Losing track of your keys or bag can send you into a panic mode within seconds. That is exactly why Apple introduced the AirTag, a tracker to help locate your essentials in seconds. Yet, many users find themselves wondering about one key detail: how does the battery work?
Unlike most Apple devices, AirTag don’t require charging at all. However, that doesn’t mean you can ignore it entirely. Let’s explore how long the AirTag battery life is, and a better alternative.

Why AirTag’s “No Charging” Design Is a Double-Edged Sword
Although not needing to charge an AirTag sounds like a great idea, it’s not always perfect. Since you will have to deal with a CR2032 replacement later, let’s look at both sides before you think it’s completely hassle-free:

1. The Hidden Cost of Battery Replacements
While AirTag don’t need charging, their CR2032 coin batteries won’t last forever. On average, AirTag battery life is about one year with normal use. A new one usually costs around $2 individually. It’s easy to replace, but the added costs end up surprising many.
2. When AirTag Fails: Real-Life Tracking Gaps
Losing a signal from your AirTag during a critical moment can make a situation worse. Since it can’t plug into a power bank, you’re stuck if the battery dies. It is not the only issue, as a few real-world problems you should know include:
● Battery dies faster in extreme heat or cold, which affects the AirTag’s internal chemical reactions.
● Reset becomes necessary once the battery runs out, delaying your ability to locate lost items.
● Some people misuse AirTag to secretly track others, raising serious concerns.
Find My Wallets vs AirTag: Which Tracking Solution Wins for Your Essentials?
AirTag work well, but they’re not the only smart trackers out there. Many Find My integrated accessories, like ESR’s Geo Wallet, offer different features. The following is a comparison of what each option brings to the table to help you decide:

1. Say Goodbye to Batteries: How Integrated Trackers Work
Unlike AirTag, some trackers don’t need battery changes at all to offer much more comfort. As a magnetic wallet with built-in tracking works differently, let’s look at what makes them stand out below:
1. Interchangeability
AirTag must fit into something like a wallet card slot. On the other hand, magnetic wallets with built-in trackers combine, cutting device clutter by 25% and keeping your carry slimmer without extra add-ons.
2. Ecosystem Dependence
Both use Apple’s Find My Network, but AirTag relies on iPhones with UWB for exact tracking. Integrated wallets just need Bluetooth, making them more flexible with older iOS devices or limited-range needs.
3. Scenario Replacement
Everyday items (wallets/cards): Integrated wallets win with their slim designs and no added bulk. Occasional-use items (keys/luggage): An AirTag with a holder is cheaper and works well for infrequent tracking.
Conclusion
Neither solution fully replaces the other. Integrated wallets are ideal for daily carry items, but 79% do consider wallet thickness as a major annoyance. On the other hand, AirTag works best for less-used things, where tracking cost and size matter less.

Pro Tips: Extend Your Tracker’s Lifespan
Many people wonder, “How long does an AirTag battery last?” So, how can you make it last even longer?
Keeping your tracker in top shape takes more than just regular use. Simple habits, like charging with a
