[Q] Battery drain: mystery network usage?

I'm running CM6.1 RC2, and the past couple of days I have experienced excessive drain, mainly in the first 50%. I attached a picture of the issue. I went to spare parts battery history to see the network usage, since in the about phone battery usage cell standby was 84% of the battery usage, and under network usage there was just an entry for 0, using the most network. When I clicked on '0' the settings application crashed. Yesterday it dropped 35% in 2.5 hours, before it slowed down. It was ridiculous, never used to have this problem, and the battery is only a couple of weeks old so it has to be software. Today it is at 53% after 7.5 hours, which is pretty decent, but at around 70% I disabled 3g and background data to save some energy for a few hours. Is there any way of figuring out what is causing this, or should I reflash? Could it be a CM6.1 RC2 bug? Anyone else having this issue? Thanks in advance
BTW I have no idea why the dialer was so high in usage I only had like MAYBE 15 minutes total of voice calls in 2 hours. The 0 is what I'm concerned about.

Anyone? Bump? No one else is having the issue? Still happening to me on RC3.

I've been getting that problem too.
I used to have battery life of up to 4 days (Mostly standby), now I'm lucky if I get 1.5 (Same usage).
I went in to spare parts and it crashed for me too.

Battery drain here too since cm 6.1

Well '0' is he system's ID, 0 is root. In the graph the blue is bytes sent, red is bytes received. Have you checked other usage like CPU usage? That might be a better indicator of what's using your battery. Then from there you can start to narrow it down to a specific process or app. I'm using the latest nightly and don't have that issue, never have. I use a bit more battery than I think I should but nothing crazy.
Do you have wifi or bluetooth on? Those drain your battery like no other.

I havent used wifi at all today, unplugged at around 6:30, it's 3:45 now and I'm at 63%, but from around 9:50 to 11:45 and then from 12:20 to 2:20 I had airplane mode enabled since the time without a signal was at 70%, very low signal area. So it seems like for only 4 hours or maybe 5~ of non airplane mode time I should be at above 63%. I only had wifi on for a half an hour today. I'm considering going back to stock for a few days just to see the battery life comparison, and then nandroiding back to CM6.1. I always end up going back to AOSP-based roms in the end. I don't have a data plan on my phone at the moment, getting it today I'm pretty sure, so could all of the blue be from the phone continuously trying to access a website? But other people said they have the same issue and I'm assuming that they have data plans, so that can't be too much related. Hmm.
I also checked cpu usage and such like you suggested, there were a lot of things listed but all but two of them were too small to even have a bar. The two that did have a bar visible were minuscule to put it lightly, so that can't be an issue. Battery use in the about phone area always has cell standby at the top, normally between 40 and 80%. It would seem like there is way too much cell communication going on, moreso than normal. Cell standby stays at the top in even high signal areas, so it's not the signal levels. Kind of stumped here.

Well if the cell is in standby then it's linked to a tower and awaiting activity. Every now and then it 'checks in'. If it's doing that too often then that could seriously drain the battery. You're right though, I'd just switch back. Trouble shooting the exact issue wouldn't be worth the time. Maybe try flashing it again later, could have just been a corrupt download that didn't flash properly.

After conditioning my battery religiously (full to empty with every charge cycle) I am back up to about 15 to 16 hours from full battery to system shut down which is way better than the 10-12 hours I was getting when I first loaded RC2. CR_OTA ROM gave me up to 24-30 hours off of one charge with the exact CPU/2g/3g/wi-fi "routine" as I am using with RC2. Tracked battery usage with System Panel app and RC2 has a steady and even drain pattern ... an even diagonal line down the graph (100% to 0%). Cell standby uses a ridiculous 40% of the battery from full charge! On the stock ROM System Panel app shows plateaus throughout the day when the phone screen is off/sleeping where battery use is virtually non-existent. I'm going to load RC3 today and track the cell standby and battery usage. This time I am not going to use setCPU and just let the ROM run as the CM team designed it to be used and see if anything has changed. I tried this with RC2 and the battery still trended absolutely evenly from 100% to 0%. I can live with a 16 hour battery cycle for the CM ROM because it is very smooth and never has a glitch. The stock ROM is smooth as well but it has some buggy behaviors that I just cannot stand for and it does not run the latest GAPPS.

