37 day uptime

My PostmarketOS Edition phone has been on and sitting idle for over 37 days. I would periodically login over ssh and do updates. It was fine and stable until today when the modem disappeared, a reboot and it is back to normal. While it was mostly idle it was running Monitorix and recording statistics. It was also sending a hourly/daily email with a summary of stats. Although this is a PostmarketOS Community Edition phone, it is running Arch Linux ARM, with the RAM speed set to 492MHz. The reason for running the RAM at a lower speed is explained here . Some graphs from Monitorix showing the last 30 days. Uptime Memory Usage. This is a 3GB model. Chrony Stats I added monitoring of some PinePhone specific stats using the gensens module. Temperature readings from the CPU/GPU. CPU frequency of the 4 cores. Battery charge level.
