If calls on your Xiaomi 15 Ultra sound too quiet, even at full volume, it can make conversations frustrating. Voices may feel distant, muffled, or hard to understand in normal environments. This issue is usually caused by simple settings, audio routing problems, or temporary software hiccups, all of which you can fix in minutes.
Why Your Xiaomi 15 Ultra Call Volume Is Too Low
- The in-call volume level is set too low during active calls.
- Speaker or earpiece openings are partially blocked by dust or debris.
- Audio output is being routed to Bluetooth or another connected device.
- Sound enhancement or accessibility settings are interfering with call audio.
- Temporary system glitches affecting call audio performance.
1. Increase the In-Call Volume Properly
Call volume can only be adjusted while you are on an active call. Many users raise the volume outside a call, which does not affect call audio at all.
Make a phone call, and then press the Volume Up key during the call.
Keep pressing it until the on-screen call volume indicator reaches maximum.
2. Check for Connected Bluetooth Devices
If your phone is connected to earbuds, a car system, or a smartwatch, call audio may be routed away from the earpiece. This makes calls sound quiet even when the volume is high.
Open Settings, and then tap Bluetooth.
Turn Bluetooth off, and then place another call to test the volume.
3. Clean the Earpiece Speaker
Dust and pocket lint can block the earpiece grille, which lowers call volume over time. This is common if the phone is often kept in pockets or bags.
Inspect the top earpiece area, and then gently clean it with a soft brush.
Remove any visible debris, and then test call volume again.
4. Disable Call Sound Enhancements
Some audio enhancement features can distort or reduce call clarity. Turning them off helps restore normal voice levels.
Open Settings, and then tap Sound and vibration.
Tap Sound effects, and then turn off audio enhancements related to calls.
5. Check Accessibility Audio Settings
Accessibility features are helpful, but some options can unintentionally limit call volume. Adjusting them often fixes unusually low audio.
Open Settings, and then tap Accessibility.
Tap Hearing, and then disable any call-related audio limits or balance adjustments.
6. Restart Your Phone
A restart refreshes the audio system and clears temporary glitches. This step is simple, but it often solves call volume issues immediately.
Swipe down from the top of the screen, and then tap the Power icon.
Tap Restart, and then wait for the phone to boot back up.
Low call volume on the Xiaomi 15 Ultra is rarely a hardware failure. Once you adjust the correct settings and clear audio conflicts, calls should sound loud and clear again.
FAQs
Why does call volume sound fine on speaker but low on the earpiece?
This usually points to a partially blocked earpiece or incorrect in-call volume level. Cleaning the earpiece and adjusting volume during a call often fixes it.
Can a software update cause low call volume?
Yes. Some updates may reset sound settings or introduce temporary bugs. Restarting the phone and checking audio settings usually resolves this.
When should I contact Xiaomi support?
If call volume stays low after cleaning the earpiece and adjusting all settings, the speaker hardware may be damaged. In that case, professional service is recommended.
