FAQs
How much better is the battery life on the 47mm Fenix 8 compared to the Fenix 7?
The AMOLED model delivers roughly 60–70% more runtime (16 days vs. 9–10 days in smartwatch mode), while the solar MIP version jumps to 28 days (vs. 18 days on the Fenix 7). GPS mode with music also improves from ~10 hours to 13 hours on AMOLED and up to 90+ hours with solar.
Is the speaker and microphone actually useful, or just a gimmick?
Most users find it genuinely handy for quick hands-free calls on hikes or runs, voice-to-text replies, and off-grid voice commands (“start a trail run”). Call quality is clear in quiet to moderately noisy environments, though wind noise can reduce clarity.
Does the solar version still have an AMOLED screen in the 47mm size?
No, the solar option in 47mm (and 51mm) uses a transflective MIP display instead of AMOLED for maximum sunlight charging efficiency. If you want both solar and AMOLED, only the 51mm offers that combination.
Can I use the Fenix 8 47mm for serious scuba or freediving?
Yes, it is fully dive-rated to 40 meters (EN13319 certified) with dedicated scuba and apnea profiles, depth gauge, no-deco limits, and ascent rate alerts. It’s one of the few smartwatches approved for recreational scuba without an additional case.
