These numbers don't seem right to me. According to this Reddit used 8% of your battery after 5h of screen time. That means it would take over 62h of screen on time on Reddit for your battery to completely drain. This doesn't sound realistic. Even the S24 Ultra and Pixel Pro XL can only last ~12 - 14h under heavy use.
I can however confirm from my own usage of Summit, on a S24 Summit uses about 10% - 13% per hour of screen use. This lines up with the approximate 10h battery life of the S24 under heavy use.
Can you you let me know which phone you are using as well? Thank you.
