Where the One M8 features a nicely curved metal body, the Desire 816 takes the form of a flat plastic slab with rounded corners. What's more, unlike the One X and the more recent E8, there's no fancy plastic unibody construction on the Desire 816, which allows it to flex ever so slightly. Then there's the size. At 156.6mm tall and 78.7mm wide, this gigantic phone certainly won't be everyone's cup of tea, but for HTC, it's a much-needed weapon to suit the Asian market's peculiar tastes. On a more positive note, the combination of the width and the matte finish allows for a sturdy single-hand grip. Even so, with that 5.5-inch display, you'll definitely need your other hand for tapping and typing.
With the metallic power and volume buttons placed on the left, your left hand will quickly become the default choice for holding the phone, which I'm fine with. What I do find annoying is that the buttons rattle slightly when the phone is shaken, and it's the same story with the volume keys on the M8. The other side of the phone is occupied by a long flap door, which reveals the nano-SIM slot (or slots, if it's the dual-SIM 3G version) and the microSD reader, which supports cards as large as 128GB. Isn't it great when you can swap out SIMs and memory cards without having to use a pin?
As with most recent HTC phones, the Desire 816 features front-facing stereo loudspeakers, each of which has its own amplifier to boost the volume -- thankfully not to the point of distortion. Of course, you shouldn't expect these speakers to replace your traditional ones, but having them facing toward you provides a better multimedia experience -- complemented, of course, by that massive, high-quality IPS screen.
Unlike the matte front face and bezel, the back is coated in a glossy finish that helps highlight the curved edges and -- though it was certainly unintentional -- the plastic panel's unevenness. As you'd expect, the gloss has a tendency to attract hand grease and scratches, but you can always slap on a case to solve that problem; and it still wouldn't be too bulky, given the phone's reasonable 7.9mm thickness and 165g weight.
For a while, I actually forgot that I was using a mid-range phone instead of a flagship.
There's nothing really surprising about the internals: They're perfectly adequate for general tasks. Having used the Desire 816 as my main phone for weeks, I can safely say that the 1.6GHz quad-core Snapdragon 400 SoC and 1.5GB of RAM let me browse the internet, watch videos and look at photos without many hiccups. Oh, and the LTE speed comes in handy as well. For a while, I actually forgot that I was using a mid-range phone instead of a flagship, and the generally smooth performance, plus the great multimedia experience, played a big part in this, despite the LCD's relatively lower pixel density of 267 ppi. And even that I eventually got used to.
There were a few things I did miss. First of all, my UK edition Desire 816 lacks an NFC radio, meaning I couldn't enjoy the convenience of sharing content using Android Beam, in which you place two NFC-enabled Android phones back to back, and then tap the content on the host device to initiate the direct data transfer. The lucky folks in Asia can get a Desire 816 with NFC, but only if it's the LTE version.
My other gripe is HTC's removal of the physical Android keys. Yes, I know, it's been like this since the M8 (which I'm still a fan of), but I'm going to say this again: Why make me tap the screen twice -- once to make the virtual keys appear, and again to pick the key -- when I could just tap once? And no, forcing the virtual keys to remain on screen would be a waste of pixels. The right thing for HTC to do is to take a page out of OnePlus' book: Let the user toggle between virtual and physical keys (though I insist the latter makes more sense). Help me, Peter Chou; you're my only hope.
Last, but not least: I miss my speedy cameras. That's right, while on paper the 13MP/5MP shooters sound generous, they're simply not for the impatient. More on that later, though.
Much like HTC's other recent devices, the Desire 816 comes with the company's Sense 6.0 UI, which is built on top of Android 4.4.2. You'll find a thorough walkthrough of the software in our M8 review, but in summary, I find this to be an intuitive custom skin that also happens to be stylish. Sense UI has come a long way since the Windows Mobile days (we made a nice gallery covering its evolution), and version 6.0 is easily its best iteration -- with much to offer.
