[Q] My device keeps powering off when the I put the screen to sleep.

For some reason since this morning after a full night of charging everytime my screen goes to sleep or I pus the power button to put the screen to sleep the device completely powers off. Last night I did flash infusion to oc/uv but had several issues and just kept the the device clocked at 12k and did slight uv. Im using setcpu and have a profile setup for screen off but I disabled in hopes to remedy the total poweroff. Any suggestions? How can infusion be removed?

Flash community kernel your getting sod or try removing your Oc UV settings

All good
Infusion kernel is great kernel but your settings are going to be trial an error play around with.UV that's usually the probably with sod

Question about uv. is less best ie -25? and what does disabling the various clock speeds do?

Try using setcpu to throttle your frequencies. If you're having sod that usually means your phone isn't getting the required voltage for your CPU and you're choking your phone.. See if you can set it at 1200mhz and 800mhz on performance mode and see where that leads you.

Thanks I will give that a try. to oc really isn't my goal just to improve battery life. Right now seems to be working ok @12k with frequency uv @75-50

SoD actually usually happens at lower frequencies - after all the phone tends to stay down there when the screen is off.
Typically SoD results from too much UV from 100-400. I never was able to go more than -50 mV undervolt, others hit -100.
netarchy's Gingerbread OC config is a bit different, instead of setting modifiers from stock you set absolute voltages. (No binaries have been released of his kernel until more testing is done - but the source is out there!)

You guys are great everyday i just read and read and im amazed by the information and knowledge passed on. I learn something new every few pages. As for my oc/uv prob i've stuck to minimal uv with no oc and screen off profile and everything is working aok i did switch to the b version of infusion so so far so good. Ive read 28 pages today on the new infusion v2b2 for gb and that will be my next conquest. To all thanks a bunch and continue to the good work and especially helping out the new guys like me. And believe it or not im an electrical engineer lol. Again thanks and much appreciation

sounds a bit like unhelpfuls kernel from the eclair captivate days. he had absolute voltage values and other freatures. will the gpu clock be configurable? that would be awesome. under clocking the gpu and agressive uv and ucing the cpu could add hours to the battery life. with 2.3.3 you could set the phone to 800mhz and the gpu to 182 or 166mhz could probably give little negative performance in every day use with exceptional battery life.
to the op:
sod can be a problem especially if you overclock. it seems the cpu doesnt like rapid voltage changes. i can uv -200 acriss the board if i dont overclock. if i do im at -150. the 200mhz clock is almost never used but i find if i disable it im more prone to sod presumably because the voltage and frequency jump to 400mhz is too great. it can help if the 100mhz-200mhz clocks have less uv than 400. if you loose stability on 1200 at -100 then maybe set all clocks to -75 cept 100-200mhz which you may set to -50.
this isnt a rule though. you might be able to uv 400-1000 settings quite a bit more than the 1200 setting just if you have sleep of death you generally dont want agressive settings on the 100-200mhz.

Not a clue - I only know what netarchy has done, not what he plans on doing.
The architecture of voltage/CPU frequency control is significantly different in GB kernels than Froyo. In general it's cleaner, so a lot of the issues with rapid frequency changes might go away in GB. For example, there's some code in the base kernel that's supposed to facilitate rapid voltage changes (not exactly sure how... the only documentation people outside of Samsung have for the MAX8998 is kernel source code.)

Well guys I have some news. I continued use with set cpu no oc just uv on freq above 624 @ -75 and I kept my screen off profile set to 644 max powersave scaling, and my battery life has been outstanding i check emails frequently been texting all morning and playing wwf and im @ 70% after 4 hrs of use. I know I read % doesn't mean much compared to some volts ratio but I think this is worth mentioning. And for my purposes the goal has been achieved in extending battery life and still having exceptional performance.

Oh and I wanted to add that my phone recharges much faster especially with the screen off with these setting. Maybe nothing new to you but def a plus for a(us) neewb's reading.

