  2. Software disruption.
  3. Battery failure or other failures in the power system.
  4. Violation of work due to temperature effects – overheating or hypothermia.
  5. Moisture ingress into the device.
  6. Phone memory overload.

Let’s take a closer look at each of the problems and their solutions.

Mechanical damage

Have you noticed that the phone spontaneously reboots, which the day before was dropped or hit on a hard surface? It is highly likely that the reason for the reboot is mechanical damage to the device’s filling. A breakdown may consist in a malfunction of the board or its components, and the separation of the loop contacts.

Checking smartphone loop contacts

In any case, to identify and eliminate the cause of the malfunction, the device must be disassembled. This is only worth doing if you have an ultra-thin soldering iron and a good supply of patience to thoroughly study the board and each contact of the system.

To disassemble the mobile phone and gain access to contacts, you need to unscrew and remove all panels. Next, inspect the board: are all the contacts of the loops well fixed.

If it was possible to identify the departed contact, it must be carefully soldered. Then assemble the device by screwing the panels in reverse order.

Battery or power system failure

Netizens claim that a common reason for frequent phone reboots is battery failure. A smartphone with a solid body and a non-removable battery will have to be carried to the service.

If self-diagnosis of the battery (battery) is possible, you should disassemble the device by removing the back cover. Then inspect the battery. It should be smooth, without swelling or depressions. The surface is without smudges, rust, stains. All of these are signs of a problem. If they are determined visually, it is necessary to replace the battery with a new one and check the operation of the smartphone.

Damaged smartphone battery

In addition to problems with the battery, the cause of the bug may lie in the oxidation or separation of the power contacts. To calculate the breakdown, you need to perform the following steps.

  • Clean the contacts with a cotton swab from dust and dirt.
  • Remove oxidation with alcohol, nail polish remover.
  • Apply an electric screwdriver to the contacts one by one, thus checking whether power is supplied to them: the indicator lamp will glow if everything is in order.

Temperature effects

Severe overheating or hypothermia can easily become a reason for constant reboots. If you suspect that this is the case, try to exclude exposure to too high or low temperatures on the phone.

If your smartphone overheats while charging, turn it off immediately and let it cool down. It is also important to remove the battery (if possible). When the device has cooled down, turn it on again and check if it works.

Often a reboot occurs due to a stuck power button. Try prying it with a pin or paperclip to remove the SIM card. If the cause of the malfunction is in this key, the reboots will stop.

Moisture ingress

Sometimes contact with moisture can cause the phone to restart in a circular fashion. If you have recently been exposed to rain or had other contact with liquid, it is important to dry your smartphone well. The most affordable and easiest way to do this is rice cereal.

To do this, disassemble the device: remove the cover, panels, remove the battery. All elements of the smartphone are placed in a container with dry rice so that the cereal completely covers them. Leave the device in the container for a couple of days. Rice is a highly absorbent material that will absorb moisture that has come into contact with the device components.

  Signs that moisture has entered the smartphone

After a couple of days, they take out a smartphone from the cereal, collect it and check its performance. If the cause of the malfunction was moisture, the problem should go away.

Overloaded memory

According to user reviews, overloaded device memory is often the cause of sudden reboots. To fix the problem, it is enough to clean the storage of photo and video files, remove unused applications.

Please also note that a lot of space in the smartphone memory is occupied by residual files of remote programs, phone software, and cookies. To perform high-quality cleaning, we recommend downloading and installing special applications on your phone, for example, Clean Master.
