Hi all, I have been seeing some screenshots that other people post about the sleep issue and there is one major difference from mine.
Note sure why, but my Note does not use the 1.4ghz and 1ghz frequencies. I am running a stock gingerbread unrooted ROM.
Is everything alright? I do play some intensive games on it, so I am not sure why it doesn't use its full power.
Please see the screenshot attached.

Wow you are honestly complaining why your phone doesn't use 1400 MHz and I'm here dreading why my note keeps using 1400 MHz draining my battery
Sent from my GT-N7000 using xda premium
Thats actually a good thing, higher frequencies = greater battery drain. My note also rarely jumps over 800Mhz even though i play intensive games like modern combat 3
Discovered after each reset or power up, Note deep sleep and processor speed unstable.
Mostly mine run on 200Mhz, rarely above 500Mhz.

Do you have System Power Saving mode on? That mode can underclock the processor to save power, so if you're using it try switching it off.
I can see from screen shot power saving mode is enabled. Please disable then it will work.
Sent from my GT-N7000 using xda premium
Yep, that is indeed the problem. The sign for the power saving mode can be seen. Deactivating it should resolve your problem.

Thank you all. I have completely forgot about it, as I have turned it on after I got it.
I'll try turning it off just to see if it will solve the issue.
I have a follow up question. Why does my phone take so long to get into deep sleep? In the morning when I wake up it is consuming about 6mah of power just after I switch the screen on, but usually it uses about 60mah with all but BT turned on.
Is this normal? What values do you get?

There is no provision for accurate mAh readings on Exynos devices - the function simply doesn't exist unlike in HTC phones. Apps like CurrentWidget and Battery Monitor Widget can only estimate mAh usage readings, so that would probably explain your puzzling values.
The way to tell whether your Note is going into deep sleep is to use CPUSpy - the deep sleep timer should go up if you turn the screen off in CPUSpy, wait some time, turn the screen on and refresh from the CPUSpy menu. On Gingerbread, there also is the customary lag coming out of deep sleep between hitting power button and the screen coming on.
Looking at your screenshot, your deep sleep time doesn't look too unusual. Remember also that the phone does not go into Deep Sleep when charging the battery.

i don't think this is correct.. im on rooted GB stock and i see my note clocks 1400 ghz..
this probably depends on what games or apps you use... it just doesn't make any sense to put an O/S that is not designed to use the max cpu speed of the device

Not so sure about the wifi part. I've compared the phone idling on 3G vs. idling on wifi and with wifi there's definitely more power draw. Confirmed it with System Panel, the CPU is pegged at around 10% usage while idling with wifi vs. about 1% when idling on 3G.
This has been consistent with all my other android phones too (Nexus One, Vibrant, MT4G)

You're right, wifi uses more power than 3G, and they both use more power than 2G. When idling I'd definitely want to sit on 2G if anything. When you actually need an internet connection though, wifi and 3G will be more efficient. They'll use more power but will download much faster to make up for it.
Saving power is the same for almost all android devices:
1) turn off mobile network when not in use
2) turn off wifi when not in use
3) turn off gps
4) turn off automatic syns( if you dont use them)
5) brightness set to low
6) turn off live wallpapers
7) use a black wallpaper
8) turn off haptic feedbacks
9) set screen time out to a smaller interval.
all these steps might help you but it kind of takes away the charm of the phone imho.

It's definitely the opposite of that, its counter intuitive but WiFi uses significantly less battery life over 3g. I can post some numbers when I get home tonight if anyone's interested. But a good test is leave your phone on WiFi all night, then repeat on 3g and see the enormous difference. Better yet just look at the official Google specs, web browsing time is always higher on WiFi.
I did some real nice graphing of current draw at 2 second sample rate comparing various tasks which is What I'll try to post later..

