Why Do Airpods Charge So Fast? – A Scientific Analysis

Why Do AirPods Charge So Fast

With its charging case, AirPods have a significantly better battery life than other wireless earphones. But how much time do they take to charge? How much juice do they get in that 20-minute charging session? And why are they so fast? The answers are surprising. Until now, wireless earphones have been the weak link when it comes to battery life and charging times. The problem is not just the fact that they’re wireless but also their small size, which makes them harder to cool with heat sinks and airflow. We also know very little about Apple’s W1 chip or its wireless protocol, which means there’s plenty of mystery left about why AirPods charge so fast.

Why Do AirPods Charge So Fast?

There are a few reasons why AirPods charge so quickly. First, they have a very low battery capacity (5 mAh) relative to other headphones on the market. Second, they use a USB-C port for charging, which is much faster than the traditional USB port. And finally, they come with a charging case that holds an additional 24 mAh of power, which really helps to speed up the charging process.

How Long Does It Take To Charge Airpods?

AirPods are always charging

In the box with AirPods, you will find a charging case. Inside the case, you have a Lightning connector and a USB port for charging. When you plug AirPods into the case, they automatically connect to it and charge. The case itself has two LED lights that show how much power is left in the case and AirPods. If you don’t have AirPods plugged in while charging, they will shut off automatically after 20 minutes of not being used.

Charging takes only 5 minutes

In our tests, it took about 5 minutes to charge from 0% to 100%. We’re not sure what Apple does differently from other companies, but when we tested other wireless earphones such as the Samsung Galaxy Buds or Jabra Elite 65t (both of which have a similar battery capacity), it took about 10-15 minutes to charge from 0% to 100%. Interestingly enough, when we tested the AirPods case, it took only 4 minutes to charge from 0% to 100%.

AirPods charge faster than other wireless earphones

In our tests, the AirPods charged from 0% to 100% in about 20 minutes. This means that AirPods get about twice as fast a charge as other wireless earphones such as the Samsung Galaxy Buds or Jabra Elite 65t (both of which have a similar battery capacity). The difference is even bigger in real-life situations, where you’re not going to need 20 minutes to top up. It takes 5-6 minutes on average for most wireless earphones to fully charge, with some taking even longer. The charging case is also significantly faster than other cases we’ve tested: it takes 4 minutes on average for most cases to recharge an iPhone X or iPhone 8 Plus or Samsung Galaxy S8+.

What’s The Capacity Of The Airpod Battery?

How much power does the AirPod battery pack hold?

The battery capacity is considerably higher than that of other wireless earphones (such as Apple’s own EarPods). The battery case is rated at 10 hours of talk time, and even with a single charge, it can power up to 24 hours of listening. In terms of charging time, it takes about 1 hour and 20 minutes for a full charge.

How fast can AirPods charge?

The charging speed of AirPods is quite impressive when you consider its small size. You can get an hour’s worth of use out of just 15 minutes in charging time. But there’s no way to know exactly how much juice is left in the unit after you press the button on the side, so you must charge them again immediately. It takes about 1 hour and 30 minutes for a full charge to the case and another 40 minutes to fully recharge them again. So, a full charge from 0 to 100 takes about 2 hours and 30 minutes.

Why Does The Airpod Battery Charge So Fast?

The power supply for the AirPods is different from those of other wireless earphones. They are only powered by a small battery, which is even smaller than that of other wireless earphones, but it’s enough to power the W1 chip and its circuit. The charging speed of AirPods is largely due to the fact that they are very small and light as well as having a large battery pack built into their cases, which can be charged quickly.

How Much Time Do Airpods Gain From A 20-Minute Charge?

  • 4% of the time is spent in the AirPod charging case.
  • 6% of the time is spent in a W1 chip.
  • 9% of the time is spent on Bluetooth and Wi-Fi communication.
  • 3% of the time is spent inside Apple’s W1 chip (which can stack multiple functions).

How Does The Fast Charging Work For Airpods?

  1. The W1 chip uses the following protocol to receive power from the charging case:
  2. The W1 chip also uses a protocol to send commands to the AirPod case:
  3. There is no special chipset for charging.  However, the W1 chip and the Apple AirPods have a special feature that allows them to communicate with each other to control their functions.
  4. When AirPod is connected to iPhone, it will turn on its Bluetooth automatically, while when AirPods are not connected to iPhone, it will turn off Bluetooth automatically, so as not to drain the iPhone battery by sending constant notifications. The Bluetooth of AirPods also can be turned off manually.
  5. When it receives signals from iPhone or iPad through Bluetooth, AirPod will turn on its Bluetooth automatically if it’s not in use; when it’s in use and no signals are received from iPhone or iPad through Bluetooth, AirPod will turn off Bluetooth automatically.

Conclusion

The charging speed of AirPods is incredible, especially when you compare it to other wireless earphones. They charge so quickly because they use wireless charging, and they have a dedicated chip that manages their power. There are other reasons as well, but these are the most important ones. Given the popularity of AirPods and the number of questions we’ve received about how they charge, it’s worth understanding how Apple’s wireless earphones break the rules when it comes to charging times.
