At night or when i get home from work and don't use my watch, i put it on airplane mode (to preserve iPhone battery life) and leave it on the charger until the next morning. of course throughout the evening and overnight, i get some text message notifications that I've replied to or have seen already, my iPhone also has a scheduled DND. ONLY when i turn OFF airplane mode in the morning is when i get a couple of text messages from the previous night after already seeing them on my iPhone and even replying to them. It's only text messages, nothing else. what gives?
