Sony WH-1000XM3 battery aging: What you really need to be wary of is "low battery jumping off a cliff"
TheSony WH-1000XM3 Headphones Batteryof Sony WH-1000XM3 is declining. The most alarming thing is not that the battery life is slowly shortening, but that the low battery is "jumping off a cliff": the battery shows that there is still 30%-40%, but it may quickly drop to shutdown. This is a typical sign of XM3 battery aging, and it affects the experience more than simply using it for a few hours less.
Normal aging is usually gradual. Some users have used it for more than two years, and the battery life is still close to its original state; others have significantly reduced battery life after a year and a half. Individual differences vary greatly. However, once "the Sony WH-1000XM3 Headphones Battery seems normal in the middle and suddenly collapses at low battery", it often means that the internal resistance of the battery has increased significantly and the output cannot be stable. A clearer warning is: when the battery power is lower than 40%, the noise reduction will fail first, and the noise reduction will suddenly turn off, causing intermittent noise or the noise floor will increase. This is because the noise reduction chip requires stable power supply, and the aging battery cannot sustain peak power consumption when the battery is low.
In addition, even if the library machine has been idle for a long time, even if it looks brand new, it may experience a power drop and abnormal noise reduction due to battery passivation. When purchasing second-hand products, don’t just look at “can still be turned on” and listen for a short period of time. You should actually measure the full Sony WH-1000XM3 Headphones Batterylife at medium volume and turn on noise reduction, and focus on observing the performance after the battery power drops below 40%: whether it loses power quickly, whether the noise reduction fails, and whether it shuts down suddenly.
Generally speaking, the durability of XM3 batteries is polarized: a properly maintained machine can still play for many years; but if it jumps off a cliff with low battery or the noise reduction fails with the battery, it means that the aging is quite serious, and you should consider replacing the Sony WH-1000XM3 Headphones Battery or purchase with caution.
