New Data connection goes to sleep and is slow to return


May 16, 2022

I am having a really frustrating issue with my recently bought Poco f3. As soon as the phone isn't using the data connection for more than a second or so, it seems to enter some kind of sleep mode. When I want to load something, it can then take anywhere between 5 seconds and 5 minutes for the data connection to be reestablished. Once it is established, the connection is very good and everything loads quickly.

I see on the connection bars that they are full, and the 4g+ is highlighted. The download/upload arrows to the left of the bars are however grayed out, that is until the thing decides to wake up again.

I have checked all the settings I can find under mobile networks and power saving, but I cannot seem to find anything relevant.

Do you have any idea? Thanks a lot!
