The One M9 and A9 have a similar body shape and the same horizontal lines at the top and bottom, just like Apple’s iPhone 6S. Actually, the American Giant accused HTC of ripping off the iPhone 6S’s design, but there are some differences between the two models. Also, in this article we’ll highlight the differences between the two HTC devices and you’ll figure out which phone is worth buying.

Designs and Displays

The One A9 doesn’t have dual front facing speakers, Dolby Audio smarts with BoomSound technology, as the manufacturer preferred to use a single speaker, but it has something that the One M9 is missing: a fingerprint scanner hidden inside the oval home button. The One M9 has a square camera lens located below the line from the top, while the One A9 has a smaller circular camera sitting above the line, in the center.

The One M9 measures 144.6×69.7×9.6mm and it weights 157grams. The One A9 is 14 grams lighter, but it’s much slimmer, measuring 145.8×70.8×7.3mm. Both devices have a screen with a diagonal of 5-inch, which supports a Full HD resolution at 441ppi, but the M9 uses a Super LCD3 technology, which displays colder tones than the AMOLED panel that was used for the One A9.


The advantage of the One A9 is that it came loaded with Android 6.0 Marshmallow out of the box, while the flagships is planned to receive this update. Anyway, the ladder has a much more powerful processor, benefiting from the latest Qualcomm MSM8994 Snapdragon 810 octa core CPU clocked at 2GHz, which runs very fast with 3GB of RAM, but the ones who bought this model complained that it heats up badly after a few minutes of use. The One A9 is powered by a Qualcomm MSM8952 Snapdragon 617 octa core processor which runs at 1.5GHz and it supports either 2GB of RAM (if the internal memory has a capacity of 16GB) or 3GB of RAM (32GB of storage). The One M9 has an internal memory of 32GB and likewise its mid-range sibling, it provides a microSD card slot for expansion up to 200GB.

Cameras and Batteries

Both phones have a front camera of 4MP (Ultrapixel) which records Full HD videos and takes great selfies in low light conditions. The One M9 sports a rear camera with a higher resolution of 20MP, but the 13MP main camera of the One A9 has in addition optical image stabilization.

The One M9 has a bigger battery of 2840 mAh, which lasts approximately 22 hours if the users make voice calls over 3G, while the One A9 is powered by a 2150 mAh battery, which withstands 16 hours.
