Public Radio Exchange Labs has recently discovered a bug in iOS version 6.0.0 which has reportedly been causing podcasts to download multiple times, and could potentially lead to data overage charges.
One of PRX’s popular podcasts, This American Life, had noted unusually high bills based on bandwidth overages, and suspected that Apple’s new Podcasts app was the cause of the “rather extreme” increase. After extensive testing of both iOS 5 and iOS 6, it was determined that iOS 6 contained a fatal flaw which caused files to download multiple times, taking up to (and over) three times their actual size in bandwidth.
“The player appears to get into a state where it makes multiple requests per second and closes them rapidly, … Because the ranges of these requests seem to overlap and the requests themselves each carry some overhead, this causes a single download of an MP3 to use significantly more bandwidth than in iOS 5. In one case, the playback of a single 30MB episode caused the transfer of over 100MB of data.”
It should be noted, as well, that this bug effects third-party podcast apps as well, not just the Apple Podcasts app.
This issue is easily fixed by upgrading to iOS 6.0.1, and you really have no reason not to (unless this app has temporarily eaten up your bandwidth for the month). Have any of you experienced this issue under iOS 6.0.0? Let us know in the comments.
