Does a refurbished iPhone come with a new battery? At Remobile, you choose. On Remobile product pages (for example the iPhone 14, iPhone 15 Plus and iPhone 16) a battery selector offers a Standard Battery with 86% or higher capacity or a New Battery with 100% capacity. Other sellers work differently, which is why people ask what happens to the battery in a refurbished iPhone, and what else gets replaced inside the phone.
This guide covers battery health, the “Unable to verify” message, replaced parts, genuine versus aftermarket parts, and original versus refurbished iPhones.
The short answers to the most common questions:
- New battery? At Remobile you choose a New Battery (100% capacity) or a tested Standard Battery (86% or higher). Apple Certified Refurbished iPhones always get a new battery; other sellers vary.
- Battery health to expect: 86% to 100% at Remobile. A 90% battery lasts roughly 90% as long per charge as a new one.
- Other parts: Components that fail inspection are repaired or replaced. Ask whether the parts are genuine Apple parts.
- “Unable to verify” message: Apple says the battery could not be verified, so the health reading may not be accurate.
- Check it yourself: Settings > Battery > Battery Health, then Settings > General > About > Parts & Service History.
Does a Refurbished iPhone Come With a New Battery?
It depends on the seller. Apple says its Certified Refurbished iPhones always come with a new battery and outer shell, and that genuine Apple replacement parts are used as needed (Apple’s refurbished promise). Independent refurbishers set their own rules, so the iPhone refurbished battery may be new or may be the original one that passed a health test.
Remobile lets you decide when you order. The Standard Battery option guarantees 86% or higher capacity, and the New Battery option guarantees 100% capacity. Every device also goes through a multi-point inspection that checks battery capacity, charge cycles and charging behaviour, and a battery that fails is professionally replaced. Browse the iPhone 15 collection the iPhone 16 collection or all refurbished iPhones to compare options.
Refurbished iPhone Battery Health Explained: Capacity, Cycles and What to Expect
Apple shows battery health as Maximum Capacity: how much charge the battery can hold compared with when it was new, which is the refurbished iPhone battery capacity you see in Settings. A lithium-ion battery loses capacity as it chemically ages, which depends on temperature, charging habits and charge cycles. One cycle equals using 100% of the battery, even across several days. Apple designs iPhone 14 batteries and earlier to retain 80% of their capacity at 500 complete charge cycles, and iPhone 15 batteries at 1,000 cycles, under ideal conditions (Apple Support).
In daily use, the percentage translates into time per charge. The table uses the iPhone 15’s rated 20 hours of video playback as an example. Real-world hours differ, but the proportions hold.
| Battery Health | Example Video Playback | Where It Sits at Remobile |
|---|---|---|
| 100% | about 20 hours | New Battery option |
| 90% | about 18 hours | Standard Battery (86% or higher) |
| 86% | about 17 hours | Standard Battery minimum |
| 85% | about 17 hours | Below the Standard Battery minimum |
| 80% | about 16 hours | Below the Standard Battery minimum |
So a 90% battery is barely noticeable, 85% costs around three hours of rated runtime, and at 80% you lose a fifth of it. 86% also sits above Apple’s benchmark of 80% capacity after 500 charge cycles (iPhone 14 and earlier) or 1,000 (iPhone 15).
Why Some Refurbished iPhones Show “Unable to Verify” for Battery Health
Under Settings > Battery > Battery Health, iPhone XR, XS and later can show “Unable to verify this iPhone has a genuine Apple battery”. Apple says the health information on that screen may then be inaccurate, because genuine batteries are designed to work with iOS to report charge level and health (About genuine iPhone batteries).
You may also see a label next to Battery under Settings > General > About > Parts & Service History: Genuine, Used or Unknown. Apple says Unknown can mean the part is not genuine, is not working as expected, has not been verified and linked after a repair, or has been modified. On iPhone 15 and later with iOS 18, Used means a genuine battery previously installed in another iPhone, which may not perform as well as a new one. Apple adds that these messages do not stop you from using the iPhone.
Check both screens on arrival, and if you see an Unknown message, contact the seller during the return period. Remobile offers 60-day returns, described on its returns and refunds page.
Refurbished iPhone Parts: What Else Gets Replaced Besides the Battery?
A refurbished iPhone is a used phone that has been tested, repaired where needed, cleaned and graded. Remobile’s inspection covers the battery, display, camera and functions, and a component that fails is repaired or replaced rather than sold as it is. Cosmetic work depends on the grade: Premium (like new), Excellent (minor signs of use) or Good (used, fully functional).
Remobile describes its process in four steps. Secure Reset erases all previous data and returns the phone to factory settings. Full Check-Up has technicians test every function. Refresh & Renew polishes and cleans the device so it looks and feels like new. Certified & Ready means the phone is released only after it passes a final inspection.
The battery is checked for capacity, charge cycles and charging behaviour, and replaced when needed or when you choose a New Battery. The screen, cameras, speakers, microphones, buttons and charging port are tested and replaced if faulty. The housing is cleaned and refreshed.
