Images taken inside a Chinese battery factory, which claim to reveal the new battery pack for the Samsung Galaxy S6, could confirm reports that the device will have a 2,600mAh capacity. That’s lower than the Galaxy S5’s 2,800mAh capacity, but the Galaxy S6 should be more efficient.

While these don’t look much like existing Samsung smartphone batteries, they do have a model number that reads “EB-BG925ABE.” That’s very similar to the “EB-BG900BBC” model number you’ll find on Galaxy S5 batteries sold on Amazon, PhoneArena notes.

What’s more, that battery’s model number contains the digits from the Galaxy S6 Edge’s model number, which is believed to be SM-925X.

It’s certainly possible that these packs are genuine, then. The reason they don’t look quite as neat as other Samsung batteries could be that these aren’t designed to be removable; the Galaxy S6 and S6 Edge are expected to have non-removable back panels.

Don’t be put off by that 2,600mAh capacity, either; while it is lower than the Galaxy S5’s battery capacity, Samsung’s new devices are expected to use much more power efficient processors, and they should have much-improved software that won’t be as draining as TouchWiz.

It’s also worth noting that although they should have Quad HD displays, tests on the Galaxy S5 LTE-A, which has a 5.1-inch Quad HD screen, proved that its Super AMOLED panel consumed no more power than the 1080p alternative in the regular Galaxy S5.
