Any tips for battery saver on the ThunderRS app? Should we put schedutil for all? I don't have more than 4H SOT on my S20+ and I really regret that I've bought this device

If you have OC to 3016 big and 2600mhz on mid cpu so this is not strange...... on default i have about 8h SOT. 12% per 1hr with wifi on and white theme.

So what should we do, what's the best parameters?

Is there thunderstorm kernel for s21

Reset the kernel with ThunderTweaks, that will help immediately.
Go to Settings and then Restore Application and reboot.

If its already on stock and I still have battery Issues

Nope, sorry.

So maybe some app draining your battery, look at apps usage in any monitoring app. Normally is about 7-9h SOT..depends on unit like S20 S20+ S20Ultra.

No apps is draining, I've looked on the stats and are totally fine...I think I need to downclock my cpu cause I'm not gaming, but idk what are the frequency for this..

Untap Apply on Boot in cpu settings and restart the phone or reset ttweaks data app and restart the phone. If you didnt change anything in initial scripts in init/hw folder so will be at default settings.

E.g. usege with default settings and wifi on, white theme and brightness at 50%.
About 12% per 1hr screen on wifi on and 0.5% in deepsleep - screen off and wifi off.

On default is not optimal, some developers have pre-set the optimal settings at that time. Can you do the same with Thunder Tweaks ?

If not: can you please share your settings with us ?

Thanks, your work is great



@robi101012981
Your consumption is also strongly dependent on your provider and their network expansion. If you are often in areas where there is poor reception or the phone has to switch a lot between 3g and 4g, you have a high battery consumption regardless of the kernel settings.

In Germany already have many transmission towers that save energy. We are slowly switching off 3g because it also consumes a lot of power.

CPU you can take energy_step

Im on default, pre-sets sre in system/etc/init/hw/kernel.sh.

I have a problem with the ROM, I think.
It looks like the system is automatically refreshing itself continuously.
Even when I lock the screen, it keeps pop the screen up. Only when I unlock and lock it again, then the screen turns of, until I open it again then the same problem continues.
Also with certain apps with fingerprint unlock, can't unlock because it keeps refreshing quickly.
Anybody else has this problem and/or know how to fix this?
Got the Galaxy S20 G981B, with magisk 23016, ThunderstormKernel. (will post this also at the Beyondrom topic)

Thanks in advance!

So I Attached a short screen record clip, it happens while being on my phone, but also when the phone is on lockscreen it keeps waking up...
Hopefully somebody has the solution for me!

Got it, FINALLY!

Apparently I'm Settings - Apps - Special Accces - Appear On Top, the app I use 'Pabbl' which uses lockscreen as swipe didn't work with it... Turned it off, and lockscreen worked as normal!

BUT! The above screenrecord video, it still does that sometimes with some apps(with fingerprint unlock) and random refreshing. Hope that it is a setting as well..

Idk but it looks like some rom problem...any debload or changes? Maybe was some wrong with wipe dalvik & cache or was dirty flashed rom. But doesnt look to kernel related.

Help everyone..
Trying to play this GPU intensive game - FF7 final soldier.

The game is slightly laggy at 572mhz at max settings but perfect at 800mhz stock kernel.

GPU freq capped at 572mhz no matter what I tweak.
Set min 800mhz, disabled kernel power saving, gpu dvfs all didn't work.

Cycled each and every gpu governer and disabled any and every battery saving option I could possibly find in all Thundertweaks categories, still didn't work.
Restarted phone upon every setting change still stuck at 572mhz.

Though maybe it was a cpu bottleneck and mazed cpu. Still capped at 572mhz. It should be scaling to 800mhz.


Running this with BR4.0. At this point I'm afraid it could be incompatibility or bug on kernel or rom side.

Stock kernel the GPU scales properly to 800mhz though.

Any ideas greatly appreciated as this is a fantastic kernel and I don't wanna revert to stock

 

[Mucky2]

Can I flash the kernel on my unrooted Stock? I'm on latest A12 UL7 with Stock recovery

 

[Bunsenbrenner]

no ! root is requirement

yes, idk why... Ive changed balanced to max - sensing mode - maybe this is it - i will try set it back to balanced:

in exynos9830.dts file for temperature behavior - maybe max makes max freq capping - I will try - min

I.ve made test one with min value - if You want PM me on TS telegram group.

[email protected] {
		compatible = "samsung,exynos-tmu-v2";
		reg = <0x00 0x100a0000 0x800>;
		interrupts = <0x00 0x1df 0x04>;
		tmu_name = "G3D";
		id = <0x03>;
		sensors = <0x3d>;
		sensing_mode = "max"; // <balance> min max
		#thermal-sensor-cells = <0x00>;
		phandle = <0x17f>;
		};

More info for u-

I've managed to force 800mhz by having thundertweaks in the foreground. It ONLY persists when in the foreground. If running in background, it reverts to a lower frequency.

However, when the game is ongoing, while the gpu is at 800mhz, the usage is at 20 or 30%, and as a result, the game still lags.

Very interesting.

Summary:
1. No persistence in GPU mhz unless foreground, other settings have persistence

2. GPU usage suspiciously low, not utilizing 100%. Either game programming is not optimized or kernel bug not sure.

--
I think OK to keep at balanced cos it really helps with the SOT and I don't wanna sacrifice batt life for 1 game. But would be awesome if able to reliably scale mhz on demand. Do pm me ur discord handle(preferred cos my telegram is always greenified) and I can help test for u keep up the good work dude

On the other hand bug could be on samsung kernel issue and nothing u can do about it but wait for next release, cos oneui4.0 still new af
