This post discusses the installation of postmarketOS on Android devices to create a Linux-based environment that can run Docker, potentially transforming the phone into a home server. Users point out the challenges of running a server on an Android phone due to aggressive background app management by Android and the impact on battery life from continuous use as a server. There are opportunities for leveraging inexpensive devices like Motorola G series phones for such setups due to features like battery charge limiting, decent specs, and built-in network capabilities. Users express mixed opinions on this approach, questioning the practicality versus the alternative of using dedicated mini-PCs or other hardware solutions. Some comments indicate a growing interest in hosting services on phones but raise concerns regarding the technology and battery longevity.
