The charge on my devices don't last as long

I just moved and I have noticed that on both my samsing galaxy 3mini and my Kindle fire don't hold a charge as long. I'm charging my Kindle at least once a day when at my old apartment it could go probably 4 days with out a charge. With my galaxy the charge is lasting maybe 4 hours or less when it use to only have to be charged once a day. I feel like it had something to do with the outlets. I haven't done anything different with my devices and I moved in less than a week ago and they were both functioning fine then.
