Does anyone do decent high capacity batteries?

I have an iPhone X which I am thinking of getting a new battery in and sticking with it for a while. I see online there are plenty of people offering larger capacity batteries, but probably just Chinese knock offs, does anyone do a decent high capacity battery or should I just stick with a standard replacement through apple?

Standard replacement through Apple. High capacity batteries fitted into the same volume are a lie.

Unless those cheap battery makers have access to a new battery chemistry that Apple doesn’t have access to and are selling it cheap? That is sarcasm BTW. Its not going to happen.

My Mrs got a cheap replacement battery from a dodgy shop. I told her not to, but she never listens. That battery started bulging in 3 months and took out her display. So she basically ruined her phone to save £50.

Genuine Apple battery replaced through their battery replacement program everytime.
