The Sony Xperia E4 is equipped with a pretty plain IPS LCD panel with a resolution of 540 x 960 pixels on a 5-inch diagonal. The resulting 220ppi is nothing special but probably just right for the price range.
It's not the resolution though that we're worried about. The thing that really ruins the experience is the plastic screen coating, which is very reflective.
While taking the microscopic photo, we had a very hard time focusing to get all three colors right. The distortion is most probably the reason why the display appears constantly blurry.
Screen colors are otherwise good enough but the reflective coating ruins the experience as a whole.
The only bright side to it (pun intended) are the side viewing angles, which are quite ok despite the bad front glass.
The display did quite poorly in our brightness and contrast tests. It scored surprisingly low in both and was even surpassed by its predecessor - the Xperia E3.

Using the phone outdoors under direct sunlight is by no means comfortable.

Battery
Sony has put a 2,300mAh battery inside the Xperia E4. We ran our battery test with the battery-saving STAMINA mode off. The handset scored a solid 88 hours, which means you can count on about 3 and a half days if you do an hour each of calls, web browsing and video playback a day.
The battery is not user-removable, even though the general design of the phone suggests otherwise.
The Power Saver - now part of the settings menu - helps you extend your battery life by toggling things like Wi-Fi, GPS, Bluetooth screen brightness, auto sync and background data on and off automatically, as soon as the battery charge falls below a certain user-defined threshold. You can also choose to automatically turn Wi-Fi off if there is no known Wi-Fi network in range or switch off mobile data when the screen is off, and more.
Our proprietary score also includes a standby battery draw test, which is not featured in our battery test scorecard but is calculated in the total endurance rating.
The Sony Xperia E4 comes in single and dual SIM flavors. Both models offer quad-band GSM/GPRS/EDGE support and dual or tri-band 3G connectivity with HSDPA. LTE support is only available on the Xperia E4g, which is a different phone altogether.
Local connectivity features single-band Wi-Fi b/g/n and Wi-Fi Direct. There is also support for Bluetooth 4.1 with A2DP and apt-X. Satellite navigation is limited to GPS with no GLONASS support. The Xperia E4 also has an FM radio with RDS. It doesn't offer NFC or an IR port.
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.
The microUSB port doesn't have any TV-out functionality, 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.
