Why my phone don't started on

@rajendrara12756 you are not telling us what you have already checked and what you have already tried.

Start with the basic troubleshooting. 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. there is also a possibility that this is caused by a torn ribbon cable from the charging board to the main board. Check that cable for any micro tears or corrosion etc.

@rajendrara12756 aap hamen yah nahin bata rahe hain ki aapne kya-kya check kiya hai aur kya-kya koshish ki hai.

basik trabalshooting se shuru karen. sabse pehle apna charger check karen. pakka karen ki uska output sahi hai. phir apni charging cable check karen. dekhen ki connector mude hue to nahin han. uske bad, charging port check karen. usme fansi gandagi vagairah saaf karen; saaf karne ke liye hawa ka istemaal karen. agar isse bhi kaam na bane, to USB meter len aur dekhen ki kya aapka phone charger se koi amperage le raha hai. agar nahin, to ho sakta hai ki yah charging port ki samasya ho ya battery kharab ho.

charjing port check karne ke liye, voltmeter ka istemaal karen aur battery connector par voltage mapen. iske baad apne phone ka charger lagaen. ab battery connector par voltage mapen. voltage badhna chahiye. agar aisa nahin hota hai, to samasya port ya charging circuit mein hai. yah bhi ho sakta hai ki charging board se men board tak jaane wali ribbon cable fati hui ho. us cable mein koi chhota-mota cut ya jung vagairah to nahin hai, yah check karen.
