IOS 12- Iphone 5s and newer

IOS 13- Iphone 6 and newer

IOS 14&15: Iphone 6s and newer

IOS 16: Iphone 7 and newer

IOS 17: Iphone 7s/8 and newer

How do you figure? iOS 11 just dropped two iPhones. 5s is now a pretty old device. No way it gets iOS 13. No device has ever gotten 7 versions of iOS.
In theory the iPhone 6s/SE could be the first to get 7. It's not that far fetched, the A5 chip got six. And power wise, that chip was heavily outdated only two years later.

The A5 didn't actually get 6 though. This has been discussed in the past around here. The A5 didn't exist until 9 of 16 months into iOS 4. So it really only got half of 4, then 5, 6, 7, 8 and a really watered down version of 9. I don't really classify that as 6 full years.

But yes, the 6s could be the first, but not iPhone 5s. It does not have the hardware.

Yep, I was mainly comparing processing power not lifespan. The A5 was able to get iOS 9 even though it only had a small fraction of the A9's power. Meanwhile, the A7 has just under half of the A10's. Seems unlikely but it's not as far fetched as it sounds.

no, ios12 will support iphone 5s
(in my opinion ios 13 too)
I agree ,iOS 12 will probably support iPhone 5s, however,iOS 13 won’t support it .

No way! 5s won’t get iOS 13.
[doublepost=1499060961][/doublepost]I think that Apple will support iPhone 5s next year. But , it will be very slow ! It’s already slow on iOS 11. So , no way IOS 12 will make the device faster ,it will slow it more.

The beta is no slower than iOS 10 and maybe slightly faster in places. I have two iPhone 5s that I'm using to gauge.

This video begs to differ:


However, it's an early beta and contains debug code and such. You can't really gauge it at this point. The final release should be a bit faster.

Right, so it's one experience against another, with things changing as the beta starts rolling. In the video, some of the clicks, did seem to be faster on IOS 11. I don't know about you, I don't care if an app opens .01 second slower, as long as overall the phone is faster. The biggest use case being safari.

Some of the recent drops have been to do with severely limited RAM for the new OS (iOS 10) and 64-bit (iOS 11). I think we can expect the new few iOS releases to support the 5s onwards, but the features might start to get limited on the older devices by iOS 13 onwards.

Next cut I think will be all 1GB RAM devices, so all A7/A8 powered devices except the A8 devices with 2GB RAM.

A9 chip is pretty overpowered, and with extra RAM to boot, so it's got plenty of room for OS advancement.

The limitations have always been artificial and based on Apple's four year support for their Ax chips.

RAM has never been the limiting factor and won't be in the future.

The latest version of macOS requires 2GB RAM. That's a desktop operating system for x86 with support for external drives and a proper file system. Do people really think 1GB isn't enough for iOS?

iOS 11 - A7 and newer
iOS 12 - A8 and newer
iOS 13 - A9 and newer
iOS 14 - A10 and newer

Apple relies on customers replacing their iOS devices on a regular basis. iPad sales performance shows what happens when customers don't replace regularly. Apple isn't about to give 2GB RAM devices extended iOS support for no good reason.

Nah, Not Really. iPhone 6S in iOS 11 is Trying hard or iPhone 7 Wannabe in terms of speed but failing. If you compare iOS 9 vs 11 It's much slower, to make matters worse even after a battery replacement it iOS 11 drains battery on OLD CPU such as A8/A9 below. It's even 100 Times worse a big big battery drain on A7 Devices
