Has any mobile phone company thought of an idea to add a DC capabilities to any new brand of cell phones?. Why am I asking?. Most of the time the mobile phone can not run without a battery inside. Unlike laptops,which you can use the laptop without a battery. The reason I wish mobile phones get a DC adapters is that, sometimes the phone battery becomes really hot while charging and still using the phone. Sometimes we need to make important things with our phones but battery is dead. With direct Current, the phone can be plugged into the outlet and use the phone even without a battery. I am aware that charging phone and using it weakens the battery. Introduction of this technology of using phone just like a laptop can save us a lot of issues.
