The Z5 Premium has a 23MP camera on the back, which can take highly detailed but slightly dull shots, while there’s a fairly standard 5.1MP snapper on the front. We say likely because we haven’t had a chance to comprehensively test them yet, but early impressions are positive, and the Xperia Z5 Premium’s snappers are far from the best around. The Sony Xperia XZ Premium likely has better cameras on both the front and back. The Xperia XZ Premium also has a newer, more powerful, and more efficient Snapdragon 835 chipset powering it, in place of the Snapdragon 810 in the Xperia Z5 Premium, so hopefully every mAh of its battery will go further. Both phones support fast charging, but the XZ Premium adds clever Qnovo adaptive charging to the mix, which should ensure the battery doesn’t wear out as fast. The XZ Premium does have a few things in its favor though.

We’ll have to put it through a full review before we can say for sure which phone wins out here, but it’s very possible that they’ll both be losers. That’s a worry, because it’s likely the 4K screen that’s to blame, yet the equally sharp Xperia XZ Premium actually has a smaller 3,230mAh battery. The Sony Xperia Z5 Premium doesn’t have great battery life, regularly needing a charge before bed time, and that’s despite having a fairly large 3,430mAh juice pack.

Stick a 4K HDR video on during your commute and you’re sure to attract the envious gaze of other passengers, as that combination is something no other phone can display. Where the XZ Premium really has the edge is in that it also supports HDR content.
