Hello all,
So last week I bought a fenix 5. Store had it in open box and on the shelf but it was off, I was worried about it having been on for months on the shelf but they told me it had never been powered on, they only had the 5X on display powered up. Bought it, no discount got home and charged it. The battery was completely discharged.
One of my main reasons for buying the fenix 5 vs a 3 or another less expensive option was battery life - as I am starting to run ultra marathons.
Last Saturday ran my first. I started with 95% charge. GPS only mode (no Glonnass). I played occasionally with the watch during the race, and often moved it into view to see my HR (with backlight at 50%). Halfway into the race, 7 hours in, I notice it is at 40% battery. I changed it to Ultratrac in the activity settings menu, and start avoiding using the backlight or play with it(still glancing at it often to see HR).
My race time was 14 hours 30 minutes. When I made it across the finish line, literally 1 minute after, I glance at the watch to stop the activity and it powered down.
I know actual, realistic device times are often lower than what the manufacturer advertises. Still, advertised GPS mode at 20 hours and Ultratrac 60 hours, seems I should have gotten to the end of this race with a good battery reserve. I am planning longer races later in the season so... this watch might not cut it, apparently. My iphone 7 plus in airplane mode, but doing GPS tracking, went through all of this with 30% power left and me taking some pictures and listening to podcasts on the way.
So question to the group - is this the normal battery life I can expect from this device while tracking activities? Or did I get a dud or a battery affected by it being a showroom device?
Unsure if I am just being paranoid and need to enjoy the device and go Ultratrac from the start, turn off the backlight (not needed to be honest).
Thanks all,
Juan
