Seems the 4 and 6 are the least impressive upgrades from a performance perspective. It also seems that aside form those two, healthy gains are usually seen


Also. it is comforting that iOS9 works on a 4s.....a MAGNITUDE slower than the 6s. That may mean that iPhones are safe for upgrades in years to come
 
Im coming from the 6+ to the 6S+. Got the phone on launch day and am still really really impressed with the speed of this thing. Everything is blazing fast.
I agree.

I guess we also have to consider that iOS 3, iOS 6, and iOS 9 are like the "perfected" forms of each iOS design. iOS 4 changed several design elements and iOS 7 did even more so.

It seems that iOS is also on a strange three year cycle: iOS 1, 4, and 7 were the "radical" changes, iOS 2, 5, and 8 were the "feature" releases, and iOS 3, 6, and 9 were the "stable" releases.

I have to disagree with that. I used the iPhone 6 for three months and the day I got the iPhone 6s, I immediately noticed the speed, memory, and smoothness improvements.

you noticed memory? did you run multiple apps at the same time? or 10 browser tabs at a time? or it is your head telling you that it got 2GB?

come on man. hardware spec these days is more than what people really need on mobile devices unless you do serious gaming or 4K which are not what iphone is for anyway with its tiny screen.


if you have a PC with Intel i5, upgrading to i7 does not do you any good if you just use mail, text, browsing the web.
i7 only matters if you play games, video editing, photoshop, etc.

so yeah, stop exaggerating and misinform others.

but still a whole lot less than the 4s to 5s jump.....

the 5s continues to be a beast
The 5S was pretty lame actually. It had an incremental CPU hike which was barely noticeable in the real world and a jump to 64Bit. Oh and Touch ID, but sadly it kept the same amount of RAM as the i5. As a 64Bit device uses more RAM than a 32Bit device the dreaded browser and app reloading made an appearance. The woeful iPhone 6 & 6+ milked the paltry 1GB of RAM even further with their bigger screens. I would put the iPhone 5 before the 5S. In real world terms it had more RAM than the 5S, i6 and 6+. I wish I had kept mine and jumped straight to the 6S+ for a proper across-the-board upgrade.

Did I mention specs anywhere in that post? No. Is that computer analogy really applicable to smartphones? No.

I am not exaggerating and misinforming others. I have used both phones and am providing my personal experience with them for others to read. If you have also used both phones, then by all means please post your own personal experiences with them, but don't say that I'm exaggerating and misinforming without knowing what I've personally seen by using both phones. You're not a mind-reader, after all.
 
I have to say I haven't been a fan of the iPhone's released last year. I felt that they went backwards with speed and feel of the phone with the 6 and plus.

Now I have a 6S and wow this is what the 6 should have been. Speed stability screen colours battery it's all here. Finally a phone that I can use for the next 2-3 years.

So well done apple finally a iPhone we deserve.

The iPhone 6S is a win. Apple really has made a great device. It's a bit heavy, but other than that, the best smartphone ever made.

you said you noticed "memory". it sound like spec to me. normal people use their phone as a tool. they don't feel "memory" like geeks who like spec.

based on your logic, those who still own iphone 4 and 5 are suffering with lag. iphone 4/5 are useless?

Yes, I noticed apps reload much less frequently and so do websites when going back in Safari. That is not a spec. A spec would be me saying the iPhone 6 only has 1GB of LPDDR3 RAM while the iPhone 6s has 2GB of LPDDR4 RAM (and I did not mention that).

"Normal" people do not care about specs, but some people who might read my post might find it slightly informative even if you don't.

I can't speak for others (unlike you), so I don't know if the iPhones 4 and 5 suffer with lag, and I would not say that they are useless, but I wouldn't have if I wanted to since you put those words in my mouth.
 
I understand you just got a new phone and are still in exciting mood. but you are acting like 6s is far ahead of 6. based on Apple paper, A9 is just 30% faster than A8. you can barely tell the difference in real usage. 2GB RAM does not improve speed. it is just more memory used for multi tasks or tabs in browser. phone iOS is not really multi tasks anyway. you often run one app at a time anyway.

Where are you getting your info from? You are sorely misinformed. The A9 is 70% faster in the CPU and 90% faster in the GPU.

I also upgraded from the iPhone 6+ to the 6S+ which I received on launch day. I find performance to be substantially better across the board. Everything I do on the phone just feels so much smoother than the prior generation. I have also not had one crash of any app or webpage, which is a huge change from the 6.

