Meaning, does the battery life take a dip when you overclock to 1.5ghz. Does it get any hotter? Is heat an issue at all on this thing? Also, any performance or battery changes from installing the tiamet kernel itself? I'm in the wifi xoom btw.
Strangely enough battery life seems to be about the same. Heat has not been an issue mainly due to having the dual core, however its something you always want to keep an eye on.
Battery life is affected most by the screen. Screen> Network connections > CPU > RAM
There was a thread that someone made a while back about the things that affected battery life the most. If I can find It ill send it your way. After seeing the charts I figured Id try changing some settings.
things I did:
1. Set my max cpu freq to 1.19 min to 488 same for all my cpu tunner profiles ( I wanted to have my phone running the same all the time)
2. Lower'd my screen settings. I didnt need a pocket flashlight EVERYTIME I unlocked my phone.
3. Turned off un needed network connections. Its not hard to turn them back on when you need them.
4. I then looked for things that were running but were not needed by anything ( google maps are used by a few apps so dont disable it haha) I used Uninstaller for root users to get rid of some things.
After all these steps my battery life went WAY up. I have been doing the same thing on my Xoom now and my batt lasts the same at 1.5 as it did at 1.
I still get VERY respectable battery life at 1.5ghz, I can easily get through the day with normal usage. Yesterday night in fact, I left the house with maybe 75% battery life, used my tablet quite a lot throughout the evening(left the house around 9, went to sleep around 1am) and used it all morning basically constantly from 7am to around noon and came home with 9% battery left.
No problems here either. Woke up around 8:30 yesterday and used it all day sometimes pretty heavy. Finally had to plug it in around 6:30. I'm home all day with a broken hip and femur, so I've been putting it through the paces. Running @ 1.5ghz with interactive gov.
Chris
+1 on 1.5GHz having little effect on battery life. I didn't have to change anything else, either.
thats all great to hear! I suppose ill start looking into rooting my wifi xoom tomorrow then. Thanks for the help!
Im very happy with the battery life on this thing. I expected 4 hours max after a few weeks of use/charges. I never thought that it would keep up with anything Apple, Lets face it.. Apple knows how to make stuff run forever. But I was plesently suprised. Xoom +1000
yeah, the battery is good, but i won't know any damage to the cpu when overclocked ?
I wouldn't worry about any CPU damage- too many people have reported success (and no reports of failure).
Anyone else notice with the tiamat kernel that their xoom becomes very unstable overclocked at 1.5 using setCPU? Mine was essentially a soft brick at 1.5 constant rebooting and never able get pass the unlock screen, I had to rewipe with bootloader. I can do 1.2 no problem but don't even want to try going higher.
All of our chips have variations, so the overclock isn't universally guaranteed. That being said, I've been using the Tiamat kernel @1.5GHz since it was released with no problems.
Should have stated that mine is the wifi model, but yea thanks for info.
Here was that post I was looking for on this stuff. http://forum.xda-developers.com/forumdisplay.php?f=946
Hey Guys,
i'm using the newest Matr1x Kernel, v11.0, CFS
and NSCollab 1.0.60 with my Nexus S.
CPU govenor is Lazy, i/o sheduler is deadline. Deep Idle is on.
Min CPU is 100 MHz, Max is 800 MHz, standard voltage.
13 h of usage, 8 % battery left. How can i improve?
I wouldn't consider my usage of the phone as heavy, screen is off quite often, especially at work. At work i'm writing some texts, browse a little bit on facebook, write some **** on whatsapp. Phone ist mostly off, i mostly respond to messages i get.
After work i browse some, play some games (Zenonia at the moment ), download something on wifi etc. Not too much in my opinion. Still battery quite sucks.
So my questions are:
1. Why is my battery life that bad? Phone is 1 week old, so battery shouldnt be broken...
2. I would like to know, if anyone can tell me about voltages? I would like to reduce voltages, but i'm a nooby and don't want to "test" it, cause i don't want to break the phone
Can anyone tell me, how much i can reduce arm voltage/int voltage? I'm speaking of my 100 MHz/800Mhz setting, it's still quite fast and i want better battery life, i think reducing voltages could help.
I'm open to any suggestion about getting a better battery life at best i would like the nexus to live 2 day without charges, with medium usage, if that is even possible.
cheers
All you can do is TEST there is NO one size fits all
but generally you can go about -25 across the board .. someone with more knowledge than me can correct me if i'm wrong =]
i get +26 hours easily on moderate to heavy use but my roms don't last for more than 10 hours
Thanks for your answer.
Does anyone else have any idea about the quite bad battery life?
I forgot to mention that i use Go Launcher Ex with a Touchwiz 4 Theme and the Go Keyboard, but i don't think they suck up all the energy :/
pisses me off quite a bit, 26h+ with moderate to heavy usage would be a dream!
Like it's now i need to charge it every day, and on weekend twice, once before i go, and over night (well while i sleep, doesnt need to be night

