[Upgraded] Battery for iPhone 6S, (New Version) BOANV Ultra High Capacity A1633/A1688/A1700 Battery Replacement with Professional Replacement Tool Kits

I only installed the new battery a couple of weeks ago so I can't speak for its longevity, but as of now, it is working perfectly. This is a good, complete kit for installing a new battery in an iPhone 6s. Before this new battery, I would have to charge my phone every night and usually at least once during the day. Since installation, I have only charged my phone every other night. I can't say for sure since I have had this phone so long but I think this replacement battery actually lasts longer than the original did. The installation is not difficult but I would highly recommend finding a good installation video on Youtube. I looked at several and I felt the clearest and most helpful one was by "RickMakes - Replacing the Battery in an iPhone 6s".

5 star purchase! I have twice the battery life than when I purchased the phone new. Easy to follow instruction video for each phone. I changed 2 batteries in under a hour. Hardest part was cracking the case open. I did require a razor blade to break the seal. Caution and persistent and then success. All tools included. I’m super happy with my purchase and outcome. Money saved and learned something new. 10 STARS!

This was exactly what I needed to replace my IPhone battery. The old one was on it's last legs, barely holding a charge. I watched numerous videos online to understand what I needed to do and saw what tools and supplies were necessary to do a batttery swap.This kit had all the necessary tools and made the battery replacement a breeze. So far, after over a year the phone is holding it's charge like it did when new. I fully recommend this item.

The instructions were poor and didn't address the gasket they provide for resealing the front back onto the base of the phone. Look at other videos until you find one that goes through step by step. The gasket never did go on properly so now I'm extra careful about dirt and dampness. The lightning port didn't work at first - some more videos on that topic suggested I had unseated it's cable in the process so that was easy to fix.For some reason the home button was no longer properly recognized after the battery was installed. It worked but required extra steps to open the phone. I replaced the home button with a generic version (less than $8) which works but isn't as consistent as the original.The battery has met my overall objectives of longer working life on each charge - better than ever. This will allow me to postpone moving up to a new iPhone version until I'm confident Apple has overcome the 'dropped call' criticisms I've seen in the reviews.

This battery provided great tools and even instructional video links so that I could replace my battery in my iphone 6s. I did it in less than 15 min. I was surprised how easy they made it and would definitely purchase this again. I have not had the battery in long enough to determine the health of the battery but the battery lasts several hours without being recharged.

Looks like this battery is only for one time use. Installed it yesterday and it was at 60%. Plugged it in to charge using various chords and plugs but continue to receive alerts on the phone that "This accessory may not be supported". The accessories in this kit are all great. The battery itself is trash.

Great product, the improved battery life is awesome. It’s like a brand new phone again. Comes with all the tools needed to replace the battery. The video recommended for instructions was very helpful.

Battery kit includes everything you need to change out you r iPhone 6s battery.Note: Battery arrived with a charge at 65%The claimed capacity at 2700 does not show up during testing.Battery capacity is reporting as 1715 as a new Apple stock battery would.Now this may be something in the chipset that tricks the iPhone into accepting the battery so when apps are used to benchmark the correct Apple spec is presented while holding some level of reserve. If this is what is happening we can assume a longer timespan for battery life over time. If not then we have a brand misrepresenting the product being sold here on Amazon.
