If you tend to spend most part of the day indoors, a solar watch may not add much in terms of battery life to your smartwatch. Therefore, a Fenix 7 Solar is an ideal fit for someone who is outdoors for a major part of the day.

Unless the Fenix 7 Solar gets adequate solar exposure, solar charging may not add much in terms of battery life.
