• If you want to maximise battery life, then there are a few parameters: age, cycle count, charge level and temperature. You can't do anything about age and max charge level. Temperature in the watch should already be below 40C at all times (one would hope, being on your wrist!)

    The best thing to do is to not put the watch on the charger every night, but only when the level is low. That'll remove long periods of the battery being at 100% charge. Since the watch lasts for weeks before needing a charge, even a battery that loses 20% after only 200 cycles (a extremely conservative estimate) should still be good for years.