come on , be happy with what you have
i even have to use 2 batteries if in heave use !
try set display on auto-change or medium brilliantness
peronally , i think display is taking away more juice besides CPU...
kill GPS BT 2G/3G WIFI when you don't need them , specially GPS
and if you are not in hurry , use 2G data connection instead of 3G, because 3G took double even trouble juice then 2G
also , maybe some applications running at high CPU usage background , but i think this is highly unlikely
forgot to mention , also kill NFC

Hey, Thanks for you answer.
I forgot to mention.
Wifi and GPS are off, only turning it on if i need it(and that's rare). NFC is always off, i don't need it. Brightness is off auto-change and instead on the lowest value i can chose in the settings (still bright enough)
I'm checking RAM and CPU usage from time to time, so there shouldn't be the problem. Well i have 3g on all the time, but still, even then shouldn't i be able to get 20h+ or so?
What i also forgot to mention, i've the SLCD, the i9023 version. I know it has higher battery usage because of the display, but well, i think 13h is a bit low.
@polobunny: thanks, i will look into it

When i got my phone, the battery sucked. But after a week or so after some battery cycles it got better. So i advice you just to wait.
I don't use auto brightness, No auto sync but i have data always tuned on. I am able to get 10-20 hours with moderate usage.

no really ,my phone is i9023 as well , by the way , it's Super Clear LCD , SLCD is other thing of SONY.
SA screen only saves power when it is on dark color such as black , grey etc, when it is on white color , it takes juices same as(even more ? don't know for sure) Super Clear LCD , this has no different ,also you may noticed that default wall paper of Nexus S is dark color , that's why
back the time when i was using stock , i could easy hang on a day , but ever since i change to MIUI and brought second battery ... i have to use second battery on MIUI if my usage is same as the time i was using stock

about 3G ,
i have some power saver like applications , which have function of estimated work time
it shows , at this moment , 59% battery = 3G internet 1 hour and 39 minutes ,
other one shows 2 hours and 12 minutes
there may be some variants but ... you know , 59% power only last about 2 hours of 3G ...

you should have try stock first , because in my opinion , stock has longest battery life

I used stock for the first week, it wasn't better imho, atleast that's what my feeling says didn't look at the actual times i lasts with stock :O
but feels better with nscollab
About the display, thought SLCD was short for Super Clear LCD, well atleast you got what i meant
I thought about power saving apps too, wouldn't be bad if phone does only 2g if the screen is off etc, but first i wanted to get a good rom/kernel and settings
i think i will try ICS stock rom if its out, look if that gets me a better battery life, or then flash around till i'm satisfied
I have a Nexus S with CM7.1 and I am using the Glados Kernel v1.10 BFS.... I have my clock speed from 100-1000 on conservative... my questions are, what does this do? How do I do it? And how much battery life can I usually save? I searched it up, and I haven't really found too much stuff in depth. Thanks

I'm not sure anyone's even done any extensive testing, but I can tell you that kernels such as the Trinity SEUV kernel have a serious increase in batt life.
I'm talking 8+ hrs extra probably, at least. Now each person is different, so light users like myself will benefit more, but the difference is definitely noticeable.
That being said, it depends on the kernel you use, and how often you use your phone.

