The Galaxy S7 is expected to pack plenty of new technology, and it looks like that could include a powerful battery. A new rumor claims the device will offer an impressive 17 hours of video playback.

That’s according to Eldar Murtazin, a Russian tech blogger with a mixed track record when it comes to smartphone scoops. In a follow-up comment he adds that the device should last “2 days easily” on a single charge.

We’d treat this one with a grain of salt, though it’s not as crazy as you might think. Samsung already promises 13 hours of video playback for the Galaxy S6 and 15 hours for the Galaxy Note 5. Apple even boasts 14 hours for the iPhone 6s Plus.

So the Galaxy S7’s new battery may not be a huge upgrade, but it should still be a pretty nice improvement. The phone is also rumored to pack a relatively small 5.1-inch display, which makes that battery life even more impressive.

The Galaxy S7 is expected to offer a Quad HD pixel resolution, a Snapdragon 820 or Exynos 8890 processor, a 12-megapixel rear camera, 4GB of RAM and a USB-C charging port. It should run Android 6.0 Marshmallow out of the box along with some of Samsung’s own software and apps.

At this point it seems safe to say that we’ll see the Galaxy S7 unveiled next month at Mobile World Congress. TechnoBuffalo will be there covering the entire show, and we’ll be sure to checkout the new phone and any other surprises the company might have planned.
