Physical damage to an iPhone can cause problems ranging from a button that intermittently stops responding to serious safety conditions such as a swollen lithium-ion battery, separated display, damaged charging connector or liquid-damaged internal components.
Unlike many software problems, hardware faults should not automatically be approached with resets, restores and iOS reinstalls. The first task is to determine whether the problem is caused by:
- a case or accessory,
- dirt or debris,
- an iOS configuration issue,
- temporary moisture,
- mechanical wear,
- impact damage,
- liquid ingress,
- internal connector damage,
- battery expansion,
- or failure of an electronic component.
Apple specifically warns that an iPhone or its battery can be damaged by drops, crushing, punctures and liquids. If significant device or battery damage is suspected, continued use can create overheating or injury risks.
This guide covers physical and hardware problems 670 through 691.
670. iPhone Power Button / Side Button Not Working
The Side button—commonly called the power button—is used for locking the iPhone, waking it, invoking Siri, Apple Pay functions, screenshots in combination with other buttons and emergency functions.
Symptoms
You may notice:
- Side button does nothing
- button works only when pressed hard
- button feels stuck
- button has lost its normal click
- intermittent response
- iPhone cannot easily be locked
- Siri or Apple Pay shortcut does not activate
First checks
Remove the case and test the button again.
Some tight or damaged cases prevent the Side button from moving through its full travel.
Restart the iPhone if possible.
Also inspect around the button for visible dirt or physical deformation.
Temporary workaround
Depending on your iOS version, you can use:
Settings → Accessibility → Touch → AssistiveTouch
AssistiveTouch can provide on-screen access to several functions normally performed with hardware buttons.
When hardware repair is likely
Repair may be necessary when:
- button is physically stuck
- button has been pushed into the enclosure
- problem began immediately after a drop
- liquid entered near the button
- button works only at certain angles
- physical clicking mechanism is damaged
671. iPhone Volume Button Not Working
First remove the case and verify that it isn't obstructing the buttons.
Test both Volume Up and Volume Down.
Also test volume using Control Center.
If Control Center changes volume correctly but the physical buttons don't, the problem is more likely associated with the buttons or related hardware rather than the audio system itself.
Possible causes include:
- damaged button mechanism
- dirt around button
- damaged internal flex assembly
- impact damage
- liquid ingress
- enclosure deformation
If only one physical volume button has failed consistently, hardware inspection is recommended.
672. iPhone Action Button Not Working
On supported iPhone models, the Action button can be configured for different functions.
Check:
Settings → Action Button
Confirm that the desired action is assigned.
Test another Action button function.
For example, temporarily configure it for a simple function and retest.
If no assigned functions work, remove the case and check the physical button.
If the Action button stopped working immediately after impact, liquid exposure or repair, hardware service may be necessary.
673. iPhone Camera Control Not Working
Camera Control is available only on supported iPhone models.
If Camera Control doesn't respond correctly:
- Restart the iPhone.
- Remove any case or accessory that may interfere with the control.
- Verify Camera Control settings.
- Test it in Apple's Camera app.
- Install the latest compatible iOS update.
- Determine whether only gestures/press sensitivity or the entire control has stopped responding.
If the problem started after dropping the phone or replacing its enclosure/display, professional inspection may be required.
674. iPhone Mute Switch Not Working
On iPhones equipped with a Ring/Silent switch, repeatedly move the switch between positions.
Remove the case first.
If the switch moves but the iPhone doesn't recognize the state change, possible causes include:
- damaged switch
- internal flex failure
- contamination
- liquid damage
- previous repair damage
Do not force a jammed switch with a sharp object.
675. iPhone Home Button Not Working
This applies primarily to older iPhones equipped with a physical Home button.
Possible symptoms include:
- no response
- intermittent response
- Touch ID unavailable
- button feels abnormal
- Home function works but Touch ID doesn't
Restart the device and remove accessories that could obstruct the button.
A damaged Home button—particularly one associated with Touch ID—should be handled carefully because biometric hardware has security-related pairing considerations.
Use AssistiveTouch as a temporary alternative where available.
676. iPhone Vibration Not Working
First determine whether the problem is actually hardware.
Check the iPhone's sound and haptic settings.
Go to:
Settings → Sounds & Haptics
Verify relevant haptic options.
Test vibration from multiple functions.
If vibration fails everywhere despite correct settings, possible causes include:
- Taptic Engine malfunction
- loose internal connection
- physical impact
- liquid damage
- previous repair issue
677. iPhone Taptic Engine Not Working
The Taptic Engine generates precise haptic feedback.
Symptoms of failure can include:
- no vibration
- weak vibration
- rattling
- unusually loud vibration
- inconsistent haptic feedback
A strange mechanical rattling sound following a drop may indicate physical damage or a loose component.
Current Apple repair documentation includes dedicated troubleshooting and service procedures for Taptic Engine/haptic-feedback faults on supported models.
Persistent mechanical symptoms normally require internal inspection.
678. iPhone USB-C Port Loose
Newer USB-C iPhones can develop symptoms such as:
- cable feels unusually loose
- charging disconnects when cable moves
- computer connection repeatedly disconnects
- CarPlay disconnects
- cable doesn't fully seat
Before assuming the connector is broken, test another known-good USB-C cable.
