Prepare for a major upgrade in processing and graphics performance from next year’s Android-powered flagships. Qualcomm today announced its next-generation Snapdragon processors with 64-bit architecture, which promise a better mobile computing experience in almost every way.

In addition to support for 4K Ultra HD displays, the Snapdragon 808 and Snapdragon 810 processors are expected to bring even faster LTE connectivity, better graphics for your games, and blazing-fast devices you haven’t experienced on Android before.

The new Galaxy S5 boasts a ton of fancy new features, but one of the things Samsung has been pushing most since the handset was unveiled back in February is its built-in heart rate sensor. But just how revolutionary is that new sensor?

Well, as it turns out, not very. In fact, based on the hands-on video below, you can get the same results using your smartphone’s camera and LED flash with an app like Heart Rate Monitor from Runtastic.

HTC finally made its much-anticipated HTC One M8 official today. In addition to a gorgeous aluminum unibody design, it boasts all-new internals, a larger display, improved BoomSound speakers, and HTC’s latest Sense 6 user interface.

But how does it stack up against competitors like the Samsung Galaxy S5, the Sony Xperia Z2, and even the Apple iPhone 5s? Our in-depth comparison chart makes it all clear — and helps you decide which of today’s flagships is worth your hard-earned cash.

HTC’s latest promotional video for the upcoming “All New HTC One” teases the handset’s “sleeker” unibody construction, which is both taller and thinner than the original model. The first HTC One had a plastic chassis that held the front and rear aluminum panels together, but HTC appears to have eliminated that for its latest flagship.

Just as expected, Samsung unveiled its flagship Galaxy S5 at Mobile World Congress on Monday evening. In addition to fancy new features like a fingerprint scanner and heartbeat sensor, the handset boasts the latest Snapdragon 801 processor, a 1080p Super AMOLED display, and a 16-megapixel rear-facing camera with rich tone HDR, selective focus, and more.

But how does the Galaxy S5 compare to some of its competitors, like the iPhone 5s, the new Sony Xperia Z2, and its cousin, the Galaxy Note 3? We’ve put together a handy comparison chart below that makes it all clear — and may help you choose the best handset for you.
