How big is the consequence of a leak on the motherboard of a mobile phone

Leaking power from your phone will increase battery drain, which in turn will affect battery life! Leakage is generally when the motherboard is welded together, two or more contacts are welded together, resulting in excessive current, although the voltage has not changed much, it can still be used, but the power of the capacitor or all levels of the tube has increased, and the mobile phone will feel very hot after playing for a long time! Sooner or later, the motherboard will burn one day, it is recommended that you change the motherboard, but see if it is suitable!

There are several situations of leakage from the motherboard of the mobile phone:

1.Leakage of the main power supply system: a

Before the battery voltage enters the power module of the motherboard, there are several groups of large capacitors with grounding filter, and if any capacitor is short-circuited, there will be obvious leakage; b.Changes in the capacitance of the one or two electrolytic capacitors that supply power to the power amplifier module will also cause significant leakage; c.There is a short circuit in some lines of the power module; d.

A short circuit occurs in the vibrating rod circuit; The line is abnormal.

2.Leakage of other power supply systems: This situation occurs after the start-up, and other circuits such as Bluetooth, intermediate frequency, multi-**, display and other lines have a certain resistance, capacitance or chip parameters change or short circuit, which is not easy to find the fault point.

Generally, the leakage of the mobile phone motherboard mainly occurs after the mobile phone is liquid, or in a humid and dirty environment for a long time, the first situation can be powered by the regulated power supply for the mobile phone, and the current can be known by checking the current situation without turning on the phone, and the second situation needs to be started normally after the mobile phone is turned on, observe the current change, and then observe the current situation in the standby state after turning off the keyboard and screen display to make a judgment.

It is easy to burn out the body......And once the electricity leaks, even if your board is fully charged, it will be completely out of ...... in less than five minutesBeg.

If you want to judge whether the motherboard of the mobile phone is leaking, you can see whether the mobile phone is heating for a long time when playing games. Generally, mobile phones consume power very quickly, and they will heat up after using them for a period of time, that is, there is leakage.

Generally, the leakage of the motherboard of the mobile phone mainly occurs after the mobile phone enters the water, or it is in a humid and dirty environment for a long time, the first situation can be powered by the regulated power supply for the mobile phone, and the current situation can be known by checking the current situation without turning it on, and the second situation needs to start the mobile phone normally after booting up, observe the current change, and then observe the current situation in the standby state after turning off the keyboard and screen display to make a judgment.

The leakage of the mobile phone motherboard may be the leakage of the main power supply system, there are several groups of grounding filter large capacitors before the battery voltage enters the motherboard power module, and any one of the capacitors will be short-circuited, there will be obvious leakage, or it may be that the battery voltage for the power amplifier module to supply power to the power amplifier module The change of one or two electrolytic capacitance values will also cause obvious leakage, or it may be that some lines of the power module have short circuits, vibrating rod circuits have short circuits, and abnormal CPU lines may also lead to leakage of the mobile phone motherboard.

Summary. How to tell if there is leakage on the motherboard of the mobile phone Hello dear, <>

The method of judging whether there is leakage on the motherboard of the mobile phone is as follows, pro 1, first of all, let the mobile phone be in standby state, and touch the back of the mobile phone without any operation. 2. If you feel hot or have a slight feeling of heat, the mobile phone may leak. 3. It can also be judged by looking at the power consumption of the mobile phone, in the case of excluding the power consumption of the software running in the background, if the electricity is faster than usual, it may be due to the motherboard leakage or battery damage 4

Remove the battery and the display, use the special stabilized power supply for mobile phone maintenance to turn on the positive and negative poles, and see if there is a current response without pressing the power button, if there is a leakage situation on the motherboard. 5. Mobile phone leakage is generally caused by water ingress into the mobile phone, which is more common. Hope mine is helpful to you, thank you and have a great day!

Is there any manifestation of motherboard leakage?

Teacher: Every time I hold my phone in my hand, it gets hot.

But if you put it on the table, it won't.

Hello dear, 1. The characteristics of the leakage of the motherboard of the Apple mobile phone are that the electricity is used very quickly, and the mobile phone continues to heat up seriously, and if it is not processed for a long time, it will also lead to a black screen, not turning on and other faults, which are caused by the burning of the motherboard chip, and the chip must be repaired. 2. Another symptom is: when the application is opened, the CPU heats up severely, and the battery buckle is hot.

In addition, severe heating during charging also indicates that the motherboard of the phone is leaking.

Hello dear, <>

The motherboard leaks, and the electric shock to the touch is strong, almost similar to the power leakage, and there is an obvious stinging sensation. Leakage from the motherboard can cause all components to become charged, including heatsinks, graphics cards, and more on the motherboard. Hope mine is helpful to you, thank you and have a great day!
