Battery drainage on Galaxy Note

Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.

That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.

I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.

Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.

Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though

No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air

I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity

Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.

[Q] Mobile Network Signal (Cell Standby) DRAIN

Hello guys I'm a newbie here so please do explain to me some of the stuff if you need to
so recently (about 2 weeks ago) I used this guide to root my Incredible S and did everything except the Blackrose part
and since then
I've noticed that my phone has drained its battery a lot quicker than usual
I lost 11% of battery when I woke up, fully charging it the night before
I usually do not use it much, only a call every 2 days or so, and I do not have internet connection
so I cannot understand how I have to charge it every day now, when it used to last 4 days (on Sense)
here's a pic from betterybatterystats
thanks everyone
------- 4/10 edit
ok
back to stock rom
it has the SAME problem
"No data connection" and "No or Unknown Signal" on Betterbatterystats
with steep drops in battery whenever there is "Mobile network signal"
and next to no drop whatsoever when there isn't
PLEASE HELP ><
new attachments down there with stock rom
tell me if you need a translation
THANKS

Battery drain has already been discussed much in the CM10.1 thread. Its been discussed in practically every AOSP thread really.

I know and I've tried to look around for answers for quite a few days
but for most people
it's either the same as Sense or something else (too many apps, not charging fully...)
and for those with similar conditions
I can't find solutions for
and the problem got worse today
in the 7 hours I slept yesterday
the battery drained from more than 50% to nothing
so the alarm didn't ring because it shut itself off

The standard charging time isnt what it says on the box or anything. It should be roughly 6 hours from 0% to 100% and thats providing you plug it into an AC outlet. I would suggest trying an app called Greenify. It hibernates certain apps/ services that may not be in use thus saving battery. I would also regularly check the Running Apps in settings and clear out anything unecessary.

nonono
I don't have a charging problem
it's a drainage problem
and about Greenify
I already installed that when I looked over the battery saving guide (which didn't help)
I literally have 5 apps in the Running Apps section
the part I don't get is
why does Cyanogenmod 10.1 use battery so much quicker than Sense
when I have 1/4 the apps I originally did?
it's the "No Data Connection" and "No or Unknown Signal" part really bothers me.
oh and thanks for the time btw

Hmm then this battery drainage is strange. Try making a full backup in recovery. Then clean flash the ROM again. If the problem still persists, then I have absolutely no idea whats wrong lol

Actually
I tried that...
on Sunday afternoon I reflashed it
my exact steps:
1. ClockworkMod backup
2. Install from zip
3. Advanced restore - data (I restored the whole thing too once before that, but thought that just restoring the data might actually change something)
and that's when it went from 50% to 0 overnight
not looking too good -.-

Well then sit tight. Szezso is gonna release a CM10.1 for us as soon as he gets his new USB port.

oh well then
thanks for the help anyways
I'll just keep waiting
might want to go back to Sense though...
and more pics from BetterBatteryStats
just in case anyone knows what they mean

Drained 56% of my battery while I was asleep yesterday (for about 7 hours)
only 6% in the time I was at school, because of Airplane mode (I even listened to music and played a little Doodle Jump)
but I obviously want a phone to CALL PEOPLE
so I'm reverting to stock Rom

OK
so that didn't work out
I edited the main article
hope someone can help!!
meanwhile I'll look for more articles online since I know it's not (really) CM's problem anymore
thanks

Ensure to charge your mobile fully and after a NORMAL usage (calls, WiFi, Mobile Data on).
Just share the dump file from betterbatterystats. It would help to analyse better.
Edit:
Could notice you are using some widgets in the home screen. Usually widgets with high refresh rate drains your battery.
2. Facebook app is causing the partial wakelock. Even when the screen is off, the app is using your CPU. Try to disable autosync if it's enabled
3. Audio_out3 wakelock is due to phone vibrator is enabled. May be during call or keyboard haptic feature.
Power manager service wakelock is common and its in good level.
Try to check your CPU freq n governor.
And adjust accordingly. One more, Li-on battery should not be charged fully. Just charge till 85-90%. The battery will drain little lower compared to fully charged device. And you need to charge your device only when battery is low. Frequent charging n discharging will affect the battery life. Consistent Charge and discharge cycle is encouraged.
Try to share your fresh dump here or in batter battery status thread. There are many folks to help you with.

Thanks for the detailed reply sir
My widgets (aka weather & tasks) only refresh manually, and nothing is on Autosync (in the auto sync menu, anyways)
originally had only vibration for calls, turned that off too now
and what is "CPU freq n governor"?
didn't know that about the batteries
I'll do that next time
and I just reinstalled betterbatterystats, so I'll post the Dump File after a few hours
Thanks again!!

