My G.Note does not use the 1.4Ghz

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

Did anyone manage to have 40hrs++ battery lifetime?

Dear People,
I am posting this out of big ENVY from my friend's story of his iPh*** 4 battery life with 40hrs ++ of usage (social network on, moderate usage, data always on, bla bla bla) and he still got 20% left of his battery!!!
I was just wondering did anyone managed to experience 40hrs ++ of battery lifetime? My best achievement with my nexus s battery life is
1 day 3 hrs with
MIUI Rom JB 2.8.17
Marmite Kernel 4.3
SmartassV2/deadline
100/1000
Automatic brightness on
Could we EVER achieved 40hrs ++ battery lifetime??? Since Iph*** 4 has practically same specs with Nexus S
It has 1Ghz procs, 512mb ram, 1500mah battery, bla bla bla
Any comments?

A very big advantage of the iphone is the very dim (to my opinion) screen backlight. If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

I've been getting pretty excellent battery life lately, will put up a screen shot but got almost 52hrs battery life with wifi and 3g on until it got to about 15% with about 2h 24m screen on time, although this was pretty light usage to be fair.
Using codename 3.3.2 with standard kernal, I turned NFC off and this seemed to help massively although I've also heard the new Maps app has solved some battery drain so not sure which has contributed the most.

52hrs?????? Cant wait for your screenshots man!

You may think the specs are the same, but the hw in the iPhone and power management is still superior. They get a push notification, even while the 3g radio is in idle and almost off (in which it saves more power). It's hard for Android to optimize the power management specially because of that many hardware variations, it's not only the CPU that counts.

Well, thats good to know, but since its the software differences (meaning coding and stuff), surely (i assume and hope) that we could also applied it (somehow) in our devices through tweaks, can we?

IMHO not much is possible since this is older hardware already and a question for how long will Google bother with it. It might be alot of work needed and you gain some insignificant amount of savings.
Would be nice to see some kind of power management tweaks in coming version of Android though.

well its halfly because android works differently and half way because of the hardware.
yes, the hardware is similar, but the nexus screen takes up more power, the processor is not very efficient, and nfc takes up power... also, the 3g radios are honestly HORRIBLE on the nexus s and that might have something to do with it.
but, the software side does make a major impact. iPhones do not multitask like android, which saves power on slower devices like the iphone 4. thats only half of it though, for instance, the iphone 4S has much worse battery life than the nexus s (by far). ROMs make a big difference also, I am very picky when choosing a ROM- if it doesnt have great battery life then I immediately replace it by another ROM that does.
I get on average about 16-20hours pretty consistantly if you are wondering, and I am OK with that as long as it makes it to the end of the day... I wake at 3:30 and normally it does. My advice is to experiment with different ROMs, I would suggest some, but I use an S 4G...

I don't really believe it. My friend has an iPhone and he uses it quit a bit and seems to have to keep it plugged in as much as I keep my phone. I think he said he usually gets about 8 hrs out of it. And the screen is pretty dull compared to mine so that might make a difference to

The iPhone screen is a lot smaller too and that's a big tradeoff.
I always get a chuckle at the iHerd people I see on the bus holding their tiny screen 6 inches in front of their face so they can read it.
If battery life is really a concern get a couple of spare batteries and a charger.

Lasting 40+ hours is easy if you don't use the phone much...
The screenshot was taken on a long weekend a while ago. I was busy during the weekend and didn't use my phone much apart from listening to music for no more than 2 hours.

[TIP] Increase battery life on JB 4.1.2

Hey guys
We all have been facing a lot of problems regarding Battery life in JB 4.1.2(Updates with the same changelist )
Here's an app i found which provides a great walkaround from the battery drain but with certain restrictions in device performance - DEEP SLEEP BATTERY SAVER
I used this app when im travelling when syncing emails and stuff doesnt really matter or i can do with a 30 min or so sync interval
Here's the link for the original thread on xda
http://forum.xda-developers.com/showthread.php?t=2030696
How Deep sleep Battery Saver works
Deepsleep battery saver constantly puts the device to deepsleep mode while screen off. During deepsleep mode, Wifi, 3G are turned off, background apps are stopped. Therefore, most apps are not working, including Facebook, Google Service, etc,. It then constantly wakes up in order to download email, sync Facebook status, etc, which is defined by deepsleep frequency and woke up duration
By constantly put device into deepsleep mode, we will save battery life due to no Internet connection, and therefore most of network-based apps, such as Facebook, Gmail will not work.
Caution: during deepsleep mode on, this app may disrupt your normal activities, such as your email notification comes with larger delay.
In advanced mode, you can customize more parameters, including day/night settings, active period, screen timeout, sync strategy, ignored apps, etc,.
Thank me if i helped

Cool thanks! But I'd rather charge my phone in the middle of the day (which I don't have to do even with the battery drain that 4.1.2 brought) than have it turning off radios and not getting calls, messages and notifications. If you disable those, then what's the point of having a totally awesome specked out Note 2! But to each his own ^.^

It does not turn off the radio. Have you even read the thread ? jeezz....stop assuming...

