The Galaxy A54 is an outstanding Samsung device that combines advanced technology with affordability. Its battery is the key component powering the vivid 6.4-inch Super AMOLED display, the Exynos 1380 processor and the advanced camera system. With regular use, the battery gradually loses capacity, which shows up as shorter runtime and the need to charge the phone more often. At Viper Mobile, for the Galaxy A54 we use exclusively genuine Samsung batteries from the Service Pack program, priced at 7.000 RSD for the complete service. This price covers the original component, professional installation and our warranty, making it an optimal investment for restoring your phone's functionality. Service Pack batteries go through the same quality control system as factory components. That guarantees that after the replacement your Galaxy A54 will have fully restored capacity and full compatibility with all the advanced power management features that Samsung's One UI system provides. Adaptive battery optimization, which learns your usage habits, will work exactly as it does on a new phone. The construction of the Galaxy A54 requires a specific approach because of the placement of sensitive components such as the camera modules, the NFC antenna and the wireless charging system. Our technicians use specialized tools for controlled heating and precise opening, with no risk of damaging the internal components. Removing the old battery is done gradually, since the component is secured with high-quality adhesive strips. The new battery is positioned exactly like the original, with particular attention to the connector, which must be perfectly aligned with the connector on the Galaxy A54. Our shop is located at Bulevar Arsenija Čarnojevića 91/3 in New Belgrade, strategically positioned for easy access from all parts of the city. For the Galaxy A54, the battery replacement takes about an hour, during which you can stay in our shop or take care of other things nearby. We recommend booking an appointment by phone at 065/362-61-31 to avoid any waiting. During the process, all your data, apps and personalized settings remain untouched, as the system is not reset. With a newly installed genuine battery, the Galaxy A54 regains its original endurance, allowing a full day of use without extra charging. Our 90-day warranty protects your investment and gives you peace of mind while using the phone. Many years of experience since 2004 in servicing Samsung phones allow us to recognize and resolve all the specifics of the Galaxy A54 model. Our customers often tell us how satisfied they are, because after our work the phone performs like a completely new device.

Frequently Asked Questions About Battery Replacement
How do I know if I need a new Samsung battery?
Open Samsung Members → Support → Phone diagnostics → Battery status. Samsung does not show a capacity percentage the way iPhone does — it gives a rating: Normal, Weak or Bad. On newer models (S23 and up) the exact percentage and charge cycle count also appear under Settings → Battery and device care → Battery. Practical signs it is time for a replacement: the phone shuts down at 20-30%, the battery drains faster than before, charging takes longer than usual, or the battery is physically swollen.
How long does Samsung battery replacement take?
From 2 to 3 hours. The battery swap itself is the shorter part of the job — most of that time goes to curing the adhesive that holds the back cover in place. That step cannot be rushed: if the phone is collected before the adhesive sets, the cover will not seat properly. That is why the device stays with us for the full period.
Will I lose my data during Samsung battery replacement?
No. Battery replacement does not affect your data, photos, apps, or settings on your Samsung phone. We never erase anything and never ask for your unlock code. One thing to know before the repair: after a battery replacement the phone is no longer water resistant, because the factory seal is opened once and cannot be restored to factory condition.
Is the Samsung battery original?
Yes. We use exclusively original Samsung batteries from the authorized distributor with full factory capacity. No copies or generic replacements — only originals compatible with Samsung fast charging technology.
Will the phone perform like new after a battery replacement?
The battery will be new — but the phone will not behave like it did on day one, and that is not down to the battery. Apps have grown several times over: what used to take 30 MB now takes 150 MB and draws far more power. So a new original battery in a Galaxy S21 after five years of use will not last as long as the factory one did — the same capacity now powers a much heavier load. A battery replacement fixes sudden drain, shutdowns at 20-30% and charging several times a day; it does not turn the phone back into the year it was bought. An original Samsung battery typically retains over 80% capacity through the first 2 years of normal use (about 500 charge cycles).
How much does a Samsung battery replacement cost?
The price depends on the model — exact prices for every Galaxy model are listed in the price table on this page. The price is fixed per model and includes an original Service Pack battery, professional installation and VAT, with no hidden costs. If your model is not in the table, call us for an exact price.
What warranty do I get on a Samsung battery replacement?
The warranty is 3 months (90 days) on the installed battery and labor. The exception are Galaxy Z Flip and Z Fold models — repairs on foldable devices are performed only with the customer’s consent and without warranty, because authorized suppliers do not provide a warranty on parts for those models. The battery warranty also does not apply if the back cover is cracked — a shard of glass can fall inside and puncture the new battery. If we replace the back cover during the same visit, the battery keeps its full warranty.
