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:

Jelly-Bean 4+ or KitKat ROM 4.4+

Samsung Galaxy S4 ( don't matter wich version) or any other Android Device

root ( custom rom is not nessesery but will make some things easier, i prefer Mahdi with KT-Kernel)

Tasker ( Play Store " 2,99$ ")

Lux ( Play Store " 3,80$" )

Hold Screen on ( Play Store )

Greenify root

Securesettings ( Play Store " free" )

F-Droid ( alternativ store "free") DOWNLOAD LINK

Hal Monitor ( F-Droid Store "free" )

Wifi-Matic ( F-Droid Store "free" )

Automatic 2G Toggle for non CM /AOSP/.. ROM ( e.g. Touchwiz, Xperia, Google,...) LINK XDA
