Hi,

How is performance on next days and so...

As i am also planning for same thing you did....

And system restore wil gb back or ics only?
[Galaxy Note GT-N7000 General] lindvalll:
I recommend CPUspy (Google Play) to keep track of the CPU clock speed.
[Galaxy Note GT-N7000 General] mingonn:
Something weird happened this morning, was using google reader over GPRS (bad 3g signal in bed) after having turned on then un plugging. Ten minutes later noticed the back of the phone near the camera was getting really hot, checked battery and it had dropped to 86% ! That was about 20 minutes off the charger from 100%

Hope Sammy have an update coming soon, this release seems like a real rush job. Maybe if they spent less time fiddling with touch wiz and more time getting the basics right...
[Galaxy Note GT-N7000 General] David G:
Hi, I had the same problem as you...i.e. my Note was lasting for 24hrs+ on GB but was barely lasting 7hrs on ICS. I installed CPU SPY from google play store as well as BATTERY SPY from the same location; noticed that my Note was not going into "deep sleep" with the screen off and was horrified at the battery drain of between 22% to 40% under moderate usage. To cut a long story short, I uninstalled POWER AMP, LOOK-OUT and Google PLAY BOOKS and rebooted the phone.

I am now getting 36hrs+ on ICS and the phone is going into deep sleep..woo hoo!!.

Still testing to identify exactly which of these three apps was causing the phone to fail to go into deep sleep.
[Galaxy Note GT-N7000 General] nnick:
I don't have any of the apps mentioned above, I've done a hard reset too. Nothing. Battery life - crappier than ever.
[Galaxy Note GT-N7000 General] Moandal:
When you remove the phone from the charger, do you unlock the phone before unplugging? If not, that could be your problem - it was for me.
[Galaxy Note GT-N7000 General] Madman1209:
Hi,

yeah, check it with "CPU Spy".

Or flash a different Kernel (if that is an option for you) - they vary greatly concerning battery consumption.

Greetz,

CWM recovery wipe

I upgraded from stock GB to stock ICS and faced the same problem everyone faced here, from bad battery life to phone not going to deep sleep.

The various tricks explained in this thread helped somewhat but only temporary.

So I finally tried CWM wipe and now all the bugs are gone. In fact, battery life in ICS is significantly better than in GB.

Here's how to do it:

1. Backup

2. On main screen, press vol up button, home button and power button together, until the green android robot shows up.

3. Wipe data and cache

4. Reboot and done.

Hope this helps!
[Galaxy Note GT-N7000 General] chintanm87:
i did the same thing but deepsleep issue still persist

Hi,

i followed as you suggested but no luck with me... still same problems..

Do you have any specific settings / installation?
[Galaxy Note GT-N7000 General] friedje:
Start by doing the most simple and effective solution:

Turn off the phone, take out the battery for at least 1 minute

then put it back in and start your phone.

This resolves the Fuel-Alert kernel wakelock which causes a lot of pain...
[Galaxy Note GT-N7000 General] Ast2001:
Most of the time, you don't need to remove the battery but in all cases, the l2_hsic wakelock problem come back after a few hours / days.
[Galaxy Note GT-N7000 General] friedje:
Just rebooting does nothing on my note.

Taking out the battery solves the battery drain.

Yes it does come back, but then again you can always do it again..
[Galaxy Note GT-N7000 General] Ast2001:
You have to switch into airplane mode before rebooting.

prolong battery life

I do this every once a week..completely off your phone and charge it full.
[Galaxy Note GT-N7000 General] psnorth538:
maybe your battery has gone
[Galaxy Note GT-N7000 General] DaBountyHunter:
does anyone know how to stop 'partial wake locks' I've noticed I got quite a few one being the Audio_1 or something (forgive me I'm new to android). I've turned off all the lock screen sounds and vibrations but I'm certain there's a still a few culprits that are eating my battery when the phone is asleep.

So far I've managed to get my phone to stay in a deep sleep when not in use but like others I find after a few days this problem comes back.

Currently have gone 8 hours and still at 97%. Phone signal plays a big part in keeping battery life. If you're in a bad signal area it seems to drain the battery quite quickly.

ICS battery pain

Upgraded to ICS on June 6th.

Have experienced terrible battery life ever since. I've run down the battery to 0% 4 or 5 times, unlocked before disconnecting. Its increased from the 5 hours I got on the first day, but it is still woefully poor. Previously on GB I was getting 18 to 20. I'm running stock everything.

Full power down yesterday night, unlocked before unplugging today, at work today I kept tabs on the consumption and it's still rubbish (see pic)

via.me/-1y2izx0 (sorry still an n00b)

It crashed for no reason in the afternoon, pulled a soft reset on itself without me doing anything and I lost another almost 10%. I panicked a bit after that and plugged my phone in. As you can see, it still kept draining.

