Di2 question

[BrazAd]

I bought a late ‘21 S-Works Roubaix a couple of months ago. It has 9100 Di2 11-speed. My question is regarding charging and the battery.

I have charged it for -hours-. The battery symbol on my Wahoo Roam looks like it is about 90% charged, yet the next screen says it is only 60% charged.

No matter how much or how many times I charge it, it never goes beyond 60%.

Bike has about 8,000 miles on it, fwiw.

Is the battery wearing down? Or is the display reading inaccurate?

Any ideas/tips/suggestions are welcomed as this is my first time using Di2.

Thanks,

Gary
