    I'm wondering if it's finally safe to update. My wife's and my iPads (2017 9.7") and iPhones (6S) are still on 10.3. We'll be going on a trip, soon, so I'd like to know if it's safe to update or is 11.x still problematical?

    Note: We don't have iTunes, nor would it be practical to attempt to install it. MS-Windows is a rarely-used "secondary" OS for us, and we have no Macs. So backing up to iTunes is a non-starter. If iOS 11.x is likely to trash our devices, we'll just stick with 10.3. In that case: Is there any way to stop the repetitive iOS 11 downloads and notifications?

    Thanks!

    To stop the downloading just turn off your wifi when you plug your phone in to charge overnight - that's when the downloading occurs.

    If you have any apps that haven't been updated to a 64 bit version they won't run in iOS 11 so beware.

    The only problem I know about in iOS 11.3, occurs when your screen has been replaced by someone else but Apple or an authorized partner, and this only happens to the iPhone 8, 8 Plus and X. There haven‘t been any complaints since it has been made available, two weeks ago.

    With every update, Apple provides security fixes as well. In iOS 11, there have been a few quite important updates. One of those was an update just to improve the security (11.2.2), and it was recommended for all users. It mitigates the effects of Spectre. Since 11.2.2 is not signed any more, you‘ll have to update to 11.3, in this case.

    Until you update, you'll always get those update notifications and there's no way to stop them. Apple REALLY wants every possible device running the latest the latest operating system.

    We should probably update, instead.

    I went to Settings -> General -> About and tapped Applications. Nothing came up, so I guess I'm GTG.

    Thanks.

    I'll give it a go on my tablet, first, I guess, and go from there.

    Upgraded my iPad yesterday. Other than insisting it couldn't log me into iCloud, when it turned out it had, it went smoothly. Encouraged by that I did my iPhone this morning.

    The phone went not quite as smoothly. First it pulled the same "can't log you into iCloud" stunt, then twirled endlessly on fetching the new end-user agreement for it. Having read the best cure for those problems is log out of iCloud, reboot the phone, log back in: That's what I did.

    During that process it claimed to have sent me a verification code it had not, in fact sent. I told it I hadn't received it and send me another via text message, at which point it simply logged me in! One or another of the codes later showed up on my iPad. Never did show up on the phone. Seems like their process is a bit b0rk3d in this respect.

    Watch upgrade was slow, but uneventful.

    Later, when I tried to make a call, I found I had no service. Rebooted the phone again and had three bars. Hmmm...

    The upgrade process hammered the phone's battery. By the time all that was done it was down from 100% to 54%, so it's back on the charger. The new battery health thing claims I'm GTG with 85% battery life. The upgrade didn't much affect the iPad's battery.

    Just thought I'd update.

    The only problem my wife and I have noticed with iOS 11.3 on our iPhone 6S' is that maybe battery life is worse? It's hard to say, because we used our phones much differently just after the upgrade, having been on a trip in Europe.

    Now that we're back home we'll get a better idea. Also upgraded my phone to 11.3.1 last night. My wife is upgrading hers as I type this. So far nothing of consequence to report on that front.

    ETA: Except that, as with the update to 11.3: My phone lost cellular service. A reboot did not restore it this time. Went into airplane mode and back out. I now have service again. Weird.

    Regarding authentication with text if you have multiple devices connected Apple will verify automatically without you receiving a text code. As you are logged in which explains why it logged you in. It streamlines the process. If you have one device this will not happen.

    I love being able to setup a new device automatically using one of my updated devices and the camera, sweet and easy

    Your devices just updated through several versions of IOS. They need to re-populate. That could take a couple of days. And they all probably need to be rebooted too so shut them off for a couple of minutes each. In a few days battery life should be fine. Also, every time there there is an update, I check my Settings as Apple defaults some things, like Bluetooth, as on and I keep it off.
