Call quality


The G3 has an advantage over the S5, which performs 'alright', but not great.

The G3, for its part, has a sufficiently-loud, noise-canceling microphone setup, that transmits voices with a satisfying level of clarity to the other side. The earpiece is also powerful enough to provide comfort during calls, and sound is, again, relayed without significant deterioration in quality.

Looking at the S5, its microphone is moderately-loud, but higher frequencies are boosted substantially, and sound a tad unnatural. As for the earpiece, loudness is just enough, and voices tend to be transmitted with a very slight, muffled quality to them

Battery life


At a glance, the LG G3 appears to have the upper hand over the Samsung Galaxy S5, at least in terms of battery capacity – its 3000 mAh user-replacable juicer is more spacious than the S5's 2800 mAh one.

Considering the G3's extremely pixel-dense, QHD display, however, we were not too surprised to see it trail the S5 in terms of total battery endurance, not least because Samsung's latest proved to be quite the soldier itself. Put in numbers, the Samsung Galaxy S5 managed the great 7 hours and 38 minutes, while the LG G3 only survived for 6 hours and 14 minutes. That's a sizable premium, and a win for the S5.

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.

Conclusion


So there you have it – two amazing flagships that will never fail at exchanging painful blows. If you haven't realized yet, this seeming quibble is exactly the type of mess you'll be in if you ever have to make a decision between the two. That is, unless you get your preferences straight.

In terms of overall design, we feel we can successfully argue that the LG G3 is the more attractive device of the two. The utilitarian GS5, however, will appeal to those looking for practicality over looks, and this has a lot to do with the fact that Samsung's flagship is dust- and water-resistant.

The G3 also has a seemingly superior, 5.5'' display, but the reality is that despite the extra resolution, you'll be hard-pressed to perceive a difference in clarity. What's more, content crafted for such a high resolution is not just rare – it's darn near non-existent. And all those pictures don't come for free – the hit in performance is exemplified by both synthetic and real-world benchmarks. That said, it's not like the S5 doesn't stutter, either. Unfortunately, our initial concerns about what this panel might do to battery life have materialized and that means longevity is a chink in the G3's armor.

And in terms of imaging? The shoe is now on the other foot, as the GS5's camera churns out slightly better stills and video overall.

So how do you choose? As we mentioned in the very beginning of this comparison, it ultimately comes down to your individual preferences, as each device has enough relative strengths to even out its relative weaknesses. We have no objective winner here – just different paths taken, both of which lead to the same great outcome.
