There is definitely nothing new in terms of processing power and screen technology. The Lumia 925 has the same 4.5-inch 768 x 1280 pixel display (this time it’s AMOLED, like on the Lumia 928) with super sensitive touch.
The handset also features the same old dual-core Snapdragon S4 with 1GB of RAM, a configuration that sounds decidedly mid-range nowadays. The camera looks like the same 8.7-megapixel one with a optical image stabilization and Carl Zeiss lens. It’s also got Wireless Charging and it also makes the phone thick as you have to dress it in a special case.
The Nokia Lumia 925 is basically on many levels the same old Nokia Lumia 920 but without its heft and bulkiness, and with a sleeker camera interface. Nokia calls it Smart Camera and plans to bring it to all other Windows Phone 8 Lumias. Is it worth upgrading to the Lumia 925 now? Probably not, but for new users wanting to explore Windows Phone this seems like the new standard.
And here is a recap of the Lumia 925 features and spec highlights.
