[Q] battery goes very quickly - Acer Iconia A500

Heya,
My Iconia Tab A500 battery goes very quickly, im not even use it much, Im just useing it for 2 hours while im in Uni that's it but still goes very quickly and my front facing camera is just too dark and blurry.
Plz help me out.
Thanks

What apps you running? Is GPS on all the time? You running a different rom or kernel? I don't know what I could do on mine to kill the battery in 2hrs.

Settings - Apps - What process are running?
I test out ROMs while I'm asleep. Go to bed at 100% with tablet on (screen off), wake up and check in 8-10 hours
Only 2 or 3 ROMS so far will be at 99% or 98%.
Most others, even STOCK ones go down to 70-80%. when I see that, I stay away from (re-flash to another)
* Note: if you do the same things for each ROM, you know it's a accurate comparison.
Currently using THOR's ICS v80.
from fresh install (Yes i know it's plain -no bloatware)...
Only 4 Process running.
RAM 180 MB used - 545MB Free (memory -not storage)
even with 25 apps added my RAM is between 205-225 Used - 500-520 Free
Battery Life is OVERWhelming!
STOCK HB starts at about 325 MB - 400MB used (with NEW OS just installed -no custom apps)

Does your battery only last 2 hours? I couldn't kill my battery in 2 hours no matter how hard I try....
Perhaps you have some app that is causing issues, or you have a faulty battery? Do you have a lot of apps open at once? How is your screen brightness? Bluetooth?

I think it cause of GPS and i got more then 80 apps in my tablet

Dude, you go to sleep with tab at 100%. You wake 8-10 hours later and it's at 90-98% (more or less)
And you want to complain???
Android does not sleep. You still have things running that need to run. Clocks, Notification checks, etc. Hell, even the system doesn't sleep as it HAS to do certain things.
When you compare Stock Roms against Custom Roms, a lot of custom roms have custom kernels which will underclock and undervolt the system board, which is why battery power is much better.
If it's using too much battery when you actively use it, it's because you have too many things happening all the time. I have a crapload of things running, including a 3d launcher, and I get about 5 or 7 hrs if I leave it active all the time.

And these 80 apps are probably doing all sorts of active synch's and notifications, gps active and such?
Go to each app, and check settings for them, and turn that stuff off, or set them to a more reasonable level, like every 4 hrs.

Is 180Mb Ram used with nothing installed supposed to be good"?
I get 106Mb Ram used with 45 apps installed, so I'm thinking maybe not?

Way around it
I flashed mine with CWM, and a stock acer rom with root and busybox built in, and got cpu tuner, and when you turn the screen off it saves battery, you can adjust the governor and power profiles and everything, just need root access, works well for me

Opinion about battery life cyanogenmod 5.0.7

Hello. I need an opinion, i've been using cyanogenmod 5.0.7.
Just back to my home pc. After using for 1 day i must say that battery life is a issue. I really dont know what is. I've been monitoring all the apps. to see if there was any CPU change. Is LauncherPro responsible for battery drain?
In almost 13 hours the battery was reduced from 100% to 24% . My settings at SetCpu are:
Usualy have only 2G signal in order to save battery.
Sleepmode 128 as minimum and maximum. In normal use is 528 as Maximum and 245 as minimum ( i tested for 5 hours with 352 Mhz as maximum , anoying that the performance wasnt very good so i changed back).
Stock of new radio roms, have as default 480Mhz as minimum and 528Mhz as Maximum for what i saw in SetCPU last time i used the Sense UI 1.5 Stock by cursordroid. IT lasted me around 1 day and like 10 more hours with same use as this time.
I would request higly some opinion about this, so that i may know what to do in order to have a better battery life.
I used around 3 hours of music daily, near 30 min of internet (it varies according to my needs). Phone Calls (around 1 hour at max). Some text messaging. And 20-40 min of playing games and checking apps for fun entertainement (This i dont do daily but since was todays use i leave here) .
Also noticed as stated above about the Signal reception (reception is in maximum but call gets lost easily compared to a normal ROM and new radio (not sure if is only new radio)). Is alot worst than usual. I dont know the reason. But with sense ui worked perfectly well.
I think these are the most important issues wich must be dealt with in my opinion and i hope next release will be accounted.
Battery life and signal reception or if you can help, and sorry if this is not a issue of the rom, a possible solution.
Thank you!
Some battery saving tips:
- Go into spare parts and make sure the end call button makes the phone go to sleep.
- Turn off market notifications (Go to the market, then downloads, then hit menu and then notifications).
- Turn down the brightness as low as you stand it.
- Kind of an obvious one, but get a task manager and periodically kill apps running in the background that you're not using.
- Speaking of apps running in the background, lower the refresh rate of apps to as low as you can. Or simply turn off background data use and refreshing entirely.
- Turn off wifi/bluetooth/GPS when you're not using them.
- Use as few widgets as you can.

This is plain WRONG.
Do try ADW Launcher instead of Launcher Pro. It won't help with your reception issues though. I had the same problem with CM on old radio. The other was GPS (didn't work).

Apps running in the background = better battery? Please explain.
i'll try as you suggested. it is very important. i'm testing now the port for new radio. Reception is great compared to the one before.
Lets see how it works for now =) I'm waitig for new update seems there is some battery drain issues going on CM 507
Also try using CM 5.0.8 test 1. I've noticed improved performance. I came across one thread that also suggested the Facebook program was causing drain. By turning off all the Facebook sync and notifications, I'm highly improved battery life.

Most apps that are in the background aren't running, they are sleeping and not using any CPU. For continued background activity the app would have to implement a service, which would be pointless for most apps.
I get 10 hours out of mine with complete eclair, and setcpu at 245 min and 614 max...Its stable and I do about 3-4 hours of music, moderate texting, and 115-30 min of web browsing of 3g...Oh and I only have about half signal.
507 was killing my battery... 508 seems to be better so far
actually after a experimenting 508 isnt that great either... it lasted about 11 hours... a listened to the radio most of the day and a few songs for about an hour... one phone call for about a minute... and its dead
the best Cm 5 battery life for me has been test 7...
Hmmm I look at it this way, if you clock to low it will take longer to finish whatever process its doing and will kill the battery faster, if you clock it to you, you will be poring to much voltage towards the cpu killing your battery...Idk if mines is best but its clocked at 614 and has been great so far.
I'm using CM 5.0.8 t1 and battery life is great: 24 hrs+. I DON'T use Facebook, Twitter, SMS or Market update check. I do sync Gmail, contacts, calendar and weather. I do use some internet, not a lot.
Wrong
Never use a task manager. Applications running in the background doesnt mean that they are running. The might be sharing resources with another ( or sharing threads). So never killl apps. Android has its own service manager which tells the phone to run on optimised settings. Killing a process will again require the other app to start again.
Uninstall your task killer and feel the difference

Correct, just like windows, and force closing some apps can cause the o/s to become unstable...

ATTENTION! Xperia X10 battery problem SOLVED once and for all! Not kidding

Hi fellow Xperia X10 owners!
Ive got my device now for 4 weeks and in the beginning my battery only lasted for like ... 5-6 hours max ? I got so annoyed i did some research on how to solve it, and to be honest.. ive seen MANY post and MANY solutions but none of them really worked or they were not explained detailed enough to make any sense .. after many useless tweaks i got my battery to last like 12 hours, and that is by just making like 1-2 phone calls and some messages, nothing more, left aside when i made photo's or used the web... so my device was still useless.
Then i started using "advanced task killer" and the auto-kill feature, but that didnt realy solved much so i installed "task cleaner" but that didnt do much either.
Now after 3 days trying to find out what the problem is, i finally came to the solution !!!
Many post suggest using "advanced task killer" but none of them really gave the perfect settings for it, well i finally found them out myself
The settings i use : Auto Kill Level ==> Aggressive
Auto kill Frequency => When screen off
Security Level ==> Low
And now for the first time EVER! my phone can last like 3-5 days without recharging!
Additional tweaks are: 2G only
disabling WIFI and Bluethooth
disable GPS and positioning
Disabling these 3 doesnt realy make any problems since you can access them quickly by using the "networking widget" so i dont care
also put screen brightness to auto adjust and all these other minor things you hear in all the other posts, i am not going to list them once more.
Ive made some photo's for you to see for yourself
I'm a new user so i cant post links yet.. so you will have to copy it
w w w.photoshack. com /index.php?cat=26302 (kill the spaces)
I'm not trying to fool you or anything, i'm honest
(its in Dutch btw)
Time since last Charge says : 4Hr 14min 11sec
And my battery level indicates 100%
At this moment it says 5hr 9min 10 sec and i just entered the 99% zone
i didnt really made any calls or anything, i just checked once in a while how my battery was doing so it was basically running idle but i am still Very impressed!
I'il let you know how it turns out tomorrow etc, after ive made some calls and stuff
Good luck to all of you and i hope your search to happiness is finally complete!
And yes i'm dutch so dont blame my spelling ^^
Regards, clintax
thx for your info, i'll try your setting now
interesting idea, but I think we need to go through the list of what it is closing down in case you want to keep anything running. I Will test your settings and see how it does.
I was just using Kill level - aggressive with security level - medium and it was doing ok. Nothing spectacular but at least I could go all day without needing a charge or battery swap.
i was wondering. What exactly did you auto kill on advanced task manager?
I keep looking and looking there is nothing particular i want to kill.
I'll try this out and see how it goes by tomorrow. And by the way are you using helix launcher, gde or anything? Or is this the only thing you're doing?
I set the level to medium instead of low, we'll see how it goes.
I've followed all of your guidelines, but when I set ATK Auto Kill Frequency to "Screen Off", it immediately turns the screen back on after turning it off. After letting it sit and naturally time out screen off, it immediately turns the screen back on... Vicious power-draining cycle.
Is there some other tweak that I'm missing in your post?
@clintax, I'm pretty sure that the real reason that you see this improvement is because you have basically disabled all your networking facilities.
I have wifi turned on (never turn off when plugged in), GPS is turned on (which is the best because it doesnt consume any power unless some app uses it), bluetooth is off (but can turn on on request via settings widget).
My phone lasts me over 12 hours, which is sufficient to cover a normal work day, I use it in the metro to read books, I check news and feeds occasionally. I use push email so that I get instant notifications.
Personally, I dont think using task killer applications to kill apps is the only factor in the improvements you report. Usually, whenever I check my battery usage, applications+android system are usually under 5% in total.
I'm pretty sure my battery will last longer if I follow your example, but my phone wouldnt be half as useful as it is now. I really dont mind charging it overnight.
Cheers!

followed your instructions but didnt get help. actually, my major battery drains on radio and standby. the 2 items always takes more than 50% of the total drainage.
look forward to the comments from all of you.
Didn't see any improvements either. I usually get 25h+ without running any task killers or start auditors, with 3g always on and medium to hard usage of the phone, which I'm pretty happy with. So I think its the settings of the data and radio that drain the battery, not the applications.
As a fellow Dutchman I'll share my part
Well I've tried most stuff already on my X10 and the only stuff I can really find that drains my battery are faulty apps (or at least in combination with the X10), GPS and searching for network when I'm out of reach (which is seldom).
I've currently disabled Beautiful Widget using the Startup Auditor, because at some point it starts killing my phone by running 100% and not letting my phone go to sleep. And this is what I meant by faulty apps (or in conjunction with the phone/OS).
3G is always enabled (what would be the use of this phone if you would disable all features which makes a smartphone useful).
Network based location enabled (now using it for the Weather & Toggle app).
No taskkillers running whatsoever.
Running Helix Launcher2 as home with seven screens.
Sending 20 to 30 textmessages, browsing the internet for 30 minutes (half with wifi/ half without), some calls about 30 minutes, toying a lot on the phone two hours plus, some Google Maps navigation 15 minutes with GPS enabled.
This will get me two days of usage easily.
Oh and running R1FB001 at the moment but had these results already with the R1EA016.
.
well yea, i installed helix launcher yesterday but i uninstalled it right away because i didnt like it so much.
Well to be honest, before i used the agressive settings etc on ATK, i used the same settings on the rest of my device
Wich are
-Only 2G
-No WIFI or bluethooth on
-Gps off
-autosync off
-dissabled auto-update, and put it on manual
-deleted the cash of moxier, timescape, mediascape in settings->my applications, and removed there icons from the homescreen
-screen brightness on auto
I suggest you take a look at this video from sony, wich explains it more detailed
(cant post links yet)
w w w .youtube. com/watch?v=P3H--BLPQnI (kill spaces)
and my battery still drained atleast 3-4% hr if not more, it is only from WHEN i started using these settings in ATK that my battery life improved like 500%!
BTW as for what features it kills by doing so i dont know yet, but at this moment everything still works perfectly
At this moment i have 14hr 23min 31 sec and 96% battery left, i'il post another pic for you guys.
Here are the new Pics: w w w.photoshack. com/thumbnails.php?album=10356 (kill spaces)

Well the important part off all this was Security Level ==> Low
it shows you like 3x more things running on you phone then normal, and i just killed them all except: Ignore list= ATK, Xperia Flashlight, Alarm, VizBattery, Handcent Sms and taskpanel, but i dont realy use taskpanel anymore
I am still trying to find out what it actually kills in particular but i heavent found any problems yet

I had two "battery cycles" where the battery lasted 48 hours with my normal usage (Moxier+Gmail in push, 3G data, no WiFi, some Bluetooth while driving the car, no GPS). I noticed that because I usually have a 24 hour duration, and at the end of the day, when I put the phone charging while I sleep, I still had more that 60% of the battery instead of the usual 15%! So I decided to not recharge overnight and so I get about 48 hours both times.
The third cycle lasted even more, about 60 hours!!!
However, starting from the fourth cycle... back to 20 hours, or even less... I have not changed anything, I'm not even using task killers... I really don't know what is wrong with this phone (the problem is not the battery itself, I tried with 2 original SE battery + the mugen).

Wow, the performance is just amazing. I suggest you start to use the phone instead of keeping it idle. Then you can share with us how the battery performs, thanks.
Which version of Advanced Task Killer are you using? as i have just checked mine and do not have the option to kill when screen is off
I have version 1.7.4 build46

Advanced task killer v1.7.9 build 57 (directly from market)
Ok, so with the settings I used over night, I had a 5% drop over a period of 7 hours sitting idle.
Auto Kill level - Safe
Kill Freq - When Screen Off
Security level - Medium
BT, WIFI and APN - disabled.
I had a 1% drop in like 6/7hrs.. fell asleep whilst using xda, 3g was still running an all..
I just use taskpanel
Wifi, gps, bluetooth & auto sync off
also Adw launcher
Edit.. Firmware 016 (only cause I can't remember the rest lolz)

Longer Battery Life!

hi everyone,
i just wanna share my experience with my Samsung Galaxy S.
i have finally managed to keep the phone running with "normal phone usage" for more than 1 day
it is true that the multimedia features usage was to the minimum but still
2 Days, 16 hours and 43 minutes is an excellent number,
and still i have 15% remaining in the battery!!!
Check the screenshots below.
All what i have done is:
1- installed Voodoo lagfix
project-voodoo.org/download
2- installed Advanced Task Manager (ATM)
getandroidstuff.com/advanced-task-manager-android-download-v50/
And make sure to enable the Auto-End Running Apps features in ATM, i have used the 30 minutes frequency.
i am still unable to believe the difference that i got from this combination.
Voodoo has really fixed the lag issue and apps are running so smooth.
and with ATM installed the battery life has reached unbelievable numbers.
the installation for Voodoo was so easy and no complications, i have just used the update.zip file and it was so fast and easy.
check this yourself and tell me what you got from it.
cheers.
EDIT:
i forgot to mention that i am using ADW.Launcher instead of TWLauncher.
That's nice.
My record with light usage was 4.5 days.
In that particular case, I still had 50% after 3 days but made a lot of calls on day 4 so the battery went down quicker.
Key setting is to switch the phone to 2g when not needing 3g and also turn off the internet connection through the mobile provider and only use WIFI where available.
Very nice usage, but do you have push email active?
Congratulations abuatwan but i still think you could get longer from your battery. You say you have Advanced Task Manager running and set to start up every 30 minutes.
That costs power to start that up (as does any app) and when its killed whichever apps/processes its deemed to, if they start back up...well that's even more power lost lol
Android has its own task scheduler/killer built in and really all you are doing is battling your own system.
This will explain in much more detail, even if you don't understand everything mentioned read on and try to take in as much as possible.
http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
I do agree though that with the galaxy, something needs to be done as it does in a way run better with a task killer (not counting the battles and power costs)
I use a free program called Auto Killer Memory Optimizer which tweaks androids built in task killer meaning you use your system as it should be
I've had mine running on 'moderate' preset setting for 2 weeks now and i wouldn't dream of installing any other task killer

The default setting for killing empty_app processes on Galaxy S is 48 MB. The moderate setting on autokiller is 40 MB, so you are actually *decreasing* the memory tolerance, making the memory management worse! I agree with you about the article, but with a strict setting you will see much better performance, try it.
My SGS keep 3 days max with normal use with disable the data connection with GSM and 3G
I do 2 days with browsing and stuff, seems my battery drains less quickly on wifi then it does with 3g or H =\ killing stuff with ATK is pretty handy as some stuff that i never use don't really mater to keep running in the background.

no, during this period i have turned it off, actually i have turned off the Auto-sync option.

great,
if i can just change the default likker setings, i believe that will save lot's of battery
Definitely i will install "Auto Killer Memory Optimizer" and will try both profiles, the moderate and the strict.
Thank you
I do get this with my normal usage, 2 days and some hours - can't remember exactly. I have wifi on constantly, 3g when outside, autosync and push always on, autobrightness, no task managers or lag fixes.. Just stock JM2 :]
I have never managed to get more than a day's usage out of my phone. Today my display has been on for 1h37m and the phone has been off the charger for 5.5 hours, my battery is down to 66%.
good luck, in 3 weeks or so you'll need to do a factory reset because the SGS software/file system is a P.O.S

Ahh well that's new to me, Thank you Tyxerakias. I do wonder what else this app is tweaking then because using Super Manager memory widget i had noticed that i would get slight lag when swiping screens if the reported memory was showing around or below 70mb. The 70mb figure might be wrong as i use a lagfix but the point is that to me around 70mb showing = lag. After installing Auto Killer Memory Optimizer i would sometimes see as low as 50mb but still no lag. I got rid of the memory widget after that as it was just displaying useless info and taking up screen space.
I would be tempted to try the strict setting but my phone honestly flies on moderate and ive also heard if you set it too strict then it can end up killing off things like the clock which means your alarm will then fail.

why 3 weeks? are you referring to the Froyo update? and what is P.O.S?
Personally i wouldn't mind doing a factory reset if you ARE meaning for Froyo as flashing Froyo will reset it anyway...2 resets is no more loss than 1 reset if you are backed up and ready to flash

Personally i wouldn't mind doing a factory reset if you ARE meaning for Froyo as flashing Froyo will reset it anyway...2 resets is no more loss than 1 reset if you are backed up and ready to flash

lol ahh i get it now, he means the file structure in the Galaxy. Samsung chose to use their own rather than a proper linux structure and i've seen many devs also saying how it was a very bad choice.
Well i've had mine for over 2 months now and no loss of data or anything yet so its fingers crossed here lol..........i will be backing important things up as a precaution too
Yes, that app is useful and i am confident you have noticed that
I don't use a task killer, they drain the battery.
I'm pretty sure you would get the same battery usage with screen on vs. screen on and movie playing. Playing a 2h movie drained my battery for 25%, screen on for 2h was about the same so...
I just use Juice Defender ultimate just to be able to select a few features:
- Activate Data/Wifi for 5min every 2h (would be better every 4/6hours but whatever...)
- Data / Wifi off when i sleep
- Leave data/Wifi on when the screen is on
Basically, my phone only syncs / uses data when my screen is on (or every 2h just to push emails if needed)
I noticed that this really really helped me. 3G and screen on really kill your battery

[INVESTIGATION] Battery drain bug in 2.3.4 (JVP build for now)

It seems that our beloved Samsung did it again!
Now we can enjoy a fully functional, long waited, Gingerbread 2.3.4.
Although some sources say that it is only a leak, the JVP build seems to behave really well, according to the reports of many users.
Gingerbread 2.3.4 was build in order to fix some Android bugs and make the interface even faster. We have seen that the second task is a success, the user experience and crazy Quadrant scores being the best witnesses. But what about the first task, are there any android bugs in this build? Maybe we could find out together.
The key purpose of this thread is to find out if that Android OS bug, which made Gingerbread users a hard life, is still present.
You can help this investigation by keeping an eye on the battery stats and reporting the consumption (in percents, of course) of the Android OS. It is even better if you can add some screenshots.
Please don't forget to mention:
- The ROM and kernel you are using.
- Some apps or games you are using (known to fire this bug on previous builds).
- Whether you have autorotation on or off (some users reported they had no drain if kept off on 2.3.3 builds).
- What type of usage you applied to the phone (not really necessary, only you are kind enough).
If you have any kind of suggestion regarding some modifications for this thread you are welcomed to post them. It will helps us become more efficient.
Thank you very much for your effort!
EARLY CONCLUSIONS*:
- Battery life is indeed an improvement on JVP 2.3.4
- The Android OS bug is less aggressive. The reports show a maximum consumption of approx. 20%. We can't say for sure if we can talk about a bug anymore. Anyway, the drainage is not so bad, comparing to 2.3.3 versions.
- The Android System consumption is a bit scary (15-20%) especially after a flash. However, it tends to stabilize in time.
- A clean flash, factory resets, avoiding apps restoration with Titanium or similar, reducing consumers when you don't need them always helps. With or without battery draining bugs.
- JVP is a better alternative for previous versions due to improvements for battery life, speed and stability, even if it's a beta release. So you should go for it, it really is an upgrade!
*The statements above are based on reports and poll results collected until now and they may change. I take no responsibility if you will find those informations incorrect or incomplete. Flash JVP at your own risk, you could loose data or brick your phone, although there aren't reports that say that. Follow the instructions and you should be ok!
is this a new craze insted of train spotting or stamp colecting ....battery watching ....most of us have got a life and have better things to do then watch how much a battery uses ...do what i do charge the phone and enjoy these phones do use loads of battery
Updated with 2.3.4 I9000XXJVP,CSC = I9000OXAJVP and kept it on without sim and without even touching but fully charged. The battery life was just for one and half days.
Android OS running at 3%
using Damian's GTO Alpha kernel for JVP and Brotuck's gingerMod ROM.
Autorotation off.
Consistent q scores in the 2600 range, phone running very smoothly and very fast in daily use (internet, twitter, pics, camera, messaging, phone), 130+ apps installed, no issues. Seems a much better base firmware than any of the 2.3.3 variants.
It's a bit early to investigate this stuff.
Wait for Samsung to release 2.3.4 sources and devs to make some stable kernels based on this.
Until this time many stuff can be broken (well, you're free to beta test though ).
batery is much beter in 2.3.4
no since i flash JVP 2days ago!

Keep in mind that after a reflash the battery life will stabilize after a while.
In my opinion, the cell standby may be the cause. If left without SIM, Airplane mode off, your phone will continue to search for signal and this really drains the battery.
If you can make a test again, check the battery usage and post your conclusion.
Thanks for your contribution!

This kind of activity is normal in community, especially here in XDA.
It will be useful for those kind of people who don't like to experiment in order to find some answers.
We could do like you but, what if we need to charge it again, after 8 hours, without using the phone?
That's why this "new craze" exists, because we want to avoid that kind of problems.

You're right but the 2.3.4 concentrates on fixing bugs, so even in beta stage we should see some changes.
Anyway, the thread is intended to test the firmware regarding this problem, so it can become an indicator for people asking weather they will experience this problem of they can enjoy using their phone without even thinking about this.

I must say that 2.3.4 battery is performing better than 2.3.3 so far.
After 11 hours with gps and auto rotate on, battery still have 30% of juice left.

Comming from Froyo JPY to stock deodexed JVP, I have noticed a higher battery drain.
I lost 13% overnight, I had 21% battery use on cell standby (6hours of use). and I noticed something very strange, android system has a 18% battery use with only 5 minutes running, WTF???
I'm using stock deodexed rom from ramad, Dark core kernel and screen off animation. that's all I've changed to this rom, no games, and a few apps like titanium backup and atk.
When I tapped on the android system there was a huge list of included packages, I will list them here, maybe one of them (or all together) is causing that huge battery use:
com.samsung.InputEventApp
Service mode
Software update
Google Backup Transport (actually, I turned off google backup, idk why this is here)

It seems that you have a normal consumption on Android System. Also that app list is present on every ROM which has all system apps. On lite ROMs you can get a smaller list, because some of those apps are removed by the chefs.
Maybe your network coverage is not that good
After a flash, the battery needs stabilization, until then it can drain fast. Try to recalibrate it. Please tell me if you need a good guide.
Try a lite ROM. Maybe you will experience a good Android System consumption.
Thanks for the feedback!
Look at the poll results so far 72% say they have no battery issue, so it must be the apps on your phone that are at fault for any unusual battery drain.
Look at your own apps first before you blame the rom, mostly it's not the rom that's at fault.

When you're not really using your phone, Android System will have a higher battery use percentage, because nothing else is using battery.
Long periods of idle, you will see higher Cell Stanby and Android System percentages.
The more you use the phone, those percentages will lower.

Good job! Enjoy your phone!
turn off data connection or wifi when youre not using them
and it will least even longer...
This is what i had with the previous JVO (2.3.3) and not using any task killer anymore. I moderately used the phone, made some calls, wrote some SMS, had blutooth on in the car, listening mp3. Ah, and i set display brightness to "auto" always, i don't use the manual setting with lowest brightness value anymore.
But i also can get the battery down in less than a day...
I'll give the new 2.3.4 a try.
It's funny to see that there is always somebody who needs to torture the board with reinventing the battery wheel. Strange battery behavior usually shows up (and is often dependent on them) in threads with special roms or kernels. The only thing this thread will brings us is more of the same on how to save juice if you don't want to fork for a larger/extra battery.

Battery tips and tricks

Hello guys,
I've been having problem with regards to battery life. I am not sure exactly if there's a problem but seeing from other peoples posts/experiences/videos it seems like my note has a very low battery life (about 10-15hrs battery and about 3-4hrs on screen time) So I've decided to start this thread that would hopefully help me and most people that are also experiencing/or just simply would like to improve their galaxy notes battery life.
This is where we can all gather and put together informations on how to do so.
- Please post any helpful tips and tricks.
- A list of bloatwares that are safe and not harm our note to remove/freeze.
- Apps that can help save and/or monitor battery consumptions.
- Apps that are a good substitute because they consume less battery.
- Your personal settings/kernel/roms and how you achieve an awesome battery life.
- Steps to properly calibrate battery.
- Anything else that would help.

The list of removable apps.
Even more apps can be removed.
InputEventApp.apk
SMTSetup.apk
DataCreate.apk
PCWClients.apk
PopUiReceiver.apk
Preconfig.apk
SMTEngine.apk
ShareApp.apk
ShareShotService.apk
SyncMlds.apk (spreadsheet says removal causes battery drain but it did not)
and all test mode apps
Before you remove tracker engines and remote control make sure you have not signed in your samsung account or you'll get force close errors. Best way is factory reset and remove apps.

Directories that can be removed (this won't improve battery though)
Hdic from System (104MB. I deleed it and had no problem. May be its needed for Samsung Voice)

Use anttec app manager/ root explorer or your favourite file manager.
There are quite a few system apps that you cannot freeze, but still pop up when not desired. To stop these wasting my battery, I use Autorun Manager Pro to disable all their 'receivers' (these are events they listen for, and start up when the events occur).
Generally I find that they rarely start after that, and only when I use an associated app.
This is the way I deal with those apps you really do need, but do not want running all the time.
Aside from that, I am pretty ruthless about freezing apps using Titanium Backup Pro.
To see what is waking and/or using CPU when the phone is not used, I use Badass Battery Monitor.

