Prevent & disable iPhone iOS 9.2 from auto downloading updates?

iPhone 5 iOS 9.2 -

Today morning found it had auto downloaded 9.2.1 update - Around 200-400 MB.

I have a data cap with ISP so I dont want this happening on Apple's control.

How can I prevent & disable this?

I found these older articles but does not seem to have worked/ stopped the download.

  • Thanks for posting the links to the discussions ... Yeah seems it's really hard to find a solid answer on this, I don't think the Wi-fi assist feature is relevant here and I don't think there's an "app" listed under Cellular Data, if you turned off all cellular data it would stop this but that's no fun! – JimLohse Jan 29 '16 at 14:00

The closest I came was preventing all my iOS devices from reaching the update server. This envolves configuring your internet router in order to do so.

Configure your router to block the following domain: mesu.apple.com

Doing so will still allow your iDevice to talk to the Apple Store, allowing you to download/update iOS Apps.

Some routers (like mine) only allow me to block 'web sites' not domains. Luckily, that is all we need to do. Blocking https://mesu.apple.com also does the trick.

I would say blocking the whole domain is a cleaner solution if possible however.

Really, if your iPhone is on Wi-Fi and an update is available, it will download the update when you're probably asleep (2:00-4:00AM). There is no way to disable this.

A workaround would be to turn Wi-Fi on your iPhone off when you go to bed.

  • So this is a new thing that iOS 9.2 does automatically? So, on 3G, WiFi disabled, it wont do so? – Alex S Jan 29 '16 at 9:52
  • @AlexS It's not new for iOS 9.2, but I'm not sure when this started. If you turn your Wi-Fi off it likely shouldn't download the update over LTE or 3G. – RedEagle2000 Jan 29 '16 at 13:24
  • Just make sure that Use Cellular Data is not turned on in the iTunes and App Store menu of your device's Settings. – Munesawagi Jan 31 '16 at 16:55
  • @angelplayer Actually, I think that that's different. One can't even download an update over cellular if he wanted to, so iOS doesn't do it by itself. – RedEagle2000 Jan 31 '16 at 19:07
