What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
You do not have to replace an iPhone battery as soon as its health reaches 80%. Consider the percentage alongside battery life, unexpected shutdowns, performance, and any message in Settings. Below 80% is Apple’s stated AppleCare condition for battery replacement at no extra charge—not a universal replacement rule.
What iPhone battery health percentage means
Maximum Capacity estimates your battery’s current capacity compared with when it was new. As a battery chemically ages, it may hold less charge, so your iPhone can run for fewer hours between charges. Battery condition can also affect peak power delivery; iOS reports that separately under Peak Performance Capability.
To check the information, open Settings > Battery > Battery Health & Charging on iPhone 11, 12, 13, and 14 models. On iPhone 15 models and later running iOS 17.4 or later, Battery Health also shows cycle count, manufacture date, and first-use date. Available details and labels vary by model and software version. Apple’s iPhone battery and performance guide explains the indicators.
When to replace an iPhone battery
Health is above 80% and the phone works normally
If runtime still suits you and performance is normal, keep using the phone and monitor its condition. A percentage above 80% does not make replacement necessary.

Runtime has become inconvenient or iOS reports degraded health
Consider arranging a battery assessment or replacement if you are charging much more often than you want, or if Settings says, “Your battery’s health is significantly degraded.” Apple says an Apple Authorized Service Provider can replace the battery to restore performance and capacity.
Apple says that degraded-health message does not itself indicate a safety issue and that you can continue using the battery. It may, however, accompany more noticeable battery and performance problems. The message is not an assessment of physical damage such as swelling, punctures, or unusual heat.

The iPhone shuts down unexpectedly or reports performance management
An aging battery may be unable to deliver the peak power the phone needs. Apple says iOS can apply performance management to help prevent another unexpected shutdown. Check Peak Performance Capability in Battery Health & Charging and consider service if shutdowns or performance problems are disrupting use.
AppleCare coverage is active and capacity is below 80%
Apple’s service page says battery service is available at no extra charge under AppleCare when maximum capacity falls below 80%. That is a coverage condition, not a general rule requiring every owner to replace a battery at 79%. Confirm that the plan is active and that the device qualifies in your region. Apple’s battery replacement service page provides the current service information.

What 80% means—and what it does not
Apple’s battery-service page ties below 80% capacity to no-extra-charge replacement for eligible AppleCare-covered devices. It does not say that all iPhones must have a battery replaced at that point. If your phone is covered, the threshold may make service worthwhile; if it is not, weigh the phone’s runtime and performance against a model-specific repair estimate.
Apple also publishes cycle-life design expectations. It says iPhone 14 models and earlier are designed to retain 80% of original capacity after 500 complete charge cycles under ideal conditions, while iPhone 15 models are designed to retain 80% after 1,000 cycles under ideal conditions. These are design expectations, not a promise that an individual phone will reach a particular percentage on schedule. Apple notes that actual capacity depends on how the device is regularly used and charged.

Where to get an iPhone battery replaced
Apple documents in-person service through a Genius Bar or Apple Authorized Service Provider, as well as mail-in service. Options depend on location and parts availability. Apple’s online estimator provides an estimate after you select the device and model, but inspection is required to determine the final out-of-warranty fee. Authorized providers may set their own fees.
Apple says its one-year limited warranty covers a defective battery, but not normal battery wear. Consumer-law rights may offer additional protection depending on where you live. Apple describes a service guarantee of 90 days or the remainder of the warranty, whichever is longer; check the terms that apply to your location and coverage.

Compare service options before booking
- Check whether AppleCare or warranty coverage applies to your device.
- Get a model-specific out-of-warranty estimate and ask whether inspection could change the final fee.
- Confirm whether the provider is Apple or Apple Authorized, and whether the part is available.
- Compare in-person service with mail-in convenience and verify the service guarantee.
Should you replace the battery yourself?
Apple’s cited guidance identifies Apple and Apple Authorized Service Providers as service routes; it does not evaluate DIY repair, third-party parts, or repair difficulty. If considering a replacement part or repair, verify compatibility with the exact iPhone model and assess the provider and part independently. Do not assume an aftermarket kit is Apple-endorsed.
