手機的電量越來越少?
As mobile phone users, all we want is enough battery life to last the day.
作爲一個手機使用者，我們想要的僅僅是夠用一天的電量。Frustratingly, the older the device, the less power it seems to have.
但令人沮喪的是，設備越老，它的電量似乎就越小。In fact, the amount of battery life our mobiles have on any given day depends on two key factors: how we use them on that particular day, and how we used them in the past.
事實上，你的移動設備的總電量取決於兩個關鍵因素：你當天是怎麼用它的，以及你以前是怎麼用它的。
The ability of lithium-ion batteries to store charge depends on the extent of their degradation.
鋰離子電池儲存電量的能力，取決於它退化的程度。This means there is a link between how we handle our devices today and the charge capacity available in the future.
這意味着，我們今天使用設備的方式，關乎到它未來的儲電能力。Through a few simple steps, users can minimise this degradation and extend their device's life.
而只要簡單的幾個步驟，我們就能把（電池的）退化速度降到最低，並延長設備的壽命。Control battery discharge
有計劃地充電With most battery degradation occurring during deep discharge/charge cycles, it is actually better to limit the battery discharge during any one cycle before charging it again.
由於電池的退化過程大部分都發生在從超低電量到充滿電的過程中，所以，最好的做法就是避免電量過低。
Extend charging times
延長充電時間Many of today's mobile devices have a fast charge option that enables users to supercharge them in minutes rather than hours.
如今的很多移動設備都有快速充電的功能，它讓用戶能對設備進行“超充電”，讓整個過程只花幾分鐘，而不是幾小時。This is convenient when we're in a rush, but should be avoided otherwise.
在我們有急事的時候，這的確很方便，但我們應該避免這種行爲。Why? Because charging a battery too quickly reduces its storage capacity.
爲什麼？因爲充電太快會降低電池的總容量。Keep the temperature just right
保持溫度適宜Below 0°C, the amount of power available within the battery system is reduced.
在0℃以下，電池中可用的電量是會減少的。Above 45°C, the amount of power available is actually enhanced compared with lower temperatures, so you can get a little more "juice" from your battery under hotter conditions.
而在45℃以上，電池中可用的電量與溫度低時相比其實更多，所以你在炎熱的環境中能多撈到一些“油水”。However, at these temperatures the degradation of the battery is also greatly accelerated, so over an extended period of time its ability to store charge will be reduced.
但是，在這種溫度之下，電池的退化速度也會大大加快，所以長此以往它的儲電能力就會下降。Use battery-saving modes
實用電池保護模式Reduce screen brightness. The easiest way to conserve battery life while maintaining full function is to reduce the brightness of the screen.
調低屏幕亮度。想在保持設備正常運行的前提下保留電量，最簡單的方法就是調低屏幕亮度。Turn off the cellular network or limit talk time.
關閉蜂窩網絡，或者限制通話時間。The connection to the cellular network uses the global system for mobile communication (GSM) module.
連接蜂窩網絡會動用全球移動通信系統（GSM）模塊。The GSM is the most dominant energy-consuming component in a mobile phone,.
而GSM是手機中最主要的耗電組件。Use Wi-Fi, not 4G. With Wi-Fi being up to 40 percent less power-hungry than 4G for internet browsing.
用WiFi，不要用4G。用WiFi耗的電比用4G來得少，最多可以少40%。Turn on smart battery modes. All modern mobile devices have a smart battery saving mode (for instance, Android has Power Saving Mode and iOS has Low Power Mode).
使用智能電池模式。所有的現代移動設備都有智能電池模式（比如，安卓機有節電模式，而蘋果機有低電量模式）。
