Why Does My Bluetooth Keep Disconnecting? 12 Fixes That Work

Bluetooth keeps disconnecting most often because the devices are too far apart, something is blocking or interfering with the signal, a battery is low, or a power-saving setting is turning Bluetooth off. It can also happen when a device is paired with too many phones or computers and they fight over the connection.

The good news is that most Bluetooth problems can be fixed in a few minutes. Forgetting the device and pairing it again fixes a lot of them.

This guide explains the most common causes and gives you step-by-step fixes for iPhone, Android, Windows, and Mac.

Quick fixes to try first

Before you dig deeper, try these simple steps. They solve most Bluetooth problems.

1. Move closer. Keep the two devices within a few feet of each other.
2. Charge both devices. Low batteries often cause dropouts.
3. Turn Bluetooth off and on on your phone or computer.
4. Restart both devices. Turn the headphones, speaker, or car off and on too.
5. Forget and re-pair the device (see below).

If the problem is still there, keep reading to find the cause.

12 reasons Bluetooth keeps disconnecting

1. The devices are too far apart

Most Bluetooth devices work well up to about 30 feet with nothing in the way. Past that, the signal gets weak and drops.

Fix: Keep your phone or computer closer to the Bluetooth device, especially if there are walls between them.

2. Something is blocking the signal

Bluetooth signals are weak and easy to block. Walls, floors, metal, water, and even your own body can get in the way. A common example is keeping your phone in a back pocket while wearing earbuds. Your body sits between them and blocks the signal.

Fix: Put your phone in a front pocket or on the same side as your earbuds. Keep the phone in the open, not in a bag, when you can.

3. Other wireless signals are interfering

Bluetooth uses the 2.4 GHz radio band. So does older Wi-Fi, many cordless phones, baby monitors, wireless mice, and microwave ovens. When many devices share that band, Bluetooth can drop out.

Fix:

• Move away from microwaves and Wi-Fi routers.
• If your router has a 5 GHz Wi-Fi network, connect your phone or computer to it. This leaves more room for Bluetooth on 2.4 GHz.
• On computers, USB 3.0 ports and devices can interfere with nearby Bluetooth. Plug USB drives and hubs into ports farther away from your Bluetooth receiver.

4. A battery is low

When the battery in your headphones, speaker, mouse, or keyboard gets low, the Bluetooth signal can weaken or cut out. Your phone may also limit Bluetooth when its own battery is low.

Fix: Charge both devices fully and try again.

5. Battery saver is limiting Bluetooth

Power-saving features can turn off or slow down Bluetooth to save battery.

• iPhone: Low Power Mode can affect some background activity. Turn it off in Settings > Battery to test.
• Android: Battery saver or "adaptive battery" can limit Bluetooth for some apps. Turn off battery saver to test. For apps that use Bluetooth, like a fitness or headphone app, go to Settings > Apps, choose the app, tap Battery, and choose Unrestricted.
• Windows: Power management can turn off the Bluetooth adapter to save power (see the Windows section below).

6. The device is connected to more than one phone or computer

Many headphones and speakers remember several devices. If your tablet or laptop is nearby with Bluetooth on, it may grab the connection from your phone.

Fix: Turn off Bluetooth on devices you are not using, or remove the headphones from their Bluetooth lists.

7. The pairing is corrupted

Sometimes the saved connection between two devices gets mixed up. This can cause random dropouts.

Fix: Forget and re-pair the device.

• iPhone: Go to Settings > Bluetooth, tap the i next to the device, and tap Forget This Device.
• Android: Go to Settings > Connected devices (or Connections > Bluetooth), tap the gear icon next to the device, and tap Forget or Unpair.
• Windows: Go to Settings > Bluetooth & devices, click the three dots next to the device, and click Remove device.
• Mac: Go to System Settings > Bluetooth, hover over the device, click the i or the three dots, and click Forget This Device.

Then put the Bluetooth device in pairing mode (check its manual) and connect it again.

8. Your software is out of date

Bugs in your phone, computer, or Bluetooth device's software can cause dropouts. Updates often include Bluetooth fixes.

Fix:

• Update your phone or computer's system software.
• Update the firmware on your headphones, speaker, or car. Many brands have an app for this.

9. Too many devices are connected at once

Connecting a watch, earbuds, a car, and a fitness tracker at the same time can overload some phones, especially older ones.

