If your iPhone doesn't make it through the day anymore, the battery is probably the culprit. Lithium-ion batteries lose capacity with every charge cycle. After two or three years of daily use, most people start to notice through use, not by looking at the percentage on their screen. The phone dies unexpectedly mid-task. It runs hot during a navigation session. You plug in more often than you used to. You can't always tell from the battery icon that something's wrong — you just feel it.
The good news is a battery replacement is one of the cheaper repairs you can make, and for a phone that's otherwise in good shape, it often fixes the problem completely. The harder question is knowing when to replace the battery versus when to just replace the phone.
Check Your Battery Health First
Apple built a diagnostic tool right into iOS. Go to Settings > Battery > Battery Health & Charging. The number to look at is Maximum Capacity. A new iPhone starts at 100% and drops from there.
Apple's threshold is below 80%. At 79% or lower, iOS will display a service recommendation on that screen. At 80% you're technically fine. If you're in the mid-80s and not having noticeable problems, you can probably wait a bit longer. That said, the percentage isn't the whole story. If you're sitting at 84% and can't make it through a workday without hunting for an outlet, that's a real problem we can fix. You don't have to wait for iOS to tell you to do something about it.
If you have AppleCare+ or your device is still under Apple's one-year Limited Warranty, battery issues may be covered at no additional charge. For AppleCare+, coverage kicks in once capacity drops below 80%. The Limited Warranty covers battery issues in some cases as well, though it's less common. If you're not sure what coverage you have, bring it in and we'll check.
Replace the Battery or Replace the Phone?
A degraded battery doesn't automatically mean you need a new phone. If the device is otherwise solid and still getting iOS updates, a battery swap almost always makes more sense than upgrading. A new iPhone could run you at least $600. A battery is a fraction of that.
The case for replacing the phone is when the battery isn't the only problem. A cracked screen, a failing camera, or a device approaching end of software support changes the math. Fixing one thing on a phone with three things wrong rarely stays fixed for long.
Where You Get It Replaced Matters
iPhone battery replacements look simple. In practice they involve removing the screen, carefully detaching an adhesive-secured battery, and reconnecting a series of small connectors without compromising water resistance. The part quality matters as much as the technique.
Third-party batteries vary a lot. Some aftermarket options work fine. Others degrade faster, report inaccurate charge percentages, or cause iOS to display a permanent "service recommended" warning because the battery doesn't pass Apple's authentication check. That warning doesn't mean the phone is broken, but it does mean iOS can't verify what your battery health actually is.
As an Apple Authorized Service Provider, we use genuine Apple parts for every battery replacement. The Battery Health screen works correctly afterward, water resistance is restored, and your AppleCare+ coverage stays intact for any future repairs.
If you're planning to replace the phone soon anyway and just need it to last a few more weeks, or money is tight right now and you need a working phone today, a third-party shop is an option. Just go in knowing the risks: parts quality is harder to verify, iOS may flag the repair, and there's less recourse if something goes wrong down the road.

Frequently Asked Questions
How do I check my iPhone battery health?
Go to Settings, then Battery, then Battery Health and Charging. The number you want is Maximum Capacity. Apple's threshold is below 80% — at 79% or lower, iOS will show a service recommendation on that screen. At exactly 80% you're still in the clear. If you do see that service message, take it seriously.
How much does iPhone battery replacement cost in Fishers?
With AppleCare+, battery replacement is covered at no charge once your capacity drops below 80% — that's 79% or lower. Apple's one-year Limited Warranty can also cover battery issues in certain cases. Outside of either, pricing runs $110 to $130 depending on your model.
How long does iPhone battery replacement take?
Most iPhone battery replacements are done the same day at our Fishers location. We stock batteries for every iPhone model we service.
Can I replace my iPhone battery if my health is above 80%?
Yes. Apple's 80% threshold is when iOS prompts you to service the battery, but it's not a requirement for replacement. If your battery is at 84% and you can't make it through a workday without plugging in, that's a real problem we can fix. You don't have to wait for a service recommendation to do something about it.
How long should an iPhone battery last before needing replacement?
Apple designs iPhone batteries to retain up to 80% of their original capacity after 1000 full charge cycles. For most people that works out to two or three years of daily use. Heavy users may see decline sooner. Lighter users can go longer.
