You charge your earbuds case to 100% before bed. You wake up, haven’t touched it, and it’s sitting at 70%. Or worse, you go a few days without using your earbuds at all and come back to find the case completely dead. If this sounds familiar and you’ve already searched around only to find articles written specifically for AirPods that don’t quite apply to your Galaxy Buds or budget earbuds, this guide is for you.
The good news is that this happens for a small, predictable set of reasons across pretty much every brand of true wireless earbuds, not just Apple’s. Once you know what’s actually going on, most cases are fixable in a few minutes.
Why Earbuds Cases Lose Charge Even When You’re Not Using Them
The core thing to understand is that your earbuds case isn’t just a dumb plastic box holding a battery. It’s a small charging hub with its own internal circuitry, and depending on the model, it’s also doing several things in the background that quietly consume power even while it’s sitting closed on your desk.
The case is actively topping up the earbuds inside it. This is the single most common and completely normal reason a case loses charge over time. If your earbuds weren’t at 100% when you put them in the case, the case battery is being used to bring them up to full, and that process continues to draw a small amount of power even after they reach 100%, since lithium-ion batteries lose a tiny amount of charge naturally and the case periodically tops them back up to keep them ready. This is by design, not a fault.
Bluetooth radios inside the case stay semi-active. Most modern earbuds cases have a small Bluetooth chip that periodically checks in with your phone, even with the lid closed, so the earbuds can reconnect instantly the moment you take them out. On some models, simply opening and closing the lid repeatedly, even just to check the battery level, wakes this radio up each time and adds up over a day of casual lid-flipping.
Location-tracking features draw power continuously. If your earbuds or case support a “find my device” style feature, similar to Apple’s Find My network, this requires the case to periodically broadcast its location in the background. This is genuinely one of the biggest hidden drains reported across both Apple and Android ecosystems, and it’s also one of the easiest to fix since it’s usually a single toggle.
One earbud isn’t seated properly, so the case keeps trying. This is an extremely common and specific cause, especially with case designs that use small magnetic charging pins rather than a snug physical fit. If one earbud isn’t making full contact with the charging pins, even by a fraction of a millimeter, the case can repeatedly attempt to charge it, draw power doing so, and still fail to actually top it up, which drains the case noticeably faster than normal without ever fully charging that earbud.
Firmware issues can keep the case in a high-power state. Less common, but real. A buggy firmware version on the case itself can occasionally cause it to skip entering its proper low-power sleep state, leaving background processes running continuously instead of idling down.
How to Actually Fix It, Step by Step
Work through these in order. Most people find their answer in the first three steps.
Step 1: Check that both earbuds are seated correctly and the contacts are clean. Remove both earbuds from the case completely. Look closely at the charging pins, both on the earbuds themselves and inside the case, for any visible dust, lint, or earwax buildup. Wipe both sets of contacts gently with a dry, soft cloth or a cotton swab. Place the earbuds back in firmly until you feel or hear them click or seat properly, and confirm the charging indicator light responds. A surprising number of “the case is draining” complaints turn out to be “one earbud was never actually charging in the first place,” which means the case has been fighting a losing battle this whole time.
Step 2: Turn off any location-tracking or “find my” features if you don’t rely on them. Open your earbuds’ companion app, whether that’s Galaxy Wearable for Samsung Buds, a generic manufacturer app for budget earbuds, or your phone’s Bluetooth accessory settings. Look for a setting along the lines of Find My Buds, Find My Device support, or similar. If you don’t frequently misplace your case, turning this off removes one of the most consistently reported drains across brands.
Step 3: Disable Ear Detection if your earbuds have it and you don’t need it. Many modern earbuds use a small sensor to detect when they’re actually in your ear, which lets them pause audio automatically when you take one out. This is convenient, but the constant sensor activity does cost some battery, both in the earbuds and indirectly through more frequent communication with the case. If you don’t rely on this feature, your companion app almost always has a toggle to turn it off.
Step 4: Stop habitually opening and closing the case when you’re not actually using the earbuds. It’s a small habit, checking the battery level by popping the lid open throughout the day, but each open-close cycle wakes up the Bluetooth radio and re-triggers a connection attempt with your phone. If you’re just checking battery percentage, most companion apps let you check this from your phone’s notification panel or widget instead, without touching the physical case at all.
