How to run a phone vibration test on your iPhone
To run a clear phone vibration test on your iPhone, check two iOS switches first so a disabled setting does not look like a motor issue. Next, open Massager and drag the Strength slider from 10% to 100% to feel steady vibration across the full range. You can test without creating an account.
Step-by-step iPhone vibration motor check
Follow this order on any iPhone running iOS 16.6 or later.
- Open Settings > Accessibility > Touch > Vibration and make sure the switch is on. When this switch is off, all vibration on your iPhone stops.
- Open Settings > Sounds & Haptics and confirm System Haptics is turned on.
- Download and open Massager from the App Store, then tap Start on the home screen to begin continuous vibration.
- Move the Strength slider slowly from 10% up to 100% and check that the vibration gets stronger as you go.
- Switch to the Patterns tab and play one of the free rhythm patterns to check how short pulses feel.
- Tap Stop when your check is complete.
What to check when vibration feels weak
Vibration strength depends on your iPhone model, so 100% on one iPhone can feel different from 100% on another. Trying both steady vibration and short pulses shows you how your iPhone responds in each mode.
If output feels faint, recheck Settings > Sounds & Haptics (System Haptics) and Settings > Accessibility > Touch > Vibration. In Massager, check that the Strength slider on the home screen is set to 100%. On the Patterns tab, turn on Boost to add a continuous base vibration under a rhythm pattern. The free version includes 3 tries of Boost.
Why the built-in custom vibration is not a test
Settings > Sounds & Haptics > Ringtone > Haptics > Create New Vibration only sets the rhythm used for calls and alerts. It cannot adjust strength and it cannot vibrate continuously. Massager lets you hold steady vibration and move from 10% to 100% while it runs, though long vibration uses battery faster. The free version has ads and includes continuous mode, the first 3 of 12 rhythm patterns, and 4 of 15 presets. Your settings stay on your iPhone.
