Why is my phone not charging any more

@palmeramoah not sure what noise you hear but it could be a whining coil etc. Since you have not told us what you have already check, I would suggest that at first you 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.

Ultimately,I would start by replacing the battery as well as the charging port. I would do both since I then only have to open the phone one time and the parts are really not that expensive.

Since iFixit does not yet have a guide for your specific phone, Use this guide for the charging board and this one for the battery Those are written in Spanish. Use a browser that does the translating for you if needed.

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.
