I have no battery issue with ICS, even find it quite good but not sure if GB manages longer using time cause I bought Note and upgraded it immediately on to ICS :D.

Internet connections always active, as well as autosync.

The above usage was just a test, normally I always try to drain Note's battery before sleep so I can charge it fully the next morning. And after last night's felling asleep while leaving the screen on(about 2 hours), battery usage looked like this:

Samsung gave 7 MB update

Hi,

i just got 7mb update.. (samsung india)

will check bugs are fixed or not..
[Galaxy Note GT-N7000 General] faisal:
Since my last post, my phone dropped its battery performance and to test this out, I did step 5 again (waking it up before unplugging) and ... back to better performance again (73% at about 6 pm)
[Galaxy Note GT-N7000 General] inurb:
Today my phone died after 4rs of browsing with screen brightness on the lowest setting while connected to wifi. What the hell is wrong with ICS? I'm going back to gingerbread.

I shouldn't have to trick my phone with airplane mode and all this deep sleep crap in order to get close to what I was getting in gingerbread battery life wise.

Samsung **** the bed with ICS for note.
[Galaxy Note GT-N7000 General] Mc_CuLLa:
I always calibrate my battery which you need root for and i also run kingdroid v4.3 with speedmod which lasts around 12 hours
[Galaxy Note GT-N7000 General] dotslashbin:
Weird behaviour

I am also one victim to this "NOTE + ICS = battery disaster" problem. I am a person who didn't want to go on battery saving option for most of the day, and I refuse to turn off the 3G or WIFI, as I need my phone to be connected.

I managed to get by by doing the sleep mode -> power off -> power on -> turn off sleep mode routine, and was getting enough deep sleep with that. It was not the best battery performance, but I was able to handle that. However, just recently, things seem to have changed, it seems that I cannot go to deep sleep anymore. It always stays on 200 MHZ, even when I try to remove the battery ( which I do not intend to do often ).

I just found out now, that Nike+ Running app was consuming 90% of my battery, so I uninstalled it and will be observing this one from here on.

So, have you guys heard if there will be a coming patch / fix for this one? I am certainly hoping so.
[Galaxy Note GT-N7000 General] tdodd:
The LPY (German) ICS update has proved for me to be a disaster, repeatedly. I've installed it separately three times in total, with wiping and so on to start a clean state, and every time it has disappointed me and I have returned to Gingerbread. I made the upgrades both through Kies and OTA, but either way it sucks. Not sure if I tried PC Odin, but I'm beyond caring at this point.

More recently I tried the LQ2 (UK) ICS ROM, and that seemed to be significantly better - perfectly good enough for continued use it appeared.

However, itchy fingers got the better of me, so now I'm running the Paranoid Android custom ICS ROM v0.4a and that's working nicely too. I think I'll be staying with this ROM (or newer versions of it) for a while. :good:

So all in all I don't think ICS is the problem, but Samsung's first effort out the door for the Note (the LPY ROM) is, IMHO, a complete lemon and best avoided. More recent offerings may not be so bad. Hopefully, future offerings will be a whole lot better, maybe even without the inclusion of the free brick bug.
[Galaxy Note GT-N7000 General] Flaco05:
My Note goes to deep sleep just fine after following some of the suggestions here, but the battery consumption while awake is the killer. Why does routine usage itself consume so much battery in ICS relative to GB? I don't think this can be tweaked. Right? It seems that the only way of addressing this is through some kind of system update from Samsung....
[Galaxy Note GT-N7000 General] REVERSiN:
Ics uses both cpu cores unlike GB it's consumption is way less but infact gives less performance.

You can manage the proccesses and autorun to use less ram so this causes slower consumption of battery. Another thing is mermory management many tools can do that pick one and see difference, services.jar can be patched for better performance categorizing the priorities for system better.

At the end each step helps but of course its not an AOSP rom so keep in mind its not comparable.
[Galaxy Note GT-N7000 General] dotslashbin:
I am certainly hoping for the same. What sucks is that this is my first ever android phone, shifting from iphone LOL. So I guess its not such a good experience for me.

