This is what I have found about this battery replacement set:Pros:- The set contains every thing I need to do a DIY battery replacement.Cons:- Minimum and inadequate instructions, and lack markings on 3 very similar screw drivers- Battery overheating when charging or on high capacity, in spite of repeated tinkering of the tightness of the screws per the "instructions" with the product. I have to get rid of the protective case to mitigate the overheating situation.- Battery capacity is only slightly better than the old one that I have replaced. It drains quickly from 100% down to around 70%. Then it gets a little bit better but no where near a brand new full capacity battery should be.Overall, a lot of effort for very little improvement.

I bought this for my iPhone 6s Plus based on the claim of a 15800mAh capacity, which is completely fake. The original iPhone 6s Plus battery is around 2750mAh, and there’s no way this phone can support over 15,000mAh. It’s deceptive marketing meant to mislead buyers. To make things worse, the kit came with missing components, making installation more difficult. I was eventually able to install the battery with tools I already had, but it was frustrating and unprofessional. Even though the battery is functioning, the combination of missing tools and outrageously inflated battery specs makes this feel like a scam. I wouldn’t recommend this to others, look for a more honest seller.
