Would love to hear from more people on this.
I have an iPad 9 running 17.7.2 and wonder if upgrading to iPad OS18 makes sense.
1) How well is iPad OS 18 running on the iPad 9?
2) Would upgrading to it that provide more time (years) for security updates?
3) I worry as OP does that if I don't upgrade soon, they’ll stop signing it and that, to get future security updates, I’ll have to jump to iOS 26! That doesn't sound inviting and could affect battery life.
4) Or, are security updates tied more to the device than to which OS it is running? What's the history been on this? Have users been forced to jump iPad OSs and IOSs if they want to get the latest security patches?
Oh, related questions on this.
5) Also have iPhone SE 3rd gen 2022 on iOS 17+. What's been the effect on iOS18 on those models? How well does it run?
6) And, of course, the same question as before. Should I upgrade to iOS 18 now for a longer time frame for security updates and to avoid the “monstrosity” 😁 that iOS 26 is?
Many have been burned by upgrading too far beyond their original OS and I’d like to avoid that.
I've been using two different iPad 9 with iPadOS 18 and on top of that tested 18 on most of the devices that can run it aside from the iPhone XR, 12, 12mini and some of the pro models.
This is my experience.
1. Ipad 9 can handle iPadOS 18 well, my mum are using an iPad9 with iOS 18 and it just works. She's not a heavy user but the basics, music, books, magazines, movies, webbrowsing and so on. The other one is what I use at the gym and that's mainly for using "Fitnessplayer" and "seconds pro intervall timer".
2. If will definetly provide you with a huge pile of security updates if you are on 17.7.2 today, there's been severe security flaws found after that. As of today the device will be update with the latest patches. BUT, at some point you need to update to iPadOS26 if you want to keep up to date. Looking back it seems like patches are stopped when the x.1 release are being released. We'll see what Apple does this year.
3. Haven't tested iPadOS 26 on the iPad9. Might give one of the devices an update when 26.1 is out if security updates for 18 is dropped.
4. Check out answer nr2.
5. Have been using iOS 18 and 26 on both SE2020 and SE2022 and it works fine. BUT, have only messed around quickly with 26 on these devices. I wouldn't update myself until 26.1 and do check reviews before updating to 26. my 5-10 minutes with these devices are far from how it might be using it as a daily driver. Have a handful using 26 at work with these devices and no complaints so far. Guessing they are fairly light users tho.
6. My 5 cent is update to 18 so that you get the latest seuurity patches and wait and see what Apples does, who knows, they might keep supporting 18 a bit longer this time. If you don't need specific 26 features and just want an updated device stick to 18 for the time being.
