That's what I did with my old forerunners (the ones pre step counting haha). I went to fitbit for a year and a half (mistake) and then i got a fenix 6 4 years ago, and it still lasts for about a week and half with running/gps use every day or at least 5-6 days a week. We'll probably be on the 9 or 10 before the battery life gets down to unusable levels for me haha