I mean CPU frequency steps and CPU governor. It's a kernel thing. Just search xda, you will lot of info regarding that.
Sure, post your dump with normal usage.

Battery Stats - non rooted

Is the battery life really that good? I really can't get more than 2 hours of SCREEN time with broken use or 3 hours of concentrated use. The International had a thread about this, but those are GSM and running custom ROMs and kernels.
Post your crazy good (or bad) battery Stats here with setups and sync settings. Stock non Rooted preferred, but maybe someone here can convince me to root my phone again!

I'm having the same problem

I'm currently rooted running d3rp but when I've had it stock I get pretty great battery life. Definitely no complaints. Maybe a hardware issue with some phones?

I get about four hours on screen time. And twelve standby. It's enough to get me through the day, and I'm alright with that.

I'm on derpone. I uninstall everything I don't use (Facebook, Twitter, chrome, ect), turn off auto sync, I'm also on the experimental x kernel, unlocked to 1.5ghz, under volted, and have thermal throttling set to the highest (coolest?) Setting. Oh and I have the battery saver on, everything is enabled aside from the brightness control.
...wow I do a lot of stuff.

HTC took it out of the stock settings, the only way to see is with a battery monitor like better battery stats.
Sent from my HTCONE using xda app-developers app

Is Gsam a good monitor? I have power saver off (I see no real difference in battery life) but the screen uses like a maximum of 10% of my power. The kernel uses like 25%. Apps account for 75% of battery usage.

You've probably already searched some if you're asking, but I wanted to make sure you have seen this thread:
http://forum.xda-developers.com/showthread.php?t=2249497
It includes my tip that turned me from disappointed w/ battery life to impressed. (By setting every social app, blink feed, weather, (but not calendar, gmail, or other google services)) to manual sync... and my phone lives most of its life in below average signal strength areas.
Otherwise, I'm running non-rooted, stock, and no battery tweaking apps, or memory freeing apps, etc.

How do I make sure only my google stuff auto syncs? I could care less about the main facebook app. (I need the messenger though, lol).
If I uncheck everything in the Facebook section of Accts and Sync, will it sync at all? Like, when I run the app?
But if GSam is right, then my main problem is the Android Os and kernel. Together, they eat up about 30% of my battery, sometimes more.

Yeah, that's it, you got it. Settings > Accounts and Sync.
My theory was the phone would never be able to turn itself down to a lower power state since one thing or another would always be keeping the data connection active. Used to barely clear 1 day, and now 2 is no problem.
Apps with sync off just update when you open them. Made sense to me!
Good luck.

I have wifi always on with "data connection" unticked and "Sleep mode" ticked because I seen this from htc's website "Keep in mind though that the Sleep mode option for the data connection in Settings > Power, when enabled, overrides power saver mode." Here are some screen shots my brightness is manually set at 20%.

An exercise in battery longevity.

Hello everyone, im here to share my future experiences with seeing just how far i can push my battery and share how i did it with everyone.
Backstory:
I'm going hiking in Virginia tomorrow for a week, and would really like to have a camera without carrying extra devices, so..... its time to mod my nexus 5 as low power as possible!
here are some of the "prep steps" that ive done in order to obtain my battery life, i'll update the thread to let everyone know how it worked out!
Rooted
CM stable installed. (up to date as of this post)
Screen Brightness set to low as possibe.
Elemental X Kernel installed (Using TricksterMOD, these are my settings)
Multicore power saving = 2
CPU Freq. Lock= Min( 652800) Max( 652800) Max.screen off(300mhz)
Google Now/voice anything turned off
Home screen has only one page
Airplane Mode
Greenify Installed, Using Xposed Module for advanced/better control
Hibernating almost everything 3rd party, esp things like Facebook,KiK etc.)
BootManager xposed module installed, everything disabled that isn't needed.
Installed gsam for more meaningful data logging.
Unchecked Auto Sync Data in the Data Usage settings
Changed CPU clock min/max 652800
Installed Deep sleep battery saver Xposed module. (on slumber profile) buts phone into deep sleep when screen is off.
If i remember anything else i did on here, i'll post it.
(sorry its taking so long for replies/updates, "new user status" prevents my posts 5 minutes in between.) (hard to believe, been a member since 2011, just lurked alot.)
*May have found lower limit on the CPU, no instability as of yet, however phone is acting a bit erratic, looking into this currently. (booting takes FOREVER. this is a problem.)
*Trickster seems to pick and choose sometimes whether it wants to listen to me, sometimes CPU freq. on sreen off is changing to 652800 on its own. :/ anyone know of a way to get it to respect my settings?
*Changed CPU freq. to min max 652800 based on advice of the community.
Usage scenario:
I'll be using my phone mainly for pictures throughout the trip and possibly listening to some music, anytime its not in use, ill be turning it outright off, however, id really like to see just how far i can take this.
Anyone have any other suggestions for longevity?

