CPU throttle

So I've gotten my standby time to be pretty good but under moderate use, the device is getting warm and chewing through battery. I.e 4hrs off charger, 40 minutes of screen and only 71% left. I'm stock rooted and removed bloat. Even had stuff greenified (just uninstalled to test now). Is there anything I can do without tripping Knox to slow down the CPU a little? The native power save mode is all or nothing now - they used to let you control which features were enabled on older devices

If your rooted, download a program called Trickster Mod. (All credit to the dev) It allows you to underclock the CPU. Stock value is set at 1.5Ghz. WIthout an overclocked kernel, that value cannot change. However, underclocking is available. And since this device is a true octa-core dropping it to 1.2 Ghz shouldn't be a problem. Also you can change your governor to a conservative one. Stock is ondemand. Conservative and Performance are able to be selected. Changing your TCP congestion to cubic instead of the stock bic, in my experience, gives you a bit better battery life as well. Hope this helps.

Thanks!

The app doesn't say it supports s6, does it definitely work?

You can try kernel tweaker which is also availble on the play store. By the way we do have a Q&A forum so your questions would be better suited over there.

I can't find anything called "kernel tweaker" exactly... Also my question was about apps and this is app subforum. Sorry if that isn't correct

Nexus 4 Fixes: Custom kernel installer mods & more

Intro
Over the past while I've finally decided to fix all minor annoyances on my Nexus 4. Here is a guide where I'll share all my modifications to make Mashmallow on the Mako as good as can be.
Kernel
Kernel Proper
The actual kernel included in this guide is HellSpawn kernel by @spezi77 which is based on hells-Core for Marshmallow, with all up-to-date Linux patches (3.4.112) and Google security patches (June 1). (Although I use, advocate, and absolutely recommend HellSpawn, feel free to use another custom kernel in the installer. You'll have to replace zImage and make your own changes to kernel/sema-boot.sh if your kernel doesn't include the same governors, hotplugs, etc.)
Here are a few highlights of HellSpawn itself:
- Includes the elementalx governor from @flar2 and lightweight mako_hotplug driver from @franciscofranco, which are much better than the stock ondemand governor and mpdecision hotplugs.
- Includes franciscofranco's gamma control, which is a much better default gamma for your screen and can be changed with franco's Nexus Display Control app or other Kernel Tweaker Apps.
- Includes a GPU overclock (400 -> 487 MHz) for when really demanding graphics operations require it.
- Includes BFQ, an optimized version of the default kernel's CFQ i/o scheduler. It helps when Play Store updates occur or when apps perform a lot of disk activity.
- Includes double tap to wake feature, which uses minimal extra battery and is much more convenient than the power key.
- When the screen is off, and not sleeping, only one CPU is active and it's limited to 1 GHz, which helps standby battery life with running background services.
Custom Kernel Installer
(original post with r1 was made on reddit)
I've adjusted many default kernel settings, based on a few years experience of running custom kernels. It uses the optimized elementalx governor from ElementalX kernel and lightweight mako_hotplug from franco kernel, with some of flar2's N5 settings, some of @hellsgod's N6 settings, and some of mine. There are other governors and hotplugs available, but from my experience, these offer the best balance of speed and battery life.
It includes a small, safe, -50 mV undervolt for a bit less heat from the CPU. - a user on reddit reported a reboot with r1, so I've removed voltage settings. It's probably useless to include such a small undervolt anyway. Change voltage settings in an init.d script or Kernel Tweaker app if you wish.
It activates double tap to wake by default, and also turns on power key suspend. If you press the power key with the screen on, double tap to wake will be turned off. Those on custom ROMs or Xposed's GravityBox can activate features to turn the screen off (double tap status bar, lock screen, nav bar, etc.) and keep double tap to wake on. Those without custom ROMs can perhaps use something like Greenify which can remap the home button long-press to turn the screen off.
It includes a patch to sepolicy which allows Viper4Android to work in selinux enforcing mode. You need to have SuperSU installed to have this work.
I've adjusted the io scheduler and page cache for better performance, tuned towards random reads.
