It's your fault. Probably you're using pocket detection, double tap to wake, aod...
Nope, nothing of that. With Havoc's kernel the phone has an idle drain of 0.1 % up to 0.3 % per hour. With Quantic kernel it's about 1.5 %.

- WiFi = off
- mobile data = off
- BT = off
- AOD = off
- Pocket detection = off
- DT2W = off
- activated energy saving mode all the time
- almost all apps are restricted

The phone should go into deep doze immediately after the screen is locked. At least it works fine with Havoc's kernel.

When the screen refresh rate is set to 90hz, the system will forcibly restart. May I ask the developer, do you have any plans for a 90 Hz refresh rate in the future?

    Good job, mate. I have long wanted to thank you for the base for the kernel used on Syberia OS. ;)
