Note: How to use Battery Doctor on Android 4.4 KitKat
Android 4.4_r1 removed the possibility for apps to request for the BATTERY_INFO permission, This is the commit https://android.googlesource.com/platform/frameworks/base/+/3714141d287c965ea3451831dd5167f63f8db87b%5E%21/
The reason (issue mentioned) for the commit is unknown.
This permission and the access to batterystats - formerly known as batteryinfo - service is vital for use cases (and apps) dealing with analysing awake and wakeup causes (battery drainers) as this services gives access to partial wakelocks and alarms.

I would like to request a rollback of the mentioned commit. See issue 61975

Here is a Solution from XDA forum by Xposed and download Version 5.1.0, Android 4.3 or older is well, you can flash older ROM

Hey man. I have some good feedback for you. After you made some changes to your app my battery life is longer. I see a huge improvement, my battery has now power to a whole day even if I play games and do some other stuff. Before that my battery was drained an hour before I went to bed. Now I have about 10-30% when I go to sleep AND now it's colder here in Denmark. Very cold. You know... batteries use more power when it's cold so that's a good thing, even if it's colder my battery lasts longer.

Heey all ,,after i test this app on my mothers xperia x10 (2.3.4 custom rom) and m fathers lg 2x speed (4.0.4 stock pre-rooted rom) this apps works really great up to 1,5 - 2 days
My battery problem is gone since i use this app

(i dont like battery saving apps because they draining my battery more than.before but this is really.amazing).
This app works only with root this tweaks the kernel ,wireless etc.. for each mode

I started in the evening, with fully charged battery, at 22.00. I checked battery status (%) next morning at 08.00

- without One Power Guard 2.2: 78%
- with One Power Guard 2.2: 97%

No need to say more... One Power Guard 2.2, at least for my phone, is working excellent!!!

Your scroll cache hack definitely
And maybe the One Power Guard app by onexuan, it is really really good. I don't know if it has anything to do with it, but since I installed it and set the CPU speed to min. 120MHz, max. 756MHz, the game lag with the oc kernel described in the Nameless thread lately is gone.
I'll ask einstein.frat about it btw, maybe it helps to have a flawless oc kernel by default.

I found the second solution, which is using the ONE POWER GUARD. Now, the battery life IMPROVES EVEN MORE! Now when I wake up to check my device, a whole night sleep is just draining 2-3% the most!

I found a difference only after using for 1 week..
Before using one power guard , battery was draining with 10% an hour during night(even when i dont use also) (So if at night its full charge at 6.00am it will be 40% charge left)
After using one power guard for one week , battery backup increased with more than 50%...(So at night if its full charge at 6.00am it was above 80% like that)

Install "One Power Guard" (https://play.google.com/store/apps/details?id=com.onexuan.battery&hl=en) and use the "AI" mode. It does not affect radio use, but rather optimizes the CPU governor in order to save power depending on what you are using this for. With bluetooth turned on for at least 6 hours a day, email, txting, web browsing and some video, my streak last me throughout the whole day, and I usually have about 20%-25% left by the time i get home at night--try it out!

Installing it now. I have been having horrible battery life recently. 2-3 hrs per battery with everything off (wifi, bluetooth, 3g, gps,etc...). I am currently looking at the battery usage screen. After 35m 31s, I have 59% battery left - (cell standby 39%,phone idle 31%, android system 17%, display 15%)
The screen is warm to the touch. I don't think that I could have 3 batteries go bad simultaneous? I haven't changed any settings recently. Im on the latest DSC 2.3. I did have a problem similar to this previously but it was a busybox upgrade that caused it. I downgraded and everything went back to normal.

I will let you know if "One Power Guard" solves my battery problem. Thanks

I have been using an app called One Power Guard which does seem to improve battery life mainly during standby without any discernible decrease in performance. This app causes various system and kernel tweaks,

Disabling data connections etc is well known to help improve battery life but I have also found a big difference by turing off Use Wireless networks in the Location and Security Settings.

A second battery with this ROM is recommended and I am very happy with the Mugen 1800mah battery.

For the battery drain issue, I used One Power Guard, which I tested before, it does reduce the power usage (Got a very good result during deep sleep, and daily usage... usually without using it, my battery drains at least 7% after whole night, while using it, my battery only drains about 3% the most!)

First option, I suggest you to use the ONE POWER GUARD app... The latest version is stable and there is a battery calibration function in the options.

Second option, download 'battery calibration' in the Google Play. Just for simple battery calibration only...

