Cannot pinpoint a specific iPad, but for stability:
- higher iPads have more RAM and depending on model faster USB/Wi-Fi/Bluetooth. The step up to the Air is significant in this regard. The iPad Air 4 is bang for buck with the Air 5 a bit better. Pro iPads have more of all that.
BUT I have a feeling your iPad 9th gen is MORE than good enough as many of us run just fine on older less powerful hardware. Try some of this to see if it makes the system more stable:
-
disable all Widgets, Notifications, SIRI, uneeded Wi-Fi / Bluetooth. Any app with a scheduler that periodically polls the CPU or checks the WIFi/Bluetooth connections.
-
set Focus to Do Not Disturb
-
also go through a few “battery saving” YouTube videos and turn off other unneeded features. This can be odd stuff like screen parallax background movement etc. Not only will the battery last significantly longer, but I find the system feels “more rock solid”.
FWIW - I’ve never had the iOS version crash on me, but I had some crashes in macOS that got solved by doing similar optimizations.
