Web browser Google Chrome is killing Windows laptop battery

There’s a problem if you use Google Chrome and Microsoft Windows on your laptop.

IT experts say using the two together can drastically affect battery life, and even slow down your computer.

The problem has to do with “system clock tick rate,” something Windows uses internally.

By default, Window’s system clock tick rate wakes up the processor of your computer 64 times per second or once every 15.625 milliseconds.

Chrome resets that tick rate to 1 millisecond.

In Microsoft’s documentation titled ‘Timers, Timer Resolution, and Development of Efficient Code,’ they state the following about setting a 1 ms system timer interval:

“If the system timer interval is decreased to less than the default, including when an application calls timeBeginPeriod with a resolution of 1 ms, the low-power idle states are ineffective at reducing system power consumption and system battery life suffers.

System battery life can be reduced as much as 25 percent, depending on the hardware platform. This is because transitions to and from low-power states incur an energy cost. Therefore, entering and exiting low-power states without spending a minimum amount of time in the low-power states can be more costly than if the system simply remained in the high-power state.”

This issue is not new and was first reported on Google Chromium boards in 2008.

One way to avoid the problem is to use another browser if you’re using a Microsoft Windows computer.

This problem doesn’t happen on Apple’s MacOS or Linux computers as they don’t use the system clock tick rate.
