When using USB adapters for external access, such as USB-to-Ethernet dongles, it's essential to understand how they impact battery drainage. Though dongles may appear innocuous, they can reduce run time far more than anticipated—especially when left plugged in. To extend battery life while using dongles, begin by selecting energy-efficient models. Seek out devices with official power certifications like IEEE 802.11u-compliant. Steer clear of no-name adapters that frequently omit power-saving features.

Always remove adapters when not in use. Even in sleep mode, many dongles continue drawing power, and this silent power suck can deplete charge—especially on laptops operating on mobile energy. If your device offers O, use a externally powered dock for external storage like SSDs, so your battery isn’t forced to supply extra power.

Keep your dongle’s firmware up-to-date. Manufacturers often release optimizations that reduce idle draw. On Windows, navigate to Device Manager and select the option to Disable selective suspend. On Ventura, اکتیو باکس visit Battery and tweak power settings to curtail unnecessary connectivity.

Avoid using dongles that demand sustained high throughput unless absolutely necessary. For instance, a network extender that maintains a weak signal can dramatically increase load. Position the dongle to maximize connection quality—this lowers transmission power. If needed, use a shielded extension to position it optimally like metal surfaces.

Finally, track your device’s power usage using native diagnostics. Windows 11 offers Battery Saver report, while Apple Silicon Macs provides Energy Impact. These tools highlight energy-hungry devices. If a dongle consistently ranks high, replace it with a more efficient model like integrated Bluetooth that doesn’t require an adapter.

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