[TIP] Increase battery life on JB 4.1.2

Hey guys
We all have been facing a lot of problems regarding Battery life in JB 4.1.2(Updates with the same changelist )
Here's an app i found which provides a great walkaround from the battery drain but with certain restrictions in device performance - DEEP SLEEP BATTERY SAVER
I used this app when im travelling when syncing emails and stuff doesnt really matter or i can do with a 30 min or so sync interval
Here's the link for the original thread on xda
http://forum.xda-developers.com/showthread.php?t=2030696
How Deep sleep Battery Saver works
Deepsleep battery saver constantly puts the device to deepsleep mode while screen off. During deepsleep mode, Wifi, 3G are turned off, background apps are stopped. Therefore, most apps are not working, including Facebook, Google Service, etc,. It then constantly wakes up in order to download email, sync Facebook status, etc, which is defined by deepsleep frequency and woke up duration
By constantly put device into deepsleep mode, we will save battery life due to no Internet connection, and therefore most of network-based apps, such as Facebook, Gmail will not work.
Caution: during deepsleep mode on, this app may disrupt your normal activities, such as your email notification comes with larger delay.
In advanced mode, you can customize more parameters, including day/night settings, active period, screen timeout, sync strategy, ignored apps, etc,.
Thank me if i helped

Cool thanks! But I'd rather charge my phone in the middle of the day (which I don't have to do even with the battery drain that 4.1.2 brought) than have it turning off radios and not getting calls, messages and notifications. If you disable those, then what's the point of having a totally awesome specked out Note 2! But to each his own ^.^

It does not turn off the radio. Have you even read the thread ? jeezz....stop assuming...

It doesn't turn off the radio, it just delays the sync internal for email, the rest of the functions remain the same

You call that increased battery life?

Yeah that is increased battery life with proper usage, sync was on all the time and i used wifi whenever available with intense screen usage not just low light reading, brightness was around 50-75%
Sent from my GT-N7100 using xda app-developers app

Deep Sleep was/is not a problem on 4.1.2, rather it's the excessive drainage when you are actually using the device, that is lesser screen on time than 4.1.1. Deep Sleep works pretty fine on both ROMs.
'Swyped' from my GT-N7100

It's nice if you think you see a difference, but I think you would have the same effect with juice defender or even tasker with a sync and connectivity schedule. Our device has a much more effective deep sleep than older phones already, so I think it's only the sync schedule that's making an impact.
Unless the app prevents wakelocks for some reason, though that wouldn't really make the phone very stable.

TIP Increase battery life on JB 4.1.2
You could down the CPU to 1.4 MHz clocks, it is worth 3 hours extra endurance.

I'm beginning to think that wifi is the big drainer. On previous version and previous phones, I would leave wifi on all the time. On 4.1.2 though, I'm finding that 3G is less of a drain with screen off that wifi is.
Which is a bit strange to be honest..

Wifi does seem to be draining a lot of battery life in 4.1.2 as compared to 4.1.1
But there is another thing i noticed, the screen brightness at the lowest setting has dramatically increased from what it was in 4.1.1, i remember a guy checked the max brightness and found it to be around 300% of 4.1.1

Many apps prevent the device going into proper deep sleep and cause partial wakelocks or so, I've tried other apps too like battery saver pro and juice defender but i found this one to be the best

Hey mate
Try an app called screen filter. I use it every night in dark conditions.

I find that my phone "wakes up" much less often on 3G rather than wifi.
This is surely a bug and I hope Samsung sort it out. This is my first Samsung device after 5 HTC phones stretching back to the WinMo days and 1 iPhone. The uglyness of Touchwiz in comparision to Sense, and the idiotic choice to use the internal storage as a "fake" SDcard are frustrating to say the least. But this uneccessary battery drain on 4.1.2 is a constant pain in the ass and needs to be sorted ASAP.

I'm already using Screen filter
I meant the screen brightness issue might be draining the battery to a larger extent than what we expect it to and yeah i hope samsung comes with a stable release of 4.1.2 soon or even better 4.2

I actually doubt that
I've used all the latest 4.1.2 roms - DMA5 , DMA6 , DMB2 etc.
None of them seem to work well in terms of battery life ,4.1.1 actually worked like a charm :laugh:

Battery Life is absolutely horrible

Ive been using an iphone 5 and Optimus G Pro for the past 8 months waiting for the new androids to come out this fall and I am quite disappointed. I have the ATT version, i have wifi, gps, bluetooth all off, never had to do that on the iphone. I close out all the apps and clear the ram, and I went through 30% overnight while I was sleeping. My Optimus G Pro was far better on battery and that seems kinda backwards?
Is there like a break in period or something, what is the deal here

