You can flip the viewfinder around to take photos with the 1.2-megapixel front-facing camera. Photos are fine, but understandably less clear and sharp. You'll mostly use it for video chats if you're anything like me. You can also record yourself in 720p HD.
When it comes to storage, you'll find 8GB onboard, plus 7GB free online space with Microsoft Skydrive. That microSD expansion slot will keep you in movies, music, and photos for a long time -- it holds up to 64GB. The phone also has 1GB RAM.
I tested the Lumia 810's call quality in San Francisco using T-Mobile's network (GSM 850/900/1800/1900MHz.) The overall experience was definitely above average. Volume was sufficient at a middle setting (6/10) and the call was pretty clear. When I closed my eyes and listened hard, I heard a very faint persistent white noise in the background -- certainly not enough to detract from a call. Voices also sounded natural, and I only heard two minor blips of distortion that I really only noticed because I was listening for them.
On his end, my test call partner (who chatted from a landline) mostly agreed with my take, but noticed more distortion. He also said that I sounded a little scratchy, but thought the call was overall very good.

Holding the phone at waist level, it was immediately clear that speakerphone was more distant and less clear than speaking regularly. There thankfully wasn't any of the buzzing that I sometimes feel in my hand while holding a phone. While voice quality was definitely tinnier and more hollow, Nokia managed to keep the amplification under control.
On his end, my testing partner said the Lumia 810 offered up an above-average listening experience that didn't magnify the normal amounts of echo that come hand-in-hand with the feature.
The Lumia 810 revs as its engine the 1.5 GHz dual-core Qualcomm Snapdragon S4 processor, the same chipset that's also found in such phones as the Lumia 920 and the Samsung Galaxy S3. Navigation was smooth and fast, though the phone does take a little time to boot up. T-Mobile's HSPA+ 42 speeds were also acceptable.

Windows Phone OS doesn't lend itself to a superfast bootup time, and the camera takes its time focusing before taking a shot.
A 1,800mAh battery powers a rated battery life of 10.2 hours of talk time over 3G, 15 days of standby time, and 54 hours of music playback. We'll continue to test battery life in our CNET labs and will update with more details. The Lumia 810 has a digital SAR of 0.83 watt per kilogram.
If you're deciding between the Nokia Lumia 810 and the HTC Windows Phone 8X for T-Mobile, the Lumia 810 is both less expensive and also has a few more software enhancements such as Nokia Music and Nokia Drive. However, if those whistles and bells don't stir your imagination and looks could tip the balance, choose the HTC Windows Phone 8X. I prefer using the latter on a day-to-day basis, though I would miss some of the Lumia's extra features.
If you're interested in Windows Phone and the carrier is unimportant, the Nokia Lumia 920 is the most advanced you can get, though it also suffers from a thick build.
A lot of you may wonder if it's worth switching from an Android phone or an iPhone to Windows Phone 8. It boils down to personal preference and to what you look for in a phone and in an operating system. Each OS comes with its own strengths and weaknesses; you'll have to consider the trade-offs with each. In general, though, this might help you decide.
Consider buying the Lumia 810 if you:
- Like Windows Phone 8's big, bold interface
- Enjoy a large, clear screen
- Rely on turn-by-turn voice navigation
- Want additional microSD storage
- Want to seamlessly sync with Windows 8 and with Office 2013
- Own an Xbox
Skip the Lumia 810 if you:
- Prefer a light, slim phone
- Want a mountain of apps and games at the ready
- Seek granular photo control
- Rely on voice dictation for composing e-mail and notes
- Live in Google's or Apple's app ecosystem
