What is "Power Save Mode" in IntelliJ IDEA and other Jetbrains IDEs?

What is Powersave mode?

Let me introduce you to the Android Power Save Mode. Power Saving Mode monitors your battery and, upon reaching a percentage, will shut off certain features to keep the battery from draining too quickly.

Does IntelliJ include PhpStorm?

All of the functionality of our lightweight IDEs can be found within IntelliJ IDEA (you need to install the corresponding plug-ins from the repository). It includes support for all technologies developed for our more specific products such as Web/PhpStorm, RubyMine and PyCharm.


It's a setting to stop the IDE from automatically performing the full range of battery-hungry code inspections in the background as you type.

You should find that with powersave turned on, syntax errors will still get highlighted, but iffy code constructs e.g. missing docblocks, assignment inside conditional statements etc will not (assuming you have those inspections enabled). This means that you can save battery power when using your laptop and choose to run the inspections only occasionally by turning power save mode off for a minute or two, or using Code->Inspect code... to see what needs attention.

See Settings->Inspections to find out whether you can live without the specific inspections, which will depend on what language you are using. You can choose to run them individually on demand if you like using Code->Run inspection by name... if there are specific ones you need. More info here.

Naturally, this also applies to RubyMine, PHPStorm, PyCharm, WebStorm & AppCode as well.
