Overview
What this Xiaomi Redmi Note 9 / Redmi 9 battery is
Fixing a Xiaomi Redmi Note 9 / Redmi 9 with a new battery costs £12.29, a fraction of the price of a replacement handset. It is the part behind searches like "order xiaomi redmi note 9 battery" and "xiaomi redmi note 9 battery online": brand new and OEM standard. You may also have searched "xiaomi redmi note 9 battery for sale". Batteries age with every charge cycle, so a new one is often the fix for short run times. Supreme Phone Parts Ltd tests every unit before dispatch and sends it from Manchester with a VAT invoice. Delivery in the UK is £3.49 with Evri.
Fitting this Xiaomi Redmi Note 9 / Redmi 9 battery addresses a Xiaomi Redmi Note 9 / Redmi 9 that drains quickly, drops from a healthy percentage to a sudden shutdown, or needs charging several times a day. It also helps when the phone will not hold a charge overnight or the percentage readout jumps around.
The Xiaomi Redmi Note 9 / Redmi 9 battery price here is £12.29, plus £3.49 UK delivery, for a new part made to OEM standard.
The pack contains the battery only. Adhesive and repair tools are not included.

Before you order
Is this the right battery?
Signs it needs replacing
- The percentage jumps, for example from 30% straight to 5%
- You need to charge it two or three times a day
- The back cover or screen is lifting from the frame
- It will not stay on unless it is plugged in
Check before ordering
- Confirm your device is the Xiaomi Redmi Note 9 / Redmi 9. Check Settings › About phone, or the model label, before ordering
- Make sure it is not a similarly named model, as other variants can use different parts
- Try another charger and cable first, to rule out a charging fault
- Line up a repair shop or technician before the part arrives
Professional installation
How a technician fits this battery
- Power the device off. Warm the edges of the back to soften the adhesive and lift it free, or open it as the model requires.
- Remove any internal cover plates, then disconnect the battery connector before touching anything else.
- Lift the old battery out using its pull tabs or low-tack adhesive. Do not pry with metal tools or puncture the cell.
- Clean the frame and fit the new battery. Connect it and power on to test charging and runtime before sealing.
- Reseal with fresh adhesive and press evenly into place. Check charging, signal and the camera.
Take your time opening the Xiaomi Redmi Note 9 / Redmi 9, because the battery sits close to other components. Power down, unplug the battery connector first, then remove the worn cell and fit the new one. We recommend a trained technician if you have not opened this phone before. Check that the part matches your device before fitting it or removing any adhesive backing. Parts with adhesive or glue applied can’t be returned for a change of mind. Faulty parts are always covered.

Item arrived promptly which is always the case with this seller. And as usual well packaged. Sadly the postal service mishandled it and may have caused the failur eof the unit. Seller made instant refund. Decent communications too when i am sure they have a ton of orders to juggle. I have no issue recommending them and have now had half a dozen digitisers and all te others worked so far.