[GUIDE] Undervolting Settings to Maximise Battery Life

I have been playing around with my phone , undervolting it to see which are the best settings. Basically undervolting is like limiting the amount of power your device uses
My battery has greatly improved undervolting my phone!
Here are the optimum settings to use
What you need:
- Sense ROM (which has Virtuous OC Daemon installed)
- Unity Kernel V9
- OC/UV Beater 1.7 App
Install the OC/UV app.
Go to the voltage tab and you can configure from there! Don't forget to save your settings!
I have put my phone to some tests. I changed some UV settings and now I'm getting good battery life!
Set your UV settings -50 across all CPU Speeds! (Permanent profile)
I have been testing this settings for over 7 hours on my phone, perfectly stable!
Or you can use -25 if you wish...
I tried -75 and within 2 minutes my device messed up! My music player kept randomly pausing/unpausing, and then my phone froze completely!
I had to pull out the battery!! (I risked a fried eMMC chip!)
I set my profile for testing a 'temp' one , therefore it wouldn't survive a reboot. So my phone was back to -50 after I put the battery back in. All good now
Quick Summary:
-25 is safe
-50 is even better, been testing fine all day for me
-75 or lower, STAY AWAY FROM THEY WILL MAKE YOUR DEVICE UNSTABLE AND RISK A BRICKED PHONE!
Sorry for this guide being all messed up and long. I will edit it soon to make it more organized
~Disclaimer~
I have already warned in the thread, about the dangers of UV , so I tale NO RESPONSIBILITY IF YOUR PHONE IS BRICKED FROZEN ETC.
USE AT YOUR OWN RISK!
IF IN DOUBT DON'T USE THESE SETTINGS.
Please feel free to share your opinions in the thread, whether your battery Life is any better or not
Hit the thanks button if this has been any use for you
Cheers!

great advice! what are the dangers involved with undervolting? apart from risking having to perform a battery pull if it freezes.
Are there any long term risks or damage that can be caused by undervolting?

Not that i could think of!
If anything, UV preserves your phone for longer!
It will allow the phone to require less power to run hence saving stress on the CPU (?)

Sorry for offtopic/possible hijack, but the greatest battery saver for desire s is imho lowering screen brightness to 25% instead of auto bright mode (whenever possible, i.e. indoor). Combining Your method with this may result in really huge savings. Gotta give it a go.

would this undervolting work with my current rom "RCMix3d VoidU v1.1a (Android 2.3.5 with Sense 3.0)" with htc stock kernel?

Sorry, nope, UV won't work with the stock kernel :/
It only is compatible with Unity V9 (not the older versions)
The only bug unity has is the fron camera is upside-down
But a combination of Unity Kernel and controlling the CPU speed and UV with the app listed in my OP, wow! Battery life is fantastic!
This app is much more effective than other CPU apps aswell. It is well known.
My battery dropped from 100% to 89% on for 8 hours
(15 mins 3G browsing, 20 minutes music listening, 15 minutes messing around with the phone, and the rest 7 hours + on standby!
No joke!

Well gonna give it a try at -25 for a few days to see how it goes
EDIT btw how can i tell this is working ?

Good
Since we are on the same ROM + kernel too, I can tell you -50 is 100% safe for us!
Been using my phone quite heavily since I got home, flashing mods via recovery, rebooting, etc ..
And phone hasn't frozen or become unstable yet
Good stuff
Also guys please share whether this helps improve your battery life!
EDIT: it will tell you on the OC app. On the voltage tab, it will tell you your current voltage. Remeber to hit save though, after you changed your settings!

Yeah I did that ,and can see it's set to 25 below default. just wondered if it could be monitored.
Mine gets quite heavy use with emails and twitter and facebook and whats app ,so will be interesting

Mines only ever at about 20% unless I'm outside and even then its only about 40% and not used much. battery would just disappear otherwise lol

My screen brightness is as near as or below <20% in normal circumstances and auto when outdoors - in direct sunlight.
I use UV of -25 across all the frequency settings. I did try -50 once and it hung my device such that it would not respond to either the 3 button reset or any adb commands and I was forced to resort to a battery pull, so for now I'm sticking with -25 unless I read significant remarks to the contrary.
My default OC settings are:
Code:
wake gov = virtuous
min = 122000
max = 921600
sleep gov = virtuous
min = 122000
max = 245000
My low battery settings are:
Code:
wake gov = virtuous
min = 122000
max = 768000
sleep gov = virtuous
min = 122000
max = 245000
EDIT: Incorrectly altered these figure initially correct now!
Have certainly seen an extended battery life on this ROM and with these settings, especially when the phone is asleep..
CPU Spy is a great free application for analyzing which state/speed your CPU has been in over time - so very useful.
Plus must credit both the author of the OC daemon (rmk40) and the author of the free [APP] OC/UV Beater2 v1.7 - GUI to change Virtuous_OC, Andrev_OC & Viper_VDD levels application (cjoliver) which is used to easily configure these settings both here from XDA.

Really useful info, thanks very much! Got some questions though if you have a sec?
Is there much difference using ondemand vs virtuous for low battery? Also, I notice your sleep max for low battery is higher than the sleep max for normal of? Thanks!

Opps! I messed up there entering my figures night, I've EDIT'ed my above post, would appreciate if you edited your quote in your post above, so as not to confuse people.
Not 100% sure on virtuous versus ondemand. Virtuous = is tweaked smartass (or smartass 2)

Same here (with the -50).
My phone got hung after 2-3 minutes.
UV numbers are really statistical, some parts will leave with the -50 and some will not. Same goes btw with the -25, for most of us it will work, and for some of us it won't...

Thanks, good to hear that I wan't alone.....so did your phone come back to use in two minutes, then enabling you to revert the numbers....I suppose that that's the great use of the TEMP activation settings!!

