New iPhone launch rumors have been springing up from a variety of sources for the last few months, and we've now got a clear picture of some specs of the iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max and iPhone 13 mini.

Global tech giant Apple is expected to unveil the upcoming iPhone 13 series on September 14, media reports say.

The upcoming series will go on pre-orders from September 17 and it is said to go on sale starting September 24 in the market, GizmoChina reported on Friday.

According to IT Home, the iPhone 13 series is already listed on an e-commerce website in China.

Apple is likely to unveil all four models of its upcoming 'iPhone 13' lineup with larger batteries, an updated chipset and expanded mmWave 5G support, a report said earlier.

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 devices is said to be powered by Apple's next-generation A15 chip manufactured based on TSMC's 5nm+ process, with a USB mini c charging port as on its latest iPads.

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.

From everything we've heard so far, the iPhone 13 is set to offer a 120Hz LTPO display on both Pro models, improved battery life thanks to a more efficient 5G modem, and substantial upgrades to the all-important cameras. That includes a new portrait video mode.

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.
