A few weeks ago, just ahead of MWC, HTC unveiled their hotly anticipated new premium smartphone, the HTC One M9. We thought it would be interesting to see how the M9 measures up against the previous HTC flagship smartphone, the HTC One M8, so here goes.

Like the M8, the M9 is beautifully crafted and now features a stunning two-tone metallic design with 4 colour options. The shape of the M9, like the M8 is curved with some new angles which remind of us of the original HTC One. The M9 also boasts a new scratch-resistant coating, a tough sapphire glass lens on the rear facing camera and even better dual BoomSound speakers on the front which now come with Dolby surround sound. Like the HTC One M8, the M9 comes with a 5-inch display with a Full HD resolution of 1920 x 1080. Both have a pixel density of 441 pixels per inch so there's nothing to choose between them into terms of screen sharpness.

The Duo camera feature on the rear of the M8 has been changed for the M9 which comes with a single 20-megapixel rear camera with a dual LED flash. The camera on the front of the M9 is similar to the second rear camera on the M8 - it's an UltraPixel camera with dynamic exposure. New for the M9 is improved software which includes the HTC One Gallery app where you can store all your images including social media pictures in one place.

HTC have upgraded the specs on the inside of the HTC One M9. The M8 has a 2.3GHz Snapdragon 801 processor with 2GB of RAM whereas the M9 comes with the new octa-core, 64-bit Snapdragon 810 processor and 3GB of RAM for super speedy operation and transfer from one app to another. Interestingly initial tests on the HTC One M9 by Geekbench, who test smartphones and tablets to measure processing power, indicate that the M9 is likely to be one of the fastest smartphones currently available.

On the storage front, the M8 has 16GB of onboard expandable storage whereas the M9 comes with 32GB of built in storage which can be expanded up to 128GB with a microSD card. Battery-wise, the M9 also houses a large 2840mAh battery which offers a very impressive 22 hours of talk time on 3G and charges much faster with a 30 minute charge providing around 60 per cent of its total capacity.

The HTC One M9 comes with Android Lollipop 5.0 and an improved HTC Sense 7 User Interface. Sense 7 is more personalised with a revamped Blinkfeed and helpful suggestions of apps popping up depending on where you are . Sense 7 also has a new Themes app so you can customise fonts, icon styles, colours and wallpapers.
