不要整夜给手机充电了

Stop Charging Your Phone at Night, Here's Why

So your smartphone is effectively as MP3 player,
你的智能手机可用作MP3
portable gaming console, TV, and netbook
便携游戏机 电视和上网本
All in one small package.
一切尽在这个小仪器里
No wonder it needs a ton of energy to power up
难怪它需要大电量
So its battery better be good.
因此手机电池最好是可靠的
What can we do to make it last?
如何使电池续航更久呢
Certainly not charge it all night long.
当然不是整晚地给它充电
It’s a basic thing – you want your phone fully charged in the morning
当然 你想让手机在早晨充满电
so it’ll last through the entire day
这样当你离开舒适的家时
away from the comfort of your home.
它就能续航一整天
Been there, done that.
顺利完成工作
And even with cutting-edge smartphones that can charge to max capacity in a matter of one hour,
即使是能在一小时内充满电的新型智能机
there’s no guarantee that you’ll remember to charge it in the morning
也无法保证你会记得早上给它充电
while you’re in a sleepy daze.
特别是当你睡意沉沉时
Advice to leave your phone unplugged during the night
建议大家在夜间断开手机充电头
may seem risky and counterintuitive.
夜间充电危险且反常理
The worst fear here is that your phone will charge down while you sleep
最怕的是手机可能会在你睡觉时倒充
and won’t see the dawn of a new day
以致它无法像往常一样
to wake you up like you’re used to.
在黎明时分唤醒你
Frankly, it sounds like a horror story to me.
老实说 这听起来像个恐怖故事
But still, you can’t go against the word of science.
但你无法对抗科学常理
Leaving your smartphone on a charger is bad for it.
让手机一直连接充电器对手机不利
It’s bad for the battery’s lifespan.
这对电池寿命不好
Most modern devices use lithium-based batteries.
多数现代设备使用锂电池
Even though they’re rechargeable by nature,
即使它们天生能够反复充电
and made with this process in mind,
生产时也考虑到了这个过程
they’re highly vulnerable to constant interactions with high voltage of electricity,
但当它们接触到高压时也极其脆弱
like in the outlets of your house.
比如家用电源插座
Just imagine,
想象一下
if you’re leaving your phone on a charger overnight every night for a year,
如果你一年中每晚都给手机充电
it’ll spend more than 3 months total in contact with raw electricity.
它总共就会有三个多月的时间连接电源
This amount of stress on a battery will inevitably diminish its capacity.
这种电压量将不可避免地损害其容量
You’d be lucky if your smartphone lasted for a little over a year in this case.
这种情况下 如果你的手机能工作一年多点就是万幸
Thankfully, it’s not all that bad,
幸好 这还没那么糟
because manufacturers know about this issue
因为制造商知道了这个问题
and try their best to avoid the damage.
而且在尽全力避免这种损害
For example, there are automatic switches on your phone
比如 手机里装有自动切换器
that’ll stop the charging process the very moment it reaches 100%.
当电量达到100%时就会停止充电
It seems like that would solve the whole problem,
这看似能彻底解决问题
but it’s not that easy.
但并没这么简单
You see, when your phone naturally goes down to 99%,
试想 当手机电量自动降到99%时
the charging will start all over again.
它又开始充电
Your phone goes from 99 to 100 % charged, and back,
手机又从99%充到100%
many times during just one night,
整晚反复多次
and this too can degrade the battery.
这也容易损坏电池
Another thing you might take notice of is your phone charger.
另一个你可能留意的问题就是你的手机充电器
I know, they seem to be simple tiny plastic gimmicks
我知道 它们看起来只是种简单的小塑料制品
to convert energy from an outlet to a USB plug.
用于电源插座到USB接口间的能量传递
But if you pay close attention in a tech shop,
但如果你留意科技品商店
you’ll notice some of them cost a bit more than others.
就会注意到某些充电器比其它的要贵
Good, high-quality chargers have special chips in them
高品质充电器装有特殊芯片
that prevent overcharging.
能预防过度充电
So it’s advisable not to skimp on chargers,
因此建议大家不要在买充电器上省钱
this way you won’t spend much more money
这样你就不用在短期内花更多钱
on a new battery or entire smartphone too soon.
