A 5000mAh battery was a big deal in 2020, and it is why so many A31s are still going. But charge cycles add up. After years of daily charging the cell holds less than it did, and you feel it by mid-afternoon.
We fit the original Samsung 5000mAh battery for the SM-A315F. Original cells are built to this phone's charging spec, and fitting by a trained technician is included in the price shown.
Signs you need this repair

Common questions
How long should the original A31 battery have lasted?
Batteries wear by charge cycles, not birthdays. Heavy users burn through cycles faster, so two identical A31s can age very differently. Once you are charging twice a day to get through it, the cell has done its work and a new original battery is the sensible fix.
Can I just use a power bank instead of replacing the battery?
You can carry a power bank, but it treats the symptom. A worn cell keeps degrading and can eventually swell or shut the phone off without warning. A new original Samsung battery restores the full 5000mAh and lets you leave the power bank at home.
Do you test the phone before replacing the battery?
Yes. Drain problems are sometimes software, a failing charging port or an app running wild in the background. We check the battery's actual condition first, and if the cell is not the problem we will say so rather than fit a part you do not need.
