This could be simply a case of my battery needs replacing. I noticed some odd behaviour the last few days such as I thought i had charge left then suddenly the battery is dead. So since its my day off I decided to intentially run the battery down to see for myself. So I've just been general browsing, a few texts, a little social media just letting it steadily decline. Then I watched it go from 26%, to 22%, to 10% to dead. In under a minute. Its an official samsung battery and other than that the phone is amazing with normally the best battery life of any phone i've had. IF its time for a new battery i'm happy to grab one on line now.
