Sony's new Xperia series flagship, Xperia Z2, integrates better camera and camecorder technology, a larger display and a more powerful quad-core processor than its predecessor. Besides, the new Xperia has a 3,200mAh battery inside, which stores 200mAh more power than the Xperia Z1.
Although the 200mAh extra energy does not sound much, battery tests suggest otherwise. GSMArena has conducted a series of battery tests according to which the Xperia Z2 outscored the Xperia Z1 as well as its primary rival smartphones such as Samsung Galaxy S5 and HTC One M8.
The Xperia Z2 managed to deliver an impressive talk time of up to 22 hours three minutes in the battery test, securing the 20<sup>th position in the list.
The Galaxy S5 was one hour behind with a talk time of up to 21: 20 hours whereas the HTC One M8 was two hours behind the Xperia Z2, offering a talk time of up to 20:01 hours.
Its predecessor, the Xperia Z1, performed better offering more than four hours of talk time. The Galaxy Tab Pro 10.1 LTE occupied the first place in the list with the longest talk time of up to 46:44 hours.
The Xperia Z2 also performed well in the web browsing battery test and was among the top performers. The handset lasted for 11:32 hours, almost twice longer than the internet use by the Xperia Z1, at 5:59 hours.
The Xperia Z2 was once again ahead of both the Galaxy S5 and HTC One M8, with both the devices lasting for more than nine hours. Sony's Xperia C delivered the longest internet use of up to 12:45 hours.
In the video playback test, the Xperia Z2's battery drained out after 12:16 hours, one hour longer than the video playback time offered by the Galaxy S5 and HTC One M8.
The Xperia Z1, in the same test, stayed for 6:12 hours, half the video playback time of its successor. But the Xperia Z2 failed to beat the LG G flex, which was the winner in the video playback battery test (19:57 hours).
The Xperia Z2 scored an endurance rating of 89 hours, which means the new Xperia smartphone can run for 89 hours with one hour each for calling, video, and browsing.
