You can replace an iPhone battery yourself with basic tools, or take it to Apple or a third-party repair shop
The fastest route is Apple: they replace the battery in one to three days at most locations, charge a flat fee (usually $69 to $99 depending on your model), and warranty the work. A third-party repair shop typically costs less but varies widely by location and shop reputation. Doing it yourself takes two to four hours, costs $20 to $40 for a replacement battery and tools, and voids any remaining warranty — but you keep full control and can do it on your own schedule.
Which route makes sense depends on whether your phone is still under warranty, how much you trust a local shop, and whether you are comfortable opening your device. All three paths work; the trade-off is speed, cost, and risk.
Key Takeaways
- Apple replaces iPhone batteries for a set fee with a warranty, usually within three days, but you must visit a store or mail your phone in.
- Third-party repair shops are often cheaper and faster than Apple but quality and pricing vary by location, so check reviews before you go.
- DIY battery replacement costs the least and takes a few hours, but requires opening your phone and will void your warranty if one remains.
- Before any replacement, back up your data and check your battery health in Settings > Battery > Battery Health to confirm the battery is the problem.
Taking your iPhone to Apple
Visit apple.com/repair or call your nearest Apple Store to book a battery replacement appointment. You can also walk in at many locations, though wait times vary. Apple will run a diagnostic to confirm the battery needs replacement, then replace it while you wait or schedule a later pickup — turnaround is usually one to three business days.
The cost is fixed by model: iPhone 15 and 14 are $69; iPhone 13 and earlier models range from $69 to $99. Apple covers the replacement under warranty if your phone is within one year of purchase and the battery has degraded below 80 percent capacity. If your phone is out of warranty, you pay the full fee. Apple also offers mail-in service if no store is nearby — you ship your phone to them, they replace the battery, and ship it back, usually within five to seven business days total.
The advantage is a warranty on the work and no risk of damage. The disadvantage is you lose your phone for hours or days, and the cost is higher than third-party shops.
Using a third-party repair shop
Search "iPhone battery replacement near me" to find local shops. Check Google reviews and Yelp for ratings and customer feedback before you visit. Many shops can replace a battery in under an hour while you wait, and prices typically range from $30 to $60 depending on your model and location.
Quality varies widely. A reputable shop will use a genuine or high-quality aftermarket battery, test the phone after replacement, and offer a short warranty (usually 30 to 90 days). Before you hand over your phone, ask whether they use genuine Apple batteries or third-party ones, and whether the replacement comes with a warranty. Avoid shops that cannot answer these questions clearly.
The risk is that a poor-quality battery or careless installation can damage your phone's logic board or water sealing. This is rare at established shops but possible. If something goes wrong, you have recourse only if the shop offered a warranty.
Replacing the battery yourself
You will need a replacement battery (search your model number on Amazon or iFixit), a pentalobe screwdriver (the five-pointed tool Apple uses), a plastic spudger or opening tool, tweezers, and a heat source such as a heat gun or hair dryer. A full kit with battery and tools costs $20 to $40. iFixit sells kits for most models and includes detailed photo guides for free on their website.
The basic steps are: heat the edges of your phone to soften the adhesive, pry open the screen using the spudger, disconnect the battery connector, remove the old battery (which is glued down), install the new battery, reconnect the connector, and seal the screen back down with new adhesive strips. The process takes two to four hours for a first-timer and requires patience — rushing risks cracking the screen or damaging the connector.
Before you start, back up your phone to iCloud or a computer. Power it off completely. Follow the iFixit guide for your exact model step by step; guides vary by iPhone generation. If you get stuck, you can still take the phone to a repair shop — they will charge more to fix a botched DIY attempt, but it is not permanent.
The advantage is the lowest cost and full control. The disadvantage is the time, the risk of breaking something, and the loss of any remaining warranty.
Checking your battery health before you replace it
Open Settings, tap Battery, then tap Battery Health & Charging. You will see a percentage labeled "Maximum Capacity" — this is how much charge your battery holds compared to when it was new. If it is above 80 percent, your battery is still healthy and may not need replacement yet.
You will also see "Condition" — if it says "Normal", your battery is fine. If it says "Service Recommended" or "Service Battery", replacement is worth considering. If it says "Replace Now", your battery is degraded enough that performance may suffer.
Battery health declines naturally over time. Most iPhones reach 80 percent capacity after 500 charge cycles (roughly two years of normal use). If your phone is older than three years or you charge it multiple times daily, a battery replacement will often restore noticeably faster performance and longer battery life between charges.
What to do before any replacement
Back up your phone to iCloud or a computer using Finder (Mac) or iTunes (Windows). Go to Settings > [Your Name] > iCloud > iCloud Backup and tap "Back Up Now", or connect to a computer and sync. This ensures you do not lose photos, messages, or settings if something goes wrong during replacement.
Power off your phone completely — do not just put it to sleep. This protects the logic board if a tool accidentally touches the wrong contact during replacement. If you are taking it to a shop, mention any water damage or cracks, because these can complicate the job.
If your phone is still under AppleCare+ or a manufacturer warranty, check the terms before you visit a third-party shop — some warranties are voided by outside repair. Apple's standard one-year warranty does not cover battery replacement unless the battery has degraded below 80 percent, but AppleCare+ covers battery service at no cost.
Comparing the three routes
| Route | Cost | Time | Warranty | Risk |
|---|---|---|---|---|
| Apple | $69–$99 | 1–3 days (or 5–7 by mail) | Yes, one year | None |
| Third-party shop | $30–$60 | Under 1 hour to 1 day | 30–90 days (varies) | Low if reputable; quality varies |
| DIY | $20–$40 | 2–4 hours | None | Moderate; requires care and patience |
Frequently Asked Questions
Will replacing the battery erase my data?
No. A battery replacement does not touch the storage where your photos, messages, and settings live. Your data stays on the phone. If you are nervous, back up to iCloud or a computer first — it takes five minutes and costs nothing.
Can I replace the battery myself if my phone is waterproof?
Yes, but it is harder. Modern iPhones use adhesive strips to seal the screen and battery compartment. If you open the phone, you must use new adhesive strips when you close it, or water can seep in later. iFixit kits include adhesive strips. If you are not confident, a shop is safer.
What if I use a third-party battery and it fails after a month?
A reputable shop will replace it under warranty if they offered one. Ask before you pay whether the battery comes with a warranty and for how long. If a shop will not may provide their work, find a different shop.
Does Apple use genuine batteries for all iPhone models?
Yes. Apple uses genuine Apple batteries for all replacements, whether you visit a store or use mail-in service. This is one reason their cost is higher than third-party shops.
How long does a new battery last?
A new battery typically reaches 80 percent capacity after 500 charge cycles, which is roughly two years of normal daily use. If you charge your phone once a day, expect three to four years before the next replacement. Heavy users may need replacement sooner.
