Samsung Galaxy S9 Plus Review – One Of The Best Big Phones



Samsung Bixby Voice Assistant:


Bixby is Samsung’s voice assistant which Samsung made to compete with the Google Assistant and Apple’s Siri. Bixby has been upgraded on the Galaxy S9, however, it’s slow when trying to understand commands.


Sometimes Bixby misinterprets the commands, Google Assistant and Siri does a better job in this area.


Bixby Vision:


Bixby Vision is a unique software that was built into Bixby Home, Samsung internet, the gallery, and the camera. The feature was developed to give you a deeper understanding of whatever it is that you’re looking at.


This feature works by using object recognition to identify landmarks or businesses around you or to translate words.


There’s a feature called live translate which gives you the ability to point your camera at an object or page with words on it and it will translate the words from one language to another.


This is a great feature that will come in handy for many smartphone users. However, you must have data in order to use this feature.


Biometric Authentication Has Been Improved:


The facial recognition feature and the iris scanner has been improved from its predecessor. These two features now work together to unlock the phone within a fraction of a second, Samsung refers to this as intelligent scan.


Samsung implemented the facial recognition feature and the iris scanner to rival Apple’s Face ID. However, Apple’s biometric authentication system is more secure and more advanced than that of Samsung.


The Galaxy S9 Plus does a 2D scan of your face when using the facial recognition feature. This works but I wish Samsung didn’t have to sacrifice security to make this work.


Samsung Galaxy S9 Plus Hardware And User Interface:


The Galaxy S9 Plus comes with the Qualcomm Snapdragon 845 chipset or Samsung Exynos 9810 and it works on CDMA and GSM networks in the US and China.


Galaxy S9 Plus comes with 6GB of RAM, as a result of the new chipset and the 6GB of RAM this phone is one of the fastest Android phones on the market. This phone is noticeably faster and more responsive than the Galaxy S8 Plus from last year.


The Galaxy S9 Plus comes with the Android 8.0 Oreo operating system, 64GB or 128GB of internal storage which is expandable up to 400GB via the microSD card slot.


The Android 8.0 Oreo operating system provides an extremely clean user experience.


Samsung Galaxy S9 Plus Camera:


The Galaxy S9 and Galaxy S9 Plus are the first phones to feature dual aperture technology. These phones are also the first phones to feature a f/1.5 aperture. That’s the widest aperture that’s ever been placed on a smartphone.


As a result of the wider aperture and the dual aperture setup, the Galaxy S9 Plus takes amazing photos. The dual aperture technology will automatically switch between a f/1.5 aperture and a f/2.4 aperture.


When taking photos in a dark setting the f/1.5 aperture will be used. The wider aperture allows more light into the photos which produce great photos in a darker setting.


When taking photos in a well-lit setting the f/2.4 aperture will be used. The smaller aperture will reduce the amount of light in the photos which will prevent the photos from being overexposed.


As a result of this, the photos taken in a well-lit setting are rich and vibrant and they look extremely natural.


The Galaxy S9 Plus takes better photos than that of its predecessor. The dual aperture setup allows the Galaxy S9 Plus to take in more light while reducing the amount noise.


The photos taken with the Galaxy S9 Plus are brighter in comparison to photos taken with other smartphones.


The cameras on the Galaxy S9 and Galaxy S9 Plus are different. The Galaxy S9 Plus has the same dual-lens camera feature as the Galaxy Note 8.


As a result of this, the Galaxy S9 Plus has a telephoto lens one lens will allow you to optically zoom-in photos without sacrificing the quality.


While the other lens will enable Samsung’s Live Focus which works great when taking portrait photos.


Samsung Galaxy S9 Plus Selfie Camera:


The selfie camera is the same camera that’s present on the Galaxy S8 Plus. It’s an 8MP camera which has autofocus. The photos taken with this camera are slightly oversaturated in comparison to the photos taken with the primary cameras.


The camera app on this phone is complex, however, it’s extremely user-friendly. Whether you’re trying to toggle from one camera to the other or change the mode it’s extremely simple.


The Galaxy S9 Plus can record 4K video as 60 frames per second (fps). The video quality is good, however, this mode does not have optical image stabilization.


You also have the ability to record 4K videos at 30fps and you also have the ability to record video at normal speed in the HEVC format.


Videos recorded in the HEVC format are compressed so they end up having a smaller file size than videos that are not recorded in HEVC.


Super Slow-Mo Video:


The Galaxy S9 Plus has the ability to capture slow-mo videos at 960fps with a 720p HD resolution. This is a great feature that works very well when recording videos in a well-lit setting.


However, the quality is not as good when recording in a darker setting.


Samsung Galaxy S9 Plus Battery Life:


The Galaxy S9 Plus comes equipped with a 3,500mAh non-removable battery. The battery life on this phone is comparable to the battery life on the Galaxy S8 Plus from last year.


The battery will last for one full day of moderate use. A 3,500mAh battery is a big battery and the Galaxy S9 Plus is extremely efficient.


Based on these two factors I assumed that the battery life would have been improved from that of its predecessor, but it hasn’t.


Most smartphone users would like to have a longer battery life on their phones. However, this is something that many smartphone manufacturers have been struggling with for quite some time now.


Samsung and the other smartphone manufacturers have to find a way to significantly increase the battery capacity in their phones without making the phones too thick or heavy.


The Galaxy S9 Plus comes with fast charging technology the phone can be fully charged in roughly one hour and forty minutes.


My Final Thought:


The Galaxy S9 Plus is a big powerful phone, with a 6.2-inch curved screen. But it’s not a major upgrade from its predecessor.


If you have an old phone and you would like to get an upgrade and you like big phones. Then I would recommend getting this phone.


However, if you have the Galaxy S8 Plus, I would not recommend upgrading to the Galaxy S9 Plus. I would recommend waiting for the Galaxy Note 9 which will arrive later this year.


Please let me know your thoughts about the Samsung Galaxy S9 Plus in the comment section below.



  1. Ok, this is one of the coolest product reviews I have come across. Man, you read my mind as if though. I was actually going through the process of getting one of those on contract.

    Thanks to you now I know a lot of features I never knew existed before now.

    What would you say if asked to compare the Galaxy S9 latest with the new iPhone as well?

    • Thanks Richard, I like both phones, they have their strengths and weaknesses. For example the Galaxy S9 has a better display screen while the iPhone X has a more secure user authentication system. The Galaxy S9 has a fingerprint sensor and a headphone jack but the iPhone X does not. They are both great phones which one you choose depends on what platform you prefer, some people prefer Android, some people prefer Apple.

  2. Awesome review. I still have Samsung S7 Edge and I think I’ll wait for a few more generations of Samsung for me to make the change haha.

    Although I do like the display size of the phone, I’m a sucker for big screens!

    I really don’t understand the hype behind AR Emoji. Is it a pointless feature for most phones these days?

    • The Samsung Galaxy S7 Edge is a great phone, you should continue to use it until you’re no longer happy with it. I think Samsung needs to work on the AR Emoji a bit more. Samsung Galaxy users may appreciate the AR Emoji more if Samsung can get it to look like the person.

  3. Samsung galaxy s9 is a big phone. I love big phones because I often watch movies and play video games on my phone. I enjoy the big screen quality.

    The old samsung had a horrible finger print sensor placement, which is right next to the camera. It is very confusing. It is good that they changed the location now so that it is easier to find it.

    I have to admit that samsung phones does a really good job for their cameras. There is an old saying that if you want a good phone with a good camera, Samsung phones are the most beautiful choice you can make.
