The new, cheaper model of the iPad 2 has been found to have better battery life than its predecessor thanks to its smaller A5 processor, according to a new set of tests. Anandtech reports that the iPad 2,4—Apple’s internal reference for the new iPad 2 variant—offers significant battery life improvements over the prior iPad 2, with the increase ranging from 15.8 to 29 percent depending on the task.
For example, the iPad 2,4 was able to playback a 720p video file for over fifteen hours on a single charge, easily besting the thirteen hours of the prior model. Notably, there have been conflicting reports as to how big an improvement users can see from the revised iPad 2; prior tests showed a far smaller improvement over the previous version.
There appears to be no way to tell whether or not an iPad is a 2,1 model or a 2,4 model from outside the box, so consumers are currently left to guess as to which model they might be purchasing.