I've noticed i have exacly the same problem(was actually gonna post it when i found this thread)
Needless to say that on eclair my battery lasted ~48 hours constantly, not its drained in max 24...

The highest I have EVER gotten was 24 hours, and that was on a cm6.1 nightly build, pre RC2. I loaded cr_mod and experienced a HUGE drain. I had airplane mode on, just to test, and it dropped 7% in an hour, in AIRPLANE mode, with no screen on time. I went into spare parts and looked at the usage, and sure enough, "running" was at the top, with 99% of the time spent without sleeping. This has never happened before though, so I can probably attribute that to my modifications. I deleted a few apk's and de-odexed it before I flashed it, and I have a feeling something I did corrupted something else, so I'll flash plain old cr_mod and see where that leaves me. I should probably get back into the habit of full charge/drain every cycle. I used to do that until my battery started lasting longer than I was awake for, so I always had to plug it in at around 15 to 30%. I'll run some more "trials" and see what's going on.
Also, on an unrelated note, I love the stock rom, I always love the sense UI, but I hate HTC_IME compared to the froyo Latin_IME, is there any way at all I could port the froyo Latin_IME to the eclair stock rom?
Edit: also, I flashed dumfuq's OC kernel over cr_mod, could that have been the culprit to the battery drain?

Shouldn't be the culprit. It would drain quicker because of the clock speed but shouldn't be too bad.
Yes Latin_IME should be able to be used with sense. Just delete htc_ime and clicker.apk then install latin_ime and it's corresponding clicker.apk which you can get from various roms'. Btw, clicker is used to calibrate the keyboard so you don't have to install it.
NJAZ, what's the result on using CM6.1 without SetCPU? Big difference or not?

Actually, by process of elimination, the kernel was the issue. I remember hearing about there being a bug in the older dumfuq kernels with something idle being null, I really don't remember but it had something to do with sleeping. I flashed pure CR_mod and then 3.5 dumfuq and I experienced the same issue where it wouldn't sleep. I flashed 4.0, but I think it's too soon to determine whether or not the same issue with sleep is occurring.
I tried doing what you said with LatinIME.apk, I even imported the lib file from /system/lib on CM6.1, but the it was nowhere to be found in the system when I booted. It wasn't under keyboard settings, and HTC_IME was gone. I figured it was an incompatibility between froyo and eclair, since the stock sense rom is eclair and the LatinIME.apk is from a froyo ROM. Do I have to something more than just adb push the apk and lib file? I also tried installing it with a file manager, and no surprise, problem parsing the package. It's a system apk so I didnt expect it to be able to install via a file manager. Do I have to use adb install instead of adb push? I'm wondering if htc IME is so wired into the system that it won't work that way. What if I rename LatinIME.apk to htcime.apk or whatever the name of HTCime is and see if that works, because the system may be is treating that as the stock android keyboard, rather than a third party one, because it is labeled touch input in settings, just like LatinIME in aosp roms.
I'll experiment some more I guess
edit: Nevermind, 4.0 is draining as well, albeit less rapidly. Ah well. I guess I'll have to go back to CM6.1 if I want to do overclock. Shame, I love sense so much.
ANOTHER edit: nevermind, you were right, it isn't the kernel at all. It happens when I turn wifi off. I'm assuming that's because I don't have a data plan so it's continually retrying a server that it can't access. I don't know why it didn't do this on the stock HTC kernel, but I'm pretty sure it's the issue. If I turn wifi AND mobile data connection off, it stays at normal drain as well. Well, I'm at 11% and my battery app is estimating roughly 1 hour and 20 minutes remaining, so I don't know if that's GOOD, but I'll give it a good full charge tonight and run it tomorrow. I hopefully will have data activated tomorrow so I can really test it.

Hey guys new to the slide forum but not new to the site. I come from the G1 thread and we had the similar problem. How is your battery life on a 2.1 ROM? I have my phone rooted with a Sense ROM and it has 2.2 and i do see a bad battery drain as well. I remember froyo ROMs battery life may not be the greatest yet. I remember that was always a big problem over there and it looks like it still hurts here. Have you tried setcpu settings?

