One question for iOS 7.1 beta users.

This is probably because the only thing that needs data when the screen is off on an iPhone is notifications.* It would therefore seem unnecessary to maintain both a cellular and a Wifi connection.

* Unless it's downloading something in the background. Not sure what happens then, but I presume WiFi stays on.

Turning off cellular data != airplane mode. I'm surprised just how little you guys know about the phones you use. It's one thing to not know and therefore question and another entirely to call me a troll and poke fun at me for discussing something you know clearly very little about.

Turning cellular data on means your turning off data. You don't need cellular data to text/call. Turning airplane mode means that you can't do anything with your phone: no call/text/internet.

Yep.

Usure if serious or troll...

You realize you would not receive sms, calls, or push... There defining functions of a mobile phone.

I LOL'd at this ... typical apple user.

Because one user getting something wrong or over-exaggerating is somehow typical of most or a lot of them.

No, but that pompous, smug, know-it-all attitude is indicative of quite a few.

So you are both asserting that with the cellular transceivers and amplifiers turned off, you can still make phone calls and receive sms? Astonishing.

Correct with airplane turned off...

Do you even know what cellular data is?

Please educate yourself

Mate, the original post you scoffed at said this: "Would be better if the phone stayed on WiFi and just turned off cellular data."

You scoffed and said you wouldn't receive calls or SMS if it did this.

He was quite clearly referring to something which would behave the same as the setting in iOS 7 under Settings > Mobile > Mobile Data. That's the British English label; I believe it's even labelled Cellular Data in US English.

If you turn this off, you still receive phone calls and SMS. It just disables internet traffic. This is the behaviour he said "would be better."

Since that original scuffle, there's been a quite interesting discussion about the hardware and software processes involved with the radios, but on this basic point - about whether turning cellular data off would stop calls and SMS coming in - you were wrong. You should probably drop it.

The astonishing part would probably be commenting on something without reading the thread. Unless this is yet another mistake, making it quite a few in this thread.

My phone was recently next to an old clock radio that picked up interference from the LTE radio. You could hear (very loudly!) when the phone transmits. Across the hotel room, even.

Once a data transaction is complete and the LTE radio is idle, it stops transmitting. Completely. For many minutes at a time, even. You can the occasional burst of data transfer, but it's such a small amount of time that the impact on the battery is likely minimal.

So stop worrying about the cellular radio using power when it's idle. The engineers that developed the standards thought about this stuff already.

Some on iOS 7.1 beta 2 my iPad Air looses internet but none of my other devices (iPod touch 5 and iPhone 5 on iOS 7.1 beta 2) looses internet. Sometimes putting airplane mode on then off fixes it but she it doesn't I do a hard reset.
