Starting off with smartwatch-based battery life, the Forerunner 965 actually claims to get better battery life than the Epix. Again, this makes sense due to the tech being at least 14 months newer. In reality, the gap is even more than that. Garmin had been building and stock-piling Epix units for months prior to announcement. All claims backed up/exceeded during testing. The Garmin Forerunner 265 is said to last for 13 days in smartwatch mode, and up to 20 hours in GPS mode. The 265S lasts 15 days and 25 hours. These is dustproof and water-resistant. Garmin Fenix 6 Pro. Garmin Forerunner 945. The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water. sweat resistance. Garmin Fenix 6 Pro. Garmin Epix (Gen 2) — Could be described as a Fenix 7, but with an OLED screen, pricier than the Fenix 7; Garmin Fenix 7 (2022) — Garmin’s flagship watch, premium multisport GPS sports watch with on-watch maps and up to 18 days of battery life; Garmin Enduro 2 — Garmin's most advanced and expensive outdoor watch with premium features Garmin Fenix 7 and Epix battery life; Header Cell - Column 0 Fenix 7 Epix; Smartwatch mode: 18 days: 16 days (six days always-on) Battery saver smartwatch: 57 days: 21 days: GPS only: 57 hours: For example, the Garmin Fenix 3 lasts 20 hours with a 1-second interval, but for 50 hours in “UltraTrac” mode (a 60-second interval). A fixed, non-adjustable interval limits the ways in which the battery life can be extended, and — I would add — the watch’s applicability for long-distance efforts. While that’s not quite as fast as the latest gen Apple Watch units, it’s on the faster side of things for Garmin (compare that to a Garmin Fenix/Epix unit that takes nearly two hours). When it comes to real-world battery life, we’ll start with the battery specs from Garmin, and then go from there to what I’m seeing in the real-world.

Key considerations: 16-18 days in Smartwatch Mode; Up to 57 hours GPS battery / 23 hours Multi-Band Mode; Full maV96.
