inspired by the Mac who just introduced its new chip to prolong the battery life, this would be good if it can be applied for the phone as well. Most of people are carrying minimum one phone with extra power bank to avoid any unwanted situations when the phone battery cannot last. Why don't these phones company invent this dual battery in the back of phone since the size is getting smaller? probably it doesnt make any big different to the size for another extra one. Or it could be a form of chip that is placed in the slot as how the memory card was,and will be switched on after the first battery has died. however the challenge goes as it requires totally new design and to build this with the phone may cost it much up from the market price.
