Extreme NFC usage? Possible? - T-Mobile Samsung Galaxy S 4

My battery has been draining at an abnormal rate, extremely fast for me.
The NFC service or whatnot is the main culprit.
Read what I mean below and I have the screenshots to show what I mean too.
***Full disclosure, I do not game at all, I do not watch any videos, I do not listen to music when I was doing these tests nso as not to skew the results.
As said above, my battery has been on this downward spiral out of nowhere.
It started a few weeks ago with the foxhound ROM v 0.5. I turned on my phone one day and my battery just went to hell over night.
I was on a full charge expecting like always that I would at least get a good 5-6 days out of 100% charge, but overnight, the battery went from 100% to 10%. I know everyone's battery is different but I mean really from 100 to 10% in just under 7 hours? Damn.
So I thought it was the ROM's problem. Naturally, I Nandroid' the whole foxhound v0.5 ROM and flashed another ROM.
The next ROM I flashed was the SOKP ROM to make sure it was just the ROM's problem. I updated my baseband to NB4 at the same time from the MLK baseband. I let it sit for a couple of days and use it a I normally would, just using FB and going online, no games, no music, and no videos watched.
The battery life was fine for a coupla days and then all of a sudden it happened again. It went from a 100% full charge to 5% overnight.
So then I checked and nothing was wrong, thinking it was the ROM again, so I flashed another ROM, Hyperdrive ROM, and the same thing happens again. It's driving me nuts.
The NFC usage taken from screenshots from the different ROM's are just insane and they show what I mean. Nothing was being used as can be seen. No games or anything like that.
I was wondering if anyone is able to help me out with this singular problem?
Has anyone ever experienced anything similar? I know each battery for each S 4 is different but damn 100 to 10% overnight, I mean...
Is there any way that I could throw up a log for you guys or something to see whats draining or using the NFC so much?
I've attached screenshots that were taken showing what I meant above. These screenshots are taken from when the phone is performing during its better days where I could get up to 1 whole day of usage.

Do you use NFC at all? If not, just go into your settings and turn it off. If you do use it, you could just turn it off when you don't expect to use it, and switch it back on before you need it.

I don't use NFC and I have to manually force close it every time because it just turns on of its own accord. Every time I turn it off,
it just turns on again without my doing anything. And even with NFC off, it still appears on the BBS's app and Battery's under Setting's saying that is running still.

I never have a problem with that personally, but I would say use Titanium Backup and freeze everything that has NFC in the name.

I froze anything that remotely had NFC in the name after doing a Titanium Backup search and the battery is still draining, but just a bit slower than before.

I would try flashing stock firmware with Odin, NFC should not be draining like that and you shouldn't have to freeze everything

Any way how? I'm thinking about flashing 4.2.2 again with Odin. I'm still on 4.2.2 on the FW side, I haven't upgraded to 4.4.2 or higher. I just flashed the most recent version of ROM's that has 4.4.2
Do I have to root again after flashing stock FW? I don't want to go to android 4.4.4 what with all the Knox and stuff that its being hit with.
Also, is there any link to past android FW versions? I can't seem to find any.

Yeah since you never updated past 4.2.2 you can still flash the 4.2.2 firmware, get it at sammobile.com

I tried to find it there but all I come up with is the 4.4.4 version?
Nothing older than 4.4.4
Edit: found it, will Odin it and see what happens.
Do I have to do a full wipe of everything? on the internal and external SD card?

No, just a factory reset but do it before you Odin

Do you mean factory reset through the custom recovery? ie using TWRP or CWM?

Yes

Gotcha
Was wondering will I need to re-root the phone again after going back to stock?
Confused by a reply earlier.

Yes you will need to re-root

will keep updated after a few more days of usage to see if any changes occur.
thanks for you guys' help so far!

