As in the question, I've established the max performance point worth paying for (that I'd notice) in a non gaming desktop (and the brands of all the parts are good quality, PSU also taken care of). I'm now wondering what would be the max point in cores and ram for a mobile phone (for my usage and that I'd actually notice)? Cameras I'm assuming are fine above 7MP, and I need to be able to change batteries and increase storage. I want fast standard operations as with a desktop like scans, boot up, browsing speed, minimised lags, etc. Like my desktop, I plan on keeping the mobile for a while and don't see me getting a new one unless I have to. Apologies if parts or all of this are off base, this is my first time shopping for a smartphone. Realistically, it will be android because I don't think the iPhone is worth the premium for my needs. I have gravitated towards Samsung (although I've never actually purchased one yet) but I'm open to others for performance and price. I'm sure there are brands with similar or better specs/prices that I've never heard of. For example, I had never heard of Xiaomi till a few weeks ago.
