GB27 Battery - Samsung Epic 4G Touch

It appears most people are reporting good battery with GB27. Is anyone else like me and having issues? Both ET4G in the household are dropping ~7%/hour. It appears to be from Google Maps according to Better Battery Stats. Still playing with it to try to remedy it, curious if anyone else ran into the same issue and has resolved it yet.

Did you try a factory wipe. Many people with nexus had this issue and factory wipe fixed It. If that doesn't work, go into maps and make sure location is all off and not reporting.

Questions go in QA.
How old are the batteries? They normally only last for a year to a year and a half.

Is google now turned on? That used to be a battery drainer for me.
I average 18-24 houra runtime with 2-3 hours of screen time on gb27

Be sure to turn off Location setting in google maps, as these settings if left turned on, are responsible for a major battery drain (50% battery drain in 8 hours if left turned on vs 2% of battery drain if turned off): Launch Google Maps, Settings, Location Settings and uncheck every checkbox that's there such as 'Report from this device', 'Enable locating sharing', 'Enable location history' etc.

The location services was the big culprit, I turned all that off and drain has come down to a more reasonable 3-4%/hr.
Batteries are new. I've considered a wipe but I went through that with ICS and it didn't end up helping.
I'd like to get it down to 2-3%/hr drain at most. I turned off Google Now. Facebook and Beautiful Widgets are the two I see producing the most obvious wakelocks remaining in BBS so I'm going to try getting rid of those next.
Thanks for the tips everyone.

I only leave use wireless networks checked in location services. While sleeping my phone only drops about 1% per hour. I use the samsung weather widget updating hourly and have email set to check every 4 hours during off peak hours. No facebook and dont like beautiful widgets anymore. Too much battery drain.

Greenify and dsbattersaver should help with battery. I hibernated most of my apps including maps and use slumberer with sdbatterysaver.
I manually sync about one a day.

Tips and tricks: improve JB idle battery life.

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.

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

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,

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 %.

Battery drain on JB!

Is anyone else having big battery drain since updating to JB? I used to get 2 full days now i can't get 16 hours my phone is staying awake. I'm stock unrooted using juice defender plus. Thanks in advance.
I don't get as much battery I get about 8-14 hrs with 2-4 screen in time I use to get 10-20 hr with 3-4 hr screen on time. I hope they realise a update to help fix the issue seems like quite a few are having.
Sent from my SPH-L710 using xda app-developers app
Yes. I suspect you're probably having the same problem as me. Ever since upgrading to JellyBean, the battery is horrible. Checked BetterBatteryStats, and it's because of msm_otg, it's constantly hitting the device with kernel wakelocks. If I look at CPU states, my phone has been in 384 MHz for 97% of the time, deep sleep 0% of the time. Since it's not sleeping, the battery is draining much faster.
It has something to do with USB on-the-go, but I can't figure it out.
I am having opposite experience. I am getting incredible(to me) battery life. Fully charge yesterday at 430pm and this morning after a bit of texting and calls, battery is at 80%. Pretty good and should be able to get at minimum 1.5 days usage out of it at current rate.
Also, disable Google Now. That's known to be a huge batt drainer.

Thanks, we'll see how it goes from here.
Did notice my battery was draining more before JB. Once I downloaded JB my battery seemed to drain worse. Finally figured out it was Nova launcher, so switched back to TW and battery is back to normal, with google now on, mainly just get traffic and weather for now.

I apologize for posting in the wrong section. The battery drain continues even after disabling Google Now uninstalling Facebook, pandora and other apps and turning off gps, bluetooth. Andriod OS is staying awake and killing the battery. In data usage delete apps is running in the background at 43 mb? Anyone else?
For me it started with LI3 then into JB.
I noticed Media was at the top of my list when i checked what apps were using battery.
So i ended up disabling the com.sec.android.providers.downloads and so far i think this has helped get my device back to normal battery life..

I don't like any apps that are supposed to save your battery. they usually contribute to battery drain. get better battery stats and see what's causing wakelocks. it's probably location services related to google now. when you don't need it, turn off gps AND location services

I would be more concerned with partial wakelocks first, then kernel wakelocks second
enable restrictions and make sure your wifi isn't when not needed same with your Data. if you don't have 4g, turn on only CDMA data. went from 50% every 4 hours just to 15%

Exact same issue for me. I will try this.
I have had severe battery drain for a few days now. I disabled google now yesterday and that didn't change anything. My phone was constantly warm. Today, I turned airplane mode on and the battery still drained. It got down to 58%. I read somewhere in this forum that the google maps update was causing some battery drain so I uninstalled the update at 58% battery life. Three hours later I had 57% battery life. So, for now I can only assume that it was google maps that was consuming my battery. I will have to try updating maps again to make this a more concrete assumption.

Network Location Locator wakelock...

