Lenovo Vibe X2 review: Rainbow of colors

Display

The Lenovo Vibe X2 is built around a 5" IPS LCD display with a 1920 x 1080 pixel resolution. This results in a respectable pixel density of 441ppi.

The display is great

The display is covered with a protective layer of Gorilla Glass 3 making it resistant to minor scratches. A cool feature is the smart brightness option, which detects any hard lights hitting the display and adjusts the brightness automatically.

The matrix is a standard RGB type with an equally sized red, green and blue pixels. Here's the display matrix of the Lenovo Vibe X2 Pro shot with our digital microscope.

We are happy with the colors that the Vibe X2's display outputs. Its IPS display offers an adequate brightness at both 50% and 100% and more than okay contrast. Viewing angles are also fine with minor shift in contrast and color. You also won't have troubles viewing the display in a sunny weather.

Battery life test

The Lenovo Vibe X2 sports a 2,300mAh battery. It may not offer game changing battery life, but it's still a commendable battery capacity from a phone with a 7.3mm waistline. Still, that's no excuse for Lenovo for not fitting a larger battery, considering its direct competitor, Huawei, has fitted the similarly sized Honor 6 with a 3,100mAh battery.

With this little rant aside, the phone did okay in our usual battery tests consisting of talk time, video playback, web browsing and stand-by. The phone managed an overall endurance rating of 50 hours, which is adequate, but not impressive.

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.

Our battery testing procedure is described in detail in case you want to learn more about it.

In regards to power management, it's worth noting that the company has baked in a handy power manager app. It gives you a clear reading of what battery power you have left and an estimation of how much battery life it would provide.

There are also three power profiles you can pick from: normal, power saving and emergency. Power saving mode will block apps running in the background and also downclock the CPU a bit to make the phone more energy-efficient, while still retaining most of its functionality.

Freezing apps from drawing power

Emergency mode goes a bit extreme by limiting functionality only to calling and messaging. Anything else on the phone is disabled, allowing it to spread that remaining charge over several hours or even days.

Another cool feature of the Power manager app is the Power saving engine, which optimizes the phone's brightness by something they call "sine wave power-saving technology". Lenovo estimates it can reduce power consumption by 5-30%. There's a similar option for the GPU and its potential power reduction goes as far as 25%. If you want to get even more juice out of the battery, the app allows you to schedule a timed shut down of the phone.

The Vibe X2 allows you to freeze apps or see a detailed graph of the power consumption. The latter is separated into software and hardware. The software part is akin to the stock Android battery graph, while the hardware shows you how much power the CPU, screen, radio, Wi-Fi and other hardware components draw out.

Turning the phone automatically on and off is a cool feat

Finally, there's the option to optimize power consumption. The button is located at the bottom and upon pressing it, the app detects what draws the most power and offers you advice on how to go about it. It's clear that Lenovo has turned special attention to getting the most out of the Vibe X2 battery.

Connectivity

The Lenovo Vibe X2 comes with truly global quad-band 2G/GPRS/EDGE and penta-band 3G with HSPA (up to 42Mbps downlink and 5.7Mbps uplink) cellular connectivity. The six-band Cat. 4 LTE support (up to 150Mbps download, and up to 50Mbps uploads) is not the best around, but it still covers plenty of big names in the 4G business.

The phone is available in single SIM and Dual SIM configuration. The latter has a dedicated SIM management section in its settings menu and is only available in India for now. It allows you to choose which SIM card is active and the default SIM to use for placing voice calls, data connectivity or messages.

Local connectivity is covered by dual-band Wi-Fi a/b/g/n/ac with DLNA, so you can easily play media (photos, videos, music) from DLNA-enabled storage devices or push content from your phone to a DLNA-compatible TV or music player.

Bluetooth 4.0 is also on board with A2DP, EDR, and LE. GPS and GLONASS support is enabled. There's an FM radio, but no NFC or Infrared on board.
