Microsoft does budget phones incredibly well, and with almost an identical spec thisLumia 640 is a strong rival to the £149 Moto G if you're prepared to go down theWindows Phone- rather than Android route. Successor to the Lumia 630, the 640 adds some useful improvements, yet it comes in at the same £129 price SIM-free. Also see:Best budget smartphones 2015 and best Windows phones 2015. 

And why wouldn't you go down the Windows Phone route? A criticism of Windows Phone has long been its lack of apps. This is a situation that is improving all the time - indeed, as we'll discuss later in this review we were pleased to see one of our go-to benchmarks, GFXBench, is finally available in the Windows Store - and there are workarounds for accessing Google services on Windows Phone for which there are no apps.  

We like Microsoft's mobile OS. Windows Phone is bright, it's colourful, and it's something different to the icon-led home screens of iOS and Android, with tiles that update with information in real time. Once you've become familiar with its layout, it's really easy to use.  

Microsoft adds several of its own apps, and a key selling point of the Lumia 640 is its year's free Office 365 subscription (worth £60), which can also be enjoyed on two other devices. One of the perks of Office 365 is a terabyte of free OneDrive storage, which is handy since only 8GB comes on the Lumia 640, although there is also a microSD card slot that can accept up to 128GB. 

Compare it to the Lumia 630 and this Lumia 640 is quite an upgrade. The phones share the same 1.2GHz quad-core Snapdragon 400 chip, so performance remains distinctly mid-range, but the 640 has had a slight boost with the doubling up on RAM to 1GB. The camera loads much faster under Lumia Denim and, although it's still reasonably basic, it now features an 8- rather than 5Mp lens and adds an LED flash, while video recording is possible at 1080p rather than 720p. Microsoft has also added a selfie camera to the front of the Lumia 640, which lets you take advantage of Skype. The screen is improved too, both in size and resolution, and Microsoft has upped the still-removable battery capacity from 1830- to 2500mAh. Also see: Best smartphones 2015. 

Whereas previously you needed to pay an extra £20 for the Lumia 635 if you wanted 4G LTE connectivity, the Lumia 640 LTE can handle it out of the box. As before two versions of this phone are available: the Lumia 640 reviewed here, and the Lumia 640 XL. The XL is in essence the same phone, but with a larger 5.7in display and improved cameras (13Mp at the back and 5Mp at the front). It costs an extra £90, though, at £219 SIM-free. 

 

PRICE WHEN REVIEWED

From £13.50 per month, £109.99 PAYG or £129.99 SIM-free

MICROSOFT LUMIA 640 REVIEW: THE MOTO G OF THE WINDOWS WORLD

MICROSOFT LUMIA 640 REVIEW: PRICE AND UK AVAILABILITY 

Microsoft's Lumia 640 is very well-priced at £129.99 SIM-free, making it £20 cheaper than the latest Moto G with which it shares almost an identical spec.  

If you're looking to buy the Lumia 640 on a contract it's available from £13.50 per month, while you can also grab it on a PAYG tariff from £109.99.

If you get the Lumia 640 from EE you'll also get WiFi Calling (see What is WiFi Calling?). EE has the exclusive on the cyan Lumia 640, and its contract prices with a free phone start at £16.99 per month. At that price you get 500 minutes, 500MB and unlimited texts. 

MICROSOFT LUMIA 640 REVIEW: DESIGN AND BUILD 

The design is very similar to that of the Lumia 630 and 635, a little larger and heavier yet slightly thinner, with the same matt-finish case in black, or glossy in blue, orange or white, that sits comfortably and securely in the hand. This case is removable, but wraps around to the front, resulting in a solid feel that won't creak or flex under pressure.  

It's simple and unassuming, a slab of plastic with a slightly curved rear and rounded edges. There's a gaping hole on the rear for the small speaker, and the rear camera and headphone jack protrude just enough to spoil the Lumia 640's smooth surface, but still it's a good- if basic-looking phone for the money. 

