Everything You Need to Know About iPhone Battery Care & Replacement
How to keep your battery healthy, spot the warning signs, and when a $59 battery swap can add three more years to your iPhone.
How to Care for Your iPhone Battery
iPhone batteries are lithium-ion cells, and like the tires on a car, they are designed to wear out over time. Every charge cycle — one full charge from 0% to 100% — counts against a finite total. Apple designs iPhone batteries to retain up to 80% of their original capacity at 500 complete charge cycles under normal conditions. That said, how you treat the battery in between those cycles has a real impact on how fast it ages.
Four Signs Your iPhone Battery Needs Replacing
Here’s a question we get constantly: “How do I know if it’s actually the battery, or if my phone is just old?” In most cases, if your phone is three or more years old and showing any of the following symptoms, the battery is the first thing to address — and often the only thing that needs addressing.
- Use the on board diagnostic tool within the iPhone itself. Just navigate the Settings > Battery > Battery Health. Once there, check under Maximum Capacity. If this number has fallen under roughly 82%, it time to consider replacement.
- Have you noticed diminished performance of the operating system? iPhones prioritize battery life over performance and in doing so will throttle the operating system in order to prolong battery life. And so replacing a failing battery will actually speed up your device.
- Does the battery display erratic battery percentage? This is an indication that the battery isn’t regulating the power properly and will soon need service.
- Does the battery get overly warm when on the charger. This is another indicator that the battery isn’t managing power appropriately.
Many customers come in expecting to need a new phone only to leave with a battery replacement that costs under $100. If your iPhone is an X or newer and runs the latest iOS, the hardware is almost certainly fine — the battery is the only part that wears out on a predictable schedule.
OEM vs. Aftermarket Batteries — Which Is Right for You?
Once you’ve decided to replace your battery, the next question is what type of battery to use. As an Apple Certified repair partner, All Mobile Matters offers both OEM (Original Equipment Manufacturer) batteries sourced directly through Apple, and high-quality aftermarket batteries for customers looking for a cost-effective solution. Here’s how they compare:
| Feature | OEM Battery | Aftermarket Battery |
|---|---|---|
| Quality | Highest quality available — manufactured by Apple’s supply chain | High quality — tested to meet performance standards Great value |
| iOS integration | Complete — all battery health metrics work in Settings | Most features supported — some health metrics may show a notification initially |
| Guarantee | 90-day warranty Standard | 120-day warranty Longer coverage |
| Cost | Up to 60% more expensive than aftermarket | Lower cost — starts at $59 Best value |
| Availability | May need to be preordered for some models | Regularly stocked for all major models Ready today |
For most customers, the aftermarket battery is the right call — it delivers excellent performance, comes with a longer guarantee, and is available the same day. OEM batteries make sense if you’re particularly sensitive about full iOS integration metrics, or if you’re planning to resell the device and want to document a factory-equivalent repair.

06. The Environmental Case for Battery Replacement
There’s a case beyond cost and convenience for choosing repair over replacement. Consumer electronics are one of the fastest-growing categories of waste in the United States, and smartphones contain materials — rare earth metals, lithium, cobalt — that carry a significant environmental costs to mine and manufacture. Choosing to replace an iPhone battery instead of discarding the device keeps a fully functional piece of hardware out of the landfill and avoids the environmental cost of manufacturing a new phone. For an Arizona household that upgrades every two to three years anyway, a $59–$129 battery replacement that extends the device’s life by another three years represents a meaningful reduction in electronic waste — and it pays for itself in months compared to a new phone payment.
If your iPhone is running slow, draining fast, or showing battery health below 82%, a battery replacement is almost always the right first step before considering a new device. It’s fast, affordable, and in most cases, it will make your phone feel new again.