[Galaxy Note GT-N7000 General] JulyDerek:
Try rebooting your phone. Thats what works for me.
[Galaxy Note GT-N7000 General] tdodd:
And take it off the charger. It will never sleep while being charged. It will stick at 200Mhz all day long whilst power is supplied.
[Galaxy Note GT-N7000 General] kyrirhcp:
I have to say that with ICS i've had the best battery life any of my smartphones have ever had. I reflashed XEU 2.3.5 then updated OTA to ICS and my phone lasted 3 days on one charge with about 12% left on the end of the 3rd day (plus I had forgotten my 3G on for at least 10 hours). Once I was rooted I moved to speedmod kernel which absolutely thrashed my battery, I would lose 3% in the first 5 minutes of taking it off the charger.

It's definitely the best battery life I've had on the Note by far. On GB I would often need to plug it in at some stage during the day just to make sure I would have enough to last until I went to bed.

Also, coming from a HTC Flyer I think that perhaps I am just greatful to have a device that is actually mobile and not stuck to a power socket.
[Galaxy Note GT-N7000 General] nnick:
I had an OTA update to 4.0.4 for my Note. Curious if it solves the problem.
[Galaxy Note GT-N7000 General] Beards:
OTA??? Which ROM did you previously have?
[Galaxy Note GT-N7000 General] cka3o4nuk:
Rocketrom v7 +speedmod k3-7 + lastest modem give best battery life on ics.
[Galaxy Note GT-N7000 General] ryebuck:
I get a little less battery life with ICS, due to the removal of the easy way to adjust brightness by swiping the top of the screen left or right. Now it's so much more hassle to adjust brightness that I just keep it bright all the time.
[Galaxy Note GT-N7000 General] adicristea:
These two posts from the beginning of this thread were very helpful for me. The battery was draining really fast sometimes, I couldn't understand why it would go 2% in one hour and then 25% in a few minutes. Installing the two apps Tiny Wiz recommended it's a life (or battery) saver.

Thank you!!

PS. I have ICS 4.0.3 COA (Cosmote Romania) on my Note.
[Galaxy Note GT-N7000 General] nnick:
See below for the old ROM, the new one and CPU Spy. For me it seems to have solved the problem, but I'll keep monitoring it.
[Galaxy Note GT-N7000 General] Beards:
Thanks.... No OTA for me and yes you are ahead of my ROM.

Hey did this update solved all problems?

Battery issue in NOTE

I am having battery issues and its draining too quickly i charged it to 100% and just have a look how quickly its discharging..i havn't switched on my bluetooth since two days and its showing that some % of battery is used by it how come it is possible? Attaching a screenshot plz help guyz please..:(
[Galaxy Note GT-N7000 General] garytube:
I had the same problem. It's caused by an busy box update! Try re-installing busybox (in app) . When you open busybox you will see that the installtion path can not be detected.

How to fix:

I assume you rooted your device with the temporary CWM method. Simply unroot your device. Then reboot and root again. Done.

How to check if the bug is still active:

Go to

Settings - developers options - show CPU threads

You will the in the upper right corner all active threads. I if there is an "sh" thread you got the bug. (it could be a different thread deepening on the busybox version. On my screenshot its caused by "sh")

Let me know if could helped you

Did anyone ever consider that it could be Charger related,today I used my HD2"s charger it took over 3 long hours just to reach 74% level !!,however, after 2 and half hours of intensive usage it now stands at 70% !!.

full wipe kingdroid 5.1.1 and notecore v4 the best batt life on ics ever, and turn on the powersaving mode!
[Galaxy Note GT-N7000 General] rockky:
The battery usage on the Note MUST be addressed with V2 because it's been flat poor from the getgo.

It's especially evident now with my Nexus 7 use.....which has superb battery life...And it's only been one cycle.
[Galaxy Note GT-N7000 General] RavenY2K3:
That's not entirely fair though, I have two notes, one with the radio off and used in wifi mode only, that one can easily surpass days of use, because that extra radio is off. And considering the nexus 7 is wifi only, in that configuration the notes battery usage is great.

