Battery dying after only 9 months

[Fennijer]

Hi guys, 

The last three days my phone battery is lasting 7 hours max if I don't use it and with stamina mode on.

If I use it, even to text, it lasts less than 2 hours. 

I've had this phone 9 months, what on earth is happening?

Any suggestions what causing this or how to fix it?

Thanks
