A new leaked image popped up online, allegedly showing for the first time a prototype Nokia Lumia 950 Windows Phone smartphone.

The rumor mill is always busy churning with all kinds of leaks, rumors and speculation, and many times it's difficult to determine which are true and which are utter nonsense — but this one seems interesting.

The leaked image of an alleged Nokia Lumia 950 prototype popped up in Windows Phone Central's inbox, courtesy of an anonymous tipster the publication can't and won't vouch for. It may or may not be real, so take things with a grain of salt.

As WPCentral points out, the handset itself looks quite legitimate, but some discrepancies such as the Windows Phone logo/button area raise some questions. The leaked image also comes with some intriguing details about the alleged device.

Nokia Lumia 950 Alleged Specs

According to WPCentral's tipster, the purported handset bears the name of Lumia 950, recalling Nokia's N95's glory days, part of a "nostalgia/ 'getting back to roots'" campaign Nokia allegedly planned.

The Nokia Lumia 950 will allegedly sport a 1280 x 768 resolution, with no plans of 1080p support for Windows Phone 8 anytime soon. While some may see this as a drawback, the tipster says it's actually a good thing, as the main strength of this device is battery life. The usage of an AMOLED version of the PureMotion HD panel of the Lumia 920 seems to back up this claim.

Nokia also made some advances in terms of battery savings lately, particularly in its Asha 3310 unveiled at the Mobile World Congress (MWC). The Nokia Asha 3310 is a feature phone with an impressive standby of 30 days. Nokia may expand that technology to its Lumia lineup as well, but that doesn't mean the Lumia 950 rumor is true.

The purported Nokia Lumia 950 will allegedly not pack a 41-megapixel sensor, but it will reportedly be larger than that of current devices, offering "lossless zoom," low-light performance, oversampling and video stabilization with a Xenon flash. The handset will also allegedly have 2GB of RAM.

The accuracy of such leaks is always hard to determine, and until Nokia officially confirms or denies it, the allegedly leaked Lumia 950 remains in the rumor state. The image itself looks real enough, save for the Windows Phone logo. On the other hand, that logo is obviously a sticker, similar to pre-Lumia 800 prototypes.

The alleged specs and details, meanwhile, are not groundbreaking, which might make the story more plausible. It doesn't guarantee the leak is authentic, but it does make it more likely to be true than if it mentioned some out-of-this-world futuristic specs. What's your opinion on this? Does this alleged prototype of the Nokia Lumia 950 look real or fake?