My personal opinion on this is, since ICS, something to do with how the modem/radio is used or how the data connection is handled, has been changed, and causing thwar battery issues. Although with my current config of 4.0.4 and the NoteCore kernel, I'm happy that for me "my personal" experience is that, it is on par or better than my phone was on Ginger Bread.

Strange.. I took mine off charge at 6.30am and im at 61% now at 2.36pm.. Ive watched the whole of qualifying on the bbc iplayer.. Been on and off facebook made one 6 minute call.. Plenty of texts.. Some web browsing and 6 youtube videos.. Total screen on time of 2hrs 18 minutes.. Did u flash at 100%
[Galaxy Note GT-N7000 General] TML1504:
LOT of BS in this thread! :p

as stated numerous times:

battery performance is always terrible for a few hours after a fresh install (flash), due to indexing, gallery app generating thumbnails etc.

let your phone settle for a few hours, and evaluate then!

another thing: i think braxos said that the cpu can only go down to 200mhz. this is definitely wrong, it can go down to at least 50, but this depends on the kernel used and it's tables!

Hi,

As with GB, for me WiFi is killing the beast. I shut it off (got unlimited data) and am back to normal.

Used it rather normally today (little bit of everything), almost 9 hours live and I'm at 42% capacity.

Noticed (I suppose) that Juice Defender and Deep Sleep Mode don't marry, This morning the GNote "woke up" but no way to get a connection (No 3G or WiFi possible). I rebooted and suspended Juice Defender, no troubles since.

---------- Post added at 01:37 AM ---------- Previous post was at 01:33 AM ----------

me here i got a bad battery life with ics 4.O.3 as it has the aos bug . i tried every ics build here and all they suck battery like a thirsty man drinking water :mad: . but i my brothers case who owns a galaxy nexus with 4.0.4 the battery life is far far better when he was on 4.0.3 he was suffering from battery draining and signal loss . so i believe it is the 4.0.3 problem as everybody know :eek:

Yeah for me the work around with unlocking the phone before unplugging doesnt work.

can u tell us where u get that from?
[Galaxy Note GT-N7000 General] richlum:
On LPY my phone wasn't going into deep sleep.

I followed these steps and it is going into deep sleep now when idle.

I'm not sure whether it was due to unplugging whilst the screen was locked, but I'll see how it goes after the next charge if I don't unlock the screen...
[Galaxy Note GT-N7000 General] bejoanakmami:
ive tried the unplug method for some times but it only worked once. then i found the method i referred and worked perfectly. however i just did a full charge while my note on, now it gets 200mhz again. idk whats going on. then i tried the method once again but without taking out the battery, only shut it down and wait for about 30s then power on, it goes deep sweep again. how strange... if someone have explanation abt this ill give a hug for free.
[Galaxy Note GT-N7000 General] tdodd:
There does seem to be something very wrong with the USB functioning and battery life. When I first upgraded to LPY, using Kies, the upgrade went smoothly enough. After the upgrade was complete I left the phone attached to bring it fully up to 100% and instead of charging it was discharging at an alarming rate even though the phone was left idle. Rebooting and putting it on the AC charger fixed it.

Yesterday I used an OTG adapter and briefly attached a USB flash stick. I ejected/unmounted the drive properly and removed it. Then, having just bought DSLR Controller (BETA) I attached my camera. That all seemed to work fine, but shortly afterwards I found the phone was very hot. It turned out that USBStorageUnmountter was holding a massive wakelock. I had to reboot.

I also rooted the phone using the new, easy method with the temporary CWM and that all went fine too. Since then, no dramas, until last night when I fired up Kies and attached the phone to the PC to see if Kies was happy with the phone. It was. I removed the phone and headed up to bed. A few minutes later I picked the phone up and found that it was hot to the touch (even through a gel case). I checked BBS and other monitor stats and found a huge MTP wakelock. I had to reboot to cure it.

