Troubleshooting

This FAQ topic applies to all classes of Bluetooth devices. If you are having a problem with audio devices (including headsets, headphones and speakers), please check another FAQ topic first.

  1. Make sure that your Bluetooth device is paired to the computer where Bluetooth Battery Monitor is running
  2. Turn off your Bluetooth device and turn it back on
  3. Many Bluetooth devices don't report their battery level frequently. Toggling device power usually forces such Bluetooth deices to send the report and helps Bluetooth Battery Monitor to show the information.

  4. Check if your Bluetooth device is capable of reporting its battery level
  5. Bluetooth Battery Monitor is not a magic program. It relies on each Bluetooth device to report its battery level.

    If you have a smartphone that can show Bluetooth devices' battery level (iPhones and many new Android phones can), please try with it.

    You can also find "rule of thumb" battery level support in the other FAQ item – Does my Bluetooth device have a capability to report battery level?

  6. Still having a problem?
  7. Please contact us using the contact form. Please make sure to include the following information.

    • Name of the device as it appears in the Windows user interface.
    • If you have verified the device's capability of reporting battery level and, if so, with which smartphone.
    • If you are willing to help us by collecting additional information if it is necessary.

Bluetooth Battery Monitor requires Bluetooth adapter of your computer to be in the active (working) state to:

  • Properly install the software.
  • Recognize the new Bluetooth devices.
  • Get the up-to-date battery level of the Bluetooth devices.

If you see the warning message about disabled Bluetooth, please turn on the Bluetooth adapter with the following steps.

1. Click the Action Center icon located on the right-hand side of the taskbar. Click the Action Center icon
2. If the buttons are collapsed and the Bluetooth button is not shown, click the Expand link. Click the Expand link
3. If the Bluetooth button is gray, it means Bluetooth is turned off. Click the button to turn it on. Click the Bluetooth button
4. When the Bluetooth is on, the Bluetooth button is highlighted. Button is highlighted when Bluetooth is enabled

Bluetooth Battery Monitor relies on each Bluetooth device to report its battery level. But, not all Bluetooth devices have that capability. Device manufacturers usually do not advertise this feature either. As a result, when a device is not recognized by the program, it is hard to tell which to blame – device or program.

This FAQ item provides "rule of thumb" about Bluetooth device's battery level support so that you will be able to decide which to suspect in case of a problem.

Phones, Tablets, PCs
These devices do not report battery level via Bluetooth.
Audio devices (such as headphone, headset or speaker)

Battery level information is communicated through Hands Free Profile (HFP). Most Bluetooth audio devices support HFP, but some (such as speakers or Bluetooth to analog converter) do not support it, hence no battery level reporting for them.

Bluetooth Classic HID (Human Input Devices – such as keyboard or mouse)

If your HID device is a Bluetooth Classic device, the chance that it reports battery level is not so good. Bluetooth Battery Monitor's anonymous usage data shows that only 10 to 20% of HID devices report battery level using well-known method.

It is also known that some major companies (namely Apple and Logitech) use proprietary method to report battery level. Current version of Bluetooth Battery Monitor does not support them, but future version might do.

Update: Starting version 1.3.0, Bluetooth Battery Monitor supports most of the Logitech keyboards and mice.

Bluetooth Classic Game Controllers

Technically, game controllers are the part of the HID devices and there is a well-known method to report battery level. If your game controller uses that method, Bluetooth Battery Monitor should be able to support it automatically. But, so far, we have not seen any Bluetooth game controller that uses well-known method.

Sony Dualshock 4 and Microsoft Xbox One controller do implement proprietary methods to report battery level. Starting version 1.3.0, Bluetooth Battery Monitor supports Dualshock 4 controller. Xbox One controller support might be added in the future version. If you are interested in Xbox One controller support, please contact us.

Bluetooth Low Energy (Smart) Devices

Generally speaking, you can expect much better battery level reporting support with Bluetooth Low Energy devices. Most Bluetooth Low Energy HID devices (such as keyboard, mouse and pen) do support battery level reporting.

In addition, unlike Bluetooth Classic devices, Bluetooth Low Energy devices have a definitive way to check its battery level reporting capability.

