It's a choice you get.

You can decide for yourself which connection you want to use.

That's because your carrier supports 5G or 4G.

It really doesn't matter.

I have that too here (I have 4 G).

If you choose Don't use Mobile Data, the Wi-Fi connection will be used.

Verify that Low Data mode is not turned on for your Wifi by going to Settings > Wifi > [tap your current WiFi] > Low Data Mode.

There is the same setting that can be done when on Battery at Settings > Battery > Low Power Mode.

I have been noticing this too when I just did an update on one of my games. Even when I am on Wi-Fi it is asking me. My wife’s phone is the same. I never noticed it before. I will have to test it on another wife at a later date.

Base on your screenshot, please check the Wi-Fi connection.

You need to have a good Wi-Fi.

👉 If they are On, turn Off Hotspot & VPN.

Charge the battery > 70%.

If you have an 'unlimited' data plan, click Download, then the update will use the data.

You can also check the Wi-Fi connection first, then click Later on Wi-Fi.

Then nothing happens. The app(s) that have updates just change to darkened and say "Waiting" underneath.

Looks like it's looking for a connection.

Later on Wi-Fi doesn't mean Right away.

Try to do a force restart -> Force restart iPhone – Apple Support (UK)

Did they ever fix your problem? I just got a new Xfinity router (the boxy white one) and all those problems started happening. I replaced my iPhone in the same week, so I thought it was the new phone but it may have been the router.

No it still happens. Maybe it was the recent update? I don’t know I haven’t tried another Wi-Fi yet personally. Though I do have the white box Xfinity too. I can confirm it hasn’t been using cell data.

Good to know. Seems like something Xfinity needs to figure out with Apple. I’m seeing these threads pop up more often as more people get the new router so hopefully Xfinity is addressing it. Doesn’t seem to affect my network speeds, and now knowing your iPad situation I’m not very concerned that it’s actually using cellular instead of Wi-Fi.

I have just got a new phone because my other one messed up. I logged into my apple id etc. everything updated and some things were downloading. i’m doing this through mobile data and i’ve changed the settings in my settings but nothing has changed they just are stuck half way and won’t download anymore than they have.

I turned this off and it got rid of the problem. 🤟🏽