Fix: Disconnect devices you are not using right now.

10. The Bluetooth device is not compatible

Very old Bluetooth devices may not work well with new phones or computers, and some cheap devices have weak radios.

Fix: Check the maker's website for compatibility and updates. If the device is old, it may be time to replace it.

11. Apps are fighting over the connection

Some apps, like fitness trackers, music apps, and headphone apps, try to control the Bluetooth connection. Two apps doing this at once can cause drops.

Fix: Close apps you are not using. Update or reinstall the app that goes with your Bluetooth device.

12. The device needs a reset

Headphones, speakers, and other Bluetooth devices can get stuck and need a reset.

Fix: Look up the reset steps for your model. Many devices reset by holding the power or Bluetooth button for 10 to 20 seconds. Then pair them again.

How to fix Bluetooth disconnecting on Windows

Windows has a few extra settings that often cause dropouts.

Stop Windows from turning off Bluetooth to save power

1. Right-click the Start button and click Device Manager.
2. Expand Bluetooth.
3. Right-click your Bluetooth adapter (it often has "Wireless" or "Bluetooth" in the name) and click Properties.
4. Open the Power Management tab.
5. Uncheck Allow the computer to turn off this device to save power.
6. Click OK and restart your computer.

Do the same for your Bluetooth mouse or keyboard under Mice and other pointing devices or Keyboards, if they have a Power Management tab.

Update the Bluetooth driver

1. In Device Manager, right-click your Bluetooth adapter.
2. Click Update driver > Search automatically for drivers.
3. Also check your computer maker's website (like HP, Dell, or Lenovo) for the latest Bluetooth driver.

Run the Bluetooth troubleshooter

Go to Settings > System > Troubleshoot > Other troubleshooters and run the Bluetooth troubleshooter. On some versions of Windows, it opens in the Get Help app.

How to fix Bluetooth disconnecting on iPhone

1. Turn Bluetooth off and on in Settings > Bluetooth.
2. Forget the device and pair it again.
3. Restart your iPhone.
4. Update iOS in Settings > General > Software Update.
5. As a last step, reset network settings: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This erases saved Wi-Fi networks and Bluetooth pairings, so you will need to set them up again.

How to fix Bluetooth disconnecting on Android

1. Turn Bluetooth off and on.
2. Forget the device and pair it again.
3. Restart your phone.
4. Turn off battery saver to test.
5. Update your phone in Settings > System > Software update.
6. Reset Wi-Fi, mobile, and Bluetooth settings: Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. The words may be a little different on your phone.

How to fix Bluetooth disconnecting on Mac

1. Turn Bluetooth off and on from Control Center or System Settings > Bluetooth.
2. Forget the device and pair it again.
3. Restart your Mac.
4. Update macOS in System Settings > General > Software Update.
5. Keep USB 3.0 drives and hubs away from where your Bluetooth device connects.

How to fix car Bluetooth that keeps disconnecting

Car Bluetooth has a few problems of its own:

1. Delete your phone from the car's list of paired devices. Cars can store only a limited number of phones.
2. Forget the car on your phone.
3. Pair them again while the car is parked.
4. Update your phone's software. Also ask your dealer if the car's system has an update.
5. Turn off battery saver on your phone while driving.
6. Keep your phone out of the glove box or center console, where metal can block the signal.

Choppy sound vs. a full disconnect

Sometimes Bluetooth does not fully disconnect, but the sound skips, stutters, or lags. The causes are similar, but a few extra fixes help:

• Close apps running in the background, especially games and video apps.
• Turn off Wi-Fi scanning or move away from crowded Wi-Fi areas, like coffee shops.
• Lower the audio quality setting in your headphone app if it offers one. High-quality modes need a stronger signal.
• Turn off features you do not need, like spatial audio or noise canceling, to test if they are the cause.

If the sound is fine near your phone but stutters when you move away, the problem is signal strength, not the headphones.

Quick reference table

The bottom line

Bluetooth usually disconnects because devices are too far apart, the signal is blocked or crowded, a battery is low, or a power-saving setting is getting in the way. Start by moving closer, charging both devices, and forgetting and re-pairing the device. On Windows, turn off power management for the Bluetooth adapter. Keep your software and device firmware updated, and most Bluetooth problems will go away.