Maybe this information will help, i forgot to mention last time i posted that i'm not using a HTC device, i'm using Samsung Galaxy S, and there are more ppl with this problem on our forum aswell, so maybe someone can use this information correctly, i mean, it's either a program that's doing this or some strange freaky froyo process that not everybody has? or idk..

We'll need to get a log or something from one of the phones doing this and see if we can pinpoint the issue. Anyone experiencing this issue using compcache? Maybe it's doing some sort of background compression/decompression or swap is swapping too much while the phone is 'off'. Like I said, we'll need a log dump uploaded so we can sift through it.
As far as the latin_ime, try getting the one from a 2.1 vanilla rom. Check the slide rom bible for the 'senseless' roms like CM5 or something. That should do it.

Well my desire was to get the froyo latinIME onto eclair, since it's prediction engine was so much improved, but I'm getting used to HTC_IME so it doesn't matter.
As for the battery, for me at least, running the cmkernel from dumfuq, v4.0, I get BETTER battery life than the stock HTC kernel. Weird right? If I enable data I get tons of blue in spare parts, under network usage, for things like calendar and contacts. I'll have to assume that's because of the lack of data plan, my data plan doesn't become effective until december 9th. Otherwise, I have no excessive drain. It must be a cm6 issue, with cell polling. Cell standby was always up in the 70%+ range in battery usage in cm6, and on the stock rom it's around 27%. Wi-fi and display are highest, and I still get 20-25 hours.
I agree, to pinpoint the cause of the problem in cm6, someone needs a log to analyze, I'm not actually that smart with these things, nor am I running cm anymore, so can't really help there, but it'd be a good start.

Well I just recently saw this almost exact same issue (maybe not as extreme) on the samsung tablet running Cyanogen. They removed the phone, telephony, mms, and one more .apk to resolve it. This issue was caused by the lack of a use for those .apks but the system was still using them... a lot. It seemed similar but not exact, maybe some of us more tech savvy people can look into those and see if there's an issue.

Yeah that'd be cool. It must have something to do with that, since it's the cell radio sucking battery.

I flashed 6.1.0 stable, battery drain seems to be slightly less. I'm still at around 5 or 10% below where I was at this time on stock, with 9.5 hours off the charger, current level 57%. Although, I did use airplane mode for almost 2 hours, so really I'm like 10 or 20% below where I should be. I just can't figure it out, cell standby is at like 80% usage in this ROM. It's ridiculous, is it the polling intervals or something? How can it be so much less battery efficient than stock?

I flashed 6.1 RC2 with a low battery and had trouble with battery life. TMO's service was acting very strange for a couple of weeks and my cell standby was consuming a lot of juice. Flashed 6.1 RC3 with a well conditioned full battery. At first I used no setCPU just to see how things would go ... 11 hours from full battery to empty. Added setCPU to RC3 and got 27+ hours out of a full charge. Either TMO fixed it's towers or RC3 was better with cell standby because my network usage was not cranking overtime like it had been. Finally, I flashed 6.1 stable with setCPU and I average around 22 to 24 hours on one charge.
One observsation - when I first flashed RC2 I was really into my phone again. I was constantly tweaking it and flipping through options, testing apps, digging new Gapps, etc. ... bottom line I was just using my device waaaaay more than usual and I think that played a huge role in my (supposed) poor battery performance. All seems to be well with 6.1 stable.

[Q] HTC Kaiser CPU Doesn't Sleep?

Did a search, and didn't find anything regarding this, so I'll point this out. I've noticed whenever my Kaiser (KAIS100) goes to sleep, it doesn't actually sleep, I can still press every button and the phone will "wake", screen comes on.
When I check Spare Parts > Battery History, it shows my phone's been running for 5days even though it's been on for 10 minutes actual. If I continue to put the phone to sleep that time grows exponentially.
Is my KAIS really sleeping, or is there a bug somewhere?
I'm running l1q1d's latest .32 kernel, with Fat Free Froyo build with system/data on NAND.
Battery also only lasts about 8hrs in "standby", and not even 2hrs with full use. With WinMo, I get about 36hrs standby, and about 5hrs full use.