去买新电池或手机
And what about charging cables?
那么充电线呢?
They’re also not just pieces of wire, you know!
你知道 它们不仅仅是根电线
Cheap cables aren’t compatible with features like a Quick Charge,
便宜的充电线没有快充等功能
which is available on most modern devices in some form.
而多数现代设备在某种模式下都具备此功能
But in some cases, it’s worse than that:
有时 甚至会更糟:
a poorly manufactured cable could cause a short,
质量差的充电线可能会导致短路
and then your smartphone would be fried on a whim.
接着你的手机可能会随时燃起来
Oh, My order?
噢 我的订单?
Yes, I’d like fried smartphone, some fries with that, and a diet cola please…
是了 我要炸智能手机 搭配点薯条和健怡可乐
Overall, it’s always advisable to use good quality tech
总之 还是建议用质量好的科技产品
when it comes to something as expensive as smartphones these days.
特别是像如今的智能手机一样贵的产品
But even all these reinforcements combined
即使这些强化设备结合
can’t completely protect your smartphone
也无法完全保护你的手机
and allow you to charge it for as long as you want.
让你想充多久就充多久
These small charges and discharges between 99% and 100% will still occur,
在99%到100%间来回充电仍会发生
and the problem with them is that they’ll heat up your phone.
随之而来的问题是 这会使手机升温
Heat is bad for batteries.
而高温对电池不利
That’s why it’s so harmful for your phone
这就是盛夏把手机留在封闭小车里
if you leave it in a closed car in the middle of summer.
如此不利于手机的原因了
It’ll be all laggy and slow until you cool it down.
手机会因此变得反应滞后 迟缓 直到冷却下来
A battery left on the charge may produce heat,
充电中的电池可能会发热
but from the inside of the phone’s body,
但从手机内部来看
which is arguably even more destructive in the long term.
长期处于高温 它的受损会更严重
You can always ease this detrimental process
充电时取下手机壳
by taking your device out of the phone case when you’re charging it,
可以减轻此过程对手机的损害
but that won’t completely solve the problem.
但也不能完全解决这个问题
There’s also some other advice going around the internet
网上还有些其它建议
that I’ll have to disprove as myths,
我必须反驳 那都是荒诞的说法
and nothing more.
仅此而已
For example, you’ve probably heard something
比如 你可能听过
about fully depleting the charge of your smartphone
关于先耗尽手机电量
and then charging it to the maximum capacity.
再充到满电的说法
For the present-day, this advice is almost completely obsolete.
如今 这个建议几乎被彻底淘汰
This is fair for devices from the past decade,
对过去几十年产的手机 此说法是合理的
because they were using a different kind of batteries,
因为它们使用的电池种类不同
which were based on cadmium instead of lithium.
它们用的是铬电池而不是锂电池
These batteries had a real problem with memory.
那些电池真正的问题在于容量
Not that kind of memory.
不是常说的记忆容量
It was more like the amount of charge was memorized by the battery.
而是电池所能储存的电量
If it was charged to 30% regularly,
如果常常都充到电量的30%
it’d be easy to get it to that amount,
充到这个量就会很容易
but hard to charge beyond it.
但是很难继续充下去
Have you ever gotten so lazy you can’t even eat?
你是否曾懒到不能进食?
Are you kidding?
开什么玩笑?
Well, that’s kinda what was happening to those batteries.
好吧 电池大概也是这样
This effect was also called a lazy battery effect.
此效应也被称为惰性电池效应
Clever name, you think?
巧妙的名字 不是吗?
Any modern lithium-ion battery won’t get lazy like a cadmium based one,
任何现代锂电池都不会有像铬电池一样的惰性
so you don’t have to worry about that.
因此你不必为之担心
As is the case with the notion that the first charge should be a longer one,
如此例中的观点 第一次充电耗时更长
this is about cadmium batteries too,
这对铬电池同样适用
and based on the same problem I just mentioned.
原因和我刚才提到的一样
For a long time,
长期以来
there was little to no major breakthroughs in the ways we power our devices.
充电设备的发展少有重大突破
At least no sensible progress.
