Undervolting? - Droid X General

I do it on my laptop, was wondering if I can do it on my phone to save power?
I looked aound a bit and everyone seems vey focused on overcloking. I don't have a problem with the 1Ghz speed, was ust wondering if I can stay at that speed and save some juice and if it' safe.

Yes you can. Get one of the apps off the market either unstable apps or jrummy. I use the unstable version to under clock from stock down to values of 50, 43, 36, 25. Which is quite a lot lower I think.

The apps are only .99 -so you can't go wrong with 'em. But I like learning this stuff and tinkering. So you may have already checked out this thread...

It is about overclocking- but you can use the same information to underclock. You just need the overclock.ko file and then adjust the setscaling.sh file so that it uses lower vsels.
I did a little write up in that thread...
http://forum.xda-developers.com/showpost.php?p=8771591&postcount=43
so if you want to check into- once you fool around with it a bit- it is not that hard. I now actually have 3 scripts I can run. 1 for stock clock speeds undervolted. 1 for stock speed stock voltage. and 1 for high voltage clocked to 1.3mhz.
good luck.

it has definitely been a great mod to my phone. I'm running stock speeds and ULV. Battery life has been phenomenal.

The stock vsel is 56, right? I've tried going down to 54 and the stress test in set CPU goes well for 5 minutes. At some point between 5 and 10 minutes I get an error.
Is that normal and I should go with 54 or should the test last a lot longer without an error? Or is the stock vsel higher?

58, 44, 33, 27 are my vsel values oc'd to 1.125. Any higher oc will slow me down to a crawl.
To answer your question, I think stock vsel is 62 on Froyo.

I have been running the Ultra low voltage 1.3ghz preset from jrummy's app for a couple of weeks now with zero stability problems. Improved my battery by about 15-20 percent. I have seen warnings about stability with ultra low voltage but I guess I got lucky. Low 18's in Linpack and upper 1600 quadrants.

@aggie12 Care to share your vsel numbers? Im doing the same stock cpu speed just undervolted but I have hardly noticed a difference in battery life. How many hrs does your phone last in average use?

I typically get 36 hours before I get nervous at 20%. This is without juice defender, just straight 1ghz use on regular battery manager

How is 36s hours even possible? I get around 10-12 hours of use, but I'm a heavy phone user...
Also, is it possible to undervolt using setCPU?

No- set cpu only adjust your clock speeds- not the amount of power the phone is drawing to obtain those speeds. The .99 apps will allow for undervolting though. Or if you do a little study on the OverClock thread- it is not to hard to do with a script.

@Daali What are your vsel numbers? Mine are:
1ghz/45vsel
800/40
600/30
300/18
I get only 12 hrs of heavy use.

[Q] SetCPU for MT4G?

Is it safe to install SetCPU on the MyTouch4G now that we have permaroot? If so, what are the settings we should use with it? Just not sure if the current kernel has been tested with SetCPU or not, and if it works what version of SetCPU... 2.0.3 or 2.0.4?
Thanks.
I am running 2.0 4 with autodetect. Set at 1024mhz performance. No issues and been running 3 days now.

The closest options for this are the following:

What did you use for the scaling and priority settings?
EDIT - Added a screenshot to this post. I've tried both 2.0.3 and 2.0.4, and no matter what I set for the minimum setting it stays at 245 (not what I defined). Does it not work then on this stock kernel?
I was going to say the same thing, from what I have seen on my phone setcpu is not doing anything. It won't change any of the clock speeds whether boosting the low end or limiting the high end.
I have tried a few things like setting profiles for less than 75% battery to lower the max clock speed and that doesn't work either. Am I crazy or are others experiencing a placebo effect on profiles lowering clock speed when screen is off?

For HTC phones need to be rooted and also disable perflock. In setcpu: menu->perflock disabler. I set my perflock to disable on boot.

Hot damn, that fixed it! Now to test it out further to see how well it works here. I'm not looking to overclock, just underclock when I'm not using the phone. Thanks for the tip!

Just an average power-user. I email and text a lot as I own a consulting business. I am constantly on the go and need my battery to stretch as long as possible.
That is why I kept the stock kernel and didn't over-clock. I simply removed all the bloatware and non-essential apk's that I didn't need and set up a few profiles in SetCPU and now I can get an easy 2 days of power use out of it.
As I still employ the stock kernel and stock ROM I have no lag what-so-ever. Response is perfect IMHO.

