CRAFTMANN Batteries - How Good for iPhone?

Question

iPhone

The battery does not hold at all after 1.5 years on the iPhone 5. In a few (~ 4-5) hours, you can drain the entire charge simply by surfing the web and using the VK application.
Came across a fairly expensive CRAFTMANN battery - how good are they? The original, as I understand it, can not be found?
What's up with the originals? They do not exist in nature at all, I understand? Apple doesn't sell them?

Answer 1

Можно на aliexpress или eBay купить совместимый. Я на своем 4-м менял, и на айподах, нормально работали.

Answer 2

Похоже нет.
