Why Does My Phone Restart Automatically? Causes & Fixes
A phone that restarts by itself is one of the most disruptive faults a phone can develop — and one of the most misdiagnosed. Random restarts, scheduled reboots, and boot loops look similar but have entirely different causes. Factory resetting without understanding which one you have can cost you your data and leave the problem unsolved. This guide tells you exactly which type you have and what to do about it.

The Three Types of Automatic Phone Restart — Which One Do You Have?
Diagnosing automatic restarts correctly starts with identifying which category you’re dealing with. Each one has a different set of causes and a different set of fixes. Treating the wrong category wastes time and can make the situation worse.
Random Unpredictable Restarts
Happens without warning, irregularly — once a day, once every few days, or only under specific conditions like heavy use or low battery. Phone resumes normally after rebooting.
Causes: rogue app, failing battery, software crash, loose connector, overheatingScheduled / Regular Restarts
Restarts at roughly the same time every day or on a regular pattern. Phone works normally before and after. Many users mistake this for a random fault.
Cause: scheduled reboot feature enabled in settings — not a fault at allBoot Loop
Phone restarts repeatedly and cannot reach the home screen. Stuck on manufacturer logo or startup animation. Cannot be used at all in this state.
Causes: failed OS update, corrupted software, failed battery, hardware faultThe first step is identifying your type. If the phone restarts but reaches the home screen and works normally afterwards — you have Type 1 or 2. If the phone never reaches the home screen — you have Type 3. The rest of this guide addresses each type in detail.
Type 2: Check Whether Your Phone Has a Scheduled Reboot Enabled
Before assuming any restart is a fault, check your phone’s scheduled reboot setting. This is the most commonly overlooked restart cause — and the easiest to resolve.
Samsung Galaxy phones include a feature called Auto Restart (on older models) or Auto Reboot (on newer One UI). It’s buried in settings and occasionally enables itself after major software updates. On Samsung: go to Settings → Device Care → Auto Optimisation (or Settings → Battery & Device Care → Auto Optimisation) and look for a scheduled restart toggle. If it’s enabled, it may be set to restart the phone weekly or at a specific time daily. Disabling it ends the “random” restart immediately.
OPPO and OnePlus phones have a Scheduled Power On/Off feature at Settings → Additional Settings → Scheduled Power On/Off. Vivo phones have similar functionality at Settings → Battery → Scheduled Switch. Xiaomi (MIUI/HyperOS) has Settings → Battery → Scheduled On/Off.
iPhone does not have a native scheduled reboot feature — so if your iPhone restarts at roughly the same time every day, it’s almost certainly a software or hardware fault rather than a setting.
✅ Check This First — Takes 30 Seconds
Before reading further, check your scheduled power or auto-restart settings using the navigation above for your brand. If a scheduled restart is enabled and set to a time that matches when your phone restarts — disable it. Your phone’s “fault” was a feature the whole time. This resolves a meaningful proportion of “my phone keeps restarting” complaints at Mobile Connect Brisbane at no cost to anyone.
The Most Important Question: Is Your Restart Caused by Software or Hardware?
This distinction determines everything that follows. A software-caused restart can be fixed with app management, OS updates, or in severe cases a factory reset. A hardware-caused restart cannot be fixed by any software action — and attempting a factory reset on a hardware fault causes unnecessary data loss while leaving the problem unsolved.
How to Tell the Difference — The Restart Pattern Test
The way the phone restarts tells you almost everything about the cause.
| What You Observe | Likely Cause Type | Key Indicator |
|---|---|---|
| Phone restarts and resumes exactly where you left off — same apps open, same screen | Software crash | OS recovered cleanly from the crash; data was preserved |
| Phone shows brief black screen then boots fresh from the lock screen | Power fault — battery or hardware | Phone lost power completely rather than crashing; equivalent to pulling the battery out |
| Restart always happens when opening or using the same app | Rogue app crash | App is consuming resources until the OS terminates it and restarts |
| Restart always happens at low battery (20–30% remaining) | Battery voltage failure | Battery’s actual voltage drops below minimum threshold while percentage display still shows moderate charge |
| Restart happens during heavy use — gaming, video, navigation | Thermal shutdown or battery load failure | High processor load combined with heat or battery degradation exceeds threshold |
| Restart happens during or immediately after charging | Charging IC fault or battery fault | Voltage irregularity during charging triggers a power event |
| Restart started after installing a new app or OS update | Software conflict or corrupted update | Timing correlation strongly suggests software cause |
| Phone restarts even when idle with no apps open and good battery | Hardware fault — connector, board, or battery | No software activity to trigger a crash; power event from hardware |
Software Causes of Automatic Phone Restarts — and How to Fix Them
Cause 1: A Rogue App Is Crashing the System
A single poorly coded or corrupted app is the most common software cause of automatic restarts. The app consumes memory or processor resources until the Android or iOS system can no longer manage the load — at which point the OS terminates the app and restarts to recover a stable state. The restart is the OS protecting itself, not a phone fault.
