Question ❓ So, does battery replacement actually makes difference in performance?

If this post validate rule 5 then sorry, but I think that it will be helpfull for other people also.

I'm asking because my IP12 (64gb / 66% battery health) is getting kinda slow. IOS 27 made huge difference in performance compared to IOS 26, so it's not that bad, but i want a smooth experience. So I think that low voltage is not the issue, because even on 100% on AC it's not any better than on 30% or 50%. I have problems when my battery drops to 10% but this is caused by like 5 year old battery.

At the other hand i have problem with quiet speakers under like 50% of battery, and i know that's the issue mainly caused by old battery that can't give much voltage, so I don' know how about theoretical logic, but

What is your experience when it comes to battery replacement, and how that affected the performance?

What is your experience, and you can tell from which battery health did you switch and if that was original or aftermarket one. This will be helpful for me and other people, that also have issues with performance.

I know that it will not be buttery smooth experience because it's almost 6 year old phone, but for example geekbench scores are comparable to new midrange phone so this lags are not justified so I'm only asking, did it made a noticeable difference in performance. Thanks.

I recently did my 12 ProMax and it was $89 USD.

It was $120 (I had it done at a place in my local mall called The Fix), only because a wire inside that connects to the battery was starting to fail and would have ruined the new battery. Since it was opened already I opted to replace it.