In the building I go to school in has nearly no service. I get edge at most when I find a spot, I had GPS on, brightness mid and all the same clock speeds.... my Vibrant got more battery life with the same clock speed on CM7, I had 27 when I left, I usually get 60something on my Vibrant. So what should I do, and how can I underclothing my device using setcpu?

unvervolting , as you can see from this word , under --- voltage
battery output juice to hardware such as CPU , screen , antenna ... etc
let me make an exemple , let's assume one battery has "1500" juice , if you output 50 juices per hour , then you can last about 30 hours , follow me ?
unvervolting reduces this output juice , let's say , down to 45 juice (you can not reduce too much due to stability and something like that) , then you battery can last about 33.33 hours , this additional 3.33 hours comparing to 30 hours , is extra battery life you got by undervolting .
of course this is not exactly how it works , but more or less, i think you can take the idea of it.
duration of your battery is very much depending on your usage.
3G data connection and GPS are battery killer , i have brainmaster's MIUI + franco kernel , 100% battery = 2 hours 3G data = 1.5 hours GPS navagation.

At what level should I start undervolting? I have it at 800mhz with 1125MV on lazy, is that fine to start with? I keep rising it each time it crashes on me( I started from 1025, worked my way up when I got random freezes). Do you recommend another kernel or something? I want the most power with the most performance. I heard Trinity was good but I may need to revert back to stock because the thread advised me to flash from stock for the most promising experience.

Here are my settings, once again, good starting point.
http://forum.xda-developers.com/showpost.php?p=19258876&postcount=1889
Some users reported that they had to bump 100 and 200MHz to 900mv and 400MHz to 950mv. To each their own, we all have different phones.
i have been doing affect of various variables including uv on battery life...
by changing one variable at the time..
in my testin.. undervolting actually made battery drain worse...

I'm sorry, but I fail to see where exactly you've proven that undervolting gives a higher battery drain in those tests.
Your methodology isn't scientific enough, although decently documented you have different usage patterns depending on the day. Sometimes you're playing a game and browsing the internet, others you're just idling all day.
On the undervolt test with Franco 25112011 kernel, your undervolt isn't even stable, leading to a reboot during a game and a battery stats "bug". Your screen was on 26 minutes more. Just the fact your undervolt isn't stable will make your battery drain faster. There's not only reboots and force closes as symptoms to an unstable undervolt.
The good way to test it would be by using a much more controlled environment and test patterns. Airplane mode can be used so as not to suffer from a bad reception or receive text messages/calls, a task (or multiple tasks) can be ran for a very specific amount of time, no user input other than starting the task and stopping the task should be done and the undervolt should be deemed stable.
Anyway, I can and will vouch for undervolting components, whether on a smartphone or a computer. I'm sure Trinity kernel users would agree too.

personally , i don't use undervolting , because it doesn't really effect too much on battery life
i didn't actually try , but i think undervolting could give you maximo extra few hours of battery life .
i'm using franco kernel , and 100 - 1000 with lazy governor
you minim should be 100 , 800 is not necessary
and for 1 GHz CPU , handle normal processing is enough
and i do think , that screen takes more juices than CPU ...
----------------------------------
i suggest you should try my way , buy an extra battery piece , then you won't worry about battery life any more ...
like me , i have to use phone very carefully back the time i didn't have second battery , sometimes i got out home about 8:00 AM ,and got back like 8:00 PM , when i back home , battery is nearly dead ... less than 10% .... = =
but now , i have second battery , i can use my phone whatever and whenever i want ...
i am in Spain , battery cost me 8 euros , if you can't find Nexus S battery , you can also buy Samsung i900's battery.
watch out , i900 , not i9000 , it's same battery , can be pluged-in in battery slot.
so , why did you waste days and days to search , to test , to set , to ask in order to get more battery if you can solve this problem with only 8 euors ???
but ... for real , these undervolting or overclock or underclock or what , does give you , hmm , how to say ? sense of fufillment , it's kinda good ^^
Some people enjoy travelling light, not having extra peripherals in their pockets and such. I already have enough stuff with my phone, keys and money clip without wanting to bring a battery somewhere in my dressy pants.
I read somewhere (and i think it was in this forum) that for the Nexus S the profile in SetCPU should be ondemand or conservative. I'm running Koush's Alpha 12, SetCPU "ondemand" and JuiceDefender Ultimate on "balanced". I've been on that for a week or so. I think the battery life is better than what i had running stock. I'm okay when the phone can make it through a day (like 16 hours) with normal use. I charge it at night anyway.

