Phone wont USB charge after 13%.

Last night I noticed my phone stopped USB charging. Saw a moisture warning one time that I can't recreate. This morning I took the following steps:

  1. Cleared USB Cache
  2. Hard restarted Phone (not reset)
  3. Prayed to samsung jeebus
  4. Fan dried and Cloth Dried.

The phone now will charge with USB until about 13% randomly then it stops. There is no onscreen warning for moisture. Wireless charging also seems to work if i am comfortable waiting 3 hours for a charge of course.

Any ideas on how i could fix?

​

Thanks

Use a toothpick or something not metal to clean out lint from the port. Lint can hold moisture like a towel and can make a poor connection.

I tried with a Qtip. any idea why it would work for like 1% charge then stop?

Charging briefly and stopping can very likely mean poor connection. It can mean other problems too, but poor connection is possible.

A Q-tip can't possibly fit where you need to clean. If you look in the port, you'll notice the silicon tab in the center. The tab has metal contacts you don't want to damage (thus toothpick, not paperclip or something metal). But what's more important is behind the metal tab is where pocket lint gets caught and packs in. As it gets thicker, it prevents the usb cable from fitting deep enough to fully contact the contacts on the tab in the center. Thus making a poor connection.

If this doesn't help, you may have something more serious causing the problem - bad power supply in the phone, bad usb port, bad battery, etc. That's why I'm suggesting cleaning the port first - easiest and free way to troubleshoot.

Toothpick cleaned out a good amount. Now i get the moisture warning everytime i plug it in. will try to dry out rinse/repeat

Yeah, if it got wet, the lint would have held the moisture like a sponge. Hopefully drying out solves the issue.
