Battery Performance

One of the attractive features of the Core M platform is the promise of increased battery life. In fact, Intel has stated that Core M systems should see a battery life that is up to 1.7 hours longer than the prior generation.

Asus claims the T300 Chi will last for up to 8 hours on battery power. Of course, battery life will depend on how much you require of the system throughout the day.

Battery Eater Pro and Web Browsing Tests
Battery Life Testing

In an attempt to quantitatively measure the T300 Chi’s battery life in a controlled benchmark environment, we ran two tests to get a sense of how long the system will last under light and heavy use. Our web browsing test is a light-use scenario in which it refreshes a webpage over a Wi-Fi connection until the battery is exhausted. For this test, we set the T300 Chi’s display to 50% brightness and connected to the web via a wireless network.

The Battery Eater Pro test gives the laptop a much heavier workload to simulate the kind of stress you might put on the machine with multiple resources engaged including CPU, GPU, memory and hard drive.

The T300 Chi performed well in the strenuous Battery Eater Pro test, lasting for just over three hours and coming in fifth place in our chart.

We expect systems to last longer in our custom web browsing test than they do in the Battery Eater Pro test. Indeed, the T300 Chi lasted longer in this test, making it to five hours of runtime before shutting down. If you look at our comparison chart however, the T300 Chi is at the bottom of the chart. Although many of these comparison systems have larger batteries, we were a bit disappointed by the T300 Chi’s longevity in this test.

Real-world battery results are also mixed depending on how you use the system. If you don’t need the keyboard dock, you may want to consider turning off Bluetooth in an attempt to save even more battery power.
