Earlier this month, Samsung launched their newest flagship smartphone the Galaxy S6. With Apple's latest iPhone 6 flying off the shelves, Samsung promised to overhaul their premium smartphone and the S6 doesn't disappoint.

If you're an S5 owner and looking to upgrade, here's how the S6 really compares to its predecessor.

First up is the design and the S5 sported a plastic polycarbonate design and came with a removable back cover which meant that the battery was also removable and that you could access the microSD slot to expand the onboard memory. The Galaxy S6 is the first of the main S series of smartphones to boast a metallic and glass design with a curved metal band joining together a mirrored Gorilla Glass 4 panel on the front and rear of the handset. The battery is no longer replaceable and there isn't a microSD slot any more although there is a very respectable 32GB of built-in storage. The Galaxy S6 is slimmer than the S5 measuring just 6.8mm compared to 8.1mm and is 7 grams lighter, weighing in at 138 grams.

Samsung have certainly upgraded the display on the Galaxy S6. The screen size is the same as the Galaxy S5 at 5.1-inches but the S6 offers an impressive Quad-HD display with a resolution of 1440 x 2560 which gives it a magnificent 577 pixels per inch. This compares to the S5 with its full HD 1080 x 1920 at 432 ppi. In short, graphics on the S6 are going to be 30% sharper, plus the display on the S6 also comes in at up to 20% brighter.

At first glance, the camera specs for the S6 may look fairly similar to the S5. Both offer a 16-megapixel rear facing camera however the new camera on the S6 features smart optical image stabilisation (to avoid shaky, blurry shots) as well as a f1.9 wide angle lens for improved performance in low light conditions, plus the rear camera can be activated in less than a second. On the front of the Galaxy S6 is a 5-megapixel camera (up from 2-megapixels on the S5) which comes with real-time HDR (for photos that look more like what your eyes see) and 4k recording.

On the inside, the S6 has had a make-over. The Galaxy S5 comes with a Snapdragon 801 2.5GHz processor, 2GB of RAM and 16GB of expandable storage. The Galaxy S6 will be faster and more efficient with a 64-bit octa-core Exynos 7420 processor together with 3GB of RAM and the aforementioned 32GB of onboard storage. On the battery front, the S6 battery is slightly smaller at 2550mAh compared to 2800mAh in the S5, however the S6 can be charged wirelessly and benefits from super fast charging. You can get around 4 hours of usage from just a 10 minute charge.

The software for the Galaxy S6 as you would expect is also superior to that for the S5. The S6 comes with Android Lollipop 5.0 and the Samsung's TouchWiz has been improved so it's more efficient and less cluttered. In addition, the Galaxy S6 comes with pre-installed Microsoft apps as well as OneDrive which provides 115GB of space for a duration of 2 years. The fingerprint scanner is also more reliable and new for the S6 is Samsung Pay which is similar to Apple Pay and will be available in the USA later this year.
