Just because it doesn't affect you or you don't use some features doesn't mean it is not relevant to comparisons.
Somethings are just puzzling for people to parrot because of tech blogs filled with people who know little of the technical side.
For the love of technology-loving and understanding geeks stop saying it isn't comparable because of OS. They're using the same ARM architecture on a custom wafer, however it's using the same hardware technology already available. There is nothing on an iPhone that is not on another wafer's technology or wouldn't work on another phone. IT IS comparable.
Back on topic:
Apple doesn't document or alert you that you shouldn't have more than 5 tabs open on safari unless you want constant refreshing nor they document software related restrictions. It's safe to assume that the iPhone 6 should be capable of multitask, but fails to do so well as well as the competition.
I think it's beyond discussion when Apple's own diagnostics marks memory usage at 100% as a problem (red) and was the reason for replacing my phone.
To add to the safari I also have webpages refreshing in the same instance that I use safari, as I may have 7 tabs or more open. I switch between tab and tab, and it refreshes despite me just using that tab 2 minutes before (all without minimizing, or switching apps).
Another example of hardware nerfed is NFC which is Apple pay only, on the tech specs of the iphone 6 and 6+ they do not mention that limitation.
I feel like Apple does really well for what they use and in some uses they are better than the competition, but they also have some potentially serious flaws due to hardware limitations they purposefully make.
I can be pretty realistic and non bias when it comes to looking at the products I use and know largely what cons and pros exist for the iphone. And if I don't I can understand why it's happening. I don't think pointing out flaws in a product or anything one enjoys should be taboo or met with resistance.
Imagine if we practiced this mentality for politics. We'd been a tyranny decades or a hundred years ago.
