A new HTC device spotted in the AnTuTu benchmark database could be the successor of the 2013 Butterfly s.

Bearing the 0PAJ3 code number, this previously unknown smartphone shares many of the core specifications with the freshly launched HTC One M8, with one big difference. The benchmark entry suggests the device will be equipped with a 13MP camera, instead of the 4 UltraPixels unit on the M8, as well as the original One from last year.

HTC is due to refresh the Butterfly series this summer; the previous iteration, the Butterfly s, debuted in July 2013. While it’s possible that this benchmark entry refers to something else, there’s a relatively good chance we just had a look at the new Butterfly.

The Butterfly s had a 4 UltraPixels camera, so, if our assumption is correct, HTC will go back to a conventional sensor for the new generation, possibly to cut costs.

Other specs revealed are a Qualcomm Snapdragon 801 processor capped at 2.3GHz with an Adreno 330 GPU and 2GB of RAM. While the new Snapdragon 805 will be available by mid-year, we think HTC will stick with the 801 for the new Butterfly.

The display will retain the Full HD resolution, though HTC might increase its size (the Butterfly s had a 5-inch SLCD3 screen). The front camera is a 5MP unit, presumably coupled with a wide field lens, just like the one on the M8. Finally, there’s Android 4.4.2 listed as the OS, which is really no surprise.

The Butterfly s had a large 3200 mAh battery, which was quite impressive for a 5-inch device. There’s no mention of battery capacity in the benchmark, but hopefully the new Butterfly won’t disappoint.

HTC sold the Butterfly s mostly in Asian markets, though the original 2012 Butterfly made it to Europe and to the US (sold as Droid DNA).
