Question Pixel 6 battery stats are strange

Search This thread
When I was charging my phone with a power bank it was 28 Watts and the power bank i think is only 18 Watts and the charge time says 1 hour 40 and was done in maybe 40 minutes. And when I bought the Google charger 30w and cable or charged and said like 29 Watts and then 35 Watts I think. And the charging time said the same 1 hour 30 to 40. And only took probably like 40 minutes to. And now when using the phone the stats are the lowest I have seen for screen on Time using fkm battery recorder. Is this normal O feel like there's something wrong with the stats they should be different . phone last for ages though.
