Larger screen equals worse battery life?
In that case: Keep it, thanks.
Actually it would probably be the opposite. Large screen equals more area for a bigger battery. At the very least it would be the same battery life but quite possibly could make the battery life even better.
LTE is going to be the real battery life killer in the new iPhone which is why I believe they will have to put in a large screen, they will need as much battery space as they can get.
I am curious how the battery life is on the supposed test iPhone 4s with the a5x. Seems like it could be a lot of phone on a pretty small battery especially if it has LTE on it already.
As for the mock ups, those are definitely not Jony Ive designed so its hard to get a good feel for would the new phone could be. But I certainly expect the next redesign to be a pretty major one.
