Hey everyone, last weekend I unrooted and wiped my phone, went back to factory settings, rerooted and installed CM6.1 RC2. I've been enjoying it so far (because I hate Sense UI) but I've got a couple of questions that need answered. Hopefully you all can help me.
CM6
1. Is there a setting to turn off always-on mobile data? I cannot find it.
2. For some odd reason, I cannot turn on bluetooth. I've not had a problem with turning on bluetooth with any other rom. In fact, I remember testing bluetooth the night I installed CM6. Is this an issue with the phone or the rom?
3. No matter how much I turn off Auto-Sync, it turns back on. What is doing this?
Battery Life
1. On average, I get around 10-14 hours battery life a day, maybe a little more if I barely use my phone all day. I've heard a lot of people say that an ideal battery drain with the screen off should be 1-2%/hour, but mine will drain from 6% to even 10% in 40-50 minutes (EDIT: Currently 75% battery left, unplugged for 2hrs 30min, done nothing but use the browser for 5 minutes, download something, and install it)! I use systempanel and spareparts to monitor which apps could possibly be doing this, but none look like they're eating up too much of the battery. I check Facebook 4-5 times a day, use the browser, and check Gmail. I don't use Google Talk. My screen brightness is around 30-40% and I have underclocked when the screen is off with setcpu. What is draining my battery so fast? It's a shame that there are so many cool things to do with this phone but I can't do them in fear of my battery dying before the end of the day
Sorry, that last question was long, but I did not want 2 separate posts. Thanks guys, I hope you can help!

1. no. you could however turn data roaming off or use a program to accomplish this such as "tasker"
2. what do you mean you cant turn it on? what does it do when you enable it? use the widget in your notification drop down.
3. turn off background data as well and that should fix your problem.
and as for you other question. 10-14hrs is perfectly normal for battery life on cm6.1. and fyi: its RC1. there is no RC2 for 6.1 as of yet

Ah thanks for correcting my mistake, and answering my questions. My battery life isn't terrible per se, but I guess I was asking more on how I could make it better (and if I had a rogue app/other battery eater), especially because I see people claiming anywhere from 20-40 hours with a few tweaks.
And regarding the bluetooth issue, it just won't turn on. The option grays out for a few seconds like it usually does when it's initializing, and then it doesn't turn on. The notification widget method does not work either.
Also, there's no other way to turn off auto-sync? I just think it would be a hassle having to turn background data back on everytime I want to use the market. I use JuiceDefender, too, could there possibly be a conflict between the app and my phone's settings?
Man i'm with you here, I use CM6.1 too and love it but the first 30 minutes i unplug the phone from charging i'm already at like 90% battery =/

I had the same problem with my Bluetooth recently. When I try to search for devices the phone locks up and I have to pull the battery. Wonder if this is a kernel issue. I am on snap

I couldn't believe it either, he had 3G on all day and everything and we barely get any signal at all in class. On for almost 8hrs with more than 70% left. I was at about 53%
Please help....
I have read many threads about this, but I don't understand any of them. My battery life is horrible, I am only using it for the occasional phone call, texting and checking my email. It's very frustrating because when I need to use it, the battery is dead (or almost dead and I can't use the camera).
I don't understand all the lingo on here about what version "this" and "that" everyone is using. Downloading certain apps to fix this.....
I'm not very techy and just use my phone for basic things.
PLEASE HELP!!!!
Suggestions:
Turn off bluetooth until you need it, then turn off when done.
Turn off GPS until you need it, then turn off when done.
Turn screen brightness to automatic or lowest setting (your preference).
Turn off 4G receiver if you are out of range or just don't have 4G coverage in your area.
Turn off synchronization if you don't care for email, Facebook, Twitter, etc updates. (Not really necessary if your update interval isn't set for short intervals.)
Utilize Wifi as much as possible, if that is an option available to you. BUT turn it off when you know you will be out of range for a good bit of time.
Toggle Airplane mode after each phone reboot. (Stupid bug)
Utilize the TouchWiz program manager (long press on home screen and under Samsung widgets).
Kill the OmaDrmConfigService process via Settings > Applications > Running Services. (This appears again with each phone reboot, unless you find a process killer application in the market.)
If you use Wifi a good bit, it's a good idea to set your Wifi sleep policy to "Never". You can access this via Settings > Wireless & Networks > Wifi Settings: Press menu and select Advanced > Wifi Sleep Policy. Setting to never will not revert back to 3G when you turn off your phone's display as long as wifi is still turned on and within that connected wifi signal range.
If you still get **** battery life, then you can download Spare Parts or BatteryHistory from the market. BatteryHistory is a ripped out piece from Spare Parts, which is really all you need to diagnose your issue.
OR if you don't want to install anything you can key in via the dialer: *#4636*1111# to get to the same menu that both programs above display. (The menu is labeled Battery History.)
From another battery thread that pertains to the two aforementioned programs:

