How to Disable ProMotion Max on iPhone 17 Pro to Save Battery
To extend battery life on your iPhone 17 Pro, you can reduce the display’s power consumption by limiting its adaptive refresh rate. Apple’s ProMotion technology dynamically scales up to 120Hz for smooth motion but uses more energy. Here’s how to cap it at 60Hz.
⚙️ Primary Method: Enable ‘Limit Frame Rate’
The most effective setting is found in Accessibility, not Display settings.
| Setting Path | Action | Effect on Battery & Display |
|---|---|---|
| Settings > Accessibility > Motion > Limit Frame Rate | Toggle ON. | Caps max refresh rate at ~60Hz, reducing power draw from the display. Animations will be less fluid. |
Important Note: There is no direct “Disable ProMotion” toggle. This is the official method to restrict the higher refresh rates.
🔋 Complementary Display & Battery Settings
For maximum savings, combine frame rate limiting with these adjustments.
| Setting Category | Specific Action | Battery Benefit |
|---|---|---|
| Brightness | Enable Auto-Brightness (Settings > Accessibility > Display & Text Size). | Preverts unnecessarily high manual brightness. |
| Screen Timeout | Set Auto-Lock to 30 seconds or 1 minute (Settings > Display & Brightness). | Turns off the display faster during inactivity. |
| Always-On Display | Turn Off (Settings > Display & Brightness > Always On Display). | Stops the lock screen from staying lit. |
| System-Wide Savings | Enable Low Power Mode (Control Center or Settings > Battery). | Automatically limits background activity and caps refresh rate. |
📝 Step-by-Step: How to Limit Frame Rate
-
Open the Settings app on your iPhone 17 Pro.
-
Scroll down and tap Accessibility.
-
Tap Motion.
-
Toggle the switch for “Limit Frame Rate” to the ON position (green).
-
Exit Settings. The change is immediate—scrolling and animations will now feel less smooth but use less power.
❓ Frequently Asked Questions
-
Will I notice a big difference in smoothness?
Yes, but mainly during rapid scrolling or in high-motion apps. For static content (reading, messaging) and slower UI animations, the difference is subtle for many users. -
Does Low Power Mode do the same thing?
Yes. Enabling Low Power Mode automatically limits the display’s refresh rate alongside other system optimizations, making it a convenient one-tap solution. -
Is this the same as turning off ProMotion?
Functionally, yes. This setting prevents the display from entering the higher refresh rate tiers (e.g., 90Hz, 120Hz) of the ProMotion spectrum, effectively disabling its core adaptive high-refresh-rate feature. -
Can I set a custom refresh rate, like 90Hz?
No. iOS only provides a binary choice: the full adaptive range of ProMotion (up to 120Hz) or a capped rate at approximately 60Hz.
✅ Summary of Key Actions
To save battery by managing ProMotion on your iPhone 17 Pro:
-
Go to Settings > Accessibility > Motion and turn ON “Limit Frame Rate.”
-
For further savings, enable Auto-Brightness, shorten Auto-Lock, and turn off Always-On Display.
-
Use Low Power Mode for automatic, comprehensive power management.
Limiting the frame rate is a direct trade-off between visual smoothness and battery endurance, providing a practical way to gain more usage time from a single charge.