As before the screen is covered by tough Gorilla Glass 3, with cutouts top and bottom for the earpiece and microphone. It's a larger sheet of glass, though, since Microsoft has upgraded the Lumia's display not only in size but also resolution. Whereas the Lumia 630 and 635 feature a 4.5in 854x480 ClearBlack IPS panel, the 640 has a 5in HD (1280x720) screen, which results in an improved pixel density of 294ppi. (Bigger still is the 5.7in screen on the Lumia 640 XL, although the resolution is the same at 720p.) 

As such, browsing the web, watching videos and even playing the odd game is now a far more enjoyable experience on the Lumia 640. The screen is not without fault - some backlight bleed issues are still visible - but it's a vast improvement and noticeably sharper than that of the 630. 

At the top of the screen is something entirely new: a selfie camera. And it's not the only change Microsoft has made in the photography department: around the back is an LED flash and, although the difference isn't visible, an upgraded 8Mp camera. There's still no dedicated camera button, though, and around the sides you'll find only a volume rocker and power button, headphone jack and a micro-USB charging port.  

MICROSOFT LUMIA 640 REVIEW: HARDWARE AND PERFORMANCE 

Microsoft hasn't particularly focused on performance in its upgrading of the Lumia 640. And that's fine, since the 1.2GHz Qualcomm Snapdragon 400 quad-core processor is nothing spectacular but capable enough for day-to-day use, especially at this price. Microsoft has, however, doubled the RAM to 1GB, which brings the Lumia 640's spec into line with the latest Moto G. 

Windows Phone doesn't support Geekbench, the benchmark we use to test phone processing performance, but the new Moto G recorded 345 points in the single-core component and 1182 multi-core. The difference in software will come into play here, so you can't assume the Lumia 640 would score the same results were testing possible, but in real-world use we found the Lumia 640 quick enough. Swiping between screens and launching apps still takes a second or two, but it's not so slow as to cause you pain. And the camera, in particular, now loads significantly faster - a couple of seconds rather than the six- or seven of the Lumia 630. 

Happily, our second go-to benchmark, GFXBench, is now available in the Windows Store. Both Lumia 640 and Moto G use the Adreno 305 GPU and the aforementioned 1GB of RAM and Snapdragon 400 chip, but we found slightly slower results from the Lumia 640 in T-Rex - 7.5fps against the Moto G's 11fps. If you're looking for a fast phone for gaming, compare these results with some of the monsters in our article What's the fastest smartphone 2015. 

SunSpider performance has seen a boost with the Lumia 640. While we recorded 1486ms for the Lumia 630 and 1968ms for the Moto G, the Lumia 640 recorded an impressive 1201ms. However, it's worth noting that we typically run SunSpider in Google Chrome to ensure a fair test. Chrome isn't available for Windows Phone, so our Lumia results were taken in Internet Explorer 11. 

Battery life was a concern with the Lumia 630. Microsoft has seen fit to increase the capacity of the still-removable battery from 1830- to 2500mAh, which means this phone will capably get you through a full day's use. 

In terms of storage there's still only 8GB built in, of which less than half is available, but you do get up to 128GB of expandable storage via support for microSD. Take up Microsoft's offer of a free one-year Office 365 subscription and you get 1TB of OneDrive storage too (and 30GB if you don't). 

MICROSOFT LUMIA 640 REVIEW: CONNECTIVITY 

The connectivity specs come as no surprise at this price. There's no support for the latest 802.11ac Wi-Fi, but Microsoft does include Wi-Fi hotspot, Bluetooth 4.0, DLNA and NFC. The GPS and GLONASS is assisted. One of our favourite upgrades over the Lumia 630, though, is the 4G LTE connectivity. (There is apparently also a 3G model, but the only version we've seen on sale in the UK is 4G - check before you buy.) Also see: What is 4G? A complete guide to 4G. 

MICROSOFT LUMIA 640 REVIEW: CAMERAS 

The Lumia 640 is not the best cameraphone in the world, but it's significantly better than the Lumia 630 in this regard. Microsoft has added an LED flash, which means there's an improvement in low-light photography, plus it's upgraded the sensor from 5Mp to 8Mp, which makes for sharper shots. You can see the difference between our standard St Pancras test shot captured on the Lumia 640 and the Lumia 630 below it.
