Short answer: Repair if the cost is under roughly a quarter of what the phone is worth and the rest of the device is sound. Replace if the repair approaches half its value, if the phone is close to losing software support, or if two things have failed at once. A battery replacement on a phone with years of updates left is almost always worth it; a screen replacement on a device about to lose iOS support usually is not.
The rule, before the numbers
Repair costs vary by model, by city and by whether you use an Apple-authorised centre or an independent shop, so any figure quoted online will be wrong for someone. Check Apple's published service pricing or get a quote from an authorised centre for your specific model.
What does not vary is the decision framework. Work it out in three steps.
- What is the phone worth today? Use current renewed prices for the same model as a reference — see iPhone resale value by model.
- What does the repair cost? Get a real quote, not an estimate from a forum.
- How many years of software support remain? Check how many years of iOS updates each iPhone gets.
Then apply the ratio.
| Repair cost vs phone value | Do this |
|---|---|
| Under 25% | Repair, if two or more years of support remain |
| 25–50% | Judgement call — weigh remaining software life heavily |
| Over 50% | Replace. You are paying half a phone to keep an old one |
Battery: usually repair
A battery replacement is the highest-return repair there is. It is typically the cheapest common service, it restores the thing you actually notice — a full day of use — and it does not touch anything else in the device.
If your phone's only problem is that it no longer lasts the day, and it still receives iOS updates, replace the battery. It costs a fraction of a new phone and buys you two or three more years.
Use an Apple-authorised centre where you can. A non-genuine battery often triggers an “Unknown Part” notice, can hide the Battery Health reading entirely, and reduces what the phone is worth later.

Screen: it depends on the phone's age
Screen replacement is the most expensive common repair, and on older Pro models it can approach a meaningful share of the device's remaining value.
Repair if the phone is recent, otherwise sound, and has years of support left.
Replace if the device is already near the end of its update window, or if the frame is bent or the back glass is also cracked — multiple failures rarely stop at two.
One warning: on iPhones, non-genuine screens can disable True Tone, trigger warnings, and in some cases affect Face ID. A cheap screen is not the saving it appears to be, and it visibly reduces resale value.
When to replace without hesitating
Liquid damage. Even after it dries and appears to work, corrosion continues. Repairs on liquid-damaged boards are unpredictable and often need repeating.
Two or more failures. Battery and screen together usually exceeds the sensible threshold on any older device.
The phone has lost software support. Spending on a device that will not receive updates is money placed on a shortening runway.
Face ID or the fingerprint sensor has failed. These are among the most expensive modules and cannot be transplanted between devices.
The comparison people forget
The real alternative to an expensive repair is often not a new phone — it is a renewed one of the same or newer generation.
If a screen repair on an older device costs a significant share of what a renewed iPhone 13 costs at around ₹33,999, the comparison is no longer repair-versus-new. It is repair-versus-a-newer-phone-with-a-warranty. Framed that way, the answer often changes.
Every Premium Renewed iPhone arrives at 100% battery health with an 18-month warranty — which is longer cover than most repairs carry. Work the numbers in cost per year of ownership.
Before any repair
Back up the device. Note the IMEI. Ask specifically whether genuine parts are being used and get it in writing. And keep the repair invoice — it matters for resale and for any subsequent warranty question.
Frequently asked questions
Is it worth replacing an iPhone battery?
Usually yes, if the phone still receives iOS updates and nothing else is wrong. It is typically the cheapest common repair and restores full-day use for a fraction of the cost of a new device.
When should I replace my phone instead of repairing it?
When the repair costs more than about half the phone's current value, when two or more components have failed, when there is liquid damage, or when the device is close to losing software support.
Are non-genuine iPhone screens a problem?
They can be. Non-genuine displays may disable True Tone, trigger system warnings, in some cases affect Face ID, and reduce resale value. Use an authorised centre where possible.
How much does an iPhone repair cost in India?
It varies by model, city and whether you use an authorised centre or independent shop. Check Apple's published service pricing or get a quote for your specific model rather than relying on general figures.
Is a renewed phone better value than an expensive repair?
Often, yes. If a repair costs a large share of what a renewed newer model costs, the renewed device gives you newer hardware, a fresh battery and a warranty for comparable money.
