Why can't a mobile be more like a cordless kettle?

Yeah - but we measure phone batteries in terms of milliamps, so it's sort of not worth caring about...

You can measure any current in milliamps but it's also true to say that most phone batteries are multiples of a thousand milliamps, otherwise known as multiples of an amp. My phone battery is 4300mAh - also known as 4Ah.

How many wireless phones do we expect to see being charged? A million? Ten million? Even one milliamp becomes one thousand amps if a million devices are drawing that current.