well , i think it depends on what kernel you use
some kernel's author would suggest what's best for his kernel.
also juicedefener or something , it's most likely by automatically shut down your unnecessary functions like GPS BT WIFI 2G/3G ...etc in order to save battery life.
i have been trying some of them , doesn't gimme much effect , probably it's just psychologic effect, you know , people would see what they want to see , also i have seen one application (Antutu something , i don't remember exact name) that reduces power output to hardware in order to save battery life , i think only that kinda applications can acutally save power...

it depends , look over your older kernel isntall zip file , check out if they put any files in directions (/system/lib , /system/modules , /system/vendor ...etc) , if so , delete them manually or check your new kernel zip file if it will overwrite the same named file ,in that case you don't have to detele these same named file because they will automatically be overwritten, otheriwse you do have to delete thoes file which won't be deleted or overwritten automatically.
...
i always just directly flash it ... if comes problem i just reinstall the ROM in order to get clean system and then flash the kernel.
some kernel like GLADOS and FRANCO has script to clear older files
but , anyway , back up before install any thing that could effect on system.

Yeah I just did that and it broke the wifi. I went to factory settings and installed Trinity, going through my normal routine tomorrow and going to see how long the battery life goes, apparently the performance is great at 880mhz and the voltage is pretty low.

I sometimes have a dress shirt or a polo with an additional pocket. Nevertheless I like to travel light, buying a second battery, while a good idea, is a poor solution to an unoptimized system.
too much undervolting can and will cause more battery drain. there is a fine line that can be crossed from battery savings to battery loss. after a certain point, the phone will end up working harder to get where/what it needs because there isnt enough voltage, leading to the loss.

Yeah I just did that and it broke the wifi. I went to factory settings and installed Trinity, going through my normal routine tomorrow and going to see how long the battery life goes, apparently the performance is great at 880mhz and the voltage is pretty low.

this minim is for screen luck status , when you are using your phone , system/CPU will automatically change it to adapt your processing , but when you screen is off , CPU should be running at minim in order to save juices
Ive been using Lithium v1.2.1 and recently flashed to 1.3 and i have been experiencing worse battery life than i had on the stock rom...any roms any of you have used that have outstanding battery life?

give it a few charge cycles. often the battery stats are just screwed up after a new rom. If it is still bad in a few days, then something may be wrong.

Okay, so I've been running Lithium v1.3 for several weeks now, and even with an added overclock and other tweaks, I still have pretty darn good battery life with moderate to heavy usage. I can get a full day's charge running at 1.25 GHz and emailing/texting/calling/gaming throughout the day. Just updating concerns from the OP with my own experiences while running this awesome rom! :good:

you haven't mentioned how many hrs you got in stock or how much less you getting in other ROMs
I am using stock ROM, 55% is enuf for me to go 12hrs which includes 4hrs of whatsapp, 2-3 hrs of gaming, continous gprs usage, 2 hrs of wifi tethering . a fullcharge once gave me 24hrs plus... I am very happy with the stock ROM

do u have a extended battery or have underclock ur processor ....cause seriously i doubt thats even a possible figure lol with 1500mah battery my lg optimus one was running just 7 hours before it died.....with totally heavy usage
what game where u running ....was it some heavy game like nova ...dead space or small time killer??
cause when i play dead space for 2 hours my battery drip to 50% from 100% on stock rom with gprs on

no extended battery for me, i just bought the phone a week back. no extra accessories.. just stock ROM, stock phone and stock charger/battery.
the game i played for 2-2,5hrs was stick cricket, then i played Extreme Skating and Pro Zombie Soccer for 30 min. Today i played Sims 3 for an hour and that took 10% of my battery. I switched on Mobile Hotspot in my phone and used its GPRS on my laptop(tethered) for an hour, that also took 9-10%.
btw, my prev phone was an LG OP1 . Let me know if you want me to check anything else.

