Generally cell phone batteries would be drained in about 10 minutes if these programs were to run on these little devices. Even when on mains, they'd probably fry and melt in the next 10 minutes. The CPU gets quite hot with these intense and hours long jobs. Finally, like the X360, PS/3, GPUs there are no sciences actually designed to use these devices. They may be in the far future when it is predicted that cellphones/PSA's are thought to have Desktop Computer power, but still the power will be an issue, lest a truck battery could be shrunk to a 1x.05x0.1 inch size.
