[Q] Custom ROM´s and battery drain - Galaxy S I9000 Q&A, Help & Troubleshooting

Hello fellow Galaxy owners,
I have been installing various custom ROM´s for about 2 months now, so I guess you could still call me a beginner. Recently it has been difficult to keep up with all the latest and greatest advances in kernels and ROM´s. Being a father I don´t have as much time as I used to, to read through the mountain of information on the forums.
It is for this reason that I ask for some simple advice. I have found that Hamster, Instanity and DocRom ROM´s are all very fine pieces of work and they are blisteringly fast. The GPS is fast, the themes are epic but alas the battery life is pretty bad (well for me at least).
I must admit thought that I am obsessed with my phone and I use it constantly to read the news, check emails and stream internet radio while I am driving in my car on a daily basis.
I currently have DocRom slim V3 installed after having done a complete fresh installation. But despite being fast it seems to be very hungry on the power consumption.
Do I need to cycle it through some complete battery discharge cycles and fully charge it, then reset the battery stats in CWM recovery? Does it need some days to settle? Or should I flash different Kernels and see which one gives me the best life? If the latter then which kernel do you recommend for JPU?
Thanks in advance!

Same here
With 3g my I9000 die after 10 hours!
With 2g die after 14 hours!
With data network mode deactivated die after 30 hours!
I don't know if changing baseband or kernel will help or not!
BR

I'm having pretty good battery life without any network and LiveWallpapers turned off... just simple black screen it stayed ON for 4 days with some WiFi surfing, PDF reading and music listening player/online radio. So I guess network is draining the most.

DocRom V6.2
I just installed Doc´s ROM v6.2, and it has greatly increased my battery life.

Great to hear this!
I don't know if this is your case, I used to have the beautiful widgets weather widget on my home screen, and after soem time I realized this app was constantly refreshing and consuming LOTS of battery.
If you have it, removing it will increase your battery life too.

I have same problem,i do have the beautiful weather widget installed and think it looks nice on home screen,maybe this is the batt killer??
What other programs does the same? I like the watch and weather widget to be shown..?

[Q] 2.2 Froyo update, battery life lost

I have not yet updated my Captivate to 2.2. Reading posts in regard to the update I am very bothered by a common complaint that battery life has just died. My Captivate has excellent battery life using it fairly heavily over a 1 day period. I charge it every nite. Also, my GPS is workng fine in 2.1. So am considering not updating it due to the problems I am hearing about.
Anyone else have input on battery life after the update??
I went from STOCK 2.1 to Cognition 4.1 (built on Froyo 2.2) and my battery life is about the same. My usage varies wildly from day to day, but as best as I can tell, overall battery consumption is about equal.
I wonder if the people complaining about battery life have set up their phone "post-update" with different apps or turned on "apps syncing background data"...
Battery life did reduce on 2.2 but it is obvious in my point of view. But its not too bad either.
it's about the same, i upgraded to stock 2.2, feel no difference on the battery life. moderate usage last mine for about more than 24 hrs, u should update to froyo for you to experience it.

I upgraded Stock 2.2 end of Feb and noticed a big drop in my battery life the first week. But just reading above, i did turn on "apps syncing background data" so i think that's my problem. Just turned that off so we shall see...
Let your phone go through a week or so recharging cycle before judging its battery life after a ROM flashing. You just lost all your battery stats when flash a new ROM. Your phone/OS has no clue how your battery will operate until it has time to learn or you manually calibrate it.
For what it is worth, my battery life is about the same or slightly better than leaked 2.2 ROM as well as 2.1 ROM. No big changes.
My battery has been about the same since the 2.2 upgrade. At first it felt like my battery was draining quicker but I also noticed I was playing with more phone more. The screen is the biggest power drain on the phone so just playing with menus and looking at new settings can cause a small dent.
Give it a week or two after upgrading and you'll notice it'll be about the same. Unless of course you have more accounts or programs syncing data in the background.
Why upgrade to 2.2
Thanks everyone for the input. The more I read and hear the more I am leaning toward not upgrading to 2.2. On different forums I am seeing and hearing problems with battery life and some saying about the same battery life. Also, seeing GPS not being fixed or going from working ok or good to not working so good. Right now my phone does everything I want, GPS works really good, email works fine, internet works fine, battery life is outstanding, mp3 works great, screens all are clean and to my liking, I have an easy work around for turning off 3G and one tap returning my volumes to normal after using a USSD code.
REally cannot see any advantage to upgrading and risking introducing a problem I don't need. The list of new features really does not thrill me.

