HTC has upgraded its flagship smartphone, the One X, with a quad-core processor, twice the integrated storage capacity and a bigger battery.
The new model is called the HTC One X+, and the company will be hoping that it can compete more successfully than its predecessor with Samsung's Galaxy S III and Apple's iPhone. Just like other vendors HTC has had a hard time keeping up with the smartphone market's two dominating forces.
The One X+ is powered by a 1.7GHz quad-core Nvidia Tegra 3 AP37 processor and has 64GB of integrated storage.
The processor upgrade will improve the overall performance of the phone, including smoother gaming and faster downloads, according to HTC. The original 3G model had a 1.5GHz quad-core processor.
HTC has also increased the size of the battery from 1,800mAh to 2,100mAh.
The screen still measures 4.7 inches and has the same 1280-by-720-pixel resolution, but it is now protected by Gorilla Glass 2. The phone's size is also the same, but it is 5g heavier.
The phone now announced is 3G only, according to HTC's spec sheet.
In the US, LTE has become a standard feature on smartphones from Verizon Wireless and AT&T. But LTE has also started to take off in Europe; the Samsung Galaxy S III and the iPhone 5 both support LTE spectrum bands used in countries such as the UK and Germany.
HTC didn't immediately reply to questions about a One X+ with LTE for Europe.
On the software side, the One X+ will use Android 4.1 Jelly Bean, which will also be available for the One X and the One S from October.
The new phone will start shipping this month in Europe and Asia, but pricing was not announced.
