** Hmmmmm .... try
" Lithium polymer battery lifespan" in Google
Might just work ....

?Don?t you see that whatever enters the mouth goes into the stomach and then out of the body? 18But the things that come out of a pers on?s mouth come from the heart, and these defile them. 19For out of the heart come evil thoughts?murder, adultery, sexual immorality, theft, false testimony, slander.

I'd suggest professional help, but religious delusion is a hard nut to crack. But take heart! all is not lost; your batteries can last forever if you just have faith and pray.
Phil has some sort of mental disease. Seriously. And he may be deluded. Pray for him.
** See anything wrong with my post above ???
Anything at all.
**The serious metal case is YOU - pal.** Better if brain dead, trolling scum like you had been aborted
- seriously.....
FOAD you revolting prick.

It depends on your battery management, when you keep it charged between 80% and 20% you will about double the lifespan compared to always charging and discharging it to its limits.
Good info can be found here:

I think it's got more to do with voodoo and divine intervention.
My wife invariably takes the charge down (on her laptops, tablet, and phone) to the point where the screen can't stay on, then leaves the 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.
approx 6 months in an aircraft, 20 years on the shelf.
how long do you plan on carrying that thing around?

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
I would like to carry it around as long as possible.
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.
