Such a weird looking Indian site. Low res Chinese banners/pics everywhere. Gave me a headache.
Always looked like that.
Usually what happens is, when people buy new battery out of frustration that their old battery is worn up, in reality their phone has developed a hardware level problem which is called excessive power consumption even in deep sleep, which accelerated their battery wear level.
What you're mentioning here is a hardware defect outside the battery, which is not common. New batteries are rightly expected to drastically improve bb.

My smartphone's og battery got worse with time until one day turned into one puffer fish. Replaced it with one after market battery and the bb is better than ever before. As good if not better than og while new. It depends, on the manufacturer and your luck.
The Frankenstein I bought from
@awestorr still gives me over 6 hours of battery life (SOT I mean, since it fails to enter sleep) and let me inform you that it is ~7 years old and he had gamed on this thing. So hardware degradation affecting battery is not that common, going purely by intuition; unless the hardware in question is the battery itself.
What is up with terrible battery quality in second hand market.
I'll be absolutely honest with you. I am more scared of those noname batteries bursting into flames than anything else.
As to why they are bad, they simply lack the tech to make sth good and prioritise margin over quality.
Do they think selling cheap quality battery once is more profitable than having a good/reputable business.
If I were a noname company like, for example, Mitsu, I'd prefer losing a lot of business by scamming one consumer for a good bulk sum. That's the mentality cuz what I get from one scam is the payment by six different customers at once. If I am like that, I know I don't have any credibility or competence to scale things to something big. So I'd prioritise profit over quality.