Step 5: Update the firmware through your companion app. This applies whether you’re on Samsung, a generic Android-paired model, or anything in between. Firmware updates for both the earbuds and the case itself are pushed through the manufacturer’s app, and they regularly include fixes specifically targeting power management bugs. Check for a pending update before assuming anything is hardware-broken.
Step 6: Try a full reset if the above doesn’t resolve it. Every brand’s reset process differs slightly, but it generally involves holding a button on the case (sometimes with the lid open, sometimes closed, check your specific model) for around 10 to 15 seconds until the indicator light changes pattern, confirming a reset. This clears out any corrupted internal state that might be keeping the case from entering proper low-power standby. Forget the device from your phone’s Bluetooth settings afterward and re-pair from scratch.
When the Drain Is Actually Normal and Not a Problem
It’s worth setting realistic expectations here, since not every bit of battery drop is actually a malfunction. A charging case maintaining a near-full charge on the earbuds inside it will always lose some battery over time, that’s simply what it’s built to do. The real question isn’t whether the case loses any charge at all when sitting unused, it’s how much and how fast.
As a rough benchmark, a healthy case storing fully charged earbuds should comfortably hold its charge for several days to a week or more of light, idle storage without dropping dramatically. If your case is going from full to completely dead overnight with the earbuds already fully charged and untouched, or it can’t get through more than a day or two of normal use between charges despite modest daily listening time, that points to one of the fixable causes above rather than expected behavior.
When It’s a Hardware Problem, Not a Settings Problem
If you’ve worked through every step above, including a full reset and firmware update, and the case is still draining dramatically faster than it used to, especially if this started suddenly after the case previously worked fine, you’re likely looking at a genuine hardware issue rather than something fixable through settings.
The most common culprit at this point is a single earbud with a degrading internal battery that’s drawing excessive power trying to maintain its charge level, even while appearing to charge normally. You can sometimes confirm this by checking each earbud’s individual battery percentage in your companion app rather than just the combined case reading, since a steep difference between the left and right earbud’s battery health is a strong signal pointing to one specific faulty unit rather than the case itself.
Most manufacturers, including Samsung, cover battery-related defects under warranty within the first year, so it’s worth checking your specific brand’s support page and warranty terms before assuming you need to replace the entire set.

Quick Reference Checklist
If you just want the short version to work through right now: clean both sets of charging contacts and confirm both earbuds seat properly, turn off Find My or location tracking if you don’t need it, turn off Ear Detection if you don’t rely on it, stop repeatedly opening the case just to check battery level, update firmware through the companion app, and if none of that helps, do a full factory reset before assuming it’s a hardware fault.
Walking through these in order takes about ten minutes and resolves the overwhelming majority of cases, regardless of which brand of earbuds you’re actually using.
FAQ — Earbuds Case Battery Draining Fast
Why does my earbuds case lose battery even when I’m not using it?
The case is usually still topping up the earbuds inside it to keep them at full charge, and on many models the Bluetooth radio stays semi-active so the earbuds can reconnect instantly when you take them out. Both of these are normal background processes, not a fault.
Is it normal for an earbuds case to drain overnight?
A small drop is normal if the earbuds weren’t fully charged when you closed the case. Going from full to completely dead overnight with the earbuds already at 100% and untouched is not normal and points to one of the fixable causes like a poorly seated earbud or a stuck location-tracking feature.
Does turning off Find My Buds or Find My Device actually help?
Yes. Location-tracking features require the case to periodically broadcast its position in the background, and this is one of the most consistently reported sources of unexpected battery drain across both Samsung and generic Android-paired earbuds.
Why does only one earbud lose charge while the other stays full?
This is almost always a seating problem. If one earbud isn’t making full contact with the charging pins, even slightly, the case will repeatedly try and fail to charge it, which drains the case faster while that earbud never actually reaches full charge.
When should I stop troubleshooting and assume it’s a hardware problem?
If you’ve cleaned the contacts, disabled Find My and Ear Detection, updated the firmware, and done a full factory reset, and the case is still draining dramatically faster than it used to, especially if this started suddenly, that points to a genuine hardware issue, most often a single degrading earbud, rather than something fixable through settings.
