iPod battery charging is controlled by the chip?

No, the connected power supply should display Charging, and if it is low, it will also show low battery

I guess your battery is dead.

Change the battery yourself 30 domestic ones.

First: iPods are generally full in about two hours.

Second: Don't wait until the battery is all used up before charging It's almost enough to charge it Third: Plugging it into the computer all the time won't affect The battery has a protective circuit and will automatically power off when it's fullFourth:

In addition, the iPod battery is different from the battery of ordinary mobile phones, it has no memory, and it does not need to be activated.

Whenever possible, you should try to use the AC adapter that comes with you to charge.

2. "The lithium battery of the new machine needs to be thoroughly charged 2 3 times for 12 hours": For lithium batteries, this is completely unnecessary. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel Zhipai cadmium and nickel-metal hydride).

So this statement can be said to be misinformation from the beginning. There is a big difference between the charging and discharging characteristics of lithium batteries and nickel batteries, and overcharging and over-discharging will cause great damage to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours.

3. The new battery must be "activated", but it does not need to be charged for a long time. In the use of lithium batteries, it should be noted that after a period of time, the battery will enter a dormant state, at which time the capacity is lower than the normal value, and the service time will be shortened. However, the lithium battery is easy to activate, as long as the bright and fierce eyes go through 3-5 normal charging and discharging cycles, the battery can be activated and the normal capacity can be restored.

Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user does not require special methods and equipment during the activation process.

4. In the process of using iPod, many friends will like to use NiMH batteries, waiting for the iPod to run out of power and automatically shut down before charging, which is also a wrong way to use. The correct way is to wait for the iPod battery icon to start flashing, and then we can charge it.

If we wait until the automatic shutdown, it is easy to cause the iPod0 lithium battery to be over-discharged, and in the long run, we can see that the capacity of the battery will be reduced very quickly, and the recoverable capacity may not reach the nominal 500 times after each full charge, which is something we must avoid. Because this is the problem caused by incorrect use, not the quality of the iPod battery, we may not get the normal warranty of the iPod and have to spend extra money to replace the battery.