I have no ideawhy but after flashing a few times testing themes on dk28 my battery tanks and my gallery gets slow. The album thumb folder inside there is what fixes the gallery so I usually delete it but I got lazy and deleted my whole folder since it regenerates on boot and my battery came back. Ben deleting it since lol but I flash a lot

Try this:
-Toggle airplane mode every time you reboot. You probably have a "time without signal" of over 50% if you look in settings. Toggling airplane mode resets the radio and so it doesn't keep looking for signal unnecessarily which kills battery
-Gps on doesn't drain battery, only when its being used by an app
-Turn off background data and auto sync. If you don't have facebook/twitter widgets or care about email push notifications then save some power and switch it off.
-Check for apps that aren't letting the phone sleep. Download "spare parts" and it should show you.
-I'm guessing you have the updated Facebook app with chat. I would suggest going offline in chat because it doesn't let the phone sleep and will drain your battery really fast.

My Epic looks pregnant but the battery lasts forever with the extended one
I am getting very poor battery life. Fully charged at 8am and dead by 5:30. Hardly even using it. I have a limited number of apps on, just a subset of those on my Nexus One and no rouge ones at all. Made a few calls, no web, a couple of gtalk posts and that is it.
See attached usage screen charge to dead and charging again!
The phone is useless like this... any ideas????
Are you in a building with poor reception? I noticed this issue when I left data on when my company moved buildings.

Is that solid blue bar from your WiFi being on all the time, or is that your awake bar on 100% of the time from a bad app?
That battery life looks atrocious. Show us the second screen to see the "awake" times.

I keep wifi and bt on all the time, as I did on my old N1. I am in the same place in the day as I was with that and will have same reception, which is not bad.

That's it, like I say a sub-set of those on my N1 and all solid apps.
I normally listen to mp3 on the N1, but have not had time on the Galaxy yet, so it;s getting less use.

Other than that, don't see anything crazy... This battery life is really strange. When your screen is using less power than the 'Android OS' it shows you're really not using the phone much, but the phone is still tanking on battery life.
I'll post those screen shots for today when I get home tonight.
A few things I have noticed though. It seems to level off at midday, this is when i leave work and go home for an hour. While at home I will be on wifi. I do not connect to wifi at work.
Secondly, while at work I notice my data often changes between "3G" and "H", while the phone is in the same place. Probably 60% H and 40% "3G". It is not practical to turn "2G" only on, as I get the volume bug and the phone becomes unusable.
I am wondering if the data signal is draining it somehow? If so, how can I work around that? Like I said, I have a N1 before the GN which sat in the same place on my desk every day and had no battery drain issue at all.
I unplugged mine yesterday at 7.30am and it died at 9pm
I used the internet on/of all day made a couple of calls and about 50 texts, screen on time was about 4 hours.
Today i've used it in a similar manner and as of now (3pm uk) 7 and a half hours in its on 57%
The battery in this thing is better than my desire, granted, not much in it but it will easily get a normal user from one sleep to another

I'd say with 95% certainty it's just signal-hunting causing the drain. With my Fascinate at work, I'll easily lose 50% battery within a couple of hours, even if I'm not using it, while at home it'll last me between 15-20 hours before getting low. Easiest solution is to just buy another charger for work, and leave your phone plugged in whenever it's on your desk.
Don't like seeing android os at the top of that list! Does the nexus share some of the problems that have plagued the galaxy s line of phones, the android os bug!? :O

I kind of think you might be right. However, a phone that drains itself while doing absolutely nothing useful at all, is no use to me. I carry it about and am in and out the office though out the day. It would be unworkable to keep putting it on charge every time I come back in the room. I need a phone I can carry around for a working day without charging. My old N1 did. If this can't do it I'll need to get short of it and get something more practical. Seems ridiculous though.
Btw, task killer just got installed by default when I upgraded. All the apps that were on the N1 were installed when I signed in. Just never deleted it
Do you leave your Wifi on all the time even if you don't have Wifi signal available? Don't do that.
If you are too lazy to manage your data connection manually all the time, I highly suggest getting the app Juice Defender from the market. You can save the battery by setting a schedule for data connection and also it will disable your wifi automatically if your phone can't find a wifi spot it can connect to.

Yes, I leave wifi and bt on. I want to be able to do this. I am not asking for it to run for days. 1 full day is all, I have not issue charging every night.
I could look at the juice monitor, however, it does not seem too much to ask to be able to get 1 full day from it of average use. To me, it seems perfectly reasonable to expect the device to work for a full day with all services running.
Is there any tool than can be used to prove that the signal hunting is eating the power? Currently is seem to be in the big pot called "Android OS"??
Well, I'm not gonna defend the phone. Leaving all radio processes on, especially when there is no signal available, is well known to drain a lot of battery since the phone uses more power to search for available networks than when it has a stable connection to one. If you leave it on in a place with spotty or no signal it will make the problem worse.
Juice Defender (the basic one anyway) is free and pretty much manages the connections for you and basically extends your battery life with minimal effort. Give it a go for a couple if days.

