I had Redmi Note 8 Pro in my family. After 3 years, the battery started to swell. I had to get it changed. Its then when I also started using Accu battery. Check if your phone's battery isn't swollen, and even if it isn't you can get your battery replaced. It might be EOL.

No matter how much you try to perfect your charging cycle, battery power tends to degrade overtime. 78% Health is honestly a good number after 3 years of usage so you have nothing to worry about.
