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

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.

I personally don’t think you can go wrong with a Garmin. I have a Fenix 6 Pro and have to charge about once a week after running 4 times a week. I’ve had it for going on 3 years too so they definitely last. Doesn’t have the same smart features of say an Apple or Samsung watch but that would be my recommendation

Fenix 6 Pro owner here. Can't upvote this enough. Garmin has excellent battery life, supports a ton of different sports, and is a generally excellent piece of kit.

I use fenix 8 solar, previously had fenix 6 pro and fenix 5 before that. My wife has venue 3. All are excellent. I use HR strap for when I care about HR. Fenix 8 has probably the best sensor from all the farmins, but still a 50$ strap is more accurate. I have no experience with forerunner series. Heard some good stuff, but I dont know what models are better than the others. I would really look at the amazfit rather than an entry level garmin now. $500 amazfit trex is very close to my $1000 fenix.
