Samsung Electronics Co Ltd (KRX:005930)’s Galaxy S7 and S7 Edge have 3,000mAh and 3,600mAh battery capacities respectively, which make them two of the smartphones with the best battery life on the market at the moment. Samsung used Exynos chips in these devices to solve the battery issues that marred the Galaxy S6’s battery life. The Galaxy S7 has a confirmed battery time of a full day based on average-to-extensive usage, according to various benchmark tests. The battery life, however, largely depends on the nature and intensity of the usage. The Samsung S7 and S7 Edge’s batteries can be optimized further by using the Android Marshmallow’s “Doze” feature, which is preinstalled on the devices. The Galaxy S7 also has a Qi/PMA wireless feature through which you can charge the device wirelessly using special charging pads. The Galaxy S7 Edge beats its major competitors by a clear margin in various battery tests, including full video playback tests and Wifi browsing tests.
