不是說鋰電池不能完全放電的嗎?

的確唔可以完全放電, 但市面上一般手機都有避免完全放電既保護機制, 即實際電量去到5%左右時, 手機會顯示電量已經跌至0% (只係”顯示”為0%, 但實際電量還是5%) 然後自動關機

Any guidelines for maintenance of Lithium battery? I’d never heard of fully discharging the Lithium battery once every month to maintain its performance.

“Fully Discharge” can be found in Apple’s website. you can search it in the support page

Source please. Do they really say you have to ‘fully discharge’ the battery?

That’s what I get from the Apple site.
‘Extend Battery Life if Storing Your iPhone
If you will not be using your iPhone for a while, charge the battery up to 50 percent before storing it.’

From all other sites talking about Lithium battery in the universe say that Lithium battery should never be completely discharged? What makes the iPhone battery so special that it needs different maintenance approach?

我不能說第1點錯,但要不待機來換充電快一點,有點本末倒置,充電的原意不是要可以用多一些嗎。第2和第4點都是對的,不過真正的關鍵還是用一個電流較大的USB埠,就此而言,原裝充電機一定對,但電腦就要看情況,有些較舊的電腦要限電流,另外一般的USB hub,特別是不沒有外掛電源的,對手機充電會比較慢。

現在部分智能手機充電的電流要1.5A(如Sony Xperia Z),有部分USB埠會充得很慢甚至不能充電,請留意。

另外,第5點是錯的。這種放電的做法不適用於鋰電池,做得太多反而縮短其壽命。
