Battery Leak - Help Appreciated

Hi all.
I'm experiencing some sort of battery leak, but nothing is jumping out at me. Went to bed ~ 95% and woke up to ~ 20%.
Battery Use Stats:
Cell Standby - 44% (TWS - 0%)
Phone Idle - 45%
Voice Calls - 6%
Display - 3%
Dialer - 2%
Here is the software info:
Firmware - 2.1 Fresh Toast
Baseband - 2.42.00.03.10
PRI - 1.70_003
PRL - 60664
Running OC Widget on detect settings & autokiller on aggressive.
Using SpareParts - Partial Wake Usage - Calendar has the largest bar above Android System (yet I really don't use the calendar for appointments).
Any thoughts/tips/tricks would be much appreciated.
Thanks!
Jerry

I'm assuming you have reboot the phone?
In addition, on your OC widget what your setting for screen on and screen off?
I'm still playing with setting that best for me and the phone. However, this is my current setting for OC widget: for screen on 729600 for min and Max and screen off 245760 for min and max. I saw if I did't select differ freq for screen off, the CPU was run at same speed at screen on. Compare the 2.1.1 I'm getting average 8-10 hr of battery. I'm guessing OC might drain battery faster. Maybe I'm wrong.

Yes, I have rebooted since loading. I used the auto-detect settings for the OC Widget, but I guess that could be an issue. 8-10 hours of battery seems low to me? I was getting near 24hrs average (some higher, some lower) on Fresh 2.0d.
Here are the settings:
OC Widget Settings:
Screen On - 245760,384000
Screen Off - 245760,384000
I guess that could be an issue.

What's your awake perentage at?

Strange I have mine set higher than your for screen on.
Still battery hr for me. I know 2.1.1 I was getting at least a day an half with moderate use.
Like abcdfv said what your awake and uptime?

Up time: 20:35
Awake time: 5:57

Awake time looks good.
Try this setting on your OC widget:
480000 min and 576000 max. It may or may not help.

Thanks for all of your help.
Would this be for both screen on & off?

Screen on.
For screen off I have mine set at 245760 for min and max. So far battery life is OK. Since unplug at 7:45 AM (100%) and now it at 66%. Few calls, web surfing and facebook. Roughly 1 hr 20 mins usage of phone and 4hr 30 mins standby. I know compare to 2.1.1 it not great battery life.

Thanks - I'll try that.
So far, I might head back to Fresh 2.1.1 if this battery life stays like it is running Fresh Toast.

You could also try running RegawMod, I have had noting but good to say about the ROM so far and battery life is wonderful! I use Strict I think on ak though., stay around 60MB free ram if that helps at all.

Thanks for the help. I decided to factory wipe, wipe SD and cache. I then flashed Fresh 2.1.1 and my battery life is back to normal. Might play with Fresh Toast some more later.
Thanks for all of your help.

Battery usage has never lasted a full day

So as the title says, my note has never lasted a full day on a full charge. Even with moderate use, it lasts maybe 15-16 hours. With heavy use, playing a game or 2 or using the browser, it lasts maybe 9 hours. From the first day I got it I've rooted it and have used only the romow rom.
Currently on the version 7.5 HD.
BB: LA4
Kernal: AbyssNote 3.3
Each time I flash a new rom I always do a battery calibration test and even wipe the battery stats on recovery.
I notice people get a full day's use from the battery and maybe even more. Is there something I am missing? My wi-fi is always off unless I am at home or when needed. I turn the data connection off too most of the times. When I look at the battery usage in settings (I do this often), the display shows the most usage, always more than 65%, and nothing else. The android system, android OS, cell standby and whatever else are always less than 10%. Is there something I can do to increase the time the battery lasts? I'd like to get a full day's worth, and even more

Use black backgrounds and dark apps? Amoleds don't use power to display black. Whites will suck your battery dry.

Recently i visited a samsung service centre. I asked the engineer as what kind of problems people have reported in the note other than screen issues and he said battery issues and people ve got their batteries replaced. Maybe u want to get urs checked.

I would also suggest get your battery checked. But more than likely, Samsung will say 15-16 hours of moderate use is normal.
I am currently using Rocket ROM v20 with Abyss 3.5b. I have had it without charge for 12 hours now and from 100% it is at 82% right now. So far today I have watch an ep of anime (22mins long), gaming for 1.5 hours, had 4 phone calls (total of 42 mins). I think only draining 18% after all of that is impressive.

