Replacing my 6plus with the 6s and iPad mini 4, a great combination. Always thought the 6plus would replace the mini, but did not really fit the bill.
I did with 6 Plus -> 6. Definitely.
While 6 Plus (and hence 6S Plus) does have bigger screen, it was never comfortable for me to use it as a normal phone.
Regular 6 just feels right in my hand. 6 Plus was kind of more than a phone, but still no match for an tablet: every single time on a couch I preferred the iPad to it. Every single time, when I was on a go, I wished it was smaller and handier...
I really could evaluate both for a longer period of time, because I ordered my wife a regular 6. At the end I was alway jealous of hers.
So 6 and now 6S are the perfect matches for me. The only missing thing from 6S Plus is not even its resolution, but the Camera OIS.
My wife uses an iphone 6 and will get the 6S. When I had the Plus, it meant we couldn't really share the same car mount or accessories. Plus was pretty uncomfortable to use after a few minutes. Fits in pocket ok and can carry around. But just not getting any benefits from the larger screen to compensate for the bad ergonomics of the device.
Things look better but it's just not comfortable to use. It lagged, stuttered, and the lack of RAM constantly shows itself in shutting down apps and reloading safari tabs.
OIS doesnt really mean much. I haven't noticed much of a difference with it. Of course the battery life is noticeable but you can get around that. Perhaps if the Plus had something else going for it. A built in stylus or more exclusive iOS features. If the iphone 7 Plus can get a native resolution screen, smaller size, and better features for its size, then I may give it another try.
In the end, it's just a phone. The smaller the better IMO. I only used the Plus for a month before selling it and going back to better performing and MUCH more comfortable to use 5S. But I look forward to the 6S.
That's exactly what I'm doing too. I really like my 6 that I've had for a year. I want to try the 6S plus to see if I like it better. I will return it for a 6S if I don't like the portability. I wish Apple made a 5" 1080 screen.I'm going the other way this time around. I've has the 6 since launch last year and I pre-ordered the 6s Plus this time. Figure I'll have 14 days to exchange it if I can't get used to it, but thought I wanted to give the bigger one a go and see what it's like. We will see...
Haven't enjoyed the size at all. Too big for my hands / pockets.
Won't miss OIS either.
after reading the reasons to go back to the 6 I'm glad I have 14 days to try it.
