Still terrible battery standby drain.

I thought that a 5260mA battery would have lasted so much longer than my Pixel 2 XL's 3520mAh battery while standby, but it doesn't and lasts about the same or less.

Can confirm, I think standby battery drain is the biggest problem of MIUI12 on this device and I really hope it will be fixed in next update(s).
