Long time lurker, but 1st time poster.
I've noticed on my Revolution that the CPU always runs at 1ghz. I thought CPU throttling was a standard feature in android?
Anyhow I installed CPU tuner and I get much better standby battery life now (~2% drain/hr when not using phone vs. ~5% drain/hr on standby). The phone runs mostly at 124mhz w the screen off. My problem is my revolution reboots pretty frequently and sometimes even just completely shuts down w CPU tuner on. I still get reboots once in awhile w CPU tuner turned off, but much less frequently.
Anyone else having this problem? I also have green power running in the background to turn off the data connection w the screen off. Are you guys who use setCPU not getting reboots? If so I'll spend the $2 and give that a try.

I honestly don't think anyone has been messing with the CPU until the CM ROM is released.

As far as I've seen, the Revo's CPU does automatically speed scale to the necessary load.
If you're running lots of apps in the background, with the screen on Android will keep the cpu at full throttle to provide a smooth experience for you.
As soon as you turn off the screen, it will throttle it down as much as it can.
If the phone's rebooting on you, that's because whatever cpu tuner is doing may be keeping the cpu speed too low for the demand of the OS, then the watchdog kicks in when it thinks the cpu is stuck in a loop. (watchdog wants to be petted every 30 seconds, if the cpu misses that, the watchdog reboots the phone)
I use setcpu and have no reboot issues.

throttle
I use android system info to show the CPU speed. It shows the % of time my revolution is running at each speed. W/o using a 3rd party app it always shows 100% at 1Ghz. W CPU tuner running it shows 50% at 122Mhz, 25% at 1Ghz, and 25% in between.
I don't think I'm running any apps thats sucking up a lot of CPU. I'm rooted w most of bloat removed.
Am I the only one not seeing any CPU throttle on stock?
i'm not seeing any throttling on stock.
setcpu drastically improved battery life when the phone's off, and no reboot issues.
some issues initially with the phone not throttling back up quickly enough when i got a call, making me unable to answer the call, but played with the settings and made it so it automatically throttles back up to 1024 when i get a call, and now it's fine.
Exactly Im much happier with my phone now. I had the same issue when I received a call but set up the profile as u did and have no problems at all

I am using setCPU as well with no issues. I have mine set were the screen is off it goes to 124 and clocks back up to full 1GHz when it is on. Helps greatly improve my battery.
So what settings do you use? I get really bad lag when waking my Revo. Sometimes it will reboot after waking too.