Inspect the connector for visible debris.
Accumulated lint can prevent a connector from seating completely.
Important
Do not aggressively scrape the connector with needles, pins or metal objects.
Physical connector damage can require replacement of the USB-C connector assembly.
Apple's current parts-support documentation identifies the USB-C connector as a serviceable component on supported recent models.
679. iPhone Lightning Port Loose
A Lightning cable that doesn't stay securely connected can be caused by:
- lint inside connector
- damaged cable
- worn cable plug
- connector damage
- bent or damaged internal contacts
Try another genuine or appropriately certified cable.
If multiple cables behave identically, inspect the iPhone connector.
Never aggressively dig inside the Lightning port using metallic tools.
680. iPhone Charging Port Damaged
Common symptoms include:
- iPhone doesn't charge
- charging works only at an angle
- cable repeatedly connects/disconnects
- computer doesn't detect iPhone
- CarPlay fails
- visible physical damage
- cable no longer fits correctly
First distinguish among:
Cable problem → Charger problem → Dirt/debris → Moisture → Connector damage → Internal charging fault
Testing with another known-good cable and power adapter is an important diagnostic step.
If the connector is visibly damaged, professional repair is recommended.
681. iPhone Speaker Damaged
Speaker failure can appear as:
- distorted sound
- crackling
- very low volume
- intermittent sound
- no sound
- rattling at certain frequencies
Test several sources:
- ringtone
- music
- speakerphone
- videos
- system sounds
If only one app is affected, the problem may not be hardware.
Water can also temporarily affect speaker performance. Apple notes that water in the speaker or microphone area can degrade audio performance until it evaporates.
682. iPhone Microphone Damaged
An iPhone contains multiple microphones, so microphone troubleshooting requires testing different functions.
Test:
- Voice Memos
- normal phone calls
- speakerphone
- front-camera video
- rear-camera video
If one recording mode fails while others work correctly, a particular microphone or associated component may be affected.
Remove any case or screen protector obstructing microphone openings.
Persistent distortion, extremely low audio or complete failure after impact/liquid exposure may require repair.
683. iPhone Camera Lens Cracked
A cracked external camera lens can cause:
- blurry photographs
- glare
- light streaks
- inability to focus correctly
- dust entering the camera area
- increased vulnerability to moisture
Do not continue intentionally exposing a damaged iPhone to water.
Even if the camera still works, cracked protective glass compromises the physical integrity of the device.
Camera repairs should ideally use appropriate parts and procedures. Apple notes that non-genuine camera components may cause compatibility or performance problems.
684. iPhone Camera Stabilization Damaged
Modern iPhone camera systems can contain sophisticated autofocus and optical stabilization mechanisms.
Possible symptoms include:
- camera image shaking
- camera continuously vibrating
- clicking or buzzing
- inability to focus
- blurry photos
- unstable video
- camera malfunction after a hard drop
Test all available rear-camera lenses separately.
If only one camera exhibits violent shaking or cannot focus, that camera module may be damaged.
Persistent mechanical camera failure generally requires service rather than an iOS reset.
685. iPhone Back Glass Cracked
Cracked back glass isn't merely cosmetic when damage is severe.
Potential consequences include:
- sharp glass edges
- moisture ingress
- dust ingress
- weakened enclosure
- wireless charging complications after severe damage
- exposure of internal components in extreme cases
Apple advises against using an iPhone with cracked glass because of injury risk.
Have severely damaged back glass professionally repaired.
686. iPhone Screen Separated From Body
Treat this symptom seriously.
A display lifting away from the enclosure can result from:
- failed display adhesive,
- impact/enclosure deformation,
- previous improper repair,
- or an expanding battery underneath the screen.
If the screen appears to be pushed outward from inside the phone, battery swelling should be considered.
Do not
- press the screen forcefully back into place
- clamp the phone together
- puncture the enclosure
- continue charging a suspected swollen battery
If battery expansion is possible, discontinue normal use and arrange professional service.
687. iPhone Battery Swollen
A swollen lithium-ion battery is a safety issue, not a normal troubleshooting condition.
Signs may include:
- screen lifting
- gap between display and enclosure
- back or enclosure deformation
- unusual pressure marks on display
- rapid battery deterioration
- abnormal heating
Apple warns that battery service should be performed by trained technicians because battery damage can lead to overheating, fire or injury.
What to do
Stop using the iPhone if battery swelling is suspected.
Do not:
- puncture the battery
- bend the device
- press the display back down
- attempt to flatten the battery
- continue charging it unnecessarily
- expose it to heat
Arrange professional battery service.

688. Water-Damaged iPhone
An important misconception is:
Water-resistant does not mean waterproof.
Many iPhone models have IP67 or IP68 water-resistance ratings under controlled laboratory conditions, but Apple explicitly states that splash, water and dust resistance aren't permanent and can decrease with normal wear.
Resistance can also be affected by:
- drops
- enclosure damage
- cracked glass
- previous repairs
- deteriorated seals
- aging
- physical deformation
Therefore, an IP68 rating should never be interpreted as a guarantee that liquid cannot damage the phone.
