Anyone else feels battery drains a lot faster on 4.1.2

Korean ver.
Sent from my LG-F180K using xda app-developers app

nope, same with latest 4.0.4

Much better now that it's rooted and setCPU profiles are enabled once again F180L owner.

I actually see a really nice improvement in battery life over 4.0.4. My wakelocks are now 1/4 of what they were. My problem is CPU related - cant get up (to 1.5 ghz... Throttled down to 1.1 almost all the time)

Emm, why do you need 1.5ghz?

I am so confused by this question
Because, like many other people, I bought this phone in part for its processing power. I could have saved a lot of money by getting a slower but uncrippled phone (even stock gingerbread on my Galaxy S was 'good enough' for basic tasks). And yes, I have noticed lags since the speed has been mostly capped at 1.1ghz. I dont expect there to be full speed all the time, but I'd like it to be as snappy as possible when I am doing light activities with it, like web browsing. Why would anybody be content to have a 30% reduction in their phone's capabilities?
UPDATE: the lags I was experiencing seem to have been softare related. They appear to have disappeared after a clean install of JB and manual install of all apps from play store

Oh yeah. What is draining your battery? Is it a specific application or just the OS? If its the OS you can install Better Battery Stats and take a look at your kernel wakelock statistics.

Something wrong with your unit, cause mine one doesnt lag at all even on 700mhz with 2 cores disabled.
Also on 1.1ghz its still most powerfull CPU on the market, but its your way.
I believe you can disable thermal protection in service menu.

Thanks for your advice to check the service menu in more depth but I didnt see the option there. I wouldnt really want to disable it if I could since it does have a use (I'd rather my battery didnt overheat and explode or something ).
Unlikely that there is something wrong with my unit. The lags arent choppy, per se, but more fractional delays that werent there before the upgrade to JB. I probably would not have said anything if I hadn't seen the phone's prior behaviour. And yes, it is my way - I like things to function as they were intended regardless of whether the current performance is "good enough". Lopping off the top multiplier almost entirely seems like a crude way to regulate the operation and temperature of the phone [.. but the new information below suggests that this isnt intentional...] . If I have to compromise at some level, I will gladly take this (nearly imperceptible) loss of function for the improved battery life I am seeing in this ROM.
Update: the weird frequencies I have been seeing have been reported by others using the same rom as me. It seems to be related to the kernel.

Here we go. Just installed setcpu to show you the service settings works. Also im able to set 100% brightness whenever i want.
I used to underclock cpu on ics, but someday ive realized LTE eats battery 10x times faster, so everything ive done with setcpu is kinda useless.
So i just dont care whats going on with cpu freq since it still lighting fast.
Also JB doesnt lag even on old 1ghz devices cause of triple buffer and forced vsync. I think you still should check your phone.
p.s. Latest F180K official rom

Thanks again for your advice, although that screenshot has nothing to do with the service settings and JB does lag quite a bit on older 1 Ghz devices, as I can attest by having JB running on my Samsung Galaxy S. I reinstalled JB as cleanly as possible and manually reinstalled all my usual apps from the play store and the lags seem to have disappeared. Maybe there was a problem with my recovery softare ? I edited my earlier post to reflect this, but the change in CPU frequency is still there.
As I was trying to say before, you and I are using different phones and different roms. It seems to be a recognized quirk with the rom I am using that while the phone is unplugged, the cpu frequency and screen brightness are very heavily regulated (cannot run @ 1.5 or full brightness even while phone is cool; goes away when the phone is plugged in). Please do not start telling me that 100% brightness is as unnecessary as 100% cpu frequency (I dont ever use 100%). I think you and I will just disagree on acceptable limitations of capabilities, even if I agree with you that they dont affect normal phone use at all. I see it as a mystery that needs solving.
And I am glad to hear that your phone works so well with the official rom . I could wait for official JB on the e973 but I'm impatient and Houstonn did a great job with the port.

So your phone's service menu doesnt have the High Temperature Property and the Thermal Daemon disable buttons?
You still can ask someone to disassemble korean version service menu to find the flags so you can use it on E973

[Q] Issues on my galaxy nexus.

Well i'm having issues with this phone. it's getting hot when browsing and even facebook, like 60+ Degrees. Games get even hotter. but it's getting real cold quickly. And getting hot means Drains battery real quick. i get -10% of battery by playing a game for like, 5-10 mins.
is this an issue on 4.2.2? Because i haven't got this issue since i got into 4.2.2
i'm currently on Paranoid android 3.50 and fancy kernel r24. no extra settings.
Baseband is UGLL1 if that's necessary.
This is my first thread btw. i'm sorry if there's some mistakes or something if there's another info you need tell me .

Question. Why does my s4 keep overlooking itself?

