Great battery
I'm 72 and was able to install this battery. My old battery was swollen and separated the case so that made it a little easier to open it up. My phone now looks like new and lasts longer on a charge than it did when it was new.

Don't buy this one.
Doesn't come with any instructions. Doesn't come with needed tape for re-attaching back and battery. Haven't got any support from the seller. And most importantly, battery is still only outputting 5500 mah, so no upgrade.

I got a working battery
I bought it and it works. At the time of writing which is 1 month after purchase, it works like a normal battery. The phone detects it as a regular 5000mah battery. However it's getting the job done. If it was listed as 5000mah replacement battery then it would be 5 stars, at least it would be more accurate to the description. Ohh finally it would come with everything listed in the image.
