I don’t think jailbreaking will change a lot power consumption. Maybe even the opposite, as you may break service that aims to decrease consumption.
On my stock android (cross call core X4), in airplane and battery saver mode, it can last for a week. I use it when trekking and just use GPS with osmand from time to time.
Just be sure to disable all shitty apps (WhatsApp, gmail, etc…)
