iPhones have long had a strong side that iPhones get iOS updates fast compared to Android. But now I see this as a weakness. Apple as a company makes money selling new hardware, so it has incentive to slow your old device down with each iOS update so that you eventually buy new hardware from which Apple makes money. Now whether the slow down of old devices is intentional or not is a different question. Maybe Apple only optimizes the new iOS releases for the newest hardware essentially making old devices slow. It's quite possible that Apple doesn't intentionally change the code for old devices to make them slow, they just leave them unoptimized. The outcome is the same. Whether it's intentional or a side effect doesn't matter, the FACT is a FACT and they do slow down your iPhone each year, despite Apple's claim that iOS 9 makes my iPhone 6 Plus faster. I have been Apple fanboy since the original iPhone and have always loved Apple as a company, because I saw it as an underdog and less evil than it's competitors. Now my opinion of Apple has changed completely, I have gone from loving Apple to disliking it. My reasons are as follows: There's absolutely no justification to release 16gb iPhone ($650) other than pure greed. They still include only 2gb of ram, probably to make your iPhone's lifespan shorter so that you will buy a new one sooner (Remember Apple makes money selling hardware) Apple copied Microsoft's idea by releasing iPad Pro and claiming to invent a Pencil and still managed to mock Microsoft for making toaster-fridge Apple have become too arrogant, always laughing at competitor's ideas and releasing half-baked, bug infested software themselves. Apple's PR machine influences most tech blogs by making them favor Apple regardless of what they release and downplay every single major flaws of its products. Apple tries to portray itself as less evil by always mentioning in keynotes that Google sells your data. On other hand Apple slows down your devices to make you buy new iPhone. No Google doesn't sell your data and for all intents and purposes Google is much less evil than Apple. In fact Google's moto is "Don't be evil". But here is the shocker, despite criticizing Google and telling you that you are the product, Apple also serves targeted ads! They call it iAds and you can read about it here https://developer.apple.com/iad/. In fact most free apps in iOS make money by serving iAds. Prominent examples that serve iAds are Speedtest.net, Arrow and thousands of others. And by the way, Apple keeps 40% of the ad revenue!! Now tell me who is evil? If you are still affected by the reality distortion field, now is the time to snap out of it. I have since moved to Nexus 6P, because I would hate to own iPhone 6S and have Apple slow it down next year by releasing iOS which supposedly makes it "faster".
