This high-capacity replacement battery offers extended battery life compared to an original battery, while maintaining a professional level of reliability and safety. It is an ideal maintenance solution for repairers who wish to offer increased endurance to their customers, without compromising on quality.

Like all our batteries, it is precisely documented: real characteristics and behaviour in iOS, so that you can undertake every repair with full knowledge of the facts.

A reliable and accurate state of charge

The battery incorporates a Texas Instruments gauge chip that calculates the state of charge accurately and keeps it correct over time. The displayed percentage remains consistent with the actual battery life, without sudden drops or erratic values. Where generic management electronics tend to drift over time (health status that freezes or becomes inconsistent), the Texas Instruments chip continuously recalculates the actual capacity and compensates for cell ageing.

High capacity engineering

The increase in energy capacity is based on a dual technical optimisation, carried out without compromising on safety or physical compatibility:

1. Structural optimisation: The design exploits the dimensional tolerances of the iPhone chassis. The battery dimensions are very slightly increased to occupy unused internal space, which increases the volume of the energy cell.
2. Internal material innovation: The use of latest-generation components (separator, copper and aluminium sheets, casing) that are thinner allows for maximising the volume allocated to the active material, which is responsible for energy storage.

This engineering approach, proven on the market, increases battery life while preserving the cell's safety margins. As with any battery, visual inspection before installation (detailed below) remains the guarantee of a reliable integration.

Compatibility and display in iOS

Depending on the iPhone model and the iOS version, the device may indicate that it is unable to verify the origin of the battery. This behaviour is normal for any battery not manufactured by Apple: it does not affect performance, safety, or the product's lifespan.

The battery health status remains viewable: directly in iOS on recent models, or using workshop diagnostic software on all models. You thus keep full control of the actual state of the battery, before and after installation.

Technical specifications

• Capacity higher than original: capacity (mAh) higher than that of the original battery, for extended battery life.
• New cell, zero cycle: each battery is based on a new, never-used cell.
• Lithium cobalt chemistry: a stable and proven chemistry, guaranteeing consistent performance over time.
• Endurance: several hundred charge cycles under normal conditions of use.
• Texas Instruments gauge: reliable and durable reading of the state of charge and battery life.
• Integrated protections: protection against overcharging, overvoltage, short circuits, and excessive temperatures.
• Pre-installed adhesive: for quick and secure installation.
• CE compliance: lithium-ion polymer battery compliant with European requirements.
• Pre-market checks: each reference is subject to rigorous compliance tests before being placed on the market.

Safety and best handling practices

The manufacturing quality of our batteries is subject to strict controls that manage the risks of intrinsic defects. The rare cases of thermal runaway are therefore almost systematically linked to external factors during transport, installation, or final use.

Respecting best practices by the technician is the key to a reliable and durable repair:

• Mandatory inspection before installation: It is the repairer's responsibility to carry out a careful and meticulous visual inspection of the new battery before installation. This step is crucial and requires your full attention. Look for any anomaly (swelling, trace of leakage, whitening, electrolyte odour) which must lead to its rejection.
• Chassis check: Before installation, ensure that the battery compartment is perfectly clean, without foreign bodies (screws, debris). The slightest roughness can create excessive pressure and damage the battery.
• Internal component pressure: When closing the device, particular vigilance is required. Ensure that no abnormal pressure is exerted on the battery by elements such as the screen clips, which could damage its casing.
• Vigilance regarding chargers: Make your customers aware of the importance of using original or certified chargers. A poor-quality charger can neutralise protection circuits and cause overcharging, constituting a proven risk factor.

Compliance and regulatory obligations

UTOPYA complies with all regulatory obligations relating to the placing on the market of lithium-ion batteries. Each product is accompanied by an EU Declaration of Conformity (DoC), a document attesting that rigorous compliance checks have been carried out prior to marketing, in accordance with European requirements (Directive 2013/56/EU).

As a producer, UTOPYA pays the legal eco-contribution on each battery placed on the market, guaranteeing their management at the end of their life. This approach is part of our commitment to a responsible circular economy and complies with Extended Producer Responsibility (EPR) obligations.
