Understanding Automatic Restart and Switch Off Problems in Phones

I’ve seen this question everywhere: Why my phone is restarting automatically again and again? Before you can solve it, you need to know what’s causing it.

Common Reasons Your Phone Keeps Restarting

1. Using the Wrong Charger or Cable

Using a charger from another brand or a cheap third-party cable can cause damage. Some phones, including Xiaomi Redmi or Samsung, are sensitive to power input. They might shut off or restart to protect themselves from electrical issues.

2. Overheating

Phones have built-in temperature limits. When your device gets too hot, it auto-restarts to prevent hardware damage. Gaming, charging, and using heavy apps together pushes this limit quickly.

3. Old or Worn-Out Phone

As smartphones age, batteries weaken and hardware gets less reliable. This can trigger surprise shutdowns or restarts, even while you’re just browsing or texting.

4. Too Many Apps Running at Once

Running games, while chatting, calling, and charging, leads to overload. Your phone may restart in self-defense when it can’t keep up.

How These Problems Hit Your Phone’s Performance

Fast battery drain and sudden shut-offs
Heating up quickly, especially during multitasking
Reboots during calls, gaming, or charging
Apps crashing or phone freezing

Symptoms like these are classic signs your phone is caught in a restart loop. If you’re searching for “my phone keeps turning off and restarting Samsung” or “my phone keeps restarting and not turning on,” you’re seeing the results of one or more of these issues.

Step-by-Step Fixes: Stop Your Phone from Restarting Again and Again

Let’s break down practical solutions to stop your phone from restarting automatically. Whether you’re using Redmi, Samsung, Android or iPhone, most tips apply to all.

Enter Safe Mode to Test Your Phone

Safe mode starts your phone with only the essential apps, blocking third-party downloads. This helps spot if a bad app is behind the problem.

Here’s how to enter Safe Mode on most Androids, including Redmi:

Power off your phone completely.
Press and hold Power and Volume Up at the same time.
When the manufacturer logo shows, release only the Power button, keep holding Volume Up.
Use the Volume Down button to move to Safe Mode option.
Press Power to select.

Now your phone should say “Safe Mode.” Third-party apps won’t load. Use your phone for a few hours. If it doesn’t restart here, the issue probably comes from a downloaded app.

To exit Safe Mode:

Restart your phone as usual.

Remove Your SD Card and Clean Up Storage

SD cards can get corrupted or infected with malware, causing weird phone behavior. Here’s what you need to do:

Safely eject the SD card.
Go to your Gallery app, delete unneeded photos and videos.
Go to the Deleted Items folder and permanently erase files.
Use the File Manager app, check all folders for leftover junk or suspicious files, and delete them as well.

Removing all unnecessary files not only frees up space but can fix glitches and stop your phone from crashing.

Clear System Apps’ Cache

Software “junk” builds up as you use your device. Clearing caches helps clean out old data and bugs.

Go to Settings → Apps or Manage Apps.
Tap each major app (especially ones you use often) and click Clear Cache.
Never hit “Clear Data” unless you want to erase all info from the app!

Uninstall Suspicious or Recent Third-Party Apps

If your phone started acting up after a new install, delete that app:

Go to Settings → Apps.
Look for recent or suspicious apps. Uninstall them.
Only stick with trusted, official apps from the Play Store or App Store.

Update Your Phone’s Software

A lot of bugs, including auto-restart problems, get solved with software updates.

Head to Settings → About Phone → System Update.
Download and apply any updates.
Updates can contain bug fixes for “my phone keeps restarting over and over Android” or similar issues across many Android phones.

Disable Scheduled Power On/Off

Redmi and some other Android phones sometimes have a setting that auto-reboots the device at scheduled times. This can trip you up if you forget it’s turned on.

Open Settings.
Type “Schedule” into the search bar.
Tap Scheduled Power On/Off.
Turn off both “Power On” and “Power Off” schedules (toggle switches).
Tap OK to confirm.

If you keep getting stuck in random reboots, this feature could be active without you realizing it.

Force Reboot in Recovery Mode

A forced reboot clears out stubborn glitches—without deleting your files.

Power off your phone.
Hold Power and Volume Up together.
When the logo appears, let go of Power but keep holding Volume Up.
Use volume buttons to select Reboot to System, press Power to confirm.

This trick often stops those endless restart loops seen in guides about “my phone keeps restarting over and over Samsung,” as well as for Redmi and other Android models.

Reset Network Settings (no data loss)

Sometimes, network glitches can trigger restarts.

Go to Settings.
Search for “Reset.”
Choose Reset WiFi, Mobile Data, and Network Settings.
Enter your unlock code or PIN to confirm.

All your WiFi passwords and paired Bluetooth devices will be wiped, but your photos and files are safe.

Use Built-in Optimization and Virus Scan Tools

Most modern phones have a built-in security or optimizer tool.

Open Security or Optimization app (name may vary).
Run a full virus scan.
Tap Optimize or Clean Up to clear junk files.
Let the scan finish before using your phone again.

Built-in tools catch malware, clean cache, and can boost your phone’s speed. They’re safer than random apps from the Play Store.

Tweak Developer Options for Better Speed and Stability

Turning down animations and limiting background processes can stop some restart problems.

How to enable Developer Options:

Go to Settings → About Phone.
Tap the OS Version multiple times until you see “You are now a developer!”
Go back to Settings → Additional Settings → Developer Options.

Now, adjust these:

Set Window Animation Scale, Transition Animation Scale, and Animator Duration Scale to .5x or off.
Set Background process limit to “Standard limit.”
Make sure “Don’t keep activities” is turned off.

These steps reduce system strain and can make your phone run smoother.

When Software Fixes Aren’t Enough: Battery and Professional Help

If you’ve tried everything and the problem stays, it could be the battery. Here’s how to tell:

Battery drains faster than normal, gets hot, or phone restarts without warning.
Phone sometimes shuts off even when charge shows 30% or higher.

A bad battery is the root cause behind many “Why my phone is restarting automatically again and again Samsung” or Redmi issues. Get the battery checked or replaced at an authorized service center. Always back up your files before service.

If you reach this stage and your phone keeps restarting and not turning on, don’t waste time—professional repair is your best option.

Best Practices: Keep Your Phone from Restarting Again

Now that you’ve fixed the issue, how do you keep it from coming back?

Avoid multitasking heavily while charging.
Use official chargers and good-quality cables.
Clear cache and junk regularly.
Delete unused apps and large files every month.
Always keep your phone updated to the latest software.
Run periodic virus scans using the official security or optimization tool.
Don’t let your phone overheat. Avoid using it in hot sun or on a bed where heat can’t escape.

A little care goes a long way—these tips help for all phones, not just Android.
