Microsoft has always claimed that the Edge is more user-friendly than a laptop battery than chrome. Today, the company has brought its experience in energy management at the Windows level through a patch to the Chromium project.

Last year, before Microsoft abandoned its own navigation engine and replaced it with chrome, Edge, which beats chrome, showed in a video streaming test on Surface Books with Windows 10.

Microsoft introduces an experimental feature in Chrome to improve battery life:

Microsoft engineers have identified the problem behind battery consumption as the excessive caching of data that Chromium browsers display when processing media. According to a Chromium Commit, “holding the hard disk during this process generally increases power consumption and can also prevent the integration of some less efficient modes into the operating system. As media consumption is a high consumption scenario, this additional energy consumption has a negative impact on the battery life.” Data caching means that the hard disk is active and therefore consumes a lot of energy. Any activity that does this will have a negative impact on the life of your battery.

July 2024 Update:

You can now prevent PC problems by using this tool, such as protecting you against file loss and malware. Additionally it is a great way to optimize your computer for maximum performance. The program fixes common errors that might occur on Windows systems with ease - no need for hours of troubleshooting when you have the perfect solution at your fingertips:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.


The patch proposed by Microsoft includes data caching prevention, which can affect the speed at which you can access certain types of media, as well as detection of when a power source is connected, so that caching can continue normally when battery use is not a problem.

Since Microsoft engineers created the “Caching” flag, which allows correction, it has taken less than a week for Chrome engineers to implement it themselves in Google Chrome Canary Build. This means that there is a good chance that it will soon be in the regular version of Google Chrome, and that we can all save a little energy the next time we launch the Google web browser. Thanks to Microsoft, we promise to try Edge again soon.

Microsoft is in the process of achieving the following objectives:

  • Improve the life of the device’s battery by reducing power consumption during playback of the media.
  • Minimize the negative impact on common scenarios that may depend on hard disk caching, in particular by optimizing search time when the user rewinds or fast-forwards a few seconds.


Microsoft conducted local tests by streaming unencrypted 1080p streaming multimedia content on a laptop computer while it was disconnected from the power grid, and the first results look promising.

The implemented solution reduced system disk writing activity by 309KB/sec.

The feature seems to work well, but only time will tell if it will find its way on Microsoft chrome-based browsers or if it will just remain a test.