Have you modified .nbh file with atools and entered the correct value on the advanced batt capacity? (units = battery real mAh * 1.6) if you havent or if you own an old battery you'll experience a lot of batt consumption or inaccurate readings....

The phone locks like it's suppose too, but the problem I'm having is the CPU of the Kaiser isn't actually falling asleep. I'm getting the same battery consumption as when the screen is off compared to on, and sitting there (no activity on my part, just leaving the screen on for no reason )
Every so often the phone will be asleep, and the only way to bring it back on is by hitting the power button, but about 95% of the time I can press the call button, end button, OK button, IE button, hell even push down on the wheel on the other side of the Kaiser and the screen will come on showing the lock screen.
As far as the battery capacity, I have not done that, but the phone's been auto-learning my capacity, and it will get to the 2160 units, compared to the 2000 it's always set too, and sometimes reach 2377 units.
I have tried several Radio versions, down to 1.65.xx.xx version (which was the original version on my phone), and no changes, and tried different builds and no change either. DZOs kernel doesn't make a difference either, except screw up my battery meter completely. lol

uhm thats wierd.. i can only unlock through the power button, what i have experienced is that if its conected to an external power source it does reacts to any button I press.... but not on battery... maybe its a build issue... right now im using scoots CM rls 5a, dont remember if warbyte's donut behave like that...

Did some more testing, and found that without it plugged into power it does only respond to the power button, but again it's only about 15-20% of the time, and even those times seem iffy as it just seems like the phone's just slow to respond.
Phone is also somewhat warm as well even when "off", and I do have the phone overclocked to 450MHz, kernel is set to 425 (running a test on speed/stability atm)
At 425MHz it's still reasonably warm, and at 450 the temperature jumps alot.
Anyone else have an issue of the tap sounds when tapping on the screen sometimes not playing? Granted phone quality is great, and GPS is working well, though Camera is broken on my end, even though it was working before.

It sounds like there is a real issue. Some application is running continuously for you, preventing the CPU from going to sleep. I have had that before. Try removing widgets from the main screen. For me, the problem was an app that showed a flip-clock and the weather, and looked just like HTC Sense. I don't remember its name but it used to be popular.
The newest 2.6.32 kernel seems to sleep relatively well for me. Sometimes it wakes on any key, and sometimes it wakes up to a totally white screen. Other times it just plain refuses to wake up. Usually I can coax it back to sanity (from white screen or from sleep) by Fn-Left keyboard softkey, then Fn-Right keyboard softkey.
Your phone should get approx 10 or so hours of life from a charged battery. Less than you get with WinMo, but lots more than you seem to be seeing.

Ok, I'll give it a whirl, and remove some of the widgets I have running, and see if it does help out. Right now though I'm re-installing /system as I tried messing around with the density as 110 seems to work real well with where things are placed on the home screen (no widgets are overlapping each other), but Market won't work, and the Android Keyboard keeps crashing (on-screen).
But anyways, phone's booting back up, so I'll test out the battery life here again, as I got about 95% charge right now, so should serve as a good test for battery life, and CPU Sleepage.

Having a similar issue, seems to behave ok (screen lock comes on when I press power button) but power usage on standby is similar to original poster's. About 8 hours standby. Went to bed last night and it said 66% charged (1300mAH battery) and it didn't last the night. Takes a looooong time to charge to full though so I doubt it's lying about fully charging the battery, suggesting it's using it up at a fast rate.
How do I check background tasks?
Edit: This is with WiFi, GPS and Sync OFF by the way. On the other hand I live in a low signal area (typically 1-2 bars) could it be straining to get a better signal? Used to have an old nokia that used to run itself flat in no time when there was a low/missing signal!
Edit 2 : Figured it out, turns out the ebay app has a service and a process running - even with notifications turned off! Have killed these and see if anything improves

That could very well be part of the problem, although it shouldn't kill it from 66% with just the radio. How much capacity does it calibrate itself to?

