Sony Xperia Z4 specs leak, suggest modest improvements

After recently testing out a Sony Xperia Z3v smartphone and walking away impressed, I wondered what the company would do with its next flagship.

It looks like it may not change much, and that could be a good thing. Even better for those who don’t want 6-inch or larger phones, the Sony Xperia Z4 display will only grow 0.2-inches over the prior model, based on leaked specifications tipped to Phone Arena.

Obviously, we won’t know if these are the real deal until [company]Sony[/company]’s CES press event on January 5. However, the specs make sense to me because they would improve the older model in all the right places.

Sony’s Triluminos display for the Z4 is expected to measure 5.4-inches diagonally with Quad HD, or 2560 x 1440 resolution. That works out to a pixel density of 544 pixels per inch: sharp and large, but not overly big. Sony is pretty good about phone design, keeping the bezels quite small, which would also help keep the size down.

The Xperia Z3 lineup launched with [company]Qualcomm[/company]’s Snapdragon 801 earlier this year, mainly because the newer 805 wasn’t yet available. The tipped specs indicate the Z4 will get the 805 processor, along with 4 GB of memory; a boost over the 3 GB in the current model. That would be a potent combination for [company]Google[/company] Android 5.0. Might Sony use the new Snapdragon 808 or 810 chip?

It depends on when the phone actually launches, because products using those chips — the first 64-bit silicon from Qualcomm — aren’t expected until sometime in the first half of 2015. If Sony is content to wait on phone availability until the second quarter of next year, it might be possible to use the next round of chips.

The tipster also told Phone Arena that Sony would keep the 20.7 megapixel rear camera found on the Z3 but plans to use a newer Sony image sensor. The front facing camera may get a nice boost to 4.8 megapixels with a wide viewing angle — something I really came to appreciate on the HTC One M8 for group selfies.

I found battery life on the Sony Xperia Z3v to be excellent but it may be even better if on the Z4 if the expected 3420 mAh battery is included. Sony’s last flagship could eke out two days of run time on a charge with its 3200 mAh battery and I’d expect at least the same from a new model if these are indeed accurate specifications.
