After less than a month, the performance/duration of operation dropped to 80% and twice while charging the phone, it consistently showed the battery at 0% (you had to either restart it or plug in the charger again).
I should note that the phone is in a fixed position at home as a secondary device, always on (it only charges when the battery drops below 20%), permanently connected to WIFI, and plays streaming music for 1-2 hours a day (with this usage, the battery lasts a maximum of 2 days, with the screen off)

It worked up to 40% and then the phone would shut off... Very slow and charging... Also, the image is not correct. The battery does not say HUAWEI on it.

The duration at the beginning was at least 15-20% reduced compared to the factory battery and gradually decreased. Charging only with the original Huawei charger as recommended, however, it swelled within 3 months. It should be noted that I did not receive a battery with the Huawei logo as mentioned in the description.
