If your Xiaomi 15 Ultra does not vibrate the way you expect during incoming calls, you might miss calls or feel that the vibration is too weak, too strong, or inconsistent. This usually happens because of vibration settings, sound profiles, or system optimizations in MIUI or HyperOS. The good news is that you can customize the vibration pattern and fix most related issues in just a few steps.
Why Your Xiaomi 15 Ultra Incoming Call Vibration Is Not Working Properly
- Vibration intensity is set too low or disabled.
- The phone is in Silent or Do Not Disturb mode.
- The selected vibration pattern is not applied correctly.
- System optimization is limiting vibration feedback.
- Software glitches after a recent update.
Change the Incoming Call Vibration Pattern
Customizing the vibration pattern helps you recognize calls instantly, even when your phone is in your pocket. This also ensures the vibration style matches your preference, whether you want something subtle or more noticeable.
Open Settings, and then tap Sound and vibration.
Tap Vibration, and then select Incoming calls.
Choose a vibration pattern from the list, and test it before exiting.
Increase Vibration Intensity
If the vibration feels weak, increasing the intensity can make a big difference. Stronger vibration helps ensure you feel incoming calls in noisy environments or when the phone is in a bag.
Open Settings, and then tap Sound and vibration.
Tap Vibration intensity, and then adjust the slider for Calls.
Lock your phone and test the vibration by asking someone to call you.
Check Silent and Do Not Disturb Modes
Silent mode and Do Not Disturb can block or limit vibration for calls. Even if sound is muted, vibration settings may also be affected.
Swipe down to open the Control Center, and then tap the Silent or Do Not Disturb icon.
Turn it off, and then check your vibration behavior again.
Make Sure Call Vibration Is Enabled
Sometimes vibration is disabled only for calls, while notifications still vibrate normally. This setting is easy to miss.
Open Settings, and then tap Sound and vibration.
Toggle on Vibrate for calls, and confirm the change.
Test by locking the phone and receiving a call.
Restart the Phone
A restart refreshes system services that control vibration feedback. This helps when the vibration suddenly stops working after long uptime or background app conflicts.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up, and test the vibration again.
Update the System Software
Software updates often fix vibration bugs and improve haptic performance. Running an outdated version can cause inconsistent vibration behavior.
Open Settings, and then tap About phone.
Tap System update, and check for available updates.
Install any updates, then restart the phone.
Once your vibration pattern is set correctly and system restrictions are cleared, incoming call vibrations on the Xiaomi 15 Ultra should feel consistent and reliable again. A few small adjustments are usually enough to restore proper vibration behavior.
FAQs
Why does my Xiaomi 15 Ultra vibrate sometimes but not always for calls?
This often happens when Do Not Disturb rules or battery optimizations restrict vibration under certain conditions. Checking these settings usually resolves the issue.
Can I create a custom vibration pattern on Xiaomi phones?
Some MIUI and HyperOS versions allow limited customization. If custom patterns are not available, you can choose from built-in vibration styles.
Does using strong vibration affect battery life?
Stronger vibration uses slightly more power, but the impact is minimal and unlikely to affect daily battery performance.
