an esp32 on an 1100mah battery will last years on deep sleep, and about a day with wifi on and in high power modes. a pixel watch 4 says they last 30 hours , ambiguously. they use a battery less than half the size. in reality with constant use they'll drop dead in 6 hours. the thing is clunky and heavy , anyway -- so if it lasts as long as an off the shelf watch who cares? also, the primary reason : lilygo shoves ESP…
Several Garmin watches last for weeks (24 days full charge, actual 1-2 weeks with heavy gps and fitness tracking), and I struggle to understand why consumers accept anything less. It seems like consumers don't realize what's available.
