    We use an Original BMS Board + High-Capacity Cell.
    Why does this matter?
    While most factories use cost-effective, third-party solutions like OEM TI or cloned 2-in-1 IC chips—especially in competitive overseas markets—we choose the original board for:

     

    ✅ Superior Durability – Less heat, no swelling, longer cycle life
    ✅ Stable Power Management – Matches the original iPhone’s charging logic
    ✅ Widely Trusted in Chinese market – Preferred by skilled technicians for reliability

     

    A note on transparency:
    • For iPhone 11/12/13/14/15 models, we also use OEM TI solutions, as genuine BMS flex are costly for these 5 high-demand models.
    • Even with original boards, diagnostic functions won’t run—these boards aren’t registered in Apple’s database.

    Excellent product. I have purchased this brand several times in the past and I recommend it: I have always been satisfied. Unfortunately, it can happen that some replacements are defective; in this case, the battery percentage was too low, to the point that the iPhone couldn't charge it. However, the seller was very professional and refunded me.

    At first, I was confused because the battery performance was at 0%, but it turned out to be an error caused by poor battery connector contact. After connecting properly, it works very well. It's great.

    Thank you for the delivery. As you can see from the pictures this is a very good company. But it does not eliminate the non-authentic iPhone battery annoying message. This does not give you a true battery health.

    It is one of the best batteries I have bought; I fully recommend the product and its brand for its incredible quality. 10/10 🤩 🤩 The extra features are noticeable in daily use with the iPhone and I've loved that. 😍 It also comes with its tool kit so you can do it yourself, and it's super versatile and practical, including: screen glue, battery, tools, and a manual. I was able to change the battery of my iPhone myself thanks to the tools provided by the seller. 😁 Recommended seller, thank you!

    The package arrived in two weeks. Everything was included: 3 screwdrivers, a guitar pick, a plastic hook, a suction cup, a gasket, and a battery. I will try to install it myself.

    Καλή ποιότητα και αντέχει ολόκληρης μέρας! Μέσα στο πακέτο ήταν όλα οργανωμένα. Δείχνει κανονικά την υγεία μπαταρίας.

    Excellent item, looks of good quality, now it just needs to be installed to see how it performs...

    Except for the late delivery due to the battery, it seems good overall. I can feel that the battery capacity has increased, but it doesn't seem much different from a new genuine battery. However, it's stable and lasts long, so it seems okay. And after replacing the battery, it definitely works well except for not recognizing the genuine battery. Everything else seems good as described in the manual. It's best to do it as instructed in the early stages.

    제품은 발열도없고 좋습니다. 다만 저는11프로 대용량 3480을 샀는데 자가교체후 3u로 확인해보니 설계용량이 3028 실제용량 3076으로 대용량이 아니라 기본용량이 배송이 되었습니다. 상자에는 대용량 울트라로 써있고 교체할태 배터리에3480이라 써있던거같은데 실제 컴퓨터로 확인하니 일반기본배터리 용량 이네요. 저만 그런걸수있으나 구매하시는분들 반드시 컴퓨터에 연결해서 확인하세요.

    It's really good.
    The capacity is also larger than the original.
    After replacing the battery and flashing it once, the battery error message does not appear (based on iPhone X iOS 16.7.12).
    It's quite frustrating that it takes a long time to charge due to its large capacity! !

    Replaced with 13, does not recognize the battery. I would like these issues not to exist, but alas...
