I recently installed the new Kingx Kernel #10 CFS and noticed it had major battery consumption at idle when the screen is off. I would turn off the sync, at setcpu to powersave at 245. In about an hour my battery dropped 10% with absolutely no usage. I noticed this was a problem with King #10 so I switched to King #9 BFS and have the same issue, even when I underclock all the way to 245. My phone lasts about 8 hours with minimum to no usage. What is going on here?
Your phone is probably not sleeping...some apps are known offenders...system panel or maybe default app manager may give you a clue
are you wiping dalvik-cache and cache before you flash?
Uninstall SetCPU and let your processor try to manage power consumption on its own. SetCPU does NOT help with battery life, contrary to popular belief. Do that and report back.
Yes I am wiping cache and dalvik before each flash. I never had a problem with this before. I will try disabling setcpu and see what happens.
Also I believe the phone is sleeping correctly. When I check the awake times and time it from when I turn the screen off, its usually only ahead by a couple of seconds.
check if you have installed tango, that's known to rape your battery

Yeah, they need to include a jar of KY with that download.
So I un-installed SetCPU and my battery consumption went back to normal. I dont get it. I also switched to Kings BFS #9. I have never had problems with SetCPU consuming battery at idle. In fact I could easily get 24 hours usage when I set my phone in powersave mode when not in use. Now it drains battery even in powersave.
Hi guys,
My phone is constantly "awake" despite rarely even turning on the screen.
Would you know what could be causing this?
I'm currently running Caulkins rom and whatever kernel it came with.
My battery life is ~15 hours so I dont think it's affecting my battery too much.
Either way, is there an app that can tell me whats causing the drain?
First of all, to see if your CPU is sleeping properly when the screen is off, download CPU spy… it is an app that gives you total time the CPU has spent in each scaling frequency available.
Then download watchdog, this app tells you which programs are polling the CPU for usage.
Then download “better battery stats”.. this app tells you if there are wakelocks.
With those 3 apps running at the same time, you will find out any abnormalities in your system caused by applications.
Side note – disregard info that either of the apps report about each other (obviously)
Hello guys.
I've made some tests for optimizing the battery and i've decided to share the results. I've also tested an extedend battery 2400mah. This battery needed a calibration which I'll explain here. Everything is free except for an app.
My device and settings are:
Xperia Arc S rooted, Doomkernel v22, Fw.62 GB
Governor smartassV2 1.4Ghz no overclocking
IO Scheduler Noop
I've also undervolted my CPU with -100mV for each frequency
Original Sony battery
You must have root privileges for your device.
I had the same problem with the 1% battery staying for hours with the 2400mha battery but you can solve this with a simple free application you can find on GooglePlay . The aplication name is "Battery calibration". I use the DoomKernel v22 and official android GB 2.3.4. I've made no supplementary kernel modifications for the battery calibration. Read the inside app indication for callibration.
If you have this reading problem with your battery you can use this app.
--------------------------------------------
Now lets start.
I recommend you to install the "CurrentWidget" free widget to see the current discharge rate on your screen and the voltage of the battery.
At approx. 3.5V the battery is completed discharged and the phone shuts down itself. Maximal value is 4.2V meaning the battery is fully charged.
To set up the "CurrentWidget" app, go into settings of the app and set the followings:
Update interval - 5 sec
Display Options - Widget Type -Clear Text
Display Options - Views - select Electric Current (mA) and Voltage (V)
Display Options - Customize - deselect Show last Update time and Show update now button
This widget also shows you when your battery is charging and when is discharging. The thunder sign goes green when charging and white while discharging.
This color detail is very important beacause the battery can show charged 100% but the battery is still charging for reaching the maximum capacity. Test for yourself and see.
Remember this thunder color conditions. You will be surprised.
I've attached a screenshot to see the widgets.
With the CurrentWidget you can easily optimize your android to save battery. I'm also using the free app System Tuner Task Manager Option to see the apps that are consuming Cpu and shut them down if dont needed, or uninstalling them. This is for idle mode.
I've managed to get -80mA -85mA battery drain in aireplane mode with wireless on, phone at idle and the brightness screen at 15%.
Idle means Cpu at 245Mhz and CPU load less than 5%
The -80m value you can see it on your screen if you set up the CurrentWidget widget app.
I've searched for days for such an app and it's perfect for seeing on the screen the battery drain every 5 seconds.
See attached file
I'm also using Temp+Cpu Pro Widget app for seeing the Cpu Frequency and the Cpu Load every 5 sec.
It is not recommended for the above widgets to set the update interval less than 5 sec because it is cpu consuming, resulting in higher battery drain.
With this combination of widgets you can easily find aplications that are battery friendly.
For example I've tested various movie players and there are differecies. For example Vplayer and QQplayer are not battery friendly.
You can test all the apps you use and alternatives to chose the ones that are battery friendly.
If you want , post your battery drain in aireplane mode with wireless on, phone at idle and the brightness screen at 15%.
Maybe we can save more battery.
(sorry for my english)
That's all.
What value do you have after wake up ? I have 2-5 mA. And when screen is on 60-90mA
after wake up I have 0mA even with wireless on but in airplaine mode
Can you also specify the kernel and firmware you use? I've never reached -60mA,
only -69 with wireless of, screen at minimum and in airplaine mode
Please specify the kernel and firmware if you post your results here
i will give this app a try and give u my commends guys
thanks
Morning all, playing with my tablet settings further last night and was wondering if there was an app that allowed you to monitor the GPU usage data. Everything I have found relates to CPU and battery data only and my searches for GPU monitoring are only bringing up PC solutions.
Thanks.
Have the h811 and using the app but don't know if it's working. On slumber mode
Which app are you referring too?
The deep sleep battery app? That's the first relevant thing I found in the playstore. And the comments on it don't seem too good.
A lot of folks here will recommend the greenify app instead and picking the apps you want to go into a sleep mode until triggered to wake up.

