Nothing ruins a commute like earbuds dying halfway through your playlist. You're on the bus, twenty minutes from your stop, and the left bud gives up first. Then the right one follows. Silence — except the traffic. I hear this complaint more than any other. And honestly? Most of the time it's not a faulty battery. It's habits. 1. Stop charging to 100% every single night Lithium batteries age fastest when they sit at full charge. If your case lives on the charger all night, every night, you're quietly shortening its life. Unplug around 80–90% when you can. I know — nobody does this. But it matters more than any setting tweak. 2. Turn the volume down a notch This is the big one. Listening at 60–70% instead of max volume can add a genuinely noticeable chunk of playtime. Your ears will thank you too. Try it for a week and see. 3. Switch off noise cancellation when you don't need it ANC is brilliant on a noisy bus. In a quiet room? It's just burning power for nothing. Most apps let you toggle it in two taps. Make it a habit. 4. Use one bud for calls Phone calls drain batteries fast. Use mono mode — one bud in, the other resting in the case and charging. You effectively double your talk time, and nobody on the call notices the difference. 5. Keep the case closed An open case keeps the buds awake and connected, sipping power. Closed case, buds asleep. Simple. This alone fixes the "they were full last night" mystery for a lot of people. 6. Clean the charging contacts Pocket lint and dust break the connection between bud and case. The buds sit there all night "charging" without actually charging. A dry cotton bud once a week. That's it. 7. Update the firmware Boring advice, I know. But manufacturers do quietly fix battery-drain bugs in updates. If your companion app shows an update pending, don't ignore it for three months. One Bangladesh-specific note With load-shedding, charge the case while the power is on — a half-charged case beats a dead one during a two-hour outage. And avoid leaving it plugged into a cheap multiplug during voltage swings; a decent charger is worth it. If I had to pick just two habits: watch the volume, and close the case. Those two alone will change how often you reach for the charger.
