Galaxy a50s battery

[Akkiji19]

My galaxy a50s battery drains so fast almost in 3 hours of use, I know it's a common problem as it becomes 4 years in 2023, then I thought to replace it's battery. 

Is it a good idea to replace the battery because there is a fear in my mind that Is this replacement cause any other problems in phone. 

And the another doubt that if it's good to replace battery then can we replace it's 4000 mah battery with 5000 mah?
