For daily charging of the Bose QuietComfort 35 QC35/QC35 II headphones, charge them whenever needed. It’s not necessary to fully charge them; maintaining a charge level between 20% and 80% is best for extending lithium battery life and is the golden rule of maintenance.
1. As recommended by Bose, you can use the included USB cable to connect to a computer or a standard 5V⎓1A charger for daily charging.
Unnecessary: Do not intentionally drain the Bose QuietComfort 35 QC35/QC35 II headphones battery to 0% every time before charging. Over-discharging is the culprit that damages the battery.
Avoid using high-power fast charging adapters (such as mobile phone fast charging adapters) to avoid damaging the battery.
2. Long-term storage: Store the Bose QuietComfort 35 QC35/QC35 II headphones battery at approximately 40%-50% charge, away from high temperatures. Charge the headphones every 1-2 months to prevent the Bose QuietComfort 35 QC35/QC35 II headphones from running out of power and dying.
Store the headphones in a cool, dry environment.
Never store the headphones with the battery completely depleted for an extended period, as this can easily lead to Bose QuietComfort 35 QC35/QC35 II headphones battery failure.
3. Avoid placing the headphones in high-temperature environments such as inside a car exposed to direct sunlight or near a heater, as this will accelerate battery aging in the Bose QuietComfort 35 QC35/QC35 II headphones.
Regarding overnight charging: Charge with confidence! Bose explicitly states that the QC35’s lithium battery has a robust protection mechanism and automatically stops charging once fully charged, so “charging overnight” is generally safe.
Although there is overcharge protection, from a maintenance perspective, developing the habit of “charging only when needed, stopping when the Bose QuietComfort 35 QC35/QC35 II headphone battery is fully charged” is still recommended.
4. Turn off the headphones when not in use to keep them cool. Develop a good habit: Always turn off the headphone power switch when not in use to avoid unnecessary battery drain.
If you experience headphone lag or connection issues, try resetting them; this can resolve many minor problems.
Avoid using the headphones in extremely cold environments below -10°C or extremely hot environments above 40°C, as this can temporarily or even permanently affect the Bose QuietComfort 35 QC35/QC35 II headphones battery performance of the Bose QuietComfort 35 QC35/QC35 II headphones.
Do not allow liquids to enter the earphones, and do not use any solvents or sprays for cleaning. Simply wipe with a soft cloth.
5. In summary, lithium-ion batteries have a limited lifespan, but developing good daily habits, such as charging whenever needed, avoiding over-discharging and overheating, and turning off the headphones when not in use, can effectively extend the battery life of your Bose QuietComfort 35 QC35/QC35 II earphones.
