Hey guys,

So apparently the cell standby on my 9t + eu stable rom device is also high, like some of other xiaomi device users. Its about the same percentage as the screen usage, which is a bit rediculous to me.

I have tried switching to LTE/WCDMA but that did not seem to help.

I am trying some other settings such as disabling Smart wifi/Mobile data switching, disable AGPS , disable bluetooth such to see the effect. Since nobody is siue about the real cause, lets just try with everything that is even slightly related to mobile radio.

So if you would like to contribute, please provide the following information:
- Do you have outstanding "cell standby" drain while mobile data is enabled?
- During all this time on battery, on you on wifi?( i.e. not using mobile data theoretically)
- is your bluetooth enabled and connected to something.
- Smart wifi/Mobile data switching enabled?
- Network type? ( in *#*#4636#*#* menu)
- AGPS enabled?
- Your region, Mobile service provider/company, and if the mi 9t is missing any lte band with your provider?
- **** Add any info you think can be useful. ****

Lets crowd source the problem and hopefully we can either solve it, or find the cause to the problem and tell Xiaomi so that they can fix it...


Also posted on XDA for hopefully more input.
