The 6+ has a larger, higher resolution screen which requires more power from the GPU, which in turn is powered by the CPU. When you start actually running content on this screen, you're going to need more RAM. Especially for gaming. If you think the 1GB that the 32 bit iPhone 5 with its smaller, lower resolution screen was packing is sufficient to give similar performance on the 6+ then you're entitled to that opinion.
Oh and by the way, nothing you have said thus far (or any videos you have posted) have managed to convince me that my 6+ doesn't reload tabs and apps for fun. It even reloaded this post whilst I was typing it! I went to reply to a Whatsapp message and when I came back to my post it reloaded, clearing my text. Fortunately I'm used to this BS now and copied the text before I went into Whatsapp.

You can't even swap between one app and two Safari tabs on the 6+ if you spend a minute or more in each.
So are you really saying that you were in Safari on this website, and only switched to whatsapp to reply and went straight back and you've lost what you entered so far in the reply?
Wow that is really not good, I can't say I use this website via the browser on my phone as I prefer tapatalk, but that is not good. I would suspect either a serious issue with your phone, or the coding of this website to be wrong and some event triggering, another could be network connectivity triggering an event to empty your content...However I would suggest something really isn't right.
And please don't go immediately that it is an inherent problem with the phone regarding ram as it isn't. Especially not for what you just described.

Exiting an app to enter another one is only "asking for reloads" if you are exceeding ram requirements for those newer apps. In other words, iOS dumps the memory (in this case from your tabs) in order to free memory for newer applications.
But... isn;t that exactly what this thread is about? I know it works that way. Others know it works that way. They are unhappy with the amount of ram given.
Unless I am missing something...
It is but it only dumps the memory of the 'oldest' 'least used application' (well a little bit more complex than that but you know what I mean). So in the example given of typing something into a tap, then switching to whatsapp to reply and switching back, neither app should be dumped. If that is happening that it seems they've only installed a z80 processor with 16Kb of memory
