Charger how to charge?

Hundreds in recent years can be said to be discussing this question not greasy topic, regardless of the Internet there is no amount of teaching, and no amount of instruction, members of the public can always heard a lot of "wrong" mobile phone charging instruction. These "mobile first to fill eight hours with", "mobile phones to full use no electricity to use" and "charge a cellphone to 90% to unplug charger" Ugh Ugh

Teaching not only charging for these errors appear in the phone lines, electrical stores, Apple store, even the teaching of TV news has a similar charge. Charger how to charge and the phone battery how to maintain it? For today we get our phone charge must know three things, as long as you follow the instructions on the three electrical charge, you can make your cell phone battery has a longer life expectancy than others Oh!

Note: sources include Apple's official website, the battery manufacturer's instructions, and after my own years of validation. Currently my personal 2010 first generation iPad, 2011 iPhone 4S are still has almost 80% storage battery, no battery has been replaced, these instructions are effective!

A, lithium batteries have no memory effect and excessive discharge will speed up killing him

According to my personal experience, the "mobile phone recharging electricity runs out" can be said to be first place in the ranking of the misconceptions. Why there is this idea? "Batteries have memory effect if not finished charging battery broken" it is characteristic of Ni-MH rechargeable batteries and lithium-ion batteries are widely used in mainstream before charging the battery (pictured third rechargeable battery) does have to be battery runs out before they can charge, otherwise the battery power will be less.

But now, smart phones, tablets, laptops, digital cameras, power supplies and other products used is commonly known as the "lithium battery" Li-Polymer battery. This battery with Ni-MH battery very different characteristics: no memory effect, not excessive discharge. Lithium polymer battery life calculation based on "charging cycle", or "0~100%" charging times.

Simply put, if a lithium-ion batteries has 1000 cycles life expectancy, so in theory, as long as "from 100% to 0% from charging back to 100%" this repeat 1000 times, then the batteries almost died! But in fact the physical properties of lithium-ion batteries resulting in excessive discharge can damage the battery itself, if you often use 0% battery charging, the batteries wouldn't have you ever used so repeatedly and directly killed early!

So the first use of lithium-ion batteries to limit was never uses no electricity to charge batteries, preferably when you can charge it to full battery, so that the battery can make you long for Hello! If you often go out all day is no way to recharge, 10% left often drag home, battery charging, then you might consider buying a power of action with you, do not always make your battery in ultra low power state well!

Second, charging full don't pull, leave unplugged

Charge ranks second in the misconception is "charge charging to 100% immediately pulled out." The origin of this saying I don't know, but we do not need to go into the wrong idea comes from. In fact, whether it be cell phones, or computers, the companies overcharge prevention mechanism is designed, when the battery is full, it will automatically switch to power supply to supply computer or mobile phone power, such as can be seen above, when the computer battery charging to 100% on MacBook Pro automatically switches to power supply until the battery is down to 95% will be able to sustain this state before. And if you pay attention to the iOS6 (if you have it in the baby in the baby) at the rear right corner on full charge the battery indicator will turn into plug pattern, which is a cell phone tips for using an external power supply the power supply.

So charging full does not need to rush to unplug the power, wait when you want to leave the place where you can recharge and can be pulled out. Perhaps someone will question "has been stuck in really all right? "Ugh-I think about this unless you put the charger plug is for a week, please believe that electronics makers for overcharge prevention ability of mechanism design, don't make yourself nervous!

A two or three week let your battery 40% time, maintaining battery health

After the read instruction if you successfully change your charging habits, and in accordance with the above instructions to protect the battery, your battery "battery longevity" has already made a big step forward Hello! But you also need to do something here: 40% once per two week let your battery to maintain the battery's health. First of all we want to know, is a nagging battery lithium-ion batteries, you keep him charging and discharging him early points, kept his discharge to 0% points early, even you have been discharged early are not hanging up!

Lithium-ion batteries because of their physical characteristics, makes for a long time not to do full discharge, activation of internal storage structure, will make the batteries dying early. But if you make every day he has been discharged, would also let the battery dying, so in order to solve this problem, the best way is to let the battery every two weeks is less than 40% (30%, not 0%) charge after charging, you can better sustain cell health, makes him long to accompany you!

Of course, this mainly you often stuck do not pull the electrical demand, if you discharge the battery every day to less than 40%, then you don't have to do this another thing now!

Battery-to what extent is "dead"? Simple two steps out first lithium-ion batteries after the dead would be expanded as indicated in figure, please note that this is not explosive, mechanism for this is just to remind you the battery has gone bad, iPhone or other device if you suddenly "get fat", please go to change the batteries! Second, if the battery is not getting fat, but your phone is significantly less storage power than ever before, so if you're excluded not because of sharply after electricity is still your App soon out of power, suggest that you quickly repaired Hello!
