Yes and no. Leaving it on charge for a couple of hours will top it up
a bit more, and the charge capacity will increase after a few charge
cycles anyway. I'd suggest charging it overnight the first time, or
soon after the first time.

The thing about the 16 hour initial charge was true, valid and
important for NiCd and NiMH batteries, which consisted of several
cells wired in series. The slow trickle charge after filling the
battery was vital to top up all the cells to their maximum.

Modern handsets have Li-Ion or Li-Poly batteries that consist of a
single cell, so they don't need the long equalising charge.

However, it is possible that a long first charge might calibrate the
battery level meter more accurately - though I doubt it.

My Nokia phone won't allow that. It switches itself off before the battery
goes fully dead.

None of my recent phone manuals have mentioned this at all. They have all
stated: "Plug the charger in, and charge until the 'battery full' message
appears." - they then go on to provide instructions as to how to switch on
the phone, and enter a PIN, blah blah.

Fine, then go with that. All mine have stated to charge for 16 hours on
the first 2 or 3 charges and to ignore the phone's message saying the
battery is full, so that's what I do.

In other words, RTFM..!

Nokia already know, that's why they embed low volt limiters,
with temperature controlled overcharge regulators,
and short circuit protection into every battery,
all to make Li-ion foolproof

All the average fool can do, is dry out the cells by excessive
part recharging, shortening the batteries life.

I'm a 6310i diehard, can't be doing with these newfangled
all-singing-dancing-photo phones, I just want to make and receive calls..!
