For years I used a Mi smart band to track my exercise. It said a 30-35 minute session on a stationary bike burned around 250 calories which roughly agreed with what the bike said.
I recently switched to a Galaxy Ring and the Samsung Health app says that same workout burns over 500 calories. Every single resource I can find on the web says biking burns around 500 calories an hour so the band was right and Health is showing twice what it should.
