Probably all thought about battery drain issue. I have an idea how to fix it. In Lumia 610 processor is weak (800 MHz). So, I had the idea that if a processor driver from the 610 put in 710? The processor will not work quite the power and flow rate will be lower. What do you think about this?
All ideas are welcome!

It's a good thought but I am not sure that it can be done just by swapping out the drivers. The processor has to be underclocked for it to go down to 800mhz, and as MS has locked down the OS hard, we don't have access to the kernel for underclocking.
Skepticism aside , if this happens it will be a huge breakthrough. Totally excited for this and will follow the development.
The CPU won't be the main battery drain or even close, the Screen and the Wifi are the biggest drains
I have my tablet overclocked from 1GHz to 1.4GHz and battery drain is no higher than it is at 1GHz, the 710 CPU won't be running at 1.4GHz constantly anyway, it will clock down as often as it can
Screen by far is the biggest battery offender. Then, I'd say GPS, WiFi, Bluetooth, in that order, especially when any of these is in use. A CPU shouldn't only be underclocked, but also undervolted in order to get the most "gains", gains being a relative term here, cause you lose in performance.

Hi guys!For the last few days(that I have my Hero rooted that is) I'm using VillainRom 10 as my everyday ROM and have tried some others.Anyway,that's not the point!
Being one of the lucky ones whose Hero can happily overclock to 768 I came to use RaduG's extremekernel and ben39's no-bfs no-whining kernel.With the second,while configuring OverclockWidget I saw that it gives a 848MHz option with auto-detect frequencies.Is it possible?I'm not asking about stable daily use,but even for some minutes for benchmarking?Has anyone achieved it?Without making their phone catch on fire that is!
And secondly,why are we all using linux 2.6.29(for total newbies I mean the kernel) while there is 2.6.32-33-34?Can't a newer kernel be compiled for use with the Hero?Newer kernels would provide native ext4 support and would probably prove to be better overall.
Oh,forgot one more!I am currently running on minimum 176MHz-maximum 749MHz(after I got a couple reboots with 768 I abandoned 19MHz for stability) with screen on and minimum 123MHz-maximum 384MHz with screen off.Should I give it a higher minimum frequency?Sometimes it lags when waking up,the screen turns on but shows nothing but black and turns off again or it turns on and everything is distorted,colors are completely distorted,background is upside down and some other unnormal things,but everything is alright when turning the screen off and back on again.Does it have to do anything with the frequencies I am using?I am running on VillainRom 10.3.
Now I have set the minimums to 160 and 190 MHz to see what happens!
Thanks in advance!
About the high MHz... I have done it with over 800 but don't max it out at 848 or your phone will freeze but anything below works And that screen **** I've also had and it has something to do with the high MHz (don't know why) but it helped me to set the MHz lower when the phone sleeps in SetCPU And at last about the kernel... It runs on the old one on Android 2.1 but in 2.2 it will be upgraded to ....33 or ....32 don't remember which...

Thanks for your reply C0mpu13rFr34k!
I know Eclair is running on the old kernel.I just would like to know if it is possible to compile a newer kernel for it.
As for the frequencies...Are my settings alright?Some too high or too low?The way I see it there is a big gap between maximum and minimum frequencies when screen on which results on the CPU working at low frequencies most of the time,thus sacrificing performance.But it helps with battery life and presumably this and the screen-off underclocking reduce the overall damage caused to the CPU by the overclocking,which is said to reduce the CPU's total lifetime by 50% or more,depending on how much you overclock it.Working at 749 I sometimes get a nice 43 degrees Celsius while charging,but that's only when charging.Average temperatures are 30 for standby and 37 with screen on(average,can be lower or higher).
And one more question.At 800+ how hot does it get?Will it be stable for some minutes to do some basic benchmarking or nah..?
Thanks!

