The Apple iPhone 6s and iPhone 6s Plus Review
I wonder, how many years iPhone 6S will be able to stay relevant. For example iPhone 4S started lagging on iOS 7. While it's certainly usable on iOS 9, it feels as an old and underpowered device.<p>If you have powerful computer from 2010, it'll happily run Windows 10 and almost any application, including almost any game in medium (or even high) mode. I wonder, whether this race on mobile platform will continue or iPhone 6S will be able to run iOS 15 without any lags?<p>On an unrelated note, I really don't understand, why iOS 9 (actually iOS 7+) is so slow on iPhone 4S. I was able to run powerful 3D games on that phone. Like a lot of shaders, triangles, special effects, and so on. This phone actually has good enough GPU. Why simple sliding animation could lag? Why opening "Settings" app takes few seconds? That's crazy. Probably there are good technical reasons for that, but I just don't understand, what they could be. Sometimes I think that there is intentional performance bottlenecks for old phones, so people would want to buy a new ones. I has the chance to compare iOS 6 and iOS 8/9 on the same phone, and difference is huge.
