  • iPhone 6S voltage leak?

    Hi, I am new to iPhone motherboard repair and I have a bunch of iPhone 6S that have some weird issues. The issue is that when the phone is turned on and you go to setting the WiFi is grayed out and if you go to battery health it says service. However if you leave the phone on for a minute and then go back to settings the WiFi is not grayed out anymore nor does the battery health say service. Also another symptom of this is that when the phone is turned on the battery percentage will show a percentage that is below 10% and then it will jump to the correct percentage after a minute. With this being said the battery life drains quite fast as well. I know battery life can be caused by tristar and tigris but I was thinking the issue could be to do with one of the main power rails having voltage leak maybe? If anyone has had this issue before or knows a way to go about finding the problem that would be great. Thanks in advance.

    I have linked a YouTube video below of the issue to better show you what happens.

    A short within the wifi chip is common on iPhone 6s. Put a new battery in and see if it has rapid battery drain. Alternatively check the WiFi chip for heat with a thermal camera.

      Okay, I will try a new battery and also try a new wifi IC. I don't have a thermal camera.

        You will need a programmer to unbind the WiFi chip if you plan to replace it.
