It’s normal for most afaik but that’s because manufacturers make a trimmed down phone to go on your wrist which means you have to charge it daily, without realising it’s on your wrist so it doesn’t need to be super slim with huge cuts to battery size to go in your pocket.
My garmin has an always on display, heart rate, steps, blood oxygen, thermometer, barometer and whatever else and yet still manages a 4 week battery life, 3 weeks with normal use (1h gps per day, using the touchscreen and higher brightness) or even around 50-60h of GPS/more frequent heart rate/active maps activity tracking
It’s on 7% now and is giving me an estimated battery life of >2 days, which just shows how abysmal many smart watch battery lives are
