Thanks mate.But it is not normal as it eats my battery I can't even charge it since it gets on 800 and sometimes 1400 cpu clock!So I ended up formatting my internal memory to solve the Media problem and now I'm getting Android Os usage shown in battery monitoring.And there was this one time I got the something help center wakelock.So idk what now but I installed bbs waiting to get deeper in the issue!(last time I used this app was when we had the gps wakelock problem back in GB.)

It sucks not having one single decent ROM for our note is it too much too ask?!

Are you wiping /system /data /preload /cache dalvik and .androidsecure before flashing your ROMs?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
How many wipes are you refering to exactly here?:D

Well just like always I do the 3 wipes (data,cache,dalvik cache) and then the ROM itself.Haven't had any problem so far except this time I ended up formatting the emmc too but I guess it was high time I did that since I've never wiped that part.Now I'm just waiting to see the results

Re: [HELP CENTER] How to prevent § handle wakelocks § save battery life[GUIDE] [β]

You got a lot of social apps installed. I would suggest to disable or lengthen the refresh durations of the apps especially facebook. If you didnt use data connections, switch to gsm only mode, your l2hsic wakelocks is higher than mine but in overall you used up about the same battery as mine. :)

Try those first and see the changes

Good stats though, do you have niantic ingress game installed? If so, you need to close this apps from the task manager as the app will keep on running the background, apart from that, is just the google sync feature. Either try to disable the sync or partial of it. And one last thing is titatnium backup, i would suggest go for manual backup than automatic.

Hope this helps :)

Sorry for being absent some time, been busy with some urgent personal matters.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
Yup after the stats I came to the same conclusion.So again before going to sleep I force stoped the social apps that I use and got about -0.6 % drainage over aprx 7 hours.Also I solved the "Media" wakelock which was way worse than this by formatting the internal memory.

But now let's get to online drainage!The l2hsic wakelock seems to be affected greatly over wifi use as I see the minutes rising in BBS is that normal?Also wlan_rx wakelock seems to be another problem?! .I'm wondering how much battery % should I be losing when wifi on with the phone screen off.(Btw I open the social apps that I mentioned earlier when I turn wifi on obviously(Line,wechat,whatsapp)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Re: [HELP CENTER] How to prevent § handle wakelocks § save battery life[GUIDE] [β]

L2hsic is a process found on most samsung phone mainly as well as chip i think. Its a very cheap method to implement in phones and what it does, is to store the cell id by keep refreshing itself. The poorer the signal, the more frequent this process will try to find a better reception. This is feom what i heard by one of the poster in the past, months ago and i think part of the information above is true only.

Try to turn off wifi and measure your batteries, with these scenarios

1. Wifi on with sync off and dual mode mobile network

2. Wifi off and dual mobile mode

3. Wifi on with gsm only

4. Wifi off with gsm

This is a lot of monitoring to do though but might be a good practice to try and save more juice.

But i got to say though, 1% per hour over 7-8 hours of data measurements is still considered as averagely optimal usage, more than 1.5 or 1.8 is quite abnormal

Ps

Wlan rx wakelock is the process of your wifi, if you could, reserve an ip address for the phone in your ap. Using a dhcp mode will keep the ip address refreshed overtime when the lease time expired and this will make the ap to assign new ip address for the phone.

Another thing is also can be from some of the process like social apps updating itself. I am not roo sure about this, just some theories regarding processes. Hope these info helps :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
:good:

Thanks for your info it does help I've read about l2hsic and mine seems to be directly related to wifi.As I said with wifi off I got very good results and l2hsic count was less than 1 minute over 7-8 hours(social apps force closed of course).Today I charged the battery to 100% then with wifi on + wechat and whatsapp I lost 10% over about two hours,l2hsic about 27 minutes and wlan rx wakelock around 24 minutes.Under "alarms" in BBS Wechat had the biggest wake up count(about 50) follwed by whatsapp (20),rest are negligable.

I'm curious to know how much is considered normal(in term of %) when wifi is on with say one or two background apps such as the mentioned ones and maybe improve it if possible.So any ideas based on the numbers I wrote?Too much?normal?could be better?How many % other lose with their wifi on in JB?etc...

And one more thing what's this sec-battery-monitor?Couldn't find anything about it here or anything useful elsewhere.it had a 13 minute wakelock.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
As mentioned before in my previous posts, getting 0.1% per hour over 8 hour monitoring is quite hard. That is because due to several reasons.

