Replacement batteries for iPhone are divided into three main technical standards: Service Pack (factory originals), TI (integrated with the Texas Instruments power management controller), and Prime (high-density new cells). Choosing the ideal component depends on the intended balance between authenticity, cycle reading, and repair cost.
01 · Product Categories
Understanding market standards
In professional mobile device repair, the battery is one of the components with the highest impact on user experience and safety. Knowing how to identify the specifications of each range is essential to offering a transparent and durable service in the lab.
Service Pack
100% genuine parts with official factory serial numbers. They guarantee immediate compatibility with the device's original ecosystem and absolute stability in fast-charging routines.
TI Range
Equipped with the original Texas Instruments microcontroller on the protection board (BMS). They allow precise cycle reprogramming and rigorous telemetry communication with the motherboard.
Prime Range
Grade A+ virgin lithium polymer cells with rigorous nominal capacity and an excellent thermal durability ratio. They are the perfect solution for an economical and sustainable repair.
Lab Note
Since the launch of the iPhone XS, battery replacement displays an unknown part warning in iOS if the original microcontroller is not reused. For customers who demand the visualization of battery health without alerts, TI cells allow the transplantation of the original BMS with high technical stability.

Technical specifications side by side
Each line responds to a specific bench technical need:
| Criterion | Service Pack | TI Range | Prime Range |
|---|---|---|---|
| Controller (IC Gas Gauge) | OEM Proprietary | Original Texas Instruments | HQ Aftermarket Microcontroller |
| BMS Transplant Compatibility | Possible | Excellent | Recommended for spot welding |
| Charge Retention after 500 cycles | Greater than 80% | Greater than 80% | Approx. 80% |
| Usage Segmentation | Official Restoration | Expert Technicians | High Cost-Benefit Repairs |
03 · Best Practices
Installation and safety procedure
-
Step 1
Discharge and safe isolation
Discharge the device to a level below 20% before opening the chassis. This reduces the risk of combustion if the old cell is punctured during adhesive removal.
-
Step 2
BMS and flex cable transfer
If opting for TI or Prime range welding cells, perform the transplant using nickel spot welding and protect the terminations with insulating thermal Kapton tape.
-
Step 3
Post-repair calibration
Connect the smartphone to continuous power until it reaches 100% charge, keeping the charger active for an additional two hours to stabilize management system parameters.