If your phone is stable your settings are just fine even though your phone might have problems waking up if the low freq is under 246MHz (something like that) Also if you want better performance you might want to test some other freqs and then benchmark... Sometimes it makes a BIG difference if your phone is running at 691MHz or 710MHz For me my phone works like **** if it runs at 749MHz but it works like a dream at 729MHz (I think the difference was 0.5-0.8MFLOPS) Im also pretty sure your temp is fine (OC shouldn't make your phone that much hotter since the voltages in all ROMs are adjustet). If you should compile a newer kernel you would first of all need a .32 (.33?) from HTC because of hardware capabilities and im sure there's is A LOT more things devs need to compile such a kernel but i don't know to much about kernels I don't really know that much about 800+ because I only did it once and benchmarked it (MFLOPS was **** and i couldn't get them high at all) actually it slowed down my phone but you should test it. Maybe your very lucky and your phone can take it
Well,I have set it to 653min-749max with screen on and 160min-352max with screen off.Testing only!But it runs like a dream if we don't take into account a small lagging when I turn the screen on and it has to change frequencies!But it's great so far.Will see how battery life goes!By the way,tried 800,806 and 848MHz,but none worked.It didn't crash or something,it just wouldn't change to it and stayed at lower frequencies(low as 246).
Thanks for your time anyway!
And a small question...How bad does overclocking affect the CPU's life?I asked around and was told that the maximum overclock for desktop PCs is 20-25%,depending on the CPU,while needing special cooling systems,and that it can reduce the CPU's life up to 50%.Given that we overclock over 40%,how bad do we damage our CPUs?

I haven't heard to much about that actually but from what I've heard it shouldn't damage the CPU at all because of the voltage adjustments but i find that very hard to believe... Talking from personal experience my phone runs as smooth now as it did when i bought it so my CPU has probably taken minamal- or no damage at all and I got it when it had just come out here in Denmark (Europe) which is about 8+ months i think? So I wouldn't care to much about the lifetime since It's probably like 1-2 years and by that time I don't think people are using the Hero anymore Keep up the good work with optimizing and your welcome

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".

Hi there,
I have searched the forum for a suitable answer but couldn't really find one.
after experimenting with different kernels and underclocking I have always wondered what the pro's and con's are for using 100 Mhz as lowest frequency.

Really 100mhz is useless, it uses the same voltages as 200mhz (so uses same amount of power as 200mhz) and you get a lot less performance. Also, from what it have seen I can be unstable for quite a few people. I really can't see any pros to 100mhz. I would recommend you don't use it. So you are using the same amount of energy for less performance and less stability. Hope this helps you
will give you 10 to 30 mins of additional battery life if you configure it properly.
Try siyah kernel and follow the guides in general section
I have a question related to this topic. I know that overclocking can reduce CPU life, but what effect does underclocking? Same CPU life? Maybe it increases the battery life but reduces the CPU life due to CPU not working in the native way?
Haven't found an answer for this yet. It would be useful to know about it since replacing a battery is way more easier and cheaper than anything you could do if CPU dies.
Edit: I'm refering to general underclocking (max and min frequencies, not only the min frequency).