Phone Radio really shouldn't use more power with low signal, in fact it really shouldn't affect power output at all (well except the fact that it's on). I have a 1350mAH battery, but it's reading at 2470 adjusted, so I re-flashed a new kernel with the new battery changes, now it's reading 2437units adjusted, which is over 1500mAH for the battery which is not what I own. But on the bright side, my battery capabilities are improving, and the battery meter is starting to read alittle more accurately.

yes, i boutght seidio 1600 mAh, and the kernel ended up adjusting it to 3260 units... (about 2000 mAh) maybe the 1.6 factor isnt right just as n2rjt said, maybe its closer to the 2.0

Seems like ebay may have been the culprit. Killed the ebay process and application in the background and only used about 10% over night (as opposed to over 60% the night before). I'll have to leave it overnight with ebay running again for a proper scientific test next

Yah, I'm starting to run into issues with certain apps keeping the phone awake and not letting it sleep. I kill some of the apps and it actually helps out the battery some.
I installed the original launcher from one of the other froyo builds, but came across with an FC with acore, so now back with ADW.Launcher or LauncherPro.

When you install a app, take a look at its requirements, like "PREVENT FROM SLEEP". You might have a app doing just that..

Yep, most of the apps I download have that. But in sad news, I'm actually going back to WMO 6.5 as I can't seem to keep Android stable on my kaiser.. I've reinstall the same build twice (which I know is not corrupted, as it was working fine 2 days ago), and Market is always corrupted...... So, for now, until I have a secondary phone I can revert too, I'll be going back to WMO for the time being.

LOL! Not like I'm leaving, I'll be popping on here every so often, and still doesn't mean I'll use Haret to load up Android to test out new builds that come out, and new kernels that are released in the future.

[Q] Batery life and where to instal android

Hello.
I've just installed android on my HTC Tytn II (Not so Super Froyo Release).
It is very nice but the battery life is very short. I don't think that i can manage for one day without recharging. I think a couple of hours just. Is there something i can do to improve this? When i entered the #*#*4636*#*# it says that the android system is the one that keeps the processor running when in stand by. what can i do?
And another question. How is it better to install. On nand system and data? For now, i've installed data on external data.img. But there is not much room for aplications. Is it better if i install data on sd partition? And if so....how do i do that?

If the processor is still running while in standby then that means you have a widget or program running that's preventing the phone from going to sleep. When you install an app in Android always look for "Prevents Phone from Sleeping" where the app installer says what the app requires to access.
Also, as I have said in the help thread, there is nothing you can do about the battery life. It's Kernel related and being investigated, so until that time unfortunately battery life is very short because the phone's CPU while not in standby runs at 100% speed, unlike all other android phones which decrease their CPU speed and voltage when they are idle (sitting at the home screen or even checking emails).
Also, if you are installing into a data.img file on your SD Card, you should have about 256MB of usable space in /data, if you are running out of space with just a few applications, then you are still installing on NAND, as it only has about 90-100MB available depending on how you have your NAND partitioned, please verify that you have fstab set correctly in atools and re-flash your firmware so that it reads the /data partition under data.img instead of NAND p3.
BEst thing to do if you are wanting to install /data on SD Card (or data.img), is have /system on your NAND for best performance when Android is loading from boot. For quick performance, you should have /data and /system on NAND. For more space and stability, go with /system on NAND and /data on either SD Card partition or data.img.

Thank you for the answer.
I have another problem...when i'm recharging the phone...it says that it is fully charged at 90%.

That means there is a incorrect battery calibration number in the kernel. Run atools and check under Battery Settings > Advanced Settings. If you have a 1350mAH battery (noted on the battery itself), input 2160 units.
If you have any other type of battery, take that battery's mAH and multiply it by 1.6 to get the battery units. If the battery continues to stop at 90% after making that change, and the battery is old, then the battery may be losing it's charge and can only sustain up to 90% of it's core charge.

Thank you. now i'm trying with 2160 set in atools. i will inform you if something is wrong
Another question. How can i see the battery status in %?

i think now it's ok. but still the battery life is very short. and somethig is keeping the android from sleeping but i don't know what. when i enter in the *#*#4636#*#* it says that the "android system" is the one that prevents from sleeping.
And another question. What is the difference between panels. If i am installing with panel 1 the screen looks very bad. Now i've installed with panel 3 but i don't see any difference from panel 2. It is ok that i've installed with panel 3 or should i use panel 2?

