Samsung Galaxy S5

My Samsung Galaxy S5 is not older than 5 months old and cannot hold a charge. It has a very bad battery life and gets very hot for no reason. I will put in on charge overnight and in the morning it will only be at 40%, this morning it was at 14%. I feel that this is ridiculous and feel like I was sold a phone with a faulty battery or perhaps it's a bad batch.<br> <br> I have tried various cables and plug points and have cleaned the charge terminals and still my phone has terrible battery life. <br> <br> Kind Regards <br> Jeydine Otto
