Acer Aspire R 13 Convertible 2-in-1 Review
Battery Performance
Acer claims the Aspire R 13 will last for up to 9 hours on battery power. Of course, battery life will depend on how much you require of the system throughout the day.

In an attempt to quantitatively measure the R 13’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 R 13’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 R 13 didn’t perform as well as we had hoped in the strenuous Battery Eater Pro test, lasting for just over 2.5 hours and coming in near the middle of 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 R 13 lasted longer in this test, making it through 5 hours and 43 minutes of web browsing before shutting down. In many cases, there is a more dramatic difference between the longevity of a system in these two tests. If you look at our comparison chart, you’ll see that the R 13 comes in near the bottom in the Web Browsing test. Of course, real-world battery results will be mixed depending on how you use the system.
