  • Next week is my last week working at Bose, funny to read this. Also, I’m one of the few remaining battery guys. Ear bud battery degradation can happen from charge cycles or time spent at full SoC. For cycles, theyre designed to easily handle hundreds of charge cycles before their capacity degrades below 80% which is the industry standard for ‘end of life’. But 80% is hardly end of life. Lithium cells don’t like being left at 100% SoC, the high voltage stress damages the chemistry. All that being said, after years of power use you can easily expect at least 80% playtime you had on day one.
