iammrkt , via OnePlus 6 , May 31, 2020 : Battery back up has been gradually worsening faster than expected on Oneplus 6 device. Has to be charged 2 to 3 times a day with moderate usage. While we all understand that a 2 year old device wouldn't give battery back up as a new one, the performance should not be that poor either. All apps are using battery normally as per the stats. Phone has been factory reset with no app backup. Still no difference. Any fix will be appreciated.
