Sensor not working

This is the most common problem and can be due to various causes, such as impact when falling. To accurately diagnose them, you need to understand how to check the iPhone for malfunctions. In general, they work like this:

  1. Update to the latest version of iTunes (if necessary).
  2. Open the program and click on the "Help" section in the top panel.
  3. Next, go to "Run diagnostics".
  4. Select one or more tests and click "Next".
  5. Upon completion of the check, copy the results to the clipboard.
  6. Paste them into Word, Notepad, or another text editor.

Next, you need to see what kind of diagnostics are performed. The following tests indicate problems with the screen:

  • on broken pixels - they are bright enough, so you can also determine visually on the screen;
  • 3D Touch - screen performance option in percent (up to 100%);
  • on the screen sensor - identification of non-working parts;
  • multi-touch - the ability to control the touch of several fingers, for example, to enlarge a photo.

If the iPhone burned out

Another test is related to how to understand that the iPhone burned out. In this case, the problem is related to a malfunction of the controller, which will have to be replaced. This is the name of the microcircuit, which is located on the gadget's board itself. If it stops working normally, you have to disassemble the entire device, which is quite difficult to do on your own.

There are several ways to diagnose an iPhone for a broken controller. You can determine that the device has burned down by the following signs:

  • the device quickly loses its charge, even if it just lies idle;
  • the amount of charge is clearly displayed incorrectly, for example, when connected to charging, the indicator may not increase, but, on the contrary, decrease;
  • The iPhone does not identify the original cable, but at the same time it identifies its cheap counterpart;
  • the gadget does not charge at all;
  • it charges, but only after a preliminary shutdown.

Battery check

Problems with charging do not necessarily indicate a breakdown of the controller. Faults can also be related to the battery. To check it, just follow these steps:

  1. Go to settings, then to the "battery" section.
  2. Check battery capacity.
  3. Activate the optimized charging option to increase battery life.
  4. Check the condition and number of cycles of the battery.
  5. Run a stress test - that is, set the maximum load and evaluate how quickly the battery runs out.

All these data must be correlated with the parameters presented in the model description. For example, normal battery life is about 15-20 hours. If, for example, in just 2 minutes when watching a video, the battery loses 10-20%, this clearly indicates a malfunction and the need for replacement.

Checking the originality of parts

If there is a suspicion that parts could have been replaced in the gadget, you need to start checking. As a rule, fake LCD display. Therefore, for diagnostics, it is necessary to disassemble the iPhone and compare the parameters with the original spare part.

  1. A fake has a warranty sticker or a supplier's stamp on the frame. Instead of a frame, it can also be seen on a cable or on a backlit sticker. Normally, there should be no sticker or stamp at all.
  2. The original display has an Apple logo or a barcode on the cable, while the fake one does not.
  3. You can also notice the iridescent tint on the camera lenses on the original. Fakes don't have it.
How to diagnose iPhone

If it is not possible to clarify the data, you can contact the specialists. They carry out diagnostics using software. In this case, the result will be 100%: you can definitely say whether the screen is original or not.

In other cases, for example, special programs are also used to check a non-working camera. Moreover, it makes sense to contact the service center only if the gadget is intact, not injured due to a strong fall or a long stay in the water. In these situations, with a high probability, the iPhone is beyond repair.
