Nokia will unveil its next Windows Phone 8 flagship handset and a mid-range model at a joint press event with Microsoft on September 5, according to inside sources speaking to The Verge.

The Finnish phone maker’s new range-topping Lumia 920 will reportedly offer an impressive feature lineup, including wireless charging, a dual core 1.5GHz processor with 1GB RAM, 32GB onboard storage, and a 4.5-inch HD display all wrapped in the same Unibody style design as its predecessor. The phone will come in multiple colors similar to the current Lumia range, as depicted in leaked photos last week.

Speaking of the wireless charging specifically, the sources say it will use the Qi wireless power standard and will therefore be compatible with other wireless charging products. The feature makes charging as simple as placing the handset on top of the charging surface (pictured below).

Previous rumors suggested the Lumia 920 might include the 42-megapixel camera found on the 808 PureView handset, but apparently that won't be the case. While it will receive the “PureView” branding, it will apparently use an 8-megapixel version, with improved stabilization and software. Above the display on the front will be a 1.3-megapixel front facing camera for video calling.

Nokia is expected to share more details about the 4.3-inch touchscreen mid-range Lumia 820 during the special event on Wednesday, as well as revealing the full specifications of both devices. It’s unclear if we’ll just see the Lumia 820 and 920, or whether we’ll see more models announced come September 5.