2.2 ROM is a big step forward, not backward, IMO. Sure it didn't solve GPS issue but it is not making it worse either. GPS issue is purely hardware issue. If you have a good one, it doesn't matter which stock firmware you use.
I just can't see any disadvantage for upgrading (other than slightly more difficult to root or unlock, but not impossible). Battery life thing is as I mentioned above. You will see all kinds of complaints (either dain too fast or too slow) after a new firmware comes out, any firmware. You don't know what you're missing until you upgraded.
I noticed a big improvement in battery life. Sometimes with light use it will last up to four days, whereas before with 2.1 it would putter out after maybe two days.
GPS isn't fixed, but drop one of many GPS fixes in and it will get somewhat normal performance.
Wifi sleep policy
You may also want to check the Wifi sleep policy after the upgrade to Froyo. In my case, the default was "Never sleep". Changing this to "When screen turns off" improves battery life on 2.2, as it does on 2.1.
Just my $.02 worth.

I'm on stock 2.2 since the day it came out. My battery life is actually trending worse day-by-day. I did a full battery clear/reset this weekend and after 4 days I'm finding battery life is not improving at all. The degradation from stock 2.1 is significantly noticeable to me.
For the first couple of days post-update it seemed actually to be better, but got worse and worse, to where I was lucky to find the phone working 12 hours after disconnecting from the charger @ 100% ... even if I hadn't -touched- the phone during the day. My applications loaded are virtually identical to before.
I did have Background Data on, so I've just disabled it, but was this option not in 2.1? I know that Google Voice, etc, were doing background syncs in 2.1.
It can't be WiFi, as for the last 2-3 days I've kept WiFi turned off. However just for sanity I did adjust the sleep policy.
I'm wondering ... my battery woes seemed to start when I hooked up my Microcell. Could having a strong 3G signal so close to the phone actually be causing problems?

That might be your problem. I don't know. I know 2.1 doesn't work very well with microcell either.
Yep. I'm pretty convinced it is the microcell now. Phone works great with it from a call/data/signal standpoint. However after unplugging my microcell last night, charging my phone to 100%, and then letting the phone discharge normally with no microcell ... I'm now 10 hours later and have an almost full battery.
Sad, because our reception here is so spotty that we lose calls and data regularly without the microcell. My wife says her phone charge has been pretty normal, so I'm getting ready to move the cell away from my desk and see if distance helps the story.
So, as far as this thread is concerned, my results for 2.2 and battery life are great ... better than with 2.1 ... just don't use it with a microcell.
Froyao 2.2 Battery Usage Dillema
I see no significant or excess battery drain while riding the KB1 over the JF6.
Just a thought for those experiencing excessive or significant battery drain. KB1 loads some new features and new additional bloatware that loads on boot and runs as a service, process and both.
If you're familiar with poking around your system settings and understand what doesn't need to always be running in the background, or what doesn't need to load on boot, you can simply kill the process and even alter the way a certain application handles on boot.
By killing many unneeded or unwanted processes at boot time, it will significantly save you hours upon hours of battery life in the longer scheme.
Another FYI, Lithium Ion batteries have memory. You need to train or retrain the batteries memory over time in order to sustain a longer life for it.
Tips:
Don't continually through the charger on your device after minimal drainage. Let the battery run down before fully recharging it again.
When flashing to another ROM wipe your battery stats.
When flashing any new code to your device - a few forced charge deaths to purge the battery and reset the memory again prior to recharging may be a good idea...
Hope this helps...
Peace-