The diagnostic test: does the restart correlate with using a specific app? Open your phone’s battery usage screen and check which apps have used the most power since the last charge. On iPhone: Settings → Battery → Battery Usage by App. On Android: Settings → Battery → Battery Usage. An app using dramatically more battery than others — particularly one installed or updated recently — is a strong suspect.
On Android, check Settings → Digital Wellbeing or Settings → Apps for any app showing unusual background activity. Uninstall or clear the cache of the suspect app and observe whether restarts stop. On iPhone, deleting and reinstalling a suspect app often resolves app-specific crashes.
Cause 2: Insufficient Storage Space
A phone with less than 10% of its total storage available becomes systemically unstable. The OS needs free storage space to write temporary files, system logs, and cache data during normal operation. When storage is critically low, write operations fail, which can cause system processes to crash and trigger a restart.
Check available storage: iPhone → Settings → General → iPhone Storage. Android → Settings → Storage. If you’re below 10% free, clear unnecessary photos, apps, and downloads before assuming a hardware or software fault. This is particularly common on budget Android phones sold in Australia with 64GB storage that fill up quickly.
Cause 3: A Failed or Corrupted OS Update
Phone operating system updates occasionally introduce bugs that cause restart loops or random reboots — particularly in the days immediately following a major update. If your phone started restarting after an iOS or Android update, the update itself is the most likely cause.
On iPhone, check whether Apple has released a subsequent patch (shown in Settings → General → Software Update). Installing the patch typically resolves update-caused restarts. On Android, the equivalent process varies by brand — check your brand’s software update channel for any hotfix releases after the update that caused the problem.
Cause 4: OPPO, Vivo, and Xiaomi Aggressive Battery Optimisation
This is the brand-specific cause that no Brisbane competitor mentions. OPPO (ColorOS), Vivo (FunTouch OS / OriginOS), and Xiaomi (MIUI / HyperOS) all include extremely aggressive battery optimisation systems that kill background processes more forcefully than stock Android. In some edge cases — particularly when memory pressure is high in Brisbane’s heat-induced thermal throttling conditions — these optimisation systems trigger a restart to clear memory rather than simply killing individual apps.
If you own an OPPO, Vivo, or Xiaomi phone that restarts seemingly randomly: go to Settings → Battery → Battery Optimisation (or App Management → Battery). Find apps set to “Optimise” or “Restrict” that shouldn’t be — particularly system apps and your main apps. Set your critical apps to “No Restrictions.” Also check Settings → Additional Settings → Developer Options (if enabled) and look for background process limits that may have been set too aggressively.

Hardware Causes of Automatic Phone Restarts — the Ones Software Fixes Won’t Resolve
Cause 1: Failing Battery — the Most Common Hardware Restart Cause
A degraded battery is the most common hardware cause of automatic phone restarts — and the most important to identify correctly, because a failing battery that causes restarts will not be fixed by any software action whatsoever.
Here’s the mechanism. As lithium-ion batteries age, their capacity decreases and their internal resistance increases. A battery with significantly increased internal resistance has a compressed voltage curve — meaning its voltage drops steeply at lower charge levels rather than declining gradually. When the phone draws a burst of current for a demanding task (opening a camera, receiving a call, GPU processing in a game), the battery’s actual voltage momentarily drops below the minimum threshold the phone’s power management system requires. The system registers this as a power failure and triggers a restart — even if the battery percentage display still shows 20%, 30%, or even 40% remaining.
This is why phones with failing batteries frequently restart at seemingly adequate battery levels. The percentage display shows one thing; the actual instantaneous voltage tells a different story.
⚠️ How to Check Whether the Battery Is the Restart Cause
- Pattern check: Does the phone restart during demanding tasks (gaming, camera, navigation) or at low battery (below 30%), but not while idle on charge? This pattern strongly indicates battery voltage failure under load.
- iPhone battery health: Settings → Battery → Battery Health & Charging. Below 80% capacity is Apple’s service threshold — but restart-causing voltage drops can occur at 82–85% in Brisbane’s heat. If you’re below 85% and experiencing restarts, battery replacement is the most likely solution.
