15800mAh Battery for iPhone 6S Plus, New 0 Cycle Upgraded Higher Capacity Replacement Battery for iPhone 6S Plus with Full Set Repair Tool Kit, Model A1634, A1687, A1699

I recently replaced my iPhone 6S Plus battery with this one, and I’m extremely satisfied with the results. The new battery shows 100% capacity, and my phone now easily lasts an entire day without needing a recharge — even with moderate to heavy use. It’s like having a brand-new phone again! Performance has noticeably improved, with no overheating or sudden drops in battery percentage. The battery charges efficiently and holds power consistently, which is a huge relief after dealing with a weak original battery. Installation was moderately challenging — I’d rate it about 7/10 difficulty. The included tools were useful, though I ran into one stripped screw that made things trickier. Watching a short YouTube guide really helped, and once installed, everything worked perfectly. Overall, this replacement battery is a great value for anyone wanting to extend the life of their iPhone. It performs exactly as advertised, offers long-lasting power, and gives your phone a second life. Highly recommended!

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.

It can standby for a couple days but decline quickly if I use youtube or other entertainment.

Don't buy this battery it got swollen in a couple months and then you can't return it. Wasted of money.

worked great easy replacement can't speak to longevity. does seem to get to warm during charging

very good product

perfect fit

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.