It includes stock thermald and a tweaked thermald configuration that scales CPU frequencies up and down a little smoother when your temps get high. It should be noted that most custom kernels disable thermald for their own in-kernel thermal driver. I never liked doing this, as thermald does more than just adjust CPU frequencies - it also throttles GPU, screen brightness, and most importantly, battery charging. When your device gets too hot while charging, the worst thing to do is keep up the current and let the battery go over 45 degrees.
It includes a service to do 'Shared Cpufreq Policy', which lets thermald throttle all cores properly, and also lets the Battery Saver feature work correctly, by limiting all cores. This hasn't worked since KitKat and was one of my biggest annoyances. Many, if not all custom kernels just deleted the Power HAL libraries so battery saver feature doesn't work at all!
Includes Semaphore's 'mpdfake', a service to eat the touch boost spam that the Power HAL generates when not using mpdecision. If a custom kernel does not delete the Power HAL libraries, then your logcat is being spammed and logd process uses a lot of background CPU!
Includes a service to attempt to fix once and for all the location/GPS issues. I'm not going to state it works 100% yet, as I've only had max 24 hr uptime while making changes from the r1 release, but so far so good. Fingers crossed...
Includes a service to give SystemUI and Phone/Dialer higher priority. I haven't had a chance to really test it, as my device is sans-SIM at the moment, but it hopefully will lead to better responsiveness when you receive a call. (Under testing: giving some background processes lower priority, so they don't interrupt app usage.)
Move dalvik-cache to /cache partition and free 300-500 MB:
On each boot, it will check to see if you have a /cache/dalvik-cache folder, and will use it as the dalvik-cache if so.
If you are clean flashing a ROM and want to use /cache for dalvik-cache, create an empty dir in TWRP: /cache/dalvik-cache
If you just want to switch from /data to /cache, copy the /data/dalvik-cache to /cache/dalvik-cache and reboot.
Remember to be careful not to wipe /cache when 'dirty' flashing if you do this!
How to reset the mediaserver process quickly to get videos playing:
While your screen has been on for a few seconds or longer, double press the power key. You'll have to try it a few times to get the timing right, because a quick double press activates the camera in some ROMs. Also you're waiting for the screen to go off, not just dark. Practice a few times in low light, and you'll get the hang of the timing: each press should be followed by about half a second. You'll feel a short vibration when the service resets mediaserver to give some feedback that it's working. If it doesn't run the first time, keep cycling the screen off and on again until you get that vibration.
Remember: you have to start with the screen on, this allows you to quickly check on notifications from screen off without resetting mediaserver.
How to reset the sensors if ambient brightness, auto rotation, GPS, or any other sensors stop working:
Same as above, but this time you do the action twice. That is, screen on - double press power - vibrate once - double press power. You must do the two double presses within a second or two, so a little more practice may be needed. You'll feel two short vibrations when the service resets the sensors.
*** As of mod-r4, the new method to reset both mediaserver and sensors is Hold Volume Up and Power.
How to reset the touch screen if it becomes unresponsive:
If you happen to double tap to wake, the screen comes up, but no touches are being registered, tap on the screen with five fingers. If this doesn't reset it, turn the screen off and on again with the power key, and tap on the screen with both hands, all ten fingers. This will reset the driver and get it going again without a reboot.
Download & Installation
The installer is attached to this post. It's for AOSP ROMs, and uses the UberTC 5.4 toolchain. I'll post up CM versions on request.
Flash the zip with TWRP 3.0.2. If you have made any changes to your Marshmallow ROM (other custom kernels, etc.) you must remember to always flash custom kernels after (dirty) flashing custom ROMs! This is especially important, as if you are missing thermald you're going to have a bad time. FLASH YOUR ROM BEFORE THIS KERNEL INSTALLER UNLESS YOU HAVEN'T MADE ANY CHANGES. You can kill your device without thermal throttling!
Wiping dalvik-cache, and /cache is never necessary when flashing a custom kernel only.

