Mwhy my mobile is not charging

@meronfiseha you are not giving us a lot to work with here. 6 words is just not enough to give you a detailed answer. WE can however, provide you with a couple of ideas.

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.

I suggest that you start with a new battery if any of the above did not work. After that you will have to check the charging port. In the case of your phone, it is soldered to the motherboard and thus requires soldering to repair it. To check it, 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 will have to give us the exact number for your phone since there are multiple variants out. It appears as if the No Charge flowchart is pretty similar between all models.
