The Forerunner 55 boasts a two week battery life (smartwatch mode) and up to 20 hours in GPS mode, so you can spend more time on the go and less time charging.
That’s double the time in smartwatch mode, and an extra seven hours of GPS mode compared to the Forerunner 45.
Between workouts and daily use, the Garmin Forerunner 55 should last you over a week between charges, making it easy to wear all day long.
“I love how lightweight this feels. I put it on and pretty much forget about it until I start a workout,” says one reviewer. “It’s really easy to sleep in, and the strap is flexible enough to adjust easily without it sliding around.”
