Nokia unveils Lumia 920 with 4.5" display, PureView camera

The new Lumia 920 features a design similar to the previous Lumia 900 launched last year. But inside it has been upgraded with a 2,000mAh battery, near-field communications chip, integrated wireless charging, and an 8-megapixel camera that can shoot 1080p high-definition video.

The Finnish handset maker claims the Lumia 920 captures the highest quality video and images on a smartphone. Nokia's "PureView" technology is reportedly able to take in five times more light than competing smartphones without using flash.

Nokia has also boasted that its new Lumia 920 features what has been branded as "Super Sensitive Touch." The new curved glass touchscreen will allow use of the device while wearing gloves.

Also announced on Wednesday is the Lumia 820, a smaller 4.3-inch, lower-end device that has the same unibody look and feel as the larger Lumia 920. The handset has exchangeable shells that allow users to change colors or add wireless charging, and also allows users to input microSD cards.

Nokia did not announce pricing or availability of its new Lumia series on Wednesday. However, the company said that its phones will be available in select markets in time for the holiday shopping season. Both phones will be available in 4G LTE and HSPA+ variants.

The unveiling of Nokia's new flagship handsets comes just a week before Apple is set to hold a media event where it is widely expected the company will introduce its next-generation iPhone with a larger 4-inch display. This week, Apple sent out invitations to the press declaring "It's almost here," with the Sept. 12 date casting a shadow in the shape of the number 5, hinting at the so-called "iPhone 5."