- Android battery health: Samsung Members app → Support → Error Reports → Diagnostics → Battery. For other Android brands, download AccuBattery (free on Google Play) and charge to full — AccuBattery measures actual capacity versus rated capacity after a full charge cycle.
- The charger test: Does the phone restart less frequently when plugged in? A battery fault often reduces restart frequency on charge because the charger provides a stable voltage supplement. If restarts stop when plugged in but resume on battery, the battery is almost certainly the cause.
Cause 2: Swollen Battery — Urgent, Not Just a Restart Issue
A swollen battery causes automatic restarts through a different mechanism than simple capacity degradation. As a battery cell generates gas internally (due to degraded electrolyte or overcharging damage), the cell physically expands. This expansion creates pressure on the internal components around it — particularly the motherboard connectors and the flexible cable assemblies that connect the battery to the charging circuit.
Under this physical pressure, connections become intermittent. The phone experiences brief power interruptions as the battery connector loses contact — and registers each interruption as a restart event. Unlike voltage-drop restarts (which happen under load), swelling-related restarts can happen at any battery level, including when the phone is fully charged and sitting idle.
Check for swelling now if your phone is experiencing random restarts: place the phone face-down on a flat, hard surface. If it rocks or wobbles, the battery is pushing the back panel up. Look at the screen-to-frame joint — any separation between the screen glass and the metal frame indicates the battery is pushing the screen away from the chassis from inside. If either sign is present, bring it in for urgent battery replacement — a swollen battery is a fire risk regardless of whether the restarts are your main concern.
🔴 Swollen Battery + Random Restarts = Urgent Same-Day Repair
Do not continue charging a phone that shows signs of swelling and random restarts. The two symptoms together confirm the battery cell has failed and is generating gas. Stop charging. Do not compress or bend the phone. Bring it to Mobile Connect Brisbane at Underwood Marketplace or Sunnybank Hills Shopping Town immediately — same-day battery replacement is available for most iPhone and Android models from $69.
Cause 3: Overheating Triggering Thermal Shutdown
All smartphones have thermal protection systems that shut down or restart the phone when internal temperature exceeds a safe threshold — typically 45–50°C internally. In Brisbane’s subtropical climate, this threshold is meaningfully easier to reach than in cooler cities.
A phone that restarts consistently during gaming, video streaming, or navigation in summer — particularly outdoors or in a hot car — may be experiencing a thermal shutdown rather than a software crash or battery fault. The distinction is the environmental context: thermal shutdowns are reproducible by recreating the hot, high-load scenario.
If thermal shutdown is the cause, the immediate fix is environmental — move to an air-conditioned environment, remove the phone case, and reduce processor load. But thermal shutdown restarts can also indicate a hardware thermal issue: accumulated dust blocking internal heat dissipation pathways, a failed thermal pad on the processor, or a battery with high internal resistance generating excess heat under load. If the restarts occur in cool environments under moderate load, an overheating assessment is warranted.
Cause 4: Loose Internal Connector or Motherboard Fault
A phone that was dropped — even without visible external damage — can develop a partially disconnected internal connector. The battery connector, the board-to-board connectors, and the antenna connections are all press-fit connections that can loosen under impact. A loose battery connector creates intermittent power events identical to a failing battery, but without the battery health degradation pattern.
The tell for a connector fault versus a battery fault: a connector fault typically begins immediately after a specific drop event. Battery degradation develops gradually over months. If your phone started restarting after a recent drop — even a minor one that didn’t crack the screen — a loose connector is a strong suspect. This requires opening the phone to inspect and reseat — a straightforward repair at Mobile Connect Brisbane but not one that can be done safely at home without the right tools.
Phone started restarting after a drop? That’s a loose connector.

Type 3: Boot Loops — Why Factory Reset Is Sometimes the Wrong First Step
A boot loop is when the phone restarts repeatedly and cannot complete the boot process to reach the home screen. It’s the most disruptive restart type and the one most likely to be mishandled — specifically by attempting a factory reset before understanding the underlying cause.
Software Boot Loops vs Hardware Boot Loops
💡 Software Boot Loop
Caused by a corrupted OS update, a system app conflict that prevents the boot sequence from completing, or a critically full storage that blocks essential boot processes. The phone has power — it attempts to boot, gets through part of the startup sequence, then crashes and restarts. You may see the manufacturer logo, the Android robot, or a partial loading animation before the loop restarts. A factory reset from recovery mode can fix a software boot loop — but only if the underlying hardware is sound.
