Bad battery life after 107 update

Just like the title says. I have checked all my settins syncs which programs are running in the background and so forth.. so im sure its not that..
Anyways here goes.
Before the update I could get about 12-14 hrs of use out of a full battery charge, however after this update I can only get about 5-7 hrs out of a charge.. Nothing had changed.. my usage is the same, my wifi,bluetooth,gps,4g are all off. I don't have any programs syncing or updating in the background.. So i have NO CLUE as to why my battery life cut in half after this update.

I already posted this elsewhere......my battery life was really great before this update.
Same exact settings now as before, plus the phone was reloaded to factory settings by the Sprint store first as I was having some other issues...email not coming through timely, cell signal falling and dropping calls, etc.
My battery life is now 1/2 of what it was prior to the D107 update.

I would say wait and see. When I would flash roms on my HTC phone the battery would die quickly for awhile. After 2-3 full charges it would go back to normal.

Check Cell Standby in battery status. See if Time without signal is 50% or more.

Cell standby is 18% and time without signal is 7%

My time without signal is only 2% So I'm not sure what is going on to make my battery life soo bad.

i got 9 hours today with decent usage where before if say 12 or so ... since the update my time without signal is in the 30-50% range on average & it was 3-4% before .. im a little frustrated on that & i know its taxin the battery a little so . . .

my update has really screwed my battery life. I notice too that Juice Defender keeps reading at 1.00x instead of 1.6-1.8 before the update. I also notice my TWS was at 50-52%. I tried the Airplane mode toggle and it didn't do ****. I really love this phone, but i'm about to return it and try another before my 30 days is up.
So far, i'm concerned with:
back button is not consistent (works sometimes sometimes it sucks)
TWS over 50% of battery consumption.
upgrade made juicedefender not work
little wobble in the phone but not too bad
scratched screen just from rivet in jeans
AND pissed about the tv out that sprint omitted

The back button is a defect in an early batch of phones.. If you swap it, you will probably get a working model..
My email app didn't sync after the update, so I had to reinstall Roadsync. It might be the same thing with JuiceDefender.

My battery is getting much better. Not sure if it is the galaxy rom, the update or my battery is just getting conditioned better. I unplugged my phone this morning and have been on it constantly web browsing, music, 4g, 3g, lots of tapatalk use. 36% left and just approaching 4hrs of being unplugged.

How do you roll back this update.
Sent from my Samsung Epic 4g using XDA App

after i re-flashed and updated, ive experienced big drops from the 90% zone to like 75% in a short amount of time but then the decrease stays pretty slow.
im using adv task killer on maximum and juice defender
this combo works pretty well for me, i cant explain the 25% loss. I think my battery still needs calibration, but i get around 14-18 hours normally.

I've noticed the increased battery drain also. I've been tracking it the past couple days with Spare Parts. If you open Spare Parts, click on Battery history. If your phone is running like mine is right now, the Running time is at almost 100%. That means that something is preventing it from sleeping. Next, click the tab that says "other usage", and change it to "Partial wake usage". Mine is showing that Android System is the culprit, causing the partial wake lock. It was not doing this before the DI07 update. I did a factory reset this morning and the only app I installed was Spare Parts, just to make sure it wasn't an app I was using. I get the same results on a fresh clean ROM as I do using noobnl's ROM. NOT COOL!

Well my full run through of the battery is over. I've turned a new leaf about the battery on this. I'm keeping the Epic.
Conditions: Was at zero brightness for about 4hrs of this. Set it to 0 after getting to work. You can see the screen perfectly fine at 0 indoors. (30 minute ride)
GPS - Off except the couple times I checked out google earth
Sync - full manual syncing / with background data on to use the market
Usage: Heavy heavy usage for all but 20 minutes. Total time with screen actually on was about 4 1/2 hours. Lots of tapatalk use, streamed about 20 minutes of CNN via Slingplayer, Streamed about 10 minutes worth of music via last FM. Dolphin browser usage. About an hour of total usage was over 4G
No task managers (well Androids but that doesn't count), no juice defender.

After all that it has been sitting at 3% for 20 minutes (after taking the ss) with no usage as I wait for it to finally die and write this post. Just over 5hrs straight of near pure 3g/4g data usage over various applications and multimedia is perfectly acceptable to me. This is WAY longer than the average consumer laptop would get under similar usage w/ an aircard.
If I didn't use the phone like a miniature laptop so heavily and just kept it to normal use and some phone calls with auto brightness on I'd guesstimate I'd easily get 10 hours or so if not a lot longer out of it.
Running: Andromeda Galaxy Rom 1.0.3

the reason your getting bad battery life is because it reset all your battery stats. it's going to take a couple days til your battery life gets better. try the bump charging method.