You have to figure out what application is causing the "wake lock"
What a wake lock is; Its something running in the background that is not letting the phone "sleep" or otherwise go idle. Meaning your phone is running full speed ahead while you are sleeping.
It could be all sorts of things causing a wake-lock. I had one guy on my ROM have a wakelock because his internet connection was so poor the phone just kept searching and he was draining about what you are draining everynight.
Another thing I would look at are your location settings, not just GPS. The new Google settings Icon has a bunch of crap that it syncs and tracks you via all sorts of stuff. Go in there and make sure nothing is turned on you dont need...
And lastly, like the other guy said, check for a battery stat app. They can show you what app is not sleeping or why your phone is not sleeping like it should.

Facebook is a notorious offender. With refresh off I would get over 140 wakelocks in a 7 hour period.

I was experiencing terrible battery as well. I disabled the haptic feedback with the keyboard and also google now. My battery life seems to be pretty well now. Also disabled leaving wifi on while sleep and off charger.

The battery is awesome on mine, way better than the S4 and Note 2. I'm at 100% still and it's been off the charger for 2.5 hours, where my S4 is at 91%.

mine is way better now, after being off the charger for 3 hours I'm at 94% where as yesterday I was probably at like 70% at this point.

Don't forget most android handsets need a 72 hour battery calibration window before you will see a more even battery level. After 72 hours your phone should have a good batch of data to help gauge its power levels.

Battery is fantastic on this phone. Coming from an X and Note 2.

I'm still on my 2nd full charge but notice once the phone huta around 60% the percentage drop starts to slow down, I figure this is just calibration getting dialed in and so far I'm very happy with battery life.

fd toggle
Hi there, I am not sure if this is the reason but I used to have Fast dormancy toggle apk on my old lgog to prevent the phone from complete discharge even though I was not actively using the devicd. I installed the fd toggle here,too and I can honestly say that if I am charged 100 % at about midnight, I have the same 100 at about 6:30 when I get up. Of course, no data,no sync,no wifi and no active use of any kind during that time. I do not know if the app is the key but the result is pretty impressive. I have the korean version F320K.

I was using the Snapdragon Battery app on my DNA. Never sure if it did anything. Is it worth using on the G2 as well? Love the phone! Less gimmicky than the S4 and more interesting than the Maxx.

This is dumb. My G2 was at 100% battery for 3 hours! You either have a lemon or your cell reception is poor where you are. The battery life is not horrible.

Yeah, I'm with the rest. I'm coming from a MAXX HD (insane battery) and the battery optimization on the G2 is far superior (albeit smaller battery).

Bought the phone over 24 hours ago and I am still on the charge from the box. Its running great for me with LTE on.

Annoying "Prevention Information" Message and Samsung watch on drains battery life

Annoying "Prevention Information" Message and Samsung watch on drains battery life
Unlike others, I only get the prevention Knox message when I turn on my wifi radio. Any reason for that? Do I have to root in order to get rid of this damn message? Thumbnail attached.
Problem number 2. I was really loving the Samsung watch on, because I actually take full advantage of the IR blaster built into the phone, and I found the universal remote feature pretty damn useful. One day, however, a day in which I had no used that app at all, I noticed my phone burned about 60% of the battery in about 2 hours. I looked under battery manager and it attributed over 50% of battery waste to "Samsung Watch On". I thought it must have been my fault somehow, closed the app and put my phone to charge. I had to let my phone cool though, because it got pretty hot during the battery wasting process.
The following day, I got woke up at 7 45 am with 100% full charge to go to work. By the time it was 9 am, I was already and 78%, and I had not used my phone at all. Once again, my phone was really hot. And again, over 60% of the battery waste was attributed to "Samsung Watch On". The app cannot be uninstalled (I am not rooted) so I had to "disable" it. Ever since I did so, the problem went away, but I lost a very cool feature of my phone. Anybody has any idea what is happening?
Thanks in advance.

People started getting the message about ten days ago. Here's a 10 page thread from the AT&T forum.

AT&T rolled out an update yesterday. I got the below without doing anything on my part soon after the update was applied. I haven't gotten the prevention message since.
I use WatchOn and haven't had any battery drain issues. Re-start the app but don't enable some of its features like "show on lock screen" and "show in notification panel." Also don't set up some of the social features but do link it to your Samsung account. That's how mine is set up on my N3 and 10.1-14 and its been fine.

