BaikalOS Pie PowerSave: minimize your battery drain.

BaikalOS is our Android custom ROM variant with powersave and stability as #1 priority.
Based on the Ground Zero Android Open Source Project (GZOSP) and enriched by our developers with lots of custom enhancements and powersave features. BaikalOS isn’t better, just powersave.

Battery rock solid like frozen Baikal ?! .

Will try soon. Thank you all.

Edit: Installed. Any way to remove the headband "search" bar other than using another launcher?

@andr68rus Could you fix 1)the sim change after reboot. I can't turn on data unless I go to settings and do it manually by selecting data over "ask for permission"
2)on aggressive idle, system terminates white listed apps too.


EDIT: After reboot, both Wi-Fi and data don't activate from notification titles. And on-call sound is really low.
++ Wi-Fi can't connect it says connecting and then the network gets tagged as "disabled".

If I understand correctly, the BaikalOS installation should be as follows:
1-we put on the phone: LEX820 (X2_CN) 20s, rom Baikal, TWRP, GApps and Magisk
2-reboot: install new TWRP, then LEX820 (X2_CN) 20s
3-wipe
4-Flash ROM BaikalOS and GApps
5-Reboot to ROM and finish setup
You can not install this rom directly on the installed lineage, aex or pixel. Does the phone have to be treble.
