When using expansion devices for external access, such as USB Wi-Fi adapters, it's essential to understand how they impact energy efficiency. Though extenders may appear small, they can accelerate power loss far more than anticipated—especially when left plugged in. To optimize power management while using dongles, begin by prioritizing certified products. Seek out devices with low power ratings like IEEE 802.11u-compliant. Steer clear of no-name adapters that frequently lack proper power regulation.

Always disconnect peripherals when not in use. Even in idle mode, many dongles consume trickle energy, and this gradual loss can shorten runtime—especially on ultrabooks operating on mobile energy. If your device offers several connection points, use a powered USB hub for high-drain devices like USB audio interfaces, so your device core isn’t forced to compensate for inefficiency.

Keep your dongle’s firmware + drivers up-to-date. Manufacturers often release optimizations that reduce idle draw. On Windows, navigate to Device Manager and select the option to Allow the computer to turn off this device to save power. On macOS Sonoma, visit System Preferences and adjust energy saver to curtail unnecessary connectivity.

Avoid using dongles that demand sustained high throughput unless absolutely necessary. For instance, a USB Wi-Fi adapter that repeatedly reconnects can drain battery rapidly. Position the dongle to ensure strong signal reception—this lowers transmission power. If needed, use a longer adapter cable to relocate the dongle like metal surfaces.

Finally, track your device’s power usage using system utilities. Windows offers Battery Saver report, while Apple Silicon Macs provides Energy Impact. These tools show which peripherals are draining fastest. If a dongle appears as a major drain, اکتیو باکس switch to a built-in solution like native Wi-Fi that eliminates external draw.

By making minor adjustments and being aware of placement, you can dramatically improve runtime without compromising performance.