SO I am new to this... I used your same settings and my bat shows 56%. On the my screen it still shows that its jumping from 1024-245. Am I missing something?
EDIT: N/M I am just dumb and forgot to preflock!
So I set my profile to have
Screen Off Pri 75 Max 3K Min 2K
Bat 75% Pri 50 Max 7K Min 2K
Bat 50% Pri 50 Max 3K Mn 2K
I will let you know how it goes but I am hoping for some good bust in bat life.
Had some issues when waking the phone, so I changed the settings on the screen off to Max 768. Going to test.
I also moved the 50 Bat to 30 and still getting good life out of it.
Well I have been experimenting with some profiles in setcpu and I have noticed a great increase in battery life especially when in standby a lot.
So i have done this according to what works for everyone else. But... my battery still drops from 100 down to 40 in about 5hours and it has been this way since the 2.2.1 smh. I dont kno what to do. I do text alot and get on facebook mobile semi frequently but mainly text and omg the phone gets up to 104 degreez wen using or charging. Any suggestions ? Or anythjng i may be doing wrong

SetCPU configuration

Hello,
I just installed SetCPU and configured some profiles. I'd like to hear comments about them:
Screen Off 83/83
Charging 667/83
Battery < 15% 83/83
Battery < 30% 222/83
What do you think of setting 83/83? Too low?
How can I overclock?
I'd like to set a profile for temperature controlling, what is considered a high temp?
Thanks!
I would like to know about this as well. How has those settings worked out for you so far?
Using 83/83 was way too slow. When I had screen off and wanted to turn it back on, it would take too long.
I'm currently using these profiles (in order off priority):
Charging 667/83 (ondemand)
Screen off 222/83 (conservative)
Battery <30% 222/83 (conservative)
I haven't figured out how to overclock yet.

Do you get lag after turning the screen on?
I used to have anipet Aquarium Live Wallpaper + ADW Launcher EX, and had huge lag when turning the screen on - with 222/83. I stopped using the Live Wallpaper, and it got better, but there's still lag sometimes. I don't know how heavy ADW Launcher EX is, if it is it's fault or not.
Using performance scaling, if I'm not mistaken (the documentation page of setcpu is down) forces the cpu to always run at the max frequency, so it'd be the same as setting the max and min frequency as the same value, right?
I'll give a try at using conservative instead of ondemand and see if I get less lag, though I'd expect exactly the opposite!
What's the point on downclocking the CPU while using the phone ? I mean, 333mhz makes me think i bought a chinese phone (And not a cool one like the ZTE Blade).

i totally agree, i would love to able to overclock it, not underclock it
i have undeclocked it coz i want a longer "ON" time...i am texting and callin ppl most of the time so battery lasts jus for a day.i don't wanna charge it everyday.plus using at 333 isnt so bad..i don't play games(much)...and even when i do(angry birds,paper toss) it works fine...u will get used to it....and whats the point in overclocking this phone? with a crappy resolution no HD game will run on it.
the only thing that sucks at low speeds is the gallery.however this can be "solved" by using the Quickpic app.it's better organized and hella fast.but it lacks the fancy looks...
@iomartin..there is no delay or lag and i have disabled the lock screen also.i use go launcher btw.

Wow thanks for this. I used these settings except for the last one (underclocking when the cellphone is being used)
Last time I recharged was 63 hours ago, and battery indicator still shows 50% left! I have:
- Watched an episode of Kenny vs Spenny (640x480)
- Played ~1h of games
- Surfing + downloading ~30min on Wi-Fi
- Installed ~ 10 apps
- Texted about 50 messages
- Made about a total of 10 minutes of calls
- Sent songs through bluetooth for.. ~10 minutes
- Listened to music for about ~30 mins
Still 50% left? Amazing. Of course this can (or is) a problem with the crappy indicator and it can quickly decrease to ~15 in a heartbeat, but it still is pretty amazing.
Phone says it has been on for 73 hours, I wonder if that's the actual time I recharged it for the last time, or if It's the last time it was charged?
Once again thanks for those profiles. First time I used the app I reckon setting the same but I used OnDemand scaling (What's the difference between these btw?) and It lagged like hell when I turned the screen on again. None of that happens now, the phone works the same way as if it had normal clock speeds.
Oh and I don't use 3G and I've got APNDroid blocking all internet connections. I wonder if that does anything to the battery life?
EDIT: Now I used some bluetooth for 15 mins and made few calls and it got bumped down to 15% and told me to recharge. Guess It'd still work for about 6 hours on stand-by but still the battery life for me was ~67hrs, whilst being ~48 before.

