Which is better: Recharging a device after it has absolutely no electricity left left or after it still has a tiny bit left?
My dad kept telling to recharge my MP3 player only after it automatically shuts down due to the lack of electricity. His reasoning is that all of the old electricity should be used up before a new supply is given. I doubt that's good for the device.

Normally, that will make no difference, though I'd personally be reluctant to let things have to turn themselves off. However, the Battery University (http://batteryuniversity.com/index.htm) is a far better resource than I am.

Hi does your dad drive a car ? If yes then ask him if the same idea apply to car too ? Does he wait until the fuel tank is empty and the car cannot move before he top up new fuel ? Idea is old fuel must be used up before a new supply is given isn't it ? :D

LOL, makes sense.

With the latest generation of rechargeable batteries and devices, many specifically recommend to not let them completely discharge. While it's true that many of the earlier generation of batteries held their charges better if discharged, if not completely, close to completely; most of the newest batteries do not share that trait.
Best answer, of course, is to see what your owner's manual says (or check the manufacturer's web site).

Yes, it does make sence. Because combustion and stored electronic energy operate in similar fashions! :p
The man above me is quite right. This was the norm, for older batteries, but dell, rim, and many other electronic device companies still recommend fully draining batter after first charge.
I think of batteries more like muscles, not car engines. Batteries, like muscles, have memory, of sorts. Draining them fully will allow them to be rejuvenate better the next time (like working out, work to failure).
Thats just my two cents. I'm no expert, but thats how I was taught! and i've never really had battery issues with anything (except my cell phone as i charge that way too often, in the car, attached to my laptop)

I actually heard that the battery is somehow electronically "calibrated" from the first full charge until it fully drains so that it knows exactly how full it is. I would think that an improperly calibrated battery could maybe send the device a "shut-down" signal before the battery is fully drained, or not allow it to fully charge maybe? I am no expert either but I just thought I would share my input.
Well, manufacturers suggest you recharge your device after running out of electricity, in that way you are making the battery live longer, than if you charge it when it have still energy.
