php Editor Youzi iPhone6S motherboard leakage problem is a hot topic that many users are concerned about. Recently, some users reported that the mainboard leaked electricity when using iPhone 6S, which triggered widespread discussion and concern. Motherboard leakage will have an impact on the safety and performance of mobile phones, so sufficient attention must be paid. In this article, we will delve into the causes, solutions and preventive measures of the iPhone6S motherboard leakage problem to help everyone better solve this problem and ensure the normal use and safety of the phone.

The leakage of iPhone 6s is usually caused by the short circuit of BATT-VCC (battery voltage) or VCC-MAIN (main power supply). The other situation is that there is no leakage after powering on, and the leakage is about 100MA when it is turned on and in standby. Generally, the USB control IC is damaged, causing the 6S battery voltage to output the main power supply VCC-MAIN after passing through the charging IC. Mobile phone repair details: If there is power leakage or large power current, measure the resistance of BATT-VCC and VCC-MAIN to ground. If there is a short circuit, use rosin to whiten the parts of the motherboard, then apply voltage to the short circuit, and gradually increase the voltage from zero to find the short circuited parts.
It is recommended not to continue using it, because if the mainboard of the mobile phone leaks electricity, the mainboard will be burned in the long run, causing the battery to explode.
No matter what kind of mobile phone, leakage can be divided into two types based on the size of the current:
1. Small current leakage: the leakage current is less than tens of ma, and there are no obvious heating components.
2. Large current leakage: The current is close to or exceeds 100ma, and the leakage components heat up significantly, making it easier to find the cause of the fault.
1. Place the phone directly on the table, do not play with it, and observe it for a while. If the motherboard is leaking electricity, the phone will become very hot.
2. When the battery is fully charged, such as 80%, turn off wifi, Bluetooth and positioning functions, turn on airplane mode, lock the screen and record the time and battery at that time, leave it alone for more than 8 hours, and then check If the power consumption of the mobile phone does not exceed 2%, it is normal.
3. There is also a relatively simple method, which is to use an electric pen to measure. While the phone is charging, touch the body of the phone to measure.
4. Purchase a more professional mobile phone repair ammeter. This instrument can more professionally measure the circuit working condition of the mobile phone and determine the cause of the fault.
5. If it still cannot be checked out, it is recommended to go to the designated after-sales service for repair to completely eliminate the circuit fault of the mobile phone.
The specific repair price needs to be disassembled and inspected before quoting. iPhone 6 official new repair price list: Apple repair fees are divided into three major categories: screen replacement, battery replacement, and motherboard repair.
Screen repair fee, iPhone 6: $129, iPhone 6 Plus and iPhone 6S Plus: $149 Motherboard repair fee: iPhone 6s and iPhone 6 Plus: $329 iPhone 6 and iPhone 6 Plus: $319 Battery replacement : All iPhone models are $79.