1. Battery conditions

2. Background process running

3. Network coverage e.g. 2g/3g/4g and others

My battery has bloated probably due to overcharge and often doing battery calibration with the app found in google play as well as getting my phone pretty hot (didn't see much impact on battery here). When the battery has bloated, the battery charge capacities is abnormal and the currents inside is also quite unstable (let's leave this bloated battery discussion later on or on another thread :)).

I too had Wechat installed before and it does consumes a lot of battery compared to other services. Major weakness of wechat is because it lacked the option to change the refresh interval like facebook app. wechat is a full packaged messaging systems or you could say that wechat is an alternative version of facebook only that it lives on smartphones though (I think). In the end, I removed wechat from my phone due to heavy network updates even though you're inactive in wechat.

If l2hsic really does related to wifi, it's probably because most smartphones had Markov Decision Process (MDP) implemented. Although I'm not sure how this works actually (sorry ahalford, going off topic slightly) but mdp is good to have since if you're having two kind of internet access, wifi and 3g/4g, this process will kicks in and depending on how it is preconfigured, it may switch to either wifi or 3g/4g whichever has a good QoS (Quality of Service).

In my opinion about optimal battery usage when the phone is in a deep sleep state over 7-8 hours of measurements,

(x.x%/hour)

usage<0.8% = very good management

0.8%<usage<1.4% = average with several online based apps installed (but could do better)

1.5%<usage = a very high wakelock issues, need to check and uninstall several apps

I'm not a pro in these but I'm trying to help :). I've used several earlier smartphones especially n95 last time, battery usage was heavy (1 day from 100 to 0%). Battery life is very important and managing it on smartphones were never easy.

So, having 1.0%/hour is not that bad, considering that you never used your phone or accidentally hidden it somewhere in your house, could last you for 100 hours, roughly four days. Hope the above information helps :)

Sorry to ahalford for having several off-topic posts, but could prove useful :D
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
Very helpul info indeed;)

I don't think this is off-topic it can definitely help others better manage their battery drain.I did a little search on Wechat and it turns out it is a battery drainer.I can say my problem is solved since a week ago.So to sum it up here's what I did:

1)I had the "Media" wake-lock which was way worse than others.

Solution:Formatted my internal memory.(It's also mentioned on the first page of this thread)

2)The Wechat wakelock which affected the battery when wifi was off and even worse when it was on.

Solution:I chose to force stop it when not using.It's a wonderful app with unique features in its kind otherwise I would've unistalled it.

I also had drain problem with Freepp app but this was in ICS.Unistalled it and problem solved.

There's this thread I came across to when searching about this whole thing it's a list of apps that cause battery drain introduced by users guess it can be useful.

By the way great thread ahalford very helpful well done:good:

Re: [HELP CENTER] How to prevent § handle wakelocks § save battery life[GUIDE] [β]

Yeap, good findings as well, but i gotta say, kinda lacked of a more accurate data to assume the apps is a battery drain. Say, in the thread you linked from here, the battery drainer apps lists, in the page 4 there is an app to manage the data connection in the background, could you test that for me and send the dump here? The app seems famous though with about 6 million downloads but i am slightly doubt the fact of the app having those features like juice defender.

Sorry for asking, it is because my battery has bloated and i cant continue monitor any more data since my screen will flicker and turned off when the indicator is about 50% or heavy usage, not sure which one

Thanks in advance :)

Ps

Maybe i also should create the same topic for n7000 specific posted by user with a more accurate data? :confused:

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Looks good, it's like a task manager that would kill running background processes immediately (I guess). I would like to try it but couldn't though because of my battery condition now not allowing me to have a very accurate data, a very accurate data would be having 2 kind of scenarios, with and without the app and each scenario must have at least 3 data collected from bbs with at least 7 hours each... I hope you could do it and post them here for me to make comparisons? :highfive:

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Get yourself a bbs first, before going to sleep, go into bbs>menu>set custom ref and you're good to go, leave the phone when you are asleep, the best practice to get good measurements though...

Each time after you wake up, first thing you had to do is to open your phone, go to bbs>dump to file (top right corner). The dumped file should be saved in your internal sdcard :D

Try not to install or change any apps or settings during this data collections

1. Without greenify,

2. With greenify and several apps put into the lists. (probably after you send the dump file here for the first scenario, then we will pick which app should be hibernated)

Probably I'm asking too much :P

But thanks in advance, looking forward to those data :)

P.S:

Try to avoid heavy usage such as playing games before doing the data collections :)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
You are talking about wifi manager I suppose so I installed the latest version and made the dump file which is attached below as you asked.

