Iphone battery runs flat fast because of mobile data is switched on, although I am on wifi

Hi, my Iphone battery runs flat fast because of mobile data is switched on, although I am on wifi. This happens only since a few week. If I switch of mobile data, everything is back to normal. If I am out of data, it is also fine. My battery health is at 86%. Any ideas, why this is happening?

iPhone, iPhone OS 3.0.1

Hi Brian,

Many thanks for your hints. I had only apps on mobile data, that I need. Battery of 86% should be fine. Anyway, my problem is solved. The effect of the draining battery is not there anymore. I have no idea, what caused that, but everything is back to normal since two days. Maybe it has to do with my provider (Telkom). Thanks to everyone for their help.
