Have you tried clearing the cache on the Samsung Members app? Also, did you replace your battery through Samsung or was it a 3'rd party phone shop?

Probably an old stock cheap Chinese battery that they obtained from eBay. Take it back and have them replace it again (if they even replaced it to start with).
