Power Saving on Rasbian

Power Saving on Raspbian

Raspbian allows you to optimize settings for better power efficiency. This guide focuses on methods to reduce energy consumption, making your Raspberry Pi more efficient for battery-powered or always-on projects.

Check Current CPU Frequency

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Set CPU Governor to 'powersave'

sudo cpufreq-set -g powersave

Set Maximum CPU Frequency

sudo cpufreq-set -u 600000

Disable HDMI to Save Power

sudo /usr/bin/tvservice -o

Turn Off Unused USB Devices

echo '1-1' | sudo tee /sys/bus/usb/drivers/usb/unbind

Reduce GPU Memory Allocation

sudo nano /boot/config.txt
# Add or modify:
gpu_mem=16

Applying these settings can significantly reduce power consumption, ideal for headless setups or long-term operations.

Happy optimizing your Raspberry Pi! ⚡