So Kies and USB seems to screw the phone, as does OTG storage or camera or both. When these issues are not present the drain rate is very low, but just now I can't trust the phone not to hit me with a massive battery drain if I use USB, seemingly for anything other than AC charging.

I'm doing first run on cm9 #7 with anker battery, will post results
[Galaxy Note GT-N7000 General] Tonio78370:
Same problem here, I charged overnight, unlocked the phone before pulling the charger but it wouldn't go in to deep sleep and lost about 12% in 1 1/2 hour (constantly on 200 mHz). Only a reboot solved the problem.

I think I'll go back to stock GB and wait until I get the official update through KIES (if it makes a difference..?)
[Galaxy Note GT-N7000 General] musashiro:
i think the problem is that LPY doesnt go deepsleep..:(
[Galaxy Note GT-N7000 General] tdodd:
It definitely does go into deep sleep, unless something prevents it.

EDIT : Screen print added.
[Galaxy Note GT-N7000 General] dzontra11:
Deep sleep around 90% here.
[Galaxy Note GT-N7000 General] Braxos:
Today I was checking emails via social hub, twitter, Facebook, tapatalk and app updates. The phone did go from 100% to 88% in 40 min, brightness was at automatic, no gaming no music no video. I don't remember GB eating so fast battery. Maybe with full brightness. Waiting for the next firmware in max 2 weeks.
[Galaxy Note GT-N7000 General] musashiro:
tried clearing the ram but still, i dont go deepsleep..:(

will investigate more on this..
[Galaxy Note GT-N7000 General] tdodd:
To drop 12% in 40 minutes is equivalent to 18% per hour, which would mean over five hours of use with the screen constantly on and busy accessing data and updating the display throughout. I would think that is a fair rate of discharge while in active use, or am I missing something?

I don't know what keyboard you use, but I use SwiftkeyX and find it is quite a resource hog. It's good, but greedy for CPU cycles.

---------- Post added at 09:49 AM ---------- Previous post was at 09:36 AM ----------

Not an expert, so if I'm wrong here then apologies, but....

I don't see why clearing RAM would accomplish anything useful. AFAIK that won't kill active processes, like anything that is preventing deep sleep, but will simply unload inactive, pre-cached software which the OS will reload as it sees fit.

I think the right solution is to use BetterBatteryStats to identify extensive wakelocks, which are keeping the phone awake and to do a clean boot with the USB port disconnected in order to start with a clean slate. Leave the phone alone for 30 minutes following the reboot and then see what BBS has to offer.
[Galaxy Note GT-N7000 General] elijahtan:
my batt could barely last 10 hours... i seriously think LPY doesnt go into deep sleep well...will try to limit samsung apps by freezing on titanium
[Galaxy Note GT-N7000 General] tdodd:
Do you leave WiFi enabled? The default setting in the ROM is for WiFi to remain on during sleep and I think that prevents deep sleep from being achieved. I have mine set to turn WiFi off when the phone is sleeping, but I usually disable Wifi manually when I don't need it and only briefly enable it when I do need it.

Go to the WiFi advanced options to adjust the WiFi behaviour during "sleep".
[Galaxy Note GT-N7000 General] mug2k:
Try the instructions below, fixed my deep sleep problem(thanks to Mister Jozo)

0.go to settings > sound and turn off touch sounds and screen lock sounds

These steps stop the kernel wakelock 100% problem:

1.turn on aeroplane mode

2.turn off device

3.take out battery for 10 seconds

4.turn on device

5.wait for everything to load

6.turn off aeroplane mode

[Galaxy Note GT-N7000 General] ahalford:
So, I found the problem.

This is kernel wakelock, wlan_rx_wake.

Many people also suffered from this problem on Nexus.

The issue directly related to Dynamic IP/DHCP on your network. Due to kernel fault, wi-fi module can'to go into deep sleep, and therefore drains the battery. Not much, but about 2-3% per hour.

Goddamn Samsung devs.
[Galaxy Note GT-N7000 General] kurogane_s:

Which setting for db you're using?

Cause for me it stays same situation even after this WiFi Tx Power trick.
