@gkaempfer I see the conflict there. But keep in mind this is the advantage of a large battery. Suunto gives warranty for 1 year or 300 charging cycles (300 cycles is something you’ll get in 11 years! Based on a charging cycle of 14 days)

Influence of the low charge is equal. If you compare a battery which lasts 1 day or 20 days, and you drain both to 0%, the time below - let’s say 20% - is equal.
For the small battery it’s more frequent, but shorter.
For the bigger battery it’s less frequent, but longer.
So, I think keeping the battery healthy has more impact by draining it less than charging it less.
Also, I think a 14 day cycle is acceptable and most conveinient if you have a regulary week schedule. So if my battery is 20%, 16% or 14% - I don’t really care, and it’s still an acceptabel percentage to do a run
EDIT: by the way, I don’t think you should be worried about it too much. Probably calander aging is the biggest enemy and we just can’t stop time. The sweet spot would be 20 - 80% charge. But you’ll give up 40% of your capacity (that’s 8 days!) to keep your battery optimal for 20 or 40 years. That won’t happen
