Sony Xperia C4 Dual review: Flashy performer
Sharp 5.5-inch FullHD Display
Aside from the 5MP front camera with flash, the Xperia C4 is interesting in no small part because of its display. As it stands now it's the best specced phone Sony has to offer with a diagonal larger than 5.2 inches. One might argue that the Xperia Z Ultra may still hold that title, but at 6.4 inches it's clearly pushing the boundaries of what you can call a phone, even if the Snapdragon 800 could still pull its own weight.
Anyway, the Sony Xperia C4 comes with a 5.5-inch display with 1,080 x 1,920 pixels resolution and that's good for 401ppi density. It's got nice colors, though a bit subdued at the default setting, and the Super-vivid mode doesn't do all that much in terms of punch. You do get the option to tweak the white balance with RGB sliders but there are no presets.
Side viewing is a non-issue, and the inevitable contrast compression and minor drop in brightness don't get in the way of sharing the content on that fine display.
There aren't many options you can fiddle with on the display, but there is a glove mode.
Our microscope shot revealed the expected standard arrangement with equal numbers of red, green and blue pixels.
Our lab tests also revealed the Xperia C4's display to be plenty bright at the maximum setting, so much so that despite the averagely lit blacks, contrast is still high. What's nice to see for a change is the nearly linear slider for brightness adjustment, with the 50% percent setting equating to about 54% of actual maximum.

Not one to excel at sunlight legibility, the LCD tech inside the C4 still managed a decent score in our test.

Connectivity
The Sony Xperia C4 comes in single and dual SIM flavors. Both the versions offer quad-band GSM/GPRS/EDGE/HSDPA support. Cat.4 LTE support is also present, though only one of the SIM is graced with it in the C4 Dual model.
Local connectivity features dial-band Wi-Fi a/b/g/n with Wi-Fi Direct and hotspot. There is also support for Bluetooth 4.1 with A2DP. Satellite navigation is also a given, with additional A-GPS and GLONASS support. The Xperia C4 also has an FM radio with RDS. It doesn't offer an IR port, but it does come with NFC.
There is a microUSB 2.0 port for charging and data connections. Media transfer mode is supported for accessing the phone's built-in memory and microSD card over the USB cable. USB OTG functionality is also present and it works fine should you decide to chain-link a mouse and a flash drive in a keyboard and connect the lot, if that's your thing.
The microUSB port doesn't have any TV-out functionality though, but if you own a compatible HDTV, you can output your phone's screen wirelessly via the Miracast protocol or Sony's Xperia Connectivity Throw option.
The app also lets you share your media over DLNA by creating a media server, as well as connect to a PlayStation DUALSHOCK 3 (or 4) wireless controller.
Battery life test
The Sony Xperia C4 comes with a 2,600mAh battery, which makes it a bit underpowered for a 5.5-inch FullHD device. That said, the Samsung Galaxy A7 did very well with its equal capacity, and so did the Vivo X5Max we reviewed only a couple of weeks ago with only 2,300mAh.
The harsh reality is, however, that the Xperia C4 is struggling to remain lit up for more than 7 hours. The web browsing test depletes the battery in a little over that, while the video playback longevity can't even make it to the 6-hour mark. However, you should have in mind that the smartphone's brightness at the typical 50% setting we carry out those tests at, is around 350 nits, which is nearly twice as high as some competitors.
The 3G talk time is only average, so the Xperia C4 can't redeem itself on that front, and it only leaves the efficient standby in its favor.
The battery testing procedure is described in detail in case you're interested in the nitty-gritties.
