❓ Frequently Asked Questions
What is the Greencell PRO Series and how does it compare to original Apple batteries?
The Greencell PRO Series represents our premium tier of replacement batteries, designed to match or exceed original Apple battery performance. These batteries use genuine Texas Instruments battery management chips, specifically the 27546-A3 IC, which is the same chip architecture found in OEM batteries. This ensures accurate battery percentage reporting, proper communication with iOS battery health monitoring, and optimized charging cycles. The PRO Series also uses original-spec lithium-polymer cells rather than cheaper alternatives, providing the full 3110mAh capacity that matches Apple specifications. Unlike budget replacement batteries that may use recycled cells or lower-grade components, Greencell PRO batteries are manufactured with new high-quality cells and undergo rigorous quality control testing before shipping. Each battery ships with zero cycle count, meaning you receive maximum capacity from the very first charge. The ROHS and CE certifications confirm the battery meets European safety and environmental standards. In practical terms, you can expect battery life equivalent to a new iPhone 11 with all-day performance under normal usage conditions.
What does the TI chip (27546-A3 IC) do and why is it important?
The TI chip refers to a Texas Instruments battery management integrated circuit that handles critical functions for proper battery operation. The 27546-A3 IC specifically manages communication between the battery and the iPhone's power management system. This chip is responsible for accurately reporting the battery's current charge level to iOS so the percentage displayed is correct. It also monitors the battery's health metrics including cycle count, maximum capacity, and peak performance capability that iOS displays in Settings under Battery Health. The chip controls charging behavior by communicating with the iPhone's charging circuitry to optimize charging speed while protecting the battery from damage. Temperature monitoring through the TI chip prevents charging when the battery is too hot or too cold. Without a proper battery management IC, an iPhone may display inaccurate battery percentages, show warning messages, refuse to charge properly, or exhibit unexpected shutdowns. Budget batteries often use generic or counterfeit ICs that do not communicate correctly with iOS, resulting in these problems. The genuine TI chip in Greencell PRO batteries ensures full compatibility and accurate operation.
What does 0 cycle count mean and why does it matter?
Cycle count refers to the number of complete charge and discharge cycles a battery has experienced. One cycle equals using 100 percent of the battery's capacity, though this can be accumulated over multiple partial charges. For example, using 50 percent of your battery on two separate occasions counts as one cycle. Apple designs iPhone batteries to retain approximately 80 percent of their original capacity after 500 complete cycles. A battery with zero cycle count has never been charged or discharged, meaning you receive it in factory-fresh condition with maximum possible capacity. This is important because some replacement batteries on the market are actually refurbished or previously used cells that have been repackaged, and these may already have significant cycle counts that reduce their effective lifespan. A battery with 200 cycles already used would only have approximately 300 cycles remaining before reaching the 80 percent capacity threshold. With our Greencell PRO batteries at 0 cycles, you receive the full 500 plus cycle lifespan and 100 percent of the rated 3110mAh capacity from day one. This translates to multiple years of reliable battery performance under normal usage patterns.
What safety protections are built into this battery?
The Greencell PRO battery includes multiple layers of safety protection to prevent damage and ensure safe operation under all conditions. Overcharge protection prevents the battery from accepting charge beyond its safe maximum voltage, which protects against cell damage and potential swelling. Overheat protection monitors temperature during charging and discharging, automatically limiting current if the battery becomes too warm. Short circuit protection provides instant cutoff if an electrical short occurs, preventing catastrophic failure. Overload protection prevents excessive current draw that could damage the battery cells or connected circuitry. Over-discharge protection prevents the battery from draining below a safe minimum voltage, which can permanently damage lithium-polymer cells. The battery also includes PTC (Positive Temperature Coefficient) protection at the cell level, which automatically increases resistance if the cell overheats beyond safe limits. The high-quality PCB (printed circuit board) incorporates all these protection circuits and is tested with sophisticated equipment to ensure reliable operation. These safety features work together to protect both your iPhone and the battery itself under normal and abnormal operating conditions.
Can I install this battery myself or should I use a professional?
