Fast charge allows you to recharge the phone battery for a minimum period of time. Many gadget manufacturers are developing their own storage capacity enhancement systems in order not to buy a license from a similar technology from Qualcomm.
Apple is no exception to this rule, therefore, to recharge the Iphone in accelerated mode, phones from this manufacturer are equipped with an original system for restoring battery capacity.

What is fast charging in iPhone smartphones
Fast charging in smartphones iPhone, like wireless charging, is one of the latest technical developments. This function allows you to apply increased current to the battery. At the same time, the process of restoring capacity practically does not violate the battery’s performance, even with daily use.
The safety of this technology is due to microprocessor control of the capacity recovery process. The smartphone or tablet charges at an accelerated rate only up to 50 percent, then the device goes into normal charging mode. In addition, the charging system is equipped with high-quality cable, which easily tolerates increased load.
Then the power gradually decreases until the battery reaches a charge of 80%. At the next stage, the battery is charged with minimum current, that is, such a device works like a regular network adapter, not equipped with the Quick Charge function.
Which IPhone Phones Support Fast Charging
Apple began to use fast charging technology only in 2017, but even for this short period a large number of iPhone models were equipped with this function. Currently, the following devices support this technology:
- iPhone 8
- iPhone 8 Plus.
- iPhone X.
- iPhone XS
- iPhone XS Max.
- iPhone XR.
All of these models allow you to use charging power up to 18 watts, which is almost 2 times higher than the power of a standard device to restore battery capacity.
How to enable the fast charge function in iPhone
Depending on the iPhone model, quick recharging can be connected automatically or activated in the settings of the mobile device. In the first case, just connect the adapter and the function of accelerated battery recovery will be activated.
If the phone comes with only a regular charger, you will need to purchase a separate original cord and iPhone charger that supports the function of accelerated charge recovery. In addition, you will need to activate this function as follows:
- Go to the "Settings" section.
- Select the icon with the battery image.
- Go to battery settings by clicking on the icon located in the upper right corner.
- Set the quick charge function to the ON position.
After fast charging is turned on, the device will charge much faster, provided that you use an adapter that supports the quick charge function.
How to disable fast charging on iPhone
In order to disable this feature, you must also go to the settings of the mobile device. This is done in the following sequence:
- Go to the settings of the mobile device.
- Go to the battery settings section.
- Find the quick charge function.
- Set the virtual switch to the off position
If you turn off this function, then when the adapter is connected, the process of restoring the battery capacity will be carried out in normal mode.
Is fast charging harmful for the phone
Before introducing the new technology in the production of smartphones, Apple conducted rigorous testing of its own design. As a result of such tests, it was found that with the correct use of the quick charge recovery function, this technology is completely safe for both a smartphone and a charger.
It should be noted that without fear, you can use the phone in accelerated charge recovery mode only if certified cable and adapter have been purchased. The use of cheap Chinese fakes can lead to overheating of the port and cable, as well as to critical heating of the battery, which, at a certain temperature, can explode.
A significant reduction in battery life, when using this function, can contribute to the incorrect use of this technology by the user. Lithium-ion batteries have a long shelf life, but they do not last forever. On average, these batteries are rated for 500 charge / discharge cycles. If the smartphone is charged, on average, every other day, the battery will last at least 3 years.
Unfortunately, many iPhone owners abuse the fast charge feature. For example, they charge the device for up to 50% for half an hour and then disconnect the adapter. Such undercharging will be counted as a full cycle, and if in this way to restore the battery charge several times a day, then the battery will not work for 1 year.
Using a smartphone while charging is also undesirable, because part of the energy will be spent on providing electricity to the screen, processor and other components of the device. Full recovery of the capacity, using the technology of accelerated capacity recovery, takes no more than 2 hours, so you can always find the time to leave the device charging without using it at the same time.
