  I think the more likely scenario is as follows:
  
  1. User looks at battery status in Plasma 5.16, sees "capacity" at 85%, and has no idea what this means, because it implies that the battery is 85% charged but this can't be the case as other stats conflict with this interpretation
  2. User updates to Plasma 5.17 and now there is "Degradation 21%". User now understands that this means their battery capacity is degraded. Maybe the string could be even further improved as "Capacity degredation:" as @meven suggested.
  
  At least, that's how it was for me. I did not understand what "Capacity:" was referring to until I started browsing the code. "Capacity" is an ambiguous and non-descriptive term that does not really communicate the concept we're trying to get across.
