why my phone takes 14 hours to get charged?

[AC Question]

I have brought new samsung j5 almost a month ago. My phone used to take 2-3hours to get charged completely but now it takes approximately 14 hours to get charged. My phone's battery timing is same so it is sure that my phones battery is okay and I have two original chargers, still facing same issue.

Same charging routine? (You still charge with the phone running, or with the phone turned off?) Then it sounds like a bad battery. If you completley discharge the battery before every charge, it's amazing that it's lasted a month.
