I would like to ask for information. Why the battery is weaker with each update. I have the screen brightness set to low. Since yesterday I have not done any activity in which I would use GPS. Yesterday the watch charged and today I have only 48% Is this normal? A few months ago the battery lasted almost 7 days. There are also no changes like "nap detection" You can only set a given range e.g. 06:00-14:00 in which sleep is monitored but short naps during the day the watch no longer monitors. What puzzles me most is the battery life. Do you also have such experiences?
