With continuous heartbeat sleeping sp02, sleep tracking, WiFi, Bluetooth, lift to wake (occasional aod), around 1to 1 1/2 hour walk recorded a day (+ normal steps through the day), some calls/MSG's/notifications, emails etc, contactless payments. I get about 2to3 days, although I tend to charge it once a day or every other day at the most.
It's fully charged now and reporting 3 days 13 hours left in the battery section
About 2 to 3 days. Don't have WiFi turned on and tend to get a fair few whatsap, messages, calls and emails through. Wear it 24/7 apart from charging. I've a Duo charger so tend to stick it on every couple of days, charge up fully then that sees me through for next couple of days.
Its a shame withball the features bthe watch is capable of thatbwe have to turn most of limit to a dark/black watch face to conserve battery life. I am hoping samsung can provide some help with a new update
