I have the Samsung s3 mini. My battery swelled after about 15 months of use. I bought a new one and after 4 months I am now experiencing the same problem. I have never continued charging my phone once the battery has fully charged.Has anyone had a similar problem and if so how have you resolved the problem.
Thanks
