I love the Low Power Mode feature. When I'm travelling or in other situations where reliable communication is more important than user experience, I want to always have it enabled, sometimes for days at a time.
However, iOS automatically turns it off after the phone has been charged, requiring me to remember to go in and re-enable it after unplugging my phone. I occasionally forget.
Is there any way (including third-party apps, excluding rooting/jailbreaking) for me to automatically or persistently enable Low Power Mode, aside from the system's automatic behaviour at 20%? A way to leave it on indefinitely, or a way to have it automatically activate earlier (such as at 50%), or a way to activate it based on a schedule?
If there's no user-accessible way to do this yet, I would also be interested in knowing if there are any mechanisms in the operating system (URL schemes, framework APIs) that could potentially be used to control Low Power Mode.
