Redmi 12 Battery Replacement Singapore
Is your Redmi 12 no longer lasting through the day on its 5,000mAh battery? We replace worn or swollen Redmi 12 batteries with Grade A cells at our Singapore outlets, so your phone gets back its full-day battery life without you having to buy a new handset.
About the Redmi 12 Battery
The Redmi 12 was launched by Xiaomi in June 2023 with a 6.79-inch 90Hz LCD, a MediaTek Helio G88 chip and a 5,000mAh battery that charges at up to 18W through USB-C. Its large, bright 90Hz screen draws a lot of power, so after a couple of years of daily charging the battery’s capacity drops a lot.
A new battery brings back the original 5,000mAh capacity and stable 18W charging. The side-mounted fingerprint sensor, your data and your settings are not touched by the replacement.
Repair time: 30–45 minutes | Warranty: 90 days
Signs Your Redmi 12 Battery Needs Replacing
| Battery drains well before the end of the day, even with light use |
| Phone shuts down suddenly at 10–30% charge |
| Back cover lifting or a gap at the frame (swollen battery) |
| Charging takes much longer than before, or the percentage jumps around |
| Phone gets unusually warm while charging or during normal use |
| Phone only stays on while plugged into the charger |
If the Redmi 12’s back panel is lifting, the battery inside is probably swelling. Unplug it, don’t press the cover back down or try to open the phone yourself, and keep it out of hot places such as a car dashboard. Bring it to us as soon as you can.

Frequently Asked Questions
How long does a Redmi 12 battery replacement take?
Usually 30–45 minutes while you wait. It comes with a 90-day warranty.
Will I lose my photos or data?
No. A battery replacement doesn’t touch your storage, and your apps, photos and settings stay as they are. We still recommend a quick backup before any repair.
My Redmi 12 dies at 20% — is it the battery?
Most likely. When a worn battery can’t hold its voltage under load, the phone shuts down early even though the percentage still shows some charge. A new 5,000mAh battery fixes this.
Will fast charging still work after the replacement?
Yes. The Redmi 12 supports up to 18W wired charging over USB-C, and it will charge at that speed again with the new battery and a compatible charger.
Do I need an appointment?
No — walk in to any of our 4 outlets: Parkway Parade, Bugis Village, AMK Central or Jurong East (WestGate).
