What is the ideal battery for your iPhone

Key takeaways

  • Choosing the right battery depends on whether you want a quick direct replacement or to perform micro-soldering with BMS transplantation.
  • Micro Wire offers only three validated qualities: Micro Wire Selected, TI Chip, and official Service Pack.
  • For most bench repairs, the Micro Wire Selected range offers the ideal balance of reliability and ease of installation.
  • Any replacement without transferring the original controller board generates an unknown part notification in the iOS system.

01 Available ranges

The three battery options in the Micro Wire catalog

In our lab in Praia de Mira we do not commercialize inferior technology cells because they frequently fail charge retention tests. We work exclusively with three well-defined product tiers to meet different technical demands.

The Micro Wire Selected range is based on laboratory-validated independent batches, ready to assemble and suitable for Apple system configuration when indicated. TI Chip batteries integrate Texas Instruments controllers for stable voltage measurements, while the Service Pack corresponds to the official brand part, available only for selected models.

Pros and cons of the Micro Wire Selected option

The Micro Wire Selected line is our most requested part by repair shops and independent technicians due to its practically zero return rate.

04 Procedure

Workbench best practices and validation

The physical integrity of components determines commercial and legal warranty eligibility. A mounting error before diagnosis can render the cell unusable.

  • Verification Confirm whether the exact model and quality match the order description before breaking seals.
  • Pre-test Connect the battery to the motherboard without gluing or removing protective tapes to test initialization.
  • Thermal cycle Check if automatic reboots occur during charge cycles in the first 10 minutes.
  • ESD Safety Always disconnect the battery line before any other flex cable to prevent short circuits on the board.

05 Decision

Which quality should you choose

Identify your repair goal and technical availability to select the right reference in the catalog.

06 FAQ

Frequently asked questions

Why does the unknown part warning appear after replacing the battery?

The iOS operating system pairs the original BMS board with the iPhone motherboard. Without official reprogramming or physical transplantation of the original flex via micro-soldering, the unrecognized component notification appears.

What is the warranty period for batteries at Micro Wire?

The commercial warranty from Micro Wire is 6 months for Service Pack units and 3 months for the remaining qualities. Under Decree-Law No. 84/2021, new parts benefit from a 3-year legal warranty against manufacturing defects.

Can I return a battery if I ordered the wrong version?

Yes, you have 14 days for returns on online purchases, provided the product remains unused, without applied adhesives, and packaged in its original intact packaging.
