Do Phone Repairs Come
With a Warranty?

One of the first questions to ask any repair shop is: what warranty do you offer? A warranty is a sign of confidence in the work and the parts used. Shops that fix phones with cheap components or inexperienced technicians tend to offer no warranty at all — or make it so difficult to claim that it's effectively worthless.

Here's what to look for, what a good warranty covers, and what ours looks like at Mobex.

Do All Phone Repair Shops Offer a Warranty?

No — and this is an important distinction. Many market stalls, informal repair services, and some smaller shops offer no warranty at all. Others offer a token 30-day guarantee that barely covers the time it takes for a low-quality screen to develop faults.

A reputable shop with quality parts and skilled technicians will confidently offer a 90-day to 1-year warranty as standard. If a shop can't tell you clearly what their warranty covers, that's a red flag.

What a Good Repair Warranty Covers

A proper warranty on a phone repair should cover the replaced part and the workmanship — meaning if the part fails within the warranty period due to a fault with the component itself or how it was fitted, the shop will fix or replace it at no cost.

Scenario	Covered?
Screen develops dead pixels within warranty period	✓ Yes — part fault
Screen stops responding to touch after fitting	✓ Yes — workmanship or part fault
Battery doesn't hold charge after replacement	✓ Yes — faulty replacement battery
Screen cracked again after dropping the phone	✗ No — accidental damage
New screen damaged in a subsequent drop	✗ No — accidental damage
Phone water damaged after repair	✗ No — accidental damage

The distinction is clear: a warranty covers defects in the part or the fitting, not damage caused by the customer after the repair is completed.

Does Repair Void Your Manufacturer Warranty?

This is a concern many people have, particularly with iPhones. The honest answer is: in most cases, your manufacturer warranty has likely already expired by the time a phone needs a third-party repair. Apple's standard warranty is 1 year; AppleCare+ extends it to 2 years. Most people seeking independent repairs have phones that are 2+ years old.

For phones still under manufacturer warranty, a third-party repair can technically void it — though this varies by country and warranty terms. In the UK, consumer rights under the Consumer Rights Act 2015 provide additional protections beyond manufacturer warranties. If the phone had a fault before repair, that doesn't change your rights.

What to Ask Before Booking a Repair

• How long is your warranty? — anything less than 90 days is a yellow flag
• Does it cover parts and labour? — both should be included
• What parts do you use? — OEM-grade or manufacturer-equivalent parts have lower failure rates than generic budget parts
• Can I see the warranty in writing? — a receipt stating the warranty terms is reasonable to expect

Why Warranty Length Matters

Screen and battery faults often take time to manifest. A low-quality screen might display fine for the first month and then develop discolouration, backlighting issues, or touch inaccuracy by month three. A battery replacement with a weak cell might hold charge well initially but degrade much faster than a quality replacement. A 30-day warranty won't protect you against these scenarios — a 1-year warranty will.
