I recharged 1gb 3g data plan on my idea prepaid mobile no. And only used this data for surfing the Internet with UC Browser & all my 3g data used within 10 days. I don’t know where my data had gone. After some days I noticed that when I open mobile data on my Android smartphone, many apps show the notifications that appear in notification bar. I checked and found that many unwanted Apps are running in the background. So these apps use data in the background.
It is huge problem in the Android smartphone because when we open mobile data, Apps (software update, Google Play Store, Google Play services, Whatsapp, Antiviruses, Google+, Hike, Facebook & others) that running in background use the data every time & update itself without your knowledge. you can’t control it, but if you want to save your data, You can disable background data usage by Restrict background data option.
