No relation to the factory one I had for 3.5 years. After two months, even when fully charged, it falls and the phone shuts off and needs to be charged again. It doesn't even last half an hour. After this, I had to change my phone. If you can install it yourself, you can risk 10 euros. If you take it to a technician who will charge you another 15-20 euros, then maybe it's worth getting a new phone because this battery is a risk.
Edit 11/2/2023: I had left the battery inside the old phone. By chance, I saw it and the phone had swollen from the battery. Luckily, it didn't catch fire and I wouldn't have noticed it where it was!
