There are some other device classes to try for the -c argument: AppleHSBluetoothDevice AppleHSBluetoothHIDDriver AppleMultitouchMouseHIDEventDriver AppleHIDKeyboardEventDriverV2, they give different output. Ioreg -r -l -k "BatteryPercent" | grep -i battery any device with this property will be listed you need to know one of target device's property key(-k), for example it is BatteryPercent for Bluetooth keyboard and mouse instead of using device io class, you could also use a property key to query Ioreg -c AppleDeviceManagementHIDEventService -r -l | grep -i battery Ioreg -c AppleDeviceManagementHIDEventService -r -l the -c specify device class, the class could be specific or general by default some object properties are not shown the -l option is used to display properties for all object The solution that works on my computer is: // the -r option is used to reduce output On my iMac(macOS 10.12.6), none of solutions mentioned above works. Still unable to get the battery level from my headphones though, and not sure why :/ I know have a wireless trackpad & keyboard, and can see their battery levels perfectly fine ( in both the toolbar or the command line). (see screenshot below) 3 Look for the battery percentage level (if supported ) of your Bluetooth device (s) on the right side. 2 Click/tap on Bluetooth & other devices on the left side. I have a feeling batterypercent may only be coded for standard peripherals (trackpad, mouse, keyboard), as all battery monitoring widgets I've tried are only compatible with such devices. Here's How: 1 Open Settings, and click/tap on the Devices icon. The Battery Level can be read using the GATT Read Characteristic Value sub-procedure, so I need to figure out a way of interfacing with this service from the command line. Looking at the Bluetooth docs, it seems there's a Battery Service which exposes the Battery State and Battery Level. Just can't figure out how to access the batterypercent param. Initially I thought the issue was with the device name, but it seems "Powerbeats Wireless" and bluetoothaudiod work interchangeably. How can I check the battery level of my bluetooth connected headphones? Please note that Windows 10 can show the Bluetooth device’s battery level only if the device supports this feature. This means that, you get the exact battery level status of the external Bluetooth device. This leads me to believe that the device is broadcasting battery level, and that I should be able to access this information from my computer. Windows 10 RS5 build 17639 and later builds show you the battery level of your external Bluetooth device. If I connect the headphones to my iPhone, the battery level immediately pops up on the toolbar. I tried ioreg -c bluetoothaudiod |grep -i battery to get general information about the battery, and get this as a response: | | +-o AppleSmartBatteryManager I tried this command using "Powerbeats Wireless" and "bluetoothaudiod" for the 'deviceName''s, but neither returned the batterypercent. Ioreg -c 'deviceName' |grep -i batterypercent I came across a few discussions, and it seems all I need to do is enter the following: What this means is that Google is now going to make it possible for Android to display a percentage from 0 to 100 for a supported Bluetooth device.Ĭheck out the source link for a more technical breakdown of what was found in Google’s APIs and source code and when you can expect to see it on your Google Pixel or Nexus device.I am trying to check the battery level of my wireless headphones from the command line. Google has added a new “method” called “getBatteryLevel()” as part of the “BluetoothDevice” class. Every time I switched back to the Huawei Mate 8 I was using at the time, I would lose the ability to see how much battery I had on my Bluetooth headphones.Īccording to a report from XDA-Developers, Google is finally including support to get battery information from a Bluetooth device in an API that would be part of a future version of Android, perhaps Android 8.1. I used to use a pair of Jaybirds X interchangeably with an iPhone 6S and some other Android phone. That is the Bluetooth device battery life indicator. With most stock versions of Android, there is one missing feature that has been seen on other factory skins of Android like OnePlus, LG, and Samsung.