I had similar battery drain issues so I downloaded an IR remote to use the IR feature for my upstairs tv. I have google tv so I dont need the extra watchon features. They are nice, but an app that has to be always on...no thank you.
As for the security thing. I disabled for 30 days so I dont get the message either until I root and get rid of the damn knox...

Which IR blaster did you download? I tried 3 different ones and none worked. Also, I should note, I used the Samsung watch on for a whole month just fine. Without me changing any of the settings, it was after the last update when it started doing weird stuff

Root and get rid of knox app.
Regarding watchon. I didnt see any battery drain at all. I am using 2 ir blaster apps. No battery drain.

I liked the watchon remote but I do not like any app that does not allow me to exit it. I just use the free version of this ir blaster to control my bedroom samsung tv for on/off and volume. The downstairs tv has the logitech revue so it is all controlled through google tv and I have the recommendations, the tv guide and all the stuff watchon offers through google tv (it was just nice to have it on the phone) and my google tv is streamed through a wireless hdmi actiontec receiver to the upstairs tv but I cant control the upstairs tv with the same remote which is why i liked the ir blaster on my phone.

I found the prevention message was actually generated by the stock Anti Virus the phone shipped with. I removed it and put in my own such as Avast and I have never seen the message again.

Yes the ATT branded 900A has Lookout Security preinstalled. It was generating a prevention method about some software making an unsafe operation, but the software in question was some of Samsungs and ATT's own apps. I removed Lookout and instakked Avast and I have seen no more such messages.

I'm just getting this WatchOn battery drain too. However, I don't notice a difference in battery life but I do see it using more power than the screen. It's possible that it's just a bug for the watchon app, considering it's only happened to me recently.

[Q] Battery Drain by "Android System"!! please help!!!

At first "Android System" was like 25% which was okay i guess, I still felt like the battery is not so good.... it drained fast...
But today with moderate use I got from 100% at 7:00 to 5% at 17:30! (and I charged for like 10 minutes with a 1A charger which didn't help a lot)
when I checked the battery stats, "android system" was 43%!!!!
Even when im not using the device I see that the battery goes down very fast! even though I clean the apps in the background a lot!
Maybe i turend on some setting that really drains the battery?
What can I do to fix this?
I have to mention that these stats are with power saving mode turned on!
This is such a disappointment... I hope it can be fixed cuz I expected a lot more from the phone's battery..
Also - I dont know if it helps, but the devices tends to get hot even when not using it...
and the screen is almost always on very low brightness
Attached are screen shots with the detais about "android system"

Check out my thread dude I have the same problem except nowhere near as bad as urs. I thought 20%-25% was a lot but damn 40%+ is insane. I think it's a kitkat problem or something.
A factory reset may help you though.

un-sync your samsung account and uninstall the samsung app store. YMMV, worked for me. :good:

I had this problem, too. Are you using Google+ to backup your photos? Turning off auto-backup made a massive difference for me. I've also switched off Google Now and location reporting, and both made a big different. By Galaxy S5 was burning through battery life before, but it's been pretty impressive since I made those changes. And I still have Samsung Apps activated and my Samsung account in sync.

how do you uninstall samsung app store?

i dont think u can uninstall unless u rooted, but u can turn it off,.

umm AVG is chewing up all your battery dude.
uninstall that junk and find a AV thats light on battery. i use Dr.Web light which has always done be well and uses next to no battery
do you have "restrict background data" ticked on power saving?
and yeah make sure GPS, Bluetooth is off too, only use when needed.
my battery on my s5 lasts 2 days of fairly heavy use

turning off mobile data/wifi when you don't use it significantly reduces android system and android os usage.
it isn't really a solution, but it is a work around.

I also have a problem I posted this on another members thread -
I have also had this problem, I have not changed many settings since day 1 of owning this phone - nfc data bluetooth & sync off, Wifi scanning all the time only when charging & drains so much during the night! Last night I was on 42% at 21:50 then at 22:50 it was on 23% then at 23:50 it was on 15% & at that point I put ultra power saver on, which said I would have 1 day of power left.... I checked again at about 01:00 & my phone had run out of battery & shut down! Today I am taking back my phone to the shop & am demanding a new handset, I think I may have just had a faulty S5? Also my phone was getting quite hot at night in my pocket & also had a problem sometimes when powering on with the power button to wake the phone nothing happens & got stuck in ultra power mode a few times & rebooted? Other than this I love the S5 & hope my new handset is perfect? IT BETTER BE? [emoji35]