🔴 Hardware Boot Loop
Caused by a battery that cannot sustain enough voltage to power the phone through the full boot sequence, a failed charging IC, or a motherboard fault. The phone may get partway through startup and restart when power demand exceeds what the failing battery can deliver at that moment. A factory reset does absolutely nothing for a hardware boot loop — it only affects software, not the battery or charging circuit causing the restart. Performing a factory reset on a hardware boot loop causes data loss with no benefit.
How to Distinguish a Software Boot Loop from a Hardware Boot Loop
The most reliable test is the charger test. Plug the phone into the original charger or a known-good wall adapter and observe the boot loop behaviour. If the boot loop slows significantly or the phone successfully completes a boot when plugged in versus on battery alone — the fault is hardware (battery can’t sustain boot power on its own). If the boot loop continues at the same rate whether plugged in or not — the fault is more likely software (power is sufficient but the OS is crashing).
A second test: on Android, attempt to enter recovery mode. The key combination varies by brand — typically Power + Volume Up held simultaneously during startup. If recovery mode is accessible (you can navigate the menu), the hardware is fundamentally sound and the boot loop is software-caused. If the phone crashes before reaching recovery mode, hardware is more likely the issue.
💡 The Rule: Diagnose Before Resetting
A factory reset should never be the first response to a boot loop — it should be the last software attempt after hardware has been ruled out. At Mobile Connect Brisbane, every boot loop diagnosis identifies whether the cause is software or hardware before recommending any data-destructive step. We’ve restored phones from boot loops caused by failed batteries without touching the data. Don’t let another shop talk you into a factory reset until the cause has been identified.
What to Do if Your Phone Is in a Boot Loop Right Now
Plug in the charger and observe
Connect the original charger and leave the phone on charge for 20 minutes without pressing any buttons. If the boot loop slows or the phone reaches the home screen when plugged in, the battery is failing — bring it in for battery replacement. If the loop continues unchanged, move to step 2.
Attempt to enter safe mode (Android)
Safe mode boots Android with only system apps — no third-party apps. On most Android phones: hold the Power button, then long-press the “Power Off” option until a “Safe Mode” prompt appears. If the phone boots successfully in safe mode but loops in normal mode, the boot loop is caused by a third-party app. Uninstall recently installed apps one by one from safe mode until the problem is resolved.
Attempt recovery mode (Android only)
If safe mode doesn’t work, try recovery mode (Power + Volume Up on most Android phones during startup). In recovery mode you can clear the system cache partition without a full factory reset — this resolves many update-related boot loops without touching personal data. Try “Wipe Cache Partition” before “Factory Reset.”
iPhone boot loop — force restart first
On iPhone 8 and later: quickly press and release Volume Up, quickly press and release Volume Down, then hold the Side button until the Apple logo appears. This force restart clears some transient software states and resolves boot loops caused by minor OS crashes. If the phone returns to the boot loop after the force restart, the fault is more persistent and requires professional diagnosis.
iPhone — connect to a Mac or PC and restore via Finder or iTunes
Connect the iPhone to a computer with a cable, open Finder (Mac) or iTunes (Windows), and put the iPhone into Recovery Mode (same button sequence as force restart but hold until the “Connect to Finder” screen appears). Finder will offer to Update (reinstall iOS without erasing data) or Restore (factory reset). Try Update first — it reinstalls iOS without touching your data and resolves most software boot loops.
Still in a boot loop after all of the above — bring it in
A boot loop that survives all of the above steps is either a hardware fault (battery, charging IC, motherboard) or a deep OS corruption that requires professional-level firmware tools. Bring it to Mobile Connect Brisbane at Underwood Marketplace or Sunnybank Hills Shopping Town — free diagnosis identifies the cause before any data-destructive step is recommended.
Brand-Specific Restart Causes — What We See Most at Mobile Connect Brisbane
iPhone — most common restart cause
Battery health degradation below 85% causing voltage-drop restarts under load. Check Settings → Battery → Battery Health. The second most common iPhone restart cause is a failed iOS update — connect to a Mac or PC and try the “Update” option in Finder before “Restore.” iPhone battery replacement from $69 at Mobile Connect Brisbane.
Samsung Galaxy — most common restart cause
Auto Restart scheduled feature accidentally enabled (Settings → Device Care → Auto Optimisation). Second cause: One UI memory management killing system processes aggressively on older models. Third: battery voltage failure on Galaxy S20 and A-series models 3+ years old. Check Samsung Members → Battery diagnostics. Samsung repair available at both Brisbane stores.
