Overclock VIVA occasionally. Can we ?

Subject says it all, 200MHZ sometimes doesn't cut in, if we need the speed, what is the best app out there ?
Thanks in advance

Found the solution...
Thanks for looking at the thread ... It was shinny isn't it.

Don't waste your time, PPC CPU can't be overclocked

No?!?! look this!

You really need to do some research my friend.
Alright, let me save your time. Just search for Omapclockkeep, you'll clear your old taboo.

Just for the information, i have happily cruised my VIVA's CPU at 250MHZ, battery life is ok, not much affected.
Battery lasts 2 days with occasional WIFI plus Bluetooth.

3 apps
I've seen 3 apps so far that promisses the posibility to OC ppc...

and pocket hack master even says it can prolong battery life (they also have another app called Pocket Battery Analyzer that seems good)
Anyone tried the apps? do they really work?

I am using Omap keep cause you can keep the default speed at ideal and as soon as you start using it, you can set the speed like 250 and gain the extra performance through overclocking...

I'm using Homescreen++, which has a great overclock utility called CPU Scaler. It dynamically overclocks the CPU when the phone actually requires it, therefore saving lots of battery life. It also reduces the speed when it's idle to save even more. You just give it a min, max and boost value(when apps are really demanding) and it does the rest. It also monitors power consumption(maH, mW) and CPU temp. Good stuff.

I have used it and my personal experience of using PPC for last 5 years says anything that monitors eat battery...

[Q] dynamic overclocking

.
..

I use setcpu to do this.
Look into the governors, choose one.
Then choose the appropriate thresholds (in the advanced menu) for what you do.
It doesn't allow you to tweak per app, but tells the cpu governor at what %of cpu to move to the next cpu speed (up or down).
I set mine very low, as i care more about battery than performance. So my up threshold is like 95% or something.
But my down threshold is a lot more agressive.
But you do the opposite.

Hello,
my question is regarding dynamic overclocking. I've used the ones that raise the speed when under a load - but my question is -
Is there a way to return to stock clocks after certain time?
Explanation:
situation1: I want to check new single mail or open new single IM or check university's website for some news, I want the device to be FAST as possible, nevermind the battery.
situation2: I want to use maps/navigation/IM/games/web browsing for longer period of time (hours?) with the screen on. I don't need all the power when I play solitaire, text on IM or browse not-so-important news websites.
I think when I've seen the realtime clock displayed on my phone it jumped to max clock right after I've clicked almost anything on the screen. I want the speed-up, but after certain period of time to stop doing this in favor of the battery life-time.
Any ideas how to do this? Thanks!

Yes, just throttle the cpu to give you more power when you are sluggish. That could work for you.
Me? I have my droid do 110 when screen is off (works quite well!), and then I FORCE the unit to 1000 when plugged in. Besides that i throttle the cpu based on battery power: more cpu power with more battery life. Makes my droid last longer.
I might want to add a throttle up when sluggish and not in my personal battery red zone and a throttle down when the cpu gets too hot period.
Any cpu frequencies that you all would suggest?

MuF123 said:
Thanks for the reply, but - think about this, I will start a 3D game, it will use 100% of the cpu so it would always stay at the highest possible frequency (+highest voltage). I don't want that.

I dont get it?
You dont want max speed in game? Why do you overclock?
If the game requires 100%, the it will (and should) clock up.
As soon as the game doesnt, it will clock down (depends on your threshold).
The only other i could see, is to change the max clock rate in setcpu before you play the game. This will ensure it doesnt clock higher than your choice, but requires a manual step.
But seriously, if your cpu is pegged at 100, why would you not want it to step up the higher speed?

MuF123 said:
exactly - I don't want minimum battery in game, that's why I don't want to overclock.
actually from the nature of 3d rendering I think every game will run at 100%, but the situation when the game hits the frame limiter (not likely on milestone).
I want snappy performance while doing few quick tasks:
e.g.: new IM comes, I want to unlock, load the application, get to the IM, reply, lock. (40seconds)
or
taking phone from cradle - I want the phone to load homescreen fast, rotate the screen, open phone app, to look at last missed call and call back (20seconds).
Battery life won't be affected by 40 or 20seconds of ~1100mhz, okay.
And then I start a game for a prolonged time. It will run smoothly even on 550MHz, the additional frames I see are just waste of battery = I don't want that.
So now I have two options - either run at max speed and it will be always fast and it will drain my battery when I decide to play for an hour.
OR
I can use default speeds for longer battery life for everything and I will wait an hour to rotate the screen in browser or IM app.

You could compromise and find a max speed that you could undervolt to make it drain battery like stock. My 800mhz vsel is less than the default vsel @550. So the battery drain is less...
It requires some trial and error, but most "slight" overclocks (700,800; depends on the phone) can be configured to drain less than stock.
Of course, if you feel you need 1000 or 1100, this wont work as it requires increasing the vsel (or at least not decreasing it).

