Worse and better on the iPad 2The spindly fonts and delicate elements of iOS 7 only make the non-retina-ness of these screens more noticeable. This is an OS built for screens without visible pixels. As we noted in our iOS 7 review, a switch in the accessibility settings can beef up the thickness of the fonts so they don’t look so pixelated.Fortunately, iOS 7 does actually seem to improve the browser. The new OS handily bests iOS 6.1.3 in SunSpider, Kraken, and Google Octane. The incessant, overeager page refreshing seems to be less of a problem, and the pages don’t take as long to loadThis is not great, but may not be a big deal in my house:How much battery you get out of an old device like this will depend on if you've kept it in good shape and which settings you have in use at the time. For a quick battery test, I set my iPad 2 at 50 percent brightness and had it cycle through a handful of webpages to simulate browsing. On 6.1.3, the iPad managed about 10 hours 11 minutes of life, while on 7.0 it got about eight hours and 55 minutes. An hour and 15 minutes is a pretty sizable difference, so if battery life is of utmost importance to you, upgrading may not be the best idea.
