iPad mini 2 have charging problem

I have a iPad mini 2 here not charging.

It turns on everything but it does not charge.

Changed the battery, charging port, and charging ic.

All of the parts work cause I tested each part on another working device.

When I plug in the charger and turn on the device, it shows it's charging but it's fake charging. When I unplug it and plug it back in, it does not charge again.

I have noticed how the voltage drops when athe battery is connected to the device. When a cable is connected to the port, L5700 shows 5v.

With battery drops to 4v and when the device is turned on, its 3v, despite the charger plugged in.

Solution retenue

PPVBUS_USB (L5700) should not be dropping down to 3V when charging (or even 4V for that matter). To things could be going on here:

  1. The power source (charging brick or USB port) can't supply the necessary current and is being current limited , hence dropping the voltage.
  2. The power source is fine but the device is drawing excessive current due to a short or partial short somewhere.

If you have access to a USB Ammeter, you could use that to determine if the device is really drawing current when it says it's charging.

The tablet automatically turns itself on when the screen and the battery is connected to the motherboard. Could this be one of the problem?