50 hrs of battery life with Burt Droid Rom

HI guys,
I wanted to share with you what i have done on my phone, i got over 50 hrs of battery life on it.
Now i did not have a lot of phone calls these 2 days, but i did have one phone call that lasted almost an hour.
I also surfed the web, and downloaded a few apps under this battery as well.
its showing 2 days 2 h 30 m and i still had 4 percent left.
Honestly I do not know if this is good or not, but iv seen where people are happy with 20+ hours so this should be in the zone of goodness.
my setup
Burnt Droid lasted build.
setcpu- underclock only, no overclock,
juice- purchased the ultimate, so at night it kills everything but phone.
here is this pic

I get great battery life (70-80* hours from full charge to dead *This battery life was directly after a wipe of the battery stats. After a few weeks of regular use I'm seeing about 60-70 hours of life (full charge > dead) with these settings:
ROM: SkyRaider 3.5
Kernel: Incredikernel
I'll echo another member's post. Turn things off that you aren't using (i.e. 3g, wifi). I will only turn these things on when in use (checking email, surfing web, etc). Along with 3g, and wifi, your screen brightness is a huge battery killer. I have mine set around 20%.
Another thing I found to help is having SetCPU profiles set. Here are my settings:
main: 1075 max, 245 min. ondemand (set on boot checked)
screen off: 245 max, 128 min. priority 100
Temp>39 C: 245 max, 128 min. priority 99
Charging/Full: 1075 max, 245 min. priority 98
Battery < 20% 883 max, 245 min priority 97
Battery < 40% 998 max, 245 min priority 96
The above settings give me outstanding performance while the phone is in use, and really help to save battery power when not in use.
Dang. Impressive! That's for sure. I don't like the idea of underclocking much though. How was performance? Everything running smoothly?

[Q] [Opinions] Undervolt Settings.

First off, I would like to apologize in advance in case a thread like this exist and I can't find it.. :/ (Search is down, tried Googling) also, if anyone believes this to be in the wrong forum.
ANYWAYS! This is intended to be a preference/opinions thread centering around your OC/UC and Undervolt settings. Feel free to post your current set-up in Voltage Control (or any app of the like) and what Kernel you are running! I wanted to start this to get an idea of what everyone else is setting their UV and CPU clocks to, and possibly give a few of them a try on my own device. :]
Personally all of my clock speeds are at their defaults except for 1000Mhz @ 1200mV. (-75mV). I am also rocking Genocide v1.0 and getting a decent 30hrs of battery life with pretty moderate use.
Post away!
It is kind of pointless since every phone is different so cannot do exactly the same as others. Most can't do 1.4Ghz and most don't wake from sleep at 100 Mhz. All depends what you use your phone for. Mine runs fine at 1.3Ghz except for some TV apps will freeze.

I believe that would be my point however.. curious as to what other people are running as far as cpu and voltage is concerned. Their success and failures. What people can get away with and remain stable. I, and others, could then try their setup (taking precautions of course; ie Nandroid backup.) And see what we get. Who knows, maybe I might adapt a set up that runs better on my device than my current one.

Yes, every phone is different, but that is just more of a reason to collect data - perhaps a baseline can be established, which would be helpful in determining if a particular phone is messed up or just at the low end of the scale. Right now it is hard to determine if a particular phone's troubles are caused by low quality or by damaged hardware.
I keep all voltages at stock, and don't use any OC - my phone runs fine as is, and the battery life actually seemed worse with UV (and my screen felt hot with the screen UV).

My phone wakes from 100 but won't do 1.4ghz for even a couple seconds before reboot but 1.3ghz lasts about 20 minutes before reboot and 1.2ghz is stable. As for undervolts it can handle -25 on 1.2ghz and -50 on 1 and 1.1ghz -50 on 800mhz and that's it otherwise becomes unstable and reboots. Battery life and performance seem to meet at 800mhz with a -50 undervolt games run smooth too and 12 hours of battery. Oddly enough benchmarks are consistantly higher on 1.12ghz than on 1.2ghz I wonder if I'm the only one?

Just to throw it out there. Aggressive undervolts will do more harm than good to your battery life. By that, I mean you'll drain your battery even more.