[Q] Nexus 6 problems: display, battery

I've received Nexus 6 from FlipKart, Its great but two major concerns:
1. Screen is very yellow (warm color) and on reducing brightness it becomes magenta. When compared to any other phone including Nexus 5, its extremely yellow. Tried couple of apps, none of them do a good job of fixing the yellows. Did anyone find a good app/setting to calibrate this screen right?
2. Battery life is pathetic: From 100% to 10% in half day. SOT is barely 3 - 3.5 hours (Greenified Facebook, Encryption off), no gaming, where as my friend gets 5hours. Sometimes phone hangs and switches off. When I switch on, it looses 15% battery. It has only been charged 2-3 times (only got it 2 days ago). Does it get better with time? or Am I having a faulty battery?
Update: forgot to mention my phone shuts down at 28% battery. And it didn't boot at all. I realized battery was zero. Is this calibration issue? Or bad battery

Flash elementalx, you'll be able to change color values and battery life is great

1. You can change your RGB using any kernel with support to it. Almost every single kernel have support to RGB LCD KCAL. Use a app such as Trickster to modify the RGB once you flashed a kernel of your choosing.
2. Battery life is subjective to how you use your device. Just because someone was able to achieve 5 hours+ SOT doesn't mean you will either because there are way too many factors that play into effect such as: cellular signal strength, wakelocks, apps installed, etc. If you want to maximize your battery life, look into underclocking the CPU/GPU frequency and flash a custom kernel (e.g. Franco) that removes mpdecision. Mpdecision is a huge battery drain and the frequencies that it selects is completely random and unnecessary in my opinion.

I agree that mpdecision really does drain battery a lot. I have mine OVERCLOCKED to 2.88 ghz with sensei kernel and intelliplug. And I am still getting way better battery life than stock. Just flash this kernel with intelliplug and there goes your battery issues. And you can also adjust your screen colors.

For more elaboration on mpdecision,
All Qualcomm based phones have Qualcomm prorprietary userspace binary called "mpdecision" aka m(ake)p(oor)decision. Instead of letting the kernel itself to decide what frequencies and how many cores to run, this "mpdecsion" binary polls the kernel run queue statistics and decides for the whole system the "optimal" frequency and the "optimal" number of cores to use. The concept is fine, except the decision making is done in userspace and it's 100% closed source so there's no way to tweak it and there's a latency (because all userspace binaries needs to "poll" the kernel for the latest information which is slightly delayed). - faux123

In other words, mpdecision makes your phone sit at 1.5GHz for doing the most simplest tasks, even composing a email it'll bring your frequency to be at 1.5GHz.
Download CPU Spy and use your phone, then look at CPU Spy and you'll see how much time is spent in that frequency. Then flash another kernel that does not use mpdecision then you'll see the difference, the phone sits at frequencies that makes sense for the load that is on the device.
The alternative solutions would be, Franco's Hotplugging Algorithm or intelliplug by Faux.

Battery life is very subjective.
I am still 100% stock, encrypted, auto brightness and get over 6 hours SOT every charge. Mainly WiFi, some LTE. No gaming.
I will root and switch to another kernel when I have time and see the difference. I would expect more battery.
However if you are only at 2.5 hours SOT on a full charge, I wouldn't expect it to double just by changing kernels.

Thats so impossible. I've switched to 2G only but i run on Wifi all time and yet 1 day standby and 3.5hrs SOT.

Impressive! I'm trying ElementalX kernel right now. Is it safe to switch-off MP-decision on that using trickster or shall I go with franco blind folded.

Well, not impossible as it has been that way on my phone since day 1.
But i agree that it is really odd how some people are getting 3 hours and others getting 6.
I had the opposite on my Note 4 though. Everyone got 6 and I got 4. So who knows?

You only want to disable MPDecision if theres a alternative. For Franco, mpdecision is 100% removed so you don't need to disable anything.
I don't know ElementalX so I can't say, ask in their thread. If you use Franco, everything is done for you and you don't need to do anything on your part.

My battery life with LK is pretty good as well! I was able to tether for 10 hours straight and still had 22% left after sleeping ~8 hours.

Setting the right CPU maximal/minimum frequency for better battery life

I'm totally a rookie for modify the kernel, but i wish to get better battery life for my nexus 6. So i read often that changing the CPU Maximal/Minimum Frequency - for example for the franco.kernel or Lean Kernel or other kernel - almost everybody get a better battery life and no wake locks. At the moment i use the nexus 6 stock with no custom software, but the battery life isn't very good.
My questions now: How can i setting the right CPU Maximal/Minimum Frequency for the franco.kernel or Lean Kernel or other Custom Kernel? Are there specific apps? And the most important question: Which are the right numbers to set for the CPU Frequency?
Thanks. :good:

first off, questions go into the q&a/help threads, not general. and there are many cpu control apps to use, some free, some paid. thats the way for you to setup your cpu anyways you feel like. and there is no such thing as the right numbers, you need to find the right numbets for your use. me, i overclock to 3033mhz, and still see 5.5-6.5 hours of sot.

