I have an iPhone 6s that is perhaps 2 years old. For the past 6 weeks, it has been using a lot of data if I use the Internet using cellular data (rather than WiFi); for example, browsing a few sites last night used 221 MBs of data in about 4 minutes. The battery also very quickly runs low.
Is there a way to fix this?
This happened in the past a few times when I had used a lot of data (not realizing that I needed to shut off cellular data and use WiFi only), but the issues always stopped within a few weeks, perhaps once that billing cycle was done.
This time, however, I used a lot of data in March and the issues are still going on, more than a month later.
Thanks.
