Asus Eee Pad Transformer Prime, Tegra 3 Unleashed

Battery Life Testing

In an attempt to quantitatively measure the Transformer Prime's battery life in a controlled benchmark environment, we ran a test in which we set up a webpage with a mix of graphics and text. The page automatically refreshes every three minutes.  This is a simple baseline test that measures up time with web browsing.  Due to time constraints, we were only able to test one performance mode with the tablet, so we chose its Balanced mode for our measurements.  In the future we hope to do more testing in other power modes as well with the Transformer Prime.

Untethered Up-Time Measurements

For this test, we set the Prime's display to 50% brightness, which is still plenty bright and easy on the eyes. Again, this test was setup in the Balanced performance mode for the tablet.  In Power Saver mode, which will offer plenty of performance for simple web browsing, you could expect longer up time.

Not the most impressive result for the Prime here but again, with Power Saver mode kicked in, our results could be dramatically different.  Also, remember that the Tegra 3 SoC incorporates a quad-core CPU, so twice as many cores are at play here, though power gating on those cores probably significantly reduces consumption.

We'll have to return to our testing in power consumption and update our results with both Power Saver mode enabled and with the keyboard dock snapped in for a bit more life as well.