underclocking wont affect the life of your cpu. the least underclock value will only be used when your mobile is almost idle or doing low intensity tasks, it will switch to higher frequency as needed by the task.
Hi Guys,
I am a noob here. I have never used a android phone before, not even a iPhone - so basically no smart phones.My first smart/android phone would be Nexus 4 which would be coming tomorrow.
I have been reading threads to understand andriod architecture and believe have understood to certain extent.
I have a question in clocking the CPUs and Voting.
As I understand, we have 3 states -Max, Min and Sleep for a single CPU core
Max - The frequency (clock speed) which CPU executes or maximum speed which CPU sends signals to its components and get the response back. This would be used when the system is on - which means when user is doing some process.. like texting, video chat, gaming (this case GPU is also involved) etc.
Min - This would be for background process when the user/phone is idle - that when screen is off (eq - gmail sync, facebook sync etc..)
Sleep - Screen off and no background process , the core will be in sleep.
And the battery level will be directly propotional to speed of CPU with respect to the volting.
Now lets say there is a single core processor in a phone which can clock upto 1.5GZ. and the stock kernel comes up with Max - 1.3GZ and MIN -0.5 GHZ.
Question is abt overclocking minimum frequency
1. why not overclock the Mn frequency to 1.3Ghz? because the backgroundprocess would be fast and phone/core will be sleeping after that,
which means process consumes more battery at that particular time but overall baterry should be efficient as there would be more sleeping time.
2. About volting, so far I have not seen min and max volting. So is there only one voltage/power drawn for max and min CPU speeds by CPU?
Please correct me if any of my statements is wrong.
Appreciate your help,
Thanks,
Franklin B.
Overclocking the minimum frequency to 1.3ghz would probably decrease your processor's life if you use your phone too much but I have been actually increasing my phone even 200mhz more than it was in stock ROMs, i've been using my device for more than 2 years and it still works perfectly. Finally, it all depends on how much your phone is good.
I also decreased the cpu min and max frequency when phone sleeps to 256 mhz which decreased a lot battery consumption.
Hope i helped !
Don't forget the THANKS button
1.you can but your battery life will be drastically reduced! There is a good amount of time after the screen is off and before the phone sleeps! So if over clock the min to 1.3Ghz, the processor will be running at 1.3Ghz till it goes to sleep! But if that's what you want you can do that!
2 . I'm not so sure about this topic either but I think the processor operates at a particular voltage and I could be wrong!

Hi, I received your PM. I agree with the guys about the heat issues, longevity, and battery life etc. The answer to your question #2 will help you better understand things.
In all kernels, there are frequency/voltage scaling tables. For every frequency step (clock speed) in the table, it corresponds to a specific voltage. It gets a bit more complicated than this of course, but that is the basic way things are setup in the kernel. The higher the frequency, the higher the voltage is required to be to keep the CPU (or GPU, bus, RAM etc.) stable at a given clock speed. The more voltage, the more current, and the more heat is generated. The longer you stay at higher clock speeds/voltages, the better the cooling system you need to have. Supply regulators are defined to feed the core and rail voltages so that the processor can live in a happy environment no matter what it is being asked to.
As far as power consumption, it's all about getting a unit of work done in a timely/efficient fashion using the least amount of power consumption. If the phone is sleeping, the word "timely" takes on a different meaning so then it is mostly concerned with power consumption and getting the background tasks completed effectively without having the phone experience the sleep of death (SOD). What you are talking about is the theory of "race to sleep" so that the work can be done quickly and the phone can go back to sleep where it uses the least amount of power (clocks actually turn off during deep sleep and cores are turned off). However, there is a happy medium to this theory and heat and battery consumption are the main enemies. Heat can also rob efficiency, more current is required when a circuit heats up. The more a phone wakes up to do syncs for email, apps, social networking, missed calls etc., that work can stack up throughout the day. The question comes down to how can the device get this work done using the least power and keep the device cool. On the N4, the lowest frequencies can use ~700-800mV per core while the highest frequencies can use ~1100mV. There is a drastic difference in the amount of heat generation between this range.
I think this should give you the general idea and maybe more that you wanted to know! Here are some links to check out if you are interested. Google and you will find many many more articles and research papers.

