Easy Guide to save battery on EVERY Android Device with ANY ROM

[neunzehn77]

Guide for AOSP / CM / AOKP / Original TW-based Roms, every Stock-ROM with root, nearly every Custom Rom ​

Works on:

• Samsung Galaxy S4
• Samsung Galaxy S3
• Samsung Galaxy S2
• Samsung Galaxy Note
• LG 2
• Sony Xperia
• HTC One
• nearly every other Android based Device incl Tablet`s with Android Jelly-Bean or KitKat

One of the most annoying things is the battery consumption of our devices.There are so many Apps in Play Store but most of them are " a Fairy tale"..
There are different ways to save battery. you could under volt your cpu, disable mobile date.. disable synch ect pp...Since 2010 i play around with different Android devices and here is an easy way to save battery. My way will automatic change to the best settings WITHOUT any undervolting, CPU-Tweaks and you will always be able to send and receive data.. I tried different setups, while normal use.

My definition of normal use:

Samsung Galaxy S4

30h of Power ( Mahdi 01/11 KitKat Rom ART active, KT-Kernel without any tweak)

• GPS-Navigation with Google Maps for 42Min
• Calls about 58:35 Min
• Whatsapp online (all the time)
• FB Messanger Push on
• FB
• Kaiten Mail push active (wrote some Mails)
• 13 SMS sent
• Audiobook via PowerAmp 120 min
• Screen on for 5h
• Location-Sevice and Data always on

76h of Power ( Mahdi 01/06 KitKat Rom ART active, KT-Kernel without any tweak)

• nearly the same use
• with "automatic Airplane-Mode from 22:30h - 9h

If you follow the steps your phone will:

• Switch GPS on if you need it and turn it off
• turns HSDPA+ / LTE on when you are not connected to an WIFI-Network and you turn the screen on
• Switch HSDPA+ / LTE to 2G when your Screen is off
• turn the screen off when you are not looking at the screen
• turn the Screen off when you close the S-Cover ( Samsung Galaxy S4 on EVERY ROM)
• turn WIFI on if you nearby a known WLAN-Station and off when you are leaving the location ( no matter how many "known" networks with automatic localization " Cell")
• switch to 2G and turn of mobile Date if you connected to any WLAN
• close apps when screen turns off ( FB or any other app.. its up to you)

before we start you need:

1. Jelly-Bean 4+ or KitKat ROM 4.4+
2. Samsung Galaxy S4 ( don't matter wich version) or any other Android Device
3. root ( custom rom is not nessesery but will make some things easier, i prefer Mahdi with KT-Kernel)
4. Tasker ( Play Store " 2,99$ ")
5. Lux ( Play Store " 3,80$" )
6. Hold Screen on ( Play Store )
7. Greenify root
8. Securesettings ( Play Store " free" )
9. F-Droid ( alternativ store "free") DOWNLOAD LINK
10. Hal Monitor ( F-Droid Store "free" )
11. Wifi-Matic ( F-Droid Store "free" )
12. Automatic 2G Toggle for non CM /AOSP/.. ROM ( e.g. Touchwiz, Xperia, Google,...) LINK XDA

If you root your S4 and install Security Settings and install the "Helper" you will be able to switch between 3g/ 2g.. via Tasker...If you want i will make a little guide with screenshoots..

Guide for TW-based Custom-Roms ( Echo-Rom,...)​

First of all is: You need a custom rom TW-based e.g. Echo, Omega, ( be sure to use the right modem to solve 4.3 TW-Based Rom`s failure of losing data-conection while screen is off)

1) go to Google Play Store and instal Tasker
2) go to Google Play Store and instal Secure Settings (Pic 1)
3) launch Secure Settings and instal Helper 1.2.3 ( Pic 2)
4) Open Tasker and create a new task e.g. "2G off" choose plugin " Secure Settings" ( Pic 3)
5) Scroll down to " LTE" and mark " toggle" and save ( Pic 4)
6) Save Task and make a second Task with the name e.g. " 2G on" with exact the same settings
7) Use my Tasker Settings and change Task form " HSDPA off" to your Task 2G off and "HSDPA on" to your Task "2G on"

Have fun.... cheers


Pic 1) Secure Settings

Pic 2) Helper Screen

Pic 3) Choose Plugin " Secure Settings"

Pic 4) Mark "toggle"

 

[kenn7]

7) Use my Tasker Settings and change Task form " HSDPA off" to your Task 2G off and "HSDPA on" to your Task "2G on"

i believe u got it the other way around, hdspa off --> 2G on and hdspa on --> 2G off

one question though, if i still choose to use ur task, can i use it instead of changing it?

i'm using a TW-based custom rom

thx

It would be nice if you will do a video tutorial to it,
even without voice commentary.

Because I do not understand the point with tasker plugins.

But so with a TW ROM is it not possible to switch 3G to 2G and vice versa? Is it only possible to deactivate data traffic?

I hope i understand your post correct...

The difference between CM / AOSP / AOKP and TW custom rom is, that you are able to choose directly 2G on/off ..for example:

On CM / AOSP /... you could use Tasker to switch directly without any tool ( e.g.Secure Setting ) between the different network-modes. take a look on picture 1- 3

On TW-based custom rom, you`ve only the choice to " toggle" ( with tools like Secure Setting) the network-modes. This means that you coulden`t define exactly the network-mode! You are only able to toggle the mode for example :
You are on 2G/WDMC/LTE the next "modus is "2G"... so if the task starts it will toggle from 2G to 2G/WDMC/LTE... if the SAME task runs again it will toggle from 2G/ WDMC/LTE to 2G...

You could use my " Taker settings" from first post but you have to change the task "HSDPA on" and "HSDPA off" to "toggle" like I explained it on post 13...

cheers

CM / AOSP / AOKP direct Settings to define network-mode​

Sorry mate.. english is not my nature language.. and my school english is about 20 years ago... so it makes no sense .. but alternativ i could make a screencast but ONLY on KitKat CM / AOSP / ... please take a look at the tutorials about tasker how to create new tasks... SORRY

Yes and No... you could toggle the network-mode ( root + custom TW-Rom like echo-rom, omega-rom,... + Secure Settings)
Please take a look at post #18
