Interchanging battery with a higher capacity battery
Not Recommended in general


Battery Charging has various stages


 


These stages are regulated and controlled by the the charging circuit in charger/ in device by firmware files to switch to various stages. Battery capacity is very much integral to this. By replacing with a battery of higher capacity (or extended battery unless OEM approved) charging may less than optimal and therefore the performance or life of battery could be affected
Edit: The number of terminals and purpose could also vary ( some batteries have three terminals and some have 4). This would be an issue
Your case: There is hardly a difference in mAh so it may not matter at all , if it fits- normally OEMs like Samsung make sure that the batteries cannot be interchanged between devices - can't say about Redmi. The benefit you would get is marginal, so would recommend playing safe and not replacing to avoid any problems
