When iPhone 4 won't turn on
Everything that exists on Earth is subject to the process of aging, wear and tear. When a cellular device breaks down, it is always an unpleasant moment for the owner. Since the modern dependence of a person on means of communication is incredibly large and is due to many factors of everyday life. The reasons why the iPhone 4 does not turn on can be incredibly many, we will consider the main ones in this article.
What to do if iPhone won't turn on?
If the phone has not been subjected to shock, mechanical stress and has not become a victim of "waterprocedures", first of all, make sure that the battery is active. It is quite simple to do this. Connect a known-good charger to the phone. If a graphically displayed charging process appears on the screen, it means that the battery has run out. In the case when there is no reaction to the connected charger, you have to remove the back cover in order to get full access to the battery of the device. In a situation where the iPhone 4 does not turn on, we can talk about the loss of the starting pulse of the battery. This phenomenon is most often observed in phones that have not been used for a long time. As a result, it becomes necessary to force the charge on the battery, bypassing smartphone devices. A universal frog-type charger will cope with this task perfectly. Opening the back cover and dismantling the battery is elementary. The only complication is that you need to have special screwdrivers for iPhone 4 ". Since the bottom end screws are star screw and a Phillips screwdriver is needed to remove the battery cable retainer.
Bringing the battery back to life
Unscrew the two screws from the bottom of the case, slide up the cover of the device.
Then, remove the two bolts from the short battery cable retainer and disconnect it from the motherboard. Now, install universal charging on the battery terminals (two extreme contacts); 2-3 minutes will be enough to "revive" the battery. Assemble the device and connect the original power supply. If still notthe iPhone 4 turns on, a visit to the service center cannot be avoided. Because subsequent self-repair at home can be deadly for your mobile device. Don't skimp on qualified help. The phone is more expensive when you consider the risk of unconsciously destroying the iPhone through illiterate actions.
In conclusion
In some cases, the problem may be due to the failure of one of the multiple components of the system: the processor, power controller, flash memory, or any other microcircuit of the device. Therefore, it is advisable to seek help from professionals, since this type of repair can only be done with the help of special equipment.
