The iPhone 15 Pro Max launched in September 2023. If you bought one near launch, you have been using it for close to three years.
That is long enough for the initial excitement to wear off and for real world durability to show itself. The battery has had a thousand charge cycles. The titanium frame has collected scratches. The screen has survived (or not survived) dozens of near misses.
Most tech reviews focus on the first week of ownership. This one looks at the iPhone 15 Pro Max from the other end: how it holds up after years of daily use, what commonly goes wrong, and whether it is worth repairing or replacing in 2026.
What Still Holds Up Well
Performance: The A17 Pro chip has not slowed down. It handles current apps, multitasking, and gaming without any noticeable lag. Even with the iPhone 17 series now available, the 15 Pro Max does not feel slow in daily use. Apple’s chips age better than most because iOS is optimised specifically for them.
Camera: The 48 MP main camera and 5x optical zoom telephoto still produce excellent photos. Computational photography updates through iOS have actually improved image quality since launch. The camera on a 2026 iPhone 15 Pro Max takes better photos than it did in 2023, which is unusual for any piece of hardware.
Software support: Apple typically provides six to seven years of iOS updates. The iPhone 15 Pro Max will continue receiving updates until at least 2029. That means three to four more years of security patches and new features. In terms of software life, this phone is not even halfway done.
Build quality: The titanium frame has held up better than the stainless steel on older Pro models. It is lighter, more scratch resistant on the edges, and less prone to showing fingerprints. The Ceramic Shield front glass is tough, though not unbreakable.
What Shows Its Age
Battery life: This is the most common complaint from long term 15 Pro Max owners. After two to three years of daily charging, the battery capacity drops noticeably. A phone that used to last well into the evening might now need a top up by mid afternoon.
Check your battery health: go to Settings, then Battery, then Battery Health and Charging. If Maximum Capacity is at or below 80%, a replacement will make a significant difference. The 15 Pro Max has a 4,441 mAh battery, which is generous by iPhone standards, so even at 80% capacity it should still get through a moderate day. If it does not, the battery is the likely culprit.
Charging speed: The iPhone 15 Pro Max tops out at 27W wired charging. In 2023, that was competitive. In 2026, Samsung and OnePlus offer 45W to 100W charging. This is not something that can be fixed with a repair, but it is worth knowing if you are comparing it to newer phones.
Weight: At 221 grams, it is heavier than the iPhone 17 Pro Max (which switched to aluminium). If you have used a lighter phone recently, the 15 Pro Max feels noticeably dense. Some people like that. Others do not.
USB C port wear: The iPhone 15 Pro Max was Apple’s first Pro phone with USB C. After three years of daily plugging and unplugging, some users find the port gets loose or intermittent. Lint compaction is the usual cause. A clean with a wooden toothpick often fixes it. If not, the port can be replaced.
Common iPhone 15 Pro Max Repairs We See
At Phone Clinic, the iPhone 15 Pro Max is one of the most common devices we repair. After nearly three years on the market, the typical repairs are predictable.
Battery replacement: The most requested repair for this model. After 800 to 1,000 charge cycles, the battery no longer holds its original capacity. A replacement restores the phone to how it felt when it was new. The work takes under an hour and your data stays on the phone.
Screen replacement: Cracked screens on the 15 Pro Max are common because of the phone’s size and weight. A 6.7 inch phone with a glass front is always one drop away from needing a new display. The OLED screen replacement includes the full display assembly.
Charging port repair: After years of use, the USB C port can develop connection issues. This is usually a straightforward replacement.
Back glass: The 15 Pro Max has a glass back for wireless charging. Cracks here are mostly cosmetic but can affect water resistance over time.

Should You Repair It or Replace It?
The iPhone 15 Pro Max still has three to four years of software updates ahead of it. The A17 Pro chip is still fast. The camera is still excellent. Unless you need features that only exist on the iPhone 17 series (Apple Intelligence requires 12 GB of RAM, which the 15 Pro Max does not have), this phone has a lot of useful life left.
Here is how the repair costs compare to buying new.
| Repair | Typical Cost | Percentage of New iPhone 17 Pro Max (£1,199) |
|---|---|---|
| Battery replacement | £50 to £80 | 4% to 7% |
| Screen replacement | £120 to £200 | 10% to 17% |
| Charging port | £40 to £70 | 3% to 6% |
Even a screen replacement and a battery swap together cost well under a quarter of what a new flagship costs. If the phone works well apart from one or two worn components, repair is the clear winner.
The decision tips toward replacing if the phone has multiple serious faults stacking up, if you want Apple Intelligence features (which require the iPhone 17 Pro or Pro Max), or if the phone has irreparable damage like a bent frame or corroded logic board.
Our repair vs upgrade guide covers the full decision framework.
Buying a Used or Refurbished iPhone 15 Pro Max
If you do not already own one, the iPhone 15 Pro Max is now available at significantly lower prices than its original £1,199 launch price. Refurbished units in excellent condition are widely available for £600 to £800 in the UK.
At that price, it is one of the best value iPhones you can buy. You get a titanium build, a 5x zoom camera, and a chip that will run the latest software for years to come.
If you do buy a used or refurbished model, check the battery health before you commit. A phone with Maximum Capacity at 85% or higher still has good battery life ahead of it. Below 80%, you should factor in the cost of a battery replacement on top of the purchase price.

Frequently Asked Questions
Is the iPhone 15 Pro Max still worth using in 2026?
Yes. The A17 Pro chip is still fast, the camera remains excellent, and Apple will continue providing software updates until at least 2029. The most common issue after three years is battery degradation, which is a cheap and easy fix. Unless you specifically need features like Apple Intelligence (which requires 12 GB of RAM), the 15 Pro Max is still a very capable phone.
How long will the iPhone 15 Pro Max receive software updates?
Apple typically supports iPhones for six to seven years. The iPhone 15 Pro Max launched in September 2023, so you can expect updates until at least 2029. That means three to four more years of security patches and new features from the time of writing.
How much does it cost to replace the iPhone 15 Pro Max battery?
A battery replacement for the iPhone 15 Pro Max typically costs £50 to £80 at an independent repair shop like Phone Clinic. The repair takes under an hour and your data stays on the phone. Apple’s own battery replacement service costs more. Either option restores the phone’s battery life to near original performance.
Does the iPhone 15 Pro Max support Apple Intelligence?
No. Apple Intelligence requires 12 GB of RAM, and the iPhone 15 Pro Max has 8 GB. The full Apple Intelligence feature set is only available on the iPhone 17 Pro and iPhone 17 Pro Max. The 15 Pro Max does receive other iOS updates and improvements, but not the on device AI features that Apple Intelligence provides.
Should I repair my iPhone 15 Pro Max or buy a new phone?
If the phone has a single fault like a cracked screen or a worn battery, repair is almost always the better option. Even the most expensive common repair costs less than 20% of a new flagship phone. If the phone has multiple serious faults or you need features only available on newer models, upgrading may make more sense. Our repair vs upgrade guide covers the full decision.
