My battery drop to zero and now my phone doesn't turn on.

[macleod.exe]

My Xiaomi Mi Mix 3 doesn't' turn on, I have the phone since 2019 and never has a problem. But now the phone doesn't do anything, no led light no vibration, no nothing. I press the volume + power but nothing.
I change the battery recently but that doesn't change anything. Somebody know how can I revive my phone? I need the files.
Sorry for the english, i'm not a native speaker

probably battery died, you most likely need a replacement.
