You have three ways to replace an iPhone battery
Apple will replace your battery for a flat fee at any Apple Store or Apple Authorized Service Provider. You can also mail your phone to Apple and they will send it back with a new battery. A third option is to take your iPhone to an independent repair shop, which is usually faster and sometimes cheaper, but the quality varies by shop.
The choice depends on how much you want to spend, how quickly you need it done, and whether you trust a non-Apple technician with your phone. Apple's official route costs between $69 and $99 depending on your model, takes three to five business days at a store, and comes with a warranty. Independent shops often charge $40 to $80 and can finish the same day, but you lose any remaining manufacturer coverage.
Do not attempt to replace the battery yourself unless you have done phone repairs before. iPhone batteries are glued in place, and prying them out risks damaging the screen, logic board, or battery itself — which can cause the phone to overheat or fail to power on.
Key Takeaways
- Apple charges $69 to $99 to replace your battery and takes three to five business days at a store, or longer by mail.
- Independent repair shops often finish the same day for $40 to $80, but quality depends on the specific shop and you lose Apple's warranty.
- You can find your iPhone model and current battery health in Settings > General > About > Battery Health & Charging.
- Before you go anywhere, back up your phone to iCloud or your computer so you do not lose photos, messages, or other data.
- Apple will not replace a battery under warranty unless the battery holds less than 80 percent of its original capacity.
Check your battery health before you go
Open Settings on your iPhone, then tap General. Scroll down and tap About. Look for Battery Health & Charging near the bottom of the screen. You will see a percentage — this is how much of your battery's original capacity remains.
If the percentage is 80 percent or higher, your battery is still within Apple's normal wear range. If it is below 80 percent, the battery is degraded and Apple will replace it. If it is below 50 percent, the battery is significantly worn and replacement is urgent — a heavily degraded battery can shut your phone down unexpectedly even when the screen shows 30 or 40 percent charge remaining.
Write down this percentage and your iPhone model (also shown in the About screen) before you leave home. You will need both when you contact Apple or a repair shop.
How to get service at an Apple Store
Go to apple.com/support and click Repair & Physical Damage. Select your device type and model, then choose Battery Service. Enter your zip code to find the nearest Apple Store or Apple Authorized Service Provider. Click the location and select a date and time for your appointment.
You can also walk into an Apple Store without an appointment, but you may wait one to three hours. Booking online guarantees a time slot and usually gets you in and out in under an hour once your appointment starts.
Bring your iPhone and a form of ID. The technician will confirm your battery health on their equipment, give you a price quote, and ask whether you want to proceed. If you do, they will replace the battery while you wait or ask you to come back the next day. Apple includes a one-year warranty on the replacement battery.
How to mail your iPhone to Apple
If no Apple Store is near you, go to apple.com/support and select Mail In Repair. Choose your device and Battery Service. Apple will email you a prepaid shipping label. Pack your iPhone in a box with padding, print the label, and drop it at any UPS location.
Apple receives the phone in two to three business days, diagnoses it, replaces the battery, and ships it back. Total time is usually seven to ten business days. You will receive an email when the phone ships back to you.
Do not include the charger, cables, or any accessories — only the iPhone itself. If you include other items, Apple will return them separately and delay your repair.
How to find a reputable independent repair shop
Search online for "iPhone battery replacement near me" and look for shops with at least 4.5 stars across multiple review sites. Read the reviews carefully — look for mentions of speed, price, and whether the phone worked correctly after repair. Avoid shops with complaints about the phone shutting down, the screen not working, or the battery draining quickly after replacement.
Call the shop and ask three questions: Do they use new batteries or refurbished batteries? What warranty do they offer on the replacement? Will they back up your data before they start? Shops that use new batteries, offer at least a 30-day warranty, and back up your phone are more reliable than those that do not.
Ask the price upfront. Most independent shops charge $40 to $80 depending on your iPhone model, with newer models costing more. If a shop quotes significantly less than $40, they may be using very old or counterfeit batteries.
Back up your phone before any repair
Even though a battery replacement should not erase your data, back up your phone anyway. If something goes wrong during the repair, you will have a copy of everything.
The easiest way is to back up to iCloud. Open Settings, tap your name at the top, then tap iCloud. Scroll down and tap iCloud Backup. Tap Back Up Now. Your phone will upload all your photos, messages, contacts, and settings to Apple's servers. This takes 10 to 30 minutes depending on how much data you have and your internet speed.
If you do not want to use iCloud, you can back up to a Mac or Windows computer using a USB cable. Plug your iPhone into the computer, open Finder (Mac) or iTunes (Windows), select your phone, and click Back Up Now. This is faster than iCloud if you have a lot of data.
What to expect after your battery is replaced
Your phone should power on immediately and work normally. The battery percentage may show 100 percent right away, or it may take a few hours of charging to reach 100 percent — both are normal.
Use your phone normally for the first few days. If the battery drains much faster than before, or if the phone shuts down unexpectedly, contact the repair shop or Apple immediately. A properly installed new battery should hold a charge for at least 10 to 12 hours of normal use.
If you had the repair done at Apple, you can check your battery health again in Settings > General > About > Battery Health & Charging after one week. It should show 100 percent or very close to it. If it shows significantly less, contact Apple and ask them to inspect the replacement.
Frequently Asked Questions
How long does an iPhone battery last before it needs replacement?
Apple designs iPhone batteries to retain 80 percent of their capacity after 500 full charge cycles. A charge cycle is one full drain from 100 percent to zero, or the equivalent spread across multiple days. Most people reach 80 percent capacity after 18 to 24 months of normal use, though heavy users may get there in 12 months.
Will replacing the battery erase my photos and messages?
No. A battery replacement does not touch the storage where your data lives. Your photos, messages, contacts, and apps will all be exactly as they were before the repair. Back up anyway as a safety measure, but data loss from a battery replacement is extremely rare.
Can I replace the battery myself with a kit from Amazon?
You can, but it is risky. iPhone batteries are glued in with strong adhesive, and removing one requires heat, prying tools, and steady hands. One slip can crack the screen, damage the logic board, or puncture the battery — any of which costs more to fix than paying for professional replacement. Unless you have replaced phone batteries before, the professional route is safer and not much more expensive.
What is the difference between a new battery and a refurbished battery?
A new battery has never been used and comes with a full warranty. A refurbished battery has been used before, tested, and cleaned, but is not brand new. Refurbished batteries are cheaper and usually work fine, but they have less total lifespan remaining. Ask the repair shop which type they use before you commit.
Do I need to replace my battery if it is at 85 percent health?
Not yet. Apple considers 80 percent and above normal wear. At 85 percent, your battery still holds most of its charge. Wait until it drops below 80 percent or you notice the phone shutting down unexpectedly. Replacing early wastes money on a battery that still works.
