- Ready in up to 2 hours, while you wait in the store
- Our own technicians, no outsourcing
- 90-day warranty on the service and the part
A Xiaomi battery replacement is the service where the worn-out battery in your Xiaomi, Redmi or Poco is swapped for a new battery of the same model. It is for people who run out of charge before the end of the day, see the phone shut off on its own, or notice the battery getting hot. At Help Cell the service is ready in up to 2 hours, at Floripa Shopping, with a 90-day warranty.
What is a Xiaomi battery replacement
A phone battery wears out. Each charge and discharge uses up a little of it, until it holds much less energy than it did on the first day. The replacement gives the phone a new power source. The phone itself, with its photos, contacts and apps, stays the same.
On Xiaomi, Redmi and Poco phones, the battery is almost always glued or held inside the body, with no cover that the owner can open. That is why the service requires opening the device carefully, and this is where a skilled bench makes a difference.
Xiaomi, Redmi and Poco: are they the same thing?
They are product lines from the same manufacturer, Xiaomi. Redmi covers the entry-level and mid-range models, Poco focuses on performance at a lower price, and the line called just Xiaomi has the top-of-the-range phones. The battery changes from one model to another, so the exact name of your phone matters to find the right part.
Original, genuine or compatible battery
An original battery comes from the manufacturer itself. Genuine is a market term for parts with factory-level quality, with no fixed standard, so it is worth asking where the part comes from. A compatible battery is made by a third party and varies a lot in lifespan and safety. Help Cell tells you which part it uses for your model before it confirms the price.
When a battery replacement is not the answer
Not every phone that drains fast needs a new battery. Apps running in the background, the screen at full brightness and a weak signal also use up charge. If the problem is the charging port, Help Cell shows that during the assessment, before you pay for a part that would not solve it.

How much a Xiaomi battery replacement costs
The price of the replacement depends on the model, the battery chosen and the condition of the phone. That is why Help Cell does not publish a single price: send us the model on WhatsApp and the reply comes with the price for your case.
| Factor | How it affects the price | Example |
|---|---|---|
| Phone model | Each model uses a different battery, with its own price. | The battery of an entry-level Redmi and the battery of a top-of-the-range Xiaomi. |
| Part quality | Original, genuine and compatible batteries have different prices and lifespans. | The same replacement with a factory part and with a third-party part. |
| Difficulty to open | A phone with a glass back and strong glue needs more care and time. | A model with the back glued on and the battery held by adhesive. |
| Swollen battery | A swollen battery may have pushed against and damaged other parts. | A screen lifting because of the swelling. |
| Faults along with the battery | A faulty charging port or board increases the job. | A phone that does not charge even with a new battery. |
What nobody tells you before replacing the battery
Replacing a battery seems simple, and that is why many people decide wrong. These are the points that matter most in practice.
Common mistakes when replacing a Xiaomi battery
Buying the cheapest battery online
A part of unknown origin may last only a few months, get hot and, in the worst case, swell. What you save on the price, you lose in lifespan and safety.
Continuing to use a swollen battery
If the back cover lifts or the screen comes loose, stop charging. A swollen battery is a risk of excessive heat. Read Swollen battery: what to do before it bursts and bring the phone in.
Replacing the battery without checking the charging port
If the phone does not charge because of dirt or wear on the port, a new battery will not fix it. The assessment tells the two cases apart.
Checklist: before you bring the phone in
Make a backup if the phone still turns on
A battery replacement does not erase data, but a copy of your photos and contacts protects you against anything unexpected.
Write down the exact model name
In Settings, About phone, the model name appears. With it, Help Cell can give you the price without the phone in your hand.
Bring the charger and your lock code
The store may need to turn on and test the phone. Confirm with Help Cell what it needs.

What customers say after replacing the battery
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!

Frequently asked questions about Xiaomi battery replacement
How much does a Xiaomi battery replacement cost?
The price depends on the model and the battery used. Send us the model on WhatsApp +55 48 99110-7381 and Help Cell replies with the price for your case.
How long does the replacement take?
Up to 2 hours, while you wait at the Floripa Shopping store. If the phone has another fault as well, such as the charging port or the board, the time may change and the store will tell you before continuing.
Will I lose the data on my phone?
No. With a battery replacement, photos, contacts and apps stay on the phone. Even so, make a copy before if the phone still turns on. Help Cell also does data backup.
Is the battery you use original?
Ask about your model on WhatsApp. Help Cell explains which part it uses and what differs between original, genuine and compatible, so you can decide with the price in hand.
Does the battery replacement come with a warranty?
Yes. The 90-day warranty covers the service and the part against defects. It does not cover drops, liquid or misuse after the replacement.
My battery is swollen. Can I still use the phone?
It is not recommended. A swollen battery can overheat and damage the screen. Stop charging, do not press or puncture the battery, and bring the phone in. See what to do before it bursts.
Can I make the battery last longer before replacing it?
Some habits help, such as lowering the brightness and closing heavy apps. But a worn battery has a limit, and no setting gives back the lost capacity. Read How to make your phone battery last longer.
