Should you repair your phone or replace it? We did the math

The new Apple iPhone Duo has done much more than give fire to the conversation around foldable phones. It has also stirred up the conversation around repair costs — with its display replacement costing as much as a new iPhone 18 Pro — and how far we can reasonably take them, with ever-increasing smartphone prices. There is a threshold up until which repairing your phone makes sense, but beyond a point, it’s wiser to just put your money down on a new handset.

And we will discover exactly where that limit falls by comparing repair costs with and without insurance, giving you a realistic expectation of how much it would cost to own your handset in the long run with mounting spare part prices.

Smartphones plateauing was a blessing

We have all noticed that smartphone innovation has sort of plateaued in the last few years. While it may seem like a terrible thing for the market, it’s actually a blessing in disguise for consumers. With smartphones getting incremental upgrades year on year, older flagships don’t feel outdated anymore. They don’t miss out on any big feature that would meaningfully change our lives — it’d honestly take me a close inspection to tell the Pixel 10 and 11 apart.

And with phones receiving fresh OS updates even years into their lifecycles (often on day one in the case of Pixels), sticking to your existing devices isn’t as bad a deal anymore as it used to be. In fact, this extended lifespan has become a solid reason to get your phone repaired because you know it still has a few years of life left in it.

Repair ‘n’ Renew

The most common — and expected — part to wear down over time is the battery. Modern phones can already estimate how much power the battery can hold, helping you put a number to the drop in everyday battery life and general performance you experience as the phone ages.

Depending on how you use your phone, this usually happens between the second and third year of ownership as the internal composition of Li-ion batteries permanently degrades with each charge cycle. The timing matters a lot because it’s a critical moment when you could go either way: buy a new phone or put your foot down and get another three years out of your handset.

I would lean towards the latter just because of how inexpensive and exponentially more rewarding battery replacements are. You can get a new battery anywhere between $100 and $150, including all labor charges and taxes, across brands and phone kinds, be it a normal slab or a foldable. This little investment can instantly breathe new life into your aging handset, and you’ll actually feel the performance difference every day.

Repairs beyond battery

Physical damage to the phone’s frame and display makes the equation a little more nuanced, especially for older phones where repair prices can at times be more than their trade-in values. If you trade in an old Galaxy Fold 5 in working condition on the official store for the newer Galaxy Fold 8, you’d get up to $380, while its exchange value drops to $280 if the display is cracked. For reference, getting the Fold 5’s inner display replaced costs $540.

If you decide to get it repaired, you’d be spending almost double what the phone costs today. Having said that, it’s still much cheaper than dropping another $1,620 on the new model, after trade-in. It’s the most sensible choice in this situation. The math works similarly for non-foldable phones like the Galaxy S Ultra handsets as well, where you can get the display replaced for under $240, compared to shelling out over $1,100 (after exchanging) on the latest Ultra.

What you have to assess is whether the repair cost is reasonable enough and not close to a new (comparable) phone’s price after deducting the exchange value of your broken handset. And as a general rule of thumb, the older the phone, the less sense out-of-pocket repairs make. Because then you are not just dealing with a broken phone but also committing to aging hardware for at least a couple more years.

You can save some cash by getting your device repaired at a third-party store, as long as you can ensure the part is original and their service quality is dependable, because compromising on either would leave you with a less-than-ideal experience. Going with cheaper, non-branded parts is advised only if you want to keep your handset as a secondary burner phone.

What recently spurred the debate around repair prices was that the iPhone Duo’s inner foldable screen costs an outrageous $1,000 — half of the phone’s retail price. For comparison, replacing the Galaxy Fold 8’s inner display would cost you $580, which is still on the upper side per se, but much more reasonable in comparison. Despite the difference, it almost feels like these companies want you to pay a monthly premium for their insurance coverage to avoid these massive repair bills. And considering how pricey repairs and new phones are getting, I think it might be worth the investment.

Insurance can flip the game

Similar to Apple Care+, Samsung and Google also offer their own versions, though their idea remains the same: you pay an upfront or a monthly price to insure your devices, and in turn, it either heavily subsidizes your repair prices or makes them entirely free, like with battery replacements when their overall capacity drops below 80%.

Take the two recent foldables from Apple and Samsung, for example. Under their respective Care+ plans, replacing the same inner display would cost $100 and a $30 service fee for the iPhone Duo and the Galaxy Z Fold 8, respectively. That’s a substantial saving compared to their full non-subsidized prices of $1,000 and $580 per incident. A similar service fee is charged on non-foldable devices as well, though their parts may proportionately cost less compared to expensive foldable screens.

Having said that, paying for this extra coverage makes sense if you don’t use a case and are prone to dropping your phone or work in a high-risk environment to make it worth the upfront investment (foldables are anyway delicate, so insurance is recommended either way). Apple and Samsung Care+ with a fixed 2-year term cost $400 and $350 (with theft and loss protection), respectively, for their 2026 foldables on top of their retail prices. So, you’re essentially looking at a higher $2,250 to $2,400 entry cost.

You can spread it out and get coverage with no fixed time limit for a monthly fee of $20 for foldables and $15 for slab phones. While they don’t put a large dent in your credit card bills each cycle, they do add up over the years. Over three years on monthly payments, you’re looking at a substantial $720 or an even higher $960 over four years, which is almost half the phone’s original price — and that’s excluding the $30–$150 service fee charged per incident.

Realistically, with two major and one minor accidental damage incident over a three-year period, you’d be spending up to $950 ($720 + $100 + $100 + $30) on insurance and repairs. Without Care+, the same repairs would set you back $2,200 ($1,000 + $1,000 + $200) for Apple and about $1,300 ($580 + $580 + ~$140) for Samsung. If your device is prone to total loss, such as theft, covering it with insurance becomes a no-brainer, considering a paid replacement would otherwise be several times more expensive.

Despite substantial savings in either case, I’d personally like to stop paying for insurance after the fourth year. Going beyond that, the diminishing value I get back would make insurance a lot less of a sensible choice and tip the scale in favor of getting a new phone.

Know when it’s time to buy a new phone

There’s only so much you can do to extend the natural life of your phone with repairs. Eventually, it may turn into a ship of Theseus of sorts, with the recycling bin being the only place left for it to go. That’s when you stop trying to salvage it and replace it with a new one.

While financials are one major factor, the psychological side of using a worn-out phone plays a role too. If your handset cannot keep up with the job you rely on it for anymore, and a new phone will, in fact, improve your workflow, it’s smarter to put your money down on a new handset. Real value sometimes lies not in dollars but in terms of time savings and peace of mind. Whether to value one or the other, or prefer a path somewhere in the middle, that’s something I’d leave for you to decide.
