1. Has your iPhone ever dropped to one percent and then stayed there without turning off for a suspiciously long time? Well, there’s a reason for this. And it isn’t limited to iPhones, virtually any rechargeable device can experience this behavior, which results from battery capacity being really difficult to measure. 2. You see, batteries aren’t like gas tanks, where the energy remaining can be physically measured by volume. Instead, voltage output, or electrical pressure, is used as the main metric for calculating capacity. The challenge is interpreting the voltage level as a percentage of remaining battery. 3. So even though companies like Apple create complex algorithms to calculate remaining battery, they aren’t perfect. In fact, they tend to underestimate how much battery is left just in case. That’s why it might seem like your iPhone drops faster from 100 to 90 percent than 30 to 20 percent. 你的 iPhone 电量是否曾经下降到1%,然后在那里停留了令人生疑的相当长的一段时间没有关机?嗯,这是有原因的。而且这并不局限于 iPhone,几乎任何可充电设备都会出现这种现象,这是因为电池容量真的很难测量。 你看,电池不像油箱,剩余的能量可以通过体积进行物理测量。相反,电压输出,或电子压力,被用作计算容量的主要指标。挑战在于将电压水平转化为剩余电量的百分比。 因此,即使像苹果这样的公司创造了复杂的算法来计算剩余电量,但它们并不完美。事实上,为了以防万一,他们往往会低估剩余电池的容量。这就是为什么你的 iPhone 从100%到90%的下降速度看起来比从30%到20%的下降速度快。
