Is it mandatory to "drain" battery for cycling?

I got a new iPhone 5S recently, and I've heard you need to drain the battery and let it die completely after charging it fully. Is this really necessary? Or does it even make much difference?

I've also heard it's bad for the type of batteries in an iPhone to get below 40%? True, or does it matter?

No just use it any way you want.

Just use your phone and enjoy it, plug it in and charge it when necessary.

On older Li-ion batteries you could shorten the life if you ran them down to 0% often. I'm not sure if this is still the case, but I don't make a habit of it.

It will be fine...it does affect your phone but will not be noticeable for about 3 or more years-by then u will probably have a new phone. Just use your phone and don't worry...I used to worry about the battery too but it won't affect u for a couple years so u will be good.
