When using expansion devices for external access, such as HDMI converters, it's essential to understand how they impact your device’s power consumption. Though dongles may appear trivial, they can accelerate power loss far more than anticipated—especially when poorly configured. To improve energy efficiency while using dongles, begin by prioritizing certified products. Seek out devices with low power ratings like Energy Star. Steer clear of cheap, اکتیو باکس unbranded dongles that frequently lack proper power regulation.

Always remove adapters when idle. Even in idle mode, many dongles consume trickle energy, and this silent power suck can shorten runtime—especially on tablets operating on limited charge. If your device offers several connection points, use a active expansion base for external storage 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 enhance power efficiency. On 11, navigate to Power Management tab 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 continuous data streaming unless absolutely necessary. For instance, a USB Wi-Fi adapter that constantly scans for networks can consume 2–3x more power. Position the dongle to ensure strong signal reception—this cuts energy waste. If needed, use a shielded extension to move it away from obstructions like wireless routers.

Finally, track your device’s power usage using native diagnostics. Windows offers Battery Saver report, while Apple Silicon Macs provides Energy Impact. These tools identify top power consumers. If a dongle dominates power usage, swap for a low-power alternative like integrated Bluetooth that uses optimized hardware.

By making minor adjustments and being conscious of timing, you can significantly extend battery life without compromising performance.
