Call Quality

Call quality is very good on both the Note 4 and the One (M8). The earpiece of the Note 4 produces clean sounds, with no audible distortions, but the volume could have been a bit louder, while the M8 offers very good clarity and volume. We have no complaints about sound on the other end of the line, as both sound clear and loud.


Large devices like the Galaxy Note 4 have the benefit of more physical space coming with size, which allows manufacturers to cram in larger batteries. The Note 4 in particular has a spacious 3220mAh juice pack, and there’s a number of benefits to that . What we’re mostly interested in is battery longevity under average use, and that’s why we have our battery test where it’s this kind of non-stop use that phones are tested against, and screen draw is normalized by pre-calibrating displays at 200 nits. Good news is that the Note 4 ends up being one of the top battery performers on our battery test, scoring an impressive 8 hours and 43 minutes. The HTC One (M8), on the other hand, comes with a 2600mAh battery, and while it does score fairly well at 7 hours and 12 minutes, it still lasts significantly less than Samsung’s Note 4.

We should note that the Galaxy Note 4 has the benefit of a user-removable battery, while on the M8 there is no easy way to swap batteries.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

An important factor to consider when choosing between the Note 4 and the One (M8) is the size difference - the 5.7” Note 4 is larger and that comes with its pros and cons.

If we take size out of the equation, though, the Note 4 has a clearly pronounced advantage: its brilliant Quad HD display is a beauty to behold with its accuracte colors, while the screen on the M8 does not look bad, but lacks that color fidelity, then, the Snapdragon 805 system chip on the Note 4 is an improvement over the 801 on the M8, and finally, the 16-megapixel optically stabilized camera is among the best smartphone shooters out there, while the M8's UltraPixel camera is not all that capable.
Where M8 still comes up is the stylish unibody aluminum body, but hardware-wise it is just not as impressive.

Picking between the Samsung Galaxy Note 4 and HTC One (M8) also comes down to price, and that’s where the M8 has a clear advantage with a full, off-contract price of around $600 (540 euro), while the Note 4 carries a full retail cost of $825 (770 euro). So which one would you pick?