That is impressive. If I watch a 40 min show only, my battery would go down from 100% to 65. And if I play a game for an hour (depends on the cpu/ram usage the game takes up to), then my battery is at 20%. And this has been since the beginning. The moderate use I am talking about is calls here and there, texting, playing a game for maybe 20 min. Like today I played Shadowgun for a total of an hour, where's my water for 20 min, and texted a bit, made 2 calls, and used dolphin browser for 10 min. It hasnt even been 12 hours and my battery is at 20%. Ahhh I think I just need to get a new battery.
I know roms/kernals/basebands all factor into battery usage as well, so are there any suggestions as to which one might be good with this? Aesthetically I love romow's rom. I love every layout of it. Rocket rom is a little too "in your face" kind of, atleast for me.

Im always set my brightness to 0% and im not using auto brightness. What if you change the kernel to FM 2.0 Kernel. i find it saves more batt than abyss kernel.

I actually like the "in your face" look, of course that is my preference. I heard that checkrom is good for battery but in all honesty, I have tried a couple of roms and there isn't a huge difference between them. The biggest difference with battery usage I have notice is when you start using a OCing app with profiles like SetCPU. Tweak the power usage with each speed step and create profiles for when the screen is off, on call and etc.

How hot does it get compared to room temp? 15C warmer? 20C warmer?
I'd really love to work with some people to come up with a step by step guide on how to track down and fix battery drain / over heat problems.
The best way to waste power is to make heat with radio chip and GPU. Second best is to make light with torch or screen.

I know with the change in battery technology, some old practice no longer applies but I still follow the old rule of thumb when I get a new equipment.
When I got my Note, the very first thing I did was charge the phone for 12 hours before actually using it. You might want to give that a shot, the reading on the battery may not always be correct.

may i know which governor are you using? try to update the AbyssNote kernel to latest v3.5c and try either the AbyssPlug, lulzactive or SmartassV2 governor then see if there's any difference

Running stock LA4 ROM here. Brightness usually on lowest. If you don't touch the phone, it can last on standby a week. See below how it only lost 3% after 17 hours. Of course as the screen was off all the time, the internal processes take most of the power consumed.
After more than 1 day I still have 50% battery. See how it drops fast when I'm using the phone to read and download web pages.

I have the self same issue - battery hardly lasts a day - I just about manage to get home 8 hours later on critical - to hook it up to mains to charge.
All I use it during the course of the day - is browsing forums via tapatalk, viewing the occasional email. No hectic media consumption and music playing.
I am trying a different route now - it was running on stock firmware - over the weekend I've taken the following steps.
Rooted my device , installed CheckRom Revo v5 , running speedmod kernel with modem LA4
Hoping to see how that improves things.

First of all, you should post a screen shot of your battery graph.
How bright is your screen? If it's at 100%, then you're going to chew through battery very fast.
Games that require very high cpu usage will kill the battery.
Some games I can play forever on - some games, like Plants vs zombies, or puzzle quest 2, kill the battery. I can probably get 3-4 hours worth on a battery, and that's with a very low screen brightness. That's the price to pay with a fast cpu.
Dolphin is quite the battery hog too. I try to avoid it - I browse for hours with opera mobile, especially with the green on black mod.

I use the ondemand governor usually with overclocked to 1600. The only profile I have set is the temperature over-heat (temperature above 104 F, 40.3 C) and i've set it to conservative with max cpu to 1200. What should I set the screen off and in call frequency to be? I have just updated to AbyssNote 3.5 and changed the governor to AbyssPlug. Lets see how it pans out tm
My voltage settings are:
1704 MHz - 1375
1664 MHz - 1350
1600 MHz - 1325
1400 MHz - 1300
1200 MHz - 1250

800 - 1000

Whats the best app for battery statistics? I will get the graph and post a screenshot tm. My brightness is usually 50 % set in the middle always. Today I put my brightness all the way down to 0, I literally did not use my phone, maybe turned it on couple times during the day for 2 min, sent 1 text, played a game for 5 min, and used a medical application for 10 min, just to check the battery. With that much minimal amount of phone usage, after about 9 hours my battery was at 79%. Is that normal?
Just wanted to say thanks for the help also

it should make a difference. for battery monitoring, I'm using Battery Monitor widget. you may give it a try.

Install better battery stats and check for kernel wakelocks. If there exists some that last longer than 10 mins then some app is involved in the battery leak

[Q] 1% Batteryconsumption per two minutes normal?

