Cracked screen, a charging port that’s clogged with grease and dust, or a battery that’s not living up to its big mAh number? Case Indulgence Underwood repairs the full Xiaomi and Redmi range — Note, Redmi standard, POCO and Mi flagship models — with a free diagnostic before you commit to a repair.
Xiaomi and Redmi phone repair is the diagnosis and fixing of hardware faults on Xiaomi, Redmi and POCO devices — cracked screens, worn batteries, damaged charging ports and camera issues — usually completed the same day using certified parts. Case Indulgence Underwood is a walk-in Xiaomi/Redmi repair specialist at Underwood Marketplace on Logan Rd, serving Underwood, Springwood, Rochedale, Kingston, Daisy Hill and Priestdale.
The Kingston Rd and Logan Rd dealership strip shapes several of our Underwood pages, but the Xiaomi/Redmi pattern here comes from a specific corner of it we haven’t covered elsewhere: workshop and service department staff. Mechanics and service advisors work around grease, metal dust, tools and vehicle hoists all day — a genuinely different environment to the sales floor or the finance office — and a meaningful number deliberately choose a budget Redmi or Xiaomi specifically because they don’t want to risk an expensive flagship getting greasy, dropped from hoist height, or clogged with metal dust.
Redmi’s marketing around huge battery capacity is also a genuinely practical selling point for this group rather than just a spec-sheet number — workshop staff often can’t step away from a job partway through to charge a phone, so a phone that lasts a full shift on one charge matters more here than it might for someone in an air-conditioned office.
Xiaomi phones also have their own quirks that generic repair pages skip past. MIUI and HyperOS tie a phone tightly to a Mi Account in a way that can genuinely lock a device if it’s mishandled during a factory reset, and grease and metal dust from a workshop environment get into a USB-C port more aggressively than office or car-yard dust. Both are covered honestly below, before you book anything.
Flat-edge glass cracks corner-first on most Redmi and Xiaomi models — small chips spread quickly if left unrepaired.
Metal dust and grease from a workshop environment can pack into a USB-C port more aggressively than everyday pocket lint — a genuinely different fault pattern to a phone used mostly indoors.
Large-capacity Redmi batteries still degrade with age like any battery — check Settings > Battery for real usage before assuming it’s a fault.
Can be grease build-up inside the port rather than a failed charging chip — this is the #1 “try this first” check below for anyone working around tools daily.
Some warmth during fast charging on a large-capacity Redmi battery is normal — persistent heat or swelling is not.
In-display and side-mounted fingerprint sensors on Xiaomi/Redmi models need proper recalibration after any screen swap.
Common after a drop even without visible screen damage — the lens or sensor shifts inside its housing.
Can follow a factory reset or software issue if Find Device wasn’t disabled first — see below for what this means honestly.
Of the Xiaomi and Redmi phones that come through our Logan Rd store, charging ports affected by grease and metal dust from workshop environments are more common here than the general grey-import pattern we see at other stores. If that sounds familiar, book a free diagnostic and we’ll confirm exactly what’s going on before quoting anything.
Ordinary pocket lint is fibrous and loose, and usually clears with a gentle clean. Metal dust and grease from a vehicle workshop behave differently — fine metal particles mixed with a small amount of grease residue on the hands pack together inside a charging port rather than sitting loosely, and that combination is genuinely harder to clear and more likely to interfere with a firm cable connection. A phone used all day in a workshop environment builds up this kind of port contamination faster than one used mostly in an office or outdoors.
Xiaomi phones running MIUI or HyperOS can be linked to a Mi Account with Find Device enabled, similar in concept to Find My iPhone or Samsung’s Reactivation Lock. If a phone is factory reset — during a repair, after a software fault, or even accidentally — while still signed into that account with Find Device active, the phone can become locked and effectively unusable without the original account username and password. This isn’t something a repairer, including us, can bypass or remove. We always check Mi Account status before any repair step that risks triggering a reset, and we’ll tell you honestly if your phone is at risk before we touch it.
Redmi’s headline 5000–6000mAh+ batteries are genuinely larger than most competing phones at the same price, which matters practically for anyone who can’t step away from a job to charge mid-shift. But battery chemistry doesn’t care about size: a bigger lithium cell still loses roughly the same percentage of capacity per full charge cycle as a smaller one, typically dropping below 80% health somewhere around 500 cycles, or about 2 years of daily use.
Not every fault needs a paid repair. These checks take a few minutes and cost nothing:
If none of these fix it, the issue is almost certainly hardware — book a free diagnostic and we’ll confirm exactly what’s wrong.
