For a glossy plastic bodied thing, it’s surprisingly attractive, slim for its massive size, lightweight, and solidly constructed to give it some substance.

Reviews Word on the street for the HTC Desire 820


8.0
Now that Android 5.0 Lollipop is beginning to make its rounds, we’re eager to see the Desire 820 benefit from all of the update’s rich new features, but who knows when that’ll come to fruition.

What People Are Saying Give it to me straight

Screen

In particular, it emits a stronger brightness output of 543 nits, and has a better average gamma of 2.19, which is really close to the 2.2 reference.
by PhoneArena (Nov, 2014)
On paper, it looks like HTC didn’t change a thing with the Desire 820’s display, seeing that its specs match the Desire 816 – so what we get is a 5.5-inch 720 x 1280 LCD display.
by PhoneArena (Nov, 2014)
Notable for its 64-bit architecture, the Snapdragon 615 chipset is a nice touch that gives the phone notoriety, but its true potential has yet to manifest.
by PhoneArena (Nov, 2014)

Cpu

So far, there’s nothing greatly unique about the Desire 820 that we haven’t seen before in other handsets, but it’s a noteworthy smartphone for the simple fact that it’s powered by Qualcomm’s 64-bit based octa-core chipset – the Snapdragon 615 SoC, where each core clocks in at 1.5GHz.
by PhoneArena (Nov, 2014)
Well, that’s where the HTC Desire 820 comes into mind, as it bears an impressive piece of silicon in the form of a potent 64-bit octa-core Qualcomm Snapdragon 615 processor.

Camera

It’s an effective amount on our particular review unit, which has a slick contrast due to the blue accents around its edges and camera lens.
by PhoneArena (Nov, 2014)
One of the few complaints we have has to do with its color reproduction, as images tend to look a bit dull at times, with colors lacking that particular vibrancy that could make them appear vivid and lively.
by PhoneArena (Nov, 2014)

Apps

Sure, it handles all sorts of tasks without much fluff, including some 3D gaming, but its true potential will hopefully manifest once it’s treated to that Lollipop update.
by PhoneArena (Nov, 2014)
What’s especially important to mention here, though, is how the experience of the Desire 820 doesn’t necessarily adhere to the requirements we’d want to get from a phablet – like optimized layouts amongst its native apps to make use of the larger real-estate.
by PhoneArena (Nov, 2014)

Battery

Although it’s tough to pinpoint the exact reasoning behind it, the Desire 820 is able to churn out slightly longer battery life than the Desire 816 before it – and that’s knowing it’s outfitted with the same capacity 2600 mAh battery.
by PhoneArena (Nov, 2014)
In our battery benchmark test, it achieves a mark of 6 hours and 49 minutes.