Genuine, OEM or aftermarket? Apple’s own term is “genuine Apple part”: a part supplied by Apple and installed with its processes, which iOS can verify. Sellers use “OEM”, “original” or “compatible” loosely, and these are not Apple categories. Apple warns that non-genuine batteries can mean lower capacity or unexpected behaviour. Apple Certified Refurbished uses genuine Apple replacement parts as needed, while other refurbishers set their own policies. Before buying from any seller, ask which iPhone refurbished parts were replaced and whether they are genuine Apple parts.
What does not come back is guaranteed water resistance. An iPhone leaves Apple with an IP rating, but Remobile’s product pages say liquid resistance cannot be guaranteed on refurbished units, because seals can degrade over time and through refurbishing. Its device care guide adds that IP-rated phones are not waterproof.
Original vs Refurbished iPhone: What Is the Difference?
The difference between original and refurbished iPhone models is history, not hardware, whether you compare a refurbished iPhone vs original or an original iPhone vs refurbished one. Both run the same iOS on the same hardware generation. A new iPhone is unused and sealed. A refurbished iPhone was owned before and has been tested, restored and graded.
| Feature | Original New iPhone | Refurbished iPhone at Remobile |
|---|---|---|
| History | Never used, sealed | Previously owned, tested and restored |
| Warranty | Apple’s one-year limited warranty | Remobile 36-month warranty |
| Battery | New battery | New Battery (100%) or Standard Battery (86% or higher) |
| Condition | New | Premium, Excellent or Good |
| Price | Full price | Lower, depending on model and grade |
Is it safe? Yes, when the seller tests every battery, states the condition and backs the phone with a long warranty, and the 60-day return period lets you check it yourself. You give up Apple’s own warranty, which the seller’s replaces. A charger is not included, see what’s inside the box. Remobile’s warranty covers battery defects but not normal ageing, as the device care guide explains.
How to Check Battery Health on a Refurbished iPhone
Open Settings, tap Battery, then tap Battery Health (some iOS versions label it Battery Health & Charging). You will see Maximum Capacity, plus the battery’s date of first use and cycle count. Then open Settings > General > About and check Parts & Service History to see whether the battery is marked Genuine, Used or Unknown.
4 Tips to Keep a Refurbished iPhone Battery Healthy
1. Keep it cool. Apple says iPhones work best at ambient temperatures of 16° to 22°C, and that using or charging above 35°C can permanently reduce battery lifespan (Apple’s charging guide).
2. Charge sensibly. Remobile’s device care guide recommends keeping the charge between 20% and 80% whenever possible and avoiding frequent 0% or 100% extremes. Apple says charging every night is fine and that Optimised Battery Charging, on by default, reduces time at full charge, so treat 20% to 80% as a helpful habit, not a strict rule.
3. Use original or certified chargers. Remobile’s device care guide warns that cheap chargers can damage the battery.
4. Avoid low charge in the cold. Apple notes that unexpected shutdowns are more likely at a low charge, in cold weather or with an older battery, and that a stored iPhone should be kept about half charged.
If the battery wears down later, Remobile’s device care guide suggests a professional check or replacement, and warns that DIY repairs can void the warranty.

It depends on the seller. Apple says its Certified Refurbished iPhones use genuine Apple replacement parts as needed. Other refurbishers set their own policies, so ask which parts were replaced and check Settings > General > About > Parts & Service History, where parts show Genuine, Used or Unknown.
What is the difference between original and refurbished iPhone models?
An original iPhone is new and sealed with Apple’s one-year limited warranty. A refurbished iPhone is the same model, previously owned, then tested, restored and graded. At Remobile it comes with a 36-month warranty, 60-day returns and a choice of 86%+ or new 100% battery.
Why does my refurbished iPhone say “Unable to verify” for the battery?
Apple says the iPhone cannot verify a genuine Apple battery, so the battery health information may not be accurate. It does not stop you using the phone. If you see it, contact the seller during the return period.
Does Remobile’s warranty cover the battery?
Remobile’s 36-month warranty covers battery defects but not normal ageing or wear. Unauthorized repairs and third-party parts are excluded, so do not open the device yourself. If you want the most capacity from day one, choose the New Battery option.
Is 86% battery health good on a refurbished iPhone?
Yes. 86% means the battery holds 86% of its original charge, about 17 hours on an iPhone rated at 20 hours of video playback, and it sits above the 80% Apple designs iPhone batteries to retain after 500 cycles (iPhone 14 and earlier) or 1,000 (iPhone 15). Choose the New Battery option for 100%.
How long does a refurbished iPhone battery last?
It depends on the battery you choose, how you charge and how warm the phone gets. A New Battery starts at 100% and a Standard Battery at 86% or higher. Apple designs iPhone 15 batteries to keep 80% of capacity at 1,000 charge cycles under ideal conditions.
How do I know if my refurbished iPhone has a new battery?
Open Settings > Battery > Battery Health. A New Battery should show Maximum Capacity at or close to 100%, while a Standard Battery shows 86% or higher. Settings > General > About > Parts & Service History also shows whether the battery is Genuine, Used or Unknown.
