I have a garmin fenix 6 pro and it’s underestimating my calories daily by about 200. According to the watch data and tracking every morsel of food religiously, my weekly deficit is ~2200 calories. I’ve lost between 0.5-0.8kg/week for the last 4 weeks. That means my real deficit is over 3500 calories per week. Every BMR/TDEE calculator does the same, underestimates for me. I barely exercise and get about 8000 steps per day at work. 1400 cals a day, 5ft 3 and currently 149lbs

💯 I waited to upgrade my 6s Pro, which was seeing significant battery decline, until the fenix 8 came out. No 8s with MIP, max battery life of like four days?? Ended up buying a 7s Pro at a significant discount and it’s drastically better than the 42mm version of the 8.

Fenix 6X PRO. Was a new open box item in John Lewis and marked down to £276 about 3 years ago. I’d been looking at an instinct and then saw this and jumped on it. Can’t fault it.

I have an AWU3 and just grabbed a Fenix8. How do you mix their use? Do you use the garmin for sleep? If not, how does that change your training load? I had a fenix6pro that I used for a couple 50k’s, and I want to get back into doing them. That’s why I picked up the 8.

Hola, pasé del fenix 6 pro al suunto race, y lo hice porque el altímetro empezó a fallar al año, pero bien exagerado, el servicio técnico de Garmin es una vergüenza, se llevaron el reloj y me dijeron que todo estaba bien, obviamente para trailrunning si las métricas de desnivel acumulado no son buenas, no sirve de nada. Suunto en GPS y altímetro no tiene rival, todos los días la misma ruta y clava las pendientes, el ascenso guiado es muy bueno también. Si buscas algo fiable, para mí no tiene rival en ese aspecto, outdoor TOTAL. Si buscas guías de entrenamiento, música, pagos con el reloj, etc... chorradas varias pues Garmin no tiene rival, y en cuanto a Coros, veo mucha copia de Garmin, podría ser una mezcla entre Garmin/Suunto. En cuanto a la medición del pulso, una cinta siempre, absolutamente siempre, será mejor. En cualquier reloj. Llevo 6 meses con el race y ahora no sé si venderlo y pillar el vertical 2. 🫣🫣, ¿qué me recomiendas?

My Fenix 6 Pro is 4.5 years old and still runs great.  Battery capacity is going down but I still get > a week. Best way to make your Garmin have a long life is to not charge it daily and avoid charging it past 80% on a regular basis.  Same as with a phone.
