Once it was 23 hours with me. It was because i accidentally dropped my phone in the sand and the charge port was blocked. I cleaned it and it was normal. Use a cotton earbud and wet it with water and clean charge port. Leave it to dry and then it will be fine. If dirt is more you can use a pair of tweezers. Or you can buy a charge port cleaning tool which will have what you need. If charge port is clean it could mean 3 things.
1. Wire is not secured properly
2. Charger speed is slow
3. Damaged charge port (replace charge port neccecary)
