Galaxy S21FE battery

[Members_mcwjMT8]

Hi,

It's been more than 18 months I'm using Samsung Galaxy S21FE and even after trying all the options available here and online, I'm getting poor battery performance. Hardly getting SOT of 5 hours and battery stand-by loss is 5-7 % per hour. So I'm thinking of replacing the battery of my phone. The question is, is it possible to replace the battery but, instead of regular 4500mAh can I put in 5000mAh battery in my Phone?

I know the battery dimentions are different in some cases and therefore asking here if there are any possibilities of getting a bigger battery with the same dimensions of the original battery of S21FE.

@Members_mcwjMT8 We do not recommend replacing the battery yourself, also, this phone is designed to have a 4500 mAh battery. 

What steps have you done to try resolve this?

I have taken all the steps that could be found in this forum but no improvement in the battery backup. It looks like global issues with the  battery backup of Samsung S21FE
