oh i agree with you and everyone else about the battery issue. but to me, mobile cpus/gpus/apus/*whatever*us have come a long way pretty quickly.
I agree. I just hate that they've jumped into the gaming hardware bandwagon rather than pushing a more obvious form of optimization. My old phones would last days before needing a charge. New phones last around 10-16 hours. That's a huge step backward in terms of their actual purpose. There is so much technology available these days, phones with similar power to what they had 4 years ago could be streamlined to generate less heat and use less power.
Mobile gaming isn't the primary function of tablets, but PC gaming isn't the primary function of PCs either. Battery life has been steadily improving along with graphical power, so it's not like they're ignoring that issue.
PC's can be built with that as a primary function. Phones and other mobile platforms cannot (at least not yet). A computer does what you make it to do. A phone/tablet is what it is and the fact that the manufacturers are blurring their purpose means that they are going to become riddled with features and stuff they don't need, driving up their price and preventing the consumer from seeing productive improvements and price drops as quickly as we should.
I'm not saying that they haven't improved anything, they certainly have. But today's smart phones could be a lot simpler and have a much, much longer battery life than they currently do if the focus was to minimize power consumption in the hardware/software rather than to beef up the power.
