Red Hat has released Tuned 2.28, introducing default power-saving profiles for laptops running Fedora to curb unnecessary energy consumption. According to development documentation published by Red Hat engineers, the latest release alters how the system manages Wi-Fi power states out of the box, shifting away from aggressive performance defaults that drain laptop batteries quickly.
How Tuned 2.28 Modifies Wi-Fi Power Savings
According to Phoronix reporting on the release, Tuned 2.28 applies active power management rules to wireless interfaces by default on supported laptop profiles. Previous versions left Wi-Fi power-saving features disabled or set to minimal management to prevent rare latency spikes. The updated package enables modern power-saving states natively, reducing idle power draw without requiring manual configuration from users.
System administrators and mobile users can verify their active profile using the standard command-line utility. Running tuned-adm active displays the current profile, while tuned-adm profile laptop switches systems manually if the automatic detection fails to engage the appropriate power-saving parameters.
Performance Impact and Hardware Compatibility
While aggressive power management can occasionally introduce minor latency increases during network handshakes, Red Hat’s updated profiles balance responsiveness with battery longevity. According to upstream release notes, the changes target modern Intel and AMD wireless chipsets commonly found in contemporary Linux laptops.
Users running Fedora can expect the update to arrive through standard system repositories as maintainers push Tuned 2.28 into stable channels. Desktop users with wired connections or uninterruptible power supplies see little direct change, as the profile logic specifically targets battery-powered mobile hardware.
