Samsung Galaxy S9 & S9+ Reviewed - BE FORWARD

If you’re looking for a used smartphone, you have a wide range of choices available from dozens of different brands. However, the one company that gives Apple a run for its money is Samsung and its Galaxy series, based on the popular Android platform.

Like Apple’s iPhone, the Samsung Galaxy series has a variety of different editions and models that can make it a little tricky to figure out which is the best fit for your needs. Here, we take a look at the similarities and differences between the Samsung Galaxy S9 and its Galaxy S9 Plus upgrade, the most recent in the series of best-selling smartphones.

Samsung Galaxy S9 vs S9 Plus Specs

Size & Build Quality Comparison

The most obvious difference between these two devices is their display size—with the Samsung Galaxy S9 Plus you get a display of 6.2 inches, while the Samsung Galaxy S9 offers 5.8 inches. That discrepancy of 0.4 inches may seem small, but it makes a big difference when watching videos, playing games, or browsing the web.

Material & Camera Build

The material used to make both phones is just about the same, with no evident differences in their build quality and materials. The quality of the touch glass is the same and so are the cameras, except that the Galaxy S9 Plus has an extra camera with a telephoto lens for shooting objects that are farther away.

While both have the same 8MP front camera with LED flash, the quality and capabilities of the rear cameras differ due to the Galaxy S9 Plus offering an extra lens, as mentioned above. This additional lens enables 2x telephoto zoom that brings the object you are shooting even closer to you in vivid detail. Apart from this, the primary cameras of both smartphones offer 12 MP with dual aperture to let in more light and capture more of your subject than ever before.

Performance Comparison

Both the Samsung Galaxy S9 and Galaxy S9 Plus run on the same operating system, “TouchWiz”, which is based on the Android 8.0 platform. The most prominent difference regarding overall performance is the amount of RAM available for each model, with the Galaxy S9 offering 4GB RAM and the Galaxy S9 Plus with 6GB RAM—a difference of 2GB.

Processor & Storage

Both versions of the Galaxy S9 flagship have the same 2,800 MHz Kryo 385 64-bit Octa-Core processor. They also come with the same level of internal storage options of 64GB to 256 GB, which can further be expanded to 400 GB via external storage cards to store even more of your videos, photos, and apps.

Overall Performance

Even with many apps open, both the Galaxy S9 and Galaxy S9 Plus offer a smooth, lag-free experience, however the extra RAM added to the Galaxy S9 Plus makes a noticeable difference when running more intensive apps or games. If you’re a heavy smartphone gamer, the Galaxy S9 Plus may be the better option for you.

Samsung Galaxy S9 vs. S9 Plus Battery Life Comparison

Due to its bigger size, the Samsung Galaxy S9 Plus’s battery has a larger capacity in comparison to the Galaxy S9. It comes with a 3,500 mAh battery, while the Galaxy S9 comes with a 3,000 mAh battery. Talk time for the Galaxy S9 is rated at roughly up to 31 hours with video playback up to 17 hours, while the battery of the Galaxy S9+ comes in at up to 35 hours talk time and up to 20 hours video playback. Both models come with a built-in Qi Powermat for wireless charging.

It might be reasonable to assume that having a larger display means that the battery loses power more quickly, however that isn’t the case with the Samsung Galaxy S9 Plus. This edition can last significantly longer than the Galaxy S9, and you can easily make it through the day without charging or needing to use a portable power bank.
