How To Get the Most From Your iPhone’s Warranty

13. Battery problems. Apple’s 1-year warranty does cover defective batteries. What precisely constitutes a defective battery is difficult to establish. Should your iPhone be showing signs of battery trouble, you would best be served by arguing that the battery was defective, and not that it simply wore out. If your iPhone is exhibiting any other atypical behavior such as excessive heating while charging or inconsistent power monitoring, your argument will be much stronger. Apple estimates that an iPhone battery should last approximately 400 charges. If you are consulting an Apple Genius then you may want to mention approximately how often you charge your iPhone. As long as your iPhone is still under the warranty, poor battery life may be an avenue to demand a new iPhone.

14. Accelerometer problems. Many iPhone owners have reported problems with the built-in accelerometer. Anyone who uses their iPhone for gaming or frequently flips their iPhone on its side to view in landscape mode will know whether their iPhone’s accelerometer is functioning correctly. Be sure you are holding your iPhone vertically when rotating it; the accelerometer may not function correctly otherwise. Remember, it is based on gravity, so extraneous movement (i.e. walking, jogging, tilting, etc.) may confuse the accelerometer. However, if you genuinely believe your accelerometer may not be functioning correctly you should take your phone in to be replaced.

15. Ambient light sensor problems. The iPhone’s ambient light sensors are located near the top of the iPhone. To test whether the ambient light sensors are functioning get a bright flashlight and go to Settings à Brightness and turn the brightness down as far as it will go. Make sure auto-brightness is turned on. Press the sleep button at the top of the iPhone. Cover the ambient light sensors with your hand. Once the iPhone is asleep press the wake button and unlock the iPhone. Note the brightness of the screen. Then uncover the sensors and shine the flashlight at them. The screen should get a little bit brighter. If your iPhone is unresponsive you should consider taking it in for a replacement.

16. Proximity sensor problems. The proximity sensor makes sure that your iPhone turns its screen off when the phone is placed near your ear. If the proximity sensor is functioning properly, your iPhone should shut its screen off during phone calls when it is placed near your ear. The screen should turn back on when you move the phone away from your ear. Some owners have reported iPhones with defective proximity sensors. A defective sensor may fail to turn the screen on when it is removed from the phone call position, which results in an inability to use the touch screen while making a phone call. It also may not properly turn the screen off, which results in owners inadvertently hitting touch screen buttons while speaking on the iPhone. If you believe that your proximity sensor is not functioning correctly, you should bring your iPhone in for a replacement.

17. Dead or stuck pixels. If your iPhone’s screen has multiple dead or stuck pixels you should consider bringing your iPhone in for a replacement. At one point in time, Apple had a zero tolerance policy regarding the iPhone screens. That meant that even one dead or stuck pixel was grounds for replacement. However, more recently Geniuses have been reported to deny this policy. Whether it is technically legal for them to do so is a question that goes beyond the scope of this article because it depends on many factors specific to the iPhone owner (i.e. did an Apple representative tell you about this policy). If your iPhone has dead or stuck pixels you may still be able to have your iPhone replaced on these grounds. The Genius may refuse to replace your iPhone, but if you are persistent you may succeed. This is a grey area but it is certainly worth a try – especially if your iPhone has numerous dead or stuck pixels.

18. Mechanical buttons and switches. Although most physical problems are normally attributable to intentional or negligent acts by the iPhone’s owner, the switches on the iPhone may break or wear out. If they do wear out during the 1-year warranty period then it is probably due to some defect. However, be careful because an Apple Genius may be reluctant to replace your iPhone if shows evidence of other external physical damage. (See also AppleiPhoneApps.com)

So, you believe you have a legitimate warranty claim and you want to replace your iPhone. Now what do you do? First: be prepared to make several trips. Consider yourself especially lucky if you live near an Apple Store, as it will make this process much easier. You should also be prepared to argue your case: those Geniuses can be stubborn.
