How many batteries can IoT really handle?
Most conversations about sustainability in tech focus on networks, hardware or energy use. But the real elephant in the room might be the tiny battery powering your sensor. In this article, I dive into how often these batteries need replacing, why energy harvesting still isn’t the standard, and what second-life lithium cells could mean for the future of connected devices. If we want smarter systems, maybe we need to start designing with energy in mind.
