Yes, I had to replace battery on 2-3year old iPhone 4S several years ago. And also had battery issues after 3 years on my previous android phone.
Once replaced the iPhone battery on a non apple approved repair shop, it wasn’t good for long. Whatever it was due to the repair shop putting a cheap battery or Apple scumbagery I have no idea.