[Q] help to calibrate battery *using dif metod*

I had try the metod of pluging in and off the charger and cleaning the battery data but i didnt work. I deactivate widgets and everythig but battery still draining iys another metod that i can use to recalibrate my battery? Thanks, i already read all prior post
Have you checked to see if anything is constantly syncing? Checked your partial wake usage? What about monitoring in System Panel?
Are you from Glenview, Illinois? I grew up there, live in Northbrook now.
Well i guess is not another way to solve this
Oh cool man and yeah all the sync its off and all the other stuff i just start having this issue after install the new king kernel ( bad idea ).

way to give up buddy.
a billion people have an htc evo who at one time had battery issues and fixed them, but there is absolutely NO way to solve YOUR battery problem.
There are a ton of variables as to why your battery drains. What rom are you running, if any custom rom at all? Kernel? Theme? Whats your screen brightness setting, or your screen off time? Do you watch a lot of movies? Are you on the internet all day? Is your GPS on or off? Is your blue-tooth on or off? How much time do you spend on facebook? how much time on Twitter? How far are you away from a tower? How strong of a signal do you have? etc etc ETC
Edit: Ok cool, well can you flash back to your previous kernel and see if things get better again?
hmm... have you tried flashing back to your last known good config? Did you do a nandroid before flashing the kernel? What kernel were you using before that was working? Have you tried flashing that one?
Yes i did all my reading before posting im using the stock rom, with the stock kernel now. I did not jave this issue before my battery was perfect until i flash the king kernel and yes i use a back up and flash it but i did not work
I just wanna know if its another metod to recalibrate the battery besides just pluging in and pluging off the cellphone
I just wanna know if its another metod of recalibrate the battery besides pluging in and pluging off the cellphone
You can wipe your battery stats in recovery, but I don't think that will help TBQH.
If something is draining your battery you need to do some detective work to figure out what is doing it. My first post in this thread suggests a couple things to start with.
Yes friend i did that already mmm i guess im gonna try with another battery to see what happened
Your problem is in kings kernel, i know he was working on it not sure if he has solved it, try the cfs 10 one.
Sent from my PC36100 using XDA App
That was his new release isnt? Thats the one i used and screw everythig :-(
Try reflashing it, maybe it will work then? How long ago did you flash to this new kernel?
Maybe you could give it a couple charging cycles just to be sure. Work with it for a week or so, letting the battery charge down, and then charging it back up again a couple times.
thanks for the tip im gonna do this but with the stock kernel i seems today it last a lil longer i was sufing, texting, even playing and making calls and it last me 7 hrs with out charging. i uninstall sport tap though i read something about that app that use to much conection

i am pretty sure is problem is flashing a custom kernel with a stock rom, other way round (stock kernel with custom rom) probably fine, but i am getting off point, i have never been able to get my battery to reset properly, but on my phone its just a minor annoyance. the only way i have found that comes close
first of all i would really suggest you switch to amon ra if your not already useing it
(also you must do all this in one recovery booting so make sure you have good battery/ phone plugged in)
1. wipe battery data (again the same way you did)
2. factory reset phone wipe data davilik all that then do the battery again
3. flash http://api.viglink.com/api/click?fo.../font></div>&jsonp=vglnk_jsonp_13176886532531
this will wipe your phone
4. flash http://api.viglink.com/api/click?fo...en_Lightning&jsonp=vglnk_jsonp_13176887115882
this is your new rom, and kernel, its all in one. it should fix any battery problems because superwipe will destroy extremely completely anything on your phone,
PS. if you want to keep your contacts and applications, before you do anything above, go to the market and download my backup root and make backups of your contacts and applications, then when you do it all download it again from the market and bam you got all ur stuff

Insane bad battery life - high usage from "Android system"

I'm getting quite annoyed with my S3 and its piss poor battery life - currently seeing as little as 5 hours. On average, 55% of my battery goes to "Android System". I've tried a variety of battery monitors, but none can dig deep enough to determine which of the processes under Android System are sucking up all my juice. I'm on stock (rooted) and have tried to uninstall as much as I can (including the notorious Google+). Any tips on an app that can determine exactly which process is draining? I've also disabled as many Samsung apps as I can. I *did* try CM10 for a bit, but too many small things were not working right, so I nandroid'ed back to stock again.

