Samsung has announced a new Galaxy S smartphone: the Samsung Galaxy S6, alongside its twin sister the Galaxy S6 Edge. The successor to the Galaxy S5 will be on sale for April 10. The Galaxy S6 Edge is a variation on the main device that has a display wrapping around the side, in order to display notifactions and other useful information.

Like the Galaxy Note Edge, the Galaxy S6 Edge has a display that is curved, creating additional screen real estate that can be used for notifications. It also has a new feature that lets you choose from one of eight colors to quickly glance at who's calling you when the phone is placed upside down.

The Galaxy S6 Edge is packed with all the same components inside as its flat cousin, except for a larger 2,600mAh battery pack. So lets get into those features and specs. (See also: Samsung Galaxy S6 launch as I thappened.)

Samsung Galaxy S6 Edge: Specs and new features

The new Samsung Galaxy S6 Edge is constructed from glass and metal rather than plastic compounds. It is less than 7mm thick, according to Samsung, and won't bend, they said. Nice dig at Apple, there.

The Samsung Galaxy S6 Edge is powered by 3GB of LPDDR4 RAM and its own octa-core Exynos processor. This is a 64-bit, 14nm system-on-a-chip processor. Samsung claims its processor is about 30 percent more power-efficient than before. It also says two separate quad-core sets are for separate specific purposes: one for battery efficiency, the other for performance.

The Samsung Galaxy S6 Edge will feature a Super AMOLED screen. Samsung said it was the best screen ever seen on a smartphone. This is a 5.1-inch Quad HD Super AMOLED display with a pixel density of 577 ppi. That ought to do it. Samsung said that the Galaxy S6 Edge should be easier to see outdoors and is about 20 percent brighter than the Galaxy S5. We can't wait to test that out.

Samsung also said that the battery should be the quickest-charging battery on the market, taking just 10 minutes to generate four hours of use. It is a  2,600mAh battery pack. This is bigger than is that of the Galaxy S6, presumably to power that additional screen space. Wireless charging is built in, as is the battery itself. A change for Samsung. It said this was a good thing, but we cannot yet fathom why that is. Any ideas? (See also: What to expect from MWC 2015 | Top stories and live video streams.)

Samsung Galaxy S6 Edge

The Galaxy S6 Edge will be an Android L device. TouchWiz is still present, but we are told it is much improved. We'll see.

Camera wise, Samsung beefed up its preexisting 16-megapixel camera sensor instead of bumping up the megapixels. The rear-facing camera features a F1.9 wide-angle lens, which should allow more light to hit the sensor when shooting in low-light situations.

The camera is also capable of real-time HDR and Smart OIS, which Samsung says has been refined since introduced in the Galaxy S4. Also, the Galaxy S6 uses an IR sensor to automatically detect and adjust white balance.

Samsung equipped the Galaxy S6 Edge with a 5-megapixel front-facing camera that also utilizes automatic real-time HDR and a wider lens. That is an impressive spec up front.

There's only one speaker, but it is a good one (according to Samsung). It would have to be, in order to be better than stereo speakers. Samsung gives you a pair of ergonomic earphones to say sorry. (See also: Samsung Galaxy S6 vs HTC One M9 comparison preview.)
