Data usage spikes in the middle of the night as I'm sleeping even when though I'm on wifi.

So it's the fourth of the month and I find myself getting the "you've used 75% of your data text" and there is absolutely no way that I've used that much data. I'm on wifi 90% of the time. So I look at the usage logs on koodo/selfserve and find that there are a bunch of data spikes in the middle of the night around 2-5AM when I'm asleep. This makes no sense since just because I'm asleep, doesn't mean my wifi router is as well. Apparently the past couple days I'm getting 20MB spikes. Last night there were three in the span of a minute.
What's worse is that I didn't see this coming at all because the data transfer is not registering on the phone's own data monitoring system. Which leads me to believe that for some reason my data is being used up in some way not even connected to my phone.
This is a huge problem. What's going on?

I have a Nexus 5 running Android 5.0.1

Hey Matt, that is quite odd. Although sometimes when the wifi isn't as strong the phone will connect to data, have you tried using something such as 3g watchdog (it's an awesome app) also try turning off data at night.

This doesn't address the fact that my phone doesn't register that data is being used as it has always reliably done. It also doesn't address the size of the data being transferred. It's not likely that my router decides to get testy for a couple hours each night as it never has problems in the waking hours. I have no apps that realistically use 60 MB in a minute whether actively or in the background. And it would have to be background data when I'm sleeping at night. Something else is up.

My temporary solution is yeah, turning my data off at night. Hopefully that will cinch the problem, but that's a band-aid fix.

If you've recently come from KitKat to Lollipop, a factory reset might recalibrate the on-board data usage counter. This method has fixed a number of other anomalies associated with the Lollipop upgrade and Nexus devices. A factory reset will wipe the contents of your device, backup anything you want to keep.

Daniel's solution isn't a band-aid fix, it's actually the simplest, most effective way to manage your data, especially on a limited data plan.

It's a band-aid fix because it does not solve the problem at hand, it just covers it up.

I upgraded from Kit-Kat to Lollipop a few months ago. This problem only started in my latest billing period (starting Jan 28th). Before then nothing was amiss. My phone still tracks the data that I knowingly use during the day and all the data transfers that I knowingly perform during the day tracked and timestamped on the koodo selfserve site. I had heard of some people who's providers tallied up the data use in a day and lumped it to the bill at one point each day, but that's not the case for me.

I turned my data off last night and it seems to have worked to stop the mystery 5AM transfer, but it's a nuisance to have to be switching it on and off all the time when I'm coming and going from home work when it should be an automatic process. btw I have anything that automatically uses internet like dropbox or app updates set to only work on wifi so that's also not the problem.

I would like to know if anyone else is having this problem. I don't want to be paying overage charges for something else using my data.

I respectfully disagree. There's no problem to solve, it's simply a matter of personal preference on your part. If you don't want to incur data overage charges, turn off mobile data. If going through pages of settings to enable/disable data proves to be that much of a nuisance, install a data enabler widget on your homescreen.

Wireless routers are not infallible. The fact that mobile data was used while you were 'supposedly' on Wi-Fi should serve as a warning. I've been with Koodo for four years and use Wi-Fi extensively (with mobile data disabled). I can honestly say that in all those years I haven't lost a single kilobyte of data.

Respectfully, it's a band aid. When something was working well before and now it's not working the same, there should be a fix to return the product to the previous usage expectations. Not returning to the previous usability is a band aid.

Do a quick search for "samsung router" on this board and you will find that wifi and phone connectivity issues are not unknown.

Give rikkster's Farproc widget a go for a week. Easy as pie. Leave the house, turn data on, back home near router, turn data off, all from one simple button on home screen.

I don't think you've adequately read through what my problem is. The sheer amount of of data transfer that occurs at odd times just isn't natural to any of the apps I have on my phone. I've been getting multiple 5-20 MB spikes that occur within the space of a minute that can add up to 45MB. There are no processes on any of my apps let alone background processes that should even come close to that amount of usage. And in the past year since I've had this phone there hasn't been. For some reason the beginning of this billing period marked a change. This isn't just a matter of trusting my router not to fail. And while it's mostly occurring at night, there have been some spikes during the day as well. So I have to paranoid about having data on at any time because the random spikes could be incurred anytime. Which makes having data useless if I can't just leave it on to stay connected to things I need as I'm out of the house/work.
You can't honestly think at this point that it's a matter of the router having an occasional weak signal. And I will reiterate about my phone's data usage counter. It doesn't pick any of these spikes up. Right now my koodo bill says I have 480MB of usage while my phone says 200 MB. There has never been a discrepancy before. Something is affected the data on my plan and it's not my solely my phone.

I have been with koodo for 6 years now and never had a problem. I don't know why you bring up that as a quantifier for anything but there you go.

Factory reset has been suggested by many Mobile Masters.

You are not the only person disenchanted with Lollipop and wi-fi.

http://communaute.koodomobile.com/koo...

the gist of it is, for those who cannot read French, that his wifi is all $%#@&!.
Going on the internet with his Nexus 5 often leads to crashes.

You don't have to look past the 3rd google entry if you search for "Nexus 5 wifi" to find a similar problem: the phone thinks it's connected to wifi but can't download any data.

and there;'s more....

Protect your sanity and accept the humble band-aids suggested until google sorts this out.

In terms of turning off data at all times is a step I've already taken on my own before posting. I was just hoping for some feedback on this issue as I stated it instead of being given solutions to a perceived problem as if I don't know how my phone really works. I tried to be detailed. I've seen some threads about it happening on different phones and different providers but not really any solutions. Some people have issues with apps like google+ but I've determined that's not the case with me. Everyone else seems to have the same problem with people telling them it's auto-syncs happening when no, no it is not.

I am certain wifi isn't the problem. My connection never drops when I'm actively using wifi. And I have always had my phone set to keep wifi on when it's asleep.

My next course of action is indeed to factory reset my phone, but at this point I can't risk doing any trials to see if it works since one more data spike will put me over my monthly data usage. So I guess I'll wait the remaining 16 days to try it out.

I scanned for malware to see if that might have been it and I got nothing. I did change my phone number kind of recently (two months ago, same phone). I'm grasping at straws here but data from whoever has my old number is being counted towards mine? I guess that wouldn't explain why the transfers don't happen if I disconnect my phone so probably not.

Gonna try contacting google as well. Maybe try to get a higher tier of support from koodo from the last time I called.

I was going to suggest changing out the SIM earlier, since that's the gatekeeper for your data connection. Your having changed phone number makes me think again that the SIM might be an issue. New SIM will force a reset of your basic connection with Koodo.

Speak to Koodo, explain situation. Ask them if there is any data activity on your OLD number, maybe they will at least spring for a new SIM.
