If what you alledge is true, then why is the latest Samsung Note 7, still lagging behind last years iPhone 6s in real-world benchmarks? The iPhone 7, which drops tomorrow is "rumored" to exceed the iPhone 6s by anohter 35%. The truth of the matter is when you control both the hardware and the software; you can optimize the entire user experience; plus make it more secure.
As for security, there is no question as to who is more secure. When was the latest Android security update? Apple drops them every couple months, they are dropped within weeks of an exploit beind discovered - such that there is never truly a case of an exploit in the wild that really hits the iPhone. This is not the case with Android, and has never been the case with Android. Google mines your email, and your information with Android is open to anyone who wants to look. And that information is getting more and more personal as technology gets more advanced. Consider the latest health enabled watches. It won't be long before your company can tap into your watch and see what your pulse is doing as you walk. If the company is planning a RIF, and your pulse is showing you are not doing so well going up and down those hills; who is to say that this information would not be gathered?
With iOS, we know that this is not the case. The truth is that Apple makes it a paramount condition that privacy is not negotiable. They make money on their hardware, such that they do not need to sell your personal information to get money to supplement efforts to develop software.
If you are getting a service or application for free; don't kid yourself - YOU are the product. FaceBook, Android, Gmail are selling YOU to the hightest bidder.
Yes, the latest Note 7 is about 40% slower than the iPhone when pushing pixels. It also pushes 2.2 times as many pixels - that takes time.
On a pixel-time basis, the Note 7 is faster...
A far as security goes, I posted earlier. Both platforms have issues (only the most hard-core Apple fanatic would claim otherwise). By nature of being a more open platform, and one that is ~7 times more plentiful than iOS, it has more attack vectors put at it. Does that mean you’ll get infected? Well - I’ve been running Windows since 1991, and have had one confirmed infection in all that time. You won’t get a virus - you’ll get a trojan that fakes you out. Be smart and it’s a non-issue. But I guess if you need to have your hand held during operation then Android may not be for you.
As far as getting info from the user - Apple does as well. People forget they had iAds that was doing the same thing, and collected the same kinds of data for their own internal sales use (of course, Apple was really pretty bad at it, so they have closed it down). Apple - heck, ALL connected companies - collect data from users for their own marketing efforts - and will sell/share that as a whole when it best serves them.
Google doesn’t sell YOUR information to a particular advertising companies, they sell blocks of statistics, like “55% of our users are male; 84% who are interested in games are also interested in pizza”. You get aggregated into big groups. That’s the information you get as a consumer of Google analytics.