Yeah that's what I am referring to the deep sleep battery app, I as well am using greenify with xposed module for deeper sleep
With the screen off, you can just swipe down on the off screen to see the time. You will see that your mobile data is shut off. At least this works for me. I can clearly see my LTE symbol disappearing.

Have you been noticing difference with using deep sleep battery saver?

To be honest, I have. I also know that it's working because I swipe down when my screen is off and I see that my mobile data has shut off. Last night, I fell asleep without charging my phone at 67% and woke up to.... 67%, I was asleep for about 6 hours. I came from the Sony Xperia Z2 and kept stamina mode on 24/7. I was able to pull off well over 30 hours with that phone. Using deep sleep battery saver (which was based off the same idea as Stamina mode) I definitely noticed a difference in idle battery. Of course, once you get into any sort of task with the screen on then that's a different story.
The LG G4 already had pretty amazing idle times but I have a lot of apps that loves to wake up the phone when I'm sleeping. Before the app, I noticed that I'd wake up to maybe a 5% drain at minimum over the course of 6~7 hours. Sometimes, when my apps update on their own, I'd notice a significant drop of maybe even 10%.
I paid for the app since it's pretty cheap but honestly, I don't notice any real benefit to having the paid version. The paid version allows you to set some whitelist apps which is what Sony's Stamina mode allowed. However, if you're okay with not having that control then the free version is more than enough. Who knows, maybe some people will benefit less from it :/
I just want to make a point that I am also using it in conjunction with Greenify. I'm not sure if using the two really bears any great benefits but under my impression, greenify hibernates user apps while deep sleep can basically prevent anything from accessing data since it also shuts off mobile data. I can't see how using the two would hurt so why not? It looks like they both do different things that combined would be a very powerful battery saver.

I have Greenify as well and my battery life is TERRIBLE on this phone. I am lucky to get 8 hours before going from 100% to under 50%...I have a ton of bloat frozen and a ton of apps Greenified. What system apps are you Greenify'ing? The battery life is killing me on this phone, thank God I got a free battery with the promotion.

I didn't greenify any system apps. I just greenified every single user app that could potentially run while the phone was not in use. I also used tasker to force greenify my facebook app the minute the screen turns off instead of waiting for greenify to activate. I also used kernel adiutor to change the big core's governor to powersave and then changed the LITTLE core's governor to interactive.
Like I said in a previous post, I most use greenify for user apps as I kind of don't want to touch system apps at this moment. I use deep sleep battery saver for anything else that could potentially dodge greenify (like system apps that tries to access data). As all these settings so far are for when the screen is off, the Kernel Adiutor settings are for helping with battery life when the screen is on. I don't think the tasker setting is necessary as it very well could just be a placebo effect but I don't like how facebook isn't hibernated immediately.
So to sum it up; the settings I used:
Greenify all user apps
Use tasker to immediately greenify select apps that are power hungry
Use deep sleep battery saver
Use Kernel Adiutor and set big.LITTLE governors to powersave and interactive
**I should mention that I have the T-mobile H811 model which has an unlocked bootloader with a custom recovery.

Awesome, thanks for the informative reply. One question, wouldn't putting the CPU governor on powersave make the phone run really choppy/laggy? Also, I have the Verizon G4 no unlocked bootloader but root.

Most day to day tasks are done with the "LITTLE" cores while intensive tasks are done using the faster "big" so you won't normally notice any lag since the governor for the littles is interactive. I figured the only time I would really drain my battery is when I'm using intense tasks that would utilize the big cores. You will notice a little lag when in really heavy apps like the camera but it's really not that bad - it's not like a "I'm-going-to-miss-my-shot-because-it's-so-laggy" bad. Just give it a shot and you'll see what I mean. I don't use my phone for gaming but I do use it for almost everything else including streaming videos and I don't notice any lag other than in the camera - which, like I said, isn't that bad. If you do want to tweak around with the governor though, I high recommend Kernel Adiutor since it is compatible with the big.LITTLE system (meaning it can set the separate governor for both big and little cores) unlike Rom Toolbox Pro.
While I can bear with the slight lag for the extra battery life, you may not be able to take it. Your mileage may vary I guess. Battery life is much more important to me than high performance since I don't do anything intense like gaming or heavy rendering and I'm always on the go so I'm willing to make that sacrifice.
For me deep sleep has been giving me battery drain issues and uninstalled it after two days of use on slumber and my custom mode that didn't let no app awake and also the force tune cpu and what not yet still battery drain. With it off battery drains much much more less
