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
