Battery life remains a huge concern for savvy smartphone shoppers. Opportunistically charging a phone and worrying about making it through an entire day with just a single charge cycle is a common complaint as well. The HTC One max addresses some of the complaints myself and others had with charging on the HTC One which charged at only 1 amp, instead the One max charges at up to 1.5 amps. Although I wasn’t sampled it, the One max box will also include a 1.5 amp charger from HTC that’s slightly taller than the previous generation. This definitely helps offset the increase in charge time that would’ve resulted given the 43 percent larger 3300 mAh 3.8V (12.54 watt hour) battery.

Device Charge Time - 0 to 100 Percent

The HTC One charges a bit faster with the latest updates, however the linear region of the charge curve is entirely dominated by that 1 A charging maximum. With the 1.5 A charging in the One max we actually see considerably faster charge times in spite of the larger battery. HTC continues to use BC 1.2 to the best of my knowledge for signaling.

To assess battery life, I ran the One max through our battery life test suite. Our battery life test is unchanged, we calibrate the display to exactly 200 nits and run it through a controlled workload consisting of a dozen or so popular pages and articles with pauses in between continually, until the device dies. This is repeated on cellular and WiFi, in this case since we have an international model of the One max that lacks the LTE bands used in the USA, that’s 3G WCDMA on AT&T’s Band 2 network. The talk time call test is self explanatory and also unchanged.

Cellular Talk Time

The results speak for themselves, the One max lasts quite a long time on battery, even with a large display. I expected the One max to lose to the Note 3 on the cellular test initially, but it posts an impressive result. I suspect display power might be the reason here between AMOLED and the more pragmatic LCD in the One max. I measured the One max with the flip case on as well, and it adds about 20 percent more battery time to the device. I'm curious to see how the USA-bound variants with LTE fare, but the One does impress with excellent battery life.

    Brian,
    Did you notice the problem that Zoes included in a highlight video now only show 1 second of motion and then freeze? I've seen that one my One when I upgraded to 4.3 and others have reported the same issue. It really seems like a bug. The highlights become much more static. All the other highlight changes are great but this is a step backward.
    Thanks,
    Mike

    I for one really appreciate that Brian has an opinion and sticks to it. He sets the quality bar high and let his opinion shine through when quality is not met.

    Speaking of quality I am happy to see that the different brands go more and more up in quality of the device and not only specifications. Of course some users prefer an easy setup and others prefer fully customized solution. Here I am sure that the latter group is far the smallest but this group still gets fully addressed by some of the biggest players in the market. This is impressive I think.

    For me personally I am sticking to my work phone, which is an old blackberry and I can live with this situation. But if I am going to put my money toward a smartphone I for one also would go for build quality. Today I am not sure which one but it would probably be a Nokia (I have owned Nokia phones before and were happy with the build quality), HTC (I for one also like the metallic casing) or and Apple (The small form factor is for me a positive thing).

    So to rap up. Brian stick with you preferences some likes some hate. But his is expected when an opinion is given.

    I can respect an opposing opinion as much as the next guy, but when it's delivered in Brian's smug, "I know what's best for everyone" attitude, it's a bit much to digest.

    I didn't interpret it as being smug. For that matter, I didn't interpret it as an opinion, either. Take his claim that microSD slots are going the way of the dodo. I think you can objectively look at how many devices include microSD card slots and conclude that it's no longer the norm in Android devices outside of Samsung and Sony, and also objectively look at how Android is engineered and conclude that they don't seem to be accommodating microSD slots in their OS design anymore.

    I don't think you should interpret this observation as an indication that Brian hates microSD card slots or something, he's just making an observation. In the case of this handset he felt that the removable back for the microSD reader compromised the design and I agree - it's heavier, bulkier and means it's no longer a gapless unibody design. But if the device had included a microSD slot on the side or something, so as not to compromise the design, I don't think this would have been a problem.

    Please stop using the word literally incorrectly.

    It should only be used when you could take the something either figuratively or literally.

    IE-

    "He blew up."

    "He got popular?"

    "No, literally he blew up. The dynamite he was carrying exploded."

    Saying a phone is literally a larger version of another phone is unnecessary. The phone is a larger version of another phone.

    "For the incredibly small percentage of users that clamors for an SD card..."

    How about the incredibly small percentage of users who obsess (for pages) over the color and finish on the phones? Oh wait - that's you guys at Anandtech.

    I just bought a smartphone with an mSD slot BECAUSE it had an mSD slot. Money where mouth is; vendors, listen up.

    I have a real soft spot for HTC. My first smartphone was the Apache, and for all its ridiculousness, I loved it. Followed by the Titan, a brief flirtation with Samsung's WinMo lineup for the Omnia, then the mighty HD2 - which is still my favourite smartphone experience due to the mad levels of developer support & fully functional Android + Windows Phone 7 ports. I've now been with Samsung for the life of the Galaxy S line, jumping on the Note bandwagon after the S III, and although I (genuinely) enjoy the functionality of Touchwiz, I'm getting sick of a few things that just haven't been fixed through three or four revisions of their software suite.

    I kept wanting HTC to make something that would tempt me away - had they shipped the international Evo 3D closer to the Galaxy S II's release, I'd have picked that up instead. Yet, for the past two years, there's been too many compromises - both the One X & the One disappointed in the battery life department above all others, something I'm not keen to compromise on. Especially so after the Note II set a hefty precedent.

    Then there's the SD card argument. Given the instability & low quality of the memory, combined with the poor and confusing experience SD cards can give consumers, I don't mind that they're going out of vogue. Wouldn't store anything crucial on something so volatile. Although in principle I wholeheartedly support user-accessible upgrades, SD slots are no excuse for insufficient internal storage, as everyone with a '16GB' Galaxy S4 discovered. For my use-case, however (Swapping between devices regularly, keeping a lot of lossless music offline, and storing backup images), an SD card slot is a definite point towards a device.

    Now, for the first time in 2+ years, HTC have made a device that ticks the most important boxes - screen size, battery capacity & run-time, expandable storage. I can deal with the size, I'm a Note fan (Also have the 5.9" Pantech Vega N°6, which is a mammoth device). Although flip cases are not my bag, a portable kickstand with 20% extra battery sounds fantastic. The metal build, the stereo speakers, the SLCD when I'm getting awfully sick of poorly calibrated AMOLED panels, it all stacks up. They're even taking proper advantage of the screen size with a 5x5 home screen grid, Samsung's persistence with 4x4 on the Note II & 3 is baffling to me. The lack of OIS is a downer, I do love and use the S Pen regularly, the lack of S800 is almost deal-breaking, and yet...

    HTC have finally made a device that appeals to the core of my smartphone experience, and I feel compelled to give them money in the hopes they keep doing this.

    @Davidjan

    Thanks for the tip on the Meenova OTG-SD card adapter! I just went and bought one, even though I don't yet have an Android device. I will someday, and this is too good to pass up. Plus, such a tiny company could disappear. BTW I lobbied Sandisk, Transcend etc a year ago for something like this but those that replied said it couldn't be done...

    As for Brian Klug's comment that microSD is "going the way of the dodo": He probably thinks that means an evolutionary death. In fact the dodo was killed off by idiots with no concern for the future. There's nothing "natural" about losing microSD - it packs huge amounts of affordable storage in a tiny, rugged, hot-swap package. It should rightfully be with us for many years. Unfortunately, it's being marketed out existence by tablet makers pushing internal RAM, telecom carriers pushing data usage, and probably even Hollywood.
