Fast charging is a feature that allows a phone to charge its battery quickly in a short period of time. Fast charging technology utilizes high electric current to push more battery capacity into the phone in a shorter amount of time.
After reaching near full capacity, the charging current gradually decreases to normal levels thanks to the capabilities of the built-in chip in both the charger and the phone.

Does fast charging damage phone batteries?
Many people have misunderstood fast charging technology, believing that it negatively affects battery lifespan and causes quick battery degradation. In reality, that’s not the case, fast charging does not harm the battery or have any negative impact on it.
The majority of modern mobile phone batteries use Lithium-ion (Li-ion) and Lithium-polymer (Li-Po) batteries, as these technologies are difficult to improve. Therefore, developers have focused on finding methods for users to extend the lifespan of their phones. Fast charging is one of the features that have been developed as a result.
Fast charging technology in Android phones
Fast charging can be achieved by increasing either the current or the voltage. To ensure safety, new technologies and techniques aim to balance both factors to optimize charging time and avoid excessive heat generation.
As a result, fast charging charges the phone rapidly up to around 60%, and then the charging time gradually slows down to prevent sudden increases in temperature for both the charger and the phone.
Some of the main fast charging technologies available today include:
Qualcomm Quick Charge
This technology allows the charger to adjust the voltage based on the battery capacity of the device. Its mechanism relies on the integrated chip in both the device and the charger. When the battery capacity is low, it allows a higher current to charge the battery quickly, and then it gradually slows down and stabilizes.
Samsung Adaptive Fast Charging (AFC)
If you’re a Samsung user, you might be familiar with the Adaptive Fast Charging technology. This technology is licensed by Samsung from Qualcomm and is used in devices that don’t utilize Qualcomm Snapdragon chips. Therefore, it shares similarities with Quick Charge technology.
OPPO and OnePlus fast charging technologies
These technologies offer higher current output to charge the battery quickly. They also employ integrated chips in both the device and the charger. The charger is designed to handle higher temperatures to minimize the impact on the device and the battery.
Some considerations when using fast charging
There are many factors that can significantly reduce battery lifespan, and the main factor is exposure to high temperatures. When using the phone for an extended period of time, it tends to get hot. Fast charging technology is advanced and convenient for daily use, but it should not be excessively used.
The efficient use of the battery and its longevity largely depend on how it is used. Here are some tips for using fast charging:
– Reduce screen brightness to a moderate level and turn off Wi-Fi and Bluetooth when not in use. Close background apps as they consume battery power.
– Control and turn off GPS and map-related apps when not needed, and use the charger that comes with the device whenever possible, to ensure maximum safety.
– Charge the phone when the battery is low; avoid using the phone while charging as it poses a risk. Avoid letting the phone completely run out of battery. Avoid overcharging or charging in unstable power sources.
– Avoid overnight charging or charging when the battery is already at 100%.
