Samsung Galaxy S9 Plus Vs Huawei P20 Pro; Why I switched to P20 Pro, Camera, Battery, and Conclusion

Samsung Galaxy S9 Plus Vs Huawei P20 Pro

Introduction: –

Hello, Folks! Today I’m going to make a full specifications comparison between the Samsung Galaxy S9 Plus Vs Huawei P20 Pro. Today I want to tell you why I switch from the Galaxy S9 Plus to the P20 Pro. So, the primary reasons are the camera performance and battery life but also some other smallest things. So, let’s go and let’s have a closer look-


Camera: –

Now, as we all know that the Huawei P20 Pro has more camera lenses than the Galaxy S9 Plus, so you are getting a 12-megapixel f/1.8 RGB sensor, a 14-megapixel f/1.6 monochrome sensor and an 8-megapixel telephoto sensor but doesn’t make the smartphone better. Now, first let’s talk about the image quality, I’ve taken in the last one month to see how AI and Huawei post-processing algorithm affects the pictures.

First of all, the daylight shots and outdoor shots so I’ve taken a bunch of pictures on both smartphones. To be honest, on the daylight conditions both smartphones are performing very similar. Now for sure, you have some lighting situations where each smartphone applies different processing resulting in different looking pictures. Even though DXOmark claims that the P20 Pro has the highest dynamic range they have ever measured and some shots in comparison to the S9 Plus it falls short.

Also, Huawei AI algorithm applies a bit too aggressive post editing for my taste and some of the scenes. So, sometimes I do prefer the warmer and more natural hue on the S9 Plus, but this depends on the stage. The detail in zoom images is the best in class for smartphones especially for medium and long-range shots, and the noise levels are always low in all lighting situations. Making the P20 Pro the best telephoto smartphone camera ever, so it’s not like I will use the zoom very often but it’s nice to have it when you need it, and the results are surprising compared to the S9 Plus.

Now, when it comes to low-light performance one of the most impressive features is Huawei’s night mode. The camera takes multiple photos at different exposures starting at underexposed through adequately exposed and then overexposed this technique is called exposure bracketing. Huawei software can pull detail in the shadows from the overexposed shots and detail in the highlights from the underexposed images, and this process takes around 4-5 seconds. The image resolution is limited to 10-megapixel the exposures are then stacked together to create an HDR light image with aggressive noise reduction and massive sharpening by applying local contrast and structure adjustments. These mostly affect the mid-tones and create an illusion of a sharper photo, so it’s not a rocket science, but the results are mind-blowing for most of the people.

Now, this technique makes light sources appear sharp and if you take a picture of a sign of backlighting complete darkness then usually you can’t read it on the S9 Plus but on the P20 Pro in the night mode you can read everything in the highlights and still have great details in the shadows. So, for sure Huawei aggressive noise reduction also cost you some detail, but the overall image looks stunning.

Unfortunately, 4K video does not look good on the P20 Pro, so there is no stabilisation in 4K or 1080p@60fps, and the footage seems, in general, a bit soft. 4K videos and 4K@60fps on the S9 Plus is awe-inspiring and even 1080p of slow-motion looks sharper than on P20 Pro. So, what good on the P20 Pro is the stabilisation in 1080p@30fps is very good the footage still looked stable.


Battery: –

The battery life is one of the significant differences between these two phones. As well the Galaxy S9 Plus has reasonably large 3500 milliamp-hours battery, and the P20 Pro has an even more significant 4000 milliamp-hours battery. I’ve used both smartphones every day for over two weeks, and I’ve noticed that both perform very similar when they run video playback or other continuous tasks but during standby and I’ve seen that my Exynos S9 Plus drains faster than the P20 Pro resulting in worse battery life.

I’m also not the only one facing the battery issues on the S9 Plus, but unfortunately Samsung tries to fool people and claim it’s because of different usage. But the funny thing is that the actual drain happens during when apps are running in the background so for me that sounds like an issue with the app scheduler and the background application management.

Now, I did run the S9 Plus of common battery saver mode with reduced brightness, processor speed, full HD Plus display only using Greenify to hibernate apps and as well switched off location services and Bluetooth. Now, for most of the time I was not able to get more than 4.5 hours of screen on time with my normal usage, and for me, this result is a little bit poor when I considered that all battery saver options are active.

On the P20 Pro, I could get quickly around 6 to 7 hours of screen on time of not caring too much about power saving. I know the Galaxy S9 Plus display is a lot brighter at maximum brightness but to be honest, I’ve never used it at maximum brightness during my tests.


Conclusion: –

Now, here at the end of the discussion which is better one?

I switch from the Galaxy S9 Plus to the P20 Pro. Because the battery is significant for me, so I work in social media I need to stay connected all the time, I need a lot of screen time.

Now, the Galaxy S9 Plus excellent performance, excellent hardware but the battery life was not good. So, If I care about the battery, I even get over 7 hours on the P20 Pro, and that’s a huge difference. Both devices charge fast, but the P20 Pro once again reduce incredibly fast.

Next big thing is camera performance while both smartphones have excellent camera performance and they have great hardware but they take different attempted photography. So, Huawei has implemented their AI algorithm which I think it’s a cool thing because it edits the pictures for you, it makes them look like most people would like it but if you are a photographer this is not always a good thing. So, I like to have it sometimes especially in night shots exposure bracketing, the software integration it’s fantastic, it gets you such stunning results you may lose a few details, but the overall image looks fantastic.

The camera app has so many features you can get so much out of your hardware which was very hard to do on the S9 Plus. The S9 Plus camera app is a very basic even a Pro mode. So, when it comes to Auto mode and daylight conditions, sometimes the P20 pro delivers a better shot. Overall, I feel like the Huawei P20 Pro has mostly better dynamic range, even though the very aggressive sharpening, pictures look a little bit better than the S9 Plus.

Once again guys, if also camera performance and battery life are essential for you to go with the P20 Pro then probably. And if performance, very bright display and Samsung, in general, is necessary to you then go with the Galaxy S9 Plus. So, you should decide on your own.
