clip-on tuner

Hello guys new member here! anyone know how to determine if your prs clip-on tuner is fully charged? I own the one that shows eagle on the center. Sorry idk the model type. Your answers would be very much appreciated. Thanks!

I was excited about the PRS clip-on tuner when it came out, since many don't fit the headstock super great. The rechargeable aspect seemed cool, but WOOF does it not hold any charge. I was expecting something like the Apple TV remote where you charge it every few weeks and then can ignore it...

The beloved PRS headstock isn't the most generous for extra room around the tuners. My clip-on tuners barely hold and are tight against the tuners. Yeah, I know, not a big deal but out of curiousity and wanting to buy a new clip-on tuner for no good reason, is there a tuner out there that fits...
