How to charge a smartphone to optimise the battery life

I’ve been wondering why my iPhone battery drains so fast as It dies on me quite often. My friend said it had to do with my incorrect charging patterns. My friend said I should charge my phone when the battery’s about 20% rather than when it’s almost empty or rather full at 80 or 90%. And a battery needs to be fully charged to 100%. This sounds plausible and may be the common practice of most people. But a little research on the Internet just revealed that most of us, or at least my friend and I, do charge our phones wrong.

According to several websites, charging a phone from a low battery level (under 20%) to 100% in one go is one of the practices that shorten the battery lifespan because “a high voltage stresses the battery”. It turns out that charging a phone battery several times throughout the day from around 30~50% to 80% is most desirable. That means several short charging sessions a day rather than a long heavy one optimises the battery performance. So should I start charging my phone bit by bit whenever I can? Let me try and see how it goes.


如何正確充電延長手機電池壽命?

我的智能手機電池耗電速度很快,我一直對此困惑不解,朋友說那是因為我充電的方法不正確,我應該在手機電量20%左右時充電,而不是像我平時般到差不到沒電了或還有80至90%電時充電,而且每次充電都應該充滿至100%。這聽來很合理,很多人甚至奉為金科玉律,是否真的如此?我在網上做了點資料搜集,發現許多人都不會為手機正確充電。

根據網上資訊,如果從低電量(如少於20%)起不中斷替手機充滿至100%,容易對手機的電池造成壓力,反而縮短電池的壽命。而正確的充電方法應是在電池30到50%左右時充電至80%,並不需要充滿,這才不會對電池造成壓力,從而延長電池壽命。這與大部人的充電習慣大相徑庭,且讓我嘗試這個「正確方法」看看能否讓電池變得更耐用。

  1. Batteries have a short life – 2 years max – no matter how you use it. Just replace it or buy a new phone. The iphone is designed to last only for 2 years.
