We bring this up because of a leaked version of Sense 4.1 for the international version of the HTC One X that made its way in ROM form to XDA Developers. Instead of trying to be too clever for its own good with Sense 4.0, HTC had worked on making things faster. This carried over to Sense 4.1 and the HTC One X with the leaked ROM scored close to 6000 on the Quadrant Benchmark test.
2.15.401.5, included some fixes including the removal of lags on Live Wallpaper, a dedicated button added in the camera app to switch between front and back camera (no more having to go into the menu), a dedicated button added to the browser to switch tabs (again, no more trips to the menu) and all 3-D effects were removed from the launcher to remove the lag. With the ROM comes Android 4.0.4.
Other changes include a new kernel described as being "blazing fast" which is obvious considering the improvement in the Quadrant score, the ability to remap the recent apps button switching between recent apps and Home as Menu, a fix of weak Wi-Fi signals, and most importantly, the ROM brings a longer battery life of 5+ hours of screen-on time compared to 3+ hours on Sense 4.0.