Have to say, I'm heartbroken - ICS has ruined the Note for me.

I'm definitely getting very little deep sleep and it makes sense that the wifi is keeping it awake, but what can I do?
[Galaxy Note GT-N7000 General] DaBountyHunter:
After I did a full charge 100% with phone off (put in airplane mode before powered off) then turned off the mode. I've been going 1% loss every hour. Currently at 71% battery after 29 hours! :)

This is on stock ICS 4.0.3 ROM.
[Galaxy Note GT-N7000 General] raines43:
Have you tried changing the' Keep Wi-Fi on during sleep' option to 'Never'? Since I did this battery life has been loads better.

It's under 'System Settings/Wi-Fi' - Press Menu button, choose 'Advanced', and it's the 2nd option down.
[Galaxy Note GT-N7000 General] ridgmont61:
Have achieved excellent battery life at last:

I initially tried the LPY German Version of ICS, but reverted back to GB as battery life was poor and many crashes.

I have followed the advice above and read comments by ifb-online. I have now gone back to ICS but prior to this did a reset in GB, then after installing ICS did another reset and a USB format.

It was a bit of a faff as all Apps needed to be reinstalled and then configured.

The phone is now far more stable (than previous ICS and as stable as GB) and now that I have also under settings>applications>all I have disabled apps that I was not going to use I have found that battery life is excellent.

As an example yesterday phone was taken off charge at 8am, used lightly all day on wi-fi and at 9pm battery was showing at 70%. Today from 8am to 1pm battery has dropped by just 8% to 92%.

So it is possible to get stable ICS and with excellent battery use.
[Galaxy Note GT-N7000 General] tdodd:
I've been through that same experience, thinking that everything was rosy, but it didn't take long for the illusion to be shattered once again and I'm now back on GB for the second time (third if you include the fact that I started out on GB in the first place).

If you can get the phone to continue playing nicely when you start re-charging it or connecting to a laptop then you'll be a luckier individual than me. In my experience any USB connection sends the thing (unpredictably) crazy and I have no intention of having to reboot every time I remove a USB device. There is crap going on with ICS that just did not happen with GB, no matter how many wipes and re-installs you slog through.
[Galaxy Note GT-N7000 General] faisal:
I have ZSLPF. For the first few weeks, I had good battery life (unplugged at 8 am, with about 65% at 6 pm). Then suddenly it plummeted (20% at 6 pm) and I wasn't sure what had happened. I used CPU Spy and there was no deep sleep.

I did the following

1. Removed Mobile Odin (not sure if this had anything to do with it but it was the only new install during that time)

2. Disabled the "touch sounds" and "screen lock sound"

3. Did the 'airplane mode, battery out routine'

4. Changed refresh settings in Pulse, Facebook app, News and Weather Widget to every 6h

5. Wake up the phone before unplugging

Not sure what worked out of some of these "magical" type steps...but I am back to better battery life (8 am to 6 pm, 65% remaining).

Usage hasn't changed during this time.
[Galaxy Note GT-N7000 General] Ast2001:
I have noticed two differents wakelock preventing the Note to go into deep sleep.

. The first one is l2_hsic

To return in a normal state, I have to switch into airplane mode, reboot and switch into normal mode

. The second one is fuel_alerted (less frequent in my case).

To return in a normal state, I have to switch into airplane mode, power off, remove battery for 10 sec, power on and switch again into normal mode

I use BetterBatteryStats to look on a regular basis at the Kernel Wakelocks. It's a very very uncomfortable position and I hope that Samsung Engineers are aware of the problem.
[Galaxy Note GT-N7000 General] Unmarked Door:
Thanks man - I thought to try that one myself and I can report a slight increase in battery life, (but not that much). Still no deep sleep though.

Sent from my still glitchy GT-N7000 running stock ICS
[Galaxy Note GT-N7000 General] Davrat:
For me it was simply step 5. I've checked the various combinations it at least half a dozen times and it was certainly step 5 that solved my problem.

You can clear the bug at any time even if you have triggered it by taking your Note off charge and didn't unlock it and you can't put it back on charge. All you do is unlock and then press the power button, give it a minute or two and then check with CPU spy and you'll see its gone back to deep sleeping.
[Galaxy Note GT-N7000 General] Beards:
Mine was sorted simply by doing what I normally do once every couple of months:-

Let it drain right down to zero, recharge & keep it off but leave plugged in for a further 2 hours min (roughly 5hrs min). Unplug, switch on and it's re calibrated.

