How Long Do Business Phones Last? When to Upgrade and When to Hold On

Last updated: April 2026

You bought those company phones two years ago. Maybe three. They were fast when they arrived. The batteries lasted all day. Everything worked.

Now? Someone's phone dies before lunch. Another keeps crashing mid-call with a client. The camera takes so long to open that by the time it is ready, whatever you needed to photograph has moved on.

So the question lands on your desk: do we need new phones? Or are we being dramatic?

The answer depends on what you bought, when you bought it, and what you need the phones to do. This guide breaks down exactly how long business phones actually last, when it makes sense to upgrade, when you should hold on, and how to get the best deal when the time comes.

How Long Do Smartphones Actually Last?

The short answer: 3 to 5 years for most phones. But the real answer depends on the manufacturer.

iPhone Lifespan

Apple supports its iPhones with software updates for 6 to 7 years from release. The iPhone 15 Pro, released in September 2023, will likely receive iOS updates until 2029 or 2030. Even the iPhone 12 from 2020 is still receiving security patches in 2026.

This makes iPhones the longest-lasting smartphones on the market from a software perspective. The hardware is built to match. Battery health typically remains above 80% for 2 to 3 years of normal use, and Apple's processors are powerful enough that a 4-year-old iPhone still runs current apps without noticeable lag.

For business use, you can realistically expect 5 to 6 years from a mid-range or higher iPhone before it becomes a productivity problem.

Android Lifespan

Android is more complicated because it depends on the manufacturer.

• Samsung flagship phones (Galaxy S series, Z Fold/Flip): Samsung now promises 4 OS updates and 5 years of security patches. The Galaxy S24 and newer get 7 years of updates, matching Apple. Older models like the S22 will stop receiving updates sooner.
• Samsung mid-range (Galaxy A series): Typically 3 OS updates and 4 years of security patches. Still decent, but you will hit end-of-life sooner.
• Google Pixel: Google offers 5 years of OS and security updates for Pixel 6 onwards, and 7 years for Pixel 8 and newer. Excellent software support, though the mid-range hardware means performance may lag before updates stop.
• Budget Android phones (under £200): Expect 2 to 3 years of updates at most. Some budget manufacturers stop security patches after 18 months. For business use, this is a genuine security risk.

Signs It Is Time to Upgrade

A phone does not just stop working one day. It degrades gradually. Here are the warning signs that a business phone has reached the end of its useful life.

The Battery Dies Before the Working Day Ends

This is the most common complaint we hear. If your team's phones are regularly hitting 10% by 2pm, you have a problem. A field sales rep whose phone dies at 3pm cannot take client calls, access the CRM, or navigate to meetings. That is not an inconvenience. That is lost revenue.

Battery replacement is an option. Apple charges around £89 for an out-of-warranty battery replacement, and third-party repairs are cheaper. But if the phone is already 3 to 4 years old, you are putting a new battery in a phone that will stop receiving security updates within a year. It is a short-term fix.

Security Updates Have Stopped

This is the one people ignore, and it is the most important. Once a phone stops receiving security patches, every known vulnerability from that point forward is permanently unpatched. Your business data, client information, emails, and everything on that phone is at risk.

For businesses handling customer data, this is not optional. Under UK GDPR, you have a legal obligation to take appropriate technical measures to protect personal data. Running phones past their security update window is a data protection risk that could land you in trouble with the ICO.

Running phones that no longer receive security updates? That is a GDPR risk your business does not need. Talk to us about upgrading on a deal that works for your budget. Get a free quote.

Apps Keep Crashing

When apps start crashing regularly, it usually means the phone's processor and RAM cannot keep up with current software requirements. App developers optimise for newer hardware, and older phones gradually get left behind.

For business-critical apps like Microsoft Teams, Outlook, Salesforce, or Xero, crashes are not just annoying. They interrupt meetings, lose unsent emails, and break workflows.

Performance Has Slowed to a Crawl

If it takes 5 seconds to open the camera, 10 seconds to load an email, and the keyboard lags behind your typing, the phone is costing you time every single day. Multiply that across a team of 10, and you are losing hours of productivity per week.

The Screen Is Cracked and Repair Costs More Than It Is Worth

A cracked screen on a 4-year-old phone is the universe telling you to move on. Screen repairs for flagship phones cost £200 to £350. At that price, you are halfway to a new mid-range phone on a business contract, and you get a fresh battery, current software support, and a 24-month warranty included.

iPhone vs Android: Which Lasts Longer for Business?

The honest answer: iPhones last longer on average, primarily because of Apple's industry-leading software support.

That said, the gap is closing. Samsung's commitment to 7 years of updates on the Galaxy S24 and newer puts it on par with Apple for the first time. If your team prefers Android, a Samsung flagship is now a genuinely long-term investment.

