What does reset statistics mean? On iphone 5s?

I have like 50.1 gb on my phone. I saw reset statistics on the botton(cellular>go to the botto) what does it mean? And does it lower my data and lower my bill?

Resetting the statistics clears the data counter on the phone. This is good for those that want to know how much data the phone the has used since the last reset. It will not alter any settings or lower data, bill, etc. In the cellular settings you can see how much data each app has used and also restrict certain apps from using your data plan. Try out Onavo to track and manage your cell data usage.
