Sony Xperia XZ4 could squeeze crazy big battery into impressively thin body
Leaked CAD-based Sony Xperia XZ4 renders
Widely expected to be formally unveiled at next month’s Mobile World Congress in Barcelona, the extra-tall flagship smartphone was purportedly rendered a couple of months back, with a number of its key specifications rumored shortly thereafter.
We want to believe
Purported Xperia XZ4 specs, part 1
That would be significantly larger than the 3,300 and 3,540 mAh cells found under the hood of the Xperia XZ3 and XZ2 Premium respectively. Granted, the two 2018-released high-enders also come with smaller 6-inch and 5.8-inch displays.
Speaking of that, the Xperia XZ4 looks set to be only the company’s second-ever OLED phone, after the XZ3. The 18:9 aspect ratio will most likely be expanded to 21:9 for a (hopefully) more immersive video content playing experience, while the resolution is expected to go up from 2880 x 1440 to 3360 x 1440 pixels.
That sounds impressive, but it would actually be down from the 3840 x 2160 pixel count of the Xperia XZ2 Premium’s LCD panel. Of course, pixels become irrelevant beyond a certain number, as proven by the iPhone XS and XR, among many others.
The sketchy parts
Remember the Xperia XZ2 Premium and Xperia XZ3? Both of those are heavier and thicker than an XZ4 that’s supposed to come with a bigger screen and bigger battery. Even the Samsung Galaxy Note 9, which is an absolute engineering marvel, “only” manages to squeeze a 4,000 mAh cell into a chassis measuring 8.8 mm in depth and tipping the scales at 201 grams.

If Sony is indeed able to pull off that battery capacity with those measurements, the Xperia XZ4 will surely be a heavyweight contender for the title of best H1 2019 flagship phone. But realistically speaking, the previously rumored 3,900 mAh battery size still feels more plausible. Either that or the device will be significantly thicker and heavier than currently expected.
Assuming the rest of the info is legit, the XZ4 should measure 167 mm in height and 72 mm in width, while packing 6GB RAM and 128GB internal storage space (at least in this specific configuration). For comparison, the Xperia XZ3 is 158 mm tall, 73 mm wide, and exclusively available in Taiwan in a 6 gig memory variant that still offers just 64GB local digital hoarding room.