Thanks a ton !!!
Just picked up an XT1527 (full package, box, accessories, everything) from a craigslist seller for $40 - I figured it would give me something to play with until Motorola ships my "free" Moto X (32GB 2013 model) as a replacement exchange for my old Atrix HD which bricked when I installed the last update for it. For the record, this is the Cricket model.
Upon playing around with it for the past few hours, however, I've noted it tends to run just a bit warm even when I'm not really doing much of anything so I started checking into it - I'm still pure stock, mind you, 5.0.2 build LXI22.50-13.4) and I'm thinking about rooting it and perhaps checking out the CM12.1 build but there's no hurry at the moment.
Having said all that, I grabbed CPU-Z and took a peek at the SoC specs: it shows an idle speed of 800 MHz for all four of the cores even in spite of them having a 200 to 1.2 GHz range. One would think that the device would ramp down to 200 MHz when idle and not doing much of anything at all but, that's not the case so far.
So I grabbed System Monitor Lite to check just in case CPU-Z was reading things incorrectly and got the same exact results. Upon checking the pie graph it clearly shows a range of 800 MHz to 1.2 GHz and nothing below it.
Has anyone else noted this issue with the Moto E 2015 model or... am I just so new with this thing (having owned oh, maybe 200 other devices in the past decade and doing some rather intensive customizations on 'em) that I'm missing something here and just not even noticing it?
Had hoped to keep this device relatively clean and stock but, it appears that's not practical if this CPU speed situation can't be resolved. I see there's basically only the one custom kernel available so far (Squid) and while I'm not opposed to using it once rooted/etc I'm still curious as to know why this thing isn't ramping down the clock as it should. It's using the default interactive governor as well, would be nice to be able to alter that but again that's where it gets more complicated.
Anyone else noted this on their XT1527 (or any of them, really, just as long as it's a 2015 model) or would someone else that's running pure stock be willing to check their CPU usage with CPU-Z or System Monitor or something else and see if it's not ramping down below 800 MHz as it actually should? Obviously the battery life would dramatically improve if this thing would slow down as it should - there could be some new Qualcomm trickery at work here that I'm not aware of, but if it's capable of dropping back to 200 MHz, it damned well better.
Any comments and suggestions are appreciated...
ps
Also I've noted the GPU doesn't ramp down to 200 MHz as it should either, it hovers at 310 MHz almost constantly which again is just another waste of battery when staring at a static image on the screen (save for the info updates themselves but that's not really a thing that should or would trigger a big spike in GPU speed).
o.o thank you so much. You'd wonder why. Well, yesterday (I think) I made a topic about how my phone drains battery abnormally and I just checked with the app you said (cpu-z) and it seems I have the same problem. My phone feels warm almost all the time and it also keeps working up to 800 MHz in all cores. Also, I own the same model and someone in the other topic told me that battery should last 2 or 3 days without doing something. Oh anyway, thanks because now I have a hint about what's going on. Maybe its a manufacturer problem.
For some reason, Motorola set the CPU idle speed to 800 MHz. I don't know why. I lowered the idle speed to 400 MHz on my phone, and I'm not noticing any performance degradation. I haven't noticed any heat or battery issues though. My phone stays fairly cool, even under heavy load (like running benchmarks repeatedly). I've undervolted my phone slightly, that may reduce heat a bit, though I don't recall having any heat issues without the undervolt either.
Well squid, I'm guessing you are using a pretty customized setup at the moment including the kernel you've created so, I'll most likely end up getting a similar situation I suppose. Since the Snapdragon 410 can do 200 MHz to 1.2 GHz it damned well better do it; if Motorola for some reason chose to "hard lock" it at an 800 MHz idle speed that's a bit ridiculous and will only serve to hamper battery life overall.
Performance isn't the issue here since as soon as some CPU power is required it'll ramp up as expected - the issue here is the 800 MHz "bottom" which should actually be 200 MHz. That's a big difference in terms of overall battery life in the long run.
I owned an LG Tribute in late 2014 and was regularly getting 8+ hours of SOT with that which is powered by a Snapdragon 400 (1.2 GHz quad core) and that has a 2100 mAh hour battery - the Snapdragon 410 in this Moto E should be better for battery efficiency + we've got a 2390 mAh in it so, as long as it's ramping down to the 200 MHz "bottom" that it actually should be hitting then I, for all intents and purposes, should be able to expect or even exceed that 8+ hours of SOT without issues. The Tribute has an 800x480 panel in it, the E has the 960x540 so in the long run that increase in pixels should be covered by the increase in battery amperage (290 mAh more).
This Moto E 2nd gen model should be able to do 7 hours of SOT without breaking a sweat, even with cellular/Wi-Fi/Bluetooth/location services on and functional.
At least that's my goal with it... I'm on my first full charge since I bought it earlier today and currently at 58% with 3.5 hours of SOT and that's using Wi-Fi a lot with video playback as well. I've been keeping on top of the Baltimore riots that are happening presently and monitoring things using Scanner Radio Pro as well as a lot of surfing for info and news too. So far so good on the battery life, but obviously it can be much better as long as that CPU speed can be brought under better control.
