The battery drains like crazy with Wifi turned on. Its not able to get through the day in standby with wifi enabled and slight usage. With this big of a battery and the usage times you can get with Android on that device this is clearly a bug.

Here a screenshot of battery usage and wifi on idle over the night about 8 hours: image description

Isn't this a documented issue on Sailfish 3 anyways?

No issue on Xperia X, Jolla C, Jolla or Jolla Tablet.

But the same issue on Xperia XA2, the only kind of work-around seems to be keeping the phone always in power saver mode .. it almost makes things normal. I can confirm that on the Intex Aquafish there is no issue with SFOS , So i'm guessing XA2 & Gemini are affected by it

Hi, check if CPU is getting any sleep with WIFI on. That's usually a problem in these cases.

@rinigus How to do that? As you can see from the screenshot sysmon shows a higher cpu usage when the system is on idle.
