Replaced battery & charging port on 6p. Battery still drains at 1% per min.

[Neemayeswant]

My Nexus 6p is barely over a year old. Does not rapid charge and battery drains almost 1% every minute. Even when unused.Have ruled out all possible ROM issues. Have gone back & forth to all stock ROMs, cleared cache/reset everything. Still no go. Certain it is not the ROM.

Replacing the battery & the charging port has not resolved the issue. What else can I try replacing? Any suggestions?

Anything unusual in your battery stats? How's the cell signal throughout the day? Use GSam Battery Monitor to get a better idea of the cell signal, if you haven't already.

Hello B.Diddy, Thank you for your response.
I have Accu battery installed and besides the fact that it just shows how quickly the battery in draining, there is nothing unusual.
Cell Signal is perfect. Never had problems with it.
