System Performance

For system performance, we saw the Snapdragon 855 in the Galaxy S10 perform excellently, and there shouldn’t be any reason for the G8 to perform differently. It’s to be noted that the G8 is only our second Snapdragon 855 device we’ve received so the only comparison point we have is the Snapdragon variant of the S10.

Unfortunately, it looks like LG using an older version of the 855 BSP which is lacking some optimisations or lacking some configuration options which improve performance. Among the lacking features is the lack of boost mechanism for the top-app process groups, meaning the scheduler will be less aggressive than what we find on the Galaxy S10.

Let’s see how these differences end up affecting the G8’s performance:

PCMark Work 2.0 - Web Browsing 2.0

In PCMark’s web-browsing test, the difference ends up as quite major between the G8 and S10 as the former largely lags behind Samsung’s flagship, ending up with scores similar to the G7. The performance here reminds us of the initial benchmark scores from Qualcomm’s QRD855 reference platform in January, which also lacked some scheduler optimisations were commonplace in many of last year's Snapdragon 845 devices.

In the subsequent tests and final PCMark performance score we see the LG G8 lag behind the Galaxy S10, again scoring similarly to the QRD platform.

JS Benchmarks

Since our review of the Galaxy S10 it seems Google has updated the system WebView to a newer version which has had a notable impact on performance, improving things by several performance points compared to a few months ago. We haven’t had the opportunity yet to update our database with the newest figures, which is why in some benchmarks the new G8 scores better than some previously reviewed devices.

In WebXPRT on the other hand we see the less aggressive scheduler settings overshadow the new WebView improvements, and the G8 again end up with worse performance than the Galaxy S10.

System performance verdict

Overall, I’ve actually been quite disappointed with the performance of the G8, even though the benchmarks rank it relatively highly among Android phones. The core issue here I think is software as seemingly the G8 is lacking some of the framework boosters and more aggressive scheduler settings found in competing devices.

Where this is most noticeable is when switching between applications or something as simple as browsing different views in applications. Here the G8 is not only noticeable slower as the new Galaxy S10 in both SoC variants, but it’s also noticeably slower than many of last year’s Snapdragon 855 devices.

What is most shocking however is the fact that the G8 feels slower than the G7. In side-by-side comparisons between the two phones, the G8 is slower in opening a lot of applications or in-app views. This is extremely disappointing and clearly points out that LG has messed up somewhere in terms of the SoC’s BSP integration.

We hope LG will address this in the future with a firmware update, however users shouldn’t be holding their breath on the matter.

    How would I be out of my damn mind? The results are there, the display just isn't calibrated and isn't much of a step up from the G7. I suppose changing the display mode can remedy this, but of course for someone that isn't tech savvy, you would want the best out of your display, no?

    I guess what I meant to say its pitiful for not being accurate towards the color gamut. But dating back to my first G device, the G2, the IPS display was great.

    LG lost its imagination, we had very interesting phones from LG v10/20 G3/4/5/6, they had some problems but they had a "personality" and some good innovations, second screen, first with android 7.1, curved phone... Etc today they are just cheap ugly copies of Chinese phones, why copy the stupid useless notch while you had a more elegant and useful second screen? Reply

    Their implementation of "second screen" basically means they invented the notch. That's reason enough to damn them, even if they did far it better than Apple and the current crop of imitations. Reply

    So what has Samsung done to improve their design? It's the same curved display we have seen for the last few years. Reply

    Thanks for the review! Do you think the schedutil governor could be responsible for the performance in Work 2.0? (Assuming the G8 still uses schedutil) Reply

    One good thing about the recent LG V-series phones fro the US is that they support all T-Mobile bands. AFAIK only the Samsung S8 & S9 models do the same.

    So - the text says this takes micro-SD, but it's not in the specs list under 'storage'.

    "This is actually quite the competitive disadvantage for the G8, especially in the face of Samsung and Huawei’s newest triple-camera flagships."

    Why stop there? Compare everyone to Nokia's 5-camera spider-phone.

    To be fair the Nokia implementation of multiple cameras is just plain retarded. Reply
  • BedfordTim - Wednesday, May 1, 2019 - link

    Nokia's implementation is designed to reduce the overall thickness which, while being pointless, it achieves. The trade off is that multiple small sensors don't collect any more light than one big one.

    I think where they have failed is in the software as camera to camera variations need to be overcome to properly combine the images and gain the benefit of the monochrome cameras.

    Well, I think the multi-camera trend is silly in general. Nokia's is just the silliest. Reply
