What Actually Voids Your Phone Warranty — And What Doesn't

June 2026 · 5 min read · By Curbside Phone Tech

Manufacturers have a financial interest in telling you everything voids your warranty. US law gives you more protection than Apple's fine print suggests. Here's the real picture.

Warranty void: fact vs. fiction

ActionVoids Warranty?
Third-party screen repairNo — under Magnuson-Moss Warranty Act
Third-party battery replacementNo — same US law protection
Using a non-Apple chargerNo
Applying a screen protectorNo
Accidental damage (cracked screen)Yes — Apple warranty covers manufacturing defects, not drops
Water damage (beyond IP rating)Yes — physical damage exclusion
Jailbreaking iPhonePartially — Apple can deny coverage for software issues only
Rooting AndroidPartially — can void software-related warranty claims
Tampering with internal components yourselfYes — DIY opening and damaging components

The Magnuson-Moss Warranty Act — your protection

This US federal law from 1975 says that a manufacturer cannot make warranty coverage conditional on the consumer using the manufacturer's own parts or service. Apple cannot legally void your warranty on your iPhone display just because someone other than Apple replaced the battery. They can only deny a warranty claim if they can demonstrate that the third-party service directly caused the specific failure you're claiming.

In practice: if you get a battery replaced at Curbside Phone Tech and then the camera stops working a week later, Apple cannot attribute that camera failure to the battery replacement. They'd have to prove a causal connection that doesn't exist.
