I switched from Apple Watch to a Garmin Venu. The battery lasts for a week, and many of the sensors are more accurate.

And that's the fancy screen, gimmick edition garmin watch - the normal MIP display garmin watches (even an old, midrange Forerunner 255) will easily get a couple of weeks of battery life, more for the higher end ones.

OLED is just the wrong screen tech for these devices, never made any sense to me given how little I care about graphics and how little time I spend reading the display.
