After a period of use of the phone, I suddenly found that the battery has become very unpleasant, and my friend's ring has no electricity at all. What's going on?
手机用了一段时间之后，突然发现电池变得非常不耐用，刷会儿朋友圈就没电了，怎么回事？

In fact, charging batteries to 100%, charging all night, completely consuming electricity and then charging and other common practices will shorten the battery life of the phone.
事实上，将电量充到100%、整晚充电、完全耗光电量后再充电等常见做法都会缩短手机电池使用寿命。

Let's take a look at several major errors on the phone charging and the right way to charge it.
一起来看看关于手机充电的几大误区和正确的充电方法吧。

The best way to charge your phone is a little at a time, whenever you have a chance.
最好的充电方法是一有机会就给手机充一点电。

You can put the power when plugged in, even if it is a few minutes.
可以充电的时候就把电源插上，即使是几分钟也行。

According to the Battery University website, "Partial charges do not harm the battery."
据电池大学网站称：“部分充电(partial charges)不会对电池造成损害。”

Don't fully discharge your phone before plugging it in.
不要在耗光手机电量后再充电。

Battery University says that so-called deep discharges – which happen when you use your phone until only a small portion of its battery life is left — wear down batteries.
电池大学网站称，所谓的深度放电，即将手机电量消耗到仅剩一小部分，会损耗电池。

Try to keep battery power between 65% and 75%.
尽量使电池的电量维持在65%到75%之间。

According to the Battery University website, the lifespan is the longest when the battery life of your smartphone lithium-ion batteries is between 65% and 75%.
据电池大学网站称，你的智能手机锂电池(lithium-ion batteries)的电量始终维持在65%至75%之间时，寿命(lifespan)是最长的。

It's clearly impractical to always keep your phone charge between those levels, but at least you know what's ideal!
要想让手机电量始终保持在这个水平显然是不切实际的，但至少你知道什么是理想水平！

If you can't do that, shoot for keeping its charge level between 45% and 75%.
如果你不能做到这一点，那就争取将电量保持在45%至75%之间。

The second best charge range for batteries inside smartphones is between 45% and 75%. That's probably a lot more realistic for most people on a day-to-day basis.
智能手机电池第二理想的电量范围在45%至75%之间。对于大多数人来说，这在日常生活中可能更为现实。

But you do have some wiggle room. If you typically keep your phone's charge level between 25% and 75%, you likely won't cause too much long-term damage.
但你的确还有回旋余地。如果你通常将手机电量保持在25%至75%之间，那么也可能不会造成太多长期损耗。

Never fully charge your battery — and particularly not from a low charge level.
不要完全充电，特别是在电量很低时。

Fully charged phone batteries less than 25% of the capacity will reduce the battery capacity and shorten its service life.
将电量低于25%的手机电池完全充满会降低电池容量，缩短其使用寿命。

In fact, charging from pretty much any amount to 100% is a bad idea. According to Battery University, lithium-ion batteries do "not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery" and wears it out in the long run.
事实上，无论手机剩余电量是多少，将电量充满都是不明智的。据电池大学表示，锂电池“不需要完全充电，也不应该完全充电。事实上，最好不要完全充电，因为高压会给电池施加压力”，从长远来看会对其造成损耗。

You likely shouldn't charge your phone overnight.
或许你不应该整晚都给手机充着电。

I've seen a lot of debate about the effects of charging your smartphone overnight. But if charging to 100% causes the most damage to a phone battery's lifespan, you should probably cut it out.
关于整晚给手机充电的影响存在很多争议。但是如果将电量充满对手机电池的寿命伤害最大，那么你或许不应该继续这样做了。