Poor Battery Life On Overcome Jupiter

Hi,
I don't have sufficient posts to be able to participate directly in that forum, so have no other choice but to raise my queries here.
I've just flashed over from Overcome "Hermes" to "Jupiter". All's well except that the battery performance is quite drastically affected for me.
I've been reading the improved battery life "Jupiter" gets over earlier versions of the Overcome ROMs, but I seem to be experiencing the opposite.
Already did the batt stat wipe via recovery menu. Do I need to so call "run-in" before it reflects correctly? Even if accuracy is one thing... but dropping 3% just on bootup.... is this typical of an uncalibrated battery?
Appreciate any advise here on what I should do. (Apart from a fresh wipe install )
Thanks
I appreciate the enthusiasm these coding geniuses have in rolling out update after updates in the ROMS yet I am apprehensive about the effect of these frequent flashing on the Galaxy Tab components itself. This includes the battery.
My job involves electronic repair and there is a so called number of hours before an equipment goes for a thorough check(preventive maintenance) say for example 1000 hours on a meter. Unfortunately the galaxy tab (or any tablet) does not have this. So if you frequently do a flashing on your tab you subject the electronic components to unnecessary stress,thereby affecting the life of the components like the battery.
In "normal" everyday use of the tab you will seldom do any restart/reboot of your tab,yet in flashing ROMs as many as 3 reboots is needed. As I don't know how to measure the surge in current during reboot, I can just imagine how high an initial current during startup is generated, thus putting a big strain on the battery.
Unfortunately the battery is not user detachable.
There was an author here in XDA describing himself/herself as an "flashing addict"(or something similar). I would like to appeal to everyone-please don't be a flashing addict.

According to the Tweaks section at the team overcome website, it will take several charge cycles before you notice an improvement after the stat wipe. Try giving it a few days before going any further.
PS Not to question your ability to follow instructions (sometimes we miss things) but did you charge to 100% with the tab off?
Yes, I did charge to 100% with the Tab off.
Now upon reading the instructions once more..... I might have conducted it slightly different from the written procedure.
I unplugged the Tab from the mains, then only booted up and wiped the batt stats before re-booting. Hmmm.... maybe I'll go try booting up while still plugged into the mains, do the batt stat wipe, and re-boot. (all while plugged into the mains). Then only unplug the charger.
Wonder is there any diff in doing so.....
Would definitely try re-doing it with the tab plugged in while doing the stat wipe. And if it doesn't seem to fix it, do go through a few cycles before reverting back to a previous ROM.
It's important to completely drain your battery before recharging it to 100% in order to complete a cycle.
Hope you fix it. Battery life results vary between tab's even if they are used very similarly, I'm running the OVERCOME Jupiter ROM with IMPROVED battery life. I keep my Bluetooth, Wifi and GPS on all the time. I also flash quite often and have not seen a decrease in overall battery life. It seams that each tab is a bit different, hardware wise, than one another. Everything from battery to board it seems is slightly different coming out of the manufacturing process.
Thanks. Will try that out.
But it just seems strange coming from Overcome ver 1.4 (Froyo) which had no batt drain problem.... to Hermes which was better in batt performance.... to Jupiter which I'm experiencing heavy drain.
As I did a NoWipe install, all apps and setting are similar (except the new market app).
I was able to run 2 movies back to back (about 3 hours total) and still have at least 40% life left (usually about 45 to 50%). Now on Jupiter, just fiddling around testing the various features for functionality, plus maybe an hour of NFS (total about 3 hours as well).... the batt drops to about 10% life.
Anyway, I'll re-do the calibration and and give it some time to "settle in". Hopefully, that is all that is needed. (I would hate to have to do a full wipe install... and re-installing all apps)

As mentioned in the Tweaks section, perform the Stat wipe and then two full recharge cycle
recharge to 100% (while the Tab is closed) then drain the battery till it is off then repeat the cycle and you will enjoy it man
Please tell me if you need anything

