If you buy through a link here, the store pays me a small commission. Your price stays exactly the same. How that works.

My short take

Apple rates the 46mm Series 12 at 24 hours, or 38 in Low Power Mode. Macworld ran its own battery test and got 51 hours on the first run, then a weaker second result. It only pairs with an iPhone 11 or later.
