I phone frame is chipping off from edges

Hi there deepachopra,

Thanks for taking the time to connect with is here in Apple Support Communities. We understand you're asking if scratches or chips in the enclosure on your iPhone are covered under warranty. We're glad you're here, and we can provide some guidance.

"This warranty does not apply: (a) to consumable parts, such as batteries, unless failure has occurred due to a defect in materials or workmanship; (b) to cosmetic damage, including but not limited to scratches, dents and broken plastic on ports;"

From what we can tell, the damage you're describing sounds like it may be cosmetic. Have a look at this link to learn more:

Take care!