Viewed purely from an engineering perspective, I'm unable to see any significant connection between the flashing of the ROM and a degradation of battery capacity. Further, in the event that the TAB was connected to a charger during the flashing, I can see absolutely no connection at all! Please help me understand your logic.
Ok Back on topic. PCdumb (dude what's with the username lol). Check your app list. It could a new app you or an old app you updated or an app you didnt use before but you use now that is being a battery hog. A small trick I learned is checking apps running services in the background. Go to Settings, applications, running services and check (why is skype working after Isigned out its not a battery drainer but I hope you got the picture).
Thanks for the advise. That was one of the 1st few things I did to check that there's nothing out of the ordinary running in the background and taking up the juice.
Mine's actually draining alot when in usage. Not too sure about when in standby.... will check later.
If after a few charge cycles and the drain is still bad, guess my only next best option is to do a full wipe, re-stock and re-install.....
I did not get any effect from Battery calibration. As expeced. Anybody did actually?
The background services instead might have an effect on power consumption, I agree. But needs numerous testing...
Batt recal did not give me better battery life. There's no difference in the battery performance after 3 recharge cycles.
My tab can at most get slightly more than 5 hours of continuous usage compared to about close to 7 hours on hermes. This is when i dial down the OC from smartass mode to conservative and also put the min freq to 200 instead of 400 which was the setting i was using all the while.
Doesn't seem to be anything else running in the background. On standby overnight, i only lose about 3% which is not too bad. But when in use, that's where the Batt drains fast. Just for comparison, i only lost 1% at most for overnight standby of about 7 hours when running hermes.
Guess I'll have to live with this if i want the speed and smoothness. Still contemplating whether to restock and do a clean flash.

If you want to confirm that JUPITER is the reason that you are experiencing poor battery life, try re-installing a previous version that you feel worked better for you. Maybe reverting back to a previous version may yield better battery results, and I sure hope so, this way you will know if it's the ROM or other elements affecting the abnormal battery drain.
If you do see an increase in battery life, try flashing JUPITER again, see what the results are. I don't know if flashing and re-flashing will have a negative long term effect on your SGT, I know that I flash every time a new release is out (Stock safe, cooked ROM, Kernel) and if i'm not happy with the release i go back to a proven one by flashing another three times (stock safe, cooked ROM, Kernel) and so far I have not had any (knock on wood) abnormal battery activity.
It's worth giving it a shot (if you haven't already).
EDIT: I know, I know the proper sequence is stock safe, kernel, rom.
after week of using the Overcome ROM i can confirm that the battery performance is between 85 and 90% from the Orignial stock ROM performance
No problem since this is normal as we are using a cooked ROM

I do get 4 to 5 hours of continuous use with overcome Jupiter, mostly browsing the web over
WLAN or umts. Hermes release didn't gave me so much more juice, probably 5 hours.
In the background I have emai push, contacts and calendar sync and some instant messaging apps, if I switch off all that I might get an hour or so more.

Wow, maybe your tab is one of the ones with a battery from the bad batch, and it's finally on its way out. I upgraded from the stock AT&T Rom to Overcome Jupiter, and on Airplane Mode with all stock settings (no overclock or undervolt), mine only drops 1% in standby over 14 hours and I can get about 5 hours of video watching straight with the brightness on max before it dies!

I also been experiencing a major increase in battery drain even after doing a couple wipes exactly according to the tweak guide. I went from about 24 hour normal use down to 6-8 hours normal use.
Checked the services as per your suggestion above and found a couple major battery drainers running. Skype and Yahoo but also Google+. What I dont understand is why Skype and Yahoo would be running even though I had not started either since at least several re-boots ago. I had Skype and Yahoo installed for quite a while Google+ is a new one. Anyway I killed all of them and now and will see what happens next.
Not sure thought that this is all there is to the issue. Recahrging is finiky as well. I can turn off the tab and let it charge all night just to find that it charged to about 70% if I re-plug it might charge to 90%-95% and then if re-plug it might get to 100%. The drain from 100% to 60%-70% is extremely fast and still quite fast from there. On one occasion after complete drain I couldnt get it to start charging at all for about 5-10 minutes. I was checking power, cables, connections and starting to panic when all of a sudden it started to charge.
Any advice on possible reasons or solution woud be appreciated. Not sure I want to go beck to stock ROM and un-root just to take it to service center for repairs.

