[Q] [ARC][Battery] Battery use shows 'Always Awake'

hey all,
Does anyone know why my Xperia Arc's Battery use says its always 'Awake'?
It seems to be chewing through my battery rather quickly recently. After 6 hours of very little use im down to 60% battery.
The only running processes are:
Settings (open to see battery use)
Facebook
3D Flip Clock
BatteryLife
DSP Manager
ROM Manager
Google Services
Android Keyboard
Ive heard there is an issue with the battery stats screen showing incorrect values for each process' drain percentage, my phone says Maps is using 70% and Cell standby only 10%.
Im trying right now with 3D Flip Clock not running to see if thats the issue.

[Q] App: OS Monitor - Power consumption?

I've been using an app called "OS MONITOR" https://market.android.com/details?id=com.eolwral.osmonitor&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5lb2x3cmFsLm9zbW9uaXRvciJd since I got my GN and I'm now on a mission to improve the battery life by seeing what programs I can disable/live without for the sake of battery life.
I've got the app running in the task bar and monitoring CPU usage with a refresh rate of 2 seconds.
Now from what I've noticed in battery settings, it doesnt seem to keep the phone awake and i still get 2+hours of screen time with fairly heavy usage.
Anyone familiar with the app and its power consumption?

Battery test,monitor, usefull apps for saving battery

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

[Help] Unsusal battery drain (keep awake, cpu usage)

Hey, about 2 weeks ago I noticed weird behavior from my battery.
When phone is locked battery drain is too fast.
It seems that the "android system" keep the phone awake for long periods,
And that the "android os" keep using the cpu.
I've been trying many thing - wifi, location, sync etc but nothing helped.
Used system panel to monitor my battery life,
Here are the results from the last 8 hours (100% at morning till now)
Attached photos - Overall battery usage, Screen on, Android System, Android OS, System Panel and More detailed system processes,
In the first 3 system processes there is high cpu usage even when screen is off..
(Top one, System, attached)
I know the overall battery using seems to be good,
But it's only because I've been using the phone the whole day.
The problem is when I'm not using it - it drain very fast with no reason.
I don't remember any change I've done (didn't update the software, maybe an app),
And before that the battery life was great (and so they are now if I'm using the phone continuously without "putting it in my pocket".)

Any help?

I have a brand new lg g3 d855 successfully updated to lollipop. The reason is still unknown i was having the same problem. But then in a video at youtube i saw an app known as "qualcommn snapdragon guru" download it use its feature to stop apps and all that stuff and battery will be very improved.

Well if i look at your screenshot i could say it was normal, the one that draining your battery is your screen (based on your ss). But in other way you can download some apps to control your kernel (e.g kernel auditor) and swipe to "kernel samepage merging" tab, look if its on or off, if on just turn it off and see your battery life then, it happen to me sometimes.

How to achieve 1 or 2% battery usage during mid night with LOS?

Let me put in the details.
I just came from MIUI 9.5.1x.y(forget the exact version) China version and now on LOS 15.1 official.
My old experience with that MIUI is optimal for standby battery life, especially during midnight with flight mode on. 8~9 hour just had the battery down by 1 ~2 percent at max. For MIUI, I use the built-in battery saving mode and disallowed most apps' background activities.
In LOS, I root and utilize greenify for similar task, and also enable the built-in battery saver. Yet, it gives me quite different result. About 7~8% usage overnight. That's far from optimal.
So my question are:
Do you have similar experiences?
If the answer is yes, how do you find the causes of the unnecessary battery drain? And how to solve it?
Any clues and helps are welcome.

Use an app to find out what is causing wakelocks during the night?
BetterBatteryStats for example.

You should Monitor Your Battery with Gsam and Betterbatterystatus Application also Monitor Cpu Deep Sleep

got to battery stat in system setting , check what apps running in background and disable(if available) what apps that can running in background.