I have a S4 mini running custom carbon kk unofficial 4.4.3 as it comes with the settings to set CPU's and governors but the phone keeps changing the min to around 1400 but the max stays at 1700.i don't notice until my battery is draining really fast or gets hot. anyone kno a fix to this?

Which governor is it using to set a min of 1400? Ever likely it gets hot and eats power! I use f4k's kernel, and the 'Performance Control' app to look at and alter stuff - you don't say what you use or have tried.
There is a Carbon 4.4.4 available with f4ktion 1.5 kernel - might be an idea to flash that and the problem might go away!

It's on every governor this happens but I use Wheatley. I would manually set it to around the 300s but in a couple of hours it would auto set at 1400 on its on. This causes my battery to drain my kernel version is 3.4.91 f4ktion 1.4.5 eur lte

Strangely enough I've settled with Wheatley too! but it spends most of its time at 162 when not in deep sleep (a bit like me!). This really needs posting in the Carbon thread so I would post a few more things here to help or comment on stuff to get to 10 posts and then ask in there. I can't think what could be causing that behaviour, if it was me it would be bye bye 4.4.3 and hello 4.4.4

Does the actual minimum change rather than it simply running continually at 1400+ and if so which governor does it change to if any!
I read somewhere in the Carbon thread someone was having similar problems so they flashed the kernel twice, one directly after the other; seems something wasn't getting written correctly the first time but was the second, and the problem went away. Worth a go...

I found this : Q: CPU/GPU frequency doesn't stick?
A: If your frequency settings don’t stick, it's because on certain Qualcomm or JB and higher devices, there are certain system services (thermald/mpdecision/project butter) or kernel feature that rewrite frequency settings based on current thermal status and/or touch input. Certain custom kernels for your device should include work around for these issues.
Is this a fix?

It could help. Trickster is good. However, this suggests that there is something else causing or forcing the frequency setting to be changed. The question is what? and I've no idea:crying:

Haha I found the problem it was either this battery saver app or I changed to scheduler to anything besides row

Thats good. It was probably the battery saver because they usually do the opposite!

Benchmark problems

So just today, I realized I was under clocking my phone's CPU at 1920 mHz instead of the base clock speed of 2150 mHz which basically meant I was limiting its performance. Realizing this, I called myself an idiot and was also excited to see my benchmarks at base clock since its 165K using antutu when under clocked. So I changed my clock speed back to 2150 mHz and started benchmarking. All was going well until around 80% of the benchmark when the screen just instantly turned off and the notification light dimly lit up, no warnings, just instant. I can't interact with my phone until I forced restart it. I under clocked my phone again if it still has the same issue but benchmarking worked out just fine. Any idea why this happened and is there any fix? I really want to know my benchmarks at 2150 mHz ;-;
Ps: idk how to call website admins but please tell them to fix their website for PCs, can't even login since text boxes are missing, can't make a new thread since title input text box is missing when making new thread. Everything is fine on phone tho.

Im using nameless kernel. I now just remember having this same problem before and rebooting doesn't work, and i also remember that this problem is the reason why i underclocked my phone. The only thing that caused a kernel panic so far is antutu, probably geekbench too but i can't properly remember.

Is Redmi note 8 pro locked at 2 GHz normal?

i've been using this phone for about 2 years now and recently moved (about a few months ago) to using a custom rom (crdroid 7.1.2). it was running smooth and cool until day the clockspeed decided to lock itself at 2000 MHz (checked using cpu-z). I do not know if this is normal but the phone's temperature goes up to 36C on idle. i thought the problem was with the Lspeed app (+custom kernel) so i uninstalled it but it didn't work. I also factory resetting it, but still not luck. will updating the firmware resolve my issue? if not, what other available solutions are there?

have you thought about flashing the stock kernel ?

If you are using Fast Charging, that heating is entirely normal (happens to me too)
But heating during idle is not normal. Try changing CPU governor to something else. (like schedutil or powersave)

Do you know how to change cpu governor? I tried doing it last night but didn't find a whole lot of information. Schedutil seems to just set it all the way to 2ghz, so I want to change it to powersave

use Rootify, select the CPU tab located at the top then change it.
The app sometimes gets stuck at Loading screen though.

ok so it does work when i change the cpu govenor, but the only option that actually works is 'powersave' (as well as 'userspace'). all the other ones still sets it to 2GHz. 'userspace' seems to have a somewhat of an improvement but it's only setting everything to a constant value. is there a way have it set to balanced mode?

powersave forces the processor to work in the lowest frequency availible, thus consuming less power.
userspace allows the app to set the CPU frequency whatever it wants. This isn't supposed to be used in Android since changing CPU speed thorough an app is super uncommon.
Others like ondemand normally keep the power low but starts using the higher frequencies if a processor intensive app is launched.
You can learn which governors do what in this post so you can set the most suitable one for you.
