battery issues

hi all
over the past 2 weeks my s6 edge plus battery has been behaving a bit weird
somedays i can get through the day with 50/60% left by the time i head home from work other days although 100% charged when i leave for work typically 7am by 10:30am it can be down to 50%!
i'm not doing anything different on the way to work which takes around 10mins i might look at a couple of emails whist listerning to spotify nothing heavy
i will charge to 100% before i go to bed and unplug it turn off...
