What to Do for a Dead iPhoneby William McCoy
Discovering that your iPhone is dead is a frustrating experience; fixing the problem may range from simple to difficult. The iPhone can die for a number of reasons, including battery drain and being left in extremely high temperatures. Try a number of techniques to see if you can restore your iPhone, but if these fail, you may need to take it to a dealer to be fixed.
Upon noticing that your iPhone is dead, the first thing you should do is plug it in to see if it will recharge. You can charge your iPhone in one of two methods. If you have the wall adapter, plug the phone into the charging cable and wall adapter, and connect it to the wall. You can also plug your phone's cable directly into the USB port of a computer. Allow the phone to charge for 10 to 15 minutes, then attempt to turn it on.
Sometimes, you can restore a seemingly dead iPhone by completing a soft reset on the device. Press and hold the "On/Off" button, located on the top of the phone, while holding the "Home" button, which is located directly below the screen. Hold the two buttons down for roughly 5 seconds, then release them. The iPhone will power up again if this was the issue.
If your iPhone is old, or you've used it extensively, the internal battery may be dead. Apple says its iPhone batteries will last for 400 full drain and charge cycles; if you believe your phone's battery has had this many cycles, it's likely the battery has finally given up. If you are tech minded, buy a replacement iPhone battery and swap the old battery for the new one. If your phone is under warranty, take it to the dealer and have a technician install a new battery.
Sometimes, an iPhone will suffer from an internal problem that may cause it to lose function. In these cases, you cannot do anything to restore it except to take it to a dealer or repair shop and get the problem diagnosed and fixed. The problem could be the result of a faulty element in the iPhone, leaving it in a hot vehicle or dropping it in water. Whatever the case, a technician can often diagnose the problem for you; if the phone is under warranty, you may be able to have it fixed at no cost.
