When I go into settings > battery. One minute it tells me at 75% I have over 30 hours remaining and then at 70 I have over 16 hours. I dunno how it can go down dramatically.
Is this normal??

Over time it should balance out as it develops a battery optimisation based on your historical use.
Importantly you should easily be getting a full days use without a charge and fast charging will get you to around 70% battery in around 30mins or so.
