What to Look for in a Replacement iPhone Battery
- Capacity: Must match or exceed the original mAh rating. Do not accept significantly lower capacity batteries — they will drain faster.
- Cycle count: A genuine new battery should have 0–5 cycles. Refurbished pulls have higher counts.
- OEM-grade cells: Use batteries with genuine-grade Li-ion cells. Cheap cells degrade rapidly and can swell.
- Adhesive strips included: Good-quality replacement batteries include adhesive pull tabs.

If your iPhone is under AppleCare+ and battery health is below 80%, Apple will replace the battery for free. Check your AppleCare+ status at appleid.apple.com before paying for a third-party replacement.

Frequently Asked Questions
How do I check my iPhone battery health?
Settings → Battery → Battery Health & Charging. If Maximum Capacity is below 80%, Apple considers the battery significantly degraded.
Will replacing my iPhone battery fix slow performance?
Yes — Apple's performance management feature throttles processor speed on iPhones with degraded batteries. A new battery restores full performance.
Is it safe to replace an iPhone battery yourself?
Yes, with care. The main risk is puncturing the battery during removal, which can cause it to swell or smoke. Use the adhesive pull tabs rather than prying. If the battery is already swollen, handle it carefully and do not apply pressure.
How long do iPhone replacement batteries last?
OEM-grade replacement batteries typically last 2–3 years of normal use before degrading below 80% capacity — the same as the original.