I have also had this problem, I have not changed many settings since day 1 of owning this phone - nfc data bluetooth & sync off, Wifi scanning all the time only when charging & drains so much during the night! Last night I was on 42% at 21:50 then at 22:50 it was on 23% then at 23:50 it was on 15% & at that point I put ultra power saver on, which said I would have 1 day of power left.... I checked again at about 01:00 & my phone had run out of battery & shut down! Today I am taking back my phone to the shop & am demanding a new handset, I think I may have just had a faulty S5? Also my phone was getting quite hot at night in my pocket & also had a problem sometimes when powering on with the power button to wake the phone nothing happens & got stuck in ultra power mode a few times & rebooted? Other than this I love the S5 & hope my new handset is perfect? IT BETTER BE? [emoji35]

Let me know if they give you a new handset...
I sent an email to support, they told me to bring the device to the lab to get it checked....
cant they just give me a new one and thats it? -_- ughh

Went to the EE shop like I was told on the phone from customer services but they were unhelpful & then had to phone customer services back but then all they could do was send me another battery & not give me another handset yet! but not until after the weekend which by then my 14day return with no questions asked would be up & I would be bound to a contract for 24 months.... So i told them to stick there contract & thanks for wasting my time & lieing to me, so gone over to O2 contract a few hrs later & I must say I am happier with them, I even asked if they could unlock my phone to any use any sim & was told just ring customer services & they will do it free of charge!!!! (I was very surprised), anyway charged my battery for about 6 or & a half hrs & have had 22hrs battery life so far with loads of Web viewing, Wifi on most of the time & still have 27%. Loving this phone [emoji106]

umm AVG is chewing up all your battery dude.
uninstall that junk and find a AV thats light on battery. i use Dr.Web light which has always done be well and uses next to no battery
do you have "restrict background data" ticked on power saving?
and yeah make sure GPS, Bluetooth is off too, only use when needed.
my battery on my s5 lasts 2 days of fairly heavy use

Just get all that garbage off, you dont need an AV on your phone, its not that hard to not get it infected unless you are downloading apks willy nilly, its not windows...

S5 Worst battery ever

Got this phone about 10 days ago and my battery is terrible since day 1, someone suggested to root my phone and get the BBS app and dump a file i did that and installed a system tuner to disable google CHECKIN OR GCM and unchecked them. apps i got installed to help with battery battery doctor, wakelock detector, os monitor, system tuner, gsam battery, betterbatterystats.
Apps i disabled are:
Ant radio service
Ant+ plugins
App zone
Blurbcheckout
chaton
chrome
flipboard
google play book, games, movies, music, newstand , google search, google+ , hangouts
hp print service plugin
my magazine
s health , svoice , samsung account , samsung apps , samsung galaxy apps widget, samsung push service, smart remote , Top Hd Games
got a plain black wallpaper, even after all this i cant get more than 2h30m screentime and everyone is getting 5h+ do i have a defective unit? what are my options right now? cause basically i removed everything the phone has lol. i talk to my workplace and they can send the phone for repair but i want to see if someone can help me before i do that. i have to unroot the phone if i have to send it for repair even though my phone is 0x1 on knox cause i was stupid to root with cf-root and didnt check other methods.

After all that you did, then it sounds like a faulty battery or device.

How's your signal at work? I'm on 3g at half signal maybe? I get about 3:30 and standby. But when I'm at home WIFI only I get about 4-4:30 it all depends too on how bright your screen is.

How do I check if I have a good signal at work? Through an app or through a battery status.

This system tuner app you used it not any overclocking or something that might drain you battery?
What screen brightness do you use most of the time?
Can you see what use most of your battery? There is charts you can access in settings -> battery
I run with BLAZE kernel and Alliance ROM. (install without any samsung or google bloat if you can)
And I have been using my phone constantly, playing streemed music, installing apps, downloading from internet, browsing internet, having screen active a lot...
And Now I'm at 87% and have been running 1 hour and 38 minutes on battery. (Was at about 100% battery before)
I run +5 screen brightness and don't have any special powersaving features running that limit my experience with the phone.
You could try that kernel and ROM too, I feel they improved my battery time a lot.
I also shut down some samsung and google bloat stuff like air browse, s voice and such crap, saving a little little battery.

Here is my battery info and my brightness level. I have Canadian g900w from Rogers so I am not sure what roms or kernels you can use ?

Hey, here I have everything turned on and I never followed these stupid extreme battery guides and I easily get over 4 hours of screen time and one day away from the charger. I only use auto brightness, Greenify and KT Kernel.
It's a smartphone, if you're supposed to turn all the features off then you should have bought a dumb feature phone.

