Smartphone repair Warsaw — screens, batteries and logic boards
We repair smartphones across the full range — from screen, battery and charging-port replacement to logic board repairs (microsoldering) that ordinary shops won't take on. Always a quote before the repair, with a specific timeframe given at quotation — simple repairs often take 1–3 working days. Our workshop is in Warsaw's Praga-Południe (Grochów) district, and you can also send your phone by courier from anywhere in Poland.

Screen, battery and charging-port replacement
A fully-fledged part of what we do, not an add-on: screens, batteries, charging ports, cameras, back glass. Original or good-quality parts and a 12-month warranty on every repair.

The timeframe depends on the fault and parts availability — we aim to turn simple repairs around quickly, usually within 1–3 working days; when a part has to be ordered, it takes longer. We give you a specific timeframe with the quote, and the diagnosis is always free. Call: 512 800 030
We repair logic boards when others say: it can't be done
Most shops only swap ready-made modules — the screen, the battery, a whole “complete” part. We work at board level: under the microscope, with a hot-air station and a microsoldering rig. These are repairs that can't be done in 30 minutes at a counter — and that's exactly why they end up with us.
Power and charging circuit
The phone won't charge, won't hold a voltage or gets hot while charging. We repair the power (PMIC) and charging circuits, including Tristar/Tigris on iPhone.
Charging port
Replacing the USB-C and Lightning port when the cable sits loosely or crookedly, or the phone won't detect charging at all. Soldered to the board, not “glued on”.
Repair after liquid damage
Ultrasonic cleaning of the board, removing corrosion and salt, restoring damaged traces. We act before electrolysis destroys further chips.
Short circuits and “no power”
The phone won't turn on, gets hot in one spot or “drains” the battery. We locate the short circuit with thermal imaging and bring the board back to life.
Backlight, audio, signal
A dark screen on an otherwise working phone, no sound, no signal after a repair. We repair the backlight and audio circuits and the network section on the board.
These are advanced repairs carried out under the microscope — they take time and precision, which is why we don’t promise them “on the spot”. We do them properly, once and well. After the free diagnosis we give you a realistic timeframe and cost.
From older models to the latest releases
We repair iPhones and Android phones from every popular brand — from screen and battery replacement to logic board repair. Expand your brand to see what we do.

Sony Xperia
Xperia 1 · Xperia 5 · Xperia 10 · older XZ / XA / Z series
Servicing Sony phones is a rarity — many shops refuse them for lack of parts. We take Xperias in the full range: screen, battery, USB-C port, board repairs. Sony parts often have to be ordered, so we give you a specific timeframe with the quote.

Xiaomi (13 / 14 / 15 series, Mi, Ultra) · Redmi Note · POCO

Huawei P / Mate · HONOR · Nothing Phone
Screens, batteries, ports and board repairs — including Huawei models without Google services. After the free diagnosis we will tell you honestly what can be done for your model.

Why CSE Poland
From a screen replacement to logic board repair
We take in phones with cracked screens as well as ones other shops refused to repair. The same workshop, the same approach: a quote before the repair and honest work.
The full range of repairs
Screen, battery, charging port, back glass — and when the fault sits deeper, microsoldering and logic board repair. We don't send you to “another workshop”, because we are that workshop.
A quote before the repair
The diagnosis and quote are free. We only start work after your approval — you know the cost and the timeframe before we do anything.
Confidentiality of your data
The photos and messages on your phone are private — and that's how we treat them. A confidentiality clause, GDPR compliance, and your phone never leaves our workshop.
Equipment and experience
A microscope, a hot-air soldering station and tools for BGA-level work. A workshop equipped for repairs that leave an ordinary kiosk helpless.
Honest diagnosis
If a repair isn't worth it, we'll say so openly and advise what to do next. We don't push services we wouldn't buy ourselves.
Warranty and VAT invoice
Every repair is covered by a 12-month warranty on the work carried out. We issue VAT invoices — we serve both individuals and businesses.

Got a question
about phone repair?
We've gathered answers to the questions we hear most often from owners of phones with cracked screens, weak batteries and logic board faults. Didn't find your answer?
Call: +48 512 800 030How much does a phone repair cost?
The cost depends on the model and the type of fault, which is why the diagnosis and quote are free. We give you the exact price after examining the phone, before we do anything — we only start work after your approval. Call: 512 800 030.
How long does a phone repair take?
The timeframe depends on the fault and parts availability. Simple repairs — screen, battery, charging port — we aim to turn around quickly, usually within 1–3 working days. When a part has to be ordered, it takes longer, sometimes up to 2–3 weeks. We give you a specific timeframe with the quote.
Will a repair void my warranty?
If your phone is still under the manufacturer's warranty, its terms usually require repairs at an authorised service centre — in that case it's best to claim through the seller. Most phones that come to us are out of warranty or have damage the warranty doesn't cover (liquid, drops). Every repair we carry out comes with our own 12-month warranty.
Can you replace just the screen or the battery?
Yes — replacing screens, batteries, charging ports, cameras, speakers and back glass is everyday work in our shop. We use original or good-quality parts, and every repair comes with a 12-month warranty.
Do you repair logic boards and do microsoldering?
Yes, that's our specialism. We do microsoldering and BGA chip replacement, repair power and charging circuits, USB-C and Lightning ports, backlight and audio ICs, and rebuild damaged traces. We work under the microscope, at the level of individual chips.
Do you repair liquid-damaged phones?
Yes. We clean the board ultrasonically, remove corrosion and repair damaged traces and chips. Time matters — don't charge a liquid-damaged phone and don't dry it on a radiator; bring it or send it to us as soon as possible.
What about the confidentiality of my data and photos?
Your data is private and that's how we treat it. We are bound by a confidentiality clause and GDPR compliance, and your phone never leaves our workshop during the repair.
How do I send my phone from another city?
Order a courier online — a DPD courier will collect the phone from your door (20 PLN one-way). You can also drop the parcel at an InPost locker yourself (WAW47A). After the free diagnosis we call you with a quote, and after the repair we send the phone back under warranty. Order a courier online.
