Used it for 7 days after new and from use it will give me roundabout 8 to 10 days before charging. Lots of settings on, including notifications, connect, GPS only mode, about 1-2 activities per day with gps on, brightness 20%, gesture on after nightfall, custom watchface etc. Initially it showed me 22 days after full charge when I received it, but after updates today connecting with garmin express it settled on 28 days. So hopefully it will improve going forward. Coming from a Casio Protrek solar that lasted me 14 years without a battery exchange, it needs getting used to, but this watch is amazing for my needs so far. Got a 18cm (7 inch) wrist so think the 50mm would have been too big.
