Please use these tips from me: First tip, always keep dark mode on if thats fine with you, secondly, go to settings, then go to connections, go to more connection settings and turn off nearby device scanning because it uses a lot of battery in the background, and the third tip is to uninstall any apps that you don't use because the less apps there are, the less battery that will be wasted in the background. Before I changed all these settings on my s20 plus, the battery would last about 6.5 hours but now I have changed the settings, the battery gives me about 9 to 10 hours before it dies which is a huge improvement. Please use these tips and you will have a much longer lasting phone and battery. Hope this helps! Let me know if your battery lasts longer.
thanks I hadn't tried the scan nearby connection settings. its frustrating having to limit the functionality of your phone in order for it to last however. I'll see if it helps any it's Googlechrome that seems to be the main issue