Battery life on this phone is ridiculously good...don't get me wrong. However, I have noticed that overnight sleep battery life is really no better than when the phone is in use. I installed better battery stats and see where my phone is being awakened literally every 10-20 mins by network location locator. I have seen several threads that are not dedicated to this, but have individual posts that do talk about it. I figured I would dedicate a single thread to this issue and hopefully come up with some type of fix. If I have missed the dedicated thread then I do apologize. I do not have GPS on, I have unchecked all location gathering data within Maps, I have unchecked location services within the Google location settings and I have all Facebook location settings and notifications turned off.
Any ideas on what specifically would help alleviate this wakelock? I didn't screenshot it, but I had my phone unplugged overnight for about 6 hours and this service was used for about 1 hr 45 mins.

Facebook, Google+ or some other social media/location logging app is usually the culprit.

Appreciate it, but as I stated in the initial post...I have unchecked all maps and latitude tracking services. It looks like 1% loss every 2 hours during screen off is just something that I'll have to put up with. I know with other Android phones (Nexus and One X) I would only lose 1-2% overnight (8 hours). Not the end of the world, as this phone still gets me through a full day of heavy heavy use easily...just figured I might find another few hours

Only way to fix it for the time being is to uncheck "Google location services" under "Locations" in "Settings". The service kicks in via WiFi. Switching it off unfortunately means that other apps (other than Maps) can no longer provide location based services. In short, this bug (at leat that is what I believe it is) is the cause that while on WiFi your phone never reached deep sleep... I hope it will be solved as it is a waste of already valuable energy use...

[Q] Short battery life but nothing specific seems to be a big drainer

Hi guys,
Though I have been reading these threads for quite some time now, I just joined so that I can post the issue that I am facing.
I am rooted and using Liquidsmooth v2.4
I am facing a battery issue. Battery life is short. I never survived more than 2 hours of screen time on my device which I know from these forums that is not normal.
The stuff I have tried but didn't help:
Wiped and factory reset on several occasions, both using the settings function and CWM
Flashed various roms (Cyanogen Mod, Carbon, Liquidsmooth, Stock rom)
Unroot to stock and root again
Changed to various more battery friendly CPU governors
Changed battery with a friend who is using the international version (which is using the same battery according to the Samsung website)
I am not in the states now and the local Samsung service centre refused to service it because they don't have the appropriate parts and also due to the difference in software. (I unrooted it and restored to stock before sending in.) They just looked at the model number and refused service; didn't do anything more.
I have attached some screenshots. There are no obvious wakelock issues and no app in particular is draining the battery. 50% power used on screen appears to be normal. The rest of the apps also look like they are behaving themselves, at least power consumption wise. I am not a very heavy user and don't run any games/apps that are huge in resource requirements. Email/facebook/browsing are my main activities.
The current settings on my phone:
Auto brightness
Wifi/bluetooth/GPS all off
Autosync is off by default but will use it sparingly if I need to.
Almost all of my apps have their notifications off and all apps are set to sync manually.
I only have one calender widget on my home screen, no others elsewhere.
CPU Governor is "ondemand", iO scheduler is "row". Min/max freqency: 384/1512 MHz
Juicedefender is enabled with "aggressive" (I know its effectiveness is controversial but on my device, disabling it eats more battery)
Any help is appreciated. "Thanks" will be awarded to all who post!
Thank you!

I see horrendous wakelocking. Install BetterBatteryStats. Charge it up for a bit, reboot the phone, then let it idle for a couple hours. Then post screenshots of everything.
It might be the worst I've ever seen. Good news is it's probably not a hardware issue.
It also looks like half the time you had a poor signal. Data transfer on a poor signal can wat at your battery too.
Always use wifi when available.

thanks folks. I've installed better battery stats and will update shots accordingly at the end of the day or end of the battery cycle(probably won't last a day)
Really appreciate the help.
Here are the shots for today.
I rethinked about the poor reception comment and wondered if any of my radios are malfunctioning or if my radios can work in the frequency bands here in Singapore. I called my local service provider to ask about the frequency bands and.it appears that my device's radios can recieve the GSM bands here although they suspect 3G may be an issue. Nothing concrete but I do hope to find out if that could be a possible reason for my battery drain.
I managed to squeeze past 2 hrs of screen time today by using as much wifi as I possibly can. This improvement in battery life probably means that data reception can really be an issue. It's not unlikely that both my home and workplace suffers from.bad reception but i do have a Q. If poor reception is an.issue, will the battery consumption by cell radio sky rocket?
For some reason the previous battery stats screenshots was only for about 5 hrs. i have refreshed and have uploaded the refreshed screenshots

This is not BetterBatteryStats. We already know your battery life blows. I want to know why, and BBS will tell me. I can't do a thing for you until you show me that. I think there is a free version on the forums, but it's cheap in the Play Store, and worth it. Get Greenify, too. You're going to need it. Greenify will prevent notifications from showing up for greenified apps. If you don't need notifications from Facebook (honestly, who does?), Greenify it. Maps, too. And disable Juice Defender for now, so I can see what is really happening.
Poor cell reception, if not on wifi, causes drain, yes. It seems to only get really bad when the phone can't hold a data connection.
Try turning off GPS. Also under Settings > Backup and Reset, turn off the Back Up My Data option.
Additionally, check the stickies in this forum. Woody has a fantastic Battery Thread that you should read if you haven't already.

