Source: Christine Romero-Chan / iMore While I'm not a professional marathon runner or bodybuilder or anything like that, I have been trying to get more active in my life lately. Especially since my job involves sitting behind a computer for most of the day, typing away, physical exercise has never been more important. Even though I have one of the best Apple Watches, and it does a great job of tracking my workouts, it does so much more than that too. I mean, I get notifications and alerts, I use it for timers and alarms, track my sleep with watchOS 7, and even a phone call now and then. So as you can imagine, the battery on it can drain pretty quickly, especially when you factor in workout tracking with continuous heart rate monitoring.