I strongly agree with chrono.

+1 with Chrono.... Turn off Wifi completely if you are not using it.
if you are a new android user, you should also check the settings of the phone:
hit *#*#4636#*#* in the dialpad.
this will bring up a menu. there you should try phone (i think, my n1 got stolen a while ago). there, you scroll down and there is a menu to adjust the preferred network mode.
if it's set to CDMA preferred, it will search for a cdma single. you just adjust it (i think) to gsm only. google will help you a bit here.
I have done pretty extensive testing in the last few days and this is what I found.
TOUCHWIZZ USERS ONLY, uninstall and delete data for the app my uploads. It syncs your gallery with picasa and uses a load ofdata and battery. It won't break anything. turn off instant upload in Google+. Turn off smart stay and motion actions. they use about every sensor in your phone. Turn off the wake up phrase in s-voice. If its on it is always listening for that phrase. I'll keep looking for other things but I got fairly good battery life just doing those things right there.
When uninstalling an app, wipe cache and data first. This will clear any background processes that could stay after the app is gone.
Install es task manager and kill everything you don't need to run on startup to preserve boot time/battery usage. Also it will keep the processors a lot lower.
All accelerometer and other hardware functions use a significant portion of your battery. If you don't use landscape mode turn auto rotate off because it uses that precious battery life.
Weather bar in notification drop down and on your lockscreen will destroy your battery life. Weather widgets also use quite a bit of battery.
Facebook app also kills your battery because its always connected to the internet. Syncing Facebook account to your phone further wears down your battery. Any game or other app that connects to facebook will also do the same.
Look in data usage under settings. Anything on that list uses more battery because its connected to the internet.
If your not in an lte area turn lte mode off because your device will be searching for a signal it will never get.
Low signal strength kills your battery because your phone has to use more energy to hold connection to the network. If you have WiFi at home and bad cell service (or anywhere) use WiFi because its easier it is for your phone to hold good wifi signal than bad cell signal. also turn off your NFC. It uses more battery than Bluetooth does.
Get better battery stats app and look for wake locks because without deep sleep you will never get more than 12 hours battery life.
Widgets, live wallpapers, lock screen ripples and other things that move use battery also. If you don't use it then remove it to save a couple percent a day.
Remember that when charging through a computer USB port or things like that charge a lot slower than an outlet. Slow charging is better than fast charging because your battery stays cooler and that means your batteries total life will be longer.
Finally before you go in a ROM thread and start complaining about battery life, go at least three charge cycles after flashing to optimize your battery.
There are many things that cause battery drain so beware when you download that next app. It could be a battery sucker. If you don't need or don't use an app. Uninstall it because it may have background processes that are using up battery and RAM.

You can uninstall the facebook app, go to facebook on your browser, create a bookmark, and then place a widget on your homescreen for that bookmark. The site is actually faster than the app.
In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

Anyone know how to fix 1013 wakelock. Tried scanning and repairing damaged mp3s and converted my m4a files, but still have quite a bit of drain. Any help would be appreciated.

ii.Mediaserver. This system process is tricky when it comes to battery. What happens is that whenever you access any sort of media on your external SD card (playing music, gallery, what have you), this process kicks off. Luckily though (but hard to catch), sometimes, this process uses more process time than it should due to corrupted contents on your external SD card. In order to catch this culprit: try clearing your battery stats (for example, restarting your device or coming off AC power), playing some music and/or checking out pictures on your SD card for a few hours. Then, check your processes. If Mediaserver is high up there in usage, you may want to consider cleaning up your SD card. Naturally, we would expect that the process is higher when media contents are in use. I can’t give you a specific guideline such as, "something is up if Mediaserver consumes over 25% battery." This is another example of where you should look up other user stats for system processes based on your specific phone and OS version. If you think your SD card may be corrupted, backup your data, format the device, and slowly, add back files and repeating your media tests. Finding a corrupted file isn’t a guarantee, but this doesn’t hurt if you suspect data corruption.[/QUOTE]

Turn off GPS when not in need. Turn off WiFi when not near wifi. All the stuff in the op. And undervolted by 100+ mv on every CPU setting. And my phone is absolutely lag free accept when I hit the unlock button it takes like half a second for the screen to come on instead of instantly (160mv undervolted on 192 which is sleep speed I set)

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

Maps is known for that. If you don't mind my asking what do you use maps for and could you just use Google now to search locations and it will even give you traffic n stuff. That would probably get you another hour or so a day.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.
Thanks for the tip

It looks exactly the same lol. Just one was running on battery longer than the other?

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.
I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.
Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings

I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.
Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

Also even though you are disabling sone of these apps like google now.... you can still use it your just turning off the background nonsense

what rom and kernel are u using
Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that
I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.
Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.
(To save time, I'm cutting & pasting my post from another similar thread.)

"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,
El Mono
I noticed the huge difference as well. I was walking around Chicago yesterday and not using my phone. After 4 hours I looked and my battery was at 50 %.
