[Galaxy 3 General] neo1691:
Hello everyone.

I used to be very disappointed on the battery performance of our stock roms. Our customs roms solved many problems but this battery problem stayed for some people like me.! So i started experimenting on various categories and now i finally have a sufficient battery backup of around 40 hours that keeps me and my android going!! :D

So here is how to save your damn precious battery!!

It has worked for some people i know and i hope it do work for you too!!

I am using fugumod ultra kernal and it gives me absolutely no lags at all + a super duper battery!!

-

Battery Calibration

[ROOT]

Whenever you flash any new custom rom, you should always calibrate your battery! Here is an app that does that!!

-

Flash Fugumod ultra kernel

(Strictly for Fugumod Ultra) )<link>

Flash this kernel and use set

minimum frequency

for 780 hz and

Maximum frequency

to 1366 hz.

Set the governor to Performance

:eek::eek: CONFUSED Yes this thing sounds crazy!! But you can always try. I have written this after experiencing it myself!! :D

-

For G3Mod Kernels & Other Versions Of fugumod [OverClocked]

Follow these steps:

Install Setcpu/ Any other cpu controll app

Set Max value to the highest frequency. Minimum between 300-400.

Now using the profiles option set POWERSAVE governor to those times when you wont be using your phone much (ex:while sleeping).

Then for other times use ONDEMAND governor.

While charging profile is set then make sure that governor is set as PERFORMANCE.

You may also try other governors. Haven't tried... (suggestions welcome)

-

Install Auto Memory Manager app

[ROOT]

Auto memory app automatically kills apps that runs in background based on the profile u set!! After installing the app, use the aggressive profile and the lower the

Hidden Application

slider to in between 30-40 mb, so that your important background apps are not killed unless the ram is very low..!!

----------------Alternative For Auto Memory Manager-------------------------

-

Supercharger script

Supercharger script is also a great alternative.. You need to run the script from your rooted rom using terminal emulator. See this <link>

This script is included in most of the recent custom roms. See their respective version changelog for info.

Now your phone will be lag free..!! It has been tested and working!! My android phone runs the way it should!!

Lets jump to battery problems

-Battery Calibration has to be done.!!

-After that I recommend you to use your resources a bit cleverly!! Data connection takes a lot of battery for me.! Now fine you need internet when you are on the move. But you don't need it while sleeping do you?? :eek:

android apps requiring data connection to retrieve data keep on retrieving it even while you sleep but you only see that data after waking up and getting out of our bed. So you should shut off internet while sleeping!!

-Now display.

display consumes battery!! best is to keep display to 10 when its dark!! And around 40 during the day!

I keep it to zero all the time and use keep toggling it to max only when i need it using dimmer!!

-3d Gallery. (thanks rai_tushar)

Consumes a lot of battery!! Use quickpic. Better and faster alternative

More tips by rudolf895

*Not using set CPU for short time profiles.(not using different frequency while phone is on standby)

*Exiting apps using the back key, home key put the apps to background task.

*using 2g when needed..

*use wifi for bigger than 10mb download as it woudl be fast n easy.

*least brightness

So i think that should be it.!!

One last trick.

If you use tasker or any other automation app try this.

(With respect to tasker)

Make a new context>state>plugged in

Then make a new task for the context>app>load app>Fast reboot <link>

So whenever you will plug in your phone the app be will run automatically and then your phone will be free from any lags.

Data Connection uses lots of battery and will result in battery drain. Most of the time many data is retrieved when you wont be viewing it/using it. But it will result in wastage of data. So u need to make sure you use your data connection wisely :D

i would highly recommend you all to use tasker app for automation of your android phone. Automatically toggle display, mobile data etc depending upon various contexts (application, time, location). Read THIS thread for more information on tasker.

Conclusion

If you want a rock solid battery and an android phone that should be proud of its speed, and you are not getting any solution, go ahead and try the above..!!

Battery setting may or may not suit you!! This was just a sharing of my experiences which i had en-route to getting a lag-free/rock-battery.

Happy Androiding!! :D
