We would firstly let you know that the battery is able to supply 60%-70% power to other devices. Approximately 30-40% of the battery capacity is unable to be used because of efficiency problems that affect all electronics devices. These include power lost from circuit heat and voltage conversions from the battery, the charging cable and your device. To calculate roughly how many times the battery should charge your device you can use this formula: Capacity of the PowerCore*0.6~0.7) / Capacity of your device = Number of possible charges 26800 mAh * 0.6~0.7 / 3110mAh (iphone 11) = 517% to 603% From your description, this PowerCore+ 26800 mah Portable Charger can charge to your iphone11 five to six times.