We use tekahuna's milestone overclock modules for overclocking.
Changing the cpu speed involves echoing the desired table entry into the /proc/overclock/mpu_opps entry as root.
ie:
Code:
echo 3 1250000000 1375000 > /proc/overclock/mpu_opps
3 would be cpu slot 3 (3 is the highest on the atrix 2 typically set to 1ghz)
1250000000 is the desired frequency in hertz (1250 with six more zeroes at the end)
and 1375000 is the desired voltage in microvolts (1.375v). Tekahuna has said that 1.4v is the highest that these modules can push this. In my experience, that's not enough extra voltage to make a big difference in max overclock speed.
I recommend extensive testing of an overclock before you alter the init scripts to match. (well if you're using a rom with init built in)
Init.d support can be added to any rom by flashing this

As answersamir stated, it realty depends on the phone. I've clocked as high as 1.3GHz stably but don't really need that high of a clock speed, so I scaled back to 1.25GHz with underclock at 240MHz at echo 0. You'll just have to experiment without the echo 3 settings in the init.d folder making slow (100MHz) incremental jumps to see where your phone can run stable before random reboots or freezing occurs... after changing settings, reboot each time, and run for a while at the new clock speed to test.

use Battery Monitor Widget, charge the phone till you see 100% in that app, A2 shows charge in multiples of 10, so 100% in A2 battery means it reached 95%. Via the BMW app, you can add a widget to your homescreen in counts of 1% so you will see real battery %. Also it will show mAh, so when you charge untill it reaches 100% or 1740/1740mAh then only stop charging. You can see battery graphs and all that.
Hope yours is set to Settings->Battery $ data manager ->Battery mode -> Night-tiime saver
cos mine is
also via that app, it shows for me voltage of ~4113mV and a decent temperature of 33-35 degree celcius while charging.
Install the app and let us know the details. Also hope you are using the motorola charger and connecting it directly other than via usb->pc

Here's a simple step-by-step for overclocking:
Open Root Explorer or download HERE
Navigate to: system>etc>init.d then select the Oc3 with Text Editor
Find the echo 3 value that reads: echo 3 1125000000 61 > /proc/overclock/mpu_opps
Then, using the text editor in Root Explorer, change the echo 3 value from 1125000000 to *up to 1200000000 or even higher. (see note below!)
Hit the "back button" and Root Explorer will ask you to save changes. Confirm the changes, and reboot.
After rebooting, open SetCPU and you will see your changes there.
*You can experiment with your clock speed, and a good rule of thumb is to bump up slowly, rather than making large jumps all at once. Start by going from 1125 to 1150 and reboot. Then, if all is well and you've ran at this higher clock speed for a good 5 to 10 minutes, do the above listed process again and go from 1150 to 1175, and so on until you reach your highest stable overclock speed.

You can also underclock in the same way, by changing the echo 0 values. I set mine to underclock to 240MHz at echo 0. Also, using SetCPU you can change the CPU mode (which, you probably already know) from mot_hotplug to performance to ondemand, etc. Experimenting with these settings can either improve or decrease your battery life with the new overclocked speed.
Also, check out THIS THREAD post by rdavisct that gives further explanation to the topic.

Hmm there a problem....there no oc3 file in init.d???
I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now. I don't want to touch the performance settings without knowing what I'm doing. Is there a way to change my performance settings to extend the battery life? Also has anybody played with a different kernel with CM 10 stable? Thanks

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.
Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.
Also turn off google now location settings if ur not using it. They are really hard on the battery.

Disable Google now and battery should be back to normal here is some pics. Cm10 default kernel,stock clocks, no UV, on demand governed, and deadline as scheduler

Thanks for the replies.
It seems to be my screen that is responsible for eating up my battery. Have had the phone disconnected from the charger for 4 hours now and all I've done is 20 min with screen time doing a little bit of texting and facebook and my charge is at 75. I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.
I used to be able to go all day with my phone with CM 9 and I even have the nexus battery.
Thank you for all your help
That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.
I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

I'm currently running the vanilla CM10
Turned off google now location access and set the govern to on demand early this morning and it is performing a little better most def.
I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.
Thanks for all the help people! Def the best forum by far on the web.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?
Learn more about the different governors and schedulers: http://forum.xda-developers.com/showthread.php?t=1950084
Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.
http://forum.xda-developers.com/showthread.php?t=1754473
I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.
so I should be able to run the 5 ICS radios I found eventho im running jb right?
