I still have a iPad 2 with iOS6. Its battery lasts days, with the same duration for 6 years. All the old apps work fine. Only some ad-ladden websites crash the browser from time to time - but the same is true for all 512MB memory devices incl Android phones/tablets. The big mistake that many iPad 2-4 and iPad Mini 1 owners made was to upgrade to iOS7 (or newer) - well than it's game over, the UI speed degenerated a lot, and I know of no one of those early iOS7 upgraders that are still on their old device, many regretted "bricking" their device and bought a new device to replace the laggy thing.
