Yeah, I know the drill I struggled with this for ages myself. It was especially frustrating when using multiple devices at once headphones, a keyboard, a gamepad and having no idea how much battery life they had left. Windows really lags behind in this regard. Eventually, I scoured a bunch of forums and found a decent solution this website. It has a utility that does exactly what the system is missing: it shows the exact battery percentage, displays it in the taskbar, and even sends notifications https://workstation-master.com/bluetooth-battery-level.html It’s convenient that everything happens automatically; you don’t have to go into settings every time. Plus, it supports various devices; it detects both my headphones and my controller just fine. I’ve been using it for several months now it works without any issues.
