Samsung Battery Replacement in Florianópolis
Does your Galaxy not last until the end of the day, shut off at 30%, or get hot on the charger? Help Cell replaces the Samsung battery at Floripa Shopping, and you leave with your phone working.
- Ready in up to 2 hours on most models
- Technicians with over 10 years at the bench
- 90-day warranty on the service and the part
A Samsung battery replacement swaps the worn-out battery of your Galaxy for a new one, in the same phone. It is for people who charge the phone several times a day, for people whose phone suddenly shuts off, and for people who notice heat or a lifting back cover. At Help Cell, the service is ready in up to 2 hours on most models, at Floripa Shopping, with a 90-day warranty.
What a Samsung battery replacement is
A phone battery is a wear item: every full charge wears it a little, and after a few years it holds much less energy than when it was new. Replacing it fixes the problem at the root, without having to buy another Galaxy. Your photos, messages and apps stay on the same phone.
The repair is done at the workbench. The technician opens the phone, removes the old battery, fits the new one and closes everything before testing the charge.
Weak battery or a fault in another part
Not every battery complaint is the battery itself. An app stuck in the background, the screen at maximum brightness or a dirty charging port can also make the Galaxy drain faster or charge poorly. Help Cell checks which is which during the assessment, so you do not pay for a part that was not the problem.
Glued battery and phone sealing
On many Galaxy models, especially the newer ones, the battery is glued inside the body and the back cover is glass. Opening it takes care, so the glass does not crack and the battery is not damaged. The water resistance can be affected by any opening. That is why it is worth leaving the job with people who do it every day.
Original, genuine and compatible battery
An original battery is the part made by Samsung itself. A compatible battery is made by other factories, and its quality and lifespan vary a lot. Help Cell explains which part it uses for your model before it confirms the price.

How much a Samsung battery replacement costs
The price depends on the Galaxy model, the battery chosen and how hard the phone is to open. That is why Help Cell does not publish one fixed price. Send us the model and what is happening on WhatsApp, and the reply will come with the price for your case.
| Factor | How it affects the price | Example |
|---|---|---|
| Galaxy line | Each line uses a different battery, and the part affects the price. | A Galaxy from the A line and one from the S line do not use the same part. |
| Battery quality | Original and compatible batteries have different prices and lifespans. | The same replacement with an original battery and with a compatible one. |
| Difficulty of opening | A glass back and a glued battery take more time and care. | Galaxy with a glass back glued to the frame. |
| Battery condition | A swollen battery needs careful removal and may have damaged the back cover. | Galaxy with the back lifted by swelling. |
| Other faults along with the battery | A dirty port or a board fault adds to the job. | Galaxy that also does not recognize the charger. |
What nobody tells you before replacing the battery
Most disappointments with a new battery come from things that could have been checked first. These are the points that come up most at the workbench.
Weak battery or another cause: how to tell
Test the phone in safe mode
On many Galaxy models, restarting in safe mode turns off the apps you installed. If the battery lasts much longer in this mode, the culprit may be an app, not the battery. If it is still bad, the replacement makes sense.
Check whether the problem only happens with the charger
If the Galaxy only charges when you move the cable, the fault is in the port or the cable. In that case, Help Cell first does contact cleaning as a courtesy, which often solves the problem on its own.
Common mistakes with the Galaxy battery
Keep charging a swollen battery
A battery that swells can push the back cover and the screen, and the risk grows with heat. Unplug it, do not press on the phone and bring it in for an assessment. Read Swollen battery: what to do before it bursts.
Buying the cheapest battery without knowing where it comes from
A battery of unknown origin may have less capacity than the label says and may not last. Ask where the part comes from and what the warranty covers.
Waiting to replace it until the Galaxy shuts off in the street
People who wait until the phone dies completely often end up without a phone at the worst moment. Replacing it at the first sign lets you choose the day.
Checklist: before you bring your Samsung
Write down the model
In Settings, About phone, you can see the model name. With it, Help Cell can send you the price without you bringing the phone.
Back up if the phone still turns on
A battery replacement does not erase data, but a backup protects you against anything unexpected.
Have your charger and passcode handy
The store may need to turn on the Galaxy to test it. Confirm with Help Cell what it needs.

What customers say about battery replacement
Real reviews from people who replaced their phone battery at Help Cell, straight from Google.
They replaced my phone battery the same day even though it was an older model, and they also worked hard to find and apply a screen protector. Everything came out right, they do a great job with good service from the whole team.
Cristina RubyGoogle review, Jun 2026I love this store, and Matheus's service definitely makes all the difference. He deserves the best rating possible! I recommend the store with my eyes closed and I will happily buy here again. Score: 10000.
Efficient service on WhatsApp from Mykael and in the store from Josué. Excellent service! I took my phone in to replace the charging connector, but the technician checked it and, after a cleaning, found that the replacement was not necessary. The store did not charge for the cleaning either. Transparent, honest service and quality work. I recommend Help Cell!
