does fast charging actually ruin your smartphone battery?


Gone are the days of waiting hours for your smartphone to charge. With the introduction of the latest 200 watt chargers, you can now get your phone from 0 to 100% in minutes. But does fast charging come at a cost? In this article, we’ll explore the history of phone chargers and whether or not fast charging is actually harmful to your smartphone battery.



In-short :

  • Fast charging technology can quickly charge your smartphone battery without causing significant long-term damage.
  • The charging process needs to be managed correctly and built-in safeguards can protect the battery from overheating or overcharging.
  • Proper care of your phone battery, such as avoiding extreme temperatures and using a high-quality or recommended charger, can help ensure that your battery lasts as long as possible.


Most smartphones use lithium-ion batteries, which are rechargeable batteries commonly used in portable electronics. These batteries store energy by moving lithium ions from the positive electrode to the negative electrode during charging and back again during discharging.

Fast charging technology can be a convenient way to quickly charge your device, but there have been concerns that it can cause long-term damage to your smartphone battery. However, recent research has shown that fast charging may not necessarily be harmful to your battery, as long as the charging process is managed correctly.

Fast-charging batteries work in two phases. The first phase applies a blast of voltage to the empty or nearly empty battery. This gives you that blazing charge of from 50% to 70% in the first 10, 15 or 30 minutes. During this phase, batteries can absorb a charge quickly without major negative effects on their long-term health.

The second phase is where phone-makers have to slow down and carefully manage the charging speed to avoid damaging the battery. Many fast charging technologies are designed to charge the battery in a specific way that minimizes heat and stress on the battery. Additionally, manufacturers may include built-in safeguards to protect the battery from overheating or overcharging.

Overcharging used to cause anxiety among phone owners. The fear was that keeping a phone constantly plugged in could charge a battery beyond its capacity, making the battery unstable, which could degrade overall battery life or cause the battery to catch fire. However, a battery’s management system is designed to shut off the electrical charge once a battery reaches 100%, before it can overcharge.

So, does fast charging ruin your phone battery or not? While some experts argue that it does indeed damage the battery over time, others suggest that the technology has advanced to the point where it’s no longer a significant concern. Ultimately, the answer may depend on several factors, including the type of phone, the charger used, and how frequently it’s charged. Regardless of the charging method, all batteries will eventually degrade over time. The key is to take proper care of your phone battery, such as avoiding extreme temperatures and not allowing it to completely drain before charging. Additionally, it’s recommended to use a high-quality or recommended charger.

Finald Words

If you’re someone who relies heavily on your phone and needs to charge it quickly, then fast charging may be a necessary convenience. Just make sure to take proper care of your battery and use recommended chargers to ensure that your battery lasts as long as possible.
