::I'm typing this on my 4S, please pardon any spelling or auto correct errors::
I've now spent three separate outings (two at the Apple store, one at Best Buy) with hands on experience with both phones. Total combined time, probably two hours.
On my first visit (Opening weekend of sales) I was convinced the 6 was for me. Perfect fit for my hand, great upgrade from the 4S and super fast. After reading more on the two phones however, I was REALLY excited about the larger battery the PLUS had. Being 6'5", the larger phone wasn't/isn't unwieldy to handle and extra screen real estate is obviously a plus. (pun intended)
So, what to do? Go to Best Buy and test them out again. At this point I was still going for fit, nothing to do with speed, that wasn't on my radar just yet. Both phones (at a glance) were incredibly responsive and snappy.
Later that night (this was last Monday) I ordered my PLUS, excited and confident. But, like any good nerd... errrr consumer, I continued reading. I had a nagging suspicion that the 6 (pushing fewer pixels with the same processor) had to be faster.
Article after article, benchmark tests, YouTube videos and comment sections... The hunt for info was on. This forum is/was the best place to post my findings and ask a question to those who may be more technically knowledgeable than I.
Went back to the Apple store today and did as meticulous and unbiased "tests" as I could. What did I find? The iPhone 6 IS faster than the PLUS, but we're talking mili-seconds. Frame rate discrepancies seem undetectable to the naked eye and the only time I could get it to "stutter" was coming OUT of spotlight back to the home screen. Furthermore! I only noticed the stutter because I was doing it directly next to the 6 while doing a simultaneous manipulation multiple times.
Here's the question, in iOS 8 unless you're being very picky, this isn't a deal breaker. Both phones are incredibly snappy and unless you're holding them side by side, you would never notice a difference. Question is, will further iOS updates begin to increase lag, latency and stutter on the PLUS or decrease it?
I use phones for as long as possible, hence why I'm still on a 4S.
Is the 6 PLUS a dud that is underpowered for the long haul or will it stay neck and neck with its smaller sibling?
Does FPS in opengl no longer matter with the introduction of Metal API?
Are current benchmark tests unable to accurately rate the new processor/GPU?
Does the FPS only matter when playing graphic intense games or will this eventually effect overall performance of the phone?
I this something software will fix, or is it another ipad 3 scenario?
My current "fears" are having me second guess ordering the plus and I would love to hear opinions from all of you.
Thanks!!!!