Don't forget Google Now and Auto Syncs. (uncheck Auto Sync Data in the Data Usage settings).
Check out this thread here for some more suggestions.
I've been able to push it pretty far even with an active internet connection, though most of the usage comes from reading Reddit or forums with Tapatalk. That was on stock with no root access.

It's possible that it will take less power to just put your phone to sleep when not using than booting it up every time you need it. Depends on how often you boot though.

I was thinking that as well, however it would be difficult to find that "mid point" if i had an emergency backup of battery bank to test this theory, i would. However, im going to be stuck in the mountains and would rather have the ability to take the pictures i want rather then pure data log expedition. Great insight/hivemind though.

Based off my experiments, it takes less than 1% of battery to reboot the phone though I would guess somewhere in the 0.5% range. In airplane mode with all of these functions disabled and in deep sleep, 1% would probably get you 6 hours of idle time or even more. Therefore I would only power it down if you won't be using the phone for at least the next 6 hours. Rough estimations of course, I think either way it would be pretty similar.
If the phone is not powered down you might be inclined to use more than you would otherwise.

Unfortunately I do not, just speculation based off what I've seen when monitoring current draw (using Current Widget) and the battery percentage before and after a reboot.
I do have shots demonstrating low idle drain with Auto Syncs and Locations disabled. On average I'd say my drop is about 1% over 5 hours of deep sleep, but it's always hard to tell because there's no way for me to know exactly when it drops without active logging which would interfere with the phone's deep sleep.

Generally speaking a reboot uses ~1% of your battery. If you're locking your CPU to run at only 300mhz I would just leave it on the entire time. Especially if mobile data is off and so is WiFi. Make sure you go into Settings > WiFi > *Touch the 3-dot menu* > Advanced > Disable "Scanning Always Available". I lose about 1-2% in airplane mode overnight over clocked with high quality sound driver from Viper4Android. Plus the Google now hotword activated everywhere but lock screen.
A while back I did a test with my N5 to purposely nerf its power to see how long of a SoT I could get with it. I did pretty much everything you mentioned in the OP. Locked max CPU frequency to match min. Lowest screen brightness, airplane mode, etc. I was able to get over 12 hours SoT. So if the N5 can get 12 hours with the screen on using the same setup you plan in using with the phone getting nice and warm... I don't think a week standby time is too farfetched as long as it's idle most of the time except for pictures. Depends on how much music you listen to I guess. Only problem is even with music saved on the device itself, running at 300mhz you're going to run into skips and pops. Especially when the screen is off. Music playback will be kinda iffy.
Good luck though and let us know how it goes.
Edit: Actually I was mistaken. I just disabled everything like location, sync, etc. Default kernel parameters except switching to ondemandplus governor. This was on an older release of Uber kernel. 12+ hours SoT with ~30% battery remaining!
Here's my post;

You'll suffer Lag I would think with CPU at 300mhz max. And likely use more battery than your saving with the phone struggling to process anything.
May have instability issues too. I'd rethink that.

I agree, but I think that if the phone isn't used at all besides some pictures here and there, it should be fine. If he plans on music playback he's going to have to raise the max frequency, no question. Music playback won't work reliably that low. I don't think lag will be an issue for him considering what's he's trying to accomplish with the phone, but I can't speak to instabilities with 300mhz as max as I've never tried it.

I agree, but I think that if the phone isn't used at all besides some pictures here and there, it should be fine. If he plans on music playback he's going to have to raise the max frequency, no question. Music playback won't work reliably that low.

Currently Using Apollo music player, can confirm Zero issues using music playback, confirmed CPU freq. using cpu frequency app. most of these things are using hardware decoders

But if the phone is sleeping soundly as it should.... The max CPU is irrelevant if not being used. The lag and strain to run processes may hurt a lot though.

You let the music play while the screen was off for a few minutes or did you just play it for a few seconds? I have music stutter on screen off with frequencies higher than 300mhz. I get it with 729mhz. If it doesn't happen to you, awesome. Not sure why though. Do you have time to purchase an OTG charger? Might be worth looking into and they aren't that expensive.

Currently listening with screen off/on full songs. No issues. no time to purchase an OTG charger however :/

Updated main post to reflect newest enhancements.
Trickster seems to pick and choose sometimes whether it wants to listen to me, sometimes CPU freq. on sreen off is changing to 652800 on its own. :/ anyone know of a way to get it to respect my settings?

