I have had the Instinct Solar, for 5 days. The battery life is exceptional, 3% battery depletion in every day, even when using the GPS for outdoor activities ( running), and about 3 hrs of solar charging. I had the instinct, and upgraded. The battery holds true, about 83% in five days. Also love that it pairs with my Inreach mini, I conserve battery by using the battery saver power mode when sleeping, but configure it to allow sleep tracking , and heart rate. Which are important to my usage. I trust it as a part of my equipment for hiking. Love that there is , an ABC , GPS solar watch that is reliable.

I have had two different FitBit watches and the Galaxy Watch and the Galaxy 2 Watch. The Instinct Solar is my favorite. I like that it is easy to read in all conditions. I am particularly pleased that with the accuracy and consistency of the heartrate monitor, which is quite important to me. I also like that I can turn off the things I have no interest in using like text notifications and phone calls. I just use the watch as a watch and a fitness tracker that is it. That is all I want. The battery life is terrific. I don't know what the maximum life is, but it is way over a week. It has been over a week since I charged it last and it is reading that I have 11 days left.

The Garmin Instinct Solar might not be the most attractive multi-sports watch around. but it just might be the most practical, with incredible battery life thanks to its Power Glass lens, which keeps it topped up in daylight.

From the dial to the strap, Garmin Instinct smartwatch is absolutely rugged and shock-proof. They are not afraid of external adversity due to the moisture-proof shock-resistant case and sensors. The watch has built-in flagship activity trackers.

Backcountry fitness junkies take note, the Garmin Instinct Solar has more data than you will ever need, and enough battery to go the distance (as long as you’ve got sun).
