battery issue

[Dillon]

I recently purchased a Samsung S21 have to say the phone is very good in design but in battery life this is the worst device I have purchased I got more battery life in my Samsung s8plus 

So I hope Samsung will resolve this issues rather fooling people

Use power saving mode. Also use 60hz refresh rate instead of 120 as it take a toll on battery. Hope this helps

how to make it to 60hz

samsung s21 has one of the best battery optimization and capacity. It is adapting to your use .

yes I got the same answer from the authorised service here I'm kuwait, they told it will be ready within one month but God knows

the phone AI algorithm will take few weeks to understand your usage patterns and converse the battery as a result.

however, the battery ratings for S21 is far less than S21+ and S21 ultra.

[Ahmed6]

please keep in mind, the screen adaptive refresh rate in s21 and s21+ is varying from 48 HZ to 120 hz, and if you are scrolling on web or watching on YouTube it will stay at 120hz.
while the S21 ultra refresh rate is varying as low as 10 hz to 120 hz.. but the major difference is the screen type (LTPO) WHICH can reduce screen power consumption by 15 ~ 20%

What does that mean? Adaptive refresh rate Good or bad? Ultra better?

I am really worried about the battery. since I was using a Samsung s8 plus which had the same battery power gave me good life till three years