It can be done

I seem to remember a thread somewhere on xda regarding a CPU's "race to finish". Basically a cpu will work as much as it can (or better said "is allowed) to finish each task after which go to a low power state, like a marathon runner accelerates on certain portions and then "coasts" to conserve energy or a a car running on a near empty gas stank. Since you have a couple of days left I would try raising the frequency (600,800 and 1000) and see what happens to the power drained. It would definitely help with usability, as well as enable using photosphere or panorama ( which take quite a few seconds even at full speed to process) if needed. If the power drain would increase by less than 10% I would call that an acceptable trade-off.
While there is nothing wrong with finding the limit of your device, I think that an external battery pack would be a much better solution. There are ones available for less than $20 that could fully charge your device twice,

I remembered a discussion along those lines, ill bump the freq. to 652800 min max, and update the main post. An external pack would be great, but i unfortunately just don't have the cash at the moment. between the trip and i just ordered a triple monitor stand and a new wifi usb to play with nethunter

This is basically all you need, the phone will idle for a week or so in airplane mode.

Phone idle draining battery.

The "Phone idle" process in this phone is drainage a lot of battery, about 20% average. I understand for Android 6 Google have stricter requirements to list battery stats, but since this device don't have that yet I don't really know what's really causing it.
It's not a big deal yet because the battery life is very good on it's own, so I still have plenty of battery after the end of the day. For now I will try disabling all the gesture features and see if that's the culprit.

I've heard that if you have a lousy LTE signal where you spend most of your time, your phone constantly looks for a better signal and that process drains the battery. How's your signal strength? Maybe try airplane mode and see if that makes a difference.

battery drain in idle is at least 5-6%. noticed that i had battery up in full charge before going to bed and by the morning it was at 94%. no calls/messages/alarms/notifications during that time. however all background sync tasks were running

Not sure whats causing this . Only getting 4 hours sot. Main reason i got it for my work phone because of battery life. Any tips would be great. I have sync on for work email. And lte and almost anything automatic. Had a moto for work before and got 6 hours of sot

I noticed when I turned on Black Screen Gestures the phone drained a lot faster. I turned it off and disabled a bunch of apps and this is what I got so far.

I am getting very good battery life. Stock everything except for root. Black screen gesture on, google now disabled.

When I rooted my phone, I had to "factory reset" (formatted /data and /cache). I am using sim slot 2 only since I don't want to take the battery out to swap sim if needed. I am not using an SD card.

this is mine . do you see all the Awake . its by android system and idle

this is from the battery monitor app

That's strange.. Something is wrong with that graph for sure.. Have you tried using your phone in safe mode?

how do you disable google now anyways. i only have google now cards turn off i cant find setting to completely disable it.

is this even accurate
1000 mah? instead of 3150mah

I am rooted, I have Greenify, Xposed, and Amplify installed This combination seems to make sure the phone goes in to deep sleep now. Using CPU Spy I was able to see that my phone was not going in to deep sleep very much.

You can disable Google Now by dialing the Google search app. Or if you have a back up, you can delete the priv-app/velvet folder.

I am getting big time phone drain and I don't even have a SIM card in yet. Battery graph says the phone is awake the whole time. I had black screen gestures enabled but I'm gonna try to disable those.

My phone standby is about 10% drop per day. Dual SIM standby, one AT&T , one TMO.

It drained mine as well. What I was able to do in order to offset it was twofold Xposed and 'prevent running' app. Then simply a matter of disabling everything you can think of that will not interfere with booting. I can list what worked for me as far as apps and system apps if you'd like. I have total 57 and testing tomorrow more. Just over half are system apps like play store play services google+, etc...
Doing that saved almost enough to offset near 25-30% average. Idle as yours. Next I simply adjusted my habits with keeping GPS off, WiFi on though even sleeping.
THE biggest issue is Adups spyware comes pre installed on it. It collects every letter typed, site seen, text sent..All of it. Using terminal emulator and pm disable works until reboot. Freezing it seems to trigger more hidden like com.fw.upgrade.fota.sysoper to collect. I tell you as well many claim to remove it I have tried 12 ways. It is a battle and 1 I contacted BLU over this to no avail. Second BLU phone and last. Huawei, Samsung and ZTE also have this installed for this phone they are (at least the known ones)
com.adups.fota
com.adups.fota.sysoper
com.fw.upgade.fota.sysoper
There are more but offhand I forget them. *.quicksearch something and what is not stock browser but similarly named.
*.sysoper anything is assuredly as are anything with adups in the name. Use Mixplorer and sqlitedb viewer and go to /data/data find the folders and look at the db's it is everything. Sent to a server in Shanghai every 72 hours or less
