|
||
|
||
<p>We measured the time it took four identical Surface Book laptops to run fully through their batteries while streaming video. The results were recorded with a camera and a time lapse was made available publicly:</p>

|
||
|
||
<p>The results showed that Microsoft Edge (7:22:07) lasted: </p>
|
||
|
||
<ul>
|
||
<li>70% longer than Google Chrome (4:19:50) </li>
|

<li>43% longer than Mozilla Firefox (5:09:30) </li>
|

<li>17% longer than Opera (6:18:33)</li>

<p>The test was performed on four Surface Books (256GB disk, Core i5, 8GB RAM, integrated graphics) running Windows 10 (10586.318 th2_release). These computers were configured to the following settings, to increase consistency between measures and reduce tasks that may start during the measurement and interfere with the results, while still representing a realistic user setup: </p>
|
||
|
||
<ul>
|
||
<li>Display brightness was set to 75% </li>
|
||
<li>Location was disabled</li>
|
||
<li>Devices were connected to a wireless network</li>
|
||
<li>Defender cache was completely built</li>
|

<li>Defragmentation was temporarily disabled</li>
|

<li>Ambient light sensor was temporarily disabled</li>
|

<li>All queued Ngen complication jobs were completed</li>
|

<li>Windows Update was temporarily disabled</li>
|
||
<li>“New network found” prompts were disabled</li>
|
||
<li>Windows Error Reporting was temporarily disabled</li>
|
||
<li>Queued idle tasks were forced to complete prior to the test</li>
|
||
<li>Windows Defender was running normally and up to date</li>
|
||
<li>Devices were fully changed before being physically unplugged and running on battery for the test</li>
|
||
<li>Volume was turned to 25%</li>
|
||
<li>Battery Saver was off, but enabled automatically when the battery reached 20%. Device was set to lower screen brightness when Windows battery saver started.</li>
|
||
<li>BitLocker was disabled </li>

<p>While plugged in, each respective browser was navigated to Netflix.com and logged into the same account. The show <strong>“Nature: Animal Misfits”</strong> was queued and paused immediately on each browser. Each computer was verified to have brightness set to 75% (with ambient brightness disabled) and volume to 25%. </p>
