Apple 6S mobile phone charging feels a little numb and like leakage, what s going on?

First, the battery loss is large, and the number of cycles is high.

Many users reported that the iPhone battery drains quickly, and after testing, we found that a large part of the reason is due to the aging of the iPhone battery.

In a normal iPhone, when the battery cycle is around 400 500 times, the battery life will drop significantly. When you find that the number of battery cycles is too high, or the current total capacity is much lower than the design capacity, it means that your battery is wearing out badly, and you need to replace the battery to ensure normal use.

Second, the mobile phone has leakage.

Of course, the fast power consumption of the iPhone is not entirely a problem of the battery itself, I believe that many users have had a similar experience: obviously the battery has just been replaced, but the iPhone power consumption situation has not changed, which is likely to be the iPhone motherboard leakage.

In this case, the charger problem is normal.

The charger transmits the AC induced voltage to the motherboard of the mobile phone through the data cable, the grounding wire of the motherboard.

It is connected to the phone case, so the case will be charged, but the current is small, so it is a little numb, and the electric pen is used.

The measurement will light up. It's usually by design. The voltage of the power output to the earth is there, and the current is very small, so there is a tingling feeling. Leakage current of certified power supplies.

Meets safety requirements and does not cause substantial harm.

The specific reason is that in order to improve the external EMI (electromagnetic disturbance) of the power supply, a small capacitor is connected in series on the primary and secondary sides of the transformer to generate leakage current. It is also possible that the winding process of the transformer results in the parasitic capacitance of the primary secondary side.

Excessive size, up to hundreds of pf, can also lead to leakage current.

Other causes of electric shock:

1.The phone did not use the original charger.

2.There is no ground wire in the circuit plug. Because the mobile phone has a metal shell, when charging, the electricity and metal in the circuit have electromagnetic reflection, which makes the shell electrified.

But the fact that the Apple phone will be electrocuted while charging is a defect. But the back case of the phone is metal, and the metal frame will have static electricity. In addition, the iPhone charger is two jacks and there is no ground wire, so there will be a lot of induced current when charging.

Therefore, when charging static electricity, the reaction is stronger, and there will be no leakage and the like.

3.The numbness should be caused by a slight leakage of the phone.

It may be a non-isolated charger, it is not safe, do not use it again. The isolated charger will not be numb.

It has been used for a long time, and some of the electronic circuits or equipment in it have aged.

The mobile phone cannot be touched by the hand when the phone is charging and leaking.

Reasons for the feeling of electric shock when charging the iPhone:

1. The mobile phone does not use the original charger.

2. There is no grounding wire in the circuit plug, because the mobile phone has a metal capacitive shell, the electricity in the circuit and the metal are electromagnetically reflected during charging, so that the shell is electrified.

However, the feeling of electric shock when charging the Apple mobile phone is a defect, because the back shell of the mobile phone is metal, and the metal frame will have static electricity, plus the iphone charger is two jacks, and there is no ground wire, so there will be a large amount of induced current when charging, therefore, the reaction is stronger when static electricity, and there will be no leakage.

Let's see if there is a problem with the charger, a broken data cable, or the phone itself is a little worn out and has a severely broken screen.

Abnormal, this is a leakage phenomenon. In the case of stinging sensation in the charging of the Apple camera, it is a leakage phenomenon. You need to take the phone to the nearest official silver crack or go through the relevant repair inspection.

The iPhone 12 is the source of Apple's mobile phone product released at 10 a.m. Western Time (1 a.m. Beijing time on October 14, 2020) at ApplePark's headquarters. iPhone 12 Height: mm; Width:

Millimetre; Thickness: mm; Weight: 162 grams (oz) of Edge.

The iPhone 12 is designed with ionic glass, as well as an aluminum case for the 7000 series. The iPhone 12 has a straight bezel design and the back colors are: black, white, red, green, blue, and purple.

If there is a fault in the charging head, it is good to change the charging head, or take the charging head to after-sales. It may be that you have used a non-Apple original data cable or the charger has been used for a long time, or other reasons.

My phone is like this.,There's a slight numbness when I touch and slide it.,Changing a Xiaomi charger won't have this phenomenon.,It's not the problem of the positive and negative poles mentioned above.。 Now the charging head is mixed, and there are too many substandard products.

The charger has leakage, so change the charger.

The charger is leaking, try changing the charger.

Don't worry, mine is the same This is caused by the leakage current of the power adapter, plus Apple itself uses a metal frame It is normal to discharge a little bit and it will not cause harm to the body.
