    Hi and welcome to iMore

    You need to calibrate your battery by fully depleting it till your device turns off and then plug in the charger and let it fully charge untouched until it's been at 100% for at least 15 minutes

    As for the power off at night issue. It advices to plug your device in at night and keep it topped off for maximum battery life. It your device keeps you awake you can schedule Do Not Disturb
