IPhone does not turn on: what is it related to and how to fix the situation

Sometimes, on a far from perfect day the owner is faced with the fact that his iPhone does not turn on. Usually this happens as follows: the device was turned off, and it can not be turned on, because there is no reaction to pressing the power button. The first thing to do is connect the device to the charger and leave for half an hour alone. When the time passes, press the Power and Home buttons simultaneously in the charging mode and hold them for at least 15 seconds. Maybe the problem will be solved at this stage, but if, despite the actions taken, the iPhone does not turn on, it will have to be carried to the service center for diagnosis and repair.

What is the cause of trouble? And how much will it cost? There are several options. Let's try to figure out what can cause such a nuisance, and what to do in case the iPhone does not turn on. By the way, it can happen with a brand new device, and with a phone that was released in 2008.

1. The first battery is under suspicion. It is she who fails most often. And for old devices usually the battery just sits down, and iPhone 3g does not turn on mainly because of factory rejection, allowed during the assembly of the battery. Despite the cost and good quality of most of the batteries, production is never complete without marriage, especially as these parts for phones are manufactured in China. If it is determined that the marriage is the cause of the problems, the device must be replaced. If the battery simply outlived its life and does not cope with the load, you can replace it with a battery with increased capacity. It will cost about 2000 rubles. It's probably not the battery, but the charger. Most often they are not repaired, but simply replaced. The original "charging" for iphone will cost 700 rubles or more. If both the charger and the battery are OK, but the unit does not charge, the bottom loop may be damaged. Its replacement will cost in the amount of 1600 to 2600 rubles, depending on the prices of the service center.
2. The next most popular problem is mechanical damage. Remember, maybe the iPhone does not turn on because it was dropped recently? And not necessarily the day before - some breakdowns occur after a certain time, and not immediately. Even if the case does not have any damage, it does not mean that everything is well inside the device. So, what could happen as a result of the blow:
   • There was a breakdown in the supply chain, the repair will cost from 1500 rubles;
   • The charging controller burned, the replacement cost can vary from 1500 to 4500 rubles;
   • The motherboard has deteriorated, it can be changed for 7500 rubles and more.
3. The same problems can arise not from impact, but from getting into the body of moisture. It is not necessary to drop the phone into the water, it is enough to stay with it for a long time in dampness, for example, to walk after the rain on a wet park. Theoretically, it can be untwisted and dried, but it is almost always better to entrust it to specialists, because everyone can disassemble an iPhone, but not everyone can collect it back, and even so that there are no "unnecessary" details left.
4. The next reason that does not turn on iPhone 4, there may be problems with the firmware. This is due to the fact that there is no ideal software, there can always be some kind of flaw in it, which will lead to such trouble. If you turn on when you see the appearance of a brand name - an apple and nothing more, then, most likely, the device will have to be reflashed. To lose to you in this case, there is nothing, so before you go to the service center, try to restart your iPhone by simultaneously pressing the Power and Home buttons for 15 seconds. Maybe it will help. If it does not work, then the repair is done in RecoveryMode mode.

In general, an iPhone is not an item that can be repaired at home on the knee. In any case, you have to contact the service. Information about problems with the device and the cost of repairs will simply help you choose competent professionals with normal prices for services.