While iPhone 11 battery replacement is technically a DIY-accessible repair, we recommend professional installation for optimal results and safety. The repair requires Pentalobe screwdrivers to open the device and Y000 tri-point screwdrivers for internal components. You need plastic pry tools and a suction cup to safely separate the display from the frame without damaging the fragile display cables. The original battery adhesive must be carefully removed, typically using isopropyl alcohol and pull tabs, without puncturing or bending the battery which could cause thermal events. ESD precautions are essential to prevent static discharge that can damage internal components. The entire repair takes approximately 30 to 45 minutes for experienced technicians. If you lack experience with iPhone internal repairs, professional installation eliminates the risk of damaging your display, logic board connectors, or the new battery during installation. Professional installation also ensures the battery adhesive is properly applied for secure mounting and the water resistance seals are correctly reinstalled. The cost of professional installation is typically modest compared to the risk of causing additional damage that could exceed the cost of the battery itself.
Will iOS show a non-genuine battery warning after installation?
Starting with iOS 14.4, Apple introduced a feature that displays a message in Settings under Battery if the battery has been replaced with a non-Apple component. This message typically reads "Unable to verify this iPhone has a genuine Apple battery" and appears regardless of the quality of the replacement battery. This is a software verification check based on Apple's encrypted pairing system rather than an assessment of battery quality or safety. The Greencell PRO battery will function completely normally despite this message. All battery features work correctly including accurate percentage reporting, battery health monitoring, optimized charging, and peak performance capability. The TI chip ensures proper communication with iOS for all functional purposes. The message does not indicate any problem with the battery and does not affect device performance or battery life in any way. It is simply Apple's method of noting that the battery was not installed by Apple or an Apple Authorized Service Provider using Apple genuine parts. Many users simply acknowledge the message and continue using their device normally with full battery functionality.
How long will this battery last compared to my original iPhone 11 battery?
The Greencell PRO battery is designed to provide equivalent lifespan to an original Apple battery when new. The 3110mAh capacity matches Apple specifications, and the high-quality lithium-polymer cells are manufactured to similar standards. Under typical usage patterns, you can expect the battery to maintain above 80 percent of its original capacity for approximately 500 complete charge cycles, which translates to roughly 2 to 3 years of normal daily use for most people. Daily battery life depends heavily on your specific usage patterns including screen brightness, cellular signal strength, background app activity, and processor-intensive tasks like gaming or video streaming. With a healthy new battery at full capacity, most users experience all-day battery life similar to when their iPhone 11 was new. If your original battery had degraded significantly before replacement, you will notice a substantial improvement in both daily runtime and performance consistency. The battery will also charge faster than a degraded battery because it can accept higher charging rates without protective throttling. Proper care such as avoiding extreme temperatures and not regularly draining to zero percent will maximize the long-term lifespan.
What do ROHS and CE certifications mean for battery safety?
ROHS stands for Restriction of Hazardous Substances, a European Union directive that restricts the use of specific hazardous materials found in electrical and electronic products. ROHS certification confirms the Greencell PRO battery does not contain dangerous levels of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers. This is important for both environmental safety during manufacturing and disposal, as well as user safety during normal handling. CE marking indicates the battery meets European safety, health, and environmental protection requirements. For batteries, this includes testing for electrical safety, resistance to fire hazards, and proper labeling of capacity and voltage specifications. Products bearing CE marking have been assessed by the manufacturer and judged to meet EU consumer safety requirements. Together, these certifications provide assurance that the battery has been manufactured under quality-controlled conditions using safe materials and processes. While these certifications do not guarantee the same longevity as Apple-manufactured batteries, they do confirm the product meets international standards for consumer electronics safety. Our manufacturer maintains these certifications through regular audits and testing protocols.
What is covered under the 12-month warranty?
Our 12-month warranty covers manufacturing defects and premature battery failure under normal operating conditions. This includes significant capacity loss that drops below 80 percent within the warranty period despite normal use patterns, battery swelling or deformation not caused by physical damage, failure to charge or hold charge, inaccurate percentage reporting caused by chip malfunction, and any defects in the battery cells or protection circuitry. To make a warranty claim, you need proof of purchase and a description of the problem you are experiencing. We may request photos showing the battery condition or ask you to check Battery Health in iOS Settings. The warranty does not cover damage from improper installation including punctured cells or torn flex cables, physical damage from drops or liquid exposure, damage from using non-Apple chargers that deliver incorrect voltage, normal capacity degradation after extended use approaching 500 cycles, or batteries that have been modified or used in devices other than iPhone 11.
