情態副詞

You've probably heard people say that you shouldn't leave your phone plugged in overnight.

你可能聽別人說過，不應該讓手機插著充電一整夜。

分詞構句

Doing so, depreciates your battery life and makes it age faster.

如果那樣做的話，你的電池壽命會降低並更快老化。

I always charge my phone overnight, and I always let it reach a full 100 percent charge.

我的手機總是充電一整晚，而且總是充滿 100%。

I can't live with this guilt, so I called up some battery experts to find the truth.

我無法與罪惡感共存，所以為了找出事實，我致電給幾位電池專家。

Daniel Steingart, Associate Professor at Princeton University told me that, actually ...

普林斯頓大學的副教授 Daniel Steingart 告訴我說，其實...

The easiest thing to do is just keep it plugged in all the time or as much as you can.

最簡單的方式就是將手機隨時插著電或是盡可能地插著電。

我再說一次：「盡可能插著電。」

The way he sees it is that we all need our phones ready and charged, so we might as well keep them fully charged forever.

他認為我們都需要手機隨時有電，如此一來，我們也希望手機可以永遠充飽電。

Your phone is pretty smart, and its software recognizes when it reaches full charge, so you can't technically overcharge your battery.

你的手機是非常聰明的，內建軟體會辨識出手機充飽電的時候，所以嚴格來說，手機的電池是不會過度充電的。

I also called Venkat Srinivasan, the director of the Argonne Collaborative Center for Energy Storage Science, and he told me ...

我也致電給阿貢合作中心能量儲存科學的部長 Venkat Srinivasan，他告訴我...

Don't charge the battery all the way to 100 percent.

Get it up to 90 percent and then stop it.

He never lets his phone reach a full charge, what?

他從來不讓他的手機充滿電，什麼？

He says we should keep our phones between 30 percent and 80 percent charged because once they reach 100%, certain reactions occur that degrade the electrolytes and depreciate our batteries.

他說我們應該讓手機的電量保持在 30-80%，因為一旦電量達到 100%，所引發的特定反應會降低電解液的靈敏度，以及損害電池。

So this is probably where that overcharging myth comes from.

所以這或許是過度充電迷思的起源。

Alright, so I went back to Dan, and I asked him to clarify.

所以我又回撥給 Dan，請他闡明他的看法。

And Dan told me that both of them are actually right.

而 Dan 告訴我，事實上他們兩個說的都是對的。

So, awesome, you do damage your battery when you charge it to 100 percent.

很棒，所以將電量充到 100% 確實會傷害電池。

But if you're going for the full charge already, keeping it there doesn't harm it.

但如果你已經將電量充飽了，一直插著電是不會傷害電池的。

Basically, if you are a normal human who just needs their phone out all the time, feel free to go to 100 percent and keep it plugged in forever.

基本上來說，如果你是出門在外隨時需要手機的一般人，那就盡情將電量充至 100%，並使手機維持在插著電的狀態。

But if you care a lot about your battery's life, like, a lot, a lot, or you don't use your phone that much, go Venkat's route and try to keep it in a narrow charging range.

但如果你很在乎電池的壽命，很在乎很在乎的話，或是你不常使用你的手機，那麼照著 Venkat 所說的做，試著將電量保持在一定的範圍內。

I admire your discipline, and maybe you'll extend your battery's lifespan.

我很佩服你的紀律，而且或許你可以延長手機電池的壽命。

Ultimately, though, batteries are meant to be used, and phones are meant to be used too.

最終，電池註定是要被使用的，手機也是注定要被使用的。

You don't do any damage by leaving it at 100.

你將手機充電充到 100% 是不會有害的。

You'll probably replace your phone before your battery totally dies.

在電池完全掛點前，你可能會先更換你的手機。

Or in a worst case scenario, you replace the battery.

最壞的情況可能會是，更換電池。

Go live your truth, keep it 100, goodbye.

活出真理，將電量充到 100%，掰掰。
