    The battery has brought my phone back to life. It doesn't come with the stick strips though, so now it slightly moves in my phone.

    I was very excited when this battery arrived with all the tools necessary to install it! The tools were not in the description, so this was a welcome surprise that saved me the cost of paying to get it installed. The installation took a while, but all is working well. The battery's maximum capacity shows to be at 100% when I look under Battery Health on my iPhone 6.

    Installation went well, no force was needed. The screws differ in length so I used a piece of double sided tape to keep them organized. A bright light is helpful.

    Bought a replacement battery for my I Phone 6. When it came in Best Buy informed me they wouldn’t install it. Why would anyone sell phone batteries and not offer installation. There were several other nearby vendors willing to install a battery but required the battery be bought from them. So I have an extra battery as a paper weight

    I was under the impression that this battery came with tools. One of the reviews above says that is comes with tools. This battery did not come with tools. The only tools I have found in order to replace the iphone 6 battery come with batteries. So now I have to order another one.

    Online Best Buy said that this was the battery I needed. However, one cannot use this battery for Apple products at Best Buy so it was a wasted purchase.

    Without using my iPhone at all, this battery drains within 6 hours.
