[Q] Setting clock speed to 800 -1200 mhz?

I know unrooted desire z devices always work at 800mhz. My device is set to 245mhz min and 1400mhz max (interactive or smartass governor). It sometimes causes my device to wake up a bit late. I wonder how long time my battery goes if I set my device at min 800 mhz and max 1200 or 1400 mhz... Did anyone try this clock speeds?

That's way too low of a min speed, just bump it up to the next (I think it's 386) and you should see noticable improvement.
I'd also suggest the ondemand gov; since it only ramps up to the top speed when needed, then drops it back down again, you should get a bit better battery life.

i read ondemand and conservative governors are od, so using interactive or smartass are better then using others. I will try min 368 mhz but am not sure if it works...

What are you trying to accomplish by messing with the clock speed? Leave it alone at default. Performance difference is NEGLIGIBLE (bottleneck is elsewhere), and all you'll accomplish is eating the battery and burning it up with excessive heat caused by excessive clock.

First of all, I would like to thank you for your comments.
People don't do anything to access root if they don't want to mess device. I am one of them and want to have a device which both has performance and visuality. You offered me to not to change clock speeds. But we know HTC Desire Z is scheduled to work at 800mhz everytime (default). My opinion is just to set minimum clock speed to 800 mhz or something like this. If my device was burn by this clock speed, it was already dead.
Today i tried this clock speed (min 614, max 1382) and during the day it didn't heat up. Moreover, 8 hours passed, i played NFS for about 1,5 hour, made some call and 30 percent of battery left. It seems this clockspeeds doesn't cause battery drain or i couldn't feel it...
EDIT: 13 hours passes, 16 percent battery left (I made minimum 30 minutes of call)

[Q] High Battery consumption?

Hello,
i hope you can help me.
I'm using MildWild 4.3 based on Oxygen 2.3.2 with Thalamus kernel.
When my desire is on stand-by modus, it consumes 1 % per 45-55 minutes. Because of that i'm very glad.
But when i use my desire, p.e when iuse play store without anything downloading it consumes 1 % per 2-4 minutes.
My question is: is that normal? Or must i change any settings or an another kernel etc???

Can nobody help me?
I don't know why you don't reply? This is my second thread, and the first thread I've not recieved any answers either.
Well, it is 18 hours past after unplugging my phone and I have 71 %. But I'm used my phone 15 minutes after unplugging.
Is there all right?

it seems maybe a little high. screen should be the biggest consumer of battery once you start using your phone.
however i don't know your screen brightness and age of battery.
in standby seems ok, you can use something like 'betterbatterystats' to double check no app is keeping it in partial wakelock.
inbuilt kernel, or stock thalamus kernel (in my sig) should be fine. personally i use inbuilt cpu settings ondemand 245 - 998MHz, no other apps needed, and i think battery use is fine.
for what it's worth, here's another response to another battery use query...

Yes ,Its normal

hi
in the android phone its normal battery usage , but for better test u can change CPU governor to smartassv2.
don't forget battery Consumption mostly depend on kind of Battery and thats Amper

thanks for the answers,
I'm using thalamus kernel, 2.6.35.14_r-stable.
Screen brightness is automatic and i've bought my battery 1-1,5 years ago, original desire battery.
I also have Better Bacttery Stats, by partial wakelocks i have since unplugged:
Activity Manager-Launch with 2m 6s and 318 counts.
Alarm Manager with 1m 7s and 1244 counts.
wifi with 10s and 501 counts
sleep broadcoast with 8s and 460 counts
and other programs.
Since unplugged: 10 h
deep spleep: 8h 7m
Awake: 1h 54m
Screen on: 1h 43m
KWL: 8m 20s
PWL: 6m 9s
İs there all right, and I don't know which programs are these.
and under cpu governor I don't have smartassv2, i have powersave, ondemand, performance. Min CPU frequency 245 MHz, max CPU frequency 998 MHz, and what is smartassv2?
And can you please explain in a bit simple English?
My English isn't good.

Can you post a screenshot of your battery usage graph?
I'm my case, almost all the power consuption comes from the screen (Never under 50%).. I have to use very low brightness if I want the battery life to last.
Best regards.

How i said, it drains by using my desire. On standby, its all right.

looks fine, you can see that there is no app keeping the phone awake for very long...max 2m 6s.
smartassV2 is another CPU governor. whether it is better than ondemand will require you to measure the drain for similar activities, though personally i don't think it's worth it.
screen is still meant to consume the most battery as long as you are using the phone, regardless of govenor. no change of rom/kernel/touch screen phone will change this fact.
i can suggest turning off auto brightness and using a lower manual one. have a widget to toggle between low and high when you need to (many in google play).

Thanks for the answer. It is possible, the Battery is defect or it doesn't function well because of his age? Is there an app which measure the battery if it is all right with the battery?

theres lots of battery apps in the market but they only really tell ya basic things, health, voltage, battery percent etc.

