iphone 4s using mobile data at midnight even when it is connected to wifi

darraghjm

I have noticed over the last 3 months that my bill has jumped in price. It seems that at midnight every night my iphone is sending data on Vodafone live, even though at that time of night the phone is connected to the wifi in my house. it seems to be for a different amount every day and just shows up on the bill as "Vodafone Live!"
I rang vodafone Tech support and was told to turn off Cellular data and it would stop it happening, but obliviously I don't want to have to be turning it on and off everytime I want to use the internet.
any suggestions on how to stop this

More than likely jut the way billing works. O2 is the same. If your phone is locked its not connected to the wifi

Is that a iPhone specific thing? Sounds wrong. On Android phones I've had, even the phone is locked and its on wifi, it uses that not 3G.

No and On android you can change it but I think by default wifi is off or only on when plugged in when the screen is locked

Just sayin - On my Iphone and Androids Ive had - Once you are in a wifi zone that the phone knows the password- it will stay on the wifi - locked or not - plugged in or not.

It could be the signal is not very good in the room you leave the phone - and its dropping off wifi?

Vodafone accumulate Live usage for the entire day and then show the total data usage for that day as a charge shortly after midnight.

Also, with iPhones even if you have WiFi on and connected, unless you specifically disable 3G it will keep the 3G mobile data connection open for push alerts.

Ive looked for general background info before on how it works - but never heard that push uses 3g when wifi is available. Do you have a ref for that? Its hard finding out tech details on this.

It's not dropping wifi. When you lock an iPhone the wifi goes to sleep until you next unlock it

Can you not configure it to get the push on schedule, so it wakes up the wifi does its thing then go back to sleep?

I guess when I've ever done this I've had 3G off.

Certainly, straight from Apple themselves : [Linky]

Important: In iOS, Wi-Fi is used for push notifications only if there is no cellular connection or if the device is an iPod touch. For some devices to receive notifications via Wi-Fi, the device’s display must be on (that is, it cannot be sleeping) or it must be plugged in. The iPad, on the other hand, remains associated with the Wi-Fi access point while asleep, thus permitting the delivery of push notifications. The Wi-Fi radio wakes the host processor for any incoming traffic.

Funny how features like this always cost the end user money rather than cost the network.

I have to assume that's intentional.

Users should really have a data plan on iPhones, or any smart phone for that matter.

You can still be "smart" about how you use it.
