DONT： Burn out your battery

錯誤做法：耗光電量

You might be abusing your battery， especially if you have a habit of leaving the screen on， shutting down apps repeatedly or tossing it in your bag on a particularly frigid morning.

Smartphones are designed to keep apps open in the background. Forcibly closing them may satisfy that little part of your brain that wants to keep things neat and tidy， but because it takes more juice to start an app fresh than to wake it up， youre beating up on your battery every time you do it. Stop！

Avoid letting the temperature of your phone dip below 32 degrees Fahrenheit or soar above 95 degrees. In either case， damage can occur， lowering—in some cases， dramatically—the life of your battery.

如果你習慣讓手機屏幕一直亮著、頻繁地手動關閉應用或是在特別寒冷的早晨將手機帶到戶外，你可能正在傷害你的手機電池。

按照智能手機的設置，手機應用退出后會在后臺繼續(xù)運行。強行關閉應用也許會滿足你大腦對井然有序的渴望，但因為重新啟動應用比喚醒它要消耗更多電量，因此你每次關閉應用都是在損耗電池。所以不要再這么做了！

避免將手機置于32華氏度（0攝氏度）以下或95華氏度（35攝氏度）以上的環(huán)境中。這兩種情況都會損害你的電池，有時候甚至會極大地縮短電池壽命。

DO： Charge early and often

正確做法：盡早且經(jīng)常充電

Petri Hayrynen， senior product marketing manager of Global Smart Devices at HMD Global， said that charging your phone to 100% may seem like a good idea， but if youre using a high-voltage charger， it can put a strain on your battery. Instead， he said to pull the plug at 80%—90% for optimum usage.

“Old nickel-based batteries had a memory effect， which meant that if you didnt charge them from 1%—100%， they started to ‘forget their maximum capacity. As for the modern-day lithium batteries， the most stress is put on the battery when charging or discharging them fully; both reduce the charging cycles and overall battery life cycle，” Hayrynen said.

Hayrynen explained that people should do “more fast top-ups during the day，” versus charging smartphones overnight.

Try to keep the battery above 30% or so， letting it discharge occasionally to calibrate the sensors， and youll keep your battery healthier longer. To get the absolute fastest charge， toggle on Airplane Mode before plugging it in.

赫名迪全球智能設備部高級產(chǎn)品營銷經(jīng)理佩特里·海于呂寧說，將手機電量充到100%似乎是個好主意，但如果你用的是高壓充電器，反而會給電池帶來壓力。他說，應該在電量充至80%到90%時就拔掉插頭，這樣才能讓電池性能保持最優(yōu)。

海于呂寧說：“老式的鎳電池具有記憶效應，這意味著如果你不把電池從最低電量充到100%，鎳電池就會‘忘記自己的最高容量。而現(xiàn)代的鋰電池在完全充電和完全放電時受到的壓力最大，這兩種做法都會減少充電循環(huán)次數(shù)，從而縮短電池壽命?！?/p>

海于呂寧解釋道，人們應該“在白天多給智能手機快速充電”，而不是讓它充電一整夜。

盡量保持手機電量在30%以上，時不時地讓電池放電來校準傳感器，這樣能讓電池更長時間地保持更佳性能。如果想給手機快速充電，可以先調成飛行模式再插上充電器。
