If the battery’s capacity is true as the listing says then why is it bad if I replace a 2-3 year old flagship’s battery with a fake one? How is it worse than having an old OEM battery that doesn’t even last the whole day? Apart from this it is nearly impossible to get the original battery for a lot of phones anyways..
And you may say that it would damage your phone, well how often does that even happen?

I have replaced the batteries on iPhone and galaxies with after market batteries as the oem ones went bad. Never had one fail but the lifespan isn’t very long, maybe a year, before you need to change again.
generally they are just poorer quality and hold less charge than what they say on the box
extremely unlikely to damage your phone, but will just not last as long as a genuine battery
The only issue with non-OEM batteries is that you typically don’t know anything about the vendor and their quality standards. It’s fairly easy to buy a replacement that wears out quicker or doesn’t have as much capacity as the OEM one. However, they usually work well enough and tend to be inexpensive, so they are arguably often still worth it.
Not sure if this is true or just a tech urban legend, so if someone actually knows please respond. The microcontroller for the battery can read something similar like a “model number” of the battery and is programmed to optimize it’s battery charging and draw based on the very specific specifications of that battery, when an aftermarket battery doesn’t react exactly how the microcontroller thinks it should it treats it as a battery that is in the process of dying and adjusts to utilize less of the potential charge capacity and increase the charge level when it shuts down. Often times when your phone says 0% charge it’s actually around 10%, that’s to protect the life of the battery; if a lithium ion battery is COMPLETELY empty then you can’t just plug it into a charger, there has to be an initial charge for it to charge up, outdated information but it used to be said that around 15-20% of the cost of the battery was the chemical reactions to put an initial charge in so that it could be charged via standard methods.
Non OEM (fake) phone batteries are usually made with lower quality materials, including cheaper and less reliable cells, which can make them unreliable and less efficient. They may also be made with fewer safety features, which can increase the risk of them overheating, catching fire, or exploding.
A non-OEM battery has likely not undergone sufficient quality control.
On the contrary, the battery production industry will often use battery cells that are known to have failed quality tests for non-OEM batteries, as they are otherwise worthless and expensive to dispose of, so selling them to some sucker that wants to save a few bucks is a best-case scenario if you don’t care about morals.
A battery that has failed quality control may have a drastically shorter lifespan, and more importantly (and the reason why there’s a lot of focus on non-OEM batteries) is that a battery that has failed quality control can spontaneously burst into flames and can also emit toxic gasses during this fire. Obviously, your phone won’t survive that, and depending on where you are at the time, you and your loved ones might not either.
