Most Common Causes of Mobile Phone Damage

Unfortunately, that also makes it vulnerable to damage.

Whether it's a cracked screen after an accidental drop or a phone that's lost or stolen, repairing or replacing a smartphone can be expensive—particularly as many flagship devices now cost £1,000 or more.

Understanding the most common causes of phone damage can help you reduce the risks and keep your device protected.

Quick Answer

The most common causes of mobile phone damage and device-related issues include:

• Dropping your phone onto a hard surface, resulting in a cracked screen
• Phone theft, particularly in busy public places
• Accidentally leaving a phone behind on public transport or in a taxi
• Liquid damage caused by spills, rain or accidental immersion in water
• Battery deterioration resulting from age, repeated charging cycles or exposure to extreme temperatures
• Charging port damage caused by debris, wear and tear or use of unsuitable charging accessories
• Back glass damage caused by drops, impacts or pressure on the device
• Camera damage caused by scratches, impact damage or exposure to dirt and moisture
• Mechanical or electrical breakdown due to internal component failure

At insurance2go, accidental damage, theft and loss are among the most common reasons customers seek protection for their devices.

Why Phone Damage Is So Common

Unlike many other possessions, smartphones are constantly being handled, carried and used throughout the day.

A typical phone might be:

• Taken on public transport
• Used while walking
• Stored in bags and pockets
• Carried on holiday
• Used during work meetings
• Kept beside the bed at night

The more time a device spends in use, the greater the chance of accidental damage occurring.

1. Accidental Drops

Dropping a phone is one of the most common causes of damage.

This can result in:

• Cracked screens
• Scratched displays
• Damaged camera lenses
• Bent frames
• Internal component damage

Even a drop from pocket height can cause significant damage, particularly on modern smartphones with glass displays and backs.

Insurance2go Expert Tip

Even if your phone looks undamaged after a fall, check:

• Touchscreen responsiveness
• Camera quality
• Speakers
• Microphone functionality
• Face ID or fingerprint recognition

Some types of internal damage aren't immediately visible.

2. Cracked Screens

Screen damage is one of the most frequent reasons people seek phone repairs.

Common causes include:

• Dropping the phone
• Knocking it off a table
• Sitting on it accidentally
• Carrying it in crowded bags or pockets

As smartphones become larger and more expensive, screen repairs can cost hundreds of pounds.

3. Liquid Damage

Although many modern phones offer some water resistance, liquid damage remains a major risk.

Common incidents include:

• Dropping a phone in water
• Spilling drinks
• Using a phone in heavy rain
• Exposure to moisture or steam

Liquid can damage internal components and may lead to expensive repairs or permanent device failure.

Insurance2go Expert Tip

If your phone gets wet:

• Turn it off immediately
• Remove any accessories
• Avoid charging it
• Seek professional advice as soon as possible

Acting quickly may help minimise damage.

4. Theft

Mobile phones are valuable and highly portable, making them a target for thieves.

Phone theft can occur:

• On public transport
• In busy city centres
• In restaurants and cafés
• While travelling abroad

Beyond losing the device itself, theft can expose personal data, banking apps and online accounts if action isn't taken quickly.

5. Loss

Many people lose their phones without them being stolen.

Common examples include:

• Leaving a phone on public transport
• Forgetting it in a taxi
• Misplacing it while travelling
• Leaving it in a restaurant or shop

Replacing a lost phone can be just as costly as replacing a stolen one.

6. Battery Problems

Battery issues can develop over time due to normal wear and tear, repeated charging cycles or exposure to extreme temperatures. For example, regularly leaving a phone in a hot car can accelerate battery degradation.

Common signs include:

• Fast battery drain
• Unexpected shutdowns
• Slow charging
• Overheating

While battery wear is a normal part of ownership, it is one of the most common reasons older phones require repair.

7. Charging Port Damage

Charging ports experience daily wear and tear.

Problems can arise from:

• Dirt and debris build-up
• Repeated plugging and unplugging
• Using damaged or unsuitable charging cables
• Forcing a connector into the port incorrectly
• Accidental impact damage

8. Back Glass Damage

Many premium smartphones feature glass backs to support wireless charging.

Unfortunately, these surfaces can crack when:

• Dropped onto hard surfaces
• Knocked against furniture or other hard objects
• Subjected to pressure, such as sitting down with the phone in a back pocket

Where the damage affects the functionality or structural integrity of the device, repairs may be required.

9. Camera Damage

Smartphone cameras have become more advanced, but they can also be vulnerable to damage.

Common causes include:

• Dropping the device
• Scratching the camera lens
• Exposure to dirt and moisture
• Impact damage during travel

Camera repairs can be costly due to the complexity of modern camera systems.

10. Mechanical Breakdown

Not all phone damage is accidental. Electronic components can fail due to:

• Manufacturing defects
• Age-related wear
• Software issues
• Internal hardware faults

While less common than accidental damage, repairs can still be expensive depending on the issue.

Which Types of Phone Damage Are Most Expensive?

Not all repairs cost the same.

Typically, the most expensive phone repairs include:

• OLED screen replacements
• Back glass repairs
• Camera system replacement
• Water damage repair
• Motherboard repairs

For premium smartphones, repair costs can quickly run into hundreds of pounds.

This is one reason many people consider phone insurance, particularly for newer devices.

How Can You Reduce the Risk of Phone Damage?

A few simple precautions can help protect your device:

• Use a protective case
• Install a screen protector
• Keep your phone away from liquids
• Avoid leaving your phone unattended
• Enable device tracking features
• Store your phone securely while travelling
• Regularly back up important data

While no method can eliminate risk entirely, these steps can reduce the likelihood of damage.

The Reality Is That Phone Damage Can Happen to Anyone

Most people don't expect to drop, lose or damage their phone until it happens.

Whether it's a cracked screen after a simple slip, a phone left behind in a taxi or accidental liquid damage during a coffee spill, the cost of repairs can add up quickly.

Understanding the most common causes of mobile phone damage can help you reduce your risk, but accidents aren't always preventable. That's why many smartphone owners choose phone insurance for additional peace of mind.