It's clear to me that the last generation was pushing the very limits of the 1GB of RAM (hence the app and web page crashing), and the CPU was not able to drive the 1080p display at the smoothness we've come to expect from an iPhone.

This new hardware solves all those problems in a major way. The CPU is faster, the GPU is faster, there's twice the RAM (probably 3x the available RAM to apps), and the interface between the RAM and CPU is far better too (see Anandtech).

When I browse the web on this thing, it feels like using a desktop PC. You can NOT say that about the prior generation.

YouTube comparison videos don't really depict this difference well. It's not about the total number of seconds for a webpage load. It's about the smoothness of the whole experience of the lack of crashing, plus the ability to retain websites in memory.
 
The iPhones 3GS, 5, and 6s are the three iPhones in which you could actually notice the speed difference between them and their respective predecessors. This is probably because these three iPhones are the only ones that increased both speed and RAM at the same time.

Coincidence that they fall three years apart? If not, then expect the iPhone 8 with 4GB of RAM to be the next speed demon.

I just noticed my i upgraded from 3gs to iPhone 5 to 6s. lol
 
I agree the 6S is awesome and better than the 6 with the ram and little better camera. But is force touch really that great? I saw some jailbreak tweaks awhile back I think that did kind of the same thing on the home screen and it just doesn't seem that exciting to me. Oh and the speed. Let's have somebody do a video comparison of an iPhone 6 running 8.4.1 vs the 6S running the latest iOS 9. I'm betting with a lot of basic tasks and even with web browsing and opening apps these devices will be very very similar. How do you make lighting fast faster?!? You slow down the 6 on iOS 9 and optimize the 6S for the latest software. I bet the 6 holds its own (running 8.4.1) vs the 6S. I'm keeping my 6 on 8.4.1 and it's great and super fast. I couldn't stand the lag of iOS 9. Sure my safari web pages reload boo hooo. I'm happy with my 6 until the iPhone 7 comes out.
 
Still getting used to remembering to use force touch, though the keyboard trackpad mode is a huge advantage. If you're going to use any aspect of force touch, use that one. Once you learn the technique for it, it's very slick.
 
3D Touch really is such a game changer. In 8 years (since the whole touch/multi touch concept started) it's the first attempt anyone has made to add how you interact with the content and the actual screen.

You can dive right into a task or area of an app without even having to open it, manually navigate to that specific task. In a years time when a ton more 3rd party app devs update or rewrite their apps to take advantage of this outside and inside their apps, it's truly going to be amazing.

Also peaking into emails or content without having to go in and back out, removes the need for multiple taps (into and out of.) This saves time and is more natural. (Just might not feel natural to some quite yet because it is totally a new concept)

3D Touch is a whole other league above Force Touch (and probably why it got a new name.) We are just seeing the very beginning. Future iOS 9 major updates might expand on it, but it's almost guaranteed iOS 10 will be adding to it quite significantly. For now it's in the hands of 3rd party devs to be creative and come up with ways to really take advantage. This is where it's going to be an "ahh ha" moment for many.

Yeah I feel like 3d touch is a forward thinking feature that maybe we don't realize right now apples plan for it. I remember reading comments similar when Touch ID came out. Yet here we are, it's basically engrained in most smartphone users lives, across different oems. If Apple has been working on this for 4-5 years like rumored I bet they have a big plan for it, more than possibly we can see right now.
 
I'm also one of the people who upgraded from the 6 Plus to 6s Plus you can literally FEEL the difference all the lag in graphics on iOS 9 are smooth on this device. The 2GB of RAM and the 1.85GHz processor are a huge leap for me. I'm a heavy user and I can honestly say; everything has improved. This iPhone feels like it can survive a few iOS updates and not slow down. Compared to the 6 Plus which slowed down some with iOS 9, that Spotlight lag actually did get to me.

This doesn't make any sense, the A7 was powering the iPad Air which has a much much much higher resolution display. The A8 does perfectly well at 1080P (which is shown by Apple putting it in the new Apple TV, which will primarily drive 1080p screens). I don't feel like my 6+ is slow, although the ram constrains are obvious, if anything it's the ram that is crippling the phones and not the processor. Although I do turn off the iOS 9 graphics in accessibility, maybe it's that crap which is slowing down your phones.

The Apple TV doesn't render at a much higher resolution and then downscale down to 1080p. Plus the A8 in the new Apple TV is (A8 Second Generation) which is not much but a bit more powerful. (About 5-10%)
