IBESTWIN battery for Iphone 6

[ranger1509]

Over the years my Iphone six battery has degraded, I'm not into spending money one replacements or paying alot for "Apple Certified" repairs I could complete in ten minutes at home for a firth of the cost. I also love my iphone six and will not consider upgrading. I went on amazon looking for replacement batteries and I came across this, https://www.amazon.com/gp/product/B07X2WHKM1?pf_rd_r=MASQV8G1BQBYJMJQN1HP&pf_rd_p=edaba0ee-c2fe-4124-9f5d-b31d6b1bfbee, it got my attention because of the large capacity and low price, I know how to replace this battery and wanted to know if you guys know if this battery is reliable and everything it says to be.

 

Additionally, if this battery is to work, is there anyway I could bring the processor back to where it was when it was released. Apple has intentionally slowed down the processor to "Conserve battery" while this is a logical explanation, I doubt it's true.
