Samsung's Galaxy S7 Edge could have a 38 percent larger battery compared to the Galaxy S6 Edge, according to specs revealed in FCC filing (click FCC ID Label and Location).

The filing, which every phone vendor has to submit before its products can sell in the US, points to a 3,600mAh battery for the S7 Edge, which is expected to have a 5.5-inch screen. In contrast, last year's smaller S6 Edge sported a 2,600mAh battery to power the 5.1-inch screen.

Once the cream of the phone crop, Samsung is hoping for a hit with the Galaxy S7 and S7 Edge. Although the Galaxy S6 Edge was generally well received for its curved metal and glass design, Samsung has lost ground in the global arms race. Buyers are gravitating to more budgeted devices, and brands like Huawei, ZTE, and Xiaomi are benefitting from the shift.

Samsung did not reply to a request for comment.

Remember that battery capacity doesn't always translate to longer battery life: the efficiency of the processor makes a huge difference in how long the battery lasts between a charge. It's also tough to forecast what sort of additional impact Android 6.0's Doze feature, which hibernated phone processes when the phone has been idle for hours, will have on the S7 Edge's battery life.
