The phone won't charge
The most common cause is a problem with the socket where the power cord is inserted. Over time, the socket loosens in the case, the contacts oxidize and do not conduct current well, etc. The defect can be detected by inserting the cable into the socket and slightly wiggling it at the base. If the charging indicator periodically "comes to life" and "goes out", then you need to contact the service center to replace the connector in the phone.
It should be added that for a number of models it matters which side of the charger is inserted into the slot. The problem can arise if you constantly connect the recharge not correctly.
Charging does not work
The charger may also be the reason. Yes, the indicator shows that everything seems to be working, but in fact the phone is not charging. To check this, you need to take another charger. If recharging goes through it without problems, then the old one can be thrown away. If the process still stalls, then you need to contact the service department or buy a new device.
It is important to remember that the new charger must be from the same manufacturer as the phone. Even if the charging socket is identical, non-native charging may cause the phone software to malfunction. And this can render it completely unusable, for example, by causing a malfunction of the processor.
Other reasons
There may be other reasons as well. For example, the failure of the electronic components of the phone. Most often, the battery of the phone fails, which either exhausts its resource, or is damaged, for example, due to the fall of the phone.
The help of specialists will be needed even if the phone "sits down" due to a sound or a beep. This is due to a problem with the power amplifier and often happens after the unit is dropped.
Smartphone owners can fall prey to viruses that have infiltrated via Bluetooth or the Internet. In particular, the Carib virus "specializes" in quickly discharging the battery, which constantly activates Bluetooth, which leads to the devastation of the battery. To avoid this option, it is recommended to install an antivirus on your smartphone.
