Apple iphone Lithium battery charging considerations

The iphone's battery is lithium, but now the concept of a lot of battery maintenance on the Internet is based on the Ni-MH battery, and the iphone battery can be said to be farfetched, the following small series to explain a few about the iphone battery maintenance concept.

iphone Lithium Battery Charging considerations

Battery sleep

If the iphone is not used for a long time, the lithium battery will go into hibernation after a period of time, and the capacity of the lithium battery will be greatly reduced in the dormant state. However, the iphone's battery is very easy to activate, because the lithium battery itself has little memory effect, so as long as after 3-5 normal charge and discharge cycle can activate the battery, restore normal capacity.

So if it's a new iphone, or an iphone that hasn't been used for a long time, you don't have to take any special steps to activate the iphone, just charge it naturally.

Charge activation

For lithium Battery "activation" problem, a lot of saying is: Charging time must be more than 12 hours, repeatedly done three times, in order to activate the battery. The claim that "the first three charges are more than 12 hours" is clearly a continuation of nickel batteries, such as nickel cadmium and nickel hydride. So this argument, it can be said that the beginning is misinformation.

Excessive charge

Lithium battery cell phone or charger will automatically stop filling after the battery is full, there is no NI electric charger called "trickle" charge for 10 hours. In other words, if your lithium battery is filled, it is also a white charge on the charger.

1. Please use the original or reputation of a better brand charger, lithium batteries to use lithium battery charger, and follow the instructions, otherwise damage the battery, or even dangerous.

2. Not more than 24 hours of time.

3. Charging, as far as possible slow charge, reduce the fast charging mode.

4. New battery purchase or long time unused, before using the battery to flush foot.

5. The battery after 35 times full charge and discharge cycle of its internal chemical substances will be fully activated to achieve the best use of the effect.

6. Before charging, Ni-MH batteries and lithium batteries do not require special discharge, improper discharge, but will damage the battery.

7. Cell phone batteries are self discharge, ni-MH battery every day will be the remaining 1% or so discharge. Lithium-ion batteries are discharged daily by 0.2%~0.3#.

How to maintain the iphone battery

1, the iphone using lithium polymer batteries, there is no memory effect, so absolutely do not need to charge and discharge every time thoroughly (that is, you want to charge at any time).

2, lithium battery after each charge and discharge cycle, the electricity will reduce a little, about 400 times after the charge and discharge cycle will be reduced to 80%. The so-called one-charge cycle is full and light, that is, if you use 20% of the electricity is full, to

Repeat 5 times to calculate a charge and discharge cycle.

3, because the battery has a chip to calculate the electricity, in order to calibrate, should do a full monthly playback power (that is, completely full after the use of no electricity).

4, as long as the use of Apple's official power, full will become a direct use of power mode, there is no overcharge problem.

5, lithium battery charging process is the first 80% use a quick charge 2 hours to complete, after 20% using continuous recharge charge also to 2 hours. This is normal, do not have to do anything special.

So summed up, the iphone's battery maintenance is very simple, in addition to the introduction of the power-saving considerations, you just do a monthly calibration, as far as possible to use electrical wiring (such as in the office), there is no other considerations. It should be misunderstood what should be prevented from being recharged, often filled (or often not filled).

In general, the iphone's overcharge protection circuitry makes the iphone sit still, but none of us can guarantee that the battery's charge-and-discharge protection circuitry will never change and the quality is foolproof, and if your iphone has been in use for a long time, this excess charge will keep the battery on the brink of danger. So, we'd better not charge too much on a regular basis.