Well... I've seen things with the same rom, same kernel and different results... mainly due apps keeping the phone awake, but in your scenario is not that bad. I loose 3% overnight with CM 5 MW's version which is awesome, but once i start using my phone.. let me see. I've lost 10% with about 20 minutes of browsing and 20 minutes of gaming... I'm using ManU kernel which is pretty good with battery life, but not compatible with oxygen version of MildWild.
Do a Nandroid backup and try CM version, just to check the differences if you're up to it.
Also, flash ManU kernel afterwards
Let us know if you need help, you have a drain but not awfully bad. However 1% every couple of minutes seems a bit too much .

Well, i don't think that there is a ROM problem. Many people using this ROM have good results than me.
Nevertheless, i will try MW CM 5. After testing i will write here.
I think, there is a battery problem .

Even if it is, you're not spending money without ruling out software issues right?

I'm sorry, but unfortunately i didn' understand you what you mean
Well, i tested a lot of ROM's (MW, ICS Nikez Sandvold Oxy) and i've notice that there isn't a kernel or ROM problem, it's just battery problem.
My battery is still working, but it doesn't work well. I've bought the battery 1,5 years ago, and this is my second battery (genuine HTC battery).
I've also problems with my first battery.
I don't know, should i buy a new battery? If yes, which battery do yu suggest, genuine or another?
And i don't have any good experiences with HTC batteries. Perhaps i didn't use the batteries well.

Undervolting - good idea or not?

I'm wondering if anyone's undervolted and to what values.
I'm also wondering waht the deafult values are and if they change per kernel.
Is there a way to disable SetCPUs undervolting settings?
Has anyone improved battery life with profiles? On the Eris this was the only way to get usable battery life.

Or not. I gave up undervolting after I actually compared battery life at stock values vs undervolted (on my old phone, sgs4g) and discovered it does nothing for battery life.
Edit: undervolting "might" marginally increase standby battery life, but considering how good this phone already does... it certainly won't increase actual screen on usage.

Depends how low you under volt. Got more battery life, maybe about an hour, after finding optimal battery life on my gfs Gnex.
If you don't under volt correctly, of course it won't improve battery life.
From my sexy white, Nocturnaled HTC One X

If you're not overly comfortable with undervolting, then using one of the many kernels with Smart Reflex will do a mild undervolt for you. If you are comfortable, then the only way to find numbers good for your phone is to try and test. I tweaked mine down to the point that I was occasionally getting hot boots when the screen was off and media was playing. Tweaking the numbers back up added the needed stability. Even little things like kernel or ROM revisions can change what voltage is or isn't stable. Another example is that when I updated my Jellybro CM10 version the other night, along with updating leankernel from 4.1.0exp3 to 4.2.0, I had to increase a few of my voltages to avoid hot boots.
Just for example numbers, here are mine:
Code:
1350MHz -- 1200mV
1200MHz -- 1150mV
920MHz -- 1050mV
700MHz -- 950mV
350MHz -- 825mV
These numbers will vary from device to device and even between ROM/kernel combinations, so don't use them as hard fact.

Thanks. On a phone like this it might not make a huge difference but on the Eris (Where stock battery life could sometimes be 6 hours if you actually used your phone) an undervolted kernel with setcpu could turn those 6 ours into 48.
Thanks Cilraaz, I'll try those voltages out and benchmark a bit to see if they're stable for my system.

Two things I can say for sure:
1. you will have very limit battery gain by undervolting with Gnex, no matter how low you try.
2. undervolting will bring some stable issue if you get too low, like lose signal and reboot.

I am using Kernel Franco GPU 384 Stock rom on my 4.1.1 and did undervolting
Current configuration:
384Mhz
950mv
------------
729Mhz
1050mv

1036mhz
1125mv

I did not change the frequencies of overclocking, because I'm not using them.
I felt an improvement in battery consumption unless the unit is heating up.

Just curious - what kind of profiles are you using? I have a "Screen off" that's 350min and 700max. I figure that's fast enough f someone calls me.

I've read many times undervolting isn't worth it.

I'm using the following with SetCPU: default (1350MHz-350MHz), charging, CPU temp > 64, and battery < 35%.
If you're using a kernel and governor that support hotplug, then you likely don't want to use a screen off profile. The combination of the two can tend to cause sleep-of-death or hot boots.

Most people don't want to spend the time to do it right.

I'm actually not used to the new kernels. I haven't messed with my eris in about a year and back them there was "smartass, on demand, performance," and some other one that clocked down instead of up
Can you explain th escreen off profile causing issues? I don't even know what hotplug is lol I've been out of Android for a long time.