Will certainly post up screen shots tomorrow.
PS: My GPS has been offed by default. Will disabling Google backup services help?

Thanks everyone! I sheepishly searched better battery stats on Google play and.simply installed the first that popped up without looking closely. My bad.

It cant hurt your battery life! Theres a number of things you can do for settings. Read woodys thread stickied here as its pretty much all there. One of the big batt drainers can be auto brightness btw.

Once you get a good cycle run with BBS, the screen shots we want to see are Since Unplugged/Process and Since Unplugged/Partial Wakelocks. Those two will help tell what is eating your battery and also what is causing all those wakelocks in your original screen shots.
If you are using Juice Defender, that will contribute to the wakelocks (but doesn't keep your device from entering Deep Sleep, so no worries there). I use it, but I have mine set up custom plus have done some basic build.prop edits regarding the RILs and wifi_supplicant_intervals.
My suspicion is that there is a rogue app that is transmitting data somewhere and that is not letting you sleep. If it is transmitting in a poor reception area then that puts ever more strain of things. You are not the first and wont be the last but Doc, Aero and I can help you figure it out.
Images for today. I've included a few more shots for the items that appear lower in the lists.
I've installed greenify but did not add any apps while collecting these data. Juicedefender is also disabled. My screen time was less than 2 hrs.
I did some of the stuff listed in Woody's informative thread. Deleting the tombstone files, lost&found files etc.
Thanks for everyone's help. Hope to solve this issue soon.
Get Greenify from the play store.
Greenify:
Maps
Facebook
Google Now
Take more pictures with BetterBatteryStats tomorrow.
Looks like Maps is misbehaving. Terrible coding is terrible.
Yup. Looks like you are broadcasting your location all over the place. Do you use Maps? If not close it and Greenify it.
Are you getting notifications from Facebook or have a "Check-in" thing going on?
Google Now>Settings> turn off what you don't use.
Settings>Location> Off.
Edit: Tombstones and Lost.dir files are just memory management and have nothing to do with battery.
Shots for today. Things are a little better but looking at my screen usage, maybe there's still a lot of room for improvement.
I've greenified just about all apps that may run in the background. Facebook, Maps, Google+, Gmail, Chrome, Google Search (I converted it into user app), dropbox, etc. Whatsapp, Viber and Wechat are spared as I needed them to be able to notify incoming messages. Juicedefender is on, with advanced settings - set to sync only once an hour. Maps have been set not to update my location although I didn't go to the extent of denying location access ( I use maps fairly often).
All these are rather aggressive steps and I do see improvement. What else can be done? Other than my messengers, all my notifications are essentially off.
Once again, thank you everyone for your time and effort.
Please stop using Juice Defender. I want to see what your battery life looks like without it now. And it's also responsible for the majority of your wakelocks. And if you could get us some ~4 hour idle BBS stats (during sleepy time), that would be fantastic.

Noted. I'll charge my phone up and take some shots in the morning. Juicedefender will be disabled and hopefully more information will be revealed. Do today's shots show any improvement?

I think you are heading in the right direction (8% deep sleep improvement). For this next test, please disable Juice Defender (don't turn it off through the app, but disable it in the app manager to make sure it can't run). Also, I'm hoping to get a test where the screen isn't on for more than a couple seconds, so I can get an accurate reading on the usage per hour.
I suspect the rest of your issues (bam_dmux_wakelock), are due to a bad cell connection for a good chunk of the time. Connecting to a wifi network will solve that. If you don't have a wifi network, you can turn on airplane mode, or set up some Tasker profiles to help with that.
Out of curiosity, how bright do you have your screen set? Obviously its a big drainer, but it seems like every time your screen is on the batt level plummets.

[Q] Battery Drain Issue

I am trying to troubleshoot my battery drain issue so I have been inserting a fully charged battery into my Note 2 just before bed.
Stock 4.1.2 ROM
Rooted
Night 1
Before bed: 100% battery, airplane mode
Wake up 7.5 hours later: 100% battery life
Night 2
Before bed: 100% battery, WiFi connected, background sync enabled
Wake up 7.6 hours later: 54% battery life
I have Greenify and BetterBatteryStats and still can't figure out what is sucking down the power.
Sync Interval:
Twitter: 4 hour
Facebook: 30 min
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Any help would be appreciated!
I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it
Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following
Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.
NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.
Things I am going trying.
Freeze Samsung Push
Freeze ChatOn
Greenify Facebook
You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:
1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail
etc, etc.
I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?
Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.
I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.
I need to find which apps are using WiFi so heavily.
Go grab greenify from play store

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.
Try backing up all ur data on internal and SD card.. Then do a complete fresh install.

Yes. I have the same experience. When WiFi is on, the battery life is much worse.

Ok Wi-Fi being on won't kill your battery. Maybe you need to set your to, keep Wi-Fi on during sleep= NEVER. That'll help your battey life some what..
