The good: Nokia's Lumia 925 has a sleek, slim, partially aluminum build. Its camera takes great shots, especially in low light conditions, and the LTE smartphone comes in at an affordable price.
The bad: The Lumia 925 is a little wide and squat, and sharp corners diminish handheld comfort. T-Mobile's version has 16GB of storage instead of 32GB.
The bottom line: Nokia's lovely Lumia 925 delivers a high-end Windows Phone experience, but camera snobs with deep pockets should hold out for AT&T's Lumia 1020.
Of the three phones in Nokia's U.S. Lumia 920 lineup -- the
Nokia Lumia 925 for T-Mobile,
920 for AT&T, and
928 for Verizon -- T-Mobile's 925 has the best hardware, hands down.
Slimmer than the rest, it's also made with premium aluminum elements and has a tight fit and finish that approaches the pristine finesse of HTC's One. Nokia pumps up the buttoned-up feel by backing off the Lumia's screaming colors and muting the palette to white, black, and gray -- T-Mobile has it in white. A few design quibbles chip away at the effect, like edges that seem sharp despite the phone's curved spines.
A competent camera with terrific low-light performance backs up the rakish design of this global flagship, which has the same OS and apps as the other Lumia 920 phones. Unfortunately for it, the 925's stay at the top is short-lived and already overshadowed by AT&T's forthcoming
Lumia 1020 and its 41-megapixel camera. Still, T-Mobile customers should feel smug with this great-looking Windows 8 phone, which costs $49.99 down and $529.99 all in.
Design and build
Silvery aluminum trim frames the 925 in the first Lumia to use metal, but the matte plastic backing lashes it to the Lumia family of unibody polycarbonate phones. The design looks good: slim (0.33 inch thick) and clean with very few gaps, and black bands on the spines for accent.
The deep-black glossy screen looks lush and deep; and on the right, aluminum buttons that control volume, power/lock, and the camera button pop out to meet probing fingers. When I hold the phone, its wider dimensions -- 5.1 inches tall by 2.8 inches wide stretch across -- can make the buttons stick out into the hand, even though I like that they're not flush. Unlike the HTC One, the 925's back doesn't bow enough to curve into your palm, so it doesn't feel quite as snug.
Nokia's metal Lumia 925 is a looker.
I did notice that the white version picked up smudges and discoloration on the back panel, but the schmutz usually rubbed away with a little water and a little muscle.
At 4.9 ounces, the 925 is substantially weighty, not wispy. The phone is a little wide for some pockets, but toss it into a deep pocket or a purse and it's just as portable as any superphone.
Like the other 920 series phones, the 925 has a 4.5 inch WXGA screen with a 1,280x768-pixel resolution. It has the ClearBlack filter for reducing outdoor glare, Gorilla Glass 2 for scratch resistance, and a sensitive touch screen you can navigate with long fingernails or gloves. The AMOLED screen technology means colors pop bright and blacks look rich and deep. Microsoft's graphical Windows Phone design looks great in this treatment, and so do photos, videos, games, and images on Web sites.
Nokia grouped the ports at the top to keep the left spine and bottom clear. Volume, power, and camera controls live on the right.
Below the display, Windows Phone's three capacitive buttons handle navigation and pull up extra tools, like voice search and task-switching. Above it, you'll find the front-facing camera. Nokia has been making phones for so long, it's a little disappointing that the 925 and other Lumias lack an indicator light on the front to clue you into charging status and alerts.
Keeping it classy, the 925 groups its headset, charging, and Micro-SIM card ports up top. On the back, the stylized camera module pops out slightly, topped by a dual-LED flash.
OS and featuresRunning
Windows Phone 8, the 925's software doesn't deviate from the other Lumia phones. There's NFC support, Bluetooth 3.0 (which could soon
turn into Bluetooth 4.0), and the whole host of connectivity and OS features.
One difference from the 920 and 928 is that there's no integrated wireless charging, which is part of what makes this phone slimmer around the midsection. Instead, you can purchase an aftermarket snap-on cover, which does come in screaming colors if you miss them.
On the apps front, Nokia continues to give its phones an edge with the OS, offering up a heap of Nokia-only apps and services, like Music Mix radio. Its Here maps app just recently made the jump to all Windows phones, not just Nokia's. You can find more details on Nokia's apps in the
Lumia 920 review.
Camera and video
With each new Lumia 900-series phone, Nokia has subtly changed and incrementally improved the camera's image quality. Like the rest, this one has an 8.7-megapixel lens with PureView processing algorithms.
Instead of the 928's Xenon bulb, the 925 returns to LED flash; two of them, in fact. This time around there's a sixth lens in the Carl Zeiss optical assembly, which Nokia says will take clearer daytime shots. In addition, you have a backside-illuminated image sensor, autofocus, and 4x digital zoom.
The camera app is pretty plain by default, but like all Nokia phones, it includes lenses for panorama and Nokia Smart Cam, which adds a load of effects you also see on top Android phones. You'll be able to edit photos as well.
This 8.7-megapixel shooter has a sixth lens and great lowlight capabilities.
I was happy with most of the photos I took on the Lumia 925. They were bright, sharp, colorful, and detailed. Not every image packed in every detail, and some sunlit conditions would overwhelmed all the smartphone cameras I used.
Nokia continues to dominate the field in the quality of low-light shots that it takes. Even in very dark rooms with uneven lighting, the Lumia 925 uses its focus flash and image chips to the best effect, with HTC and the iPhone 5 a close second, and Samsung trailing behind, even when set to night mode.
The Lumia's 1080p HD video recorder also produces high-quality video that's smooth, colorful, and an adept tool to tell a visual story. For its part, the 1.2-megapixel front-facing camera adopts a wide angle, and shoots in 720p HD video. The latter is great news for video chatters like me, and the wide angle should help with those selfies.
Exposure on the self-portraits can be a little off at times, with your face looking one color and the rest cast in another. Overall, though, the images were usable.

