency at which the screen can update, giving compatible games and fast-moving interfaces room to look smoother than they can on a lower-refresh display. The ROG Phone 9 and ROG Phone 9 Pro are specific examples with a manufacturer-listed maximum of 185Hz through Game Genie. To realize the benefit in a game, that game and the phone must also supply frames at a suitable rate.
For battery life, the evidence supports a more limited conclusion: ASUS describes adaptive refresh as a way to minimize power use and publishes general endurance figures, but does not identify the refresh mode behind those figures or quantify the battery difference between 185Hz and a lower rate. Treat 185Hz as a potential motion-smoothness benefit, not a guaranteed frame rate or a known battery-life penalty.