Crazy Android OS CPU usage

I am getting crazy CPU usage from Android OS, which is currently sitting at 52% battery usage. The CPU time of Android OS is between 20 and 30 minutes per hour! I have tried freezing many apps, I have tried task killers, rebooting etc. I have WKE7 firmware.

android os does use more than the rest, unsure why, but somehow the battery ife is still pretty good
http://goo.gl/cyd1T
KE7 (stock kernel) , full sync on google stuff + 1 email on push + auto brightness + about 1H of display on time on this, 1d20min and 68% left.
sent 3-4 sms and did a bit of various stuff since yesterday.
Seen worse lol

I would be very happy with that kind of batterylife. Sadly, my phone loses about 35% battery while I'm sleeping. With medium usage, I would usually reach 12 hours of battery.

i rate my battery life to smth like "amazing" xD

Yes for me battery life on sgs2 is also very nice - I'm comparing to sgs and it is about 20% better. My heavy usage today was 5 hours of screen on with wifi, some gps, 2h of gaming, skype running for about 3h, and battery run for total 9h. Also I use 2 push email accounts and sync is on. I think thats really good. And typically when I sleep in 8h battery is drained for about 8% with all email and google syncs active. So this is also quite good. All that on KE7. Most of samsung bloatware frozen.

Been trying to keep away from these battery threads, but noticed today that I've gone from android system 12% to 30% and I've no idea why.
Still on KE2, and am probably a "light user" - black wallpaper, brightness 20%, screen timeout 2 minutes, some phonecalls, lots of SMS, music - lots of Poweramp - shown a few photos, occasional wifi, GPS ca. 30 minutes per day, don't sync, don't use my carrier's dataplan, no e-mail as yet, and no Facebook/Twitter/games/Social hub/accuweather etc ever - in fact they were uninstalled on day 1.
Got 36 hours from my last charge, am now on 79% after 16 hours. Still happy with it, but no idea what has caused this spike.... Will keep an eye on it.
My $0.02 worth.

I am really starting to wonder why some people have amazing batterylife, while others are having terrible battery life. I would be very happy with 18 hours with 4 hours of screen usage, but instead I am barely scratching 12, today has been even worse. 10 hours with 3 hours screen usage...

So far mine is 2hr 15 mins screen on time, mostly browsing on 3G, 13 hours on battery, and have 29% remaining. Its OK, but I wouldn't describe it as amazing. Roll on 2.3.4

the thing is on android battery life largely depend on apps and setup anyway

Yeh, I know. But I feel like I have optimized my setup as much as I can. No autosynching, email check every 2 hours, facebook, twitter and RSS updates ever 4 hours. No GPS, automatic screen brightness, wifi sleep on. No widgets pulling real time info.

mine has the stock weather widget and animated background - also wifi always on (that prolly actually helps ..)
also i used some gps,played short videos, youtube, recorded some vids and took a few pics (you can see i used it more heavily today in the graph)
im supposing a lot of this goes as android system (bug?) cuz its certainly intensive and isnt in the list (not even lower)

Get rid of the auto screen brightness. I find brightness of 10% makes a huge difference. This samsung screen might look great but in fact it's practically useless as it drinks power

with ke7 as u can see auto brightness doesn't seem an issue for me anymore
i like it because i don't need to set the brightness in sunlight when it's auto hehe

What is your CPU time on Android OS vs. total battery time? Right now my phone has been on for 2 hours and 14 minutes, and CPU time in Android OS is 43 minutes!

If you've read through the majority of these threads, what's weird is that some of you that have uninstalled and/or frozen specific apps are getting worse battery times than those of us that are bone stock and have everything whirring in the background. As an example I use Wi-Fi a lot and also Kies Air and connect to a Blu-ray player using Wi-Fi Direct. The Wi-Fi Sharing app never appears in my running apps after I turn Wi-Fi off. Yet some of you with tweaks that don't use Wi-Fi have it randomly appearing and eating up CPU time.
I've kept up with this thread and other battery threads and for every "ah-ha!" moment there's a post following it showing worsening or no improvement. Somewhere in one of the three battery threads there were some tweets from Google acknowledging the problem in running 2.3.3. with dual-core processors. I think other than for the mad scientist fun factor we're just beating a dead horse and 2.3.4. is going to have to be our salvation. There's not even any assurance that a cooked ROM sans all the Samsung tweaks would work any better if the issue really is a core-OS problem.
Back to our ongoing debate...

[Q] Newly rooted NC having battery issues...

Got a NC for xmas and rooted it and installed cm7.1 and everything seems to be working well except the battery. I went under battery use and i see that Display is eating about 60% of my battery! I turned brightness down to 25%-ish and i have also turned off everything i am not using but the problem still persists. I have seen people saying i need to do some kind of battery calibration but i do not know how to do this. If someone can help me get this issue resolved it would be greatly appreciated.

