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.

    If you're going to leave out the microSD slot, at least give the device 64GB minimum. They've done that, and so I think this is a pretty nice device now.

    Will Sprint be updating their version of this phone?
  • Impulses - Tuesday, October 2, 2012 - link

    Sprint's EVO 4G LTE already had a larger battery (same as the One X+), not to mention 16GB PLUS a microSD slot with which you can easily add 32GB or even 64GB for $20-50... I think it'd be pointless for them to update it. They just need to get the Jelly Bean update out.

    Your article mentions a 27% jump in performance whereas the website you linked to mentions 67%. Please confirm which one is correct.

    What are the differences between MDM9215 and MDM9615?
    What could be the reasons for HTC to use MDM9215 in X+ when Apple is using MDM9615 in iPhone 5?
  • newbietech - Tuesday, October 2, 2012 - link

    MDM9215 seems to have most of MDM9615 except for EVDO.

    As far as I understand from just observing Qualcomm and it's products, it's only CDMA support that differs here. It's not a CDMA-phone so. From the product table it's also suppose to support Rel 9 DC-HSPA+ though, but I don't get why it should be any different there, though that would be DC-HSDPA plus MIMO. Which I guess most products wouldn't support. CDMA is the normal difference between x6xx and x2xx variants any way. CDMA and price is the only real thing I can think of. MDM9625 would have been interesting if it were around already. Those might support with WRT1605 up to 7 LTE-bands too.

    if i buy this model from USA and use in India, does the LTE work here in india or only 3 will work?
  • Peanutsrevenge - Wednesday, October 3, 2012 - link

    You'll need to wait and see what bands this phone supports and check if your carrier uses the same bands.

    If your carrier is using bands not supported by the phone, then no, it won't work.
    If they match, you're a good'un.

    Do we have LTE in India?
    Only provider for LTE in India is Airtel. However, they are not advertising as an Voice + Data service. And from what I could glean, it is restricted to their 4G USB Modems.
