According to the log, when autoconnection fails:
Redmi phone sent (Handsfree):
> ACL Data RX: Handle 11 flags 0x02 dlen 17
>

But laptop reply not support:
< ACL Data TX: Handle 11 flags 0x00 dlen 14
#38 [hci0] 9.000848

Then Redmi phone propose disconnection.
It looks like your philip headphone doesn't inquire the handsfree
service, maybe pulseaudio/bluez doesn't support handsfree service well
or enable to do some change to enable it?

I can connect to my bluetooth phone only the first time after pair the

putting into the case, or disconnecting in ubuntu settings), and then i turn on
the phone again (or remove from the case), i cannot connect until I manually
remove from bluetooth devices list in Ubuntu Settings, and then pair it again..
If the Ubuntu/Gnome Settings is opened, i can see the status "connected"
blinks, and fastly change to "disconnected".