It could be a good idea if people participate and procure accurate data regarding the apps to make a final decision.

(wifi manager is working in the background and I didn't change any settings after opening it)
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Sorry, it's not the wifi manager, it's the 2x battery - battery saver and after looking at your dump file, it states that it is -0.1%/hour, which means you used your note heavily before the data measurement/custom references takes place in bbs. This occurred because the phone estimates how many battery remains under current usage. Let's say playing a heavy 3d graphics game from 100% fully charge notifiations appeared and play the game till 0%, would took you 2-4 hours (estimated) while browsing only 4-6 hours (estimated). When you stopped playing the heavy 3d game around 50% battery left, after quite a while the % indicator would go up by about 1-2% overtime... sounds very weird but this is what I would think since sometimes I would get some battery % increment when I looked at stock battery monitoring in setting. But I'm not sure if this is true though probably others also do notice this

Here is something from the past when my battery was still in good condition:)

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] galaxynotes:
I know exactly what you mean happens to me too but it doesn't matter because if it were to drop more than 2-3% it would minus that 1%.I got about the same result the night before about 0.1-0.2 %/h.So I think I can say it's on its optimum level.Kind of like yours there back in January.I wonder what happened to your battery after that it's only been two months since then!

I will test said application and share the results.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
Haha... sad case, probably overcharged and used my phone quite heavy to play certain games till it became hot... but I don't see connections when the phone gets hot and the batteries and I bought my note somewhere in 22nd-23rd January 2012, last year though. A thread in this section, screen flickering or something for its title, they say that's a standard for the battery usage of 1 year or slightly over, but didn't know if its all note users also impacted in battery lifespan of 1 year as well

Sunny, looking at those:

NetworkLocationLocator (Google Services): 3 m 6 s (186 s) Count:277 0.6%
GpsLocationProvider (Android System): 2 m 32 s (152 s) Count:155 0.5%
RILJ (Phone): 1 m 49 s (109 s) Count:679 0.4%

I intend to think, that the reason is the same, as stated in a previous case - Network Location services and the apps, which using it. Try to disable it, and see what you get.

Ok, it is defenately location service that does not allow to deep sleep. Just turned Location back on and after an hour of normal behaviour (deep sleep and all others regimes) my device started to be awake all time. Now turned location off and all goes to normal again.

Is it a bug of custom ROM (cm10 and cm10 based)? While I had last official ICS (4.0.4) ROM everything was fine with the same pack of apps and settings?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ahalford:
Probably...not a bug, but a sort of incompatibility with existing CM code, I'd say...only when CM team will have a proper Samsung's 4.1 code, then we'll be able to judge.

Also - it can be app based problem, not service based. Because I never had RILJ wakelocks on any CM10 rom.

Last thing I can think of - is a modem. Rare, but can be. Especially, hearing about huge differences on same modems and different operators in Russia. LB2, LR1 and LPT are most popular ones there, so, you can make a experiment, if you want.

A word of advice about BBS app: sometimes it shows "no reference set" (no data) for hours after first install.

If that happens the case, you need to charge your battery and it will start working after you unplug your phone. Just make sure

to grant BBS root privileges when Superuser asks you to.

It's more "try & see" answer. Despite, it's not so different from general Android power saving policy.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sarf2k4:
To conclude, the worst would be having 2x battery saver, it makes the phone having more wakelocks especially the connectivity service, 5.5% in total and drained a lot; -30% (72% to 42%) [3.4%/h],

The first and second dump however, as far as I can remember, there isn't much differences actually, hill climb racing didn't cause much wakelocks and greenify's capabilities still low because I don't have much apps installed that can cause wakelocks, having IM to be greenified is out of the question but I will add 1 or 2 more dumps with naver.line greenified, other process as well to get clear results of greenify.

Hi, this would probably be my first post. I've read through most of the posts in this thread, but maybe you guys can help..

Serious wakelocks on my N7000.. phone was just recently installed with stock 4.1.2 Jellybean DXLSE firmware via odin.. also using stock kernel. The only mod I have on this would be root and busybox. I do have facebook installed though and some other games, but i dont think those are causing the serious battery drain. I already logged out of Google+, Google Talk, and disabled all location services and syncs. Wake up commands for Voice talk have already been disabled. Wifi is set to "Always". I've already tried flight mode, and still the l2_hsic wakelock still prevents my phone from deep sleeping. I've also tried the power off - remove battery - reinsert battery trick but still doesn't seem to fix it. I can't think of anything else to reduce the drain. Attached here would be my BBS dump file..