OPPO / OnePlus — most common restart cause
ColorOS battery optimisation killing system processes so aggressively it triggers a restart rather than a graceful app termination. Check Settings → Battery → Battery Optimisation and set critical apps to No Restrictions. Second cause: OPPO’s aggressive memory management under thermal throttling in Brisbane’s heat. OPPO repair available at Mobile Connect Brisbane.
Vivo — most common restart cause
FunTouch OS / OriginOS scheduled power-on/off feature enabled inadvertently (Settings → Battery → Scheduled Switch). Second cause: Vivo’s background app kill policy preventing system services from maintaining state, triggering system-level restart. Check Settings → Apps → Permissions for any aggressive battery restriction on system apps. Vivo repair at Underwood and Sunnybank Hills.
Xiaomi / Redmi — most common restart cause
MIUI/HyperOS’s scheduled on/off feature or ultra-battery-saver mode causing system restarts. Check Settings → Battery → Scheduled On/Off and Settings → Battery → Ultra Battery Saver. Second cause: MIUI system app updates pushed via the MIUI App Store that introduce bugs between major Android version releases — check Mi App Store for pending system app updates separately from the Android update check. Xiaomi repair at both Brisbane stores.
Google Pixel — most common restart cause
Monthly Android security updates on Pixel phones are more frequent than other brands — update-introduced bugs causing restarts resolve within 1–2 weeks with the next patch. Second cause: Google’s Adaptive Battery learning aggressively restricting background processes on apps it deems low-priority, occasionally triggering a system-level restart when the restricted app is a dependency for other processes. Google Pixel repair available at Mobile Connect Brisbane.

Frequently Asked Questions
Why does my phone keep restarting by itself?
Automatic phone restarts have three categories. Random unpredictable restarts are most commonly caused by a failing battery (voltage dropping under load), a rogue app crashing the OS, or a loose internal connector after a drop. Scheduled restarts at the same time every day are usually a deliberate feature enabled in settings — not a fault. Boot loops where the phone can’t reach the home screen are caused by software corruption or hardware failure.
Work through the diagnosis flowchart in this guide to identify which category applies to your phone before taking any action.
Can a bad battery cause my phone to restart?
Yes — battery failure is the most common hardware cause of random phone restarts. A degraded battery with high internal resistance drops voltage suddenly under load, causing the phone’s power management system to register a power failure and trigger a restart. This typically happens at low battery percentages (20–35%) or during demanding tasks, and the phone often restarts less frequently when plugged in.
A swollen battery also causes restarts by creating pressure on internal connectors, producing intermittent power events. Battery replacement at Mobile Connect Brisbane starts from $69 and is completed same day for most models.
My phone restarts at the same time every day — what is causing it?
A restart that happens at roughly the same time every day is almost certainly a scheduled restart feature enabled in settings, not a hardware or software fault. Samsung: Settings → Device Care → Auto Optimisation. OPPO/OnePlus: Settings → Additional Settings → Scheduled Power On/Off. Vivo: Settings → Battery → Scheduled Switch. Xiaomi: Settings → Battery → Scheduled On/Off. Disable the scheduled restart and the “fault” disappears immediately.
Should I factory reset my phone if it keeps restarting?
Not until you’ve confirmed the restart is caused by software rather than hardware. A factory reset fixes software-caused restarts (app conflicts, corrupted OS) but does nothing for hardware-caused restarts (failing battery, loose connector) — and causes unnecessary data loss in the process.
Determine the cause first: if the phone restarts during heavy use or at low battery, the cause is likely hardware. If it started after installing an app or updating the OS, software is more likely. When in doubt, a free diagnosis at Mobile Connect Brisbane identifies the cause before any data-destructive step is recommended.
What is a boot loop and how do I fix it?
A boot loop is when the phone restarts repeatedly and cannot reach the home screen. Software boot loops (caused by corrupted OS updates or system app conflicts) can often be resolved by entering safe mode, clearing the cache partition from recovery mode, or reinstalling the OS via Finder (iPhone) or recovery mode (Android) — without a full factory reset.
Hardware boot loops (caused by a battery too weak to sustain the boot power draw) require hardware repair — battery replacement in most cases. A factory reset has no effect on a hardware boot loop. If you’re unsure which type you have, bring it to Mobile Connect Brisbane for a free diagnosis before attempting any data-destructive action.
How much does it cost to fix a phone that keeps restarting in Brisbane?