Hotplug disables one of the CPU cores when the screen is off. Some governors, like hotplugx, will also attempt to disable a CPU core during periods of low CPU usage. For some reason, this combined with a screen off profile can cause some problems. I assume it's because of the "screen-off-max-freq" that Imoseyon mentions in the quote below.
Personally, I prefer the interactivex governor with leankernel by Imoseyon. From his kernel thread:
With interactiveX V2 (for gnexus), things are a bit different, since gnexus has built-in support for screen-off-max-freq for all its governors. I took the new interactive code in gnexus, added early_suspend support (screen off/on trigger), and then added logic to the code so the governor uses the phone's built-in hotplugging capability to turn off cpu1 when screen is off (and then turn it back on when screen comes back on). Cpu1 goes offline entirely - no idle, no sleep.

I think undervolting helps - my phone is running 728 - 1228 using the interactive governor, with voltages of 600 mV, 700 mV, and 800 mV (728 MHz, 1036 MHz, 1228 MHz respectively) and I haven't had any issues so far. I know there are some reports that say undervolting doesn't help much, but those are when people undervolt by like 50 mV, whereas here I'm going like 400 mV under lol. (Yes, smart reflex is off).

Thanks Cilraaz. Good to know.
So turning the screen-off profile could improve things? Honestly, my system does fine at 350mhz with screen off. Turning a core entirely off would probably help though.
If I use hotplugx governor that would disable one core when the screens off, right?

Hotplugx will disable a core when the screen is off or when there is low system load. Depending on your kernel/governor choice, other governors may do it also. On leankernel, for instance, interactivex will disable a core when the screen is off, but not on low system load.

Ok, thank you.
I haven't done any comparisons of before/ after since I undervolted/ underclocked first thing. But I was browsing for hours while listening to music while talking to a friend with GTalk. talked for about 1.5 hours with someone, Left it on overnight (10 hours), woke up, used it to talk (voice to text) to someone via GTalk, and it's 3:25PM right now and I still have a fair amount of battery life left.
I'd heard mixed things about the battery on this so I'm happy.
My voltages:
1650: 1300
1520: 1250
1350: 1175:
1200: 1125
920: 1000
700: 925
350: 900
I stress tested each one without a crash.

Battery help for those having issues

I do the following to get my phone to last a full day and sometimes more i use battery guru as well as advanced task kill i have auto kill on in advanced task killer and have it set to aggressive every 30 minutes to kill all background tasks. make sure in battery guru u have low power mode on. greenify also saves huge amounts of battery but root is required. also my fave app i use is android tuner i change my cpu governors to on demand and have all four cores running at GHz this saves the most battery i have noticed and my phone never over heats ever good luck to those out there

I have big problems with Battery Overheating.
I'll try and report back

So, what you're basically saying is you're aggressively patrolling your tasks, and reducing the cpu speed down to 1ghz max?
How responsive does your phone stay after reducing your speed?

My phone is the same because I have all four cores of the cpu running at a max of 1ghz ondemand for the governor of each core. this enables less overheating and easier multitasking with all four cores running and less demand on the other cores so the cpu is also able to last longer cause no cores will burn out as fast as say having only one or two cores of the cpu running because the phone doesnt get as hot as it does with less cores running. so I get a huge improvement in the responsiveness because of this phone has never gone over 35 degrees celcius since ive been doing all this

Question A52s: CPU cores 1-4 always max

Hello. Is it normal that the cores 1-4 are always at maximum frequency? This is only the case, when the screen is on. The phone goes into deep sleep when it's off. Cores 5-8 are at dynamic speed as I would assume it. Could please anybody check this with CPU-Z on A52s? Betterbatterystats doesnt see the cores 5-8 (I assume), so it always shows only the frequencies "deep sleep" and 1804 to me.
Thank you !

If your screen on battery time is normal I would not worry about it.

1800 MHz is not max. Cores 1 to 4 (0 to 3) have a max of 2400 MHz so at 1800 they are only half asleep as expected so to be able to respond quickly when needed.
I have the same and have excellent battery time and screen on time.

No, 2400 is the max. of cores 5-8 and is at dynamic speed and reaches sometimes 2400. Cores 1-4 should also be at dynamic speed with max. 1804. Could you please send a screenshot of your CPU frequencies? Do they also stuck at 1804? This really drains my battery more than normal, when the screen is on. With lower frequencies I get better SOT. BTW, the overlay app CPU Float is great for tracking the CPU frequency of all 8 cores.
Edit:
1.Screenshot: most times my freqs are at this. 2nd: with some activities these are the values. Sometimes after reboot all cores are at 691 but at some point (could be a minute or an hour) first 4 cores max out with stucking there and never returning back to 691. 3rd: difference can be easily seen in battery statistics. It's both screen on at the mentioned point, but battery gets drained. I have now reported this to Samsung.

If CPU-Z is running my four first cores are at 1804. I am happy with this, and I have as I said no problem with this. If you want the save battery you should consider using a power saving setting.
I have very good battery time and plenty of SOT!
