One of the new features of iOS 7 is its multitasking that allows developers update your background apps. If we leave an application open and do not close it, the developer has the option that the information that appears in his application is updated automatically, but be careful, because updating in the background can be expensive, as reported this week by the person in charge from the «Check The Weather» application. The fact that the application has to be calling your servers every so often will significantly increase traffic and, therefore, would be very expensive.
We will use the "Check the weather" application as an example. When Apple released iOS 7, the creator of this weather display app inserted the option to refresh the weather every minute. This raised, considerably, the demand to your servers and the final price who had to pay for all those requests from user applications. In the graph that heads this news you can see the peak that it reached when the developer enabled this option.
Realizing that the background update every minute would generate a few costs too high, the developer of "Check The Weather" decided to limit the background update of the application to a longer time interval.
Therefore, if you are a developer and you are thinking of using this tool, keep in mind that this can happen. You can find some tips on how to save data consumption on your servers from the creator's official website from "Check The Weather."
