Battery for iPhone 7 Plus, Upgraded 7500mAh High Capacity Replacement Battery, New 0 Cycle Battery for iPhone 7 Plus A1661, A1784, A1785 with Complete Repair Tool Kit : Amazon.ca: Electronics

I went from charging my phone 3 even 6 times a day to literally charging it once at night! Really recommend this if your battery isn’t what it used to be. Installation isn't that hard but definitely look up the process on youtube before tackling this.PS: pulling the glue tabs under the battery was the hardest part, I can't stress this enough keep the tabs as flat as possible when pulling them!

after 9 months,when the battery is around 70% charge,it drain itself in second and my iphone die

This product looks easy enough to install but if you have bad eyesight, as in, you wear cheaters (magnifying glasses for reading) you will have a really hard time to install this! The tool included to remove the screen is a 3 sided plastic cutter - I broke all 3 sides before getting around the first corner! They give you a tiny screwdriver with 3 different heads which are NOT marked so had hard time figuring out which head to use, the screws you will be removing (8 of them) are microscopic! Extremely hard to get them back into their holes right side up. The whole process which I read should have taken one to one & half hours took me 3 1/2 hours! Exercise in EXTREME frustration! Then the life of the batter, supposed to last a week....... maybe if you dont get calls, have to use the phone for anything! I scan a diabetes sensor 4X per day, and check fitbit status 4X per day, no calls, no listening to music, no texting, no game playing and I had to charge the phone on the 2nd day. You decide.

I have been replacing batteries an iPhone since the first iphone was released. I have NEVER revived such a well presented battery or such nice included extras. The screwdrivers is lovely to hold and solid metal. I’ll use that for years to come. The tweezers are nicer than the ones I have been using and even the splurger is much nicer and more solid than any plastic one I’ve used.The battery it’s self is well protected during shipping and is a breeze it install. I suggest only use one adhesive strip as easy to replace in future if needed. Don’t hesitate to use this company if you need to replace an iPhone. They even included we code link to instructions for your phone!
