Systems compared: Acer Aspire* S7-392 with Intel® Core™ i7-4500U vs. an Acer Aspire* S7-391 with a 3rd generation Intel® Core™ i7-3517U processor.
4 Workload: MP4 1080p 20Mbps h.264 High Profile L4.0 144MB 60 second clip. Method: In the device settings, disable all radios (Bluetooth*, 3G, GPS, etc.) except Wi-Fi*. Associate Wi-Fi* to an 802.11n access point. Set up the system to ~150 nits screen brightness using a full screen white background. Turn OFF the adaptive brightness setting under Power Options in Control Panel. Set “Dim the display” to never on both battery and AC. Set “Put the computer to sleep” to never on both battery and AC. Wait 15 minutes after boot. Launch the default Windows* 8 Style UI video player and load the MP4 1080p workload video (1080p ElephantsDream_H264_1080p_10M.mp4 Total Bitrate: 10124kbps). Make sure to start the video playback and disconnect the AC to start the test. Loop the video until battery is exhausted and record the time. Fully charge the system and repeat a total of three runs. Use the median of the three-run battery data. Battery size normalized to 50 WHr.
