Why is my phone using data in the middle of the night

Looking at my data usage online, it is saying that every night at really strange times (like 3am) my iPhone 5s is using data. How can this be if I'm clearly sleeping and not using my phone and my phone is constantly on WIFI at that time of night anyways? Some are very small but others range to 10mb which is crazy! I reset my stats in my settings to see if any apps were to blame and they aren't, so it must be something running in the settings or something I'd guess. Any ideas?

Typing "iphone data use" in the search box brings up a number of discussions.

I am no iphone expert, but mobile masters have said that wifi is on ONLY when the screen is awake. Best to turn off data entirely when you put yourself and the phone to sleep.

Okay thank you. That is really unfortunate. I wish that they had a setting for that.

You can set all your email accounts to 'fetch' so it only loads emails when you open the mail app. You could also put your phone in airplane mode overnight, if you need it as an alarm clock.

Also check your bill. It might be reporting the time as GMT rather than local time, thus 3AM GMT could be as early as 7PM PST, and therefore within the window of your use.

While what you said was true with older iOS versions, I do not think on newer version this still applies. I remember that when my phone was locked for a certain amount of time before ios 7 I think, it would disconnect from wifi. This is not the case anymore. Every time I open my phone, it's still connected on wifi even if it's been a while since it was locked. As you can see, I'm now having this problem

But it may be true if Dani is on a earlier version of iOs

Here's what my usage looks like!

This is weird. Try resetting your data usage stats one night (Settings > Cellular > Reset settings on the bottom) just before going to bed and post the application that is using said cellular data! I'll do the same to see if I use or not data during the night!

Okay I will do that tonight. But like I said I did that a few nights ago and no applications used data. It was just the "system services". It seems to be drawing data throughout the day too when I'm at home on wifi. I'm suspecting its like the others are saying and my phone is dropping off the wifi when it's asleep which is stupid annoying. Keep you posted tomorrow.

This feature doesn't exist anymore on new OS's I think + you can see what uses data on system services just click on it! Also, I think that data used there isn't enough to be worried for going over your max amount!

Ya but sometimes it can be up to 10 mb. Which is a lot considering I only have 400 mb per month. It's just kind of everything drawing in the system services.

So that first pic is the past few days when I never left my home wifi. The second is what was used last night after I reset the usage.

Unfortunately I forgot to check mine and I've left my home wifi.

How to close your PUSH notifications : Settings > Mail > Fetch New Data > then disable push.

Doing this will disbale the automatic notificaiton when a new message is in your inbox. You would need to open the mail app every time.

Here's mine! You seem to be right, I've used some too during the night! What I suggest is putting your phone in airplane mode during the night

You could go on apple forums to ask some help there. They may know a lot more then we do on how to limit those kind of usage!

Oh no, here's something. It might help

From here : http://www.iphoneincanada.ca/how-to/i...

The problem exists in iOS 8 and iOS 8.0.2. Users, after checking their data usage, are seeing higher than normal usage (including ourselves). Part of the problem may be possibly related to new options in iOS 8 which use cellular data as part of iCloud. Here are some possible fixes to try and reduce your data usage.

Under Settings > iCloud > Documents & Data, toggle off ‘Use Cellular Data’ and any other apps you don’t want to use data.

Tell us how it went after that!