I don't know if this is a CPU throttling issue, or a general REVO issue, but I get horrible horrible lag sometimes trying to get any programs to respond. Like press the home key, or click send, or anything like that. I'm running Decrap 1.1, I don't know if I have too many processes running or what.
Interesting. The Thunderbolt has the same issue. Is it the same CPU in that phone?
So just inherited my dads OG Droid. Currently rooted and runs Steel Droid (Mod Version 9000) and 2.6.32.9_RZ Kernel.
Phone is overclocked to 1GHz (125/1000 ONDEMAND).
Like the title says, the phone gets about 5 hours and then hit's 5% and keeps asking me to charge. If I charge it overnight and unplug it when it's 100%, it'll hit 90% idling (while I sleep) about 3 hours later.
Running Programs:
DSPManager
Words Free
Facebook
3D Digital Weather Cloc
News & Weather
3G Watchdog
Videos
SoundHound
Pandora
Temp+CPU V2
Now out of all the running apps, Pandora, Soundhound, News & Weather, 3G Watchdog, Temp+CPU, 3D Digital Clock are all widgets. Temp+CPU and 3D Digital clock are the only ones that actually run, the rest are just there in case I want to use them.
These stats today are from using Pandora for about an hour over Wifi.
Any ideas? Phone runs fine most of the time but I have seen the occasional lag where you have to click something 10 times before it opens.
I used to have a pretty big problem with battery life too, but even though I think they are somewhat silly and annoying the Easy Battery Saver app helped me quite a bit.
Wifi and using the speakers are heavy on battery life. Not sure how much difference it will make but try consolidating your widgets and app shortcuts to as few screens as possible.
Also your CPU governor might be set to something that lets the phone hog through anything at the sacrifice of battery. When i set my CPU to Performance my phone runs like a boss, while setting it to battery saver I get a little more lag but more battery, obviously. Not sure how/if your ROM will let you change that but it's something to look into.
I got it set to On Demand which might be the issue. The kernel is a low voltage kernel. How do ultra low voltage kernels run?
I did a battery calibration, downloaded Advanced Task Killer (Battery saver didn't work well, I'd always have an issue with 3G not activating) and got rid of all my widgets. Currently charging it up completely, I'll check it out tomorrow.
So the title is incorrect, it says 5 hours and 5% left. I checked the battery info at 5%. It said 4hr 4x min. About 10 minutes later it shut off so I didn't even get 5 hours to a full charge.
I don't have high expectations but coming from an Alias 2 that had the extended battery (I'd get a week of battery with my use), this is pretty disappointing.
Well I can tell you now, ondemand is NOT good for battery, what that governor does is make it so the CPU will go from MIN to MAX speed slots depending on what the phone needs, AFAIK it doesn't scale with need, it just goes to max. So your phones CPU was running at max most the time which kills battery.
Can't say anything about your ROM, but I use simply stunning 5.6 http://www.droidforums.net/forum/chevyno1/177728-ss-5-6-2-3-7-incl-1-battery-other-goodies.html Which, with his low voltage 1ghz kernel set to the smartass governor, I get anywhere from 8-14 hours of battery life depending on use. Using ultra low voltage kernels depend on your phone, some phones have trouble overclocking to 800mhz mid-voltage (mid-voltage is considered to be the most stable, but use the most battery), others can overclock to 1.25ghz ultra-low voltage, which is very rare. I would say try out all the different voltage kernels and see which one works best with your phone.
Also task killer = MAJOR MAJOR No no! The task killer will kill the apps, and the android OS will restart them, using more CPU time and making the battery actually not last as long, I would recommend learning how to use the supercharger script http://forum.xda-developers.com/showthread.php?t=991276
Can't say much about the majority of programs you have running, but I've found facebook does not like to play nice with the Droid, also, why use the 3D clock when the Droid comes with a built in-clock app? Pandora uses a lot of battery, so running it w/ the ondemand governor is probably what hurt your battery there.
Not many Droid users left out there, but I was and still am an extremely avid Droid user, so if you have any more questions just shoot me a PM and I'll help as much as I can.
Thanks! I got rid of all my widgets and installed Chevy's ultra low voltage 1.1GHz kernel on smartass. I lost 20% battery pretty fast but let's see how long it runs. I've had no force close issues so far. I'm a bit tempted to go to 1.2GHz ulv.
How much does the ROM have to do with battery life? I really love this ROM and it's interface. I thought the battery life really only had to do with kernels.
I also got rid of the clock widget and put a default clock widget. What's the built in Android one? Is that the "Analog Clock"?
Sorry for all these questions, I'm pretty new to Android. Only had this for 2 days (~8-10 recharges...)
Its fine, better to question and learn then to just get mad and over it, and Roms have everything to do with battery, they are just like kernels, some work AMAZING on some phones, while others can destroy battery life.
Like my rom, I found the perfect one for my phone, I get 8- (been thinking about it more) 20 hours of battery life on mine and it has pretty amazing performance too with the occasional hiccup.
And I thought you had the clock app installed for an alarm, not for a widget, my bad. I don't use a clock widget so I wouldn't know.. Also, I've found its not very good to run many widgets on the Droid, as it has limited memory and can only handle so much.
Well I got sick of it and reflashed the entire ROM. CPU governer is set to ONDEMAND 125/1000. Only*widgets I have are a simple clock (like the iPhone lock screen) and power control. Gonna see how it goes. So far so good but I'm saying that because I didn't loose 20% overnight. If I can clear the day, I'm good.
googlelover, what CPU Governer did you find to work the best with your phone?
I have been an Android owner for a while now, with the Droid being my first. Until recently battery life had always been an issue for me. Undervolting has never had an effect over a 20% improvement. And this is only when it's in deep sleep. Otherwise, in very general terms, undervolting can require a higher current aka worse battery life if you use your phone a lot. With undervolting comes the risk of data corruption in your phones memory and SD Card. What really kills your phone is screen on time, wakelocks, CPU overclock, and signal quality.
The last you have no control of. But if you're overclocking 1GHz or higher you have to realize that's almost twice the manufactured clock speed. As far as wakelocks, this is when something keeps your phone from going into a low power state. This can happen because of a rogue app, a buggy ROM, or having too many widgets. I ran into a ROM a while ago on my Fascinate that would stay awake if you had GPS enabled. The best you can do with your display power usage is to keep your brightness down. Hope this explains a few things
have the same issue

I already told you, the smartass governor, and like I said before, ondemand is not a good governor in my opinion. There are way to many factors in battery life to have anyone else be able to truly help you with it, all our phones are different and it really just takes time switching kernels, switching ROMs, etc to find what works with your phone
Sorry googlelover, I forgot you already said that.
So update guys. I've been going a day (so like 18 hours) of use after which it finally hits the 15% warning.
What I did:
Basically I reflashed the ROM and started from scratch. Before reflashing, I wiped the user data/cache/davick cache etc at least twice just to make sure it was really wiped.
I reflashed SteelDroid 9.0 with the default chevyno1 lv 1ghz kernel and gave it a go with just a simple clock widget. Worked well. One by one, I'm starting to install applications until I can figure out what was draining the battery fast. So far, so good. If I can get 18 hours on a 2 year old battery, I'm going to be doing fine with my extended battery.
One thing I did notice was that the phone back by the camera (where CPU is) isn't getting as hot as it used to. Makes me think that the phone was at a high clock speed in sleep. Another issue may have been my CPU temp/speed monitor. It was probably poling the CPU stats every second which made the phone increase the CPU speed because it sensed activity.
Try out the ROM I'm using. I absolutely love it. The interface is phenomenal and it runs very well.

(remove the spaces to see it, I wasn't able to post links normally because I don't have enough overall posts).
There's probably other ROMS that run better like the one googlelover is using, but I can't use the default Android interface anymore after using this.

Don't forget not many roms have the default android interface, many have themes to completely change the look, if your happy where your phone is, great! But if you ever feel like your phone is slowing down again, I'd still recommend looking around and flashing some different roms.
Thanks, I'll keep that in mind. I'm only using this phone for another couple months. I'll be getting the Droid 4 when it comes out. Looks like a really nice phone.
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
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.
A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
