[Q] Moto g 2014 battery sudden drop topic

I have a moto g 2014 bought from Amazon, it's rooted but running stock kitkat. I am using xposed framework. About a month after I got it, I noticed that when the battery got to around 15 percent, it would jump straight to 0 percent and died, then when I charged it back up, it would jump from 85 to 100. It has now been 3 months and the situation has worsened considerably. Today, the battery jumped from 87 percent all the way to 0.

See attached screenshots and any help would be more than welcome
