Interface and Functionality

Ah Windows Phone 8.1, it’s the same here like any other Window Phone.

In standard fashion, the Lumia 640 XL is running Windows Phone 8.1 with Lumia Denim in tow, which means it’s accompanied with Cortana integration and the entire suite of Lumia branded apps. Purists of the platform will find it familiar, naturally, seeing that the experience is identical to every other phone running this version of Windows Phone. We won’t get into the specifics of it all, but we can simply say that it’s always a work in progress – in the way that it’s still reaching, or catching up to its peers, but it definitely has that base functionality to compete.

Some people won’t find fault in a consistent software experience here, since of course, that’s the intent of Windows Phone from the start. Nevertheless, it’s just tough knowing that there are no optimizations whatsoever made to the experience that makes good use of the extra real-estate. Still, there’s comfort knowing at least that it’s on tap to receive the Windows 10 update when it comes out – peace of mind that ensures that owners won’t be left in the dust when the newest version of the platform is launched.

Processor and Memory

Just don’t try to challenge it with graphics processing.

Going with the same internals as its sibling, the Lumia 640 XL’s power comes from its quad-core 1.2GHz Qualcomm Snapdragon 400 SoC coupled with 1GB of RAM and the Adreno 305 GPU. More than an effective package, especially when Windows Phone is highly optimized, we’re greeted to the same fluid responses exhibited by nearly all phones running the platform. The only occasion when there’s some crumbling is with graphics processing, so tread carefully with certain gaming titles.

Despite the “XL” attachment, there’s no increase in storage capacity over the Lumia 640. Therefore, we’re stuck being extremely careful about what’s saved onto its 8GB of storage. The saving grace, though, is the availability of a microSD card slot.

Internet and Connectivity

Greeted with so much real estate, pages are able to load in their entirety with minimal need for scrolling vertically. With its 720p resolution, however, it makes fine text rather tough to decipher – so pinch zooming is still necessary. It’s not too bad to tell you the truth, just because the Lumia 640 XL more than passes for the occasion.

This particular unit is fashioned together to work most effectively on AT&T’s network, but it’s more than compatible to surf the various 4G LTE networks around the world with its diversified LTE band support. In addition, it features a-GPS with Glonass, Bluetooth 4.0, 802.11 b/g/n Wi-Fi, and NFC.

Only thing that is a turn-off for me is the old SD 400 chipset, but everything else is looking great so far. I am thinking of buying this phone, after selling my current one.

It's def. not a gamer-phone, but Microsoft has done an outstanding job getting WIN Phone OS to run far better than Android with Snapdragon 400. Recent Consumer Satisfaction survey placed Lumia 635 & 640 at top overall among new phones purchased in past year!

Yeah, I wasn't expecting it to be a gamer phone, but a newer chipset would be nice. They have used the 400 quite a lot on different Lumia phones and it is quite dated. A minor flaw, but everything else rocks. That's just me.

I honestly would recommend you looking at getting a Lumia 1520 instead. Just about everything on it is better than this phone and on eBay you can find one that is in excellent (sometimes even brand new condition) for about $250, which is the same price as this phone. Also, I'm fairly certain the 1520 is going to receive the Windows 10 update as they used the device to demonstrate Windows 10 a few months ago.

Color Temperature, Tint, and Saturation are adjustable in Windows Phone "Display" settings... Which color settings were used for measurements quoted in this review?

Did you read the review or even bother to look at the score before you made this inane comment?

If only Microsoft could get the price/value right like this for all of their devices. This is a really great value at $199. I wish MS has a similarly good value at $399.

Not trying to start an OS war but this phone getting an 8 and the Zenfone 2 getting an 8.3 is crazy. I owned the Zenfone 2 and I currently use the 640 (not much different than the XL). It's not that close. Besides that I have to say the value for the 640 is extremely good, the perfect back up phone. the best phone for $100-$130 range.

IMO this should be 8.5-9. There is simply nothing wrong with it. I highly doubt the effectiveness of their custom script, only because other sites get nearly 9hrs of video off the phone. Higher than the 7hrs custom script.

Again antutu benchmarks of WP been compared to Android you even read what says in antutu app? And I'm pretty sure that there's also blue and green colors available for this phone.

Does PA even do proper research anymore? Black and white choices only? No, that's half of the available choices. Wonder what else they get wrong with everything else...

Available "color choices" will vary by Country and Carrier. If the color you prefer isn't included with the phone, you can order it as an accessory thru Microsoft or eBay...

hmm if you are a big phone fan this one is not a bad one to get. . if only you could use a surface pen with it could be a more useful device for sure

Sure, and if they had thought to include a Taser, Cortana could also double as a nanny... (My point being -- with a $250 USD price point, the features & performance of the entry-level 640 XL phablet already make it a 'phantastic' value; Microsoft isn't overlooking the high-end phablet market, and the 1st "Continuum" phablet from M'soft will stretch the definition of "Smartphone" further than it has ever been taken before... Can you hold your breath 'til March?)