Bionix 1.2 @ stock speed, not the OC-ed version
it's stable, fast, and battery good
i have my data on all the time sync-ing every 30min
and 1 battery can last me a full day without plugging it in
Wifi automatically sleeps if your phone is idle for so long, therefore saving battery. 3g absolutely kills my battery so I have mobile data disabled when not using it. Works well for me. Also screen brightness on 0% using an app works good.

i tried with and without setCPU, and the difference in power saving was marginal
so i removed it.
it probably gave me an extra hour, but there is a bug with setCPU when picking up calls, it gets staticky until the CPU is at 800 Mhz or more
so with all that i mind, i decided to remove it

True, change the WiFi sleep policy to "never" to avoid this and extra battery savings.
I've been getting the best with CM7 so far, but I think all the roms that are about the same as long as you don't overclock them.
Use a black static wallpaper, low brightness, and get the black-themed MMS and Gmail apps from the Themes/Applications forum.
I can get well through my work day. Usually have 2+ hours of display time on and about 16 hours off the charger by the time I plug in at night with still 20-30% left. Depends on my reception in the day as well, which is pretty bad at work, so I think I'd have 30-35% if my reception at work was good.

Agreed on all points except for GPS. Since it's an on-demand service, leaving it on makes little to no impact on battery life. The phone only utilizes the GPS connection when an app calls for it and saves you the time of having to toggle it every time you need it. Just leave it on.

An active WiFi connection uses a lot less than an active 3g connection because the connection already exists and the data transfers faster.
An idle 3g connection uses significantly less energy than an idle WiFi connection. If you aren't using or connected to WiFi, turn it off. Set the WiFi sleep mode to sleep when the screen is off.
On my Bell Atrix, I've found that in every build of Gingerbread I've tried (both the AT&T and Orange France versions), my CPU never cycles down from 1 GHz. On Froyo, it would change depending on usage, but with Gingerbread, it's always pegged on max. According to SystemPanel app, approximately 40% of the CPU is constantly utilized by "System" non-stop. This was not the case with Froyo.
I wonder if this ties in with the entry in the battery usage list which shows X as being among the top two users of battery. The CPU total for X is almost the same as the time the phone has been awake.
Has anyone else experienced this? I know there have been a lot of people complaining about the poor battery life on Gingerbread (and I'm one of them), but now I'm wondering if it has to do with "Service" and the mysterious X constantly using the CPU in the background.

I had the same problem, when you delete all data from fastboot (fastboot-w), install 2.3.4 gingerbread returned and the battery lasts me about the same as the stock 2.1.1 FR. (taking into account that spends more battery 2.3.4). now I have the Orange Radio 2.3.4 with kernel faux123 0.100.00R. sorry for my English
I've run fastboot -w, and used CWM to clear data/cache both before installing ROMs and after installing ROMs, and none of that made a difference. BUT last night I installed kennethpenn's Beta 4, and for the first time, my CPU frequencies were properly scaling, and System was not taking up 40%. Since then, I've wiped data/cache and tried different kernels and different ROMs, and all of them are working. It's almost as though kennethpenn's ROM installed something that wasn't there previously and is persisting through wipes, and ROM/kernel installations. Is that even possible?
freeze your bloat.
use setcpu for system profiles.
problem solved.
For me it was X server running in background and taking 40-50% of cpu. I had to move it because there was no other solution.

I didn't have to do this with the Froyo builds and I still had excellent battery life (2-3 days). if I go back to 1.8.3 I still have excellent battery life. And that's with Corporate Sync, Gmail push, and Twitter and Facebook in Blur's Social Networking.
There is something in the leaked Gingerbread roms that eats batteries for lunch.

I'm also on a bell Atrix with 2.3.4 Orange. I've actually never seen this X process that some people talk about? I don't see it anywhere in my battery usage. My top 2 are almost always display and phone idle. I wonder whether you guys are using a setting or app that I'm not. That said, I'm not getting great battery life either. 10 hours and my phone dies.

That's pretty much what I was getting as well. X was always second to display in terms of battery usage, and it seemed to be using the CPU constantly whenever the phone was awake. I'm not sure what to make of it, what with some people seeing it and some people not. All I know is that after I tried kennethpenn's ROM, X disappeared, and my CPU seems not to be occupied nonstop. Since then I've wiped my phone and installed the Ninja ROM and faux's stock international kernel, and my phone continues to function without X eating up the CPU. This was the exactly same setup that, prior to kennethpenn's ROM, was suffering from constant high CPU usage. No idea what changed it, but now things *seem* to be operating normally and my battery is much improved.
I solved it renaming "/etc/X11" to "/etc/X11.bkp". So... X process magically disappeared!!!

