The iPhone’s screen refresh rate isn’t just a technical detail—it’s a silent influencer of your device’s performance, battery life, and visual fluidity. Whether you’re a power user chasing smoother animations or a casual owner looking to extend battery endurance, adjusting how your iPhone refreshes its display can make a tangible difference. Yet, despite its impact, this setting remains buried in iOS’s labyrinthine menus, accessible only to those who know where to look.
Apple’s decision to make refresh rate adjustments optional—especially on ProMotion-enabled iPhones—stems from a calculated balance between user experience and hardware constraints. The 120Hz screens on iPhone Pro models deliver buttery-smooth scrolling and gaming, but they also demand more power. For most users, the default 60Hz is sufficient, but for others, the trade-off between performance and battery life becomes a daily negotiation. The question isn’t just *how to change refresh rate on iPhone*, but *when* and *why* you should.
What follows is a meticulous breakdown of how to navigate iOS’s refresh rate settings, the science behind why they matter, and the practical implications of tweaking them. From historical context to future trends, this guide covers everything you need to know—without the fluff.
The Complete Overview of Adjusting iPhone Refresh Rate
Changing your iPhone’s refresh rate is a two-step process: locating the setting and understanding its trade-offs. On iPhones with ProMotion (120Hz displays), Apple allows users to switch between 10Hz, 60Hz, and 120Hz via Control Center—a feature introduced in iOS 17. For older models or non-Pro iPhones, the refresh rate is fixed at 60Hz, but there are still indirect ways to influence how the screen behaves, such as adjusting brightness or enabling Dark Mode to reduce power draw.
The catch? Apple’s default behavior leans toward convenience over customization. While the ability to toggle refresh rates exists, it’s not immediately obvious, and many users remain unaware of its existence. This oversight is particularly glaring in an era where display technology directly impacts everything from productivity to entertainment. Whether you’re a developer testing apps or a gamer seeking competitive edge, knowing *how to change refresh rate on iPhone* can unlock a new layer of control over your device.
Historical Background and Evolution
The concept of refresh rates in mobile displays traces back to the early 2010s, when high-refresh-rate OLED panels began appearing in flagship Android devices. Samsung’s Galaxy Note 3 (2013) and later the Galaxy S6 Edge (2015) popularized 120Hz screens, but Apple remained skeptical, citing battery life concerns. The iPhone 13 Pro changed the game in 2021, introducing ProMotion—a 120Hz adaptive refresh rate that dynamically adjusts based on content. This was a departure from Android’s static high-refresh-rate approach, emphasizing efficiency over raw numbers.
Apple’s reticence to adopt high-refresh-rate displays for years wasn’t just about battery life; it was a strategic choice to prioritize longevity and thermal management. The iPhone 13 Pro’s ProMotion was a compromise: it offered the smoothness of 120Hz when needed (e.g., scrolling or gaming) but defaulted to 10Hz or 60Hz to conserve power. The addition of manual refresh rate toggling in iOS 17 was a direct response to user demand, proving that even Apple’s most guarded hardware features can evolve with the right feedback.
Core Mechanisms: How It Works
At its core, a refresh rate determines how many times per second your iPhone’s display repaints its screen. A 60Hz display updates 60 times a second, while 120Hz doubles that, resulting in smoother motion but higher power consumption. ProMotion iPhones use an adaptive algorithm to switch between these rates dynamically, but manual control gives users finer-grained adjustments. For example, setting it to 10Hz (the lowest) can extend battery life by up to 2 hours in some scenarios, while 120Hz is ideal for fast-paced tasks like video editing or mobile gaming.
The trade-off isn’t just about performance versus battery—it’s also about visual comfort. Lower refresh rates can cause motion blur in fast-moving content, while higher rates reduce eye strain during prolonged use. Apple’s adaptive approach mitigates these issues by balancing efficiency and responsiveness, but manual overrides are necessary for users with specific needs, such as color graders who require consistent refresh rates for accurate calibration.
Key Benefits and Crucial Impact
Adjusting your iPhone’s refresh rate isn’t a trivial tweak; it’s a performance multiplier. For gamers, the difference between 60Hz and 120Hz can mean the difference between a laggy experience and a competitive advantage. For creatives, stable refresh rates ensure color accuracy and reduce visual artifacts. Even casual users benefit from reduced eye strain and longer battery life when they lower the refresh rate during passive activities like reading or browsing.
The impact extends beyond individual users. Developers optimizing apps for ProMotion iPhones must account for variable refresh rates, leading to more adaptive UI/UX designs. Meanwhile, Apple’s hardware engineers continue to refine power management to make high-refresh-rate displays viable for extended use. The ability to *change refresh rate on iPhone* isn’t just a user preference—it’s a reflection of how display technology is becoming more interactive and personalized.
"The refresh rate isn’t just about numbers; it’s about how technology responds to human behavior. A 120Hz screen doesn’t just show content faster—it changes how we interact with it."

Comprehensive FAQs
Q: Can I change the refresh rate on any iPhone model?
A: No. Only iPhones with ProMotion displays (iPhone 13 Pro and later) support adjustable refresh rates. Non-Pro models are locked at 60Hz, though iOS optimizations like Low Power Mode can indirectly influence performance.
Q: Does lowering the refresh rate improve battery life significantly?
A: Yes, but the impact varies. Dropping to 10Hz can add ~1-2 hours of battery life, while switching to 60Hz from 120Hz offers a moderate boost (~30-50 minutes). The difference is most noticeable during passive use (e.g., reading, web browsing).
Q: Why does my iPhone still feel laggy at 120Hz?
A: Lag isn’t solely about refresh rate—it’s also tied to processing power, app optimization, and background tasks. If your iPhone feels sluggish, check for app updates, close unused apps, or enable Developer Mode to test performance metrics.
Q: Can I set a default refresh rate for specific apps?
A: Not natively, but third-party tools like Display Refresh Rate Changer (jailbreak-dependent) or iOS Shortcuts can automate toggles based on app usage. Apple may introduce app-specific controls in future updates.
Q: Will changing the refresh rate void my warranty?
A: No. Adjusting the refresh rate is a software setting and has no impact on hardware warranty coverage. Apple explicitly supports this feature for ProMotion iPhones.
Q: How do I know if my iPhone supports ProMotion?
A: Check your model: iPhone 13 Pro, 14 Pro, 15 Pro, or 16 Pro (and Pro Max variants). Alternatively, go to Settings > Display & Brightness—if you see refresh rate options, you have ProMotion.
Q: Does 120Hz cause more screen burn-in?
A: No. OLED burn-in is caused by static content (e.g., always-on widgets or logos), not refresh rate. However, higher refresh rates may increase pixel degradation over time due to higher power draw, so balancing usage is key.
Q: Can I use third-party apps to force a refresh rate?
A: Officially, no. Apple restricts refresh rate modifications to its built-in settings. Jailbreaking or sideloading apps may offer workarounds, but they risk instability or security vulnerabilities.
Q: Why does my iPhone’s refresh rate change automatically?
A: ProMotion iPhones use adaptive refresh rates to optimize power and performance. The system defaults to 10Hz for static content (e.g., reading) and switches to 60Hz or 120Hz during dynamic tasks (e.g., scrolling). You can disable this by manually selecting a fixed rate.
Q: Does Dark Mode affect refresh rate performance?
A: Indirectly. Dark Mode reduces power draw, which can help sustain higher refresh rates longer. However, the refresh rate itself isn’t altered—it’s a separate setting that works alongside display optimizations.
