Battery & Charger

When it comes to battery, for all I can say is that the ASUS ZenBook Flip S can last you about 5 hours or so on web browsing with some music and social media sites running together while running on semi-better performance. As we saw earlier, the battery itself might look huge – but it’s rather thin. The total volume of the battery is rather small, hence the battery is only rated at 39Wh.

However, ASUS decides to take away control of the power plan from the user. There’s only one power plan available – and that’s Balanced. ASUS then offers a slider on the battery menu itself, asking if you’ll like more performance, or longer battery life.

The slightly altered power plan option can be seen when the AC jack is connected. I find it rather… bizarre that ASUS used the word “best battery life” while plugged in. I’m pretty sure ASUS wants to convey the message where using the “power saving” mode when plugged in means it can charge faster, but they labelled it as “best battery life” instead.

I’m not sure if using such gauge is a good idea. ASUS hid the details and differences between all the modes, but through a simple Cinebench benchmark, it seems like, on Best Battery mode, it scored 224CB and the processor is mostly hovering at about 1.9GHz most of the time. On Best Performance mode, it scored 290C and the clock speed is maintained at 2.9GHz most of the time.

On whatever power plan that it’s on, it doesn’t affect the NVMe SSD’s speed either.

The charger, on the other hand, is a tiny one.

It has a few output wattages – either 65W which is the maximum, or 45W, 27W, or 15W. This power brick design is seen in many other ASUS laptops too – like the ZenBook 3 Deluxe that we saw here.