Fill out our short online form with your model and what’s wrong — takes under a minute, no account needed.
Bring your phone to Case Indulgence Underwood at your booked time. We check Mi Account and Find Device status before anything that risks a reset, and inspect the charging port thoroughly for grease or metal dust build-up.
You get a fixed price before any work starts — no surprises at pickup.
Most screen, battery, and port repairs are completed the same day, including fingerprint sensor recalibration where applicable. Every repair is tested before handover.
We’d rather tell you not to spend money than sell you a repair you’ll regret. Here’s the honest breakdown:
| Situation | Worth repairing? |
|---|---|
| Redmi Note series or Mi flagship, screen or battery issue | Yes — repair cost is well under replacement value |
| Charging port clogged with grease or metal dust, otherwise fine | Yes — often a cheap clean or port repair, not a full replacement |
| Standard Redmi, battery health noticeably reduced but phone otherwise fine | Yes — a battery swap is cheap and restores the phone’s whole selling point for a long-shift job |
| Older or entry-level Redmi (under $250 new), screen cracked | Maybe not — repair cost can approach the price of a replacement at that tier |
| Phone locked with “Mi account locked” screen | We can’t bypass this — original account credentials are required, not a paid repair |
If you work in a workshop environment, a cheap silicone port cover or case with a port flap can meaningfully cut down on grease and dust getting into the charging port between shifts — a small habit that avoids a repeat visit.
We repair the full current and recent Xiaomi, Redmi and POCO range:
Models: Xiaomi 14 / 13 / 12 series, Redmi Note 13 / 12 / 11 series, Redmi 13C / 12C / 12, POCO X6 / X5 / F5 series, and older Xiaomi and Redmi models on request.
Repairs: screen & digitiser replacement, fingerprint sensor recalibration, battery replacement, USB-C charging port deep-clean and repair, back glass replacement, camera module replacement, speaker & microphone repair, Mi Account status checks prior to any reset, water damage diagnostics and cleaning, software troubleshooting and data recovery assistance.
Every price below reflects what we actually quote at the Underwood Marketplace kiosk, including for phones with grease and metal dust build-up that needs a proper clean before diagnosis — not a national average that assumes a light dusting of pocket lint. If a part isn’t in stock at Underwood on the day, we’ll tell you before you book, not after.
| Repair | Redmi (Standard/C-Series) | Redmi Note / POCO | Xiaomi Flagship |
|---|---|---|---|
| Screen replacement | $89 – $139 | $149 – $229 | $229 – $349 |
| Battery replacement | $69 – $89 | $79 – $109 | $99 – $139 |
| Charging port deep-clean / repair | $49 – $69 / $69 – $89 | $49 – $69 / $79 – $99 | $49 – $69 / $89 – $129 |
| Back glass replacement | $69 – $99 | $89 – $119 | $109 – $159 |
| Camera module | $79 – $109 | $99 – $139 | $119 – $179 |
| Water damage diagnostic & clean | Free diagnostic — cleaning from $59, parts quoted separately if needed | ||
Prices are typical ranges based on model and part availability. Final price is confirmed after your free in-store diagnostic — we never charge more than the quote we give you.
Xiaomi and Redmi screen repairs at Case Indulgence Underwood range from around $89 for an entry-level Redmi up to $349 for a Xiaomi flagship. The exact price depends on the model and part availability.
Fine metal dust mixed with grease residue from a workshop environment packs into a USB-C port more aggressively than ordinary pocket lint, and it’s genuinely harder to clear without a proper deep-clean. Case Indulgence Underwood sees this pattern regularly given the service departments along the local dealership strip.
A Mi Account lock happens when a phone is factory reset while still signed into a Mi Account with Find Device enabled, similar in concept to Find My iPhone. It cannot be bypassed by a repairer, including us — only the original account username and password can unlock it, so it’s worth disabling Find Device before any reset.
Yes, a deep-clean is often enough to resolve a grease-and-dust-affected port without needing a full port replacement. We check during the free diagnostic and only recommend the more expensive repair if the port itself is genuinely damaged.
Most Xiaomi and Redmi screen and battery replacements are completed the same day, often within 1–2 hours, at Case Indulgence Underwood, including fingerprint sensor recalibration.
We use genuine OEM-grade parts sourced through certified suppliers for all Xiaomi and Redmi repairs, and we’ll tell you upfront which parts are used for your specific model.
Booking online is the fastest way to get seen, since it lets us check part availability before you arrive. Walk-ins are welcome too, but booked customers are seen first.
