A new class-action lawsuit has been filed against tech giant Apple in California. The lawsuit has been filed by two Miami residents - Paul Orshan and Christopher Endara - who have accused Apple of 'false advertising' about the storage space on its iPhone and iPad.

The two plaintiffs have claimed in the lawsuit that Apple 'misrepresents' the amount of storage capacity available on its popular handsets; and are seeking $5 million in damages from the company.

According to the plaintiffs, the 16GB iPhones and iPads which they have purchased do not actually have 16GB of storage space as advertised by Apple. Moreover, the plaintiffs have also added that the upgrade of the devices to Apple's latest mobile operating system - iOS 8 - further reduces the storage space on the devices.

Drawing attention to the specific figures pertaining to the space consumed by iOS 8 on an Apple device, the plaintiffs have asserted that iOS 8 takes up 18.1 percent of the storage space available on the iPhone 5S; and 20.6 percent space on the iPhone 6 Plus, thereby underscoring a storage-space loss of up to 3.3GB for the users.

About Apple's allegedly false advertising about storage space on its devices, the plaintiffs said in the lawsuit: "Apple's misrepresentations and omissions are deceptive and misleading because they omit material facts that an average consumer would consider in deciding whether to purchase its products."