Open setcpu. Go to profiles. Then quit and go back in to setcpu and it should stick. Don't know why. I'm going to try a profile to keep it at 1100 like temp over 0. Who knows.
Sent from my MB860 using Tapatalk
Funny. I opened setcpu and it was back at 1300, so my solution is moot. I did just set a profile if battery is below 101% then scale to 1100 low priority (40)
Sent from my MB860 using Tapatalk
I don't know what the deal is. Set cpu tells me the clock is set to 1100. Which matches cm7 settings which also matches system panel. But watching the cpu speed in setcpu it will go to 1300. So yeah. Back to the drawing board.
Sent from my MB860 using Tapatalk
Bear with me. Not spamming. Here's my deal. Most people's governors are greyed out. Mine is not. Tasker, system monitor show it which then allows setcpu to show it. If I'm on powersave the clock will not stick to my setting of 1100. If I set it to performance. It sticks. Any one confirm or deny?
Sent from my MB860 using Tapatalk
I was seeing the same thing until I made a profile for Battery < 101 max at 1000 and a priority of 80%. Now every time I open setcpu he cpu maxes as 1000.
Indeed.. atrix with stock kernel runs all the time at high freqs..
with faux kernel, is at lowest value, so we save battery.
does it have a governor enabled by default or something?
whatever he did, its pretty good!
Imagine that with undervolt..
i just noticed this morning after unplugging my note that even though my note is going into deep sleep the battery drain is still way too much as compared to the previous day...
i checked cpuspy and at first didn't register anything odd except that it goes into deep sleep.. after a second glance only then i realized that instead of running at 200mhz my note was running at 1000mhz during charge..
has anyone here experienced this before?? although i noticed that it seems to be a lot snappier now
i just can't help but worry what lasting damage it may be doing to the processor... and the fact that even though it goes into deep sleep i'm losing about 5% of juice for every 15-20 mins.

ANy new apps that u installed recently ?
Normally , rogue process is going to call an abnormal battery drain ,,,download some sort of process,app moniter and see which process is running and taking most of the CPU time......My guess is that it has to be one of the apps that you have installed or started which is causing this
That was what I thought initially but I don't remember installing anything these past few days as I just froze a few bloatware and was monitoring the device for any issues.
The last thing I remember changing was some setting under the development concerning background process.
Hmmmn. Maybe I'll put it back and see.

i did a hard reset by turning off and pulling the battery for a few minutes... still the same although the note still goes into deep sleep but hardly uses other cpu speeds except for 1000mhz...
i tried freezing some of my apps and games, those which i suspect might have required 1000mhz to run but still the same...
i guess i'll just have to wait and see for a little while if this changes...
i'm now thinking of reverting back to GB... since the battery drain for ICS is such a let down and with this problem... i'll give it a couple more days
what ROM are you running?
anyway something in the governor seems to have changed ,your case seems to be a performance governor.
try installing set cpu and set minimum to 200 ,max to 1400 ,and the governor to "on demand"
should fix things for you

Power saving mode will only have a a big impact if you do a lot of web browsing.

I don't think CPU downclocking needs to slow down things - the HTC One runs at a lower clock and runs smoother.

It runs smoother only on UI tasks (and even the difference here is unnoticeable).
Most of your time you using apps, browsing the web, taking photos, making phone calls and messaging. In this tasks, the S4 runs as smooth (and even better in some) as the HTC one.
For the OP, I didn't noticed any change in responsiveness when using power saving mode but the brightness is lowered (about 20%).
If you need more juice out of the battery it is indeed a great option and you won't notice any difference but the lower brightness.

Most of your time you using apps, browsing the web, taking photos, making phone calls and messaging. In this tasks, the S4 runs as smooth (and even better in some) as the HTC one.
For the OP, I didn't noticed any change in responsiveness when using power saving mode but the brightness is lowered (about 20%).
If you need more juice out of the battery it is indeed a great option and you won't notice any difference but the lower brightness.

