What exactly happens when the energy saving mode is enabled?
I know in the settings it tells you some points, like display freq, brightness, haptic feedback, but how far is the CPU getting underclocked exactly?
800mhz

How does the phone perform? The us model specifically. Does it seem to slow down a bunch?
800mhz is international. Maybe us is different. No idea how either perform

Yeah it is noticeably slower on some Apps, and even on Opera mini when I'm going back and forward through loaded pages it looks easily a third slower, but going through the phone menus and system internet browser seems about the same.
Thank you! Does it use all cores at ~800Mhz or just one or two?
I'm on power saving all the time (int version) and no slowdown for me, even when gaming, and it seems to save a lot of battery, the only slowdown is sometimes on wake-up when I swing to unlock it like slowmo waves on the screen but it is not happening every time (only when sleeping for a long time).
I live in SA and when i ran a benchmark, i was running at 1ghz on pwr saving

I did a simple test. I use set cpu. When I open set cpu and touch the screen and move my finger around, the CPU will ramp up to 1700Mhz (Overclocked).
I then set power saving mode on and tested it and it wouldnt surpass 800Mhz.
I tested this as although I had read it was 800Mhz, I wasn't sure so I tested it for myself and it yielded the same results.
It's hard to perceive that it's running slower, but benchmarks are very low in power saving mode. According to Quadrant, it runs at 1Ghz in Power Save Mode.

I just tried to play N64oid on power saving mode and it's really slow, so yeah for really demanding apps you'll see a differences but for normal games / apps there is no problem at all.

Howdy all..
I have a couple of questions about battery usage relating to screen power consumption.
First some background on the.phone
Aussie i9100t
Cm7.1 with its base kernel (wolverine)
Stock radio kf2
Now, if j sit down and read tapatalk or Facebook for 15 minutes ill burn 5% battery (even with the new Samsung 2000mah battery I just bought)
I have the brightness set to manual and as low as it will go, it actually seems way too. Right for minimum settings to be honest.
Just wondering if anyone has some suggestions on where too look for issues
Edit, just a note, I've had 2x i9100's prior to this model and I'm pretty positive they weren't this bad
Cheers
Kyle
Try a different radio, if your browsing on 3g....if on wifi try a different kernel like siyah
Thanks for the reply.
I gave siyah a go yesterday for 12 hours but found a similar result with the stock battery.
Dunno hey, just find it quite strange that the last 2 sgs2s I've had were not like this..
Couple of screenshots..

Thanks for that mate, do you find lag when scrolling with siyah? I got it a bit, maybe selected the wrong governor or something ...

Nope.. I use setcpu for uv and oc and used tegrak oc app to uv gpu and change governor to cfq which i believe is better (in my opinion)

Im using SiyahKernal and I'm curious about undervolting.
I want a safe/ok combo that will be smoothish and fastish but good for battery.
I'm currently running the cpu at 900mhz using extweaks.
Any suggestions? what're your settings?
Undervolting takes time and patience.
Start with -25 first and test if it is stable for a day or two.
If it is, move on to the next step.
Personally I didn't undervolt yet because it seemed to lower my average benchmark scores. Overclocked to 1704 and get 63k average in quadrant!!! (Not that it really matters in daily use...)
Yes do it in steps. The only danger is too low a voltage will cause a reboot when idle if theres not enough power to keep going.
I got mine to -100 for every step, stable. This means Samsung were generous with their voltages IMHO, but OEM's generally are. HTC are the same.

Thats amazing! how was your battery?
So the only danger is a reboot? no damage? apart from the obvious loss of work unsaved or game etc.
Not really bothered about benchmarking. just battery life with at least an 'ok' performance. i can easily set it up later when i need performance.
Just really love this phone and am mosty working all day.
Not really for undervolting. Its over volting that causes damage. Battery is ok. Not amazingly better. Cell Standby is killing me.

yeah cell standby is a big hog. it drains more than 45% of my battery every charge

So I open an app like the play store or chrome in the screenshots and get 100% load for 10 seconds or more. I noticed this behavior on different roms and kernels/governors.

That's only 51% maxed out would be BOTH CPUs at 100% so really your concern is?