If I want to customise the features, do I only comment out the features which I don't need in sema-boot.sh? Thx!

Hi @xenyz,
Thank you for your new kernel, I have to say that I missed using your projects.
Until now I'm testing it and the only cons I found is that with mako_hotplug when (temp increases) 1026 frequency makes mako very unresponsive.
Is there a way to change this frequency through a init.t script?
Thanks for keeping mako alive!

Carefully edit /system/etc/thermald.conf either in the installer before flashing, or on your device after flashing, and make your changes near the end of the file.
Can anyone comment on whether their location services are working better? I'm still undecided.

I've gotten strange behavior after installing the kernel on my Chroma ROM Nexus 4.
The touchscreen began to have bouts of unresponsiveness, when it never had it prior to installation
Extremely slow on wakeup after a long time in sleep mode. Once again, never had that issue before
Overall lag and slowdown that wasn't present on the stock kernel
I've enabled only D2TW, the new I/O scheduler, 1 core active on sleep, Schedule workqueues on awake cores, and ThermalId
Just now, it did a random reboot. Any idea on what the issue could be?

Could you try it without changing any settings? Force stop the kernel app and reboot.
Do you use any Doze modification apps? Greenify aggressive doze?
Was it a reboot or a SystemUI restart? Did you see the Google bootloader logo? If so, send me last_kmsg

Alright, I'll try it without any settings modified.
I do use Aggressive Doze, could that be conflicting with the kernel? It never seemed to affect the stock kernel besides making the wake take a bit longer, but no lag afterwards.
It was a complete reboot, with the Google logo and everything. Here's the last_kmsg.

I have noticed some erratic behaviour when modifying doze settings. My best guess is that there are certain assumptions made in Marshmallow as to when the device will be in Doze mode, and changing them can have unintended consequences.

That is strange, the reboot was caused by a restart to recovery request. If it happens again, grab another last_kmsg?

Ah crap, about the last.kmsg, I think I know what happened. To pull the .txt file I had to reboot into recovery and use terminal to mount /system and then pull it. It might've pulled data off of that restart.
Currently using the phone with no kernel app active, and it's doing fine. I'll keep you posted if weird stuff happens.
Another thing I noticed is that when I plugged in the charger, the phone would slow down a lot.

That's likely because of the thermal throttle when the battery gets warm. Keep in mind this is actually good for your battery, although annoying when it slows down.
I'm thinking about raising the threshold just a bit in the next release.

Cool. Er, warm. Eh, whatever.
What's your battery temps whilst charging? This is my main concern and where throttle is necessary.
All batteries achieve optimum service life if used at 20°C (68°F) or slightly below. If, for example, a battery operates at 30°C (86°F) instead of a more moderate lower room temperature, the cycle life is reduced by 20 percent. At 40°C (104°F), the loss jumps to a whopping 40 percent, and if charged and discharged at 45°C (113°F), the cycle life is only half of what can be expected if used at 20°C (68°F).

I know it's likely not that useful for those of us with original batteries on older devices, but I try to treat it as best I can.

Charging with screen on, battery temp around 40°C

After more than 24 hours of usage without kernel manager, it ran fine, until it started throttling for some reason. Turns out somehow, the max clock speed was locked to 1000 or so Mhz. I don't know if that was the kernel or the app misbehaving, but I ended up having to reactivate the kernel app to set the clock speed back to normal
There was another spontaneous reboot, here's the last.kmsg.

Thanks for the log. I had a similar reboot but with r14, something in the wakeup_reasons code. I'll have a look through spezi77s commits in kernel/power and see if I can spot something.
I haven't had one reboot in a month or so of using r13, so it's quite strange that you had one so soon, after 24h.
As for the throttle, keep an eye on your battery temperature in Kernel Auditor or whatever and see if it's higher than 40 degrees when you get the 1 GHz max freq.
Edit: I discovered at least one bug in r2 wrt the PowerHal touch boost spam. I'm thinking of posting r14mod3 but I'm not certain r14 is stable yet (see main kernel thread)...

Note 5 fast battery drain

Hello everyone!
Usually I am not active on forums because usually most answers are somewhere in the vast internet. But this time I gave up.
I have a problem with my Note 5's (SM-N920L) fast battery drain. Now it even goes 20% per hour when I use it.
My phone is already about 1,5 year old and I use it a lot, so I read that might be a battery problem so I tried booting it into safe mode and it solved the problem so it seems there is a problem with some app or other functionality, not a battery. So I have factory reset my phone and it was working fine for maybe 3 days, then afternight it drained batterry ultra fast again.
I tried uninstalling any apps that I had installed the day before it broke again, but it didn't help
I have also rooted my phone previously to try to find the reason for fast drain with Gsam stats and WakeLock but I still couldn't find out what's the cause of the problem.
I've seen some posts about deep sleep issue, but my battery drain is qute ok when I'm not using it.
Did anyone have a similar problem? Do you have an idea what can I do to repair it?
Greetings,
Paweł (Paul) Sawicki

Recently I've been trying a different set of tweaks and have the best battery life I've ever had with this device.
DO NOT USE GREENIFY. As it drains the battery a lot these days.
-Rom: PixelRom v6 (Samsung based, all other roms suck for our device, this is odexed and the fastest)
-Kernel: Fuel kernel.
-Cpu governor:
Big: zzmove
Small: interactive
-Flash the lastest Magisk 13 beta.
-Download - then install the following magisk zip plugins through the magisk app:
-(Deleted crossbreeder, as it causes system hangs)
-DozeGMS
-https://forum.xda-developers.com/apps/magisk
Then install busybox (use one which installs successfully). Then hebf from the play store, don't apply any profiles. Disable the extra logging and kernel panics - set it to stay on boot.
-Battery tab - Enable improve battery, low ram device, instant doze.
And I do recommend making your wifi turn off when the screen goes off.
Welcome to three days of battery with frequent usage.

I can only find Crossbreeder Ultra Lite. The Crossbreeder Lite thread says it's for 5.1 and below. What one is right to use?