I need to know how you set your phone up, including kernel, system/data partitions, which build you used, what radio you're using, anything that could help me investigate further.
I have 2 AT&T Tilt phones, one for daily use and the other for testing purposes only. (nice to have friends with connections, I got them both for free).
My current "daily use" phone will use about 1/2 battery per day with moderate use (texting/Pandora/phone calls) and will last 3 1/2 days if I just let it sit in standby. 3G is enabled and I use Rogue Tools to O/C to 480. I get almost no FC errors and everything works as it should. (The only FC I get is with ADW, which I press "wait" and it comes right back). I was able to set up my phone on the wireless domain at work and ported my work email to it.
Again, I would need to know what you're running as it sounds like your phone is not actually "sleeping" when it should.

So...the radio is 1.70.09.1 or something like that, the latest 2.6.32 kernel. android build is valentine. I am using system on NAND and data on data.img. now i can use the phone for a full day of use but i have other problems. when i charge the phone it freeze and white screen appears. Usually i left for charge at night so in the morning i find it with white screen.
Can u please tell me what are you using so i can use to?

[Q] More info on the Android OS bug. Suspend process , wakelocks and battery life.

Hello all,
I first posted this in Q&A on the home forum. There doesn't seem to be any interest so I thought I'd post it here again. Below is what I wrote on the original post.
"If you’ve been supremely annoyed with the AOS bug like I have , here’s some interesting information I’ve found (Did a search and it appears no one else has found this yet). It’s a paper written (in 2010)by Rafael J. Wysocki which touches deep into the subject. What I hope is that it will help some developers understand this bug and ultimately integrate a work around / fix as soon as possible. Hopefully this will help some users understand what is going on with their phones as well.
I have and Epic 4g Touch and all the ROMS I’ve tried have this bug but according to the article, looks like a kernel problem. My suspend / events/0 processes runs for a long time, eating up cpu and I don’t have it as bad as some people but thought it's worth mentioning.
Basically what I get from the paper is that…
1. The suspend (and by association the events/0 process) process is Google’s implementation of a power management system, an add on to the Linux Kernel
2. That the wakelock / suspend feature is , to make a long story short , not working the way it’s supposed to.
3. “Poorly” written apps, or apps that are written without the inner workings of how suspend /wakelocks work, will trigger this bug. This can be ANYTHING.
4. Supposedly, kernel version 2.6.37 will fix this. The Epic 4g Touch kernels are all .35 as far as I know which explains the fact that so many Epic 4g Touch owners complain about this.
Would love for the smarter than me people to give their take on this?
Since this is my first post, it won't let me post a link. Do a google search for Rafael Wysocki suspend_blockers.pdf and it should be the first link that shows up."
Hopefully there's more interest here!

Danial, thanks for the reply. Not sure if it was intentional but that's not the document I was referring to. However it looks like useful info and simplifies some of the explanations and even uses the the document written by Wysocki as a reference so thanks for that.

Bump! for battery life lovers!!!

how do I check to see if this bug is causing battery drain on my phone. thanks!

If you go to Settings, About Phone, Battery usage, you'll see "Android OS" take an unusal amount of battery time. Mine varies from 25-80%, some others I've read, consistently get 80%. You should be running on battery for a while before you check this since if you've only been on battery for a few hours, that stats may be misleading.
A more precise way is also to download the free Battery monitor Widget, and in the statistics section, you'll see the processes "suspend" and "events/0" take hours of usage when it shouldn't. You also may see *wakelock* take up hours of time.
Some dwho have it bad, download watchdog, and monitor on the fly, which processes go over a certain amount of % usage. If your batter drains quickly, suggest this route to confirm its suspend and events/0.

thanks for all those great infos. my android os is usually under 10 percent after several hours of use so I don't think that is buggin me. Could you explain exactly what a wakelock is? I know I could use the search button but the info you provide here in this thread might help a lot of other people trying to resolve battery drainage issues. Thanks!

I'm assuming you were talking about this site, which was the second search result:
http://lwn.net/images/pdf/suspend_blockers.pdf
As a side note, my Android OS is at 7% of my battery usage right now.

May I ask,
1. How long your phone is on battery for?
2. Kernel Version?
3. ROM?
Would love to be @ 7% for Android OS!