Before we recap the phone's various software features, I want to bring up a few handy setup tools that are often overlooked. For those migrating from an iPhone, you can use HTC's Sync Manager desktop app to transfer your contacts, calendar, messages, photos, iTunes playlists, wallpaper, bookmarks and even apps to your new HTC phone, provided you have an iPhone backup file (generated by syncing with iTunes) on your computer. It's even easier if you're switching from another Android device: Just install the HTC Transfer Tool app, launch it on both devices and you'll be able to transfer pretty much everything to your HTC phone, multimedia files included. If your old phone doesn't use either OS, then you can try Bluetooth, but there's no guarantee given the messy nature of Bluetooth on older devices.
Afterward, you can use the HTC Get Started tool to wirelessly set up your phone's BlinkFeed news feeds, apps, sounds, bookmarks and wallpaper from the comfort of your computer screen, as pictured above.
Most of the M8's essential software features are present here, including the BlinkFeed content aggregator on the leftmost home screen (you can disable this, but I personally use it every day), the integrated Video Highlights editing tool (with slick effects and soundtracks), the photo-editing tools, the bundled music player's cool visualizer plus lyrics viewer, the self-explanatory Kid Mode and UI color themes. It's definitely still a fun system to play with, and it shouldn't intimidate the less technically minded, either.
Due to the lack of processing power and certain sensors, among other reasons, the Desire 816 misses out on Motion Launch, Fitbit integration, the Dot View case and some camera features (more on that in a moment). I can understand the technical limitations for those features, but not letting us set different wallpapers for the lock screen and the home screen is certainly a weird one (same goes for the One mini 2). Having said that, I've been pleased with how smooth and stable the system's been running. You'd only notice the slower speed if you're also coming from a recent flagship device -- namely, those powered by a Snapdragon 800 or 801 chip.
I've generally been quite content with the Desire 816, but its cameras can be real nuisances. Don't get me wrong: The 13-megapixel, f/2.2 main camera and the 5-megapixel front-facer deliver great detail. For both stills and videos, the main shooter does a decent job in well-lit indoor scenarios, but it has a tendency to underexpose when used in bright outdoor environments, and the dark spots are even darker as a result. It's worth noting, though, that you should be able to fix that somewhat by manually choosing a different focal point. Normally I'd try HDR as well for taking stills in this kind of situation, but on my Desire 816, it was often more of a gamble with the vibrance you'd end up getting. In my outdoor comparison HDR shots, the Desire 816 did an obviously dull job, whereas the M8 yielded a faithful reproduction, and the OnePlus One only had a slightly green bias. At night, some HDR shots taken with the Desire 816 appeared washed out.
The cameras' focusing or shutter response can be hilariously sluggish.
But HDR isn't the biggest problem on the Desire 816. What annoys me the most is the cameras' temperamental behavior: Their focusing or shutter response can be hilariously sluggish, to the point that it makes me wonder if there's a bug. Either that or the phone really has a bad attitude (which means we're one step closer to being overruled by artificial intelligence). On top of that, the shutter speed can be laggy even in slightly dimmer environments, so you might end up having to make multiple attempts, thus prolonging your suffering, before you eventually feel the urge to throw the phone across the room.
Funnily enough, both my colleague Jamie and I saw the same issue on the One mini 2, which has the same camera and produces similar images. It appears that HTC simply took away that fancy ImageChip 2 -- the speedy image signal processor used by the M8, the M7 and even the original One mini. Worse yet, the front-facing cameras are inconsistent across different HTC models. At night, my selfies taken with the One mini 2 appeared much redder than their counterparts from the Desire 816 and the M8. On the flip side, during the daytime, the same phone managed to produce the most accurate selfies among the three, with the Desire 816 taking a slightly cooler tone, and the M8 pushing the contrast up a bit too much. Never mind that the M8 still beats them all with its wide-angle lens; I'm still baffled by how HTC could let the image quality vary so much across its phone lineup.
