S3 charge jumps

[Kamakazzi]

Every now and again, I'll unplug my phone in the morning and it'll say the battery is at 100% but after a few seconds, it'll drop down to a lower percent. I'm using an app that shows what the battery is doing while its charging. I've attached a screen shot. Anyone know why its doing this? Thanks

It's a bad battery - purchase a replacement and give it a good charge.

I just bought it about a month ago and the battery before this one did the same thing...
