How to Change "JavaScript Timer Frequency" Power Option Setting for IE9 and IE10

information   Information
This tutorial will show you how to change the setting for the JavaScript Timer Frequency power option for IE9 and IE10 in Windows 7 and Windows 8.

There have been a very few reports of some users having possible increased battery drain or sleep issues with the Maximum and Power Saving settings enabled, respectively. These may or may not be mis-identified issues, but you may want to test out the different settings from the default if they apply to you.


information   Information
IE9 and IE10 has a power setting in Windows 7 and Windows 8 Power Options, called JavaScript Timer Frequency. This is tied in with the IE9 and IE10 javaScript engine.

The apparent reasoning behind the two available settings of this new Power Option are basically summed up by this line in the IEBlog:

An optimized experience on platforms from multi-core desktops to netbooks and mobile devices. User code in an HTML and JavaScript application is mostly single-threaded, but on today’s modern multi-core machines, browsers should find ways to use other cores intelligently to improve performance. At the same time, browsers must also run well on netbooks and low-power machines.


While on the Power Saving option, this will slow down the execution of JavaScript in IE9 and IE10 which will also lower power consumption. This is the automatic setting on laptops, netbooks.


Note   Note
The two settings are as follows:

Maximum Performance: (default on desktops/plugged in devices) for optimal JavaScript performance in IE9 when power consumption or battery life is not critical or required.

Maximum Power Savings: (default on laptops, etc) ideal when power consumption and battery life is important, such as a laptop, netbook, etc.


Reducing JavaScript Timer Frequency can slow down the java script animations and execution in Internet Explorer which in turn can save battery life. If you want faster browsing in Internet Explorer, then you might want to change this setting to "maximum performance" in power settings. Slower performance is a compromise to save battery life. By default, when using a PC on battery, Internet Explorer will automatically switch to "maximum power savings" for JavaScript Timer Frequency.




Here's How:


1. Open the Control Panel (icons view), and click/tap on the Power Options icon.

4. Pick either the Maximum Performance, or Maximum Power Savings setting that applies if you wish to change it from the default setting, and click/tap on OK.

Hello Harvey,

It's basically just to either have maximum browser performance of any running java scripts in Internet Explorer, or to save battery life by reducing performance.

Ohh ok lol. Is it true Java has horrible security capabilities? I read somewhere that Java tremendously blows for lack of a better term.

Yeah, I wouldn't recommend using anything with Java if you can help it.

So it's safe to say the scripts that IE uses is just as horrible?