I can only use Genocide kernel to get 1.3ghz at stock voltage with since all the other choices are uv'd. My last two Epics were able to handle uv'd 1.4ghz by 50mV but I'm not really complaining as I think this is a new phone they gave me and not a refurb. I currently have 100-400 uv'd by 100mV, 600-1000 uv'd by 75mV and 1300 at stock.
My phone can handle 1.4 Ghz but only with the stock voltages. If I try to touch it even by 25mV it locks up.
Who all has enabled the 100Mhz step? I noticed when I did my phone went into Deep Sleep a lot less by a noticeable amount. Staying at 100Mhz a lot.
Always interesting to hear about all this theory behind the reasons for undervolting OC and UC, then to hear about the issues (at times extreme) some have. I would also like to know who uses the 100 step and if it is noticeably better on battery life than the 200? Unfortunately I am missing out on it if I am. Still running Genocide here, but with 1.0 at -50mv 800 @ -50 and 600 @ -25. Very stable and still at 30+ battery life. Having 1.0 down 75 made me nervous. although I hear people dropping it down -100mv successfully.

Good tip about "aggressive UnderVolting"...didn't know that actually drains your battery more. Might explain why 6 hours into my day, my battery is down to 30% already!!! I had it set at 1120Mhz UV to 1175mV (Stock = 1300)...
So now I'm going to try 1200Mhz only UV by 50...see what my battery life is after this!

Just to throw it out there. Aggressive undervolts will do more harm than good to your battery life. By that, I mean you'll drain your battery even more.

Can you explain how this is so? Is this based on any actual research, experimentation, or online documentation, or is this just your own opinion?
Unless your undervolt causes the CPU to hang (I've seen mine start to warm up when it's hung, until a battery pull), I don't understand how providing less voltage to the cpu will cause it to drain the battery faster.
If you change the voltage settings please don't blame the rom developers when you phone bricks...

800mhz is enough

Quick, and great battery. Overclocking is pointless unless you play games on your phone, or care about your quadrant score.

Yup, I agree with you
+1
I had a Milestone for 1.5 years on stock ROM (that is 550Mhz), pretty much served most of my needs perfectly....you know, the normal stuff you use your phone for.
I rarely notice my phone is underclocked... with smartass governor, it's more responsive than stock clocks with a less responsive governor.
Battery life doesn't seem improved, but I know that my weak signal is causing the problem here.

I Sunni it's different for me.. When in use it seems to drain about the same but last night I set the phone down around 11 worth 84% battery life and got up at 6 with 78% still and that's setting the governor to smartass
It's bad for me because my phone goes without signal about half the time in my apartment. I'll be moving soon so it's not a huge issue, but it is kind of disconcerting to feel my phone heating up from just sitting around doing nothing.

You could try disabling the governor and let one like, setcpu do it? Before I went Incredikernel I set up a profile in setcpu that whenever my screen was off it wouldn't run any faster then 128MHz but when on was set for either on demand or performance. Using two governors at the same time causes lag I've found so you'd have to be running a rom that doesn't already have one (that you can see and change) built in
Yea, this is true. OC'ing I thought it was giving me speed, but I actually took the time to really see the speed on OC'ing and to me it dosent seem to change. Well maybe alittle bit, but still. But yea, so I just hit 1ghz and I just leave it there.
Pete's latest w/Yennob-Base2 kernel at 1ghz and its going good.

Yeah I honestly can't tell a difference between running at 998 MHz and 1,113 MHz other than a physically hotter phone and faster battery loss lol

Ahaha, yea. Everytime I would hit 1.3ghz or 1.4ghz for the fun of it, my phone would get that way too. It would get hot and it feels like it would explode in my face and yea battery life would drop like crazy.
Personally, I find myself running into a wall with RAM more than with processor power. I really hope the next Nexus at least doubles it.

Well the SuperOSR is only for nexus s.. If there was one for the ns4g, well then after reading that, I would be OC'ing like a maniac.

This. I'm really feeling the loss of RAM coming from a mytouch 4G. That extra 256MB really made a difference. Using juwe's RAM optimization script seems to help, though.
Ehm, how can Ram be a problem?
Android is managing it itself and can't run out of it, usually.

Things get killed that you don't want getting killed, and when it starts to run low things slow down considerably. It's not that something won't run, but it may run badly, or cause other apps to close that you were multitasking on, which is inconvenient.
I average 16 hours with normal for me use, which is a lot of texting, Facebook, internet browsing, listening to music.

How so? I normally get around 9-10 hours max with moderate use, also depending on the signal i get half the time.
I use netarchys latest bfs kernel with proton to undervolt all CPU frequencies to -20mv. And I have the CPU limited to 100-800mhz, with the on demand governer. With those 2 thing I get 15-16 hours everyday. I also usually let my batter get down to atleast 5% before charging.

i always Under clock the phone with SetCPU to save battery life
