iPhone 6S Plus charging error: it won't charge after water damaged

The iPhone 6S Plus has been hit by water, but we had the first aid on it, then we test it, all is fine expect the charging issue. After iPhone dropping into water, it is slow to charge it and later it cannot be charged.

Solution

1. Use a tester battery to offer power to motheboard and test. USB current voltage meter shows that charging current jumps from 0.08~0mA. This phenomenon that there is no current when charging, but shows charging icon is called “battery drains”

2. Usually this issue is caused by the charging chip cannot output charging voltage. The frequent faulty points are USB chip damage or abnormal working condition of charging chip. Considering the inflow water in it, first we test the charging chip U2300. The charging management chip U2300 in bitmap is shown in picture 1.

3. The most frequently damaged parts in iPhone 6 and iPhone 6 Plus are voltage bootstrap capacitor C1402 and inductor L1401. The charging chip of iPhone 6S and iPhone 6S Plus is the same as iPhone 6. Based on the repairing experience of iPhone 6 and 6 Plus, we observe the surrounding circuits of U2300 under microscope and find that voltage bootstrap capacitor C2300 darken seriously. Therefore, we replace the capacitor and turn on to charge, its back to normally.


Tips:


In most of the cases, if iPhone 6S charging current is small or does not exist, we will replace USB Control IC and charging IC. If the problem is still the same, then we should check the charging voltage boost inductor and charging bootstrap capacitor.
