Power saving?

I tested to see if power saving reduces performance and it indeed does. Try doing a quadrant test while using power saving and then after and you'll see the difference.

If you use an app to monitor cpu usage you'll see it underclocks it to 1GHZ instead of 1.4GHZ (as a maximum)

Yes, this was known for awhile now. I lightly touched upon it from a review my topic. It does however increase the battery life by %20 to %25.

Don't use it myself but my brother tested it last week. He had over 3 days on battery with over 20% left.

That's nice, but what if you're 400 miles away from a gas station? It would be awesome if the "ferrari" had the ability to adjust its engine and fuel injectors to give it another 2 to 4 mpg.

Why would anyone even drive a ferrari outside of the city? Putting that many miles on it is useless

Omg, are you serious? Did you not understand it was an analogy? It doesn't hurt to have the option. If you're on a long plane ride, it's obviously beneficial to have such a feature.

I'm using power saving mode and it increases the battery life a lot. Games are running just fine and no slowdown at all. I don't care if I'm getting a lower score in some ****ty benchmarks I'm talking about real life usage.

What is a safe level to over clock?

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance
Cheers

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?

Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic

IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.

I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again
Cheers
Corey
Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?

I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app

I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.

Nexus 7 under clocking itself

It's called 'saving power'.
As long as it doesn't lag and clocks itself up to maximum when required, there's nothing to worry about.
Or you can get some CPU clock app and set it on maximum performance. But don't be surprised if you can boil eggs on it then and the battery dies in 2 hrs :good:

clear the data for tkt and reboot. if you are using tkt, you dont need a powerhal script, since tkt runs it automatically after opening it.

Does Tegra 3 really need overclocked? Having used Tegra 2 I can say that could definitely use a little bump but so far T3 is keeping up with me and I can see a big difference between T2 and T3. Makes me wonder what T4 Wayne has in store.

does it need it.. probably not. do we want to overclock anyways.. yes! btw, its underclocked by default(its rated to 1.5ghz). i use it at 1150mhz as a daily btw.

[Q] i9500 verylow benchmark and perfomance cpu float problem

hey my i9500 has very liw benchmark and hit only 19000 on antutu benchmark
im using phonix rom v4 plus presus v5 kernel
no overclocking has been perfomed and settings are set to their default
according to my screenshot from benchmark results, my cpu float point is lower than regular and I dont know why
plus ram memory hits very low score while I have only 0.9gb ram under use out of my 1.8gb

This is my benchmark using Omega v8 and latest perseus v5. All is well. Maybe your phone is too hot and cpu starting to throttling.

Sent from my GT-I9500 (Hassan Khalid Malik) using xda premium

you can use setcpu to monitor (set the min and max clock same as the one in stweaks) if you set e.g. 1700mhz at some point (if cpu start throttling) the clock will stuck at 1400mhz, or 1200mhz depending how hot is your phone, It simply can't avoided as far as I know, if you want to make a benchmark, cool down your phone first

As I already said, I had never ovrrclocked my device and never changed any settings.. cpu is set on 16000mhz as default. So I dont know what u want why using another applications

[DISCUSSION]Governors and Schelduers

Okay,so i made this thread so that development thread become less spammed with your questions.
Please,share your opinions here and ask questions,someone will answer you,and share your screenshots of battery life.
I personally use PegasusQ+VR,it gives great performance and good battery life.
My second choice would be Abyssplug+SIO,especcialy for the hotplug feature.
(In case you dont know what Hotplug is,its the feature that turns off the second core when your phone is not in use.)
I cant decide wich is better,tommorow ill test Hotplug+sio,and ill post screenshots of both tommorow.
Please,ask any questions here,dont spam Benz's threads.
Thank you

OnDemand + CFQ (Like in stock ROM) the only way that don´t dry my battery.

With that combination my phone is slow like hell..have you tried those that i wrote.

Hi, can you tell me the best combination of governors to use. I'm using latest cm
10.1 maclaw build with hotplug and noop, but i think CPU its not sleeping cause i loose about 5% battery in 2hours withought using my fone at all. Thanks
Sent from my GT-I8190 using xda app-developers app ?

Hotplug governor is indeed a joke, at least in Maclaw's CM (not surprised). There is no way to set it up for low battery drain /and/ reasonably smooth functionality. Right now I am using Ondemand + CFQ while playing with the powersave bias and up threshold parameters. The only thing I wish I had from Maclaw/Benz's kernel is the vr/sio schedulers.

You have VR and sio schelduer in Benz's kernel,and Abyssplug governor with real hotpulg feature,when you dont use the phone cpu shuts down one core and the remaining core runs on 200Mhz and 1% usage.

I would gladly use that kernel if it didn't have the dirty flickering fix. And if it didn't require CM10.1 reboot edition.
Also, when I was on CM i ran a logcat with hotplug activated. The second core would often reactivate even if the phone wasn't doing anything, with the screen turned off, then soon turn off and after a few seconds repeat the process. Maybe this phone really needs the core.

What flicketing fix? I got no flickering on the latest Maclaws cm and benzs kernel..and it shuts down the core,you can see with system monitor when your screen is on..dunno for screen off,but i get like 1% drained for a hour with screen off
Sent from my GT-I8190 using XDA Premium 4 mobile app

The 63 fps refresh rate, which "fixes" the UI flickering.
And yes, I saw the second core turning off myself. However, I am not sure if it keeps being off enough time.

Well in maclaws rom i dont have flickering,but in olivers i had. I dont know,i got decent battery life. Not good as stock,but its ok

And what exactly is so wrong with 63 fps refresh rate? Will your screen fry because of it? No it won't because it can't. Will your phone explode while being used? No it won't because it can't. What's the issue here then? Tell me.

Have you considered the battery drain implications? The battery is weak enough as it is, a higher than normal refresh rate only wastes more GPU power thus more battery.
