Apple AirTags have quickly become one of the most popular tracking accessories on the market, and it’s easy to see why. Since launching, they’ve been used to keep tabs on everything from keys and wallets to work passes, TV remotes and even vehicles. Slip one into a bag or attach it to something valuable, and you have near-instant peace of mind if it ever goes missing.
At the heart of AirTag’s appeal is Apple’s Find My network, a vast, crowdsourced system made up of hundreds of millions of Apple devices worldwide. When an AirTag is out of Bluetooth range of its owner, nearby iPhones, iPads or Macs can anonymously detect its signal and relay its location back to the owner. All of this happens securely and in the background, without other users knowing they’re part of the process.
How the Find My Network Works
The Find My network is what makes AirTags so powerful compared to traditional Bluetooth trackers. Instead of relying solely on your own phone, AirTags effectively “borrow” connectivity from Apple devices around them. This turns cities, towns and even remote areas into a giant passive tracking mesh.
When combined with Precision Finding on supported iPhones, AirTags can guide users directly to a lost item using on-screen directions, sound cues and haptic feedback. This system has become even more capable with newer AirTag hardware.
What’s New With the Latest AirTag Model
In January 2026, Apple released an updated AirTag featuring the U2 chip, upgraded Bluetooth and a louder built-in speaker. The new model offers significantly enhanced range for precision tracking when paired with iPhones that also feature the U2 chip, such as the iPhone 15 Pro and later models, excluding the iPhone 16e.
Apple Watch support has also improved. Owners of Apple Watch Series 9, Apple Watch Ultra 2 and later models can now precisely locate items directly from their wrist, provided the watch includes the U2 chip. This makes AirTags more versatile than ever, particularly for users who rely heavily on wearables.
The Battery Life Problem Many Users Experience
Despite all the improvements, one long-standing issue continues to frustrate many AirTag owners: battery life. Apple officially claims up to one year of use from a standard CR2032 coin cell battery, but real-world usage often tells a different story.
Many users report needing to replace the battery after just four to six months. Some even claim replacements are required every one to two months, particularly for AirTags attached to frequently moved items like vehicles or backpacks. Cold temperatures, heavy use of Precision Finding and low-quality coin cells can all contribute to this reduced lifespan.
A dead AirTag battery doesn’t just mean inconvenience. It can mean the difference between recovering a stolen item and losing it for good.
ElevationLab TimeCapsule Enters the Picture
To address this issue, ElevationLab has launched a product designed to dramatically extend AirTag battery life. Called TimeCapsule, it’s an AirTag enclosure that replaces the coin cell battery with two standard AA batteries.
TimeCapsule comes in two versions, promising battery life of up to five years or even ten years, depending on the batteries used and tracking conditions. That’s a massive leap over Apple’s quoted one-year figure.

Key Features of the TimeCapsule
ElevationLab has designed TimeCapsule with durability and long-term reliability in mind. Its main features include:
- Works with both first and second generation AirTags
- Over 14 times more battery capacity than a CR2032 coin cell
- Uses two AA batteries, with lithium batteries recommended for maximum lifespan
- Easy assembly process with no modification to the AirTag itself
- IP69 waterproof rating for extreme outdoor use
- Premium fibre-reinforced composite construction with CNC machined screws
The product was inspired by a real-world failure case, after a high-value camera bag was stolen and couldn’t be tracked because the AirTag battery had already died.
Setup and Everyday Use
Installing an AirTag into the TimeCapsule is straightforward. The original battery and back plate are removed, the AirTag is placed onto a custom contact inside the enclosure, and the AA batteries are inserted. Once screwed shut, the unit is sealed and ready to go.
The enclosure is designed to be tucked away inside bags, vehicles or equipment cases. It’s discreet enough that a thief is unlikely to recognise it as a tracking device, which is an important consideration for theft recovery.
With an IP69 waterproof rating, TimeCapsule is suitable for harsh environments. It can handle dust, water exposure and outdoor conditions far better than a bare AirTag ever could.
Size, Weight and Practical Trade-Offs
There is, of course, a trade-off. Using two AA batteries makes TimeCapsule larger and heavier than a standard AirTag. The unit measures 4.45 inches by 1.57 inches and is 0.75 inches thick.
While that makes it unsuitable for keys or wallets, it fits comfortably in backpacks, luggage, camera bags, toolboxes and vehicles. For these use cases, the added size is a small price to pay for multi-year battery life.
Pricing and Value Proposition
TimeCapsule is priced at $20, making it surprisingly affordable considering what it offers. When compared to traditional asset trackers, the value becomes even clearer.
Many standalone GPS trackers cost £40 to £50 upfront and require a monthly data subscription that can easily reach £20 per month. They often rely on dated web interfaces and still only deliver battery life measured in weeks or months.
By contrast, TimeCapsule leverages Apple’s Find My network, has no subscription fees, and offers battery life measured in years rather than weeks.
A Potential Disruptor in Asset Tracking
TimeCapsule highlights just how powerful Apple’s tracking ecosystem has become. With the right hardware support, AirTags can rival or even outperform dedicated asset trackers, without ongoing costs or complex setup.
For anyone tracking high-value items over long periods, especially vehicles, equipment or luggage, extending AirTag battery life removes one of the biggest remaining weaknesses in Apple’s system.
While it won’t replace compact AirTags for everyday carry, products like TimeCapsule could quietly disrupt the wider asset tracking market by offering a simpler, cheaper and more reliable alternative built on top of Apple’s existing infrastructure.
