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.

    If a 64 GB uSD card makes you happy, you might have problems.

    Biggest logical fallacy is to claim that there is no need for affordable storage options in smartphones when the OEMs are charging $100, $200, $300 extra per those extra storages, and apparently the reviewer doesn't see the irony of it. If no one needs more than 16 GB, how do the OEMs get away with such ridiculous markups?

    The reviewer is happy as clam as long as she gets a new phone every other week.

    Yes, they're going away, slowly but surely, except they're not and in this case a device-maker that didn't include SD slots before added it to their latest flagship phone? How can you claim logical fallacy and not realize the inaccuracy of what you just wrote? Do you think next year's HTC One update will include an SD slot or no?

    As for the rest, it doesn't matter what the majority of disinterested users want, like any industry, the demand of the top-end drives demand and innovation for the rest. Just as most people may not care for a microSD slot, removable battery, or unibody aluminum chassis, they will ALMOST CERTAINLY take the advice over which phone to pick based upon the input from someone who DOES care about those features, or has the phone and decides on it based on word of mouth or first hand exposure.

    Dear Anand(Tech),

    No love for Xperias? Saw every brand are accounted for here, except Sony ;-)

    Because Sony want proved a demo sample. Blame your shitty manufacturer for that one, Sparky

    You have the HTC One Mini listed as a quad core Krait 200. Isn't it actually a dual core, and isn't it actually Krait 300, being that it's MSM8930aa?

    You're not the first person to claim the One Mini has a plastic speaker grille, but to me seeing it in person it is clearly metal, albeit with one of those clear plastic coatings like aluminum food tins usually have on the inside to protect the food. What's the deal - what makes you claim it's plastic? I agree it doesn't look great like on the One, but it quite clearly is metal albeit with a lower grade finish.

    For god shake, put snappy dragoony 800 in it already. And please, anything lower then 8MP is budget phone category. ultra pixel is useless. try capture a document and Ye shall know the difference. speaker at the front are welcome thou.

    am I the only one laughed out loud at the speakerphone volume graph.... (beats off)

    Would of made much more sense to go with the SD 800. SD 400 on mini SD 600 on One and SD 800 on max. The SD 800 actually has better battery life due to LTE integration and it's faster. I can't bring myself to buy an outdated SoC when phones are already outdated so fast. Buying anything less than a SD 800 is a foolish move.

    I was really pumped about the max. But the SD 600 ruined it for me. I've been let down constantly. Was pumped for the lumia 1520 but of course t-mobile isn't getting it. I was pumped for the note 3 but it was barely an upgrade from the note 2. There is nothing good enough to make me want to add 23 dollars a month to my bill to subsidize a phone when my G note 2 is fully paid off and I get pure unlimited everything for 69.99 with LTE activated in my area. Looks like my note 2 will be my trusty side kick another year. Hope the note 4 brings something great to the table.
