Short answer, no. Time for a new one, I reckon.
What doesn't the warranty include?
While the Apple warranty means that your iPhone is covered for a year from the day you purchase it, Apple states that its Limited Warranty for iPhone excludes coverage for "damage resulting from accident, disassembly, unauthorized service and unauthorized modifications." The warranty may also be void if the Liquid Contact indicator in your product has been triggered.
Apple states in the legal document that the warranty does not apply in the following cases: "(a) to consumable parts, such as batteries or protective coatings that are designed to diminish over time, 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; (c) to damage caused by use with another product; (d) to damage caused by accident, abuse, misuse, liquid contact, fire, earthquake or other external cause; (e) to damage caused by operating the Apple Product outside Apple's published guidelines; (f) to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider ("AASP"); (g) to an Apple Product that has been modified to alter functionality or capability without the written permission of Apple; (h) to defects caused by normal wear and tear or otherwise due to the normal aging of the Apple Product, or (i) if any serial number has been removed or defaced from the Apple Product."
However, Apple does note that even an iPhone that is ineligible for warranty service may be eligible for Out-of-Warranty (OOW) Service (for a price). That is as long as it meets the requirements of the OOW service. Certain damage is ineligible for OOW service notes Apple, including: "Catastrophic damage, such as the device separating into multiple pieces, and inoperability caused by unauthorized modifications."
