Battery Life over Thickness of Phone

The article talks about the topic Battery life over thickness of phone

The latest generation of phones, 5 inches wide are power hungry and battery backup is the major cause of concern now. No more is the thinness of the device a fancy among vendors and they are looking out for bigger batteries.

The ‘thin’ market now has an HTC full HD, 5-inch Butterfly on its Droid DNA phone, LG expanded its range by introducing a G Pro in its Optimus range, Sony and Huawei Technologies are nowhere behind.

The Optimus G Pro is quite a looker with a 5-inch screen with resolution of 1920 by 1080 pixels and Snapdragon S4 Pro 1.7 GHz quad-core processor and a 13 megapixel camera.  It was introduced as a part of the spring line-up of NTT DoCoMo. The Optimus G Pro has a 3,000 mili amp-hour battery as compared to the 2,020 mili amp-hour battery of HTC Droid DNA, otherwise, the specs of both phones are similar.

The prioritized battery life is just to keep the 5-inch running all day, removing all gripes of customers.  In no way has the bigger battery made the phone bulky, at just 0.4mm thicker than Droid DNA, LG Optimus G Pro is quite light.

Although Sony has decided to stick to its 2,330 mili amp-hour battery in the new Xperia Z series too, it has an option for ‘battery stamina mode’ which shuts down apps when the screen is turned off and automatically restarts them when the screen is on. According to Sony, the feature has more effect when the number of apps installed is more. On the other hand, Huawei automatically turns off the transmitter circuit when data transmission is not in use, lowering battery consumption for its Ascend D2 series.

The battery life issue is not only limited to the phone manufacturers, the chip vendors too have made an approach to reduce the battery consumption of their processors. Tegra 4 is recently released by Nvidia. The chip is based on the ARM Cortex-A15 design and uses 45 percent less power than Tegra 3 under normal condition. This change is attributed to the second generation battery saver core and advanced power management. In efficiency, Tegra 4 could compete with ARM big.LITTLE architecture based processors, the first iteration of which combines the Cortex-A15 with frugal Cortex A7 on one die.

Also, there are talks of Samsung Electronics to use four of each in its Exynos 5 Octa processor, which will be used to power high-end smart phones and tablets. The due date for the products’ arrival has not yet been declared, but it would be much of a winner whenever it does.
