If you have issues with your RTC or lithium-ion battery, you may lose power immediately, and your settings are lost when your camera turns off. In healthy batteries after a few weeks of not turning on your camera will lose its charge. If your camera runs out of energy, your settings will be lost. Your camera uses energy from its lithium-ion battery or in capacitor cameras a small RTC-battery (rechargeable coin battery) to save the time/date/settings in the memory.
