Sony Xperia Z Review

Sony Xperia Z
The Sony Xperia Z was officially launched in early 2013 around January. The phone is the first 4G/LTE smartphone created by Sony.

Design & Build

The Xperia Z is noted to be a water and dust resistant device. It is designed as a super slim cell phone that has a width of 7.9 mm, rounded edges, and a smooth mirror-like surface on both sides. The front surface display is made of Dragontrail and the backside surface is made of Corning Gorilla Glass, which is known for its lightness, thinness, hardness and damage-resistance. The glass is resistant to cracks and shatter-proof which makes it more durable compared to other smartphones in the market today. The Xperia Z has a 5″ HD (High Definition) display that shows images in vivid colors and clear details. The image resolution is 1080P and there are no jagged edges visible within the picture. Also, the Sony Xperia Z has 3 colors to choose from: black, purple, and white.

The only buttons that can be seen on the smartphone is the volume and power button at the right side of the device. The opposite side has a micro-SIM card slot, SD card slot, USB port and jack port. Each port has its respective covers to prevent water and dust. The Xperia Z has a micro SIM card and microSD card, which is upgradable to 64 GB. The cell phone’s internal memory is 16 GB and has 2GB of RAM.


The Sony Xperia Z has 2 cameras: a front and rear camera. Its primary camera on the backside is 13.1 MP that includes an LED flash and auto focus. The front camera resolution is 2.2 MP. The camera app features geo-tagging, image stabilization, touch focus, sweep panorama, and face detection. With low contrast shots, one can turn on its HDR (High Dynamic Range) or high contrast setting to provide a clear image. When it comes to night shots, it uses an Exmor R image sensor so even if the subject is backlit it will capture clear photos and videos.


The operating system (OS) is Android OS v4.1.2 (Jelly Bean), which is upgradable to OS v4.2.2 through an OTA (over-the-air) update. The chipset, which is known as the “brain” of the Sony Xperia Z, is a Qualcomm Snapdragon S4 Pro and the CPU (central processing unit) is a quad-core 1.5 GHz Krait that can perform multiple tasks. Users will be able to switch from one application to another without lagging and can smoothly swipe between screens.


The battery on the Xperia Z is non-removable and the battery life is usually a concern of most users. If the phone is on standby mode with 2G coverage, it will last 550 hours. On 3G, the phone will last 530 hours on standby. For talk time, the cell phone will last 14 hours on 2G and will last 11 hours on 3G. If you will play music, the battery is good for 40 hours. According to Sony, the Xperia Z has a 48 hour endurance rating. The battery icon has color coding to signify battery life. If the icon is red, the battery life is below 50%; orange – 50% to 70%; and green – 70% to 100%.


For connectivity, the Sony Xperia Z is able to connect with GPRS, Edge, 2G, 3G, 4G and LTE (based on carrier coverage and location of the user). For data connection, it can connect to GPRS up to 107 Kbps, Edge at 296 Kbps,  HSDPA at 42 Mbps, HSUPA at 58 Mbps, or LTE at 100 Mbps. Also, the phone can connect through WLAN such as: Wi-Fi, Wi-Fi Direct, Wi-Fi hotspot or tethering, commonly known as internet sharing. Additional connection options include bluetooth, microUSB, and NFC (near field communication).

Pre-Installed Apps & Accessories

The phone apps include Walkmann, movies, messaging (SMS & MMS), IM, push email (transferring email directly to the mobile phone), browser (HTML 5 or Launch Pro), GPS (A-GPS support and GLONASS), personal content station (wireless hub for videos and pictures), radio, and more. Included in the box are a charger, USB cable, headset, and cell phone manual.


The Sony Xperia Z is advisable for people who love outdoors due to its water and dust resistance. The cell phone can be submerged in water no more than 4 feet (1 meter) and not longer than 30 minutes. The phone can synchronize and view photos or videos directly on your Sony Bravia TV or other devices by one-touch mirroring. OTA updates availability is somewhat delayed compared to updates from the Google Play store. Fortunately, the Android OS v4.2.2 Jelly Bean is now available to update the phone’s stock OS version. Phone owners can install the app “CPU master” which may help in increasing the battery life of the Sony Xperia Z. For gaming, Temple Run and Candy Crush Saga run smoothly with great visuals and graphics. By watching movies and playing games, the device may become hot and that is usually the most common complaint among my friends. For sound, using the headset provides a better experience since Sony specializes in audio. Overall, I give 4 out of 5 stars for the Sony Xperia Z. With Sony’s phone design and performance, the Xperia Z is hard to beat when it comes to smartphones.
