First of all, all credits go to @Tomoms that kindly created the zip.

Our bacons are getting pretty old especially on the battery side. After using sultanxda rom that was underclocked to 1958 Mhz i noticed a nice improve of SOT without sacrificing performance too much .

Unfortunately, on every other ROM, changing frequencies trough kernel tweaking apps (ie kernel adiutor) results in Qualcomm mp-decision not behaving correctly, cores not going offline and frequencies scaling pretty much messing up.

This zip underclocks correctly your CPU to 1958mhz, without the need of any third party app, hope you ll find it useful.

Again, all credits go to @Tomoms

Let me add that the zip should be universal, that is, I expect it to work on all Oreo ROMs and probably on Pie/Nougat ROMs as well. If it doesn't work on certain ROMs, I'll update it to support all of them.

omgomgomg i was wondering about this for so long !
my fault for not checking this place for 2 years lol. I also used Kernel Adiutor which misbehaved at times, random overheating after settings failing to apply on boot, and noticed mdprecision erros in the logs
1958 MHz is also the frequency i used, how is this all a coincidence ^^
Is it possible to edit a value in the zip to underclock to 2.3 Ghz ? (i don't remember the exact number)
Not that i need it, just wondering. OPO currently pretty dead from weird cpu/power/battery issues, if this fixes I'll be ecstatic

Can the number be set in the `anykernel.sh` file to any reasonable clock speed? such as 1750Mhz? Or does it need to be a specific multiple, or something?

It has to be a valid frequency of the OPO's CPU. You can find a list here: https://github.com/LineageOS/android...974.dtsi#L1548
