A sudden power outage is a fairly common problem that can happen to both Android and iPhone devices. This condition not only causes discomfort during use but also poses a risk of hardware damage if not promptly fixed.
Bottled, damaged batteries
Battery is the leading cause of sudden power outages. After a period of use, the battery will lose performance and will no longer be as stable as at first.
The phone can be turned off even with 20 30% battery.
The battery drops off quickly, heats abnormally or does not come on after turning off.
Using an unreal charger can also damage the battery faster.
Recognization signs: Use battery testing apps like AccuBattery ( Android) or check in the Pin > battery status ( iPhone).
application or software errors
Incorporated software or applications can cause system conflicts, leading to the phone turning off on its own.
Install too many heavy or unknown applications.
Some background apps are constantly overloading CPUs and RAM.
The operating system update was not complete.
Solution: Start the phone in safe Mode for check. If the device works normally in this mode, the error may lie in the third-party application.
The machine overheats
Temperature is a factor that directly affects the stability of the phone. When the device is too hot, the system will automatically turn off to protect the hardware.
Reasons for the machine being too hot:
Play heavy games, watch videos continuously for a long time.
Use your phone while charging.
Leave the device in the sun or high temperature environment.
Symptoms: The back is hot, the engine is slow, it automatically turns off halfway and cannot be restarted immediately.
Outdated operating system or unofficial rom
The old operating system may no longer be compatible with new software, leading to a system failure.
Some users install a custom ROM to experience the new feature, but this ROM is often unstable and prone to errors such as hanging up, suddenly turning off power.
Note: Only install the official ROM from the manufacturer and update the software periodically.
hardware errors
hardware errors are often more serious and can occur when the phone is hit hard, in water, or has been improperly repaired.
Components such as source ICs, mainboards or sockets are loose and broken.
The repaired machinery that is not reputable may be further damaged.
Identification signs: The machine suddenly shuts down many times, making it difficult to re- start, or sometimes not fully up.
viral or malware infections
phones that install applications from unknown sources are at risk of malware infection. These software can interfere deep into the system, causing unusual errors, including sudden power outages.
Solution:
Scanning viruses using reputable viral anti- virus software.
Delete strange applications of unknown origin.