Unfortunately, you can only do so much about screen battery consumption. Turn brightness down as far as is comfortable, but personally, I don't want to give up the vibrant display. I find 25% is usually adequate indoors. With my screen ON, it consumes roughly 10% per hour of use, which equates to 8-10 hours of use -- not bad. With the screen OFF, it sips less than 1% per hour, and often less than that over a few hours.
Keep in mind, you WANT screen battery consumption to be the largest value. That means it's nice and idle when you're not using it. If something else is using a significant amount of battery, that may be something you can do something about.
As to calibration, I do find that Android battery gauges often are incorrect until you let the battery completely discharge from a full charge once. Then it's calibrated correctly. Of course, that's not recommended for battery health, so don't do it compulsively. I had a device that showed 1% battery remaining for 3 hours while I played MP3 audio.

I wish i was getting 10% an hour, im getting roughly 20% I now have another issue that i did not have this morning, i can not connect to my computer via USB. Is there a setting i might have turned off in my fit to increase battery life?

@Lsjreadingpa Renaming /system/app/phone.apk to phone.bak is a commonly undertaken act that can significantly lower battery usage. Also, you can turn off Account Sync when not using it actively, as it increases battery drain when you are not actively using the NC.
As far as the USB is concerned, make sure you have USB debugging checked in the settings menu.

How do i rename it? Also a bit of an update, i have turned off syncing as well as alot of the other options and i am losing 5%/20min

Last night I cleared cache and battery stats and let the battery die and then charged it to full this morning. Like I said above I turned off syncing and gps as well as removing beautiful Widgets. I just don't know what else to do. I'm attatching two screenshots showing my battery use in the last hour.

You can use Spare Parts to check what's consuming battery if your DOMAIN supports it.

Anyone able to help?

Are you concerned about battery consumption while you're using it? If so, then your brightness and the applications you're running are going to determine your battery life.
If it's battery consumption while idle (screen off) that you're concerned about, then do you have any widgets that do network access? I found that my battery life dramatically improved when I was no longer using the Twitter widget.
In Spare Parts you can go to Battery History, then check 'Partial Wake Usage'... this can help you figure out if there's an application that's preventing the device from going to sleep.

I would recommend trying a newer nightly or the Mirage/Kang build found in the Android Dev sub-forum here. I forget when they were added, but there were a few big improvements to CM7 a while ago to help with battery life.

Battery consumption while using it is kinda of scary because it drops like a brick. While sleeping, which i don't think it was doing, seemed to get better after i removed beautiful widgets. How different is the Kang build?

The Kang build has an updated kernel and other updates since the last CM7 nightly. It's supposed to fix an SOD issue. I've been running it for a while and am very happy with the battery life.
Like others have said, battery life while using it would most likely be helped by adjusting the display brightness, kernel settings and/or stopping "rogue" apps. You can see the kernel settings by going into the Settings Menu, then Cyanogenmod Settings then Performance. I use the InteractiveX governor (I believe "Performance" is the one that keeps the CPU ramped up constantly) with the highest overclock.

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.

Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though

If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.

Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%

Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time

A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.

Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.

An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.

I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.

Battery Life Help! BatteryStats LogCat Help Please!

Guys, I am getting terrible battery life on the newest BajaRom. I was getting decent battery life but somehow everything changed. I want to note that I cannot access the Media Battery Drain Fix in the BajaROM settings as it crashes EVERYTIME i open it. I have tried everything to install something that will fix media battery drain but I am unsure if this is what is really causing my battery drain. Please any help would greatly be appreciated!

Wakelock Detector and Greenify... are ur best friends on the Note 3.
Turnoff wifi,bluetooth,gps,etc when not in use. Set CPU to on demand. I always have power saver on unless I want to run a game... doesn't seem to effect anything else.
There are a ton of tips for Note 3 battery life...just search here...
I also use LUX for screen brightness, that made a big difference also. Change you wallpapers to darker colors... mine are some sort of black background...
I can make through the day with reasonable usage on Hyperdrive RLS8 and still have battery left...
Haven't tried BajaROM yet...

Thank you for your response. I have greenify'd most of my daily apps and I use wake lock detector and still cant find out the culprit here. It says that my SCREEN is taking up 30% of my battery life after just 2 hours unplugged and minimal use and I'm down to 82%. Can my phone just be inherently defective????
This DOESNT feel right. I NEVER had any complaints of battery with my NOTE 2

Check your data usage. I had the similar situation, saw nothing in the battery usage area....but then checked data usage. I had over 2 Gigs of data usage from EMAIL in only 2 weeks! I had been using the std email app...and get maybe 10 emails a day. Obviously something goofy going on in the sync. Yet battery usage showed next to nothing for the sync process or email app.
I removed my accounts from the email package, froze the email package and installed AquaMail and my battery usage cut by at least half....my data use flatlined.
Obviously it takes power to use the radio for a Gig a week of data....but that does NOT seem to show in battery usage.
so check your data usage...see if email is way out in front. That may be your problem.

I had the same issue with battery life after I flashed to and of the KK roms. My problem was Greenify, and I don't know why. Removing it didn't solve my problem so I'd restart from the beginning. My drain is less than 1% per hour idle without it and almost 10% per hour running all the same apps with greenify in different settings. Jasmine ROM just drained for me all the time.
*first post, be nice. I only joined because of all the trouble I went through to get my battery life back.