Because it's a waste of energy.
reborn90, sorry for the off topic question but what are those system widgets (CPU, Disk I/O .. etc)?
Perfmon its the app

Without accounting for exactly what the CPU is doing you really can't make this assertion.
Me neither, that's why I ask. It just looks buggy when the cpu starts scaling to max frequency (for a long time) because a new app is started.

Try a different governor, or maybe increase/decrease the refresh rate of your resource monitor? (BTW, scaling to max speed on load is actually better for battery life in some cases, as the task energy required can be sometimes be lower when you burn more juice but complete a given task in a shorter period of time).
The cpu (core) load shoud be independent from the governor, apart from the current frequency of course. I still have the feeling that it is some kind of "phantom load" but actually I have no idea. I switched from an ASOP rom to CM10.1 and I haven't seen the problem yet. :fingers-crossed:

Its true that load wouldnt be caused by the governor, but the governor you run does affect how load is handled and whether there averages more or less load on the system. By running at a higher speed the system load is decreased because the processor is going through its tasks much faster. If the governor is keeping the speed lower while doing a task then the system load will be much higher because the CPU cant complete things as fast. So load and governor are linked together, but it is the tasks being run that cause any of the load in the first place.
Since the problem hasnt come back since switching to CM10.1 it was probably something in the system that got bugged and caused this behavior.
Yes I agree, but in this particular case I have maximal frequency and core load. It's much better now with cm10.1. :good:
Hello friends,
I was feeling little wariness while I am holding my device in my hand and when I checked my device temperature with Cpu-z I got these readings. So please confirm is this really a concern for me or not.
Thanks

Woah buddy those are some heavy temperature readings there. I have not encountered any heating issue except while installing custom roms or using the phone while gaming in high brightness. I think the fact that you were using your phone while it was being charged increases the device's temperature greatly and caused the problem because even my device heats up like crazy.

These readings I noted after my phone booted up after 'optimizing apps....' but truly speaking I am feeling only little warmness.
While charging my phone temperature fluctuate between 45-50
This is my current temp reading while I am charging and typing this reply and I am feeling only little warmness[emoji14]
Is this reading normal or I have anything to worry about[emoji14]
Thanks
Sent from my ONE E1003 using Tapatalk
It is normal for the device to get warm when it reaches the optimizing apps screen because the brightness is set to max at default and processor is continually used. You have nothing to worry about mate.

Yup, it's pretty normal. Also it shows cpu temperature not your device's temperature. I can see that you have boeffla kernel installed, so be aware of modding too much with kernel settings. Thermal throttling is enabled in the kernel so no need to worry.

Mine is -100mv on blu.spark and Ashwin's CM13. Never had any problems with this voltage.

I'm always using - 100 undervolt.
Sent from my ONE E1003 using Tapatalk
I'm stable at - 95
-100 was unstable for my OPX
Working on Swell-V8... I'm quite happy with this setup
It depends on individual phone. Subjective
Here is my setup. Using Boeffla's kernel and his app. Also, with this uv profile there are no more overheatings. The phone stays quite cold even on gaming and stuff like that.
-75mV overall. 100 was a bit unstable, maybe 90 could work but this way I'm completely safe.
As I already said, I'm on -100, but I still have high heating... 55°c when playing Minecraft for 20 minutes.

Did you undervolt to an overall value or different for different frequency?In OOS, I had freezing even with - 25 mV.

How do you do that? Once i tried, hit one wrong voltage, and phone never booted to system.

Patience. You find the lowest for each in 25mv increments and from there tune them. It's tedious. Obviously if you enter a random voltage then it don't work. If you don't entirely unfetdtand PLEASE read up on it or you will fry your phone
Currently at -100 to -125mv on Boeffla. No fc's or reboots since I started using these voltages.
-100mV on BluSpark kernel, no freezes, no reboots.
If you use Kernel Auditor, "Boot on system start" gets activated several seconds after the phone has started, so you can revert any errors in normal cases.
I can go -60mV, no more on bluespark v128.
If i go more than -60mV, i get reboots sometimes after 12hours or after 2-3 days
