The basic steps to pair a new device
To connect a new device on Bluetooth, you need to put both devices into pairing mode at the same time, then select the device you want to connect to from the list that appears. The device you're connecting to (like a speaker or headphones) usually enters pairing mode when you hold down a button for three to five seconds — often until a light blinks or you hear a tone. The device you're connecting from (like your phone) enters pairing mode when you open its Bluetooth settings and tap "Pair new device" or similar.
Once both are in pairing mode, your phone will show a list of nearby Bluetooth devices. Tap the name of the device you want to connect to. Your phone may ask you to confirm a code that appears on both screens — just tap yes or confirm. After that, the two devices remember each other, and you won't have to pair them again unless you unpair them or reset one of them.
The whole process usually takes less than a minute. If it doesn't work the first time, turn both devices off, wait ten seconds, turn them back on, and try again.
Key Takeaways
- Put the device you want to connect to into pairing mode first, usually by holding a button until a light blinks or you hear a tone.
- Open Bluetooth settings on your phone or computer and select "Pair new device" or similar to enter pairing mode on that end.
- Select the device name from the list that appears, and confirm any code if prompted.
- Once paired, the devices will reconnect automatically when they're near each other and Bluetooth is turned on.
- If pairing fails, restart both devices and try again — most connection problems clear up this way.
Where to find Bluetooth settings on common devices
On an iPhone, open Settings, tap Bluetooth, and make sure it's turned on. You'll see a list of devices you've already paired with, and at the top you'll see "Other Devices" — any unpaired Bluetooth device nearby will show up there. Tap the name of the device you want to pair with.
On an Android phone, the location varies by manufacturer, but usually you go to Settings, then search for "Bluetooth" or look under Connectivity. Turn Bluetooth on, then tap "Pair new device" or a plus icon. You'll see a list of nearby devices.
On a Windows computer, go to Settings, then Devices, then Bluetooth & other devices. Turn Bluetooth on and click "Add Bluetooth or other device," then select Bluetooth. On a Mac, open System Settings, go to General, then Bluetooth, and click the plus icon to add a device.
Why pairing mode matters and how long it lasts
Pairing mode is a window of time when a Bluetooth device is willing to accept a connection from something new. Without pairing mode, any device could connect to your speaker or headphones without your permission, which would be a security problem. Pairing mode closes that window after a few minutes, so once you've paired your devices, they're locked to each other.
Most devices stay in pairing mode for three to five minutes if nothing connects to them. Some devices have a longer window — up to ten minutes — and a few will stay in pairing mode until you manually turn it off. Check your device's manual if you're not sure, but if you miss the window, just press the pairing button again.
What to do if a device won't show up in the list
If you put a device into pairing mode but it doesn't appear on your phone's list, the most common cause is that Bluetooth on your phone is off or the device is out of range. Make sure Bluetooth is turned on in your phone's settings, and move the two devices within ten feet of each other. Bluetooth works best when there's a clear line of sight between the devices.
If the device still doesn't appear, restart both devices. Turn them completely off, wait ten seconds, and turn them back on. Then put the device back into pairing mode and try again. If it still doesn't work, check whether the device's battery is low — some devices won't enter pairing mode if the battery is nearly dead.
Walls, metal objects, and other wireless devices (like WiFi routers or microwaves) can interfere with Bluetooth, though usually not enough to prevent pairing entirely. If you're having trouble, try pairing in a different room or away from other electronics.
Connecting to a device you've already paired with
Once you've paired two devices, you don't have to pair them again. The next time you turn on Bluetooth on your phone and the other device is nearby and turned on, they'll connect automatically. You'll usually see a notification or hear a tone when the connection is made.
If a device doesn't reconnect automatically, make sure Bluetooth is turned on on both devices and they're within range. If it still doesn't work, restart both devices. You can also "forget" the device from your Bluetooth settings and pair it again from scratch — this solves most reconnection problems.
Unpairing and removing a device
To stop a device from connecting to your phone, go to your Bluetooth settings, find the device in the list of paired devices, and tap the info icon or settings icon next to it. You'll see an option to "Forget," "Unpair," or "Remove" — tap that. The device will no longer connect to your phone automatically.
Unpairing is useful if you're selling a device, giving it away, or just want to stop it from connecting. It doesn't affect the device itself — you can pair it with something else whenever you want. If you want to pair it with your phone again later, just go through the pairing process a second time.
Bluetooth range and when devices disconnect
Bluetooth typically works within about 30 feet in open space, though walls and obstacles reduce that range. Most devices will stay connected as long as they're within range and both have Bluetooth turned on. If you walk far enough away, the connection will drop, but it will reconnect automatically when you come back into range.
If a device disconnects and doesn't reconnect when you come back, restart Bluetooth on your phone or restart both devices. Some devices also have a timeout feature — if they don't receive data for a few minutes, they'll disconnect to save battery. Turning the device off and back on usually fixes this.
Frequently Asked Questions
Why does my phone keep asking me to pair with the same device over and over?
This usually means the pairing didn't complete properly the first time. Go to your Bluetooth settings, find the device, and choose "Forget" or "Unpair." Then restart both devices and pair them again from scratch. Make sure you confirm any code that appears on both screens.
Can I connect one phone to multiple Bluetooth devices at the same time?
Most phones can pair with many devices, but they usually only connect to one at a time. Some devices, like car stereos and headphones, will disconnect when you connect to something else. A few phones support connecting to multiple audio devices simultaneously, but this is not common.
Is Bluetooth safe to use, or should I worry about someone connecting to my device?
Bluetooth is reasonably safe for everyday use. Pairing mode is designed so that only devices you approve can connect. Once pairing is done, other devices can't connect without going through the pairing process again. The main risk is if someone has physical access to your device and puts it into pairing mode without your knowledge.
What's the difference between Bluetooth and WiFi Direct?
Bluetooth uses less power and works over shorter distances, making it better for headphones, speakers, and watches. WiFi Direct is faster and works over longer distances, making it better for transferring large files between phones or connecting to a printer. Most devices use Bluetooth for everyday connections.
Why does my Bluetooth device keep disconnecting?
Disconnections usually happen because the device is out of range, the battery is low, or Bluetooth on one device is turned off. Less often, interference from other wireless devices or a software glitch causes the problem. Restart both devices and try again. If it keeps happening, unpair and re-pair from scratch.
