Why are non OEM (fake) phone batteries bad?

150 views

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?

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is COMPLETELY empty then you can’t just plug it into a charger, there has to be an initial charge for it to charge up, outdated information but it used to be said that around 15-20% of the cost of the battery was the chemical reactions to put an initial charge in so that it could be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.
