Call Quality

With its signature speakers, there’s no issue trying to make out voices in even the noisiest of environments.

As the earpiece is actually one of the stereo speakers, it really lends some help in the calling quality performance of the phone. Not only are voices exquisitely loud and commanding, but they’re for the most part clear and noise-free – making it very easy to hear our callers in extremely noisy environments. Lucky for us, that’s also the case switching it to speakerphone mode, where its dual front-firing speakers deliver a potent mixture of power and clarity. Lastly, our callers also benefit by being greeted to voices on their end of the line that are robust and lively.


It’s a pretty decent performer from the looks of it, though, its battery size is smaller than those of its main rivals.

As an indirect result of sporting a larger screen this time, the new HTC One also sees its battery size increased. Specifically, it went from a 2300 mAh one last year, to a slightly juicier, 2600 mAh battery. Compared to other recently announced flagship phones, the capacity still pales when you consider the Galaxy S5’s 2800 mAh battery and the even larger 3200 mAh one stuffed in the Xperia Z2.

Regardless of that, it’s more than enough to get us a solid one-day of normal usage – and that’s with the HSPA+ connectivity of our particular unit! Going through our synthetic battery life benchmark, the HTC One (2014) has lasted the impressive 7 hours, which puts it in the same league as some notable performers, such as the LG G2, or the gargantuan HTC One Max. In comparison, the old HTC One's result is just 5:45 hours, so the new flagship will be a definite improvement in this area.

HTC has yet another ace up its sleeve in the form of the unit’s ‘extreme power saving mode.’ Depending on what battery level you have the phone set to activate the mode, battery life will be extended tremendously. Under these extreme conditions, the handset only permits us access to the bare essential functions – like phone calls, text messages, and manually receiving email. For example, even with 10% battery capacity, the extreme power saving mode will provide roughly 30 hours of standby.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

hours Higher is better
HTC One (M8)
7h 12 min (Good)
6h 48 min (Average)
LG G Pro 2
6h 48 min (Average)
Sony Xperia Z1
4h 43 min (Poor)
5h 45 min (Average)


HTC isn’t wasting any time in getting its flagship out and into the hands of hungry consumers. In just a short time, we’ve witnessed the unveilings and announcements of several flagship smartphones, but it’s comforting to see that HTC is aggressive with the new HTC One’s rollout. To the amazement of many folks out there, it’s being made available right away for the usual $200 to $250 on-contract price point or $650 off-contract..In a field of other contending flagship smartphones, the new HTC One (M8) is blatantly outstanding for its impeccable industrial design – one that’s unparalleled thus far! Seriously, it’s one of the few smartphones that take pride in donning a stylish and solid metallic chassis - the elements needed in giving it that oh-so delicious, premium association.

Of course, the addition of a second camera in the rear helps to enhance the look of photos that are taken, but generally speaking, the pure quality of its camera is still lagging behind the forerunners in the space. Yeah, it takes some pleasant looking photos and videos, but it just can’t capture as much fine details as its esteemed rivals. Therefore, the overall feeling we have regarding the camera isn’t an enthusiastic one.

So what does it all mean for the new HTC One, the handset that the company is betting on to succeed in the face of stiff competition? Yet again, we can’t deny the obvious that it’s an amazingly gorgeous smartphone – one that we’re unlikely to see surpassed by any of the flagships being released within the first half of 2014, probably with the exception of the Sony Xperia Z2, which will be able to rival the new One's premium build. The new HTC One doesn't seem to have any particularly weak spots, save for the UltraPixel camera, which continues to lag behind rival offerings. Still, we have to make it clear that the camera is good enough for casual usage. So, it'll all come down to just how important the camera is to you. If you happen to demand top-notch camera quality with no compromises, then we think it'd be worth waiting a few weeks so that you can take a look at the upcoming Galaxy S5 and Xperia Z2, which are expected to perform noticeably better in this respect.

