I reckon we may actually give up on batteries and use carbon nano-tubes to make high-capacity capacitors. These would last nowhere near as long as a battery or hold as much charge but capacitors can get fully charged up in seconds so you would just maybe see people charging 5 times a day but maybe 30 seconds a pop.
Additionally, I see a lot more wireless charging based on inductive charging and also harvesting ambient RF energy in the air.
Clearly all phones will be really powerful and will have ultra-high speeds. 3D hasn't taken off yet on phones but it may do. We will also see flexible phones with flexible displays.
