The iPhone is a popular phone, a true multimedia center. Unfortunately, sometimes, for various reasons, it refuses to turn on. In some cases, the problem can be solved on your own, in others you will have to contact the service center.
Battery breakdown
The most common cause of iPhone inoperability is battery malfunction, which can suddenly start to drain extremely quickly. This is due to a malfunction of the lithium-ion battery itself or a breakdown of the power controller. The battery can, moreover, refuse to charge and save energy when trying to recharge through a "left" non-original or just a faulty device.
You can check the battery operation yourself by connecting a high-quality charger to the iPhone, since extraneous chargers often provide poor power due to poor contact. If the iPhone started charging and "came to life", just purchase the original charger, this will allow you to avoid unnecessary worries in the future. If nothing happens anyway, the battery itself or the power controller may be damaged. Controllers often break down when the device is plugged into car chargers.
In this case, you will have to contact the service center. Since you need to unmount the device to replace these parts, it is better not to do this at home and entrust the procedure to specialists. They check the energy retention time using a special device, after which they change the necessary part - a battery or battery, assemble the phone and return it to the owner. This procedure does not take much time.
Broken motherboard
Sometimes the iPhone does not turn on due to damage to the motherboard, the operation of the entire device as a whole depends on it. The motherboard contains the processor, RAM, storage, and connectors. It is rather difficult to determine without diagnostics which part of this device is out of order. Most often, its breakdown is the result of complex complex processes. The reason for the failure of iPhone motherboards is often mechanical damage or water ingress into the phone. Symptoms that the motherboard is malfunctioning include frequent reboots, problems with sound, or simply phone refusal to turn on.
Unfortunately, Apple does not supply iPhone components to the aftermarket. Therefore, the motherboard can only be replaced at service centers. This procedure usually takes place in the presence of the client. The specialist replaces the original board and checks the phone's functionality.
