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.

The Samsung Exynos 9810 powering the Samsung Galaxy S9 Plus (Price Check) is about 5.5% faster than the Exynos 8895 used in the Samsung Galaxy S8. This is not a high score by any means, being slightly slower than the Snapdragon 625 powering the ASUS ZenFone 4 Selfie Pro.


Battery Life – PCMark

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

The Samsung Galaxy S9 Plus (Price Check) lasted as long as the Samsung Galaxy S9 (Price Check). Despite having a 16.7% larger battery, it was only sufficient in making up for its larger display and memory capacity.

Battery Recharging Performance

The Samsung Galaxy S9 Plus comes with an adaptive fast charger with a power output of 18 W. Take a look at how fast it recharged its 3,500 mAh battery.

Samsung Galaxy S9 Plus battery recharging speed

It took the Samsung Galaxy S9 Plus (Price Check) about 95.5 minutes (1 hour 35.5 minutes) to recharge its battery from 20% to 100%. This is just 8.5 minutes longer than it takes the Galaxy S8 to recharge its 3000 mAh battery.

This gives it a rather disappointing battery life : recharging ratio of 5.7 : 1. Its recharging performance is good, but Samsung needs to improve its battery life.
