the buttons. The thin bezels of the G3, along with its curved shape, are intended to help improve grip and make the device feel smaller than it actually is, given its screen size. Battery optimizations While the G3's battery has the same capacity as the G2, a subtly-curved "arc battery" had to be designed so it could fit under the G3's curved rear cover. To achieve battery life comparable to other "1080p flagship" devices—especially given the significantly higher resolution of its screen, several optimization measures are implemented in the G3's software. These include capping the frame rate rendered when the screen is displaying static content, and underclocking the processor when the device is not running processor-intensive applications. With these optimizations, LG demonstrated that the G3 could play video for six and a half hours at full screen brightness on a single charge. Laser auto focus The G3 incorporates a "laser autofocus" system, being among the first smartphones to incorporate such a feature. Based on technology that was being researched for the LG Roboking robotic vacuum cleaner line, but ultimately left unused, the system uses a cone-shaped infrared beam to map the depth and position of objects; this data can be combined with traditional autofocus mechanisms, and face detection capabilities. LG claimed that this system gave the G3 the fastest autofocus time of any smartphone, 276 milliseconds. Other recent phones, such as the HTC One (M8) and Samsung Galaxy S5, had boasted autofocus times of 300 milliseconds. The introduction of the laser into the G3's feature set occurred late in development, and the majority of the mockups were not designed to compensate for its presence, requiring additional tweaks to the phone's shape. Specifications Hardware Exterior The G3's exterior incorporates a scratch-resistant "metallic skin"—consisting of polycarbonate finished to look and feel like brushed metal; despite being branded as "metallic", the G3's exterior does not use actual metal. The finishing is intended primarily to improve grip, and to make the rear casing less susceptible to fingerprint smudging. The G3 is available in black, white, gold, burgundy, and violet color finishes. Design elements from the G2 are retained by the G3, such as its rear-mounted volume and power buttons. In comparison to the G2, the buttons were given a flatter design with a new, rounded shape. Display The G3 features a , 1440p quad HD IPS LCD display—the first major "global" smartphone to use
