Phone Bluetooth Audio Keeps Cutting Out: Causes and Fixes

Published 2026-10-16 · Marion Phone Repair

You are listening to music or a podcast through Bluetooth headphones or a Bluetooth speaker, and the audio keeps cutting out — stuttering, skipping, going silent for a second, or dropping the connection entirely. This is one of the most common Bluetooth complaints and it almost always has a fixable cause. Here is how to diagnose and resolve it.

Quick fixes to try first

Toggle Bluetooth off and on

Turn Bluetooth off on your phone, wait 10 seconds, and turn it back on. This forces the phone to re-establish the connection with your audio device. On iPhone, use Settings (not Control Center — the Control Center Bluetooth toggle only disconnects devices temporarily, it does not fully turn off Bluetooth). On Android, use Settings, Connected Devices or Bluetooth.

Restart both devices

Restart your phone and power cycle your Bluetooth headphones or speaker (turn them off, wait 10 seconds, turn them on). Bluetooth connections involve software stacks on both sides, and either one can develop glitches that a restart clears.

Charge both devices

Low battery on either the phone or the Bluetooth device can cause audio dropouts. Some Bluetooth headphones and speakers reduce their Bluetooth transmission power when battery is low to conserve energy, which weakens the connection and causes skips. Charge both devices above 50 percent and test again.

Interference and range issues

Bluetooth operates on the 2.4 GHz frequency band, which is shared with Wi-Fi, microwave ovens, USB 3.0 devices, baby monitors, wireless mice and keyboards, and other electronics. Interference from these devices is the most common cause of Bluetooth audio cutting out.

Common interference sources

Wi-Fi routers: If your phone is connected to a 2.4 GHz Wi-Fi network and streaming Bluetooth audio simultaneously, the two radios can interfere with each other. Try switching your Wi-Fi connection to a 5 GHz network if your router supports it
Microwave ovens: Active microwaves produce significant 2.4 GHz interference. If your audio cuts out when someone is using the microwave, this is the cause — wait until the microwave finishes or move to another room
Crowded environments: Shopping malls, airports, offices, and apartment buildings have dozens of active Bluetooth and Wi-Fi devices. The 2.4 GHz band becomes congested, causing packet loss that manifests as audio skips. Newer Bluetooth 5.0 and above handles congestion better than older versions
Your body: Bluetooth is a low-power signal, and your body absorbs some of it. If your phone is in your back pocket and your headphones are in your ears, the signal passes through your body and can be weakened enough to cause dropouts. Try keeping the phone on the same side as the Bluetooth device or in a front pocket

Range

Standard Bluetooth has a practical range of about 30 feet (10 meters) in open air, but walls, furniture, and other obstacles reduce this significantly. A single wall can cut effective range in half. If you walk to another room while your phone is charging in the bedroom, expect audio interruptions. Keep the phone and the Bluetooth device within the same room for the most reliable connection.

Software fixes

Forget and re-pair the device

The Bluetooth pairing profile stored on your phone may be corrupted. Remove the device and pair it fresh:

iPhone: Go to Settings, Bluetooth, find the device, tap the info button (the i icon), and tap Forget This Device. Then put your Bluetooth device back into pairing mode and connect again
Android: Go to Settings, Connected Devices (or Bluetooth), find the device, tap the gear icon, and tap Forget or Unpair. Then re-pair from scratch

Reset network settings

This resets all Bluetooth pairings, Wi-Fi passwords, and cellular settings to defaults. It is more thorough than forgetting a single device and can resolve persistent Bluetooth issues:

iPhone: Settings, General, Transfer or Reset iPhone, Reset, Reset Network Settings
Android: Settings, System (or General Management), Reset, Reset Network Settings (or Reset Wi-Fi, Mobile, and Bluetooth)

You will need to re-enter Wi-Fi passwords and re-pair all Bluetooth devices after this reset.

Update firmware on your Bluetooth device

Many Bluetooth headphones and speakers (especially from brands like Sony, Bose, Jabra, Samsung, and Apple) receive firmware updates through a companion app. These updates often fix connectivity and audio quality issues. Check whether your device has a companion app and if a firmware update is available.

Disable battery optimization for music apps (Android)

If audio cuts out specifically when your phone's screen is off or the music app is in the background, Android's battery optimization may be suspending the music app. Go to Settings, Apps, find your music app (Spotify, YouTube Music, etc.), Battery, and set it to Unrestricted. This prevents Android from pausing the app's background activity.

Bluetooth codec settings (Android)

Android allows you to change the Bluetooth audio codec, which affects audio quality and connection stability. To access these settings, you need to enable Developer Options (Settings, About Phone, tap Build Number 7 times), then go to Settings, Developer Options, and look for Bluetooth Audio Codec:

SBC: The default and most compatible codec. If you are experiencing dropouts, switching to SBC from a higher-quality codec may improve stability
AAC: Higher quality than SBC, used by default for Apple devices. Generally stable but uses more processing power
aptX / aptX HD / LDAC: Higher quality codecs that require more Bluetooth bandwidth. If you are using one of these and experiencing dropouts, switch to SBC or AAC to see if the connection stabilizes. Higher-quality codecs are more sensitive to interference and range limitations

Hardware causes

If none of the above fixes resolve the issue, the problem may be hardware-related:

Damaged Bluetooth antenna: The phone's Bluetooth antenna can be damaged by drops or water exposure. If Bluetooth range has decreased noticeably (devices disconnect within a few feet) or multiple Bluetooth devices have connection issues with the same phone, the antenna may be damaged
Worn-out Bluetooth device: Headphones and speakers have a limited lifespan. If a specific Bluetooth device has connection problems with multiple phones, the issue is with that device, not your phone
Bluetooth version mismatch: Older Bluetooth devices (4.0 and below) paired with newer phones can have compatibility issues. While they should work, the connection may be less stable than pairing devices of similar Bluetooth versions
