Not Taking Care of Its Battery
Battery life is often a major concern for most smartphone, laptop or tablet users. But you could argue that it’s even more important on a wearable device that’s supposed to keep you updated and track your fitness and health.
So we recommend keeping your Apple Watch’s battery life in mind. Try not to keep it on the charger for extended periods of time (although overnight is fine). Also keep an eye on the temperature of your watch and its surroundings, since heat is one of the quickest ways to kill a lithium-ion battery.
