Both are premium GPS smartwatches, but new features make fēnix 8 a better choice.

If you’re thinking about buying fēnix^® 8, you’ve come to the right place.

You might also be considering a fēnix 7. Before deciding, you need to know about the differences between the new fēnix 8 Series and the fēnix 7 Series of GPS smartwatches.

You already know fēnix is the premium multisport GPS smartwatch. You know it’s the premium adventure watch, thanks to its lengthy battery life and rugged design. You know you can trust it during your outdoor recreation activities.

We’re going to compare the fēnix 8 Series to the fēnix 7 Series so you can choose the best watch for you.

New display options

The fēnix 8 series offers a bright AMOLED display or a solar charging display with a memory-in-pixel (MIP) screen. This means you can choose between a brighter screen or longer battery life.

The fēnix 7 series also has a transflective MIP screen that’s visible in sunlight. It does not have an AMOLED option.

The fēnix 8 – 47 mm AMOLED premium smartwatch also offers a bigger display at 1.4” compared to 1.3” on fēnix 7, as well as a higher resolution with 454 x 454 pixels compared to 260 x 260 pixels.

Improved solar charging

Battery life will vary depending on which version and size you buy, with larger watches offering longer battery life and enhanced solar charging taking your battery even further.

fēnix 8 – 51mm provides 50% more solar power than its predecessor, lasting up to 30 days in smartwatch mode or up to 48 days with solar charging¹.

fēnix^® 7X Pro – 51 mm, Solar Edition will last up to 28 days in smartwatch mode or up to 37 days with solar charging.

The consensus? The fēnix 8 series battery will last longer.
