Work Performance – PCMark

We tested the Samsung Galaxy S9’s performance using PCMark, which simulates work applications like web browing, playing video, writing text and editing photos.

When it comes to work applications, the Samsung Exynos 9810 powering the Samsung Galaxy S9 (Price Check) is about 6% faster than the Exynos 8895 used in the Samsung Galaxy S8. This puts it at par with the Snapdragon 625 powering the ASUS ZenFone 4 Selfie Pro.


Battery Life – PCMark

We then tested the Galaxy S9’s battery performance using PCMark. It basically ran the PCMark work tests until its battery capacity dropped to 20%.

The Samsung Galaxy S9 (Price Check) lasted just over 9 hours in our battery test. That is almost 1.5 hours shorter than the Samsung Galaxy S8, and over 3 hours shorter than the Samsung Galaxy A8 2018. It only managed to beat the ASUS ZenFone 4 Selfie Pro by 25 minutes

Note : All four smartphones compared here have a 3,000 mAh battery.

Battery Recharging Performance

The Samsung Galaxy S9 comes with an adaptive fast charger with a power output of 18 W. Take a look at how fast it recharged its 3,000 mAh battery.

Samsung Galaxy S9 battery recharging speed

It took the Samsung Galaxy S9 (Price Check) about 108 minutes (1 hour 48 minutes) to recharge its battery from 20% to 100%. This is 21 minutes longer than it takes the Galaxy S8 to recharge the same battery capacity.

This gives it a battery life : recharging ratio of 5 : 1 – a rather disappointing performance.

Note : Our Samsung Galaxy S9 sample did not come with its charger. We used the Samsung Galaxy S8‘s charger instead. We will retest when we receive the official Galaxy S9 charger.
