Hey i saw on the Samsung site that it says "up to 27 hours video play back time". How long should the phone last on 100%charge? I know its different for everyone but if this roughly right. I have dark mode on, battery adaptor and all the powee saving options on. Thank you in advance.
The problem you have is social media apps which suck the life out of your battery. In the first screenshot 52% of your battery has been used by these apps.
Under these circumstances and usage your battery is doing well.
