The only way a system with an AMD chip will ever see 9.5 hours of battery life is if it includes a car-sized battery. AMD's lowest power chips at best get 4-5 hours of battery life. None of its mid range or faster chips get more than about 3 hours. AMD is using marketing nonsense to buy time. If its Carrizo strategy was valid, they wouldn't be ending Bulldozer with the Excavator core. There are no genuine efficiencies possible with broken Bulldozer unless AMD can get off of last-decade 28nm node process.
AMD will miss this quarter. AMD will lower guidance for Q3, AMD will get hit with some more shareholder securities fraud suits, and then AMD will quietly exit existence and the pieces will be bought by various companies long after the shareholders have been wiped out and the employees sacked.