Thank you!

You shouldn't necessarily change the minimum and maximum frequencies because they won't necessarily save you battery.
When you look at the mex frequency of 2650 MHz, that's how many clock cycles there are per second. 2,650,000.
Every task you do on your phone will complete within an amount of clock cycles. Let's make some things up to illustrate this. Let's pretend that it takes Facebook app 5,000, 000 clock cycles to open. That means it would take nearly 2 seconds. If you set your Mac CPU frequency to half of stock, that app is going to take twice the time to open. The question is, will running running at 1267 MHz for 4 seconds use less energy than 2650 MHz for 2 seconds?
Looking at the voltage table for elementalx, the stock voltages are 890mV and 1110mV so it seems to me that since the voltage for half the max frequency is a lot higher than half the voltage of max frequency, running a task for twice as long would use more energy than max.
Surely, there will be tasks that take significantly fewer cycles than max frequency, so in those instances it may seem a bit more balanced, but its one of those things you're going to have to just try for yourself. Some people seem to get better battery though personally I'm not tempted.

Thank you, too! Now i understand.
Should I flash only the Lean Kernel or franco.Kernel and then look again at the battery life? Is this enough to get a better battery life on my device?

no. kernels generally wont give you better battery life, but they can help you. battery life is dependent on how you use your device, how you set up your device, what apps you installed and use, your brightness, and the quality of your phone/data connection. and much more other things that weigh in less then these on nattery life.
some apps you install can be badly written, and take lots of battery, even though you rarely use. dropping brightness can increase your battery life. i keep my brightness below 15% usually. if i raise it to 35-40%, ill see a whole hour less screen on time.

What are your CPU Settings?

Hey, was just wondering what settings you all have under Kernel Auditor in order to ensure 5 hours+ SOT. I personally have a dual core setup and have the other two cores kick in when the load gets to 90%, but this seems sort of sluggish now and I only get about 3.5-4 hours SOT and I don't play any games; just simple browsing and productivity. Others manage to get up to 5-6 hours SOT and I wonder how, I have NEVER been able to get this much. Standby is great though, 10 hours overnight and I lose only 3% battery. I am running on Pure Nexus Project ROM and latest Hells Core Kernel.

thats about the regular time I get outa mine. If I had to guess a lot of these 5+ hours are from watching videos or something that doesn't involve touching the screen. I've been using HC kernel with just zen decision on max performance settings and gpu on performance governor (since it idles 27mhz anyway might as well ramp up to full 600mhz for touches) for smoothness.

I have it setup that all my cores are on all the time, no hotplugging. ondemand/deadline, mpdecision disabled, fsync disabled. and I get 5+ hours sot every single day. no, I do not watch videos. but I do keep my brightness all the way down.

Hey, where do you go to disable fsync

it has to be an option in the kernel that youre using, at least the kernel has to expose it so that you can disable it. if its not xposed in general, then you cant disable it. im using despair kernel.

Try undervolting. Unless you severely under clock your cores you won't really see battery life improvement.
I keep my max CPU speed at 2803mhz. You might think "oh well if you're running higher frequencies then more battery drain". Not exactly. The difference between 2649mhz and 2803mhz will be negligible in terms of battery life so I'm seeing a slight performance increase with no significant battery loss. For example, on 2649mhz after a full day of normal usage I'd have about 49% battery life. On 2803mhz I'd have about 43%. I got a good performance increase and a more snappier device in terms of loading web pages, apps, opening documents etc so that extra 6% I lost doesn't matter to me, because its not significantly impacting me, I barely notice most of the time.
So yeah, the same goes for lowering CPU speeds to unless you significantly lower them. Putting max CPU speed to something like 2572mhz, you wouldn't even notice e the difference in battery. Now lowering it to like 1958mhz, or 2188mhz and you'll see a difference because at that point your severely under clocking.
You could also be draining your battery by hotplugging. That's why some people like Zen and MP Decision to keep all cores online when screen is on. If you use your device often, its better to have all cores running. If you don't and its kept in your pocket for hours at a time, hotplugging is the way to go.
Try under volting too. I do. Global Under Volt of -60.

undervolting doesnt really save you battery, but it does reduce heat. and hotplugging or having all your cores on doesnt really factor in when you dont use your device that much. as, if you have all your cores on or hotplugging, your phone should be in deep sleep anyways. it does make a difference when your phone is awake. i get much better battery life when all my cores are on all the time.

Should there be a sticky of suggested settings of differing requirements of speed, battery life, etc?

honestly, I don't think so. as the settings/setup used is always dependent on how you actually use the device. and many people have different opinions on how it should be set up.
