HTC has officially introduced its One X+ mobile phone, building on the One X handset.
Its predecessor is one of the most popular smartphones in the UK and the upgrade sees hardware and software improvements.
As a leaked document allegedly from the telecommunications network O2 said, the gadget will come with 64 GB of internal storage and a 1.7 GHz quad-core processor.
The battery gets an upgrade from 1,800 mAh to 2,100 mAh, meaning the additional power required by the faster processor will not drain life too quickly.
The Google Android operating system is promoted from Ice Cream Sandwich to Jelly Bean and HTC has confirmed One X and One S handset owners will be able to upgrade soon.
Despite this being the latest version, only 1.8 per cent of Android users are currently using the software.
Most people (55.8 per cent) are still using Gingerbread, which is now three versions old.
The device should be in UK stores in October and if the leak was accurate, O2 will have the phone available on pay-and-go for £479.