Hey guys,
I just wondered if you guys have the same problem that you lose 1% battery every 2 minutes when you´re having your display on. I know it´s quite known that big screens suck the battery like a vampire but that´s just odd, because I don´t even have to do anything with the phone just staring at the activated display.
I´ve had these troubles from the beginning with FW 10G then updatet to 10H and did factory reset- nothing changed. I tried different brightness levels without any differences in battery consumption, which is totally uncommon. And the freaky thing is there is no difference whether I have airplanemod on, wifi turned off and so on. It is always the same... Although when the display is off there is as good as no consumption but really 1% battery per 2 minutes that´s just sick. I can´t believe it.
Now i wondered if this is normal or if I should turn it to the customers service to check it.
Please tell me if you explored the same things with your LG 4X HD

Well i found it odd too but if you would root the phone and install something like setcpu you would actually see
Min CPU Freq --------------- 1.5 GHz
Max CPU Freq -------------- 1.5 Ghz
Er yeah .... after saying that i think you know why its using the battery so fast. I rooted my brothers phone and changed the clockspeeds , but no matter how low i set the min freq on "no frills cpu control" it always shows on the toast message 750 Mhz or somewhere around that.

Well thank you... I´ve rooted it and thought it had something to do with apps running in the background but it didn´t help at all so I thought this can´t be, mine must be wrong somehow.
Especially because i haven´t heard anything in reviews or forums about this rapid battery drain. This is something I´m wondering most, how can a phone taking so much battery be rated so high It sucked 3% watching a 3 minute video on youtube...
I won´t think I´m going to be happy with this phone and the best is when I contacted customers service later today they told me to send it in because its not normal, but now that you said the cpu is set this high no matter what, I can just suggest they don´t know anything about their phones...
Bet the only reward I get sending it in is "all is fine our phone likes to suck your battery, so what? Just keep the display off"

Screen off "deep sleep" battery drain is quite bad too ..

[Q] Which Governor/s to deal with heat

Hello,
A friend of mine is using the phone for facebook/whatsapp only and he really hates the heat from the phone
I guess those apps don't need the CPU to be at max freq so my question is:
Which Governor / Cpuquiet Governor to provide the least heat and an a reasonable performance for those apps?

Interactive or ondemand governor and lowering max frequency to 860 MHz should extend battery life and reduce heating while keeping the phone running smooth in those apps. For gaming turn back to original frequency.
Alternatively, min frequency to 860 MHz and powersave governor, but the first option is better, I think.

Thanks for your reply I set the max CPU to 910 but I don't know what to use out of the three governors:"abssplug , interactive , ondemand"

I set the max CPU to 910 but I don't know what to use from those three governors: "abyssplug, interactive, ondemand"

I don't know the first. Interactive and ondemand are working similarly - they reduce frequency when max isn't needed, to extend battery. I recommend you to use one of them.

Hi Community
I have installed last stable (3.1 from 3.07.2014) version of LiquidSmooth and Mourty's kernel 3.1.10. I would be extremely happy, because I have never seen this phone working so smooth and fast, however I have two major problems:
- can't change preferred network option, there is only 3G to choose, I actually need 2G. May that be operator's (O2 in UK) fault?
- second problem is even bigger. It takes 9 hours to discharge 100% battery to 0 when I'm not using the phone at all (0 calls, 0 texts, 0 wifi, no gps... just laying on the table with everything switched off). On the CM or stock ROM I had completely normal battery life.
My settings:
CPU speed: 51000 - 1150000
Governor abyssplug
Cpuquiet Governor balanced

Please I really need your help as at the moment phone disconnected from the charger becomes useless...

Ondemand- when in idle the phone is on the lowest frequency. When in use, it is at the max frequency.
Interactive- is a scaling governor that scales the CPU frequency based on the load. Its possible that this will allow the CPU to stay at lower frequency with screen on thereby saving a little battery.
Abyssplug- is a hotplugging governor that scales the CPU frequency AND number of cores active based on the load.
I suggest using abyssplug with the "balanced" CPU_Quiet governor (CPU_Quiet determines how many cores are active at any given time) to save battery.
To reduce heat, you can underclock your CPU to 1.3ghz and undervolt your CPU based on your CPU variant. Also I've noticed that replacing the crappy lg battery also reduced heat since the lg battery is covered in plastic and does not dissipate heat very well
Also what kernel are you on?

