ASUS VivoBook S15 Performance

This ASUS VivoBook S15 (Price Check) laptop is powered by the 7th Generation Intel Core processor, specifically the Intel Core i5-7200U. This is a low-power 15 W dual-core processor with a 3 MB L3 cache, a clock speed of 2.5 GHz and a turbo clock of 3.1 GHz.

Surprisingly for a laptop in this price range, it has a dedicated graphics processor – the NVIDIA GeForce 940MX with 384 stream processors. While it uses the older NVIDIA GM108 GPU,, it is still far more powerful than the Intel HD Graphics 620 integrated graphics, especially when it comes with 2 GB of GDDR5 memory.

What’s rather disappointing for a laptop of this refinement though is the 4 GB of memory it comes with. Granted, it’s fast DDR4-2400 (Hynix HMA851S6AFR6N-UH) memory, but it is still just 4 GB of memory. It should have come with 8 GB of memory.


ASUS VivoBook S15 Storage

ASUS offers a variety of solid state and hard disk drive storage options. You can also opt for SSD-only storage, or HDD-only storage. If you choose to use only an SSD, you can reduce the weight of the VivoBook S15 to just 1.5 kg.

Our model came with both – a small 128 GB Toshiba THNSNK128GVN8 M.2 SSD, as well as a large 1 TB Seagate ST1000LM035 hard disk drive. This combination offers fast boot-up with a large storage capacity, at a low cost.

  • Seagate ST1000LM035 hard disk drive

That said, we would recommend that you try to get at least a 256 GB SSD. With Windows 10 Home installed, there is only 93 GB of space left for you to use – hardly enough to install more than a few applications and games.

The ability to install two drives cannot be understated. It is possible to configure the VivoBook S15 with a 512 GB SSD together with a 2 TB Seagate hard disk drive, giving you a total storage capacity of 2.5 TB!

ASUS VivoBook S15 Battery

The ASUS VivoBook S15 (Price Check) has an internal 3-cell battery with a capacity of 42 WHrs. Instead of the usual lithium-ion cylinder batteries though, it uses the newer lithium-polymer battery technology. This allows for a slimmer form factor, as well as a 3X longer lifespan.

They also implemented the new ASUS Battery Health Charging Technology to prolong its lifespan and decrease the battery expansion rate. Finally, they added fast charging capability, allowing the VivoBook S15 to recharge its battery to 60% in just 49 minutes.

In our battery life tests running YouTube videos on the VivoBook S15 with the display brightness set to 40%, it lasted just over 4.5 hours. In our real world usage tests, we were able to work on it for about 5.5 hours before the battery capacity dropped to 10%.