See my link for power saving brightness measurements.
Your statement on performance is false. UI (such as OS menus) are indeed slower and display a level of lag. BUT other tasks such as opening the gallery or dialer and web browsing in general (in spite of not having text reflow for custom zoom in the browser)suffer a significan amount of lag. Changing the launcher only improves the home screen fluiditity.
The only area where I see better performance at the moment is for some games. To me it seems 4.2.2 release was rushed and 4.2.1 runs smoother, which could explain the horrible performance of the S4, so we will have to see how 4.2.2. behaves on the One. Many have reported that 4.2.2. has been plagued with bugs and lower (also battery) performance.
I havent notice any change in performance when I switch to Power Save Mode, but again, when I usually do it I don't run any heavy process. I dont know if its placebo or real improvement but my battery does seem to last longer when the phone is about to die and I switch to power save mode
Or do I have terrible battery life? It's really bugging me because I always have to charge it overnight and occasionally twice a day! I'm on CM10.1 and using KK's Next kernel. Airplane mode is always on and I only turn on WiFi when I surf. The brightness is always below a quarter. Most of the time it's at ~5% brightness. Is this normal?
Screen on time is 4hrs2mins

Terrible battery life indeed. We have a P-3100 with SIM card inserted, use data on 3.5G+/HSPA+ browsing for most of the screen on time, 65% brightness, 4-5Hour screen on time and I get around 4-5hours.
Stock 4.1.2 BTW

I think its the os' fault. As I can recall we have about the same battery capacity as the iPad but iDevices lasts much more longer. Even with the RAM consumption.

Yeah, I managed to squeeze out around 15 hours on my Mini (around 14 hours screen on), on Wifi browsing 10~, 2~ hours on Pdfs, 2 hour video, 1 hour music with screen off.
Brightness @ 55-60%? not entirly sure but somewhere around there.
That again, its fully data on Wifi and not 3G.
The Mini does seem to use RAM a lot more efficiently, It does run a like 2 task in the background and pauses the rest doesn't jerk up (99% jerk free).
Tab runs a huge ton of apps in the background without pausing intensive ups, it uses up RAM fairly heavily and jerks up a bit. I find myself constantly tapping on the multi-task menu killing background task dispite having 1GB<-Thats a touchwiz ROM btw haven't tried AOSP on that.
Besides that, Ti OMAP 4430 vs Apple A5 2nd Gen
Both Cortex A9 Dual Cores running at 1Ghz, Ti uses 45nm while the second gen uses 32nm (More power efficientcy)
Both have PowerVRs, Ti has a Single Core PowerVR SGX540 @ 304MHz Vs A5's Dual Core PowerVR SGX543MP2 @ 250Mhz/core
Overall, I believe it has more to do with Android's base. It is written on Java as a pose to C+ like iOS. Java needs its codes to be emulated on a virtual machine while iOS runs it nativly.
If Android can be coded in C+, It will take away CPU cycles and we could see a drynamic improvement in battery life, speed, literacy and closer CPU and GPU integration.

Its useless. Thats nothing more than toggle settings, brightness and killing background task(s)

Than the apps will start again, you kill them, they start again, you kill them and so on, and you wonder about battery life?

99% of user apps don't kill and start again automatically.
You are refering to system processes which I always leave alone.

guys ultimate juice defender is great it is know saving by battery at x1.88 this means almost the double

Mmh, you forgot the "free" apps, most of them start again in background to load adds.

Maybe you can try "Greenify" from market
I charge my p3100 2 hours more after full charging.. always use automatic brightness for good battery life of device

no offense but i dont like samsung's auto-brightness. ios's has better management regarding auto-adjusting the brightness.
im having a hard time looking at the tab outdoors. and im not really directing the screen into the sunlight.

That's pretty bad for the battery... Fully (as in FULL) charging the battery is not good for the long term.

I second "Greenify" suggestion. It has almost doubled my tablet and phone's standby time.
I had improved my battery life using old method such like for my HTC . No it work about 48 - 50 hours on medium use.

The tab stops feeding charge to the battery when it's full. Leaving it on the charger has no effect positive or negative

I believe its the kernel.

Do you suggest that it is better to keep plug the charger even though already full.
Is there a Charge and Discharge Counter or something like that, just like a notebook, that would shortened the battery lifetime?
In that case, it is okay then to let it charge over the night, right?
The one your describing is called charge-cycle. Every battery has one. Its better to fully drain your battery once in awhile so the cell on your battery wont solidify. Do it maybe monthly. On notebooks we can remove the battery, and use it plugged-in so it would not wear-out the battery fast. Plugging your device while the battery is still installed is different from no battery and plugged-in at all.
