Iphone 5s 32GB - Battery replacement, experiences, what to buy?

Hello,
There comes a point where my 5S 32GB will need battery replacement. There are different sets on the market, both in Poland and Germany. Does anyone have any experience with specific copies / companies?
Opinions vary, it depends on how you end up, but maybe there are companies that are best to stay away from, and others that are worth recommending?

Thanks in advance for any information and best regards
Konrad

Just out of curiosity, how long did you take?
I have mine for a year and a half.

As for the batteries, I used to mention in four, and I found that the price depends only on the description, for example the word "original" in the description caused the price to soar; but the origin is still one thing: the same factory in the far east.

about 3 years and the battery is already spinning.
As I wrote, I am aware that it will never be original, but I read a bit and in the case of some companies it turned out that the "new" battery has, for example, 300-400 charging cycles.
Therefore, I would rather care about which suppliers to avoid.
I am also wondering what they put in, for example, in such a Media Mark, because the cost of replacement is, for example, EUR 39, or say 2x as much as the purchase of a battery with a set of tools for replacement, but will what the insert be better than what can be bought for self-replacement?

From experience I will tell you that it all depends on what delivery will come from the seller from the "yellow river"
Nobody will publish the names of sellers here.

ATX batteries are good value for money.
