Time & Location - High data usage

[gotiphone]

iPhone 5s running iOS 8.0.2

I am on a 2GB/month plan so I tend to keep a close eye on cellular data usage. Recently noticed that Settings > Cellular > System Services > Time & Location was almost 300MB in about 20 days. In the past, I have never seen this more than 3-5MB. Checked a friend who has the same hardware & software and his usage has remained under 10MB/month.

What accounts for this high usage? I have background refresh turned off, Location Services enabled only for GPS apps (e.g. Waze cellular usage is around 30MB) and Find My Phone.

What exactly does "Time and Location" mean, which system components use this service and why has the usage shot up 100 times from 3MB to almost 300MB?

Thanks

This exact thing happened to me after doing much research I found out that if you are playing a video game or watching a movie something that takes a lot of data usage and put the phone down at night and close it after the phone goes to sleep it automatically drops Wi-Fi to save battery usage. However it switches to cellular data and gobbles up Data usage. If you look at your bill you will see ever 3 hours you will be billed. I noticed at 12am 3am & 6am I would be charged up to a Gig while I was asleep. What I did to change this problem is turn off the cellular data button that stopped all charges and increased my battery life a lot. I think Apple has a software problem??
