I’ve had an AW0 for a couple of years, and had to charge it about every other day (my usage is apparently pretty light on battery drain). My AW3 LTE arrived Friday afternoon, and I put it on the charging stand while setting it up. Took it off the stand at 100% charge. It’s now Monday evening, a little over three days later, and my watch is showing 20% charge. This is after a lot of playing with the watch to check it out. I’m impressed.
