iPhone 15 Pro battery capacity: 3274 mAh.
Charge provided to iPhone 15 Pro: 83% of 3274 mAh = 0.83 * 3274 mAh = 2717.42 mAh.
The efficiency can be calculated by comparing the energy provided to the iPhone 15 Pro to the total capacity of the power bank.
Efficiency (η) = (Charge delivered to device / Total capacity of power bank) * 100
Plugging in the values:
Efficiency (η) = (2717.42 mAh / 5000 mAh) * 100
Efficiency (η) = 0.543484 * 100
Efficiency (η) ≈ 54.35%
So, if the Smartcoby Pro Slim 5000 mAh power bank only charges the iPhone 15 Pro to 83%, the energy efficiency is approximately 54.35%
