Dear 100 Hour Board,

When charging a cell phone battery, is it best to wait until the charge is almost gone to recharge it? Or, is it okay to charge the battery when it's not all that low?

I have been told that the battery will last longer and work better if I wait until the charge is very low and then plug it in to be recharged, but I do not like having to worry that the battery will go dead.

A: Dear The Beast,

Best rule of thumb: do what it says in the instruction manual for your particular phone.

In theory, lithium batteries (found in all but the oldest cell phones) can be recharged at any time without fear of losing their holding capacity.

Personally, I only charge my phone when it runs low. I'd rather play it safe than have to buy a new battery half way through my contract for more than I paid for my phone.