至少没有切合实际的发展
The power of batteries grew to accommodate our devices,
电池电量要适应设备需求
which needed more and more power,
就要存更多的电
but the sizes have decreased,
但由于手机尺寸变小
leaving less space to hold the battery.
留给电池的空间也更少了
So the advances in engineering new ways
因此 在研究生产电池的新方式上
to manufacture batteries haven’t stopped.
我们从未停止努力
Scientists and engineers promise that
科学家和工程师承诺
soon, we’ll have another kind of lithium-based battery
很快我们将有另一种锂电池
that’ll be able to charge in a matter of minutes and last for more than one day.
它可以充电数分钟 续航超一天
And that’s not the most insane new idea on the list.
并且这还不是已有的最疯狂的新想法
Can you predict what it might be?
你能猜出这是什么吗?
Tell me about the battery of your dreams in the comments.
请在评论区告诉我 你理想的电池是怎样的
But now let’s move on.
现在 我们继续刚才的解说
As you already know, wireless charging is a thing now,
如你所知 无线充电如今已经实现了
but it seems like scientists are ready to push it a step further.
但似乎科学家们还要进一步推进这项技术
One of their new ideas
他们的新想法之一
is to make battery chargers that can produce energy from a Wi-Fi signal.
是制造一种能用WiFi信号发电的充电器
The very thing that was making us spend the charge of our smartphones,
过去耗费手机电量的
will also charge them in the future!
也正是未来为手机供电的
And how about charging a phone with a sound?
如果能用声音给手机充电呢?
Using piezoelectric principles,
使用压电原理
tiny nanogenerators will be able to
微型纳米发电机将能
transform the surrounding sound to electric power.
把周围的环境声转换成电力
Even your own voice will be a good source of energy,
自己的声音甚至也能作上好的能量来源
charging a phone while talking on it?
在通话时为手机充电?
Yes, please!
是的!
Guess that’d be good news for service providers, huh.
对通信业务供应商而言 这可能也是个好消息吧
Scientists from Japan are in the middle of a decades-long study
日本科学家正处于长达数十年的研究中
that will allow replacing lithium ion batteries with sodium.
该研究致力于用钠电池替代锂电池
The main difference between those elements is that
这两种元素最大的不同在于
lithium is quite rare and expensive,
锂稀有且昂贵
while sodium is literally everywhere.
而钠基本上随处可见
It’s one of the most wide-spread elements on Earth!
它是地球上分布最广的元素之一
And batteries like that wouldn’t only be more efficient, but also cheaper.
而且这种电池不仅更高效 还更便宜
Another idea is to use literal sand in batteries.
另一种方法是在电池中使用所谓的“沙子”
Not quite literal though, as this battery will use silicon,
尽管并不是真沙而是硅
the main component of the sand.
它是沙的主要成分
Thinned down into nano-silicon structures,
细化到纳米硅结构
this element will be much more efficient in a battery
在电池中使用该元素
than the graphite that’s used now.
比现在用的石墨更高效
And now to more expensive stuff: how about gold batteries?
既然谈到更昂贵的材料:那么金制电池呢?
No, actually it’s nanotubes made of gold in batteries,
不 实际上它是电池中的金制纳米管道
where energy transfers through the gel will be so sturdy
能量能通过管道稳定传输
that the battery won’t ever degrade at all.
电池丝毫不会退化
With a battery like this one,
有了这样一块电池
you’d be able to charge your phone however and for as long as you like.
你就能用你喜欢的方式 给手机充电
But for now,
但现在
the best course of action is to use good quality charging equipment,
最佳操作方案是使用质量好的充电设备
keep your smartphone out of the heat,
让手机远离高温
and most importantly,
最重要的是
keep the charge in it between 30% and 90%.
使手机电量保持在30%到90%之间
Don’t starve it and don’t overcharge it,
不要过度耗电也不要过量充电
and your smartphone will serve you for years to come.
如此你的手机就能长期工作
Or until the new whizz-bang model
或者你可以等待
that you just have to have comes out!
你需要的新型一流充电模式出现
Hey, if you learned something new today,
嘿 如果你今天学到了新知识
