I have had a similar problem with my iPhone 6. What worked for me was re-calibrating the battery. Now this may not work for you as there can of course be multiple problems, but is worth a shot.

# Firstly charge up your phone fully, and once at 100% leave charging for an hour or so more.
# Now unplug and use your phone like normal.
# Take it all the way down to 0% and allow it to die.
# Ideally you want to leave it overnight or for 4+ hours with the battery dead. If you cannot do this allow it to be dead for as long as you can.
# Now recharge the phone fully and it should have recalibrate the phones battery.

I hope that this helps.