Looks like ur using max brightness? Nearly 2 hours screen on time for 44% isnt the best but isnt terrible. I get around 5 to 6 hours using low brightness 3g/4g on besides when screen on. Using android tuner and greenify for tuneing. Screen uses a lot of battery to. Im using. Ktoons kernal now with oc and the batterys probably the same to to me. No beter or worse but. Im running higher clock.

You're set for almost four hours of screen on time there, on what seems to be very poor mobile signal. Doesn't sound that unrealistic to me to be honest.
Poor mobile signal absolutely kills battery life, as your phone spends the entire time searching and trying to get a better signal.

I think his point is that most people get 5-6 hours screen time with everything on and without following the "stupid extreme battery guides". To be honest it looks like you aren't getting great life either if you are only getting 4 hours. I regularly get 6-7 with everything on and no greenify or kernel tweaks

I see a couple of things interesting with your setup, Speaking from personal experience, I too have had battery issues drive me up a wall. I'd get just about a day on a battery when everyone else gets about 3-9 days more. My friend has an s5 all stock and he gets 9 days on a freaking battery. WTF
I rooted my first s5, with ANCH baseband and still couldn't solve all the issues with it. So I sent it back to t-mo and they sent me another one, getting batteries on ebay has also ended up a wash. 2 batteries I've received go down 20% from a full charge in the first hour and shut completely down at 32 percent at least I got a refund on that. (So be careful about ebay batteries, even though they say samsung.
So looking at yours here's what I see, Your system is staying awake, lets look at wake locks. Kik is really tearing up your machines wakelock (900wake locks) as well as the camera CPU time, i'd imagine you were recording a video at some point.
1. Go get greenify and greenify those Kik, Instagram and camera apps if thats usage while the screen is off. (No notifications on those apps, i'm afraid when you do that.)
2. Go get system tuner, make sure your rooted by towelroot (If you so choose to keep from tripping knox) and go into app mgr and find android system and go through activities, receivers and services and make sure everything you see that says IQAgent gets unchecked. This will help you stay out of ServiceIQ's eyes and also help your battery as your entire phone is debugged through those apps. (Help is on the forums somewhere)
3. Turn off google now, hotword detection and location history or you'll start noticing Google services draining your battery
4. Go get deep sleep battery saver and remove that battery saver, I personally never liked it it only suggests things to do rather than do them for you. At night or whenever you need to save your battery turn on slumber and it will only take like a percent to 5% in the morning
5. You probably have a bad battery, especially if its down to that low. Time to exchange or return
I'm incredibly disappointed, i've had to do all these things to really figure things out, heck i'd be on firefox for about 15 minutes and go down 18% (Happened this morning)
Android really has some issues with kitkat, and even though we try and fix these problems with modifications there comes a point where one just gives up and tries to deal with it.
I don't understand why my phone gets 1.2 days and my co-workers Verizon s5 gets 9 days with normal usage. Everyone seems to have crazy all over the scale battery life results. Heck, i've reset my phone and flashed so many roms that i'd be safe to say that I have yet to have 10 full discharges in the 4 weeks i've had the phone. At the end of the day though, it's mountains better than my iphone 5 with a lenmar battery case.
Wish I could say the same with stability, I'd be on my bike and switch tracks (or try) and stuff just doesn't respond, heck I can't even go with voice activation with wired headphones and that is really a downer for me. I want to be able to hold down the pause and play and get the google now boop boop sound and speak as i'm riding.
I'm tired of this, and google has no answers, the fixes above only seem to add a couple of hours but not the 9 days I was seeing.

So? What do you do to have that many hours? Which rom? How often do you recharge? Which apps do you use? That's the point. I never freeze/uninstall anything...

My rom. With nothing removed or frozen as I have to keep all bloat due to development to check everything. I recharge every night usually with about 20% left and about 5h30 screen on. Using Tapatalk, music, calls, Internet. The usual stuff.
Sent from my SM-G900F using Tapatalk

I get 6-7 hours normal use with the bloatware I never use frozen. And I mean never use.
Gtalk, whatsapp, line, google drive, dropbox, gmail, Yahoo mail, corporate mail, all running. No greenify. No battery saver.
Now playing games is different thing. 2-3 hours max.

My battery is amazing. I keep the screen brightness lower, keep networks and chips off when not using, i use bootmanager to prevent apps from launching ay boot and only 1 active widget. Good for a day and a half of very fair use !

Yup probably, the only flaw with a smartphone is its user
