For a while now there has been chatter about HTC updating its One X line, and today those plans have become official with the HTC One X+. The update is a significant spec bump from the existing Tegra 3 based One X, and includes a faster version of Nvidia's Tegra 3 SoC (AP37 in the place of AP33), up to 64GB of NAND, an improved 1.6MP front facing camera, Android 4.1 Jelly Bean with Sense 4+, and a larger 2100 mAh battery. But one of the most important and interesting parts is that the One X+ includes support for LTE without using a Snapdragon S4 SoC, instead HTC will ship a One X+ with LTE support courtesy Qualcomm's MDM9215 baseband, and a version with the same GSM/WCDMA support as the existing One X through another Intel XMM6260 baseband. 

The move from Tegra 3 AP33 in the international One X to AP37 affords a jump in maximum single-core CPU clock from 1.5 GHz to 1.7 GHz, and a jump in the GeForce ULP GPU clock from 416 MHz to 520 MHz. Otherwise this is the same 40nm LPG Tegra 3 with four ARM Cortex A9s and a fifth 'shadow core' A9 for hotplugging in idle states. HTC reports an increase in performance of 27 percent over the previous One X (T3) and 37 percent more talk time battery life.   

I've put together a comparison table with the details of the One X+ in comparison to the previous One X (T3) and One X (MSM8960) version also known as the One XL. The One XL doesn't go away now that the One X+ is out, either, but the One X+ with LTE does take its place at the high end.

The One X+ also ships running Android 4.1 Jelly Bean and HTC Sense 4+ which includes improvements to Sense UI and layout. I had a chance to play with the One X+ running Android 4.1 and noted some welcome improvements to the stock HTC keyboard, and that Sense 4+ struck a good balance with the changes made in Android 4.1's UI, including the better notifications and different styling. Both the existing international One X and One S will be updated to Android 4.1 sometime in October.

The One X+ is slightly heavier in the hands (135 vs 130 grams) but doesn't feel all that different and maintains the same external dimensions. I wasn't able to determine if the larger battery includes the higher voltage chemistry that a number of other OEMs have moved to, though it's obvious the energy density has gone up. 

The non-LTE One X+ includes the same GSM/EDGE and WCDMA bands as the previous international version (850/900/1900/2100 MHz for WCDMA, 850/900/1800/1900 MHz for GSM/EDGE) and of course the same HSPA+ capabilities since it includes the same Intel XMM6260 baseband. I don't have any word at the moment on what LTE bands will be supported on the One X+ with LTE, but with MDM9215 and possibly WTR1605 we could see more than the One XL. Qualcomm's MSM8960 SoC contains the same IP block that's inside MDM9215 and is still 28nm. It's interesting to see the One X+ using this combination as it may finally put to rest the talk of Tegra 3 being "incompatible" with LTE.

    compared to other new phones.....better if Note II is included...
  • Paulman - Tuesday, October 2, 2012 - link

    I'm planning on getting the Galaxy Note II, though it looks like the HTC One X+ has a few points of similarity with it (e.g. similarly clocked, quad-A9 cores, LTE support).

    I was always tempted by the HTC One X's IPS LCD screen (since I don't like AMOLED's unevenness/inconsistency and battery draw), but I've heard and maybe even observed first hand that the SenseUI implementation is noticeably laggier than stock Android and even TouchWiz. Also, the SenseUI has always been praised as better looking that TouchWiz, but I always found it to be a little bit oversized for my liking.

    Are any of these points about SenseUI true? And has Sense 4+ changed this?

    Another thing I've always wondered about: are the LTE basebands used in the Galaxy Note II and HTC One X+ made on the 28nm process (like the iPhone 5's LTE)? I think the LTE baseband for the Exynos 4412 is off-chip, but should I expect that it's also manufactured on Samsung's 32nm HKMG process? In any case, should we expect it to be much better than previous gen LTE's (e.g. S II LTE, aka AT&T Skyrocket) and similar in power draw to the iPhone 5's LTE baseband? (Whew, those were a lot of questions)

    The One X+ with 4.1 felt considerably smoother than I'm used to on my One X (8960), not sure how much of that is just 4.1 versus Sense 4 being brought under control. I've always felt that the T3 One X with Sense 4 was slower at redrawing certain elements for some reason.

    MDM9x15 is 28nm and inside iPhone 5, One X+, etc.
    MDM9x00 is 45nm and inside SGS2 LTE / Skyrocket, etc

    glad they're improving on the LTE chips.

    I wonder why these OEM and/or OS are not providing toggle buttons to easily support changes between 2g/3g/4g speeds. I know a lot of people are preferring 4g/LTE speed. But I'm on 2g most of the time, it saves tons of battery and it's sufficient enough for me to text with whatsapp and email. I do not watch youtube or netflix o the go.

    The Samsung Galaxy SII HD LTE (i757) from Bell (similar to the Skyrocket on AT&T) includes a separate toggle buttons for LTE, 4G/HSPA, and 3G. It's on the same page as the wireless toggle.

    Very handy, as we don't have LTE in our city as yet (scheduled for sometime in 2013), so there's no point in running the radio at all.

    My HTC EVO 4G LTE lets you easily switch from CDMA/LTE to CDMA only...
  • neothe0ne - Tuesday, October 2, 2012 - link

    The 16 GB of storage was crippling for the US market but if this comes over in 32 and 64, it would probably be the best phone on the market. Screen should still be #1 and in practice, the camera (software) should (still) beat the Galaxy S III.

    Any word on release date in US, Europe, or anywhere else? (I realize we still don't even know the LTE bands...)
  • bill4 - Tuesday, October 2, 2012 - link

    Disagree. The GS3 has a bigger screen, 2GB RAM, and from what I've seen I prefer Touchwiz to Sense.

    Plus the One-X has some weird crippled multitasking going on I understand.

    Screens are a matter of taste imo, the true blacks of SAMOLED are pretty nice. Whatever the case, my GS3 screen is absolutely gorgeous and the whole pentile thing is overblown.

    Also HTC seems to have quality control problems compared to Samsung. I also just read a youtube comment that Tegra 3 is junk and that the audio DAC in Tegra 3 is crap too (I wouldn't know anything about this personally LOL)

    I bet performance isn't better, if not worse, than Krait as well.

    Plus you get removable SD slot, battery.

    anyways, super happy GS3 owner here.

    You read a YouTube comment? Holy cow, A+ source right there.

    Hahaha, +1 to that