Note: Don't do it too often as you can damage the cells in the battery when letting it drain completely.
[Galaxy Note GT-N7000 General] nnick:
That doesn't work for me though :-(
[Galaxy Note GT-N7000 General] DaBountyHunter:
Not bad I've passed the full two day mark with my note on ics 4.0.3 stock ROM...
[Galaxy Note GT-N7000 General] Beards:
Not ideal but have you tried after charging turn off all power on the phone then restart.

Again it is not ideal but at least it should keep the calibration running correctly.

Hi..

How you got battery life back?
[Galaxy Note GT-N7000 General] ukjeeper:
Tried the fixes in the thread, but still not getting even 24 hours out of the Note on ICS:

Pretty much convinced i should go back to GB.
[Galaxy Note GT-N7000 General] Beards:
Something does not look right with your battery graph under GB. You have four separate occasions showing where the graph percentage has risen despite not being charged.
[Galaxy Note GT-N7000 General] ukjeeper:
Yeah, that was just pointed out by someone else on twitter. They questioned if i had plugged it in at some point. Perhaps my recollection of that weekend is not as good as i thought (was a while ago).

So should i be happy that i justabout make 21-22 hours on a charge, on either ORS?
[Galaxy Note GT-N7000 General] Beards:
Provided you got the hours under one single charge and you use moderate to good use of the Note then 21-22 hours to me is fine. :)

Excellent battery life for me on ICS

Hi,

I am having Stock ICS India.

Mine is getting better and better day by day.

Moderate use : I get almost 36+ Hours (till battery = 10%)

Good Usage : I get almost 26+ Hours (till battery = 10%)

I always have with data on + wifi On(no matter if I am in wifi network on not ) , + no battery save software + push mode of Email + Auto sync on all time + Auto Brightness :D

Here is the screenshot I took just now. I am in office since morning so I would say this screenshot as moderate usage.

I am rooted but nothing (app) installed or removed , my phone is having all factory default apps as well.

Battery Life Problem

How long does the galaxy note battery supposed to last on a normal use?

By normal use, I mean, its mostly in my pocket, and I get it out from time to time to check on social network stuffs, messages, or whatever, but not playing a game in it.

I've had my Note for about a month now, and yes, when I upgraded to ICS, I've had the battery problems as well, but managed to get it better doing the fixes that I got from this forum( ex. airplane mode fix ). However, what bothers me is that many are claiming to have reached more than 24 hours with it, even 36, when I don't even seem to reach that.

When I get home at night, I usually HAVE TO charge around 10pm, and I normally bring it out on my usual day at around 8am, so its about only 12-16 hours for me. I normally have 3G on, and wifi too.

So, with all these , I'm wondering if this is a normal battery span for a samsung device. This is the first time I had an android device, a samsung, and am wondering if I made the right choice.
[Galaxy Note GT-N7000 General] Baker0:
Download cpu spy and see if your phone goes in to sleepmode.

I do the same as you. ...
[Galaxy Note GT-N7000 General] Beards:
Besides using CPU Spy another test you can use which will give you an immediate answer is to do the following:-

Before bed put the Note into Airplane mode, make a note of the Battery percentage and turn off the screen.

In the morning turn on the screen and before you do anything else check the battery performance.

It should not have dropped more than a couple of percentage, four at a very most but even that is excessive.
[Galaxy Note GT-N7000 General] erwinkamal:
Im always on stock rom since dec last year. Unrooted.

Keep updating my stock firmware either thru ota or kies whenever it is released by samsung.

Now mine is on stock ics and Im quite satisfied with its performance and battery life.

I feel it is beter than stock gb.

After upgrading to ics, I let it finished auto downloading all apps and re-register google market.

Then on this first ics, I wiped it completely. All previously have apps, could be obtained back from google market as well.

Battery life initially was terrible.

After couple of days and several times restarting, it was getting better.

I disable some of those unused stock apps, and put disable all auto update of apps.

I set all my push mail accounts to sync:

-every 15 min for weeks days peak hr.

-every 4 hrs for non weekdays non peak hr.

It is now stable and snappy.

However I observe that for unknown reason, couple of times after I did updating apps from google market, my battery is getting hot and its percentage down very fast.

And it could only be solved by restarting it.

So from now on, I always restarting it after updating any apps from google market.