I STILL RECOMMEND ONE POWER GUARD. IT CAN OPTIMIZE YOUR KERNEL, ROM, WI-FI, 3G AND I/O SCHEDULER SO THAT TO MAINTAIN BATTERY LIFE. IT'S A NICE TRY.

Here is the step (The developer recommend us to follow these steps but not necessary)

THE FIRST AND SECOND STEP IS THE BATTERY CALIBRATION PROCESS

1. CHARGE your phone to 100%
2. Click on battery calibration button first (battery calibration app or ONE POWER GUARD app), then only plug off your charger.

Q：How to fix this app gets stuck at "Initializing"?
A：If this app gets stuck at "Initializing", please check this problem with SuperSU or Superuser not allowing it root access.

Q：Why the phone slow after I set?
A：I want to talk about my story, last night, a user looked for me, he said that his issue about installing the 2.1 version.he said his device lagged in the standby mode. I told that we work together to solve this problem. After work, I went back to my dorm. I started to write a test interface for him. 1.5 hours later, we started testing. He began to test my ten steps. Finally, each step ran well. But the issue had not yet been found. I let him try again AI mode.his device lagged.Because his device does not support to adjust the CPU. So my judgment is because IO schedule issue, he set the "CFQ", I let him try to change IO. (His Rom Only support CFQ and Noop). He changed to "Noop", All things became perfect. Finally solve the issue.

Final conclusion: Try to change some settings until it is the best.

Q：How to set?
A：The bloger write an article about One Power Guard, you can read it. http://pinoyflare.blogspot.com/2013/01/one-power-battery-guard-100-working.html

Q：Does this application modify the kernel? I am very worried about this.
A：Yes. This app modifies kernel parameters, Do not worry. For example: when you buy two different phones, whose kernel are not the same. Google Android also changes the kernel. Every producers are revising its own kernel.
If you are a geek, you can modify some of the initialization files and put them into init.d folder. Does this not modify the kernel?
When you root your phone, You have already modified your kernel.

If you are worried about this, you can uninstall this app and reboot your phone.

CPU Governors explained http://xdaforums.com/showthread.php?t=1369817

Q：Why display the maximum CPU Freq in the change mode interface?
A：This app get two file /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq and /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq value. If their value are max, will be displayed in UI.

Q：Why not support CPU frequency settings
A：This app get two file /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq and /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq value. If their are missing, will not support displayed.
You need to find a cause in your kernel

Q：Why do I recommend ondemand？
A：Because in my experience, it's the best. I test all Policy.If there is a better policy, please give me feedback.

Q：Why is there no “ondemand” “powersave” Option?
A：Because the kernel does not support.

What is a safe clean?
Android has a app process management mechanisms, when a process is killed by third-party applications, the android system will determine whether the process will be run again, if it is, the process will run, the kill process will repeat thereby creating an infinite loop, resulting in increased power consumption. Therefore, you should consider uninstalling third-party process management software.

Hi, Thank you for this application. Just installed will update the results later. Few questions for my understanding,

#1) I see different modes and from the name I can somewhat understand what it suppose to be. Is it advisable to have set it in one mode or different ones based on need. If so is it possible to do this automatically? ( Like on Night put it on Standby Mode, On Work hours Put it on Batter Saver, On Normal time put it on AI mode), As of now we need to do this manually, correct?
#2) Battery % is it possible to show them in increment of 1% rather than increment of 10%..I use Motrolo Atrix 2, it seems shows up only 80%, 90%...

Love the Circle and floating indicator of battery 1% make it even sweeter.

Thank you again.

1、Just use AI mode, you are able to enjoy all things.You do not always switch different modes.
2、For some strange reason, Motorola decided to only show the battery level in 10-percent increments on most of their Android devices.

Few suggestion

1.u can include info about each mode its not clear unless u r xda guy
2. Scheduler for mode would be great feature like in night i dont use phone much so i can put in power saver mode but do not want to do mannualy .we can automate mode switching according to time of day. Similar kind of mode switching automation will add 5 stars to your app

Great App. !! :thumbup:

Because the desktop has a floating window, when the calls comes in, this app needs to remove this floating window to ensure that does not affect the calls. Many APP to use this <uses-permission android:name="android.permission.READ_PHONE_STATE" />

i think you cannot change the behaviour of an application that wakeup too often.the problem is that the developper not well programmed his application . the only remedy is to replace by an alternative app more battery friendly(that wake up less)

Can you give me your phones CPU parameter? Files in this directory /sys/devices/system/cpu/cpu0/cpufreq
"the optimization tips notification is quite" Originally, you can turn off this tips in settings interface, but 1.9 version has a bug. I will fix turn off tips bug in 2.0 version.
