When Your iPhone Can't Make It Through the Day: Is DEJI a Good Alternative to Apple's Battery

If your iPhone often dies halfway through the day, replacing the battery is the most straight forward fix.
But the bigger question is: who should replace it?

Apple? DEJ? Or a local third-party repair shop?

The decision isn’t just about price — it also comes down to performance, safety, iOS compatibility, long-term device health, and convenience.

With Apple’s repair fees climbing higher each year, many users consider DEJI’s DIY kits(DEJI Battery Shop) or local repair shops that use aftermarket parts.

So how do these options really compare?

Apple Official Battery Replacement: Excellent Quality, Higher Price

Apple offers battery replacements through Apple Stores, Authorized Service Providers (AASP), or mail-in service — all using genuine Apple batteries installed by certified technicians.

Why people choose Apple:

Top-tier reliability: Apple’s batteries are engineered for each specific model and tested for cycle life, heat management, and power efficiency.
Perfect iOS integration: Health data is fully accurate and you won’t see any “unknown part” warnings. (DEJI’s Diagnostic Series also avoids warnings.)
Professional resealing: Your device is properly closed and stays water-resistant (if applicable).
Best long-term performance and safety

Why people don’t choose Apple:

Price:
  As of 2024, Apple charges $99–$129 depending on the model.
Less flexibility:
  You need an appointment or need to mail the device — not ideal if you want a quick fix.

Generic Third-Party Batteries: Cheap, but a Gamble

Not all third-party batteries are created equal. Many ultra-cheap options cut corners on materials, testing, and safety.

This can lead to:

Rapid battery degradation
Inaccurate battery health reports
Swelling or overheating
iOS compatibility issues
Poor charging performance and short lifespan

They’re cheap, but often not worth the risk.

So, Which Should You Choose?
