Battery Replacement for Galaxy A03 and A03s
The Galaxy A03 and A03s share a similar battery architecture, which means we cover the replacement procedure and the choice of components for both models in a single appointment. If you have noticed that your phone barely lasts half a day, shuts down at 20% or that the battery is swelling — it is time for a replacement.
What We Use and How We Work
For these models we use Original (Service Pack) batteries — factory Samsung components identical to those that come in a new device. Here is what you get:
- Factory capacity — a battery with the same mAh specifications as when you bought the phone
- 90-day warranty
- Replacement in 2 to 3 hours — no waiting for days, you pick up your device the same day
The procedure includes carefully opening the back cover, removing the old battery and installing the new Original component, with a check of all connectors and testing before the device is returned.
Our Recommendation
With 22 years of experience in replacing batteries in Samsung devices, we advise you not to wait until the battery fully degrades or physically swells — that can also damage other components. Visit us at Bulevar Arsenija Čarnojevića 91/3 in New Belgrade, and in 2 to 3 hours our team will install a new battery and give your Galaxy A03 or A03s reliable all-day battery life again.
