How Long Do iPhones Last? Lifespan Explained

How long do iPhones last? For most people, five to seven years of useful life, and often longer as a second phone. But that number hides three separate clocks: how long Apple keeps sending iOS updates, how long the battery stays healthy, and how long the phone keeps working on Pakistani networks. Each clock runs at a different speed.

For a buyer in Lahore, the question that matters is not how long a new iPhone lasts. It is how many good years are left in the phone you are about to buy. This guide explains each clock and how to use them when choosing a used model.

Apple supports iPhones for longer than most phone makers. A typical model gets five to seven years of major iOS updates, and then often a period of security fixes on its last version.

You can see the pattern in today's lineup. iOS 26, released in September 2025, supports the iPhone 11 and later, plus the iPhone SE (2nd generation) and later. The iPhone XS, XS Max and XR, all from 2018, stopped at iOS 18. The iPhone 11 launched in 2019, so it has received roughly six years of major updates so far.

Apple never announces in advance how long a model will be supported. Use history as a guide, not a promise. Our iPhones no longer supported guide covers what happens when your model drops off the list.

The phone does not switch off. Your apps keep working for a while, then some start to require a newer iOS and stop installing or updating. Banking apps tend to be among the first to raise their minimum version, and so do some wallets. Security fixes may continue for a while on the final version, but the risk rises over time.

The battery usually ages faster than the software. Apple says older iPhone batteries are designed to keep about 80 percent of their original capacity after 500 full charge cycles. For the iPhone 15 and later, Apple says the same 80 percent after 1,000 cycles.

The good news is that a battery is replaceable. A worn battery does not end a phone's life. It just adds a cost to the decision. Our iPhone battery health check guide explains how to read the numbers on a used phone.

This one is specific to Pakistan. A phone can be perfectly healthy and still become hard to use because of its registration status.

• PTA approved phones work on any local SIM for as long as the hardware lasts.
• Non-PTA phones may only work on a local SIM for a limited period, or only with Wi-Fi. Check the current rule on the PTA DIRBS website, because it changes.
• Patched phones are the riskiest. The patch may stop working after an iOS update, so owners often avoid updating. In practice, that means the phone's software life ends the day you buy it, and the security risk grows every month after.
• JV or factory unlocked (FU) phones also depend on registration. Ask about PTA status before anything else.

So a patched iPhone 14 can have a shorter useful life than a PTA approved iPhone 12. Our guide to PTA approved iPhone prices explains how status affects value.

Think about how long you plan to keep the phone, then work backwards.

1. Keeping it two years or less? An older model such as an iPhone 11 or 12 can work if it is cheap and the battery is good. Accept that the 11 is the oldest phone on the current iOS and is likely to be among the first dropped.
2. Keeping it three to four years? Aim for an iPhone 13 or newer. These are a few years younger in the support cycle and still feel quick for daily use.
3. Keeping it five years or more? Look at an iPhone 15 or newer. You get more remaining update years and the battery is rated for twice the cycles.
4. Buying for a parent or child? Remaining update years matter more than the camera, because they will not want to switch phones often.

Then adjust for condition. A newer phone with a weak battery and a third-party screen can be worse value than a slightly older one in clean, original condition. Ask the seller three things: battery health and cycle count, whether any part has been replaced, and the PTA status. Our used iPhone Lahore buyer's guide covers the full inspection.

Replacing too early wastes money, and so does pouring repairs into a phone that is near the end. A simple rule of thumb:

• Replace the battery, not the phone, if the phone is still on current iOS, runs your apps well and the only complaint is battery life.
• Replace the phone if it is already off the latest iOS, an app you depend on has stopped supporting it, or the repair bill approaches a large part of the cost of a newer used model.
• Replace the phone if storage is constantly full and you are always deleting photos. More storage on a newer model often fixes a daily annoyance.
• Hold on if it is working well and you are only tempted by a new launch. Prices on the previous models usually soften after Apple's September event.

• Keep it out of direct sun and hot cars, and take it out of a thick case while charging in summer.
• Turn on Optimised Battery Charging, or the 80 percent limit on iPhone 15 and later.
• Install iOS updates once the first fixes are out, so you keep security patches.
• Use a decent cable and charger. Cheap chargers can stress the charging port and the battery.
• Use a case and screen protector. A cracked screen often starts the chain of third-party repairs that hurts resale.

If you are weighing models by how many years they have left, browse the iPhone page, where listings show PTA status and battery information when available. Send MacVault the model you are considering on WhatsApp, and ask for today's price along with the battery health screenshot and any repair history.