  1. Open device manager.
  2. Select View menu > Devices by connection
  3. Locate the Bluetooth LE device in question in the tree view
  4. Look for the Bluetooth LE Generic Attribute Service node(s) under the Bluetooth LE device node. (Fig.1)
  5. If there is no such node, this Bluetooth LE device does not report battery level.

    If there are one or more such nodes, repeat the following steps for each node.

    1. Double click the node to open its Property dialog box.
    2. Select Details tab.
    3. Select Hardware Ids property.
    4. Check if the Value contains ...{0000180f-... (Fig.2)

    If you find a node with ...{0000180f-..., this device can report battery level.

Bluetooth audio device can make two types of connections to the other device (such as computer or phone). One is A2DP (also known as "headphone", "music", or "media audio") and the other is HFP (also known as "hands free", "headset", "voice", or "phone audio"). In addition to voice audio data, HFP transfers battery level information (while A2DP cannot). So, even if you are not using the device for phone calls, you need an HFP connection between your device and this computer to monitor battery level.

By default, Windows enables HFP for Bluetooth audio devices, but if Bluetooth Battery Monitor's Troubleshooter led you to this FAQ topic, it's disabled in your computer. Please follow the steps below to enable it.

1. Right click on the Sound icon in the taskbar and select Sounds from the popup menu. Then select Playback tab.

2. Right click on the device list area and enable Show Disabled Devices option and Show Disconnected Devices option in the popup menu.

3. Look for Headset or Bluetooth Handsfree Audio (or similar name) icon for your Bluetooth audio device. (Black down arrow means the device is disabled) Then right click on the device and select Enable in the popup menu.

4-1. If the black down arrow on the icon disappears and the icon is not grayed, it's ok. You may or may not see a green mark on the icon, but it's ok either way.

4-2. If the black down arrow on the icon is replaced by a red down arrow, it means Windows tried to establish a connection but for some reason it failed.

If this is the case, please continue to the other FAQ topic – How to connect disconnected HFP connection

Bluetooth audio device can make two types of connections to the other device (such as computer or phone). One is A2DP (also known as "headphone", "music", or "media audio") and the other is HFP (also known as "hands free", "headset", "voice", or "phone audio"). In addition to voice audio data, HFP transfers battery level information (while A2DP cannot). So, even if you are not using the device for phone calls, you need an HFP connection between your device and this computer to monitor battery level.

Windows, by default, tries to make HFP connection automatically, but sometimes it fails to do so and you need to fix it manually. If Bluetooth Battery Monitor led you to this FAQ topic, please follow the steps below.

1. Right click on the Sound icon in the taskbar and select Playback devices from the popup menu.

2. Right click on the device list area and enable Show Disabled Devices option and Show Disconnected Devices option in the popup menu.

3. Look for Headset or Bluetooth Handsfree Audio (or similar name) icon for your Bluetooth audio device. (Red down arrow means the device is not connected) Then right click on the device and select Connect in the popup menu.

If you see a black down arrow on the device icon, it means that the HFP connection is disabled. If that is the case, please complete the steps in the other FAQ topic – How to enable HFP connection first.

4. If the red down arrow on the icon disappears and the icon is not grayed, HFP connection was successfully established. You can stop here.

If you still see a red down arrow on the icon, please continue to the next step.

5. If the previous step failed it means that your Bluetooth audio device is refusing to establish a HFP connection with this computer. This usually happens when the device can make only one HFP connection at one time, and it is already connected to other device (such as your phone and/or tablet).

In such case, please try the following.

  1. Temporarily disconnect your Bluetooth audio device from other device(s) (such as phone). You can do this by disabling Bluetooth radio of the other device or putting the other device in the Airplane Mode.
  2. IMPORTANT: Just turning off the screen of other devices doesn't stop them from using Bluetooth.

  3. Toggle the power of your Bluetooth audio device and let it reconnect to this computer.
  4. The red down arrow should disappear by now, but if not, please unpair the audio device from this computer and re-pair it.

These steps should allow this computer to establish HFP connection with your Bluetooth audio device. For more information about how Bluetooth audio devices handle multiple connections, please see the other FAQ topic – Audio device problem when it is paired to multiple host devices.

