Moto G5S Plus review

The 5.5-inch FullHD display scores high marks

The Moto G5S Plus comes with a 5.5-inch display - that's the 'Plus' speaking. It's a FullHD panel, an IPS one, and has a conventional RGB arrangement. It also has a pixel density of 401ppi.

In our testing, the Moto G5S Plus did well to post a solid 616nits of maximum brightness - that's more than pretty much any of its competition. That's in auto mode, and if you toggle it off you'd be able to get up to 480-ish nits - not bad either. Add to that the reasonably dark blacks, and you're looking at contrast of above 1300:1 - a sign of a good LCD. Minimum brightness is around 6nits, so night-time viewing in complete darkness shouldn't be an issue either.

Our sunlight legibility test puts the G5S Plus in the 'average' bowl - the main competitors are in the same ballpark with both the Mi A1 and the Honor 7X marginally behind the Moto. The Nokia 6 (the old one) is a bit better, though we can't blindly attribute the same result to the 2018 model without testing it.

Color accuracy isn't spectacular and even if we're not ones to fret over it, the bluish whites/grays remain visible. We measured an average DeltaE of 4.8 (not bad, actually) in the Standard display mode, with whites off by about 9 units. Vibrant mode redistributed the individual deltas somewhat differently, but kept the average mostly the same and whites didn't lose their blue tint.

Motorola Moto G5S Plus battery life

The Moto G5S Plus has a Snapdragon 625 under the hood. Motorola figured that since the chip is mightily efficient, going overboard with battery capacity is unnecessary and fitted a reasonably-sized 3,000mAh cell.

This proved more than adequate in our testing where the Moto G5S Plus just missed the 10-hour mark in video playback by a minute and checked in an almost full 12 hours of web browsing before calling it quits. The phone excelled in 3G voice call endurance (close to 27 hours) and standby times were good too. That adds up to an overall endurance rating of 81 hours.

Our endurance rating denotes how long a single battery charge will last you if you use the Motorola Moto G5S Plus for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritties. You can also check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.

The provided TurboPower charger will get you from flat to full in a quick 1:45h though the initial rate isn't all that great with the first 30 minutes only giving you about 25% of charge.

Audio output starts on the wrong foot, but quickly improves

The Motorola Moto G5S Plus had surprisingly poor output with an active external amplifier. Its signal to noise ratio and intermodulation distortion were so bad we would have suspected an issue with our test unit, but its smaller brother had the exact same behaviour so it appears Motorola did something wrong here. Loudness was impressively high, but that's not quite enough to make up for the sub-par quality of the output.

The good news is that the phone performed impressively well with headphones, which is probably the test most people care about. Loudness remained as impressive, while the clarity was among the best we've seen. Normally headphones tend to degrade the output, but with the Moto G5S Plus they improved it from mediocre to one of the best in the market.

Loudspeaker volume reaches new heights

The Moto G5S Plus has a single loudspeaker, a bottom-firing one, but boy, is it loud. It's the second loudest unit we've tested actually - a few decibels short of the HTC U11+, which claimed the crown recently. It's not amazing in the low end of the frequency range, but then few phones are.
