ESP32 Battery Life Q&A – Save Power with These Code Examples!

Follow-Up Video: ► Save Battery Life on Your ESP32 - How to Make a custom PCB: [   • Save Battery Life on Your ESP32 - How to M...  ] (Based on your awesome comments and questions!) You asked how to save even MORE battery on your ESP32, and I listened! In this video, we dive into the advanced power-saving tricks you requested in the comments of my last deep sleep tutorial [   • Save Battery Life on Your ESP32 – Deep Sle...  ]. We go beyond the basics and explore real-world code examples to give your battery-powered projects superpowers. We'll cover how to wake up your ESP32 with an external button, use light sleep to pause without rebooting, manually control CPU speed (and learn the critical difference between power and energy!), and disable the power-hungry Wi-Fi radio.
