Battery Weak Warning Even after changing battery

[AdityaB_07]

7-8 months ago i changed my Samsung S21 Plus's battery 

After for that time too

It was giving worst backup 

And the shocking part is this 

When i got this message 

Like what the hell is happening 

I gave 3.5k for new battery 

And even after that 

I was just getting on 3 hrs of SOT on very very normal usage 

And what should i do this worst phone 

[AdityaB_07]

As this should never be happened with even
From now i would never buy samsung phone or recommend one to buy