battery saver

hi, currently i am on darky rom 10.4.2 xwjw1 rom... i have tried different modems on it.. i am happy with the rom but only problem is battery.. i am not happy with battery life.. will going to semaphore kernel will help battery life??? or give any other kernel or rom that gives me more battery life like upto 2 days... if performance degrades little than its ok with me.. is there any hack or scripts which will improve battery life??? battery juiced a lot when using 3G.. please help me guys... any good battery saving ICS rom will also do..
With Darkys i had the "best" battery with XXJVQ, Semaphore and turned off 3g. Just had a widget to toggle 3g quickly. That just saved 20% a day for me.
And i know thats not exactly that what you want but moving to ICS increased my battery life pretty much

thanks for replying.. but i use 3g internet and i do switched it off when not required.. and i am ready to move to ics rom... which ics rom are u using??? what combination gives best battery life??? also give links if possible...
Well, first of all, there applications that are supposted to increase battery life. For a few examples, you could try Juice Defender(my personal favourite) or Watchdog Task Manager. I personally did try some GB Darkys' rom, and I wouldn't recommend it. The battery life was terrible. I'm now running WeUI, an ICS rom. I also tried CM9, and it had a pretty good battery life, but it's not really what I would recommend you to use as a daily usage rom.
You might also want to check your screen brightness settings, I personally have mine set at "automatic".
Also I'm not that sure if semaphore has a good battery life. I heard that Icy Glitch has better, but I am still running semaphore 1.0.0.
Let me know if those apps make any difference!
Back in the day when i was a darky user, i also tried semaphore and hat good results with it, 2days or more were common. I used BUJV3 modem mostly. But generally I had 2g running. The battery life always drops a lot when you constantly turn 3g on. Btw moving to ics reduced my battery life, I charge every night (sometimes earlyer).
i have juice defender... also i turn off the 3g when not required... and i have set the brightness to minimum.. but still i want to conserve more battery... can any one give me the kernel which uses lowest battery without much performance lag??? any ROM??? any good ICS ROM with good battery???

I was using an app called SuperPower XDA-BETA v0.80, that can be found on market.
As for me it's the best app for customising power usage, a bit tricky, and rot needed for most features, but I was finally able to prolong my battery life to 2,5 days.
i don't think so apps can save much battery as it will switch of the radio services which i am already making off when not required.. i am talking about battery Hacks or Kernel or ROM which will give extra battery power???
]Dude you want to use 3G too and still want battery life of upto 2 days !!! quite a dream...
anyways few things you can try on.. these are not hacks just tips
- remove any widgets on your homescreen
- turn off autosync
- don't use any constantly updating apps like weather, clock widget etc
- turn off auto rotate (read in some thread this as a tip too)
- don't use automatic task managers
- don't use any battery saver, turn off the data manually when not using everytime
- don't use live wallpaper and try to use some dark background image preferably black
- use some black and white theme
- remove/ freeze as many system applications as possible which don't affect your normal functioning and the apps that you don't use

GALAXY Note: Battery life is so less. ?? (Please Help)

Hi everyone. My battery life is really sucks. I bought my item two days ago. It is new. And I upgrade my version and baseband , kernel and build version like below :
N70000XXLB2
2.6.35.7-N7000XXLC1-CL1003701 [email protected]#2
GINGERBREAD.XXLC1
I think that this version xxlc1 is last version but I wonder how is my kernel version ?
Battery life is very bad.
Moreover Charging lasts so long. 3 -4 hours sometimes.
PLEASE Help me! please
depends in the usage, rom, kernel, settings etc you are using.

when i see some kind of usage experiences, I am so jealous. How they use this much ? HOW. I only use wifi and radio.
Hi,
What is your battery life on the Note? Does it last a day even two?. If it does, then that is pretty much normal. You whine on a phone that you just use for only 2 days? Stop whining and complaining. You havent have had utilize the full charge and recharge cycles of your battery and now your whining already.. Man, give your Note a week or two and your battery life will be okay.
Hmm.. Is this the first time you use an android device? What phone where you using.before? If you we're using a non android device e.g. Symbian or etc. Then my reaction to your complains (of your Note) is justifiable. Symbian for the fact has always been known to be very good or decent in terms of battery life.
Now android OS, is known throughout (irregardless what smartphone/tablet you have) to have the AOS bug. It is a bug where there's some sort of a battery leak and hencefort most android users tend to root their phones so that they can stop background stock applications from running in the background. The births of custom ROMS and Kernels have given some tremendous wonders also especially on phone's UI and more so on battery management.
Again. Stop complaining and go down root your phone and install battery saving apps or custom ROMs. It's all over the thread anyway.
The sooner you customise your phone to your heart's content, the better you can appreciate it's full potentials.
Cheers!!!

