Another question. What if I found a used iphone 6 or 6s, still on ios 9. Could I restore from backup onto the other phone (keep in mind my iphone 6 now has 11.2.6 on it now..

If you still have an iOS 9 backup, yes.

However, if you’re going to buy another device I highly recommend you take the upgrade to a 6S. I came from a SLOW 6 Plus and got upgraded to the 6S Plus by Apple (had touchscreen disease and the system let them upgrade me for the same price) and the difference is astonishing. This thing works as smooth and quick as the 6 did on iOS 9 (better to be honest). I actually like iOS 11 now.

Oh, crap, my backup with ios 9 is many months old, so I don't really want to go back and loose all that info...

Hmm, maybe a 6s would be a good idea.

I have a friend was has a 5se, he only uses it for music mainly, and has no aps, and just a few text message threads. It's lightning fast on ios 11, crazy fast. He says that's because there's basically nothing on it.

The SE is the same chip as the 6S. Yes, it’s defintely a lot faster. The CPU isn’t all that much faster than the 6 but the RAM is double the size (from 1GB to 2GBs). I believe that makes all the difference as iOS 11 has a lot going on in the background and less RAM swapping to do which slows things down.

Plus you’d get 3D Touch which is more useful than people say. I use it to peek at links and move the text cursor many times daily. That and the camera is 12MP instead of 8MP and is faster which is very useful in real world day to day usage.

I appreciate the great info. Maybe I can pick your brain a little more. My Iphone 6 that was on ios9 was jailbroken, and went it updated to Ios 11.2 jailbreak was lost. That's fine with me I guess, but all that data from the jailbreak and jailbreak apps is still hogging up hidden space somewhere right? I didn't gain any space, so I assume I could have wasted gigs from jailbreak apps that had videos, etc in them?

This iphone 6 has also been restored from an itunes backup through the last 3 phones I've had from many years ago. I keep hearing to do a fresh install, which I don't want to do as I have thousands of text from business clients with attachments in them that I cannot lose and photos in camera roll. Is there a way to save all text messages with attachments and everything in camera roll and put it to a new phone with the structure intact with texts and attachments in the message threads?

Yes for photos but unfortunately no for messages.

In iOS 11.3 (currently in beta) Apple finally has messages sync in iCloud but that won’t do you any good on 11.2.x.

However, any backup will not include your jailbroken app’s data so don’t worry.

Thanks again. so, for me, I can't really do a clean install, until after 11.3 is out? Then I could sync to icloud for messages?
 
Interesting.

Thank you again, and at the suggestion of many people on here, I bought a used iphone 6s (2 gig of ram, 128 gig ($225) and now the phone runs as fast as my iphone 6 did on ios 9, actually it's much QUICKER! Unreal. What crazy is, iphone 6 has 1 gig of ram, iphone 6s has 2 gig, iphone 7 2 gig, iphone 8 2 gig, and iphone x has 3 gig. All the difference was in the ram! Also, 6s adds 3D touch, and adds the raise to wake feature, not on the 6, that works great with "hey siri".

So, if you have an iphone 6 on ios 11, get a used iphone 6s for cheap and the phone will FLY!

(some things I noticed with the 6s vs 6 is the vibrate isn't as strong, I'm assuming apple may have changed the vibration to be less than the 6, which was crazy loud)

It’s actually a completely different technology. They added the Taptic Engine in the 6S (same that the Apple Watch uses just bigger). It’s a lot more accurate than the one in the 6 so haptic feedback is possible.

The CPU in the 6s is MUCH faster than the 6

There's a huge difference in the A9 vs A8 and I'm not referring to benchmark specs solely. The actual design is enhanced. There's a reason it's almost twice as fast as the iPhone 6, ram is only one aspect of performance. The cpu and GPU in the 6s are huge upgrades over the 6.

It is more accurate to say the 6 is not much faster than the 5s. The A7 and A8 were very similar.

Thanks, interesting again and cool to know and understand.

1) so, is the 7 and 8 really that much faster than the 6s then? I think I heard 7 isn't much faster than 6s. When my 6 updated to ios 11, it crippled it and most said just get a used 6s (that's what I did) and it's amazing now!

2) I'm currently on 11.2.6 on this 6s and am a hard user for work. I may get 200 texts a day easy. Hasn't anyone with a 6s gone to 11.3 and did to slow or speed anything up for basics of mail, texting/pics, etc?

No worries!

1) on paper (benchmarks) the 7 is a fair bit faster (notably single core) and the 8 is much faster (notably multi core).

However in real world, the speed is negligible. They are all “limited by the speed limit on th highway”, that is the apps that use this power.

One needs to put the A9 into benchmarking perspective first: it still outperforms many laptops as a chip, including Apple laptops which run macOS high sierra smoothly.

A lot of people who visit these kinds of sites enjoy spec comparisons and having the latest and greatest product may compare the benchmarks but the reality is from a practical standpoint, you will not see any notable speed differences between the iPhone 6s to 7 to 8. It’s all related to the core design and core specs between these three devices.

The core tasks these devices handle are not performance hungry and the base specs on different levels (cell radio and band support, wifi with mimo, lpddr4 ram etc) are all identical. Especially for text messages or making phone calls, the A9 is way more than enough power. It’s the most future proof chip Apple has thus created. You’ll notice “premium” features on the 8 vs the 6s but from a purely practical perspective, you’re getting the same experience. The A10 and A11 from a performance perspective are very powerful chips and unless someone *wants* to upgrade, you absolutely don’t need to. Gone are the days where two generations apart - the iPhone 3GS to 4S or 4 to 5 - were major upgrades. Simply because of the advances in the chip tech, reaching a certain point. The A9 is an incredible chip and it set the foundation for the high performance cores in the A10 and A11. The really processing demanding tasks are GPU related and even then few apps push the gpu in the A9, and nothing “chokes” it.

2) iOS 11.3 really does speed up the iPhone 6s. Partly because it is a stable release and partly because it focuses on performance and the throttling issues that have been well publicized. If you are experiencing any performance issues, it’s purely related to the battery. I have 11.3 on a 6s I use for betas and developer related items and it is buttery smooth. For fun I compared opening apps and things to my mother’s iPhone 7, still running iOS 10 and they are more or less identical in performance (fluidity, opening apps, 3D Touch, etc) though iOS 11.3 is a bit faster due to the quicker animations. I highly recommend upgrading to 11.3
