Typical Battery Problems on the Redmi Note 12 Pro+
- Your Redmi Note 12 Pro+ no longer survives a working day – it used to comfortably reach 6-8 hours of screen time
- The device suddenly shuts off at 20-30% remaining charge and only turns back on once plugged in
- The 5000 mAh battery gets noticeably hot during 120W fast charging
- The battery percentage jumps in big steps (60% → 30% → 10%) instead of dropping gradually
- The back panel bulges around the battery area – visible battery swelling after a deep discharge
- The Redmi Note 12 Pro+ won't start again after a full discharge, even after charging it for a while
- HyperOS shows a clearly reduced maximum capacity in the battery settings
How does the Redmi Note 12 Pro+ battery replacement work?
- Battery diagnosis via HyperOS + measuring device
HyperOS settings → Battery → Health shows the capacity. Our voltage/impedance measurement on the battery module confirms the finding. At under 80% capacity or a cycle count above 500 we recommend a replacement.
- Gently open the back panel
The Redmi Note 12 Pro+ is opened with a special suction cup and a warmed adhesive edge. The back panel is carefully lifted off without warping the plastic frame.
- Release the old battery
The battery cell is fixed to the plastic frame with pull tabs. We loosen the adhesive strips with isopropanol 99 – never using screwdrivers as a lever.
- Fit the certified 5000 mAh cell
A new li-polymer cell with identical capacity, 3.87 V nominal voltage and a precise form factor. Connector on the mainboard, adhesive on the frame, contact pressure controlled.
- Re-sealing + gasket
Old adhesive film removed, fresh Xiaomi adhesive applied, back panel re-bonded under pressure. 30 minutes of curing time.
- Full charge + calibration
First charge to 100% at 25 °C – HyperOS re-calibrates the battery gauge to the new cell. We check battery health and 120W fast charging.

What does the Redmi Note 12 Pro+ battery replacement cost?

How long does the new Redmi Note 12 Pro+ battery last?
With normal use the replacement battery lasts 500-700 full cycles at no less than 80% capacity – roughly 2.5 to 3.5 years of everyday use. One full cycle = a complete discharge from 100% to 0%. The warranty covers the cell and the fitting for 6 months.
Is the 5000 mAh battery for the Redmi Note 12 Pro+ a standard replacement or original?
We fit certified 5000 mAh battery cells to Xiaomi original specification: 3.87 V nominal voltage, the same capacity and the same charge curve. Genuine Xiaomi service packs are only available through authorised Xiaomi service centres. Our cells last measurably just as long.
Does 120W HyperCharge work on the Redmi Note 12 Pro+ after the replacement?
Yes. The 120W HyperCharge electronics sit on the mainboard of the Redmi Note 12 Pro+, not in the battery. Our replacement cell supports the full HyperCharge protocol and charges with original Xiaomi adapters in the same time as before. The cell chemistry is designed for high-current charging.
Does the Redmi Note 12 Pro+ have wireless charging?
No. By design the Redmi Note 12 Pro+ has no wireless charging – Xiaomi leaves out the Qi coil in this class to optimise price and weight. Charging works exclusively via USB-C at up to 120W.
My Redmi Note 12 Pro+ is bulging at the back – is that dangerous?
Yes, potentially. A swollen battery has built up gas pressure (the cell chemistry is at its end) – a fire/explosion risk, especially in heat. Bring it to us immediately: hazardous-goods disposal handled directly by Reparo, replacement for EUR 55. Don't charge the device any further until then.
Does the display get damaged during the Redmi Note 12 Pro+ battery replacement?
No, not with us. We open the Redmi Note 12 Pro+ from the back, so the display stays untouched. On aluminium/plastic models we pay particular attention to heat management so the plastic frame doesn't warp.
Can I just drop my Redmi Note 12 Pro+ off at Reparo?
Reparo has no on-site customer access. You book an appointment online – our courier comes to your address across all 23 Vienna districts. From the provinces, insured shipping with return included in the price.
How does the pickup service in Vienna work for the Redmi Note 12 Pro+ battery replacement?
Book online, choose a time slot between 9am and 6pm, and the courier drives to your Vienna address (1st district through to the 23rd, Liesing). The battery replacement takes 60-90 minutes at the studio, with return often the same day. Pickup service starts from EUR 7.90 by district.
Is shipping from the provinces safe for a Redmi Note 12 Pro+ battery?
Yes. Battery shipping falls under hazardous-goods class 9 – we send a UN-approved shipping box. The Redmi Note 12 Pro+ arrives insured in Vienna and goes back the same way after the replacement, with free return shipping. We regularly serve customers from Graz, Linz, St. Pölten, Klagenfurt, Innsbruck and Bregenz.
Will I lose data during the Redmi Note 12 Pro+ battery replacement?
No. The flash storage, Mi account and SIM card are not disconnected during the battery replacement. Photos, WhatsApp chats, apps and settings all remain fully intact. A Mi Cloud backup before any repair is still recommended.
How long is the warranty on the new Redmi Note 12 Pro+ battery?
Six months on the battery cell and the fitting. If the cell loses more than 10% of its capacity in that time: a free re-replacement. Deep discharge from leaving the phone unused for months is not covered.
Do I lose my Xiaomi warranty through the Redmi Note 12 Pro+ battery replacement?
The original Xiaomi warranty (1 year) on the Redmi Note 12 Pro+ has been expired for 2 years. The Reparo warranty runs 6 months from fitting.
Is the Redmi Note 12 Pro+ battery replacement still worth it in 2026?
Yes. A battery replacement at EUR 55 vs. a used device with a fresh battery from around 79 € – plus migrating your data, setting up a new Xiaomi account and lost apps. The Redmi Note 12 Pro+ still receives HyperOS updates from Xiaomi.
