One of the most requested features on an Apple iPhone is the fast charging capability. None of the iPhones until 2017 November had the capability for the fast charging (which takes less time compared to the normal charging) and finally, the latest Apple iPhone X, Apple iPhone 8 Plus, and the Apple iPhone 8 does feature fast charging capability and to use one has to follow the below mentioned steps. Apple even went a step further to include wireless charging capability on all the models, that to based on the Qi standards.
All three iPhones does offer fast charging out of the box and there are no settings to enable or disable the same. However, the retail package included power brick is rated at an output of 5 volts and 1 amps, and it takes more than 2 and a half hours to completely charge the iPhone on an idle condition, if you are using the device while charging, then it taken an extra 60 minutes to 90 minutes depending on the intensity of the task and the power consumed to do the same.
However, if we look at the Apple official listing all three smartphones do support fast charging (printed finely, saying that on lab condition). Don’t worry about damaging your battery using any third party accessories, all you need is an iPad charge. The Apple iPad charger, that comes with 29 Watt output, compared to the 5 watts on the retail package included the charge. The charger retails for $49. As this power brick comes with a USB type C port, so one has to shell out at least $25 to get a new cable as well. So, for $74, your iPhone can charge up to 50 percent in just 30 minutes. So, if you need to use a feature on your costliest iPhone, then you need to pay the royalty for the makers by making newer hardware purchases.
