Lithium-ion batteries, like those in iPhones, have a longer usable life if you don’t charge above 80%. But, to last the day, you probably want a full charge. With iOS 13, Apple may give you the best of both worlds.
如果您的充电量不超过80％，则锂离子电池(如iPhone中的电池)的使用寿命更长。 但是，直到最后一天，您可能想要完全充电。 借助iOS 13，Apple可能会给您带来两全其美的体验。
Apple announced iOS 13 at WWDC 2019. Buried in the list of extra features was a note about “battery optimization.” Apple says it will be “reducing the time your iPhone spends fully charged.” Specifically, Apple will prevent your iPhone from charging above 80% until you need it.
苹果宣布iOS的13在2019年WWDC埋在额外的功能列表是一个关于笔记“电池优化”。 苹果表示，这将“减少iPhone充满电的时间。” 具体来说，苹果会阻止您的iPhone充电至80％以上，直到您需要为止。
You might be wondering why Apple wants to keep your iPhone at 80% charge. It’s all about the way Lithium-ion battery technology works.
您可能想知道苹果为什么要让您的iPhone保持80％的电量。 一切都与锂离子电池技术的运作方式有关。

Batteries, in general, are complicated technology. The fundamental goal is to cram as much energy as possible into a small a space as possible, then safely release that energy without causing a fire or explosion. It’s a juggling act of priorities.
通常，电池是复杂的技术。 基本目标是将尽可能多的能量塞入尽可能小的空间，然后安全释放该能量而不会引起火灾或爆炸。 这是优先事项的杂耍。
Lithium-ion batteries make things extra complicated by being rechargeable. Earlier rechargeable technology suffered from the memory effect—essentially, batteries lost track of their maximum capacities if you constantly recharged them after only partially discharging them. Lithium-ion batteries don’t have that problem. If you’re still draining your battery to empty before recharging it, you should stop. You’re damaging your battery’s health.
锂离子电池可充电，使事情变得更加复杂。 较早的可充电技术会遭受记忆效应的影响—本质上，如果仅在部分放电后不断对其充电，则电池将无法跟踪其最大容量。 锂离子电池没有这个问题。 如果仍在为电池充电之前耗尽电池电量， 则应停止 。 您正在损害电池的健康。
One cycle consists of depleting an amount that adds to 100%. Apple 一个周期包括消耗增加到100％的数量。 苹果
Lithium-ion batteries charge to 80% faster than previous battery technologies did. For most people, 80% is enough to make it through the rest of the day, so it gives you what you need sooner. It also doesn’t have the dreaded “memory effect” that causes the battery to lose track of its full capacity.
锂离子电池的充电速度比以前的电池技术快80％。 对于大多数人来说，一天中剩下的80％就足够了，因此它可以尽快为您提供所需的东西。 它也没有令人恐惧的“记忆效应”，该效应会导致电池失去对全部容量的跟踪。
However, instead of having a memory issue, Li-ion has a maximum charge cycle issue. You can only recharge the battery so many times, and then it starts to lose capacity. It’s not merely charging zero to 100% that counts as a full charge. If you charge from 80 to 100% five days in a row, those 20% charges add up to one “full charge cycle.”
但是，锂离子电池没有最大的充电周期问题，而没有存储问题。 您只能给电池充电很多次，然后开始失去容量。 不仅仅是将零到100％的电量算作是充满电。 如果您连续五天从80％充电到100％，则这20％的费用总计为一个“完整充电周期”。
Not only does draining the battery to zero and then charging to 100% hurt your battery in the long run, always charging the battery isn’t good for it either. By staying near 100%, you risk overheating the battery (which can cause damage). Additionally, to prevent your battery from “overcharging,” it stops the charge for a while, then starts again.
从长远来看，将电池电量消耗至零，然后再充电至100％不仅会损害电池，而且始终给电池充电也不利。 保持在100％附近，可能会导致电池过热(可能导致损坏)。 此外，为防止电池“过度充电”，它会暂时停止充电，然后重新开始。
That means if you charge your device overnight after it hits 100%, it drops to 98 or 95%, then charges back up to 100%, and repeats the cycle. You’re using your maximum charge cycles without even actively using the phone.
这意味着，如果您在设备达到100％后为它充电一整夜，它会降至98％或95％，然后再恢复到100％，然后重复该循环。 您正在使用最大充电周期，甚至没有积极使用手机。
For all these reasons and more, most battery manufacturers will recommend the “40-80 rule” for lithium-ion. The rule is straight forward: try not to let your phone deplete too much (less than 40%), which can damage the battery, and try not to keep your phone charged entirely (more than 80%) all the time.
由于所有这些原因以及更多原因，大多数电池制造商会建议锂离子使用“ 40-80规则”。 规则很简单：不要让手机的电量过度消耗(少于40％)，这会损坏电池，也不要一直保持手机完全充电(超过80％)。
Either scenario is made worse by weather, so if you want your battery to retain its full capacity longer, keep it around 80%.
两种情况都会因天气而变得更糟，因此，如果您希望电池将其全部容量保持更长的时间，请将其保持在80％左右。
Recent iOS updates include a battery health feature the let you check on your battery capacity, and see a history of your battery usage. The feature is a useful way to know if you’ve stuck to the 40-80 rule.
iOS的最新更新包括电池运行状况功能 ，可让您检查电池容量并查看电池使用情况的历史记录。 该功能是了解您是否遵守40-80规则的有用方法。
But Apple knows you don’t want to start the day around 80%. If you travel a lot or otherwise find yourself frequently out of reach from an outlet, that extra 20% can easily be the difference in whether your iPhone makes it to the end of the day. Staying at 80% risks losing a valuable asset, your phone. That’s why the company wants to meet you in the middle.
但是苹果知道您不想在80％左右开始新的一天。 如果您经常出差，或者经常发现自己无法到达商店，那额外的20％可能很容易成为您的iPhone是否可以使用到一天结束的区别。 保持80％的风险会丢失您的手机，这是一笔宝贵的资产。 这就是为什么公司希望在中间与您会面。
In iOS 13, a new charging algorithm will keep your iPhone at 80% when charging overnight. That algorithm will determine when you typically wake up and start the day, and restart the charging sequence to give you fully charged battery when you wake up.
在iOS 13中，一种新的充电算法可在一夜之间为您的iPhone保持80％的电量。 该算法将确定您通常在什么时候醒来并开始新的一天，并重新开始充电顺序以使您在醒来时充满电。
That means your iPhone won’t spend the entire night taking a charge it doesn’t need (and risk overheating), but when you start your day, you should have 100% battery charge. It’s the best of both worlds to give you as long as battery life as possible, both in retaining the full capacity of the battery and making it through the day.
这意味着您的iPhone不会整夜都在充电，不需要充电(并且有过热的危险)，但是当您开始新的一天时，应该为电池充电100％。 保留电池的全部电量并全天候工作，这是两全其美的做法，即尽可能延长电池寿命。
