Since Microsoft's purchase of Nokia in 2013, they have been busy cranking out colorful smartphones that just so happen to be on the lower end of the cost spectrum. The Lumia 640 XL is the bigger brother to the Lumia 640. As the XL in its name suggests, the Lumia 640 XL is large measuring in at 6.2 inches x 3.2 x 0.4 inches though it only weights 171 grams. Despite its large size, reviewers found the 640 XL comfortable to hold though it did require two handed operation. In keeping with the rest of the Lumia lineup, the 640 XL comes in five different color options: while gloss, white matte, cyan, orange and black. Besides the bright color options, not much stood out to experts. In fact, describes it as "inoffensively generic" while others add it feels like a budget phone. Still, they were impressed with its solid workmanship.

The reason for the 640 XL's large size is due to the 5.7-inch, 720p IPS display. While it isn't full HD, the 259ppi pixel density was sharp enough that critics needed to look very closely to see individual pixels or anti-aliasing effects. More importantly, they found the screen offered excellent brightness, great viewing angles and good color accuracy. As well, they add the ClearBlack technology offers excellent contrasts and deep blacks. It also comes with an ambient light sensor that adjusts the brightness based on your lighting situation. Protecting the screen is a layer of Gorilla Glass 3. While this does help prevent scratches, reviewers also note it is highly reflective especially in bright light situations.

To keep the phone humming along smoothly, Microsoft has opted for a quad-core 1.2GHz Snapdragon 400. While not the latest processor in its class, it is a step up from other competing budget smartphones. Paired with 1GB of RAM, the 640 XL performed well enough for most reviewers. They navigated smoothly throughout the interface with no hiccups or lag. With that said, they did notice some stuttering when multi-tasking. Overall, however, their experience was very smooth even when they fired up processor intensive games. Unfortunately, it does only come equipped with 8GB of internal storage though it has a microSD slot that accepts up to 128GB. Behind the removable back cover is the 3,000mAh replaceable battery, though reviewers don't think you'll need to swap it out that often. They were able to get 9 hours of heavy use from it though they still did need to charge it nightly.

The 640 XL comes with a 13MP rear camera. While not the best shooter on the market, reviewers were able to take decent shots in good lighting situations though Tech Radar noticed they were "a little under-saturated and noisy when you get right down to the details." Low light pictures managed to impress reviewers thanks to the integrated LED flash. While it might not be able to hold a candle to the iPhone 6 picture quality, when they compared it to similarly priced Android smartphones the 640 XL camera offered much better pictures and customization options.

While not a perfect phone, reviewers think the 640 XL is worth a look. V3 states, "…it ticks all the necessary boxes for a solid business phablet…" Neowin adds, "…the Lumia 640 XL is very, very good indeed."

Fast, functional phablet on a budget

from N4BB
Microsoft has packed an impressive amount into this entry level phablet. It doesn’t stack up well against powerhouses like the Galaxy S6 Edge+ or iPhone 6S Plus on paper, but it also comes in at more than half the cost. If you’re looking for a well performing phablet on a budget, Lumia 640 XL delivers a great deal of value. Battery life alone is worth the price of admission... Full review

It’s a perfectly competent first or even second smartphone

from GottaBeMobile

Microsoft dropped some extras with the Lumia 640 XL LTE. In particular, I’m not thrilled with the lack of a physical camera button. Forcing users to buy a separate cover to get wireless charging isn’t awesome either. Both complaints are the result of owning a Lumia before.

The Lumia 640 XL LTE is a terrific phone otherwise, and a serious bargain at $249.99 without a two-year contract. It feels great in the hand and the screen is spacious and gorgeous. Pictures and video are decent enough too.

