Try to avoid overcharging and overdischarge. It is generally recommended to charge the mobile phone when the battery power is only 20-30%, and disconnect the charging when the battery power is 80-90%.

Apple official suggestion
Please do not fully charge or fully discharge, the charging capacity of the equipment should be about 50%. If the equipment is stored when the battery is completely exhausted, the battery may enter a deep discharge state, resulting in inability to charge. On the contrary, if the fully charged equipment is stored for a long time, some battery capacity may be lost, thus shortening the battery life.
Turn off the power of the equipment to avoid using extra batteries. Place the equipment in a cool, non-humid environment with a temperature below 32 C (90 F). If you plan to store the equipment for more than six months, you should charge the equipment to 50% of the power every six months.
