If my battery percentage is that low, then I would stop whatever I am doing and hook it up to the charger. NEVER let the battery percentage go below 20%. That is the danger zone. Try to conserve electricity by reducing the brightness and going into dark mode and making sure that the brightness is kept that low. The reason is, going to 0% and then recharging back up is not good/healthy for the phone's battery in the long run. Sure, you can always buy a new phone battery, but why buy new all the time when you can take precautions today and make sure that the existing battery can go for as long as possible?