I absolutely recommend this phone to anyone. Check to see if the Window... Full review


Should be priced at under $200 to really be competitive

from Pocketnow

The Lumia 640 XL has a great set of features for its $249 price tag. It’s disappointing that the battery cover could get bent out of shape so easily though, and it’s also disappointing that there is no Qi wireless charging capable battery cover available at this time. You’ll also want to get a MicroSD card since it only has 8Gb of storage. Personally, if you’re in the market for a Windows Phone 8.1 phablet, the Lumia 1520 can still be found new for less than $300. That phone has a better camera, better glance mode, wireless charging options, more storage, better flas... Full review

A solid Windows phone

from Tom's Guide
Anyone who likes Windows Phone and has been dying for a huge canvas with which to use it will like the Lumia 640 XL. Its 5.7-inch display shows off the Live Tile interface of Microsoft's mobile operating system well, and makes it easier to do things like type messages and notes, as well as watch videos and view photos. The biggest drawback is its below-average battery life. If you want a smartphone that lasts all day and provides better overall performance, we'd recommend the $249 OneTouch Idol 3. But the Lumia 640 XL is a solid phablet for Windows Phone enthusiasts... Full review

An inexpensive phablet that runs Windows Phone

from Phone Scoop

The Lumia 640 XL is, by and large, a great phone. It's attractive, well-made, and performs well for a $250 handset. I wish the screen had more pixels and I wish call quality was a bit better, but these aren’t deal-breakers. Windows Phone runs perfectly on the 640 XL, and Microsoft's core apps are quite good if you need to pair the 640 XL with your work environment. The camera does a great job, (as is often the case on Lumia handsets.)

If you're in the market for a Windows phablet, the Lumia 640 XL is "extra likeable" and I recommend it. If you want something a bit more com... Full review


Refreshing balance of value and performance.

from PhoneArena

Windows Phones in general are in short supply, which means that we’re more accepting of phablet-sized ones even more, especially when they’re even rarer to find in the wild. Far from being a specs beast meant to tackle on the big names in space, the Microsoft Lumia 640 XL carries a refreshing balance of value and performance.

On the pricing front, it’s being sold through AT&T here in the US for $0.99 with a 2-year contract. As an alternative, you can snag it sans contract by plopping out $249.99 to get it outright. That alone is within the threshold of its comp... Full review


A pretty good device for a mid-ranger

from Softpedia

Lumia 640 XL is a mid-ranger that’s in its essence a perfectly balanced device. It doesn’t impress, but it doesn’t disappoint either. It has a decent price, a decent camera, a decent screen, and a more than decent battery life. It boasts the typical smartphone feature lineup, with all the things that you’d expect to find, and also features a front-facing camera for selfie aficionados out there.

Overall, it’s pretty clear that for a mid-ranger, the Lumia 640 XL is a pretty good device. But for those looking to get more than that, they might have... Full review

This phablet lives up to its promises

from Digital Versus
The technical specs of the Lumia 640 XL might not seem up to much, but Microsoft clearly knew what it was doing. The phablet runs perfectly and is great for day-to-day use, whatever you need your phone for. Of course, the handset has its faults, but none of these is a real handicap. If you're looking for a phablet offering great value for money and you don't mind not having the very best screen resolution, the Lumia 640 XL should be high on your list... Full review

A better-equipped smartphone

from Fone Arena

Microsoft introduced seven new models in its Lumia 640 series. The best variant among them is the Lumia 640 XL Dual SIM and if you happen to have big hands, then you’ll like handling the phablet. The device is currently available in the market for about INR 15,200. If you are a hard core Lumia fan or using Lumia device for a while, then you’ll like the 640 XL. However, if you are new to Windows Phone ecosystem, then 640 XL leaves much to be desired.

The build quality of the Lumia 640 XL is great and we suggest you to pick a matte finish model over the glossy fini... Full review


Budget beauty

from Pocket-lint

The Microsoft Lumia 640 XL has surprised us. We've been critical of some phones in the past that seemed big with no real advantage to their size. Although larger phones are becoming more common - and the 640 XL is among the largest out there - we're quite taken with this Lumia. The performance isn't the strongest that Windows Phone has to offer, so there's some slowness in places, and the connection seemed a little weak, but that's offset by battery life that's almost unbeatable: the Lumia 640 XL is a monster when it comes to endurance.

Although the display is large, the res... Full review
