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.

    "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.