Check system processes. I found out recently that com.android.systemui uses 15% cpu even on empty home screen and heats up my device without any reason. It was definately the cause of my battery drain. I've been trying disabling apps and unnececery options, and suddenly ui stoped draining and went down to normal 0.5% cpu consuimption. But I don't know exactly what I changed. My latest action was to update all Galaxy Apps.

Actually - don't use that Crossbreeder plugin, it seems to cause system hangs. Everything else though is fine - it'll make the battery life sing!
I also accepted this device just had bad battery life. But now it's never been so good.
IMO Samsung should have used a single processor and use a bigger battery.

Install a hardware monitor app like CPU-z or DevCheck. If you CPU frequency is not coming down from the highest value (for 4 small cores: 1843 MHz and for 4 big cores: 2208 MHz), you are most probably affected by the bug. You can disable fingerprint sensor to conserve battery in that case.

If you are talking about SOT, it's quite normal.
You can't really improve SOT.
It depends mainly on two things : Brightness and Kernel settings. Kernel you cant tamper with without rooting/unlockin your phone, so the best improvement can be achieved via auto brighness.
If you are losing too much battery while phone is idle/screen locked, here are some steps you can follow:
Limit background use of an application from Settings/Battery (Even google play services, notifications still come through)
Disable background data use of apps from Data Usage (Especially facebook/messenger ones, notifications still come through via GCM - use to your own likings though)
Clear Google Play Services cache, as it somehows causes battery drain
Disable location and google location tracking
Disable "Data always on" at developer settings. No point of keeping an active connection while on WiFi
Change network to 3G Only, if your 4G coverage sucks, so it drains all your battery

Auto brightness? Really? I thought that was a battery killer. My brightness is in about 25% most of the time, so, I don't think that is the bigger problem, do you?
Well, thanks both of you guys for the help, and I will follow your instructions(but not the auto brightness one, I don't really like it), Reptant. I will try to remember and report the results at the end of the day.

Yes, that's right. Disable auto brightness, and keep the brightness at around 10%. It is more than sufficient in indoor conditions. Further, disable high accuracy location settings and set it to battery saving or off. You should also turn off WiFi and Bluetooth scanning in location settings.
I personally use a rather far reaching way of force stopping every social media and other news apps after using them (I have never observed any 'misbehavior' as they warn, but it saves a great deal of battery life.). As you can see in the screenshot the battery has lost 7% of charge in 2 hours and it still expects to last for 1 full day.

The suggestions from Reptant above are still valid.
Other than that:
1. Greenify. Set non system apps to shallow hibernation. Try Amplify if you dare.
2. Disable ads. The image/video ads may not occupy a lot of your screen, but they use much more data than text. disabling those ads will reduce the amount of data that the modem needs to download, hence reduce battery consumption. this will have big impact if you surf the web a lot using phone.
3. Change CPU governor to powersave and/or disable some CPUs, reduce GPU max clock speed (you may not like this since it will make the phone laggy)

Question S23 Battery Optimization

S23 has been reported to have excellent battery life.
However, do you guys still optimize it for even better battery life?
Below are what I have done on previous S22 because of it's notorious battery life:
1. Followed [GUIDE] [NO-ROOT] Complete Samsung OneUI Optimization
- Most settings applied
- Phone set up without Smart Switch
- Adaptive Battery disabled
2. Installed [App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods, QS Tiles, Tasker Support and More)
- Adaptive Refresh on Power-Saving mode On
- Adaptive Min 10Hz, and Max 120Hz
- Force Lowest Hz on screen-off (10Hz)
3. Settings
- Sync disabled
- Always-On Display - Tap to show
- NFC, Location, off when not in use
- Power Saving mode 24/7 (Thanks to Galaxy Max Hz app, 120hz still remains)

I am honestly blown away how good the battery life is. I was used to barely 5 hours of sot with my OP7T and now over 10 hours while I have two sims active all the time, bluetooth connected to my watch, AOD always on and rooted device with plenty of root apps running in background all the time. I tried to discharge it during one day, but I failed. Yesterday I had 8:15 sot while 30% left and I am quite a power user (reddit, youtube, social media, 2 hours of pubg, some taking of pictures and more). And I havent even started to optimize the device myself (like uninstall or disable the preinstalled apps, galaxy max hz app and more). I will, once I have more time, but from the battery perspective it is not even necessery.

I checked this topic. It's crazy so many things he disables. The smartphone has nothing smart left..
And the most curious thing is that he kept animations ^^
I was about to suggest you to put 0x to all three dev options
You will feel your phone snappier and I guess it is a battery optimisation.
