Battery test: no champs
Like we've seen previously on Android phones, the Qualcomm Snapdragon S4 is a fast processor that also uses a lot of power. This can be seen in the worst-case benchmark where we continuously run the Sunspider benchmark while also playing music. The Lumia 920 last a little longer than three hours, and the HTC 8X lasts a little less than three hours. While the battery inside the Lumia 920 has 10 percent more capacity the difference is minor, which is liekly due to the larger screen of the Lumia 920. With normal use both phones aren't super-efficient either, after a day of average use both will have to be charged.