It doesn't turn off the radio, it just delays the sync internal for email, the rest of the functions remain the same

You call that increased battery life?
Sent from my GT-N7100 using xda app-developers app

Yeah that is increased battery life with proper usage, sync was on all the time and i used wifi whenever available with intense screen usage not just low light reading, brightness was around 50-75%
Sent from my GT-N7100 using xda app-developers app

Deep Sleep was/is not a problem on 4.1.2, rather it's the excessive drainage when you are actually using the device, that is lesser screen on time than 4.1.1. Deep Sleep works pretty fine on both ROMs.
'Swyped' from my GT-N7100

It's nice if you think you see a difference, but I think you would have the same effect with juice defender or even tasker with a sync and connectivity schedule. Our device has a much more effective deep sleep than older phones already, so I think it's only the sync schedule that's making an impact.
Unless the app prevents wakelocks for some reason, though that wouldn't really make the phone very stable.

TIP Increase battery life on JB 4.1.2
You could down the CPU to 1.4 MHz clocks, it is worth 3 hours extra endurance.

I'm beginning to think that wifi is the big drainer. On previous version and previous phones, I would leave wifi on all the time. On 4.1.2 though, I'm finding that 3G is less of a drain with screen off that wifi is.
Which is a bit strange to be honest..

Wifi does seem to be draining a lot of battery life in 4.1.2 as compared to 4.1.1
But there is another thing i noticed, the screen brightness at the lowest setting has dramatically increased from what it was in 4.1.1, i remember a guy checked the max brightness and found it to be around 300% of 4.1.1
Sent from my GT-N7100 using xda app-developers app

Many apps prevent the device going into proper deep sleep and cause partial wakelocks or so, I've tried other apps too like battery saver pro and juice defender but i found this one to be the best

I find that my phone "wakes up" much less often on 3G rather than wifi.
This is surely a bug and I hope Samsung sort it out. This is my first Samsung device after 5 HTC phones stretching back to the WinMo days and 1 iPhone. The uglyness of Touchwiz in comparision to Sense, and the idiotic choice to use the internal storage as a "fake" SDcard are frustrating to say the least. But this uneccessary battery drain on 4.1.2 is a constant pain in the ass and needs to be sorted ASAP.

[Q] battery life comparison exynos vs snapdragon?

Are there any comparisons of the two cpus available on the s4 when it comes to battery life? Thats the only reason for me to try to get an exynos version if its shows to be better in that respect.

Yeah, that's a good question I want to know the answer too, there are many people having testing devices but they are too hungry about testing the damn processor and gpu instead testing properly the battery life. -_-

With wich cpu? Also no comparison to the other version mentioned here.

I'm not convinced, even with S3 you can spend all the battery juice in 3 hours if you want. To do a proper test you need to leave the device doing the same job like an Snapdragon S4 during the same time.

Thaty what one hears, yes.
However I would like some actual test reports - for instance how long does the phone last for web browsing, for video playback and on standby?
I would like to see actual numbers.
As for the screen:
It is said to use 25% less power compared to previous amoled display generations. However that 25% value is something we have to trust samsung on I think, at least I have not seen any actual tests on power consuption of the display alone and it's probably not easy to test.
The way they have managed the display to consume less power is to use use phosphorescent instead of fluorescent green diodes, which use way less power. Until now they could not produce the green ones with an acceptable lifetime. The red ones have already been phosphorescent, and the blue one are still fluorescent since they are hardest to produce.

This. This so many times over.
So many people are parroting the "Exynos will have better battery life" thing but this really remains to be seen.
If the better battery life is in exchange for crippled A7 performance at inconvenient moments then it's useless. If better battery life isn't available for when you're using intensive apps then it's also useless.

[Q] Do you guys see any difference by using Power Saving mode?

I see no differences or noticed any improvements by using power saving mode. I feel like I get better results without using power saving mode than using it. Do you guys see any differences?

There's probably a small difference, because it underclocks slightly and removes animations.

Not even a small difference for me. I get 1% drop every 6 mins either way (With or without power saving mode). I'm not sure if I'm supposed to check the "Restrict Background Data" as well for it to work better.