I had this problem numerous times before. If it is Android System that is taking up battery, then its most probably a bad kernel. Your nandroid backup probably was bad. (it sucks, i know). Redownload the stock rom, flash it in odin, before starting up reboot in recovery and factory reset, then start it up. Your problem should be resolved. dont restore any apps and start fresh. Like I said it sucks but what can you do?
Hey ScottC,
Definitely doesn't sound normal. At the end of the day, I'm sitting around 10% lost to android system, 15% tops (of course this can vary on what you use and how you use it, but if your battery dies in 5 hours, certainly something is wrong). It's possible that in the process of nandroiding back, something messed up. I'd recommend a complete wipe (factory reset, wipe dalvik, etc), then test it out for a day or two. If the issue persists, you will likely want to Odin back to stock. If it still persists (highly unlikely), I'd call in for an exchange. Best of luck to you, and please let us know the results!
Thanks for the tips - to clarify, it was doing this before I ever nandroided back - but I have a feeling wiping might be the best bet (or trying out a better JB leak).
I think you may be getting the gsiff_daemon bug. Next time you have the battery start draining like that, turn on show cpu usage under developer options in settings. If you see gsiff_daemon at the top, then that's what's causing the android system battery suck.
The fix is simple go to /system/bin with a root explorer, mount r/w and rename gsiff_daemon to .Bak or delete it. This won't hurt anything. Then reboot.
There is a thread about this in QA. If you check it out keep in mind it's full of wags and speculation.

I have the same issue. My phone was 100 percent and I've been sitting here watching the Texans game and I'm getting the worst battery life today that I have in my week or so of owning this phone. My phone is bone stock.

Add another one to the list for this problem. I've had my phone since Sept. 27th (so 3 weeks?) and up until about 4 days ago it was great. Great battery life, even with all the bells and whistles turned on, and several apps that update constantly. For some reason a few days ago it started to battery drain HARD, downing to 25% of the battery life in less than 6 hours. That's with the phone sitting idle, not touching it, on wi-fi (not 4G) with excellent signal. Last night I plugged the phone in at 10% battery, did some chores, and returned some 3 hours later to find the battery at 5%. It drained while it was plugged in!
The battery drain issue seemed to start after the phone decided to have a certain level of diffuculty finding a 4G signal. I had to reboot the phone to get it to connect to the network. After that, the Android System will take anywhere from 55% to 76% of the battery drain.
I have shut off numerous programs, disabled the Samsung apps that were said to possibly be a problem, and looked for the gsiff_daemon in the CPU list (my top process is "com.android.systemui"). I searched com.android.systemui to see if I could find a fix, and all I'm really seeing is "flash a new ROM" or "Your kernal is bad, reset or reflash it." I'm running a 100% stock phone, and actually had no intention of rooting or flashing this phone yet, and I didn't want to have to factory default it. It's starting to look like that's my only option. Someone said that this bug seems to crop up out of pure chance and I think they may be right. My husband has the identical phone, bought, charged and activated the same day, and he doesn't have this problem. He's still getting the incredible battery life that I used to get.
So what's the skinny? Is my only option on this a factory reset? I've seen threads referrring to a thread dedicated to this topic, yet no links. If there's more info to be found, I'd love to read it.
This thread might as well be titled "all noobs thread". It is known widely that android system in jb leaks is a problem but of course u cant know that cuz reading and searching are two words that sound like chinese to you.

Actually I have "searched" and "read". I wouldn't have posted had I been able to find an answer. Everything I've found has been for ROOTED/FLASHED ROMs, and I'm on stock. I don't want to root/flash this phone, I'd like to fix it without having to return it or factory default it if possible. I also mentioned that I had gone through threads and tried as many of the tips there that applied to my situation.
While I'm not nearly the level of many here, I'm also not a n00b. I've flashed, rooted and hacked many devices, I'm just trying to avoid that here. I didn't run across anything called "jb leaks" in my search, so if you'd care to be helpful and elaborate on that term, it might prove useful.
I believe this is the thread you were told about.
http://forum.xda-developers.com/showthread.php?t=1755180
When you checked cpu use, how did you check it? There's an option in Dev Options to Show CPU Usage and you can see real time what's running. Just fyi in case you did it differently.
Sent from my SGH-T999 using xda app-developers app
Thanks for the Link, Doc! It's much appreciated. As far as checking the CPU, I used the option under the Dev Options menu and watched it bounce about. Many different programs would take top spot, but when the phone was idling it was always com.android.systemui at the top. When it wasn't top, it was never far below.
Have you tried booting into recovery and wiping dalvik cache?
If it comes to it, before factory resetting since you want to avoid that, download the official stock FW and flash with Odin. I'm pretty sure it will keep your data and apps intact. Backup data first in case I'm remembering wrong. If that doesn't do it then factory reset may be your final option.
Check settings > Battery, and open Android System (I'm betting its at the top). This may give you a better idea of what the root cause could be, maybe...

