screen on time

[AlaaMMM]

Which device is better regarding battery (screen on time)

Galaxy  S 20 plus  or Not 10 plus ? 

And what is the period of screen on time for each mobile?

if you are addressing specs then the s20 battery is a bit larger capacity yet its not significant in general.

for your specific question a review addressing this issue should forwarded to a hardware tech, which I am not.

I would advice you to read the following article.
