in real life, if you are serious about the processing power,
( i.e. demo to customer SQL server running on notebook / quarter management meeting )
you don\'t make it with battery power.
thus, so many young kids talking about 續航力 is joke only.
in serious usage, you are in meeting room in starbucks in airport lounge .......
using battery only and let the cpu run on lower speed
is child-play.