The Security Risk of Running Old Phones

This deserves its own section because it is the factor most businesses underestimate.

When a phone stops receiving security updates, it becomes a permanent vulnerability. New exploits are discovered every month. Without patches, each one is an open door into your business data.

Consider what lives on a typical business phone:

• Company email (including client communications and contracts)
• CRM access with customer contact details
• Cloud storage apps with business documents
• Banking and payment apps
• WhatsApp or Teams messages containing sensitive discussions
• Saved WiFi passwords for your office network

If that phone is compromised because it is running unpatched software, you are looking at a potential data breach. Under UK GDPR, that means mandatory ICO notification if personal data is affected, potential fines of up to 4% of annual turnover, and the reputational damage of having to tell your clients their data was exposed because you did not replace a phone.

The cost of a new business phone contract is typically £25 to £50 per month. The cost of a data breach starts at thousands and goes up from there. The maths is not complicated.

When SIM-Only Makes More Sense Than a New Handset

Not every phone that is getting old needs replacing. If the hardware is still solid, the battery lasts a full day, and the phone is still receiving security updates, there is no reason to buy a new handset.

In that case, a SIM-only deal saves you serious money.

A typical business handset contract costs £35 to £60 per month because you are paying off the phone over 24 or 36 months. A SIM-only deal with the same data and minutes costs £8 to £20 per month. That is a saving of £20 to £40 per line per month, or £240 to £480 per line per year.

For a business with 10 lines, switching to SIM-only where possible could save £2,400 to £4,800 per year. That is real money.

The sweet spot for SIM-only is when your phones are 2 to 3 years old, still performing well, and still receiving updates. You have another 1 to 2 years of life in them. Go SIM-only for 12 months, save the cash, and upgrade when the phones actually need replacing.

24-Month vs 36-Month Contracts: Matching Contract Length to Phone Lifespan

This is where a lot of businesses get caught out.

A 24-month contract made sense when phones lasted 2 to 3 years. Your contract ended around the same time the phone needed replacing. Clean and simple.

Now networks are pushing 36-month contracts because they lock you in longer and the monthly payment looks lower. And for iPhones and Samsung flagships, 36 months is actually reasonable. Those phones will still be performing well and receiving updates at the 3-year mark.

But for mid-range and budget phones, a 36-month contract is a trap. You will be paying for 3 years on a phone that is effectively obsolete after 2. The last 12 months of that contract, you are stuck with a slow, insecure phone and you cannot upgrade without paying an early termination fee.

Our recommendation:

• iPhones and Samsung S/Z series: 36-month contracts are fine. The phones will last.
• Samsung A series and mid-range Android: Stick to 24 months. You will want to upgrade before a 36-month term ends.
• Budget phones: Never go beyond 24 months. Consider buying outright and going SIM-only.

The Tax Angle: Company Phones Are a Tax-Free Benefit

One thing that makes upgrading easier to justify: if your company provides a mobile phone to an employee, it is a tax-free benefit in kind under ITEPA 2003, Section 319. One phone per employee, regardless of cost, is exempt from income tax and National Insurance.

That means the full cost of the contract, handset and airtime, is a deductible business expense. There is no benefit-in-kind charge for the employee either, provided the phone is company-owned and one per person.

For sole traders and partnerships, you can claim the business-use proportion of your phone costs against tax. If you use the phone 70% for business, you claim 70% of the cost.

This makes the real cost of upgrading lower than the sticker price suggests. A £45/month contract costs your business less than £45/month after tax relief.

Frequently Asked Questions

How long does an iPhone last for business use?

An iPhone typically lasts 5 to 6 years for business use. Apple provides software updates for 6 to 7 years from release, and the hardware is built to match. Battery health usually remains above 80% for the first 2 to 3 years, and performance remains strong for 4 to 5 years.

How long does a Samsung phone last?

Samsung flagship phones (Galaxy S series, Z Fold/Flip) last 4 to 5 years. Newer models like the S24 onwards receive 7 years of updates, matching Apple. Mid-range Samsung A series phones typically last 3 years before performance and update support become an issue.

Is it a security risk to keep using old business phones?

Yes. Once a phone stops receiving security updates, every new vulnerability is permanently unpatched. For businesses handling customer data, this creates a UK GDPR compliance risk. The ICO expects businesses to take appropriate technical measures to protect personal data, and running unpatched devices does not meet that standard.

Should I choose a 24-month or 36-month business mobile contract?

For iPhones and Samsung flagships, 36-month contracts are reasonable as these phones will still perform well and receive updates. For mid-range phones, stick to 24 months. For budget phones, 24 months maximum, or consider buying outright and going SIM-only.