Any chance that you could edit the Title of this thread so that it covers Over Clocking/Under clocking and Under volting as the three are closely related.
That may make more users add positive useful input. What do you think?

i want to flash unity v9 kernel to allow me to UV and UC but am concearned about the video recording issue. As i use this frequently and cannot afford for it not to work. does anyone have any idea when v9 will be updated to fix this issue?

The recording issue of FC is solved by changing the setting so that it does not record in stereo

I was using TEMP profile, so after the 3 button hard-reset, it was back to normal.
I'm now on a PERM w/-25.

Battery Drain while sleeping

I fully charged the phone to 100% and turned it on at 7:45 then I went back to sleep. I woke up at 10 to see the phone at 95%! Now, I'm currently using the Anker battery & I'm running on ARHD 3.6.13 with faux123 v0.2.8 kernel. The brightness is at its lowest & auto-sync is off. What should I do?

I recommend using Battery monitor widget Pro to see how much mA is phone using during sleep and when screen's on. Then install Better Battery Stats ( http://forum.xda-developers.com/showthread.php?t=1179809 ) and figure out, what is eating your energy
also, try undervolting

What's undervolting?

Undervolt makes your cpu use less energy. for undervolting try using system tuner pro or faux clock (here's link for faux's RootzWiki: http://rootzwiki.com/topic/4550-app09-beta-snapdragon-dual-core-oc-control/ ) But be aware that not every CPU handles heavy undervolting well. Do nandroid backup, then Start with -25mV.

edit
Try changing cpu governor to intellidemand (faux's kernel default) and min speed for cpu to 192. It may slightly improve battery life.

Hi,
When I was on 3.6.x,it was suggested that I try a Bricked kernel,which you can find HERE
I am not sure which one,but they tended to be more battery friendly than faux.
Read the thread.
You might get some valuable information.

solid battery drain with cybergr rom ver.12

I am experiencing poor battery life with cybergr rom version 12.
settings are governer - ondemand
min cpu freq - 200
max cpu freq - 1000
kernel - tried both matrix 19.5 as well as air 4.
battery drains by 10% in every hour.
I have to recharge my phone thrice a day.
I did fresh installation but it did not solve my problem
please help.
I really love this rom

BetterBatteryStats. Also, try a new ROM if need be.

What's your best Rom/Kernel combo? NS4G

I'm looking for a rom/kernel combo that's good on both battery and performance. 2.3.x is preferred but 4.0.x will do. Thanks in advance!

PLEASE PLEASE PLEASE do a serach. In the past month there have been about 15 threads with the nearly identical title!
Last one was closed because there is NO BEST rom/kernel.

How hard is it to experiment? Seriously.

if you want better battery life, get a bigger battery. all those tweaks might get you 5-10% more battery life and some cause instability. they also tend to have a hit on performance, so I'm quite sure you won't find anything that covers your needs. The best battery savers are: You not using your phone constantly, not having installed any misbehaving apps, being in an area with good network coverage, apps not syncing or trying to access your location every 5 seconds.
So if you want something stable that works, get a ROM that's close to stock (OR CM) and use the kernel with the fewest tweaks, don't OC, don't UV (both useless IMHO). Otherwise flash ubersuperOMGItweakztheshitsoutofthisphonROMv17 with air kernel.

I beg to differ with your first statement. On GummyNex I could pull in the 6 hours with 3G with the settings in my signature. Same settings on Paranoid get me just in the 5 hour mark while using 2G. That's hardly 5 or 10 minutes. On every other ROM I've tried o struggle to get in the 5, even 4 hour mark.
Also my performance is pretty good, can't complain. Gaming with incredibly heavy games is iffy, but light heavy games are fine. Max Payne would be wonky at times but Shadow Gun is smooth.
(When I say with 3G or 2G on, I mean that's the type of data I would use. Not that I had it constantly on. I do use it a lot though. I'd say 4/5 of the phone's usage.
But yes. The things you listed afterwards are very true.
And getting an extended battery would be best.
Nexus S (GMS i9020a)
Paranoid (1.6 - 4.0.4)
Matrix Kernel (CFS - 20.0)
Ondemmand (800/200)
Deep Idle (Off - Noop)
Live OC - 100 (400/800)
BLX - 98 (Inverted Apps)

6h is quite a long time . But I believe you... what I wanted to say is that most of the time, battery life is limited by the hardware and your usage. Most tweaks do more or less nothing, and the ones that do change something don't work on all devices because they push the hardware to their limit. If those tweaks work for you that's great, but they don't have to for others. My phone is limited to 4-5h of screen on time, I guess mostly because my phone can't handle UV and I have an SLCD, which means I won't save power on using inverted apps etc.. But I can easily get through the day so I can't be bothered tweaking the **** out of my phone .
