Battery life not greatest I turned off auto wifi that made a difference but I train 5 days a week so it usually lasts about two plus days that's not using the phone on the watch very often as well, feel a bit let down......!
Just received my pre ordered galaxy watch so far a lot to take in, but 1 issue is the lake of battery life I charged it Sunday night took nearly 3 hours! Just had to charge again Tuesday morning another 3hours. It's the 42mm version.
