Call quality

Both smartphones are exceptional phones in themselves. The earpieces of both devices have a pretty clear and quite natural tone reproduction; even in noisy environments, you'd hardly have issues with any phone. The on-board microphones on the One M9 and the Moto X all perform top-notch; however, Motorola's flagship tends to insert a “slight tinge to our voice”.


Despite the larger battery at the back and the more power-efficient chipset, the One M9 has a worse battery life than its predecessor. It clocked in at 6 hours and 25 minutes in our battery benchmark test, which is less than One (M8)'s result of 7 hours and 25 minutes. Still, the Moto X sits lower in our battery hall of fame – its result is 5 hours and 45 minutes.

Battery life (hours) Higher is better
HTC One M9 6h 25 min (Poor)
Motorola Moto X (2014) 5h 45 min (Poor)
Charging time (minutes) Lower is better
HTC One M9 106
Motorola Moto X (2014) 176


Despite being the newer and better-spec'd phone, the HTC One M9 is not necessarily running circles around the Motorola Moto X 2014. Yes, it's more powerful and future-proof, but the Moto X still holds its ground. To sum things up, the HTC One M9 will woo customers with its sleek build and powerful hardware; meanwhile, the Moto X doesn't shine hardware-wise, but it still has what it takes to be an attractive and affordable alternative to a number of newer phones, the HTC One M9 included.
