Why iPhone 6S Plus will not charge after water damage

If you iphone 6S Plus will not charging when water damage ,You can set up a return online at vipprogrammer.com or call your local Apple Store to make an appointment with the vipprogrammer of repair guide. If you decide to go to the Apple Store, it’s always a good idea to have an appointment at the vipprogrammer before you go in so you don’t have to wait in line.

After iPhone dropping into water, it is slow to charge it and later it cannot be charged.

How to repair?

Step as follows:

Use a tester battery to offer power to motherboard 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”

The charging chip cannot output charging voltage normally, which causes the above problem. 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 5-54.

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. Trouble is removed.

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.
