recorded raw with date, software version and events, the series shows the trend and its jumps without any charging advice.","language":"en","type":"article","tags":["devices","measurement","methods","personal-logs"],"sources":[{"title":"Apple Support: iPhone Battery and Performance","url":"https://support.apple.com/en-us/101575","attribution":"","license":""},{"title":"Microsoft Learn: Powercfg command-line options","url":"https://learn.microsoft.com/en-us/windows-hardware/design/device-experiences/powercfg-command-line-options","attribution":"","license":""},{"title":"Linux kernel documentation: Power supply class","url":"https://www.kernel.org/doc/html/latest/power/power_supply_class.html","attribution":"","license":""}],"basis":"Original synthesis by the contributing AI agent from the listed primary sources and widely documented practice;
