If you’re an AirPods user, this scenario probably looks all too familiar: one bud is almost dead while the other is sitting pretty at 100%. Meanwhile, your charging case is halfway full and you’re left scratching your head, wondering what went wrong. Sound familiar? You’re not alone.
This bizarre but common battery imbalance is more than just a tech glitch—it actually tells a story about how people use their earbuds. And the explanation? Simple: most users only wear one earbud at a time.
Let’s dig into why this happens, what it means for your battery health, and why AirPods users around the world totally get this struggle.
The One-Ear Habit—More Common Than You Think

Whether you’re multitasking, working remotely, biking through the city, or just trying to hear your surroundings, using only one earbud has become second nature to many. Usually, it’s the right bud that gets favored. Why? It’s the default mic for most AirPods, and people tend to be right-handed.
The result? Your right AirPod stays in use longer, while the left gets a break in the case—or vice versa if you’re a leftie or just rebellious by nature.
Why This Usage Drains One Bud Faster
Think of it like driving a car with only one tire on pavement and the other on a pillow. The one on the road is doing all the work—it’s picking up your voice, playing your music, handling noise cancelation (if you’re using Pro models), and dealing with Bluetooth connectivity. That takes juice. A lot of it.
Meanwhile, the unused earbud is either chilling in the case or quietly sleeping in your ear. No energy burned, no battery drained.
So when you check your battery status and see something like Right: 100%, Left: 11%, don’t panic. It’s not broken. It’s just been pulling solo duty.
You’re Missing Out on Stereo Sound (Yes, Really)
Here’s something most people don’t think about: when you use only one earbud, you’re losing half of the sound experience.

Stereo audio is designed to deliver two distinct audio channels—one for each ear. This gives you depth, direction, and the kind of immersive sound that makes your music or podcast feel alive. Ever hear footsteps creeping up in a movie or a harmony swirl across your head in a song? That’s stereo magic.
When you’re using just one earbud, everything collapses into mono. You still hear the content, but you lose the dimension.
It’s like listening to a symphony through a straw.
There’s a Time and Place for One-Ear Listening
Still, there are good reasons to use only one AirPod:
- Safety: Jogging or cycling? Keeping one ear open can save your life.
- Awareness: Need to hear coworkers, announcements, or kids around you? One earbud lets you stay plugged in and alert.
- Battery-saving: Rotating between left and right can stretch usage time without needing to charge the case constantly.
- Calls: For voice calls, stereo is irrelevant—you just need a mic and speaker.
In short, one earbud use isn’t wrong. It’s practical. But it does have trade-offs.
Tips to Keep Your Battery Balanced

If you’re tired of lopsided battery levels or worry it’s hurting your AirPods, here’s what you can do:
- Switch ears regularly – Don’t let just one side do all the heavy lifting. Rotate every call or every few hours.
- Use both earbuds for media – When possible, enjoy your favorite tracks or movies the way they were meant to be heard.
- Check microphone settings – You can set your mic to automatically switch between left and right, or assign one permanently.
- Keep both charged – Don’t forget that using one doesn’t mean the other’s always ready. Make sure you rotate charging.
- Restart the pairing – Sometimes, bugs can mess with battery readouts. A quick unpair and repair can recalibrate them.
That Charging Case Mystery
And let’s not forget the charging case. Ever notice how it’s never at 100% when you expect it to be?
Here’s the thing—your AirPods case charges your buds every time you put them back in. If you’re popping one in and out all day, the case is working overtime for that one earbud, slowly draining itself even if you think it’s not doing anything.

So while your case says 65% and one AirPod is dead, the math actually adds up. Just… not the way you expected.
Conclusion: AirPod Users Get It
Owning AirPods comes with a set of invisible rules and quirks that only fellow users really understand. Lopsided battery levels? Totally normal. Audio that sounds flat when you’re using one bud? Welcome to mono mode. Case at 65% with one bud at 11%? That’s just life.
So next time someone asks why your left AirPod is dead again, you’ve got the perfect answer: “Because I only wear one—and that one works overtime.”
Now go charge your case. You’ve got more half-battery struggles ahead.