Thanks for answers mates. Right now battery draining when phone should be in deep sleep is 10% per hour. over 70% of that is used by kernel, however I have reinstalled kernel yesterday and it didn't help at all. The strange thing is that when the phone is switch to plane mode it doesn't drain energy at all, 1% per few hours. I would understand that if the draining would be described as searching for GSM singal, but it's not, that's another 28% of battery usage. So there is definitely something wrong with gsm signal.

hi
I have also that phone and i am not happy. Why is very hot. And also the battery is crap. Is logic for battery do not take long time, because the heat it means energy . Its caloric energy you lose. I want to try to lower the frecvency of cpu to 1000 . But ... Its like i have an MERCEDES car and the engine is not good( low power and higher consumption on 100 km). I am not recomand that phone. The chinesse phone for ex with mtk cpu is more good. It is a fix for this? I see here in the forum a guy who put siliconic vasseline on cpu. Maybe a cooler , like on the pc . Shame of you lg. My friend have the same phone and like mine have the same problem with heat and also the left corner of display is unglue i think because of heat. If you put the phone in light and look not straight , in upper corner its like on samsung s3 phones for ex , when the special gel between display and touch is damage. You have a problem like this with the display?

I have also that phone and i am not happy. Why is very hot. And also the battery is crap. Is logic for battery do not take long time, because the heat it means energy . Its caloric energy you lose. I want to try to lower the frecvency of cpu to 1000 . But ... Its like i have an MERCEDES car and the engine is not good( low power and higher consumption on 100 km). I am not recomand that phone. The chinesse phone for ex with mtk cpu is more good. It is a fix for this? I see here in the forum a guy who put siliconic vasseline on cpu. Maybe a cooler , like on the pc . Shame of you lg. My friend have the same phone and like mine have the same problem with heat and also the left corner of display is unglue i think because of heat.

That's what I felt about it before I undervolted CPU by -135 mV and LP cores by -75 mV, underclocked to 1300 mhz.
The technology this chipset uses is the problem here.LG did a fine job with keeping phone cool in stock kernel, though stock performance is not compareable with custom ROM/kernels as customized ones have better performance.1300 mhz is fine though, unless you play heavy games such as real racing 3 with many bots around, you won't feel the difference between 1300 mhz and 1500 mhz.

I see what is the problem with my phone with temperature. First i want to tell you about someone on forum who open the phone and see how the producer (LG) make the cooling. On the motherboard in the cpu zone it is a metalic sponge who make the transfer of the temperature with the metalic plate inside the phone. It is the same plate you see on the back when you take the battery. So, in his case and mine the problem is this sponge dont make very good connections with the metallic plate. WHy? Because ( in my case) , the lcd in the top is not glue very good, the tape double adesive is open. I think in time because of heating , the tape is opened. What do you must to do? If you can not make , put someone who repair the phone .So, you must to put some termal paste like pc cpu , or put a small aluminium plate, between cpu and the big plate inside the phone. That it. Ony if you have problem with the temperature like me. For ex . yesterday , without termal paste my cputemp it was max 60 degrese. Now , after modification i have i game and cpu stress app max 39 degrese. I am very happy now, but i must to rezolve also the problem with the bettery drainage. Maibe i must to change the battery. If you want to speak and put answers you found me on facebook cgamberea , or [email protected]. Sorry for my english, i am from Romania.

Temperature, Time of loading and unloading of the Gt-i9295

Hello, I am opening this thread since I read that some people experience problems with high temperatures or problems in loading and unloading the battery so I ask you to please share your usage statistics to check the normal statistics of our device.
Approximate charging time from 0% to 100% =
Approximate time of download in navigation, YouTube or chrome in mobile networks =
Normal temperatures in sets =
Normal temperatures in Internet browsing and normal use in mobile networks =
Normal cpu temperature in normal use =
And if possible specify the rom and bootloader you are using.
I am one of those who are experiencing problems so I want to know if it is normal or not, I expect their answers.
(Text translated by google)

yes its normal I have S4 Active for 4 years
and Installed many Rom
I think snapdragon 600 is the problem and gets hot very easily with normal internet use no matter how you change the settings
but I have two battery and they wont get hot when charging even with 2000 mah charger
___ by the way I use some cold heatsink when I share my free 4G internet using hotspot
It gets damn Hot downloading 3 Mbit/s
and eat my battery after 45 min
its much better when sharing the internet with usb tethering
and watching youtube .... no way it will burn after 15 minute
but the worst situation for me is hotspot never played a game on my s4 piano tiles long time ago
sorry I have no stats about cpu temp ... right now
Its a nice phone btw I wil use it as long as it works
graet standby time using the latest build from Tsvietkov