You are not the op of this thread so i cannot comment about your problems. The first posts regard rooted devices running jb leaked roms and in the jb leaked roms threads all people talk about is android system taking a high percentage of the battery usage. So one must be really blind not to notice what is the problem and fix if there is any. There is no fix and it is kernel issue. Thats the reason why it is called leak and not official release. U can post some screenshots of ur battery usage and firmware version you are running if u want people to help u since u claim u r all stock and still android system usage is high 76%.
Doc-
I tried booting into recovery, but since I'm not a rooted user I can't clear the delvick cache. Somehow in the process of attempting booting into recovery I managed to lose my set wallpaper and most of my homescreen widgets, though the rest of my data and programs seem perfectly intact (accidentally went into a safe mode option). I did clear the cache partition in recovery, and tried another trick someone listed of pulling the battery and holding down the power key (I'll try anything at this point) and oddly it seems to be behaving better so far. Sitting on my desk it didn't discharge at all, and having just put all my widgets back it's only drained a few points. The screen is now the big spender at 39% with Cell Standby next at 12% (previously is was Android System being the hog at 50-70%). I have no idea which of the things I did actually did anything, but I think this just saved my tail.
I'm going to charge the phone normally tonight and leave it loose all day tomorrow like I usually do, and see what happens. If it starts battery draining again, I'm going to try flashing with Odin. Here's hoping I'm one of the few lucky ones where the problem simply "goes away".
Thanks again for your help!
Well that's kinda weird...good, but weird!
I've heard of people going into safe mode but its never intentional and I've never found how to do so at will.
As long as it goes back to normal though! Hope it does! Good luck!

I know that this sounds pretty simple and you may have already tried this, but it always works like a charm for me. Try draining the battery ALL the way down until it automatically shuts off. Then keep turning it on until it won't even turn on our vibrate anymore. Plug it in and turn it on. Leave it plugged in until it's at 100% again, I do this overnight so there's no usage other than standby. Hopefully this will get your battery back in shape. Good luck!

Sometimes I wonder how I got into Safe mode.
forum.xda-developers.com/showthread.php?t=1821557
Well, It behaved for about an hour, then it started the massive drain again. Sadly I just backed a few things up and then factory defaulted it. We're leaving on a trip tomorrow, and I need it to not be a power-sucking brick. Oddly, everything that my CPU report was showing was identical to my husban'd phone, which has no issues with battery life. The Gsiff daemon never once showed up.
As far as safe mode, I held down the volume down button while I powered up the phone. It went into safe mode. Don't know if it'll work for y'all, or if it was just a fluke on my part. :>
Thank everyone for your help in trying to troubleshoot this. One of these days I'd love to have an electronic device that just worked without me having to poke around in it's guts. ;>
If its still acting up after the factory reset, your best bet is to flash the stock FW with Odin. If the factory reset didn't wipe your internal sdcard, you may need to to wipe it in recovery by using format data as well. (Factory reset should do this anyway as long as you're on stock recovery)
I've seen on some jb leaks where this would significantly help. I know your not using jb but its worth mentioning anyway.
Good luck!

Bad Battery Life since KitKat

Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.
I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.
Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?
I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.
Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

Just checked. Governor is set to interactive. It's also the default setting.
I sadly don't have a backup battery.
It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.
Mine is pretty bad but it's running google play to death so maybe gapps flash was bad? dunno

this maybe issue of ram management.. try some good apps to control those background & foreground app from running without control. dont use any task killer.. please
i recommend using greenify.apk. donate version much better.
sorry for my bad english

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?
Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...
So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

are u sure greenify didnt helping??? already got rooted & exposed installer running??
can u state your screen on time??
usually gnex can handle 3-4 hour screen on depend on battery condition n phone performance... not include idle n stanby time.

if u lightweight user, i suggest u to optimized performance. use apps such trickster mod, rom toolbox, or in addition of any light battery saving apps ( for optimization)
should be improve on screen time.

