My phone gives me charge load for my bluetooth headset why wont my mac? [duplicate]

Solution 1:

I hate to have to answer in the negative but the answer is: you can't.

Only apple devices exchange this detail via Bluetooth today.

The only vendor I’ve seen that has third party software to expose battery level is Logitech. I can’t recommend the software though as it has more downsides for me than upsides.

I've done a lot of searching the web, testing utilities, playing with ioreg on the commandline, scrutinizing System Profile reports, and it appears to me that OS X has no way of displaying battery level of connected devices that don't automatically display battery status in their Bluetooth menu Device submenu, even if iOS devices display detailed level info for the same Bluetooth device when connected to them. OS X just appears to completely ignore this capability in all but a few default (Apple-manufactured, it appears to me) devices.

Solution 2:

The battery indicator for headsets does not appear on the Mac, regardless.
