San Francisco, Sep 14 (IANS): Apple is all set to host its special "California Streaming" launch event on Tuesday and this year one can expect the tech giant to unveil the iPhone 13 lineup and the Apple Watch Series 7, along with new iPads and Macs.

The iPhone 13 lineup may mirror the iPhone 12 family of phones, with a 5.4-inch iPhone 13 Mini, 6.1-inch iPhone 13, 6.1-inch iPhone 13 Pro, and 6.7-inch iPhone 13 Pro Max.

The upcoming iPhones are widely believed to bring some upgrade.

The iPhone 13 lineup will start with 128GB of storage, with no 64GB option for any models.

The iPhone 13 Pro and iPhone 13 Pro Max will be available with up to 1TB of storage, which would be the largest capacity ever offered for an iPhone, reports MacRumors

The devices are said to be powered by Apple's next-generation A15 chip manufactured based on TSMC's 5nm+ process.

The entire iPhone 13 range is also expected to sport the LiDAR sensor. The sensor first appeared in the latest generation iPad Pro in March this year followed by the iPhone 12 Pro and iPhone 12 Pro Max.

A recent report said that has claimed that the Cupertino-based tech giant will increase the price of the upcoming iPhones to compensate for rising chip production costs.

Apple may also launch Watch Series 7 with a smaller "S7" chip, potentially providing more space for a larger battery or other components.

This new chipset will be built from Taiwanese supplier ASE Technology. On its website, ASE Technology confirmed that its double-sided technology will allow for module miniaturisation.

The Apple Watch Series 7 will come in various screen sizes from 41mm to 45mm. The 45mm version is said to pack a 1.9-inch screen with a resolution of 396 x 484 pixels.

The company is expected to release the new generation of its smartwatch and budget TWS earbuds.
