The 5000mAh battery was the A21s selling point, so owners notice quickly when it fades. Batteries wear with charge cycles, and a 2020 phone that has charged every night has been through a lot of them.
An original Samsung battery brings back the capacity the phone was designed around. It is fitted by a trained technician at our authorised service centre, and part and fitting are included in the price shown.

Common questions
My A21s battery drains overnight doing nothing. Is that normal?
Not on a healthy cell. Standby drain that empties a 5000mAh battery overnight points to a worn battery, though a misbehaving app can do something similar. We check the phone before fitting anything, so you are not paying for a battery it does not need.
Why does the phone shut off when it still shows 30 percent?
A worn cell cannot hold its voltage under load, so the phone reads 30 percent and then dies the moment something demanding runs. It is one of the clearest signs of battery wear, and a new original battery normally puts the readings right again.
Is it worth replacing the battery on a 2020 phone?
If the rest of the phone still does what you need, yes. The A21s was built around that big battery, and a new original cell restores exactly what made it good in the first place. It is usually the simplest way to get more life from a working phone.
