How much power does an iPhone charger use?
For a long time, the standard charging solution that Apple offered for iPhone users was the 5V/1A power adapter, which meant that the maximum output from the charger to a connected device was just 5W. So even though some iPhones were capable of handling 12W (5V/2.4A) or higher, they could only get 5W at a time, which inevitably prolonged the time to recharge the phone.
How to calculate wattage of iPhone charger?
First, make sure the power adapter supports the USB PD standard , the standard that the iPhone follows. Second, check the wattage of the power adapter. The total wattage may not be printed on the device or box of some chargers. But don’t worry, as long as you can find the voltage and amperage, you can do some quick math to calculate the total wattage: Amperage X Voltage=Wattage. A charger of 5V/3A can deliver total 15 wattages, but if you have an iPhone 11, you would need a more powerful charger to get the most out of it’s 18W fast charging.
What voltage is a USB charger?
A USB PD charger or power adapter can deliver a range of voltages, from 5V, 9V, 12V, 15V, 19V all the way up to 20V, with each voltage being named PDO1, PDO2, PDO3 and so on. The PDOs differ between different chargers. Take the Apple 29W PD charger as an example. It can only deliver two types of voltage: 5V and 14.5V, so the PDO1 of this charger is 5V, and PDO2 is 14.5V. Before the charger delivers power to the device, they negotiate and find the voltage that both devices support. Say an iPhone supports maximum 10V input, if you use the Apple 29W PD power adapter to charge up this iPhone, then the power adapter will only deliver power at PDO1 5V.

Why does my iPhone stop charging at 80%?
In fact, the temperature monitoring module inside the iPhone will control the input power based on the real-time temperature of the battery. When it’s too hot, the iPhone module will lower the power delivery rate to make sure it’s under 50 degrees Celsius. Likewise, the iPhone will gradually reduce the input power when the battery reaches 50%, to maximize the lifespan of the battery. When it reaches around 80%, charging becomes significantly slower. This is precisely why some iPhone users think that their iPhones stop charging at 80%. You can learn more about this issue from our previous blog: Why Your iPhone Stops Charging At 80% (& How To Fix It)
