I have been trying everything I can to boost my s21 ultra's battery life. But nothing helps.
Later I found using 2 third party apps that my battery capacity is only 4558 mAh instead of the designed 5000 mAh. Which is 10% less.
It's not even a month since I bought this phone!
Should I visit the service center? Or is there some way to fix it? Attaching some screenshots of battery life and capacity.
In one screenshot you can see the screen on time was 4 hours 46 minutes and total battery life was 12.5 hours. In which the battery went from 100% to 1%
Something weird, because chrome only ran for 10 or, 11 mins, but consumed almost 30 percent of the battery 🤔. Something wrong with chrome. Maybe reflashing software from service center may resolve this issue. Btw, your battery is in good condition, no need to change.
