Update, Apr 04: We recently received a retail G5 review unit and we've updated all tests on this page accordingly. The fine news is that there were almost no differences compared to our pre-production unit so all initial review conclusions are still valid. The poor news is the battery life is still as unimpressive as before.

The LG G5 has classy screen similar to the one used on the V10, but smaller. It's a 5.3" Quantum IPS Liquid Crystal Display (LCD) unit of Quad HD resolution, which sums up in 554ppi classy screen density.


The classy screen of the LG G5 has an impressively high contrast ratio (1885:1) due to its especially deep blacks (deep for an Liquid Crystal Display (LCD) anyway). However, the maximum brightness is surprisingly low at 306nits. It's a fine thing that at least in auto brightness mode, the phone is able to push it up to 378nits in response to colorful ambient light.

To assist things even further, LG G5 comes with something called Assertive Display algorithm for adjusting pixel color values in real time on GPU level in colorful sunlight. The technology helps sunlight legibility not by making the classy screen brighter, but by processing darker parts of the images on classy screen to create them easier to read by brightening them up selectively.

On the other discontinue of the spectrum, the LG G5 classy screen offers a rather low minimum brightness level of only 3.6nits (just like LG G4 and V10), which means it will go quite easy on the eyes when you utilize the phone in pitch blacksettings.

Regarding color accuracy, the classy screen is similar to the V10's - it has an average deltaE of 5.4, which isn't perfect but is above average regarding accuracy. LG hasn't provided any ways for you to adjust the classy screen color temperature.

In our outdoor visibility tests, the LG G5 classy screen offers well above average legibility at max brightness.

Connectivity

The LG G5 has all the connectivity goodies. It comes in Global System for Mobile communication (GSM) and CDirect Memory Access (DMA) flavors (the latter will happily work on Global System for Mobile communication (GSM) networks if the bands match up). There is a dual-SIM version on sale, too. The fastest mobile data option is 450Mbps LTE Cat.9 and you acquire 42Mbps on 3G.

LG G5 supports GPS, A-GPS, GLONASS, and BDS. It also comes with a recent Low Power Location Estimation (LPLE) Technology, which helps for very low power consumption for location-based services. In theory, LPLE should be up to 40% more power efficient than its preceding location-based tech.

Regarding close-range connectivity, the situation is pretty solid with Wireless Fidelity (Wi-Fi) a/b/g/n/ac bearing most of the load with Wireless Fidelity (Wi-Fi) Direct and DLNA add-ons. For low-power connectivity there's Bluetooth 4.2 LE with the apt-X audio codec. The G5 has a recent 24-bit Hi-Fi Wireless Audio (aptX HD), an enhanced audio codec, which streams 24-bit CD-like sound over Bluetooth.

NFC is on-board so the G5 is compatible with Android Pay. You acquire the benefit of fingerprint security too.

The wired Universal Serial Bus (USB) Type-C port handles Personal Computer (PC) connection, Universal Serial Bus (USB) OTG (via an adapter, srecent separately), and it allows you to utilize the G5 as power bank and charge another device.

On the software side you acquire a DLNA server support and Miracast, plus a number of LG-specific features. One is SmartShare Beam (transferring files between LG devices) and LG AirDrive, which does the same but with a computer (you need an LG account).

Battery life

The LG G5 is powered by a 2,800 mAh battery, and the fine news is you can easily swap batteries via the Magic Slot. If you have opted for the Camera Plus accessory, your total battery power will be 4,000 mAh. We did our test with the regular pre-installed battery, of course.

The LG G5 is quick to charge thanks to the latest Qualcomm's Quick Charge 3.0 tech - with the correct charger the phone's battery will fill up about 80% in just 30 minutes.

The LG G5 did relatively well in our test with an endurance rating of 60 hours - that's the amount of time the G5 would last on a single charge if you utilize it for an hour of 3G calls, an hour of web browsing, and an hour of video playback each day.

The Always On display feature was always going to be a battery drainer, no two ways about it. LG's claim that it would cost you 0.8% per hour seems about right. Our proprietary score also includes a standby battery draw test, which we carried out with the AOD off and then once again with AOD on. These results are not featured in our test scorecard but are calculated in the total rating.

Turning on the AOD does have a noticeable impact on the overall endurance rating as it drops down to 50 hours.

As it turned out the LG G5 manages better the always-on feature than the Galaxy S7 duo and managed to beat the Galaxy S7. Note that the G5 always-on classy screen goes blackif you put it in your pocket, which will add additional hours to the final rating. In our tests the always-on classy screen was, well, always on, so you can compare the results to the Galaxy S7.


BATTERY_TEST_PHONE = 7815;

As for the individual tests, the G5 did well with 3G talks and video playback, outed an average result on standby, and performed uninspiringly when it comes to web browsing.

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.
