Honor 8 Smartphone: Evaluating Battery Replacement Worth and Potential Fake Risks

I have had an Honor 8 smartphone for a year and a half. The battery has declined a lot lately and I am thinking about replacing it. On the internet, I see that prices are between 35 and 60 PLN, so the cost is not high, and the exchange is apparently not difficult.

I just wonder if there is a point to such an operation. I suspect that the battery will be a fake and its parameters may not be better than my current one, the state of which applications determine at about 70 percent. of its original capacity, so some 2,200-2300 mAh remained for use with 3,000 mAh.

Please advise if the exchange has any sense. Thanks.

After replacing in my Xiaomi for a kind of original batteries from Allegro, the battery kept its parameters for a month. After a month I came back to the old one and I still use it.