However, if you're ready to settle with just a decent camera, then we're sure you're going to appreciate the new HTC One's beautiful design and robust set of features and capabilities.

It could of been worse. With the same 4 UltraPixelated camera they should of been deducted 2 points.

We have to wait for camera comparison first. Because they have done improvement in their ultra pixel camera.

What kind of improvement? You mean that childish faux bokeh effect? 2 minutes in any photo-app and I will do a better one. Certainly one of the biggest gimmicks of smartphones in 2014...they should have used a different camera tech because Ultrapixel was outdated and pathetic either last year.

I don't understand how not being waterproof lowered the review though, Id take this over flaps all over the place. I'll wait and see if they'll treat the next iPhone the same way because I'm pretty sure it won't be waterproof.

It wasn't a con until sammy got involved in the waterproof department, PA are awesomely biased...

They've had a review unit for awhile like most of the websites have.

62. AppleHateBoy unregistered

I know that. The question is how come they got 2 of them?

They made the videos before hand and posted them together. Seriously how hard is it to get that.

BIG FAIL Phone. Move it there's nothing new to see here. the best phone so far this year Galaxy S5, no doubt . .

Eh? What new does the GS5 bring that make it stand out (that aren't gimmicks no-one uses) then? Another uninspired piece of plastic to add to the thousands already flooding the market, at least HTC are TRYING to make their product stand out. Samsung rely too much on the fact that millions will blindly buy it anyway...

I'll admit the camera features of the M8 are pretty gimmicky though.

96. iushnt

A better camera..screen with 2nits lowest brightness and 500nits+ highest brightness, water and dust resistant, download mode merges LTE and WiFi, two WiFi antennas for better connectivity.., ultra power saving mode makes the screen black and white and only allws limited number of apps to run, also heard rate sensor is better than having 2_cameras at .. the m8 is just ahead in design and nothing else

I know that the HTC One wasn't a huge leap in specs (yet neither was the s5) but they at least seem keen to innovate or try and change things. If the galaxy s5 wasn't the same (very similar) plastic slab, I would agree with you. I'm not saying the s5 is a bad phone, just simply that samsung seem to be getting complacent...

Very well put, you just sold me on the GS5 and I have the GS4. I was looking for something different this time but after the camera let down on the M8 I now realize that the upgrades the GS5 has are very useful; dual wi-fi antennae, download booster that merges LTE and wi-fi and a upgraded camera. Those are the 3 most used features for me. I really don't care if it has a metal or glass or plastic housing as long as it's well constructed.

well said.. but i dont agree its ahead in design too.. Comapare the dimensions and weight of m8 with s5. S5 is significantly smaller and lighter even though it has a bigger battery. If design means only looks then it acceptable but i dont think thats the case.

102. Droiderr

Posts: 35; Member since: Mar 05, 2013

to name a few: 1. finger print scanner 2. heart rate monitor 3. water resistance 4. better hardware and camera 6. lighter and smaller with same screen size. now go figure!!

Maybe if you like Touchwhiz, which personally I think is garbage. Not to mention the bloatware.

How come this HTC One M8 only gets 8.8 while iPhone 5Crap got 9.0? We know HTC One M8 is obviously not the best phone out there. But still at least it's much better than iPhone 5C in every way. The only three things let me down are stupid logo placement, really huge size compared to other 5" phones and of course camera.

How is it that the battery, that according to them lasted longer than the G2, which is also bigger is not a"Pro". Same goes for the 128Gb so card slot. Really, really????

Did you look at performance? Did you look at photos? Did you look at size, weight (BIG!) vs. screen size and battery size (moderately small)?

50. true1984

can someone explain the weight thing to me? i don't see the big deal as long as i dont get a workout lifting the phone.

I agree that the phone is a little on the large size but the BoomSound speakers have a lot to do with that. Regarding the battery... Please tell me what matters more, the size or how long it lasts? Last year's One had a smaller battery than the S4 but lasted longer.
