battery dies.
The ZenBook Flip 13’s 8.5-hour battery
life may make you yawn, but remember
this is with a 4K screen. If you look at the
battery chart, laptops with higher-
resolution screens tend to cluster at the
bottom, while those at the top are all
1920x1080 (FHD) panels.
Asus compensates for the power
consumption of that 4K panel with a larger
battery. Typical laptops this size give you a
battery in the 50-Watt-hour range, but Asus
correctly ups the battery capacity to 67
Watt-hours. That larger battery tips the
ZenBook Flip 13’s life from what could have
been mediocre to decent, for a laptop with
a 4K screen.
BOTTOM LINE
The Asus ZenBook Flip 13 leaves us with
three strong impressions. The first two
are the spectacular OLED panel (which
we’ve already gushed over) and the CPU.
Intel’s 11th-gen chips are impressive,
even if they don’t knock out AMD’s Ryzen
- Multi-core performance could be
better, but the single-core performance
that represents most of what we’d do
on a smaller laptop is strong. Throw in
leading graphics performance and you
can’t lose.
The third thing is the headphone port.
You may not think it’s a big deal, but many
laptop makers are watching very carefully to

common tasks.
Moving on from CPU-focused tasks, we
use 3DMark Sky Diver to look at graphics
performance. The gaming chops of the
ZenBook Flip 13 may surprise you. Despite
being thinner, lighter and smaller than the
Lenovo Slim 7, it’s basically on a par with
this larger laptop when set to its
performance mode.
The last test is perhaps the most
important one, and that’s battery life. For
that, we put the laptop into Airplane mode,
with the display brightness set to 250 to 260
nits. Then we loop a 4K video file until the
