With a 4500mAh cell, the S21 FE lasted comfortably through a day when new. Every charge cycle takes a little capacity with it though, and by now many FEs are hunting for a plug by early evening.
We restore that with an original Samsung battery, fitted by trained technicians at our Umhlanga workshop. What you see on this page is the full price for part and fitting.

Common questions
What kills the battery over time?
Charge cycles, mostly. Every full cycle wears the cell chemistry slightly, and heat speeds it up, which matters in a Durban summer. Leaving the phone on the charger overnight for years adds up too. None of it is misuse. It is simply how lithium batteries age.
Can I check the battery health myself?
Open the Samsung Members app and run the battery check under phone diagnostics. It gives you a life status for the cell. Pair that with your own experience of the phone. If it no longer lasts the day it used to, the diagnostic usually confirms what you already know.
Will the phone charge and perform like new afterwards?
The battery side of it, yes. An original 4500mAh Samsung cell restores the capacity and charging behaviour the phone shipped with. It will not make the processor faster, but a phone nursing a weak battery often feels off, and owners usually notice the difference after the swap.