My battery life is 5 - 6 hours. I am accept 12 hours. I wish it last 12 hours. Before I used Iphone4, it is not so long for battery life , however it is acceptable. I did not understand how notes's battery life so short.
Moreover I can not use custom rom. because they r not good as well as stock rom. ALl of them have some problems. But I can change my kernel.
to get battery life you either
a) dont use your phone or
b) get information to use your phone more wisely
So..
a) download a battery monitor.. there are a bunch recommended..
b) read the other 200 threads on battery life and dont start another one. Each and every question has been asked and answered ad nauseum
while you are figuring out root, and task killers, here are a few easy tips to help..particularly when you are putting the phone down for a while
apps>task manager>active apps> CLOSE ALL
apps>task manager> RAM> CLEAR MEMORY
settings>applications>running services> review and shut down apps/games that may be running in background (and that are not critical)
Again.... RESEARCH the forum.. the answers are already here. and you should read and post in existing threads

You could also have a defective battery.
On my iPhone 4, my first of 4 that were faulty, battery life depleted in less than 12 hours of STANDBY only on wifi, nothing syncing. Only being on. Battery life was so bad.
It's not uncommon to get a dud battery sometimes.
Try doing a complete restore, stock EVERYTHING, don't push anything (except email, cal, and contacts, you know, the basics) and see if you're having the same results. If on a fresh, stock, install you're having the same issues, then you've got a defective unit and/or battery.
Hope I've helped.

There are quite decent custom roms for the Note. I have tried many gingerbread versions (Chracks, rocketrom, cassies etc) currently on chrack's v18 small (LC1) with speedmod latest kernel.
I have not faced performance issues on this. But each user is different so u r the boss.
Best give the custom kernels a try for now. If u find the battery life better then ur problem is solved. The advantage of custom rom is that so much useless bloatware in the stock is removed for better space mgt & performance.
have provided some tips in the following link, feel free to go thru.

dude, you are ridiculing some of the well known devs who have made custom ROMS for all to appreciate and use. IF there was and is a problem on a particular custom ROM, it is or might be cause indirectly on the user itself, on what apps he/she insatalled on his phone. Surely you cannot generalize all custom ROMS have problems do you? if all have problems, the devs have some new revisions to fix those bugs and in no time at all your Note would be in tip-top shape again.
If as what you say, Custom Roms have problems.... then why the heck most people I know have used them and have big wide grin on their face to show off what they have and even posting a copy of their latest ROM pictures here... not to mentioned in YouTube as well.
ok. Which rom is the best stable than ? Which I should use ?
go read the threads on battery performance.. loading a new ROM will not fix problems if you do not know what you are doing.

Hi there.
I had the same issues but only after the update done on ICS.
I have over 140 different application and nearly all of them have been purchased.
What happens is that, when you are not using your phone it should go to "deep sleep". This allows your phone not to run any application and merely use any battery. Your problem probably come from somewhere in your setting an automatic update. That drains a lot....
I downloaded different application hoping that it would work out such as Juice Defender, watch dog and many others. After lots of research, I found out that it is not good for your phone to have an auto killer app or even an application that modifies the functions of other applications.
So I downloaded battery spy and cpu spy on "google play" and followed the instructions.
I needed a deeper analytic application "Kernel" and this was THE application that allowed my phone to go from 6-8 hour to 28 hours.
"Better battery stats", it's not free but was really worth the spending.
Google play chronological download
1) watch dog
2) battery spy
3) cpu spy
4) better battery stats
Good luck
I keep switching my cellphone off while not using, and same goes for wifi. Using it as a secondary phone as well. It lasts only 4-6 hours.. :S I keep closing background apps, and kill app once im done with it..
Also be aware that in areas with bad network strenght, the GNote really suffers.
I normally have no complains (0,6-1,5% battery usage per hour) but where I am now, the GNote really works hard to keep the connection and my consumption easily goes to 4-6% in deep sleep and 15-20% when using it...

