JUBOTY Battery for iPhone 7 3800mAh, Li-ion New 0 Cycle Internal New Upgrade High Capacity Battery Replacement for iPhone 7 Model A1660 A1778 A1779 with Professional Repair Tool Kit

My mother in law's Samsung Note 3 that I had given her, which I had previously replaced the battery with an extended battery, was running out of power fast and never fully charging. She had that battery like 2 years. We bought this one, it fit perfectly and came with a special back to fit the extended battery and as a bonus they also sent a phone case. That was a nice touch as you can't really find any to fit with the big battery. It's been a couple weeks now and it's still going great and holding up supercharged. I am very happy with the super fast shipping. Let's face it, when you need a new cell battery, you would rather pay a little more to get it asap, which Amazon can provide

so far this battery has held its charge and was easy to install

I have 26% remaining after an overnight full charge with minimal use today. My old 80% capacity iPhone 7 original battery was better. I was skeptical about it being "high capacity 3800 mAh" in the same size as factory, I was right. What a waste of time and money. This thing is going back!

Overall good experience with the battery and replacement kit. 1 star lost because the suction cup they gave was warped and would not hold to the phone - I had to use the squeegee suction cup from my shower squeegee which was big and bulky and difficult to use but worked. Watched a video online that walked through the replacement process.I have not run the battery through a full charge yet so I do not know how well the battery life lasts. Seems to be quality battery though - will update if any issues with battery.

I was hesitant to purchase this package at first. But I did, and it was worth every penny. I use my phone quite a bit, and this battery pack lasts me on average 1.5 days, 2 if I use it a little more sparingly. The case that comes with it is also surprisingly high quality.

I have an old iPhone 7 and battery was draining fast. I bought this battery and had it installed at a local store. First weeks, it lasted 5+ days, now it runs for 2 days tops. I give it a benefit of the doubt because I didn't install it myself.

I had to purchase this battery because the phone that I purchased came to me with a more or less dead battery. Once I install this battery in my Samsung phone, it worked perfectly. Very good price for a battery.

Honestly, this doubled the battery life of my old galaxy note 3. The thickness added is very minimal. The additional weight was nothing, it’s still lighter than newer phones of today. And for the price, I would highly recommend this product.
