I get less than 4 hours only when gaming. Also, last night my battery only drained 2% in 8h, which is really good. I still think that 8.1.x.0 marshmallow versions were better for battery life
Happens to me too. At one time, it didn't charge at all, after I started Ampere app to check charging amperage. It did charge fast enough before that. I cleaned the usb c connectors and all seems fine now.
This is Mi5 forum, not mi5x. As far as I know, mi5 never had an option to use the sensor that way, only for tapping as a home button, no swipe gestures.
Maybe it was the verification SMS for Mi account. There's no other SMS being sent, as far as I know and I think you are warned when Mi account verification SMS is being sent and you can deny it. Mi account stuff might not work after that...
Last 2 or 3 weekly updates were not good for my battery life. Used to get 6h sot with earlier MIUI 9 versions, now it's about 4h. Standby drain is also higher.
Never had such low sot. Managed even 2 days between charges with 6h sot. Standby drain was worse initially(more than 1%per hour, I think), but got better with use time. Never had less than 4h sot, not even while navigating.
I have a LG with webos 2014. It used to work, but sometimes it was difficult to connect. I never tried since upgrading to MIUI 9. I will give it a try.
This is all over the internet. CPUz does not work well with Nougat. There is a setting to show CPU speed in developer options. While idle, 4 CPU s are not needed, anyway.
You needs to starts updater app and choose reboot to recovery, hoping that you already have some Xiaomi.eu rom already installed, that changes recovery to twrp.