If you like stock samsung looks try CleaNote 3.10 , very good n battery life , I get around one day backup with heavy usage and 2 days plus with moderate usage .
If like pure google , then try cm9 , very stable and quite good on battery back up .
And if you dont use 3g or 3.5 g or any such networks then select GSM only or use 2g networks only ( Settings -> under wireless and connectivity , More -> Mobile Networks )
Also keep your display brightness to minimum , control the brightness manually instead of auto brightness .
Turn off auto sync ( big advantage over battery ) .
Scan for running apps and cached apps and force stop the ones which you dont use .
Use titanium back up and freeze some of the bloatwares ( stock samsung apps ) or uninstall them , like readers hub , mydiary , they are **** .
And dont use task killers , they drain your battery . they may clear rom but some apps restart automatically and that needs more juice than running those apps . Hope all these suggestions help . From my experience with this phone

I didnt know that, My signal is usually 10-40%. I have bad signal strenght at home.
my battery decreases 1% in around 5 minutes of use or something. Today it lasted me 10% on standby for around 8-10hours.

You need to purchase and install "better battery stats" and also install cpu spy (I'm assuming you're rooted) and use them to monitor your phone and battery in order to solve your issue. Google both and you'll find several good threads on xda about using and interpreting these apps, but if you get stuck post some screen shots from both and someone here can almost certainly help. There are a number of potential sources of such problems, generally rogue apps, and also a bug or two, but it is impossible to offer help without the details these apps would provide.

Thanks for that, i will install it. By the way i got the "battery widget" installed, which has gained popularity on the market.
Also im only using 9% of brightness of my phone.
I'm using a rooted stock 4.0.3 and I'm finding battery life its pretty good - better than unrooted GB was in fact. Simply freezing bloatware via titanium and limiting sync on some (not all) apps and services makes a gigantic difference. Design your phone around your own needs and you'll end up with an amazing device that you'll fall in love with all over again.

Battery issue with Stock ICS/CM9 ?

So I've been testing CM9 for quite a while now and can't help notice the battery life has been reduced heavily compared to Honeycomb 3.x.
Now, I don't mind that my battery life gets a bit shorter as ICS brings more features and might be more power hungry. But I went from my tab being able to hold a charge in standby mode in 3 weeks to barely 3 days. And if I use it more heavily, it barely holds a day, which is worse than my Motorola Atrix and that's just not normal.
Now, I've been discussing this with pershoot and for him it must coming from something I do. Honestly I don't see what. In the Honeycomb days, I used to have so many apps installed (may 100-150) and battery life was fine. In CM9, I'm running 50 apps, the essential ones. All the apps that could be power hungry have those settings set to off. No push notifications, very large updates intervals (a day) or none when possible. Also, I run most on these apps on my Atrix (which has more apps installed) and my battery life is way better on the Atrix.
In usage itself, I don't see any change, it seems the tab consumes the same amount of battery than before. It's the sleeping battery life that is terrible. In my case, in sleep mode, wifi is off, brightness is set to Auto and data is off (not the signal itself but I tried to take off the SIM and the battery life is the same).
Honestly, not having to care about charging every day is a must feature for a tablet.
I'm running now RS125 ICS, based on stock and the issue is also there. So I wouldn't say it's something related to CM9 but more on how ICS behaves with our tab.
I've read report of other people complaining (with the 10.1 also) so I wonder if it's a general issue. Could you please fill the poll so we can see if there's an issue and if so, how could we identify it ?
Don't hesitate to describe your tab usage and battery life !
Thanks !
For me worsts battery life was with the official 3.0.1. 3.1 was big improvement. 3.2 and 4.x were a little bit better than 3.1.
Got gmail and exchange push notifications turned on, but most of the time the tab is connected to the wi-fi, not to the 3G network
Attached is my personal stand-by record on the 10.1v. I think it was with one of the first pershoot's CM9 roms
Hi Danny,
Same for me. Especially the standby mode I see a battery drain.
By the way, somehow my battery usage is not working since I moved to the official ICS ...
Cheers
No problem @all. Stock 4.0.4 with OC kernel.. Looks like this:
