What is the reason why the phone is hot when the Apple 5 phone is charging?

When the phone is charging, you don't play with the phone, the normal charging is a bit hot, and it is normal.

The reason for the battery heating: the power consumption of the mobile phone in standby is very small, that is to say, the equivalent load resistance of the battery is large, so the discharge current is very small, so the battery will not heat up, and the internal consumption of battery power is very small. The power consumption of the mobile phone when it is ready to talk or use *** is very large, that is to say, the equivalent load resistance of its battery is small, and it is discharged with a high current when working.

After the battery discharges a part of the electricity, the internal resistance increases, but the current required for the work of the mobile phone can not be reduced, then, a considerable part of the energy is consumed on the internal resistance of the battery, resulting in the battery heating, the discharge accelerates, and the battery service time is also shortened very quickly. Recommendations: 1

It is normal for the phone to generate no more than 60 at normal room temperature, and the battery will not be damaged. 2.It is not advisable to use a high-current charger for too long, as charging for too long will damage the battery and generate heat.

3.It is best to use the charger in an original or quality reputable product. 4.

If you are not in a hurry to use it, it is recommended to charge it with a seat charger (slow charging mode) to avoid heating the battery5If you feel that the phone is a little hot when using the phone to listen to *** or battery charging, if it exceeds 60, immediately return to the standby state or change the battery, and unplug the charger immediately if it is charging.

Switch to a low-current charging head, or charge it on your computer.

First, the charger problem. Second, it is the quality of the mobile phone itself.

Normal, my iPad charging is also a bit hot.

It is very likely that the heating of the fuselage is caused by the long charging time. Generally, when the remaining power of the iPhone is about 15-10%, the charging time takes 4 hours, and the maximum time will not exceed 5 hours. Try not to leave your phone plugged into the charger for a long time, which will affect the battery life very much.

Charging precautions].

For Apple mobile phone users, the service life of the battery is one of the more concerned issues, if you want to make the battery have a long service life, you have to learn about some tips about charging Apple mobile phones.

1. Don't rush to charge the new device before using it.

When you buy a new Apple device, don't rush to charge it, use it normally until it has 10% of the remaining power, and then turn it off and charge it. It is best not to run out of battery power, because the new lithium-ion polymer battery is different from the old battery and has no memory effect.

2. The data cable is connected to the mobile phone first, and then the socket is missing.

When charging, you should connect the cable to your Apple device before plugging the adapter into an outlet. The new device can be fully charged in about 4 hours after the first use of the remaining 10% of the charge, so users can take care not to charge it for too long.

3. Charge at normal temperature.

Charging your phone while playing, putting it under your pillow to charge, or charging it in direct sunlight can easily make your phone hot, thus reducing the life of your phone. The battery of the iPhone is used and stored at a temperature between 0 degrees and 22 degrees Celsius, and the temperature suitable for charging is between 10 degrees and 35 degrees Celsius. Sub-zero degrees will cause the iPhone to charge abnormally slowly or not charge, and temperatures of 35 degrees and above will seriously reduce the effective capacity of the battery, greatly reducing the life of the battery.

4. How to tell if the charging is fully charged when the power is off.

Apple users should know that there will be a green battery icon in the middle of the screen when the phone is turned off and charging. When charging, there will be a lightning-like sign underneath the battery, and when it is fully charged, the lightning-like sign will disappear. In order to prevent overshoot, when the battery is fully charged, a part of the charge will be automatically released, and there will also be a lightning bolt sign at this time.

5. Do not pull the cord immediately after the battery is fully charged.

When the battery is fully charged, do not unplug the adapter or cable immediately. Press the power button for a while, the screen will quickly flash the pattern when charging, and then the white apple logo will appear until it is turned on normally. Finally, unplug the adapter and cable in order.

It is normal for the mobile phone to heat up when the Apple mobile phone is charging, check whether the mobile phone charger does not meet the rated voltage of the Apple mobile phone, the mobile phone charging current is too large and the mobile phone battery capacity is less than 60%, it will be hot when charging, replace the charger and battery in time.

The Apple mobile phone has a self-adjustment function when charging, so you don't need to worry about the charging time being too long, and the system will automatically control the slow charging when charging in the middle of the night.

During the charging process of the mobile phone, there is a resistance working in the power circuit when it is running, and the resistance and current are playing with each other, and the heating is inevitable, and it is mainly concentrated in the battery and the internal PCB motherboard.

In the winter when the ambient temperature is not high, mobile phone charging may rarely cause the mobile phone to be hot, but in the hot summer, due to the increase in ambient temperature, coupled with the heating generated by internal charging during charging, because the difference between the internal temperature and the ambient temperature is not large enough, resulting in a decrease in heat dissipation efficiency, it will naturally lead to the hot mobile phone.

Tips for phone charging to protect the battery:

1. The charging time is 3-4 hours.

The charging time should not be too long, it can be fully charged, and the battery life will be seriously affected for a long time, and even danger will occur.

2. The first charge does not need to be too long.

The first charge does not need to be fully charged for 12 hours, which is what the old nickel-metal hydride batteries only need to do, and the current batteries are lithium batteries or polymer lithium batteries, and the first time it can be charged the same as usual.

3. Do not use photoelectric completely.

Running out of power on your phone can have a serious impact on battery life.

4. Charge when powered off and charged in airplane mode.

When you need to charge urgently, turning off your phone is the fastest way to charge it. In addition, we can also put the mobile phone into airplane mode to cut off the synchronization of data and improve the charging efficiency.

Summary. Why is the Apple phone hot when charging, and it is normal for the charger to be slightly hot when the Apple phone is charging. Because everyone's feeling is not the same, as long as it is the original Apple mobile phone charger, no matter how it is charged, it is fine at room temperature, and it will not affect the mobile phone and the charger The reason is that the charging head will also generate a large amount of heat when charging, and there will be a slight heating, and the surface temperature will not exceed 50 degrees under normal circumstances.

There is a high-frequency transformer in the mobile phone charger, which converts the pulsating voltage generated by the switch tube, which is very small, but the working frequency is very high, and it can reach tens of kiloheses, so the heat is very large, and there are some integrated blocks, which will also heat up as long as it is not too hot, it can be used. Extended information: The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery.

After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle. Generally, it is charged with DC current (also with asymmetric AC current or pulse current). In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or a combination of these methods.

The reasons why the charging of the Apple mobile phone is very hot are:1. It is normal for the iPhone to heat up with a smile when charging, especially when using 20W and 30W fast charging.

2. It will heat up when charging with a non-original charger.

3. When charging, you are still using the hand regret ascending machine, such as playing games, playing **, etc.

4. If you open a lot of programs in the background, it may also cause the phone to heat up.

5. The protective case of the mobile phone hinders heat dissipation.

Phone Charging Tips:

1. If the newly bought mobile phone battery is a nickel-metal hydride battery, then the first 3-5 charges are generally called the adjustment period, and it should be charged for more than 14 hours to ensure that the activity of the nickel-metal hydride battery is fully activated. Lithium-ion batteries do not have a memory effect, but they have a strong instinctive nature, and should be fully activated in order to ensure that the best performance can be achieved in the future.

2. Some automated smart fast chargers only indicate that they are 90% full when the indicator light changes. The charger will automatically change to fully charge the battery with slow charging. It is best to use it after the battery is fully charged, otherwise it will shorten the use time.

3. Before charging, the lithium battery does not need to be discharged, and improper discharge will damage the battery.

4. Try to charge slowly when charging, and reduce the fast charging mode; Do not exceed 24 hours.
