I am using an iPad 3 (WiFi) on iOS 9.2.1 and since two days I have been having an issue. I don't have an unlimited WiFi connection, I use my mobile phone hotspot for iPad. Now whenever I connect my iPad to hotspot, it starts using very high data, i.e, 2-3 MB every second without any app running. I also tried turning of Background App Refresh, Automatic Downloads are turned off, I tried a soft reset but to no avail. Any idea what's causing this??
P.S: By data, I don't mean mobile data on iPad(My iPad is WiFi only), I mean that it's using the data from my hotspot connection.

I doubt highly that it is the iPad causing interference. What I could expect is that the base station at your friends place can't keep up with all the wireless devices at once. If the TV is using 802.11g as are the other devices that disappear and then your iPad using 802.11n then the base station might crap out. Have seen a few similar cases before.
Additionally some base stations have limitations, example older AirPort Expresses could manage 5 or 10 clients. Once an 11th device comes into the network then a device or two or more might be kicked out because of the DHCP TTL time out. Going static with your IP address won't fix this, only a better base station, eg. the newer Express or Extreme.
You could use Shell script in a Applescript Application that checks the available wifi list. And pops up a notification when the one you want is in the list.
The code is commented to explain how it works.
on idle -- A on idle handler will run the code within it and then set the app to idle. Using little cpu. It will then repeat this every #n of seconds ( determined by its return number)
set theWifi to "weehronetwork" -- the wifi SSID
set theList to paragraphs of (do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s| awk '{print $1}'") -- get the wifi list
if theList contains theWifi then
display notification with title "The WIFI" subtitle (theWifi & " IS BACK UP") sound name "Sosumi" -- display a notification.
end if
return 60 -- run again in #n seconds
end idle
Save the Applescript as an Application and check Stay open.
When you first run the App. and it displays a Notification, it will then be shown in the System preferences --> Notifications. From here you can determine the Notification type.
Note. I have used a sound in this code. But if you uncheck 'Play Sound for notifications' the sound will not play.

Much of iCloud will synchronize when you are connected to WiFi and not cellular data.
Check in the settings app and be sure to turn off iCloud backups (or restrict severely the parts of the data that backup). Also, look at things like iCloud photo library, podcast apps, My Photo Stream and others that wait until you connect to WiFi to avoid burning cellular data.
Can you take it to a proper WiFi temporarily to see if after 30 minutes whatever backup and sync are needed complete and then you will have lower usage going forward?
