M1, iPhone 6+. 4GB Cellular Data quota, I accidently checked M1's data usage yesterday and just realized it already used 3.96GB... in just 2 weeks, before switching to iPhone 6+, the old iPhone 4s never exceeded 1GB/month for the same daily usage.
I am not complaining OS or Phone issue, because it did use that much after checked Settings/Cellular, 80% are used by YouTube app :-( I think video streaming size on big screen + 4G is much larger than small screen + 3G.
So, you may want to check "HD Video on Wi-Fi Only" in YouTube app settings to avoid overaged data charge.
