I've been looking through my data allowance and data usage and I've noticed my mobile is accessing the internet when I'm asleep and connected to my home wifi.
It is also connecting to the internet when it's safely secured in my locker when I'm at work.
Should I just power it down when not using it, or turn off data roaming.

Many phones switch off wifi when you leave them for a while in order to preserve battery (it can be disabled)
You would have to switch off mobile data and not data roaming which is for when you are abroad
