Why my phone don't on

@akmaluddin22 you are not giving us a lot of information here. It would be nice if you would at least tell us if anything happened to your phone of it just died. It will also help if you tell us what you have checked and tried to fix this.

Start off by trying to reboot it so press and hold Volume Down (-) button and Power (or Lock) buttons together for 10 seconds and see if that makes a difference. If it does not, start by checking the basics

First check your charger. Make sure it has proper output. Then check your charging cable. Check to make sure connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. If none of this works, get a USB ammeter and see if your phone draws any amperage from the charger. If it does not it is possible that this is a charging port issue or a bad battery.

To check the charging port, use a voltmeter and measure the voltage on your battery connector. Next plug your phone charger in. Now measure the voltage on your battery connector. That voltage will have to have increased. IF not then the issue is either the port or the charging circuit.

You also need to check the flex cables coming from the charging board to the main board. Check that for micro tears and corrosion and proper connection to the boards. I suggest that you start with a new battery if any of the above did not work. After that it's the charging board and flex cables.

Since iFixit does not yet have a specific guide for this, use something like this video to work on your phone.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