[Galaxy Note GT-N7000 General] sitanshu91:
Guys what I have noticed is battery life depends on your use

Some people claim to get 36 hours of battery life but then guys you should check what is the screen on time

I think if you are continually on note doing something with the screen on time of 4hrs approx with wifi is good enough

I feel for battery life you should monitor

1) whether phone goes in deep sleep (use cpu spy)

2) scree on time

3) time spent on voice calls
[Galaxy Note GT-N7000 General] Rampy87:
I usually get around 30hrs+ time ( i usually charge to full then let it drain to 25%)

in that my use is as follows:

talk time: approx 2-3 hrs

Internet: less than 1 hr

Facebook, gmail , twitter linkedin etc are kept running background sync is on

some heavy games about 10-15 mins

The best thing about note i found is when you are not using it the standby time is insanely high. If your note doesn't goto sleep properly then only will you have low life
[Galaxy Note GT-N7000 General] gqonmars:
from 20hrs - 48hrs

I just updated my note to ICS 4.0.3 for about 1 week

PDA: N7000UBLPC

PHONE: N7000WELP7

CSC:N7000UUBLP9

I bought this from Amazon and its a white note I think from Trinidad.

After ics update, I was getting pretty bad life (not rooted) which last around 20 hours with 3 hours of screen time that I used pretty heavyly as I was re-installing lots of apps.

Once I was done with that monster task of installing like 50+ apps, including Juice Defender which I set night mode to 2-6am and Frequency of 30mins

I also disabled almost all the apps which I see running that i did not want. (some the disable button was not allowed??? strange)

I am now getting about 48 hours until 5% or so.

Screen time is still around 3 hours (surf web, play some games, LOTS of texting and emailing) (no more installing apps)

About 30 mins on the phone

Right now my phone shows

88% in Deep Sleep (via CPS Spy) 34:16:49

5% in 200MHZ 2:20:18

...

..

this is with 34% battery life left on this battery (on the standard 2500mah battery)

The most I like about this update is the email, which seems to be much better than the 2.3.6 OS. :)
[Galaxy Note GT-N7000 General] DaBountyHunter:
I've found a guaranteed way to get 'deep cycle' sleep for my note (works for me). I have all syncing apps disabled.

I charge my phone up until I see the 100% little icon in the top left.

Turn airplane mode on.

Turn the phone off. With cable still in.

Wait for the large battery icon to appear and you'll see it isn't 100% full it's more 95% full. Let this charge fully till it's "100%"

Once that's done... unplug charger turn on phone and turn airplane mode off.

You're phone will go in deep sleep and you should get much better battery life.

Thanks

[Galaxy Note GT-N7000 General] garytube:
since 2 days i get horribal battery drain. 30% in 15min without using the note.

i notice this after the latest busybox update but thats just a guess.

Bluetooth is eating up all my battery and prevent my device going into deep sleep.

but i never turn on bluetooth and it never was.

but badass battery monitor shows that the processes sh and immvibed is draining my battery. yesterday it took 84%

i'm really lost on that problem

about the screenshot:

everytime i refresh my battery-view (pic.02) the bluetooth-time goes up..

Update:

the process "sh" is causing my problem - can somebody pls explain me whats wrong with it?!
[Galaxy Note GT-N7000 General] tdodd:
While that might all work, surely in this day and age we should not have to do all that simply to get our devices to work as intended. None of that is necessary with the GB ROMs and that is why, for now, I am back on GB once more. It is like a breath of fresh air not to have to worry about whether or not the phone is performing as it should. It all just works.

Right now it is 3 days and 2 hours since my phone came off charge. I've had almost 2 hours of on screen time, mostly with WiFi on, a little bit of GPS too, and the battery now stands at 47%. I have not turned it off, nor rebooted, nor switched to airplane mode in all that time.

If ICS could achieve similar performance I'd be very happy, but my experiences so far, having tried LPY a couple of times, for a couple of weeks in total at least, is that it doesn't come close. Until Samsung releases something which works reliably I am more content to stay with GB and stop fussing with the phone altogether.

A question after a bit of context.

My phone does go into deep sleep.

I turn off wifi at night. I have juice defender installed which kills data connection a few seconds after display turns off.

With deep sleep I'm getting close to 12 hours (8am to about 9pm) on a single charge.

I might be a heavy user;

2 exchange accounts,

Facebook, twitter, G+, Tapatalk. I'll check these apps maybe 10 times a day, and except twitter which I check constantly (15-20 times a day).

SwiftKey X 3 (beta)

It's only when I actually use my phone that the battery life drains quickly. Deep sleep gives me about 1% per hour or even better.

The device e in use drains the battery right before my eyes. I started typing g this message at 97-98% and after 5 mins of reading the last 3 pages and typing this post, I'm down to 93%. That's 5% in about 5, maybe 6 minutes.

Is everyone experiencing the same level of drain during active use?

Not a lot of purpose to have a phone last you only if you don't use it...

Is anyone aware if apps like Tasker use more battery when changing from one Active Profile to the next?
