Re: phone ran out of battery hen refused to re charge up again
It is NOT good for these batteries to be totally discharged; it can damage your phone. The HTC ONE has a lithium-ion battery: See Below.

Hence, Ni-Cd batteries have to be completely discharged before charging again, to retain their full lifetime between charges. This is a peculiarity of Ni-Cd batteries, not shared by Li-ions. In fact, your lithium-ion battery likes it better if you donít discharge it all the way between charges. This is why Apple recommends that you go ahead and plug in your charger when the device gives you its low battery alert. When you charge, the battery doesnít really mind if you donít top it off. Li-ion battery lifetime is all about charging cycles. One charging cycle is the time between one full charge and one full discharge. You can partially charge or discharge your battery many times during a single charging cycle. In short, your lithium battery has no memory effect, and you can recharge it, in whole or in part, whenever you feel like it.
