Fenix 5X Plus battery health

I just bought my Fenix 5X Plus at my local store. I asked them if the product has been in the store for a long time and they said no we just got them (Don't believe them actually...) The reason I asked that question is because of battery health. Batteri is supposed to be fresh(ish) and will degrade fast if they are left without charge for a long time.

When I got home and unpacked the watch, It was drained of course and I think it's been in the store for many months (not many people buy this expensive watch here in my town).

The question is: Do I need to worry about the battery? Will it perform or will the time it's been without charge degrade the battery? Should I return it? I just want this watch to last me several years and starting with a potential bad battery is not good.

I would not worry. The batteries don't really get their full capacity until 2-5 full recharges. But a tip - don't disconnect the moment battery says 100%. Leave it for 1/2 hour longer. That roughly gives me an extra day of battery. Garmin battery monitor % is not super "reliable" :)

But keeping track of battery life can be an issue. Install a battery monitor and a few of them require you (for best tracking) to open the app when you finish charging. Then you will get the best results.

When I train a lot (5-10 hours a week) i get about 0.4% power consumption average / hour - with zero training i'm at 0.2% per hour (both with PulseOx off)

But for the first few weeks you will probably have higher battery drain as you "use" more features for setup and learning.

Thanks Kaz911 and Geroelltrampel for excellent answers :) I will keep it and monitor the battery. Have 30 days to return if I find some problems.

One weird thing was that when I was charging it the first time, after several hours the charge was 60% and then I wanted to check something on it and then it suddenly just went from 60% to 100%... Is that normal?

Seems the battery is good enough. I've been on one hike and 2 long runs (with music also) and had the watch on for 4 days and still have 56% left of juice...

Same here. First time to charge my 5x plus. It went to 60 percent after around 1 hour up. Then suddenly when i checked it its 100 percent. I unplug it and my watch face says 60 percent.
