I have a weird bug in the battery graph

https://ibb.co/5G59RcP
(didn't shut down the phone) is this an android stock problem?

koryey I see gaps in my battery graphs sometimes too. Not sure what causes the gaps. Most likely an upstream bug.

Sorry if this is a dumb suggestion, but is it possible the phone was connected to a power supply during those times?

Had the same issue from time to time in my stock 7pro
