Can Fast Charging Affect Your Device’s Battery Health?

Can Fast charging affect your device's

Fast charging technology is increasingly becoming common and available in a wide range of devices. Almost all of the flagship smartphones today offer some fast charging. The rapid adoption of fast charging is due to the increasing use of smartphones that require people to recharge their phones twice daily. Having lots of benefits, it lets you stay connected and powered up, saving you the valuable time you spend charging your battery. A drained battery can lead to lost productivity, missed opportunity, or frustration. But the impact of fast charging on battery life is debated among smartphone users and experts. It is important to note that modern-day chargers are designed to minimise any harm caused to the battery. However, adopting the best battery charging practices is necessary to ensure longevity. 

This article will help you to understand whether fast charging affects the battery life of your cell phone. 

Fast charging affects battery life is a myth

One of the myths regarding fast charging that affects the battery life of your cellphone is not entirely true. The charging technology has evolved, and modern-day cell phones and chargers are designed to handle the increased heat and regulate the charging process accordingly. Nowadays, Most devices have built-in mechanisms to manage temperature and voltage levels to prevent battery harm. However, it is essential to know that the overall lifespan of the cell phone battery is affected by various other factors, such as usage pattern, temperature, and number of charge cycles.

Upsides of fast Charging

Fast charging has many upsides, making it an essential aspect of modern-day technology. 

Time savings

Fast charging enables you to charge your device significantly within minutes. It allows you to save your precious time by extending the time between the charges for most smartphones.


Fast charging provides us with the convenience of using our device continuously without being interrupted. It allows users with lower-capacity batteries to continue using their favourite apps longer without draining them thoroughly.

Improved Battery life

Some fast charging technologies are designed to optimise the charging process, which helps preserve your battery’s overall lifespan by reducing the time spent charging it.


Fast Charging technology is widely available and can be used with various devices. This benefit makes it a versatile solution for everyone.

Downsides of fast Charging 

Apart from its benefits, fast-charging technology has some downsides as well.


Some fast-charging technologies might not be compatible with all devices. Finding a charger that works with your device can make it difficult.


Fast charge increases the risk of overheating a smartphone, especially for older models with thinner batteries. Overheating can cause battery life to degrade faster.

Preventive measures to avoid battery damage while fast charging 

You need to be aware of the facts while fast charging to ensure its impact on the battery life will be as small as possible.

Use the right charger

Use a genuine or high-quality charger that is specially designed for your device. Using low-quality or counterfeit chargers can lead to overheating, which can cause the battery to degrade faster.

Avoid extreme temperatures 

Avoid fast charging your cell phone in extremely hot or cold environments. Heat can degrade your battery faster than expected, while low temperature can reduce capacity. Avoid leaving or charging your cell phone in the car in direct sunlight. Try to charge your cell phone at room temperature while not in use.

Avoid charging on surfaces that block airflow

Avoid charging on surfaces that block airflow and cause overheating, such as beds, sofas etc. Instead, try charging on flat surfaces like tables or desks.

Minimise using the device during fast charge

Minimise using the device during fast charge as it generates more and more heat. Some users play games while charging without knowing that some power-intensive apps or games put additional strain on the battery.

Try to use fast charging occasionally

Try to use fast charging occasionally when highly needed. Otherwise, charge your device usually to reduce strain on the battery.

Avoid over charging

Even during fast charge, try to avoid overcharging. Unplug your device once it is charged; overcharging can gradually degrade the battery life.

Keep your battery levels between 20 to 80 per cent

The best practice with any Li-ion is to keep your battery levels between 20 to 80 per cent. Try to unplug your battery once it is charged to 80 to 90 per cent by monitoring the charging process. Using a full charge for long-distance trips or when necessary will help to have long-term battery life.

Remove the case

Some cell phone cases block heat and hinder heat dissipation while fast charging. While fast charging, if you notice overheating, try to remove the back cover.

In the end, fast charging is convenient if used occasionally, and with care, fast charging is unlikely to cause harm to cell phone batteries. However, continuing to use fast charging, accompanied by other factors such as frequent usage patterns, number of charging cycles, and temperature, can cause the battery to degrade faster than usual.
