Battery Fluctuation

Jun 9, 2016
I am on the latest xiaomi eu rom 6.10.20
And since the last update 6.10.13, I've been experiencing battery fluctuation.
All of the sudden the battery gauge shows 1% and battery low notification. Then after sometime it will start showing the original value and then will show something lesser.

What can be done?
I have already cleared cache, dalvik and data. Didn't help!
Anything else?
