So the PSP slim DOES have a longer battery life...kind of.

@ Shams, they cut the power usage of the psp, so it generally has the same amount of battery life if used on the slim psp, but if you use the original psp battery you have 12 hours instead of 6.

 You have 8-10, not 12, and that 8-10 hours (just like the DS 15-19) is with everything set on the lowest setting.

I really dont think the average psp life on the current psp is 5 hours, my psp last around 7 and a half hours with full lighting and volume.