689. iPhone Dropped in Water – What Should You Do?
If an iPhone gets wet:
- Remove it from the liquid.
- Disconnect cables and accessories.
- Wipe the exterior with a soft, lint-free cloth.
- Hold the Lightning/USB-C connector downward.
- Gently tap the phone against your hand to encourage excess liquid to leave the connector.
- Place it somewhere dry with airflow.
- Allow sufficient drying time before wired charging.
Apple specifically advises against using an external heat source or inserting objects such as cotton buds or paper towels into the connector. Cool airflow toward the connector may help drying.
Should You Put a Wet iPhone in Rice?
No.
Rice is not a recommended professional drying technique and can introduce particles into openings.
Avoid:
- hair dryers
- ovens
- heaters
- compressed air
- inserting paper/tissue into connector
- inserting cotton buds
- repeatedly plugging in a cable to "test" it
Allow evaporation and airflow to do the work.
690. iPhone Won't Turn On After Water Damage
This situation requires particular caution.
Possible causes include:
- deeply discharged battery
- liquid inside connector
- short circuit
- battery damage
- charging circuitry failure
- display failure
- corrosion
- logic-board damage
Do not repeatedly connect and disconnect chargers while the device may still contain moisture.
Once the iPhone has had adequate drying time, try the appropriate force-restart procedure for the model.
If the phone remains completely dead after liquid exposure, professional inspection is preferable to repeated charging attempts.
Important data consideration
If important information isn't backed up, tell the repair provider that data recovery is a priority before authorizing any replacement or destructive repair procedure.
691. Liquid Detection Warning Won't Disappear
Supported iPhones can detect liquid in the Lightning or USB-C connector and display a warning when a cable or accessory is connected.
This protection exists because charging while moisture is present can damage the connector or device.
Apple recommends disconnecting cables and allowing the device to dry completely before wired charging.
If the warning remains
Disconnect the cable.
Place the iPhone in a dry area with airflow.
Keep the connector facing downward where practical.
Wait and try again later.
Do not insert:
- tissue
- cotton buds
- metal objects
- cleaning tools
into the connector to accelerate drying.
If the warning continues after the device has had ample time to dry, try another known-good cable/accessory.
If the alert occurs repeatedly with different cables when the iPhone is definitely dry, the connector may require inspection.
Hardware or Software? Quick Diagnostic Guide
| Symptom | More Likely Cause |
|---|---|
| Button works after removing case | Case interference |
| Button physically stuck | Hardware |
| Volume works from Control Center but not buttons | Button hardware likely |
| Camera shakes after hard drop | Camera hardware/stabilization |
| Cable works only at an angle | Debris/connector/cable |
| Several cables fall out | Connector debris or physical wear |
| Speaker muffled immediately after water | Residual moisture possible |
| Screen lifting from enclosure | Adhesive, impact or swollen battery |
| Screen pushed outward without major impact | Swollen battery must be considered |
| Liquid alert immediately after exposure | Moisture detection |
| Liquid alert repeatedly appears while dry | Cable/connector inspection needed |
| Phone dead after immersion | Potential internal liquid damage |
Water Damage: What NOT to Do
Avoid common actions that can make the situation worse:
- Do not intentionally submerge the phone again to test water resistance.
- Do not use a hair dryer.
- Do not place the phone in an oven.
- Do not apply excessive heat.
- Do not insert cotton buds into the connector.
- Do not aggressively scrape charging contacts.
- Do not immediately connect a wired charger to a wet connector.
- Do not assume an IP rating guarantees protection from water damage.
Apple recommends allowing at least 5 hours before wired charging or connecting an accessory after liquid exposure, and the phone should be completely dry before doing so.
When Should You Stop Using the iPhone Immediately?
Discontinue normal use and seek professional assistance when you observe:
- swollen battery
- screen being pushed outward
- excessive heat after physical damage
- smoke or unusual smell
- severely cracked glass exposing internal components
- badly deformed enclosure
- serious liquid exposure followed by overheating
- damaged battery after a drop
- exposed internal components
Battery damage deserves particular caution because lithium-ion battery failure can result in overheating or fire.
Should You Repair an iPhone Yourself?
Simple external troubleshooting—removing a case, checking settings, trying another cable or carefully inspecting the connector—is reasonable for most users.
Internal repair is different.
Modern iPhones contain tightly integrated components, adhesives, batteries and calibrated parts. Apple states that repairs performed by untrained people or using non-genuine components can affect functionality and safety.
Some recent models support Apple's Self Service Repair program in eligible countries/regions, but it is intended for people experienced with electronic-device repair. Availability also varies by model and location.
For serious physical damage, professional repair is generally the safer option.
Apple iPhone Repair and Service
Check Parts and Service History After Repair
After certain iPhone repairs, supported models can show information about replaced components.
Depending on the iPhone model and iOS version, check:
Settings → General → About → Parts and Service History
The available information depends on the model and component. Apple currently provides service-history information for components such as batteries, displays, cameras and other supported parts on eligible models.
This can be useful after repairing physical damage.