To preserve battery during my day, I use Llama (Location Aware Mobile App). It is very versatile, but can take a long time to get the hang of. Essentially this replaces apps such as Juice Defender if they do not work for you (as they do not for me). It is a manual process to set up, but gives you much more control in many ways. Here are the things I use it for to help extend my battery life:
Manage my WiFi
When I am at home or at work, I get it to turn on my WiFi. This saves leaving it on all day wasting juice when I am out. I get it to turn off the WiFi 1 minute after the screen is turned off, and back on again when the screen is turned on and I am not at home or work. I find this far more effective than the built-in 'sleep when screen is off' which often does not work at all. I stop it turning off if I am using apps like Internet Radio, too.
Manage my Mobile Data
When I am at home or work, I turn off Mobile Data. This prevents apps seeking a connection and getting 3G (etc) when my WiFi is asleep. Saves loads of battery, as well as mobile data allowance. I could turn it off when the screen is off too, but when I am out and about is when I most need alerts, rather than when I am in front of my PC, as I am at work and home (sad but true). It could be a bigger battery saver like that for many users.
Screen Rotation
This is quite a drain, small but steady, and frankly I like my screen to stay still. I find it irritating when lying down to have it jump about, too. Certain apps need / prefer landscape, so I just allow rotation when these apps are being used. It then turns off when they close. A very neat solution, but a bit of a pain to set for all applicable apps. There may be separate apps that do this for you (I like having all the control in one app).
Sounds
I make all my sounds very quiet at work, and medium at home, and loud & vibrate when I am out. This saves manual messing about. Probably not much saving.
Brightness
My next project is to adjust the brightness of the display according to location and time. Probably a lot of potential saving, but it may be too difficult to set and may override my manual settings, eg when the sun comes out and I want it brighter. I'll see (and update this if I do).
Battery Level
I use this to kill everything except phone use and turn the display right down when the battery hits 20%. The phone can last a heck of a long time like that, as much as two days. I have had a Note not being used last for 10 days, so I expect a 10% per day drain without anything running. A potential life-saver (literally, perhaps).
Sync Apps on Charge
I start up all apps that sync over WiFi 1 minute after starting a mains charge. I do that every night, so all my syncing apps will not waste WiFi energy when I am at home or work.
OK, so why do all that? Why save all that battery?
Then I can play games and listen to books & music ! ​
---------- Post added at 08:58 PM ---------- Previous post was at 08:51 PM ----------
I also use DroidWall to stop any apps except those I allow to use Mobile Data or WiFi. This can save a lot or wasted battery in my experience.
I also feel naked without my firewall. It was the main reason I had to get Root access to the phone.
With JKay mod you can have lower autobrightness profile.
Thanks guys for helping out!
IMPORTANT: I have tried Anttek and Gemini to freeze apps. However, I couldn't unfreeze/defrost them afterwards. The app would let me click unfreeze/defrost but I still couldn't see the apps even after a reboot. I just want to point that out based on experience because I froze market and I couldn't get it back lol.
- Apps that can freeze other apps:
** Titanium Backup PRO
** Anttek App Manager
** Gemini App Manager
Someone correct me if I'm wrong about unfreeze/defrost.
it's useful,thank you so much guys!!!

All oyu need to do is turn off "3g" mode and use the device with 2g.. aka gprs and only turn on the 3g when you need it.
Now I have 36% and I use my Note since 2 days 11 hours and 36 minutes but my record is 3 days 15 hours and 47 minutes )))

Another tweak is underclock and activate system power saving mode.
Max 800mhz is sufficient to surf internet, check emails and sync etc.
My battery is draining faster than normal after recent update. I hardly used much today and battery usage show the following uses.
Display 31%
Cell stand by 21%
voiced calls 18%
phone idle 13%
forgot to mention but I also use the system battery saving option ) with go laucnher ex no lags at all btw my screen on time is not so much becouse I use it mainly for listen music etc

I forgot that. Yes is do undervolt on the most common settings, ie 100, 200 and 1400 MHz. The CPU rarely goes to the others, but I am on the Abyss kernel. Franco may be better.
My CPU does not work at UV less than about 50 mV under standard. Some can go much lower. The trick is to lower it, and then use it for a while. If all is well, lower it again. Repeat until you get problems, then raise it at least a notch, maybe two (to be safe).
I use ROM Toolbox for this, although I used to use CPU++ (I prefer all my tools in one app is all).

There are definite disadvantages to this. The logic is that the work required is required. It is fixed number of cycles. Under-clocking merely makes the work take longer, and the CPU spends more time working before going back to a rest state, where it uses much less juice.
Basically the benefit of battery saved by running at 800MHz is nowhere near the cost of running the CPU for 150% of the time. Rest states use a great deal less battery.
Having said that, I set my CPU to under-clock to 500 MHz when the battery temp reaches 60 C. I figure it must slow down at that point!
