In the iPhone repair and refurbishment industry, battery replacement has long been one of the most frustrating challenges.
The moment a non-original battery is installed, iOS often throws up warnings like “Unable to verify this iPhone has a genuine Apple battery” or “Unknown Part.” Once customers see these messages, trust drops instantly.
The consequences are serious:
Customer complaints pile up!
Return and rework rates increase!
Repair time per device stretches longer and longer!
Refurbished phone delivery efficiency takes a major hit!
For repair shops and refurbishers, the pressure is real.
But don’t worry—today we’ll walk you through several practical and proven iPhone battery replacement solutions to help you solve these problems with confidence.
Solution 1: Cracked Battery — The “Master Key” of iPhone Repair
The Cracked Battery, commonly known as the CK Battery, has quickly become a game-changer in the repair industry.
The DEJI CK Series is one of the most representative examples.
Due to the more complex installation process of this battery, we are currently selling it exclusively to professional repair companies and companies refurbishing devices.
It truly works like a master key for repair shops.
Key Advantages:
* No chip transfer required
* No soldering
* No additional programming
* Battery health displays normally after installation
* No “Non-Genuine Part” or “Unknown Part” pop-up warnings
Battery Health shows 100%, no pop-ups.
How It Works:
Inside the battery is a pre-programmed authentication chip that communicates seamlessly with iOS. This allows the battery to pass Apple Diagnostics and System Configuration, achieving an experience that is extremely close to official Apple battery replacement.
For everyday repair shops and high-volume refurbishers, this solution is a lifesaver:
* Easy installation
* Fast technician onboarding
* Significantly reduced repair time
* High stability and lower return rates
Repair becomes simpler, faster, and far more efficient.
Solution 2: Diagnostic Battery (Status: USED) — A Cost-First Option
If your business prioritizes cost control over battery status display, the DEJI Decode Battery (USED status) can be a solid option.
Features:
* Eliminates the “Unknown Part” warning
* Can run Apple Diagnostics
* System displays battery status as USED
This solution is commonly used in cost-sensitive refurbishment channels where battery status display is not critical.
Limitations:
* Requires explanation to end customers
* In resale markets, it may raise concerns about whether the battery is second-hand
While economical, it may impact customer perception if not communicated properly.
Solution 3: Decode Diagnostic Battery (“Show Genuine Battery”) — A More Customer-Friendly Upgrade
This is an optimized version of Solution 2 with a more favorable system display.
Display Behavior:
Shows “Genuine Battery”
No non-genuine warnings
Higher diagnostic recognition level
Easier for customers to accept compared to plain “USED” status
That said, it is still fundamentally a DEJI decode diagnostic solution, fully compatible with iOS 26.
2026 Diagnostic Battery Market Trend: The Balance Between Quality and Value
By 2026, the diagnostic battery market has largely stabilized in pricing, while clearly separating into **two quality tiers**.
Standard Diagnostic Batteries:
Premium Diagnostic Batteries:
* Japanese or Korean cells (typically from ATL or Samsung SDI)
* 95–100% capacity retention
* 500+ charge cycles
DEJI batteries use top-tier cells from first-line suppliers, combined with TI-based protection circuitry, ensuring system updates do not affect normal operation—even as iOS evolves.
For repair shops and refurbishers, the price difference between standard and premium diagnostic batteries is only a few dollars—but the long-term value is significant. Longer lifespan means:
* Higher customer satisfaction
* Fewer warranty claims
* Lower total operating costs over time
Smart Business Thinking for Repair Shops & Refurbishers
From a long-term business perspective:
* Simple decoding solutions lack long-term stability
* Chip-transfer soldering requires high skill and is difficult to scale
* No-solder, full-diagnostic-compatible solutions are the future
That’s why more and more professionals are choosing mature DEJI Diagnostic & Decode Battery solutions.
They strike the ideal balance between:
* Efficiency
* Stability
* After-sales risk control
Most importantly, they help you deliver real, tangible value to customers—offering a cost-effective alternative to Apple’s much more expensive official battery replacements.