Call qualityNokia phones typically offer up high quality call quality and clarity, and the 925 (CDMA 850/900/1800/1900MHz) mostly stays the course, despite a few bobbles in my
San Francisco tests.
Volume was strong on level 5 of 10, but voices weren't entirely clear on my end. For example, my main calling partner was intelligible, but didn't sound quite as sharp or as natural as usual. In addition to that, his voice sounded somewhat lispy and muted, almost gauzy. Still, we were able to carry on a long conversation and the line was completely clear of white noise, blips, and beeps.
On the other end of the line, volume was loud and strong. My audio came over a little distorted and mushy, my caller said, and sounded a bit flat and a tinge unnatural, maybe raspy, but not unpleasant. Again, background noise was kept at bay. He rated the phone a B+ for audio, not the top of the line, but a strong experience overall.

Spreakerphone was also strong when I held the phone at hip level. Volume dropped immediately and I had to increase it all the way to 10/10. Voices sounded really tight and clean, without a lot of echo or fuzziness. There wasn't even a hint of background noise. Voices did acquire a strange robotic quality, and a little of the phone's formerly lispiness remained. Still and all, a great speakerphone.
My test partner agreed that volume dropped, but said he liked the quality. I still sounded a little mushy, and the phone did nothing to suppress echoes, but he didn't hear any distortion and felt comfortable speaking for some time.
Performance: Speed, processor, battery life
The Lumia 925's 4G LTE performance is only as good as T-Mobile's network in your area. Here in downtown San Francisco, it's a reliable double-digit Mbps experience down and slightly less up.

The Lumia 925 uses the same processor as its siblings, Qualcomm's 1.5 GHz dual-core Snapdragon S4 chipset. It's plenty snappy, although certain things do take a few beats to open. Pretty much every Windows Phone handset I've used takes a few seconds to load the camera app, for instance, and the method of capturing a photo on the native camera app stalls shot-to-shot times, which means you could miss what you're looking for.
Overall, I can't complain about the phone's navigation or data speeds.
Battery life on the Lumia 925's 2,000 mAh battery seems fairly standard, especially since it's the same ticker behind the 920 and 928. It has a rated talk time of 12.8 hours and a rated standby time of 18 days. We'll do some internal battery drain testing ourselves as well.
Note that a phone's battery degrades over time, so these numbers represent the best you can expect in the phone's lifetime. In general, batteries generally carry you a full work day before requiring a complete charge.
Storage space is a bit of a sore point for some with this device. Globally, it sells at 16GB or 32GB capacities, but T-Mobile's model caps off at 16GB internal storage with 7GB of free online storage with Microsoft SkyDrive. That's generally enough space for average users, but since theres's no expansion slot on this device, people who typically download tons of videos and games may run into problems. The 925 has 1GB of RAM.
Who should buy it?
Physically, Nokia's Lumia 925 is a sleek, good-looking, tailored device that proves Nokia is adept at making phones with understated elegance, not just statement pieces. Indeed, Nokia has had a long history with design, and its chops show.
The fact that the 925 also backs up its hardware with Nokia's software apps and services goes a long way toward making this the top Windows Phone...this week. With the
Lumia 1020 and its 41-megapixel camera looming (an AT&T exclusive in the U.S.), the 925 will look weaker in comparison, especially with only 16GB of storage for photos and videos.
There's also the question of Windows Phone as a platform. It's weaker in terms of capability than Android and iOS, it doesn't have quite the same amount of top-tier apps (though Microsoft has advanced on this tremendously), and it isn't as graphical to behold. Not everyone wants or needs the full-throttle smartphone powerhouse experience where everything is customizable, and Windows Phone has a few more tucked-away features than some folks realize.
I'd say, T-Mobile customers on the lookout for a Windows Phone device in particular or a straightforward smartphone in general should absolutely make the Lumia 925 their top choice. Those seeking a blow-you-away camera experience on Nokia's most advanced phone yet, hold out for the Lumia 1020
