It looks like the difference might be between the HR and non HR versions. Or the 20 h number is an error.

Serious Style That Stands Up to the Roughest Conditions
fēnix 3 style
fēnix 3 is available in 3 bold models: gray with high-strength, scratch resistant, crystal and black band; silver with red band; and the premium sapphire model with a stainless steel band and sapphire lens. Each watch features a protective stainless steel bezel and buttons, and reinforced housing for extra durability. A sunlight-visible high-resolution color Garmin Chroma Display with LED backlight lets you access your data in any light. fēnix 3 is water rated 100 meters and has a battery life of up to 50 hours in UltraTrac™ battery saver mode,
16 hours in GPS mode and up to 3 months in watch mode (all depending on settings).

Up to 40 hours in UltraTrac mode; up to 16 hours in GPS training mode; up to 2 weeks in smartwatch mode (with 24/7 HR monitoring)
Again, it's not unreasonable to expect that both use the same engineering to save power (unless there's a good reason not to).