1. How long on battery 1:15
2. Kernel Version EL29
3. ROM StrongSteve blue, Odex
4. Android OS 3%
I will let you know what the OS % is at the end of the day before the battery dies ......

A wakelock is, as I understand it, a process in the Android kernel that temporarily tells the Android device to hold off sleeping (stop the suspend process).
This allows for a process , application or device (such as your wi fi antenna) to turn back on and do what it needs to do. The suspend process is suppose to tell the phone to go back to sleep but with this bug, either or can get stuck and therefore use up more cpu that it's supposed to.

Interesting, I'm on EL29, have used Strong Steve's ROM but it still persists for me. Next thing I will try is to install Steve's ROM only, no additional apps.
I've gotten 2 days , 9 hours battery life (on light use, about 3 hours screen time, lowest setting) my last round but I've Juice Defender configured it to heck and undervolted as well. I think if I figure out what app may be contributing to this I just may get 3 days, may be 4 days battery life.
thanks for the info!

Not a great day for battery stats but i did change my modem from ek02 to el29 last night trying to solve a gmail keeps sending issue i am having. Last time i was on el29 it seemed to consume more juice so i switched back to eko2.

So i have system updates always running. When I go to try and update PRL and firmware etc, it gives me an error. I assume I need to re-flash a stock ROM, then update? I wonder if my problem is this: My used my phone for a few weeks, then ported over a new number. Under phone info, it still shows the original number. It uses the original number for a hotspot confirmation. But my phone clearly has a new number. Is this need for the phone to update causing the battery drain?

PRL's (and profiles) should update despite having a custom ROM. Firmware won't however.
I think it's unlikely that the fact you can't update is causing a battery drain. To be sure, you need to find out which process the phone uses to do updates and see if they are taking up alot of CPU (OS monitor or battery monitor widget will help you with CPU usage.)
I think you simply have the OS bug like the rest of us.

Yeah your battery life is dismal but the Android OS percentage is not nearly what I would expect it to be if the bug was causing this.
I would at least try a free battery saving app if you haven't already. You could probably get a few extra hours out of it.
Might want to turn 4g off also and see how much more mattery life you get.

Battery Drain In use (yes i know this sounds dumb)

I´ll cut right to the chase: I bought an lg g3 used, so far loving the device but I´m getting intense battery drainage when phone is in use. It´s a d855, fulmics 5.3 and xceed kernel underclocked at 1.5. I also have greenify, powernap, naptime and amplify installed and configured so stand-by time is great, if not awesome! My only issue is this: as soon as i start using the device (listening to spotify, browsing, texting etc, i can literally see the 1% dropping almost by the minute! I only manage 1-2hours SOT and i have BBS & Gsam installed, both don´t seem to show ANYTHING out of the ordinary, i can post screenshots if necessary but i honestly don´t see anything wrong... On occasion if device is rebooted 2-3 times in a row it might lose up to 40% in one go and then just hang there for a while so as to catch up... Despite this phone charging really quickly, it is not enough. I should be able to hold at least a semi-decent charge right?! Also occasionally if in standby for an extended period the batrry gauge might go up by up to 6%.. I live in finland so getting a new battery might be a bit of an issue (really expensive, if i can even find it) Unplugged today at 7:40 amd now at 12:24 I have 44% left with minimal browsing, no games just texting and listening to Spotify (downloaded playlist, not non-stop maybe 45min). I should note that I bought this phone used and it used to have random reboots until rooting and custom rom with everything set up, no more random reboots really... Could this still be a battery issue even though all apps show that battery health is good?

If your device is rooted, one way to get information would be to open a terminal window, (requires BusyBox) and enter the command "top". This runs the 'top' utility which gives real-time data regarding system load. While running the utility, there are single letter commands available to sort the display list of processes in different orders such as by highest load. At the top of the display is a summary of data, one of which is total system load. A high number near 100% would be abnormal except for very short period of time. If it stays up near 100%, then you can start looking deeper to find out what the problem process might be.
Most likely, you just have a battery that is near end of its life cycle.

If ur using xceed kernel dont use xposed and battery saving apps its already mentioned by kari zeroblade the dev ...also u need to use the 4v beta version of the kernel for MM which is the latest not mentioned on his site check the thread ...also try replacing the stock battery..n try going back to stock as well