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:
http://forum.xda-developers.com/showthread.php?t=2519294
I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.
i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

Battery Problems (After Bricking??)

Alright so I've been doing research online this week and haven't been able to fix it so I'm coming to you guys. I'll give you a little background to hopefully help speed up this process.
So about 3 weeks ago I rooted my Sprint LG Optimus G after having it for almost a year to get some better performance and battery life out of it. After getting it all setup, I noticed a huge difference and was even able to watch the movie Flight and two episodes of Family Guy off Netflix and my battery still lasted 9 hours that day.
Well last weekend after uninstalling some Google apps I soft bricked my phone. Thanks to the help of sawdey21 on the IRC I was able to get it back up and running with LGNPST. After getting it running, I switched launchers (from Holo to Nova) and also unlocked mine phone via FreeGee with TWRP. Since then, my battery life has been terrible. To give you a reference it took my phone 8 hours to fully charge last night while it was off (although since I unlocked it I have a new charging animation and after a few seconds of the animation, instead of shutting the screen off like it use to it now just goes to a black screen but is still on as you can see the brightness. It never shuts off). After unplugging it, an hourly later I was down almost 15% after just listening to music and after 4.5 hrs its at 30% and I just plugged it in. Today I have done nothing but listen to music and just period check/browse my phone.
Is it possible that the bricking messed up my battery? Or the unlock? I switched back to the previous Holo launcher I was using before and it made no difference. I've also unistalled several apps I downloaded since the bricking I thought could be causing it.
Has anyone ran into this or could help? My next step is to boot back into Download Mode and try LGNPST again. I would post pics of Battery Settings, WakeLocker and BetterBatteryStats but I can't since I'm a new comer.
Thanks!

I'm not 100% sure but it is possible the bricking messed with the battery. LGNPSTing back to stock could have affected it, anytime you flash a new rom it takes a couple of days to "settle in" but you said last weekend so it should be settled by now.
But from your info, it may be the way you are charging it. There is a common misconception that every so often you are supposed to let your battery drain fully and then charge to 100%. This is only true for nickel based batteries, ours is lithium so this is in fact quite detrimental. Lithium batteries are built to be charged often and you should never let it dip too far into the red. Doing so decreases the life and performance of your battery significantly. 5% is as low as I'll let my battery dip before charging and even that is pushing it imo. There is an app in the play store called battery calibration that actually tells you to do this, but like I said, it's only useful for nickel based rechargeable batteries. Also this same app's function is deleting the batterystats.bin file in order to "recalibrate" the battery. This is also completely false as that file has nothing to do with how well your battery performs.
I wouldn't turn the phone off to charge, just charge it while it's still on so the screen actually shuts off. Checking your wakelocks and using greenify on power hungry apps will go a long way. I also turn my capacitive buttons off because I don't need to see them to know left, right, center and what they do. And if I'm not using it, it is always off, sync, gps, brightness when inside, etc. But as I said, it may have been the way you were charging it, it might not affect the battery for months, then all of a sudden your battery doesn't perform as well because it's dying due to improper charging techniques. And when you LGNPSTed back to stock, your system tries to start fresh which is why it may have happened immediately afterwards.
I hope some of this helps you - if using greenify doesnt show improvement you may want to buy a bigger capacity battery and start fresh. Installing the new battery is tricky however, there are youtube videos on how to do it, but it may not be for everyone.
Good luck and I'm sorry if I assumed too much or misread your info!
EDIT: You may also want to try flashing a different stock kernel(I use Viper1.1, my signature has a link to the thread) and using trickstermod to undervolt the cpu. The improvement is minimal but every little bit helps. On average I get a full 24 hours in between charges and usually charge once it hits 10-15%. And it only takes about 60-120 minutes to fully charge.
However the lgog is also very fickle, what works for one may not work on another, even if it's the exact same model. Many people have reported the same security bootloop soft brick after deleting google apps for instance, but I deleted(not frozen or disabled) google apps just fine. The only ones I have on my phone are play store and google search and I'm still on stock zvc.
HPTesta,
Appreciate the response and all the info. To clarify a little more, I've never installed a custom ROM. Just been doing launchers from the Play Store besides having to do the LGNPST. As far as Apps I've been using greenify since I rooted 3 weeks ago as well as CPU Tuner which had both been doing great for me before this.
As far as charging goes, I generally never run my phone compleley dead. I usually charge when its getting low but last night I ran it complete lay dead to use Wake locker (read in the app store to drain bat, recharge full, and use after a couple hrs.
One thing I did find weird is that I don't remember how much battery I had when I bricked it but after doing the LGNPST I had 0 (Don't know if that's normal).
Also, never used the Battery Calibration app.
And based off what your saying would you not recommend doing LGNPOST again?

