A full charge cycle means charging the battery to 100 percent and then letting it run all the way down until the iPhone shuts off. If you do this once a month, you won't have to worry about using partial charges during the rest of the month.
How full should you charge your iPhone?
Do not fully charge or fully discharge your device's battery — charge it to around 50%. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge.
How do I charge my iPhone to 80 percent?
Optimize iPhone battery charging
This setting uses machine learning to understand your daily charging routine, then waits to finish charging past 80% until you need it. Go to Settings > Battery, then tap Battery Health. Turn on Optimized Battery Charging.
