Battery reporting for wireless peripherals is kind of a hit-or-miss. Some expose their level to the OS, others don't. Even when they do, the data can be flaky enough to ignore. And Bluetooth devices tend to support it more than 2.4GHz ones.
Makes me wonder: is there a reference list somewhere of which devices actually work with #UPower? Would be handy to know before buying.
Could anyone shed some light for me on why Gnome Settings understands that a Logitech Unifying receiver mouse is a mouse, while the notification in the same system thinks it's a keyboard?
I wonder how many people have gone to the store and bought new batteries and thrown away the perfectly good batteries in their keyboards because of this, just to be annoyed by being greeted by the same message again next time they booted.

If anyone liked my idea, I made an issue for it and would appreciate a thumbs up :)
Please lower threshold for battery warning on peripherals
The secondary #battery of my #LenovoThinkpad #T460s was completely dead, which somehow confused the whole battery management and it just turned off after 3 minutes, even when the primary battery still had a sufficient charge left.
Replaced now both and after 3 full charge/discharge cycles for initial calibration, #UPower reports the secondary battery now at only 77% capacity left, which I'd expected after 500-600 cycles or so.
Where do those numbers come from? UPower itself? Battery internal?
And now, finally, eudev and upower are fixed!
