NAVO W1 lasts more than two full rounds of golf on a single charge, with up to 12 days of standby.
Use the magnetic USB charger included with NAVO W1. Align the charger so it sits flat on the back of the watch before plugging in.
A full charge is best done before a round. If you are storing the watch, top it up every few weeks to keep the battery healthy.
Avoid charging in extreme heat or cold and keep the charging contacts clean and dry.
