That's already better than before. Been using iOS devices since the first iPhone and my experience with older iOS devices is first year good performance (definitely not lightning, though, I still recall checker boxes while waiting for Safari to render webpages), 2nd year acceptable performance, 3rd year replace. Honestly, it wasn't until A6/A6X that I could stretch usage to year 3 or beyond.People always say the same crap after a new iPad is released. "The iPad 4 has the new A6X and they bumped up the RAM from 512MB to 1GB. It will easily last you for 5 years until 2017". Meanwhile those same people probably already upgraded their iPads multiple times in between 2012 and today.
Forget all specs, general rule of thumb is first 2 years will have lightning performance, the 3rd year will have good performance, the 4th year will be usable but you'll want to upgrade, and by the 5th year you will be begging to upgrade.
Will it last as long as the iPad Air 2 did ?
iOS 12 is going to be an anomaly in that regard. It is primarily to clean up the remnants of mess from iOS 11. They're running out of time on their development cycle so they have to release the remaining fixes/clean-up in a major release.If Apple continues to emphasize fast performance like they have with iOS 12 I could see the current pros getting updates until 2025. Hell the air 2 will probably be updated for another 3 years.
I disagree - I believe the technology they use to ramp up the CPU will be continued in future OS updates and this focus on performance will have long lasting improvements because the fundamental principles here are applicable going forward and don’t see any reason they’d not continue that tech in iOS 13 and beyond. Otherwise iOS 13 will be a huge downgrade from 12 and I don’t see them doing that at all.iOS 12 is going to be an anomaly in that regard. It is primarily to clean up the remnants of mess from iOS 11.

This is one of the reasons why I'm of the opinion that there won't be any new iPads for the rest of 2018 (with the possibility of a mild processor bump).
The iPad Air 2 is already exhibiting this phenomenonRealistically iOS devices A9 and 2GB of RAM and better can probably be expected to last their entire iOS update life cycle without slowing down in the way previous devices have (for example the A5 based devices are possibly the most notorious for getting long support but really feeling underpowered past iOS 7). You might see them get ‘less snappy’ but they won’t likely slow to a crawl or be unusable with the keyboard lagging your input and making typing near impossible, for example.
Don't worry. Regardless of whether or not new features and functions are added to iOS, you can guarantee that they will release new devices every 12-18 months... and each release will include "must-have" new features.I am not sure slowdown because of new feature rich OS version will be sustainable in the future. iOS devices have had a very nice exponential development in CPU and GPU compute power. That has slowed down significantly the last years with more moderate gains year over year.
As an example, for daily use I cannot perceive any difference between IPP1 (2.5 years old work) and IPP2 (1 year old, home) unless I run high ends Apps like Civ 6. Annotate large pdf files (>200 mb, 600 pages) work great on both devices.
Furthermore, each node shrink takes longer and longer time so obvious gains in compute power will take longer time to achieve. Sure architecture can improve but the gains are smaller. Only way to increase compute power significantly without node shrink is to add more cores (Coffee lake, A11) but that does not automatically translate to better performance in all software like a node shrink.
Hence I predict the that longevity will increase for iOS devices for "normal" users. Good for the wallet and the environment but bad for the ugly "monster" inside me waking up now and again demanding a new device to play around with.
