Samsung A30s battery issue

[Vinceanamazing]

When my battery reaches 15 percent it will suddenly drop to 1 percent and shutdown any idea how to fix it and I bought my A30s last may 2020

Great Samsung afternoon! I'm Sam, your friendly Samsung Customer Service guy. Have you tried to check your battery in Samsung Members by doing interactive checks? If not, you may try it first then it will show you the result if you need to go to the Service center. Stay safe and have a nice day ahead!
