Music for days, or a quick phone top-off.

Posts Since Apple removed the headphone jack and introduced AirPods in 2016, wireless earbuds have become a staple accessory. Their compact and lightweight design makes them incredibly versatile, suitable for both indoor and outdoor activities, as well as work and leisure. However, this convenience comes with a downside: their surprisingly short lifespan.

Design Constraints Limit Battery Size

The simplest way to enhance the longevity of any device is to include a larger battery. A higher initial capacity delays the onset of battery degradation issues. Unfortunately, wireless earbuds face significant limitations due to their extremely small size and ergonomic requirements.

Comfort is paramount when it comes to wearable technology. Nobody wants earbuds that feel uncomfortable, fall out during exercise, or cause fatigue during prolonged calls or music sessions. As a result, manufacturers prioritize reducing size and weight to meet these ergonomic demands.

Bigger batteries could provide extended usage times and improve longevity. Some earbuds, like the HMD Amped Buds, claim multiple days of battery life, but their cases are bulkier and can feel more cumbersome in your pocket.

Lithium-ion batteries degrade fastest when left empty or fully charged for extended periods. They are best preserved when kept around 50% charge. This applies equally to wireless earbuds and smartphones.

The challenge is that while you can manually disconnect your phone when it reaches 50%, earbuds stored in their case are perpetually either charging or fully charged—both conditions accelerate degradation. Regardless of your intentions, the case will continue to supply power to the earbuds until they are fully charged or the case is depleted.

In essence, if you're mindful of maintaining your phone's battery health, you can be deliberate about it. With earbuds, however, this isn't an option. While the case ensures the earbuds are always accessible, it inadvertently creates ideal conditions for battery deterioration.

Users Prefer Keeping Earbuds Fully Charged

When your phone's battery is low, you can activate power-saving mode to drastically reduce consumption, allowing you to use it even when it's only half full. Wireless earbuds lack such a feature. The best you can do is disable active noise cancellation or transparency mode, which offers some battery savings but not enough to justify skipping regular charging.

People prefer keeping their earbuds fully charged for convenience, and manufacturers cater to this preference. Reverse wireless charging allows you to top up your earbuds using your phone, though this generates excess heat, further damaging the battery.

The future isn't (fully) wireless.

Modern smartphones let you stop charging at 80% to extend battery life. On Samsung phones, you can disable fast charging to minimize heat. On iPhones, you can monitor battery health through a dedicated menu.

Wireless earbuds lack such features because users prefer keeping them fully charged. Consequently, there's no way to extend their lifespan even if desired.

Battery Replacement for Wireless Earbuds Is Rare

Smartphone battery replacements are common, and on iPhones or Samsung devices, you can easily visit an authorized repair shop for a quick swap. If all other components are functional, replacing the battery is the simplest way to extend a phone's life.

While battery replacement exists for wireless earbuds, it's uncommon. Replacing a smartphone battery is straightforward, but earbuds come in various designs, complicating repairs. Additionally, earbuds are relatively inexpensive and viewed as disposable compared to phones, which are long-term investments.

Battery degradation isn't the only factor contributing to earbud wear. How and where we use them also plays a role. Over-ear headphones are typically used indoors due to their size and focus on immersive sound. Wireless earbuds, being smaller and more versatile, accompany us everywhere and handle various audio tasks.

Transparency mode encourages users to keep them on constantly, removing them only for recharging. Over time, outdoor use can lead to dust and debris clogging the speaker grills. Drops on sidewalks from improper seals can damage the casing. Sunlight exposure can discolor the plastic housing. Lint and microplastics from pockets or bags can block the USB-C port. During workouts, sweat can seep into internal components, speeding up corrosion.

Wireless earbuds are too versatile for their own good. Everything we enjoy about them also leads to faster degradation. From constant charging cycles to the absence of battery health features and the physical stress of daily use, these devices aren't built to endure. Manufacturers aren't intentionally designing them to fail quickly; it's inherent to their form.

To extend their lifespan, you can minimize charge cycles by limiting power-intensive features like ANC. Foam eartips can provide a tighter seal for better passive noise isolation, reducing battery drain and slowing degradation. Still, this won't match ANC's effectiveness, but it helps. The less the battery depletes, the fewer times it needs recharging, delaying degradation.
