Just days after reports of iPhone and iPad users running into storage issues while upgrading to iOS 8, Apple's latest mobile operating system, Microsoft has announced that it is doubling the amount of free storage it gives users of its cloud storage service OneDrive.

"We’ve been listening to the commentary about storage on the new iPhones released today and we wanted to get you more storage right away", the company said in a blog post, adding that it'll help you free up space on your device by backing up your photos, videos, and other stuff to the cloud.

iOS 8 is about one GB in size, but installing it over-the air requires around 5.7GB of free space on your device. The number varies depending on the device but it can shoot up to 7GB on certain iPad models.

OneDrive currently offers 15GB of free storage; to get the extra 15GB, just login or sign up for the cloud storage service if you are a new user, and enable the auto upload feature for the camera roll.

Although the software giant is aggressively courting iOS users, the free storage upgrade is also available to those who already use the OneDrive camera roll on Windows Phone, Android, and Windows.

The offer, which is available until the end of September, also means that the Redmond-based company is now offering more free storage than most of its US-based competitors, including Google Drive, Box, and Dropbox, which currently offer 15GB, 10GB, and 2GB of free storage, respectively.
