The charging speed also plays a crucial role in determining the impact of reverse charging on battery life. Faster charging speeds, like Quick Charge or VOOC, can increase power consumption, resulting in a higher drain on the battery. This means that devices that support rapid charging may be more affected by reverse charging than those that use slower charging speeds.
On the other hand, devices with slower charging speeds, like Qi-enabled devices, may experience less of an impact on battery life due to the lower power consumption.
Battery Health and Reverse Charging
Another important factor to consider is the impact of reverse charging on battery health. Lithium-ion batteries, which are commonly used in smartphones, have a limited lifespan and can degrade over time.
Battery Cycle Life
Reverse charging can affect the battery cycle life, which is the number of charge-discharge cycles a battery can handle before its capacity starts to degrade. A higher number of charge cycles can lead to a reduction in battery capacity, affecting overall battery life.
A study by the Battery University found that lithium-ion batteries can handle around 300-500 charge cycles before their capacity starts to degrade. Reverse charging can increase the number of charge cycles, potentially reducing the overall battery life.
Battery Calibration and Reverse Charging
Battery calibration is another crucial aspect to consider when discussing the impact of reverse charging on battery life. Calibration is the process of maintaining the battery’s state of charge within a specific range to ensure accurate battery level readings.
Reverse charging can disrupt the battery calibration process, leading to inaccurate battery readings and potentially affecting the overall battery health. This can result in reduced battery life and performance issues.

What is Reverse Charging?
Reverse charging is a technology that allows a device, typically a smartphone, to act as a power source and charge other devices. This is done by reversing the flow of electrical current, effectively turning the device into a power bank. Reverse charging is also known as wireless power sharing or reverse wireless charging.
The technology uses the same Qi wireless charging standard that is used to charge devices wirelessly. However, instead of receiving power, the device acts as a transmitter, sending power to other devices. This allows you to charge your earbuds, smartwatch, or other devices on the go, without the need for a separate power bank or cable.
How Does Reverse Charging Affect Battery Life?
Reverse charging can affect battery life in several ways. Firstly, it can reduce the overall battery capacity, as the device is using its own battery power to charge other devices.
