Both phones have released in November and they’re slowly reaching the stores from all over the world, their designs are very different, so you’ll need to choose between all-plastic and all-metal, between a phablet with BoomSound speakers, and a smaller smartphone with a fingerprint scanner and which runs on the latest Android version.

Designs and Displays

The One A9 is very similar to the One M9 flagship, featuring a sleek aluminum body, curved on the edges and featuring two slim lines on the back: one at the top with the camera above it, and the other is located at the bottom. On the front side has only a physical oval button which has the fingerprint scanner integrated inside, but it lacks the BoomSound speakers which are found on the Desire 828. The phone comes in four color options of Carbon Gray, Opal Silver, Topaz Gold and Deep Garnet, it weights 143grams and measures 145.8×70.8×7.3mm. There’s a small similarity between the One A9 and Apple’s iPhone, but the latter has the rear camera positioned in the left corner, while on the One A9 is located in the center. The screen is an AMOLED, so its colors are very punchy and the images are pretty sharp, thanks to the Full HD resolution at 441ppi.

The Desire 828 phablet measures 157.7×78.9×7.9mm, it weights 183grams and its design is a mixture between the One X and a normal Desire phone. It’s made entirely of plastic and has a two color scheme, such as white with a brown frame, while the front panel is white and the screen sits on a protruding platform. The phablet looks rather sporty, but it doesn’t feel cheap. The screen has a diagonal of 5.5-inch and the supported resolution if Full HD at 401ppi.


The Desire 828 runs on Android 5.1.1 Lollipop and it’s powered by a Mediatek MT6753 octa-core 1.5 GHz Cortex-A53 processor which is backed by Mali-T720MP3 graphics and 2GB of RAM, while it allows you to expand its internal memory of 16GB up to 200GB.

The One A9 was released with Android v6.0 (Marshmallow) out of the box and inside it has a Qualcomm MSM8952 Snapdragon 617 octa core also clocked at 1.5GHz, but which is backed by 2GB of RAM, if the users choose the variant with 16GB of RAM, while the other model houses 32GB of storage and 3GB of RAM. Luckily, both models feature a microSD card slot for expansion up to 200GB.

Cameras and Batteries

HTC hasn’t bothered to build or order a different type of camera for the backs and fronts of the Desire 828 and One A9, so the pictures look identical whether they’re taken with the 13MP rear camera with OIS, or the 4MP Ultrapixel front camera with 1/3′ sensor size and 2µm pixel size.

The phablet requires a bigger battery and its capacity is 2800 mAh, while the One A9 has a very disappointing battery of 2150 mAh.
