Bluetooth audio cutting out on the OnePlus 15 can quickly ruin calls, music, or videos. One moment the sound is clear, then it drops, stutters, or disconnects without warning. This issue is usually caused by software settings, interference, or battery restrictions, and most of the time, it can be fixed without advanced troubleshooting.
Why OnePlus 15 Bluetooth Audio Keeps Cutting Out
- Bluetooth cache or connection data is corrupted.
- Battery optimization is restricting background Bluetooth activity.
- Interference from nearby wireless devices.
- Audio codec compatibility issues with headphones or speakers.
- Temporary system bugs after a software update.
Clear and Reconnect the Bluetooth Connection
Bluetooth connections can become unstable over time, especially if the device has paired with many accessories. Removing the connection and pairing again refreshes the link and clears minor data conflicts.
Open Settings, and then tap Bluetooth.
Tap the connected audio device, and then select Forget.
Restart Bluetooth and pair the device again from scratch.
Turn Off Battery Optimization for Bluetooth
Battery optimization can limit Bluetooth performance in the background, especially when the screen is off. Disabling this restriction helps maintain a stable audio stream during playback.
Open Settings, and then tap Battery.
Tap Battery optimization, and then locate Bluetooth services.
Set them to Unrestricted or Not optimized.
Disable Nearby Device Interference
Bluetooth shares frequency space with Wi Fi and other wireless signals. Too much interference can cause audio to stutter or drop entirely.
Move away from crowded wireless environments if possible.
Turn off unused Bluetooth devices nearby.
Test audio again in an open area.
Change the Bluetooth Audio Codec
Some headphones do not work well with certain audio codecs. Switching to a more stable codec can significantly improve connection quality.
Open Settings, and then tap About phone.
Tap Build number multiple times to enable Developer options.
Go back to Settings, open Developer options, and change the Bluetooth audio codec to SBC or AAC.
Restart the Phone
A simple restart refreshes Bluetooth services and clears temporary system glitches. This step often fixes audio dropouts caused by background conflicts.
Open Settings, and then tap Power.
Tap Restart, and allow the phone to reboot fully.
Reconnect your Bluetooth audio device after restart.
Update the System Software
Software updates often include Bluetooth stability fixes. Running an outdated version may expose you to bugs already patched by OnePlus.
Open Settings, and then tap Software update.
Check for updates, and install the latest version if available.
Restart the phone after the update completes.
Bluetooth audio issues on the OnePlus 15 are rarely hardware related. Once you clear old connections, adjust battery settings, and reduce interference, audio playback usually becomes stable again.
FAQs
Why does Bluetooth audio cut out only when the screen is off?
This usually happens when battery optimization restricts Bluetooth in the background. Allowing unrestricted battery usage fixes the problem.
Does Wi Fi affect Bluetooth audio quality?
Yes. Wi Fi networks, especially on crowded channels, can interfere with Bluetooth signals and cause audio interruptions.
Should I reset network settings if nothing works?
If audio still cuts out after all steps, resetting network settings can help, but it should be a last resort since it removes saved Wi Fi and Bluetooth connections.
