Quick Answer
Why does my phone keep restarting?
A phone that keeps restarting may have a faulty app, low storage, damaged software, a weak battery, overheating, charging problems, a stuck power button or internal hardware damage. The best clue is usually when the restart happens.
01
Understanding the fault
Why Does My Phone Keep Restarting by Itself?
A phone may restart unexpectedly when its operating system becomes unstable, power delivery is interrupted or an internal component stops working correctly. Users often describe the same problem as a phone that keeps rebooting, randomly restarts or keeps turning off and back on.
One restart during a normal system update may be expected. Repeated or unexplained restarting is different. The timing of the fault can help separate a software problem from a battery, charging or hardware issue.

Most common problems
8 Reasons Your Phone May Keep Restarting
Faulty Apps
Recently installed or unstable apps can crash important Android or iOS processes.
App conflict
Low Storage
Very little free space can interfere with updates, temporary files and system operations.
Storage issue
Software Errors
Failed updates or corrupted system files may cause crashes, random reboots or a boot loop.
OS problem
Weak Battery
A degraded battery may fail to supply stable power, causing shutdowns and automatic restarts.
Power instability
Overheating
Excessive heat may trigger protective shutdowns or reveal battery and hardware problems.
Temperature
Charging Fault
Cable, adapter, charging port or power-management faults may trigger restarts during charging.
Charging system
Power Button
A stuck or damaged button can repeatedly trigger shutdown and restart commands.
Physical fault
Hardware Damage
Drops, liquid damage or board-level faults can cause persistent restarting.
Internal damage

Software-related restarts
Why Does My Phone Keep Restarting After an Update?
If the problem began immediately after a software update, the restart may be linked to an incomplete installation, corrupted system files, insufficient storage or an app that no longer works correctly with the updated operating system.
1
Check updates
Install pending system updates.
2
Update apps
Outdated apps may conflict.
3
Check storage
Make sure free space remains.
4
Test Safe Mode
Check for third-party app problems.
Battery Check
Can a Bad Battery Cause My Phone to Keep Restarting?
Yes. An ageing or damaged battery can become unable to provide stable voltage. When the phone suddenly needs more power, it may switch off and restart.
- Restarts at a similar battery percentage
- Battery percentage suddenly drops
- Battery drains much faster than normal
- Phone shuts down during demanding tasks
- Rear cover or battery appears swollen

Unstable Power
Battery safety warning
If your battery is swollen, stop charging and using the phone. Do not press, puncture or bend it. Arrange a professional inspection instead.
04
Power and charging
Why Does My Phone Keep Restarting While Charging?
If the phone mainly restarts when connected to power, the charging system becomes a strong suspect. The cable, adapter, charging port, battery or internal power circuit may be involved.

Startup Problem
What Is a Boot Loop on a Phone?
A boot loop happens when the phone starts, reaches the logo or loading screen, fails to complete startup and restarts again.
A phone stuck on the Apple logo, Samsung logo or Android startup screen may have corrupted software, a failed update, storage failure, power problems or damaged hardware.

Frequently Asked Questions
Clear answers to common questions about random phone restarts, batteries, software and repair.
↻
Restarting...
01 Why does my phone keep restarting by itself? +
A phone may repeatedly restart because of faulty apps, low storage, software corruption, battery degradation, overheating, charging faults, a stuck power button or internal hardware damage.
02 Can a bad battery cause my phone to keep restarting? +
Yes. A degraded battery may fail to provide stable voltage, particularly when the phone suddenly requires more power. This can cause shutdowns and automatic restarts.
03 Can low storage cause a phone to restart? +
Extremely low storage can interfere with system processes, app updates and temporary files. Freeing space may help if the restarting is software-related.
04 Why does my phone keep restarting after a software update? +
An interrupted update, corrupted system files, insufficient storage or an incompatible app can sometimes cause repeated restarting after a software update.
05 Why does my phone keep restarting while charging? +
Charging-triggered restarts can involve the cable, adapter, charging port, battery or internal power-management components.
06 Why is my phone stuck on the logo and restarting? +
Repeatedly reaching the startup logo and restarting is commonly called a boot loop. Failed updates, corrupted software, storage issues or hardware problems may be responsible.
07 How do I know if constant restarting is software or hardware? +
Problems beginning after an update or app installation often point toward software. Restarts following physical damage, liquid exposure, charging faults, overheating or battery swelling make hardware issues more likely.
08 When should I get a phone that keeps restarting repaired? +
Professional diagnosis is sensible when repeated restarting continues after safe troubleshooting, the device becomes unusually hot, restarts while charging, has physical damage or cannot complete startup.
09 Where can I get a restarting phone checked in Abingdon? +
Galaxy Techno provides phone diagnostics and repair services in Abingdon for software, battery, charging, startup and internal hardware problems.
