Just six months after HTC released its flagship One X smartphone, the company is at it again. The followup, dubbed the One X+, comes with many of same features as its predecessor but with a few small upgrades.

HTC has updated the processor to a quad-core Tegra 3, for example, and boosted the on-board storage to 64GB. Android Jelly Bean is here, as is the latest version of HTC’s Sense user interface.

HTC also upgraded the battery to 2,100 up from 1,800 mAh (though it still pales in comparison to, say, the 3,300 mAh of the Droid Maxx HD).

One big question is whether the One X+ will be joined by an updated version of the EVO 4G LTE, which was Sprint’s own version of the phone. Same goes for the One S, which belongs to T-Mobile.

Europe and North Asia will get the One X+ this month, and South Asia will get it in November. North Americans — you’ll just have to wait for that information from carriers.

Release date questions aside, we do know that the One X+ is going to enter into a holiday smartphone market packed with powerful flagship devices. We’ve already reported on how that could be a problem for LG’s Optimus G, and chances are that HTC could have similar problems with its One X upgrade.
