Not clear from the photos is the batteries' physical dimensions, which is said to have caused a great deal of pain for Apple in the run-up to manufacturing. The company is thought to have had trouble when attempting to slim the parts down by some 30 percent, a reduction reportedly required for the design of Apple's next-generation handsets.
At least one report from earlier this week suggested that Apple may have solved that dilemma, though the company said to have come through with the solution is Taiwan-based Simplo Technology.
