[Closed] Best (not very) smart 'phone?

Ok. I realy don't like mobile 'phones but they seem to be a necessary evil nowadays. Up until a few months ago I had an old Nokia that was fine until I put it through the washing machine! One of my mates gave me his old Samsung Galaxy s4 and it's ok but it needs charging most days (I used to charge my Nokia every 2 to 3 weeks) and I don't use any of the doodahs on it apart from i'm in a Whatsapp group with my mates. Is there a 'phone on the market that is a very basic smart 'phone , Something that has a reasonable battery life and as few features as possible but is just about smart enough to run Whatsapp?
