Do AirTags Need to Be Charged?



Are you intrigued by Apple’s latest innovation, the AirTag? These compact tracking devices have taken the market by storm, offering a simple solution for keeping tabs on your valuable possessions. If you’re considering getting an AirTag or have one already, you might be wondering: Do AirTags need to be charged?

In this article, we’ll delve into the details to answer this question and provide you with a comprehensive understanding of how AirTags work, their battery life, and other essential information. So, let’s dive in!

Understanding AirTags

To truly grasp whether AirTags require charging, we must first understand what AirTags are and how they function.

What Are AirTags?

AirTags are small, coin-shaped tracking devices developed by Apple. They are designed to help you locate and keep track of your belongings, such as keys, wallets, backpacks, or even your pet.

How Do AirTags Work?

AirTags utilize a combination of Bluetooth technology and the vast network of Apple devices to pinpoint their location. Here’s a brief overview of how they work:

  • Bluetooth Connectivity: AirTags use Bluetooth to connect to nearby Apple devices, such as iPhones, iPads, and Macs.
  • Ultra-Wideband (UWB) Technology: AirTags incorporate UWB technology for precise location tracking within a short range.
  • Apple’s Find My Network: When an AirTag is out of your Bluetooth range, it can leverage Apple’s Find My network, a vast community of Apple devices, to anonymously and securely update its location.

Now that we have a basic understanding of AirTags, let’s move on to the crucial question of their battery life.

Battery Life of AirTags

AirTag users are often concerned about battery life, and rightfully so. Let’s explore this aspect in more detail.

Battery Type

AirTags are powered by a standard CR2032 coin cell battery, which is widely available and easily replaceable.

Battery Life Expectancy

The good news is that AirTags comes with an impressive battery life. On average, a single CR2032 battery can power an AirTag for about one year. However, the actual battery life may vary depending on usage patterns.

Low Battery Notifications

AirTags are smart devices that will notify you when the battery is running low. You’ll receive a notification on your connected Apple device when it’s time to replace the battery.

Do AirTags Need to Be Charged?

The straightforward answer is no. AirTags do not need to be charged. Instead, they rely on replaceable coin cell batteries. This design choice by Apple offers several advantages:


AirTags are incredibly convenient since you don’t need to worry about recharging them regularly. Replace the battery when it’s depleted, and your AirTag is good to go for another year.

No Downtime

Charging your tracking device can be frustrating, especially if you’re in a hurry to find your lost item. With AirTags, you can swap out the battery in a matter of seconds, ensuring that your tracking device is operational at all times.

Maximizing AirTag Battery Life

While AirTags doesn’t require charging, there are some tips and tricks to maximize their battery life for an extended period of use.

Optimize Settings

  • Precision Finding: Only enable Precision Finding when you need it, as it consumes more battery power.
  • Sound Alerts: Adjust the frequency of sound alerts to strike a balance between battery life and convenience.

Update Software

Regularly update your AirTag’s firmware and ensure that your connected Apple device is running the latest software. These updates often include improvements in battery optimization.

Use Accessories Wisely

If you decide to attach an AirTag to an item that frequently moves (like a pet collar), make sure the attachment is secure. Excessive movement can trigger unnecessary Bluetooth connections, draining the battery faster.

Replace the Battery Promptly

When you receive a low battery notification, replace the CR2032 battery promptly to prevent any downtime in tracking your belongings.


In conclusion, AirTags is a remarkable solution for tracking and locating your valuables without the need for regular charging. Their efficient use of standard CR2032 coin cell batteries ensures that you can enjoy hassle-free tracking for up to a year before needing to replace the battery.

Apple’s seamless integration of Bluetooth and UWB technology, along with the Find My network, ensures precise location tracking without compromising on battery life. So, if you’re looking for a reliable tracking solution, AirTags are a fantastic choice!
