S7 battery suddenly dies after replacing it.

[Android Central Question]

Hi, I recently changed my S7's battery with an original one bought on amazon. Since I did that, my phone is suddenly shutting itself off (a moment before the death the battery is charged, even 40 or 50 percent) and the only way to turn it back on is to plug it to a charger, but when I do that, the battery level is 2 or 3 percent. I've already tried to calibrate the battery with the battery calibration app, but it didn't work.

It may be a bad battery.
