This and also battery wear is why I charge my phone exclusively with wireless charging with all the fast charging toggles turned off.

I have nothing constructive to contribute other than I feel smug and superior because I have a fairphone, so I can change mine if that ever happens.

Mine is at the point where there is only one specific USB-C cable that I can charge it on.

Literally all other cables simply won't charge it, and now it's at the point where I need to have that cable in a very specific position for it to charge.

At least wireless charging still works, the phone is only 3 years old, I really should replace the battery and port

People have offered great advice, one special case: Does your phone still have microUSB for some reason? In that case you might just need a new cable

Get a wooden toothpick and snap it in two (unevenly is better). Then use a pointy bit to clear out all the dirt, dust and grime from your phones port. I had the same problem a few weeks ago with my phone, after a good 20 minutes of careful scraping my phone is fine now. Best of luck.

So, the first thing you need to do is to figure out if the problem is in your phone or in the charger. Try either charging your phone with another charger or using your charger to charge someone else's phone.

If the charger is the problem, it's most likely broken inside and you need to get a new one. Tape might do the trick for a short time.

If the phone is the problem, try cleaning out the charging port. I personally use bamboo cocktail sticks that I crush with pliers to make them have small rough bristles. Lots of objects work for this (pretty much anything thin, preferably brush-like), just as long as you don't put anything wet there.

I have the same with the headphone jack of my laptop...

I tried to clean it but that didn't help.

All these legitimately helpful fucking comments and no one’s pointing out that you can easily fix the problem by placing the smartphone in microwave and nuke it for a minute on high* to get your phone up to 80% charge.

*^Charging times dependent on microwave power output and your zodiac sign. Lower wattages may result in tastier special brownies. If unsure, please consult your primary care phrenologist.^

Great time to try wireless charging if you have a device that supports it.

I got some magnetic detachable usb cables and the end that detaches never gets unplugged from my phone. Although i mostly charge mine with a wireless pad on my nightstand.

1. Test the cable first if you have a spare.
2. Test the AC adapter if you have a spare.
3. If both fail, inspect the charging port with a flashlight. 4a) If it looks dirty, try cleaning it out with a toothpick (if you have a dedicated plastic tool for mobile repair, use that). 4b) If it doesn't look dirty, refer to 4a. What often happens is that lint from your pocket compacts over time as it gets in there and then gets pressed in by the charger.
4. If this doesn't work and you have a good, locally owned mobile repair shop nearby, they might look at the port for free just to see if there's anything you missed.

Only after all of this would I start to strongly consider the phone itself as the culprit.

I had a little plastic army guy go missing from my diorama. Turns out, he was in the charging port,of my phone. :)

One time my headphone stopped working without weird angle thing.
Out of nowhere. Just stopped working.

It was perfect with good quality sound befire but no "only one ear" or "certain angle" or "bad quality sound" nope.

I didn't have my guard up and paid dearly for it.

It's usually just dirty

Mine started doing it too. Turns out the charging port was full of dust!

Time to clean the lint out of the charging port
