    Is it true that it's good for the battery if you fully charge the cellphone the first time you charge it. If so then why? If not, why is it recommended?

    For lithium-ion batteries, which almost all cell pones use now, there's no need to charge it fully the first time you use it. Li-ion batteries don't have a 'memory' to them them like Ni-Cad batteries do, where crystals would begin to form if it was left at half-charge for long periods of time without frequent complete discharging and recharging.

    One thing that will kill a Li-ion batteries life is quick chargers... which are most of the typical car chargers out there.
