iPhone batteries wear down after a few years and hold less charge. Learn how to check your battery health, when it is time to replace it, and how much it costs.
Check Your Battery Health

Quick Tip: If your phone dies unexpectedly at 20–30% battery or has started randomly shutting down, a failing battery is often the cause even if health shows above 80%.

iPhone batteries are designed to retain up to 80% of their original capacity after 500 complete charge cycles (roughly 1–2 years of normal use). After that, battery health declines, and you may notice your phone does not last as long through the day, shuts down unexpectedly, or charges slowly.
The good news: a battery replacement is typically much cheaper than buying a new phone, and it can make an older iPhone feel like new again. Apple offers battery replacement at Apple Stores and Apple Authorized Service Providers for a set price depending on the model.
Your iPhone tracks its own battery health as a percentage. A new battery is 100%. Apple recommends replacing the battery when it drops below 80% — below that level, performance throttling may kick in to prevent unexpected shutdowns.
Battery replacement takes about 1–2 hours at an Apple Store or authorized repair shop. Apple offers a mail-in service if there is no store nearby. Third-party repair shops also replace batteries, often at lower cost.
After replacement, your iPhone charges faster, lasts longer, and unexpected shutdowns should stop.
