Your strategy might work for you, but for me using a smartwatch that only had 30h of battery life was super painful. One of the reasons I use a smartwatch is for sleep tracking (+alarms/timers/flashlight/notifications), which means I can't charge it overnight and every day is too dynamic to always charge it at the same time. Plus I miss out on notifications and access to other features I use hourly when I put it on charge. With my Garmin and 2 week+ battery life, the first <15% battery warning still gives me 3 days to put it on charge or turn on battery saving and turn that into 5+ days which is plenty of time to find a convenient time for charging. I don't think it ever died on me due to low battery, unlike my previous smart watches. Ok, I lied, it died once on a month long trip, but a split USB cable and a hair tie let me charge it right back up. The low battery life might be ok if you do not use your watch for sleep tracking or alarms. Or flashlight. Gosh, I love my flashlight on wrist.
