Iphone 6s- Does not switch on, bypassing the charging system (how to do it?)

Hello

I have a problem with the Iphone 6s phone. The phone does not turn on. The screen remains black, the buttons' methods (Hard Reset type) do not help. After unscrewing and disconnecting the battery on the contacts after connecting the power supply (charger) there is voltage: 0.56V (and it should be 5V).
The charger has been replaced but no change.

I have a question
Do these symptoms mean damage to the power system?
Is it possible to omit this layout in this phone (to see if the disc is good), if so, how to do it? . I saw that it is possible in iphone 5, but the layout is probably different.

Please help

After connecting the phone (contacts behind the battery) under the service power supply set to 5V, the phone starts and operates. There is nothing under the loader

If the phone starts on the service power supply and on the battery, then maybe it would be good to start with a reliable, charged battery?
Second: the voltage on a fully charged battery should be 4.2V so why do you give it 5V on the power supply?

Okay, but the power supply is plugged in place of the battery and the phone works. But when I disconnect the power supply and connect the battery and power from the USB socket, nothing happens (and after disconnecting the battery the measurement in the battery socket is about 0.56V. I check with a charged battery and see what will happen.

I have topped up the battery with a service power supply. The phone still does not start

I have a simple question.

Is it possible to make a jumper or a connection on the motherboard that allows the phone to be switched on until the new power supply is purchased? How can you do this?

I am asking for advice

Too many guides from olive people

Replace damaged items as God has commanded and enjoy an efficient device.

Okay, so I have another question. The following layout is installed in this phone: 1610A2. Is it possible to use a charging system with the number: 1610A1 or A2?

This is not a charging system, you can use systems in revision 1610A1, A2, A3, A3B are interchangeable.
Personally, I recommend A3B due to the fact that they are presently produced and difficult to find for poor quality reefs. A1 are sold out of interest.

Hello

Today, it mentions the integrated circuit on A1. It worked hard but it worked out

I connected the phone to charging, and after a few moments I saw the illuminated display. When connected to a computer, the phone enters into emergency mode, but can not be restored. After about 10 minutes the display goes out and back again is the same (turns on, connects to PC and off).
Hard reset does not help.

I have a question. What could be the reason for this behavior?

I will add that the tapes are connected correctly

After carefully looking at the disc under the microscope, I saw that there are two components missing (resistors?) Next to the A1 (power supply) system. As I do not have a CD scheme, I ask on the forum: what are the elements and what can be replaced with them (eg jumper)? Can the phone fail to behave incorrectly due to shortages of these elements? In the attachment I am suggesting how the layout of these elements around the system looks like.

The scheme is available on google At home I do not have ZXW, I will not show you exact values. Do not call anything because you blow it up.
Replacing the battery, you can see it had a problem (bootloop?) Just from it (gets up on the power from the charger and turns off because there is no power (power) from the battery.
This can break the file system in NAND.

Hello

In the phone, after connecting the power supply, the screen rises as highlighted but nothing is displayed. It does not respond to the HOME button or you can not hear any sounds. Only the side button works. The battery has 3.7V. Could it be related to the battery?

The display is good because it worked before the fault
