And that is good news for the audiophiles. The HTC Desire 816G has a pair of front-facing BoomSound stereo speakers. If you get this phone, you will require a microSD card. Installing a game like Asphalt 8 and clicking a few picture will fill up the internal memory. The HTC Desire 816G comes with 8GB of internal storage of which about 4.33GB is available for use, which frankly speaking is not enough. It will be able to run most of the graphics-intensive games (Asphalt 8: Airborne for instance), however, the graphics will disappoint you.
If you're a hardcore gamer and graphics-intensive games are your thing, the Desire 816G is not meant for you. In Geekbench 3, the Desire 816G scores 352 points (single-core) and 1179 points (multi-core). Stick to the basics and the device will sail through.
The device comes with 1GB of RAM (the Desire 816 has 1.5GB) therefore multi-tasking could be an issue if you're really pushing it.
