In April 2012, Apple started shipping a slight variant on the iPad 2 that remains for sale even as the third-generation iPad has become the mainstay of the line. This new version of the iPad 2 — labeled internally as “iPad 2,4” — uses a 32 nanometer version of Apple’s A5 chip that replaces the 45nm version in the previous iPad 2 model. The processing performance is the same, but AnandTech is reporting that the 32nm model has notably better battery life (and a lower manufacturing cost). Alas, there is no way to know if any given iPad 2 uses the new chip without running an app that reports on the internals. follow link
