I have one in my fitbit.

My wife invariably takes the charge down (on her laptops, tablet, and

battery in that state forever and some batteries last and some die
quickly (won't hold a decent charge).
I keep mine topped up and have no problems.

Thanks Rasta.
If I am understanding the table, the less the depth of discharge, the larger the amt. of recharges. Hopefully fitbit software does so. Would it be good if I recharged it when it reaches 50% capacity instead of letting it go longer?
Depth of discharge
Discharge cycles
(NMC / LiPO4)
Table 2: Cycle life as a function of
depth of discharge.* A partial discharge reduces stress and prolongs battery life, so does a partial charge. Elevated temperature and high currents also affect cycle life.
Note: 100% DoD is a full cycle; 10% is very brief. Cycling in mid-state-of-charge would have best longevity.
100% DoD ~300 / 600
80% DoD ~400 / 900
60% DoD ~600 / 1,500
40% DoD ~1,000 / 3,000
20% DoD ~2,000 / 9,000
10% DoD ~6,000 / 15,000

My insurance company gives me $1.50/day up to 100 days if I walk 10 minutes after each meal and complete 8000 steps per day. The possible $150 gift card is an excellent motivator.

Yes, to get more lifetime out of it, recharge when you see it's down
to 50-20% and try to recharge it to about 75-80% of full charge.
That's is what I'm doing with equipment with Li-based cells/batteries.
As Li-chemistry doesn't have the 'memory effect' topping up the
charge when not fully discharged doesn't have detrimental effects,
and both getting discharged to the minimum limit as well as beings
charged to its maximum and especially getting stored in these states
for a longer period are detrimental to the batteries' lifetime.
For longer storage a charge between 40-60% is best.