Turn off Bluetooth radio (Andoid)

Turn on Airplain mode (Android)

If you pair your Bluetooth audio device with multiple host devices (phone, tablet or computer), you may experience problems with getting the device recognized by the Bluetooth Battery Monitor. This FAQ explains what causes the problem and provides possible workarounds.

Bluetooth audio device makes two sets of connections between itself and the host device. One is phone audio connection, which is mainly used for phone calls. The other is media audio connection, which is used for video and music. Important thing you need to know is that battery level information is communicated only through the phone audio connection. So, even if you are using the audio device only to listen to music, you need the phone audio connection to monitor battery level. Sometimes audio device establishes only media audio connection and leaves the phone audio connection disconnected. This causes a situation where "Bluetooth audio device looks connected, but Bluetooth Battery Monitor doesn't recognize the device or update the battery level".

Things are simple if your computer is the only host device that your audio device is paired with. In this case, no one else involves in the connection process. Occasionally Windows may fail to auto-connect phone audio connection, but you can manually fix it by the method explained in another FAQ.

But things get more complicated when your audio device is paired with multiple host devices because whether phone audio connection can be established depends on the connection capability of the audio device and the status of the other host device.

Let's look into the details based on the connection capability of the audio device. You can find which capability your audio device has in its manual (usually in the paring section).

  1. If your audio device allows to be connected to only one host device at a time.
  2. In this case, your audio device is either connected to the computer where Bluetooth Battery Monitor is running (Fig.1) or connected to the other device (Fig.2). If the latter is the case, you need to manually disconnect the audio device from the other host device and reconnect it to the computer where Bluetooth Battery Monitor is running. When the audio device is reconnected, Windows may fail to auto-connect the phone audio connection, but it can easily be fixed by the method explained in another FAQ.

    Fig.1 Audio device is connected to the computer where Bluetooth Battery Monitor is running

    Fig.2 Audio device is connected to the other device

  3. If your audio device allows phone audio and media audio to be connected to different devices.
  4. In this case, in addition to the two cases explained above, your audio device may be connected to the both host devices at the same time (Fig.3).

    Fig.3 Audio device is connected to the computer, but phone audio is connected to another device

    This pattern of connection can be useful if you want to listen to the music from your computer while you are waiting for a call from another host device. But, if you choose this setting, your computer cannot get access to the phone audio connection. If you try to connect using the method explained in another FAQ, it simply fails (you cannot enable "Headset" for the audio device). As a result, Bluetooth Battery Monitor cannot recognize the device or get battery level from the device.

    If you don't use the audio device to make/receive phone calls through the other host device, you have two options:

    • Manually disconnect the entire audio device from the other host device, or
    • Configure the other host device so that it will not connect to phone audio.
    • If you do not use the phone audio connection to the other host device, you may be able to disable the phone audio connection. Once you set up this way, your computer can always get access to the phone audio regardless which host device grabs the media audio.

      Fig.4 Disabling phone audio connection — Android example

  5. If your audio device allows simultaneous phone audio connections to multiple host devices.
  6. This feature is called multipoint (Multipoint explained - Blog @ Jabra.com ) and some (usually mid-range to high-end) devices implement it. If you are lucky enough to have this type of device, your audio device can establish phone audio connection to both devices (Fig.5) and you can get everything without sacrificing anything.

    Fig.5 Connecting with multipoint capable device

    Just like any other case, Windows might occasionally fail to auto-connect phone audio connection. If it happens, please fix it with the method explained in another FAQ.

Starting with version 1.12.0, Bluetooth Battery Monitor allows users to manually refresh battery information. But, this option may not be available or may not work in several cases including:

If these are the case, please try to turn off the device and turn it back on. Doing so will usually force the device to report its current level.

Also, please be advised that there's a good chance you will get the same battery level data when you manually refresh it. Many devices have coarse battery level indicators and it usually takes a very long time to change.

These devices usually do not report their battery information and, to monitor them, you need to install software on them.

Windows PCs
Please install Bluetooth Battery Monitor to the PC you want to monitor.
Android Devices
Please install our free companion app Bluetooth Battery Reporter from the Google Play Store.

IMPORTANT: To monitor these devices, you need Bluetooth Battery Monitor version 1.10.0 or newer.
