Isn't it just great that we now live in a world where data can travel everywhere with you, seamlessly? Open up an instant messenger on your phone and voila, all your conversations are just where you left them last, perhaps on your PC or tablet. The same goes for your email, photos and most every data that you decide to hand over management of to Google, Apple, Microsoft or any other cloud service. However, as most of you have surely considered at one point or another, while this might happen "automagically", it does require quite a bit of background data usage, which most likely comes out of your data plan. Opera has always been a bit more concerned than most for proper mobile data utilization and its latest set of statistics provide a good reason why.

Smart Alerts is a feature within Opera Max that informs you if an app is eating away too much data in the background and allows you to stop the leakage, if deemed unnecessary. You can get Opera Max free on the Google Play...
