真無線藍牙耳(er)機本來就單(dan)個耳(er)機電(dian)(dian)池(chi)(chi)容(rong)量小，充(chong)電(dian)(dian)倉電(dian)(dian)池(chi)(chi)容(rong)量也不大，放(fang)充(chong)電(dian)(dian)倉取出，充(chong)放(fang)電(dian)(dian)數很(hen)頻繁，電(dian)(dian)池(chi)(chi)損耗會不會很(hen)嚴重，進而影(ying)響壽(shou)命(ming)。

無線耳機使用的可充電紐扣電池

藍牙(ya)耳機電(dian)池(chi)的(de)(de)充(chong)電(dian)循環是按照(zhao)SoC周轉算(suan)的(de)(de)，也就是再(zai)滿(man)電(dian)的(de)(de)狀態下，放(fang)完(wan)電(dian)之后再(zai)充(chong)滿(man)電(dian)，這樣才算(suan)一個(ge)完(wan)整的(de)(de)使(shi)(shi)用循環，而我(wo)們平常(chang)使(shi)(shi)用的(de)(de)時候拿(na)出來(lai)使(shi)(shi)用一會(hui)后又再(zai)放(fang)回去，并沒有用多少電(dian)量，這個(ge)不算(suan)一個(ge)循環，而是具體充(chong)了多少電(dian)量，電(dian)量周轉滿(man)一次設計容量，才算(suan)一次充(chong)電(dian)。也就是說正(zheng)常(chang)聽和放(fang)置，問(wen)題不大(da)。

我們假設鋰電池使用800次循環后容量的衰減會掉到原來的80%容量，這時候算壽命終止， 平均一次循環是5小時使用時間。那么就有4000小時使用時間。 平常來說我們正常使用文件的話，TWS耳機電池一天聽4小時算比較多了， 耳孔都(dou)疼。 那(nei)就有1000天，算下來(lai)的大概可以用3年左右。 那(nei)如(ru)果你每天一直用，8小時，也有一年半。 但是按(an)照這個(ge)使(shi)用頻率， 一般1年左右你就會發現丟掉了一個(ge)。

鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)損耗操作主要是(shi)高溫，在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)低時(shi)持續放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)已經(jing)較高的(de)時(shi)候(hou)(hou)繼續充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。一(yi)般的(de)充(chong)滿(man)(man)問題不太(tai)大，因為真的(de)到(dao)滿(man)(man)了(le)會(hui)(hui)自(zi)(zi)動(dong)截止，只有非常長(chang)期滿(man)(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)狀態(tai)，才(cai)會(hui)(hui)對壽(shou)命有顯著影(ying)響。所以現在(zai)(zai)很(hen)多的(de)無線tws耳機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)都設計了(le)智能充(chong)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)保護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路，在(zai)(zai)進行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)時(shi)候(hou)(hou)自(zi)(zi)動(dong)開(kai)啟(qi)保護(hu)(hu)機(ji)制，當耳機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)到(dao)80%的(de)時(shi)候(hou)(hou)會(hui)(hui)自(zi)(zi)動(dong)切換成慢充(chong)功能，直到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)滿(man)(man)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，然后自(zi)(zi)動(dong)停止充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而當你使用的(de)時(shi)候(hou)(hou)，放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)一(yi)般會(hui)(hui)控制在(zai)(zai)剩余5%到(dao)10%的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)（保護(hu)(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)過度(du)的(de)深(shen)度(du)放(fang)(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，導(dao)致損害電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)），不過顯示的(de)話是(shi)使用完電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，也(ye)就是(shi)顯示沒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。在(zai)(zai)正常的(de)使用情況下(xia)，有溫度(du)超限、巨大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)情況下(xia)，對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)損耗很(hen)小，一(yi)般使用兩三(san)年電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量(liang)衰減還剩80%不奇怪。
