Until we can leverage nanoparticles or carbon nanotubes in a cost effective way, it's tough to get any more juice. Battery technology grows in leaps as opposed to gradually. As the next 'better' battery components is discovered, capacity/charge rates/energy density leaps ahead. i.e. from Ni-Cd to NiMH to Li-ion to Li-poly.
Even the super high end Tesla Roadster only uses Li-ion batteries and it takes up like half the trunk.

I thought they fixed the OLED white issue by using RGBW instead of RGB to display white...as for energy saving..it actually is possible for OLED screens to act as solar panels..they had a few signs deployed which use 0 energy and just charge off solar power.
It may be just me but I think the future of portable devices lies in making cloth that is able to absorb heat and solar and wirelessly transfer the energy to the device. Maybe in 50 years >.>