Ok well it seems like you follow good battery techniques. Maybe try LGNPSTing back to a full stock zvc(or zvb and then updating to zvc) and charge it to 100%(let it sit at 100% while still charging for 15 mintues or so) before rerooting and unlocking. I would probably also copy your internal to your pc and wipe everything in recovery before doing LGNPST just to make sure it is a completely clean slate. I added an edit in my post above as well.
I had a strange issue a few weeks back where I tried overclocking my cpu with AK kernel - my battery was at 99%. My phone shut off and wouldn't come back on, just had a red blinking light. I later found out it was an issue with AK. I charged it for a few minutes and luckily was able to get into TWRP. The strange part was that when I did get into TWRP my battery read 0%, I did a full wipe and restored my backup, then my battery read 99% in TWRP. It's a different issue from yours but makes me think that it's possible that your softbrick and LGNPSTing affected it somehow.

I honestly have not had or heard of any issues with LGNPST and battery performance. Anytime Ive had to use LGNPST with a full stock .bin, it essentially set my phone back to factory condition, battery performance included. However since this all happened when you did this, maybe try flashing another rom first, even a stock based one and leave LGNPST as a last resort. Just make sure you read the instructions for whatever rom you decide to test and always do a full wipe(data, cache, dalvik and system) before flashing.
EDIT: Sorry if it seems like I gave you conflicting info, if it was me I would probably be weary of using LGNPST again, personally. But if I tried flashing other things, different recoveries, roms and still had the same issue, maybe it was just a slightly messed up LGNPST flash and would try it again as a last resort.
Forgive my ignorance but I've never actually booted into twrp recovery. Its volume up and power but where do you go from their to wipe?

After holding volume up + power, you then will hit volume down twice and power again. Once in TWRP it is very easy, there is an install button, wipe button, etc. Hit the backup button, pick all available options and then do a backup and reboot into your OS. From there, download a rom(optimus DE is a great stock rom) to your internal and you will probably need gapps as well(depends on rom but almost all of them need gapps or you wont even have the play store - just read the install instructions of the rom). Go back into recovery, This is under the advanced wipe button in the wipe menu - wipe everything except internal storage(if you wipe internal you will lose your backup, pictures, music, etc) and then go to install, pick the rom.zip and flash that, then pick the gapps zip and flash that as well.
Also keep in mind that if you flash an AOSP or CM based rom, the file system will be different. Our internal storage is /data/media but for AOSP based it is /data/media/0. So say for instance you make a backup in TWRP of your stock then flash an AOSP rom, it will look as if your internal is gone as well as your backup. You will just have to use a root file explorer to copy the /data/media/TWRP folder to /data/media/0/TWRP and then you will be able to restore your backup from TWRP.
If you are just going to try LGNPST again then when you get into TWRP pick everything including internal and turn the phone off and put the phone into dl mode(you know what you are doing from there).
One final note, if you are using current FreeGee to unlock then you are most likely using the updated TWRP. Some people have had SEVERE issues with it, for others it works just fine. You need it to install any rom based on Android 4.4 but I personally use TWRP 2.5.0.0 which will flash stock to Android 4.3 roms just fine and it is rock solid stable. So unless you are planning on installing a kit kat rom, I would first download the TWRP 2.5.0.0 zip found here to your internal, go into twrp, pick the install button, find the .zip file and install that, then go to reboot in TWRP's main menu and choose recovery instead of system. TWRP should now read 2.5.0.0.
Sorry for the books I'm writing here but I think it's always best to be thorough!! And I haven't slept in about 30 hours so I am a bit scatter brained.

[Q] 4.4.2 Battery Life issues - less than 25% total life compared to previous version

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything
Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I stumbled across this post and tried that fix. I'll check back in later to see what it does.
