Obviously the highlight of the One max is its huge 5.9-inch 1080p display. After all, the huge display is literally the reason for the max moniker and its gargantuan size. It’s still an IPS LCD, and like the One, resolution is 1920x1080. Using the same resolution at larger size means lower PPI, but the One max is still high enough (373.4 PPI) that individual pixels shouldn’t be visible at all.



One interesting thing to note about the One max however is that the android display density is still set to 480 PPI, putting it in the same DENSITY_XXHIGH category as the One. This means that applications will look like scaled copies of what you’d expect them to look like on the One. There’s an interesting ongoing debate about what users really expect from these larger-sized smartphones and the demographic that’s buying them. Do users want scaled, larger applications which are easier to read, or the ability to display more content. HTC oddly enough seems to have scaled parts of their own UI, for example the widget panels are five row instead of four on the One max, and the launcher defaults to the 4x5 size instead of 3x4 which would look downright silly, further the status bar is also smaller.

I’m not complaining, it’s just interesting to see 480 in Android but the HTC apps scaled down to give more real-estate, which is what I’d prefer since I have good vision.

 

One improvement I’m really happy about in Sense 5.5 is a change to the auto brightness function. Rather than just have a checkbox, the One max will allow you to set an upper bound for the auto brightness algorithm. Ideally I would like a higher or upper bound, or a bias function (+/- some delta), but this is a step in the right direction.

Contrast Ratio

The One max display goes very bright, up to 506 nits, higher than the One or One mini. White point is also a bit more controlled than the One, at 7301 K average. My biggest complaint about the One max is that like the One it has a dynamic brightness/contrast function that adjusts screen brightness as a function of the content being displayed. That alone isn’t a huge problem, it’s just that there’s no way to disable it in the UI, which would be great, since it’s distracting watching screen brightness change as you move around the UI. I would love to see HTC go the Google approach and restrict these functions to full screen video playback, and give the option to turn it off entirely.

Running it through our display tests, it’s clear that the One max also has a bit of the saturation boost we’ve seen popping up on other phones as well. The saturation curves are great until the second to last point, which is almost set to maximum saturation. I’d love to see even more emphasis on color accuracy for the next generation of phones, the One max seems to be in the general ballpark of the One, but slightly worse.

    "I’ve said my part already on microSD cards and the fact that they’re going the way of the dodo in smartphones, I just don’t need one anymore, and definitely not at the expense of build quality. It is convenient not having to use a SIM ejector tool though, even if I carry one around all the time anyways"

    I'm sorry, you carry around a sim card removal TOOL, at all times with you, and you don't think micro SD cards are relevant any more? I don't think you are qualified to write a review about this phone if that is your opinion. I mean you would rather use a cloud/pay the extra money for inbuilt storage, than use an affordable, replaceable, micro SD card... But you paid to have a sim card removing tool, and then chose to wear it upon you? At all times?...

    I'm glad to see that you are not letting this issue with Brian's Klug's anti-local storage bias slip away. The sad fact of the matter is that most reviewers are notoriously biased. Some are biased due to ignorance, some are biased due to payoffs, many are biased due to both.

    The fact that Brian Klug has some sort of hate trip on SD cards is not surprising. All the big money players in the US want to get rid of local storage so they can (a) increase data revenues (b) mine and sell more data (c) comply with NSA directives to collect more data on people. So we have one of Anandtech's top tier reviewers going off on how bad micro SD cards are, i.e. implying you cannot build a high quality phone if it has a micro SD card. And then the same reviewer disparages the many millions of people who depend on SD cards every day as some sort of unimportant minority.

    It seems obvious to me that objectivity and balance have been lost, that the reviewer is just a tool pushing an agenda.

    I clearly am an agent of the NSA and this is a long-game to get all of your data. Clearly.

    So with the same logic laptop should get rid of SD slots too, especially macbooks with SD card sticking out. Heck, earlier macbook pros didn't have one!

    Still dissing, eh..

    I don't think what 10101010 said translates to your intelligence, lol. For one you are not really a big money player. I think what 10101010 meant is that you happily obey.

    Wow, your arrogance is astounding.

    Stop listening to your friends in the phone manufacturing business for a minute and start listening to the technical crowd that makes up the majority of your readership.

    Hey, HTC, how about the Butterfly S?

    I'm having a tough time liking the One Maxx - it's such a big phone for .2" screen increase over the Note 3, with the on screen buttons eating a decent part of the increased real estate.

    Also the Note 2 was pretty heavy, the Note 3 was a nice decrease in weight. The difference in weight between the Note 3 and One Maxx is close to the difference in weight between the iPhone 5 and Note 3.

    Well, the fingerprint issue isn't really resolved yet. We will have to wait and see how the security aspect goes. Still, my guess is that Apple is probably better at this generally than Android OEMs, specifically 2nd tier ones like HTC.

    This seems like an unnecessary review, especially as many much bigger launches were ignored. Who will buy HTC One Max? Very few people. HTC is going down anyway.

    I'm still waiting for the mother lode: Nexus 5.
    I also hope Brian can overcome his WP8 bias and review a few Nokia phones out this fall.
