[Tasker] Extreme battery saving profile

The battery life of an android phone is not impressive and we got used to charge our phones every day. Nevertheless it can happen that one finds himself in a situation with no charger in reach and no battery left. This profile will help you to avoid this situation. This profile will fire when your battery level will drop under 8% automatically. It is a drastic step, think twice before using it.
This task will:

• Put your phone into flight mode (I warned you, drastical steps ;)
• Set the display brightness to deep Darth Vader like darkness

Yes, you won't be reachable. But you can switch off the flight mode whenever you wish and still send or receive the important messages you would miss otherwise. In my opinion it's better then finding your phone completely drained without any options left. The phone should last minimum another hour in this mode.
You will need:

• Tasker
• Screen filter

This is what my profile looks like:

Profile: Extreme battery save (28)
     State: Battery Level [ From:0 To:8 ]
Enter: Extreme battery save (3)
     A1: Auto Brightness [ Set:Off ]
     A2: Display Brightness [ Level:0 Disable Safeguard:Off Ignore Current Level:Off Immediate Effect:On ]
     A3: Load App [ App:Screen Filter Data: Exclude From Recent Apps:Off ]
     A4: Airplane Mode [ Set:On ]
     A5: Notify LED [ Title:Battery low Text:Battery under %BATT percent!
          Will switch to battery saving mode. Icon:ipack:crystalhd:cache Number:%BATT Colour:Red Rate:1000 Priority:3 ]
     A6: Zoom Visibility [ Element:Extreme battery save.w / StateON Set:On ]

The normal mode profile could look like this and be activated when a power source is connected:

Profile: Power source connected (11)
     State: Power [ Source:Any ]
Enter: Energy save (17)
     B1: Notify Cancel [ Title:Battery low Warn Not Exist:Off ]
     B2: Airplane Mode [ Set:Off ]
     B3: Display Brightness [ Level:128 Disable Safeguard:Off Ignore Current Level:Off Immediate Effect:On ]
     B4: Auto Brightness [ Set:On ]
     B5: Zoom Visibility [ Element:Extreme battery save.w / StateON Set:Off ]
     B6: Run Shell [ Command:am force-stop com.haxor Timeout (Seconds):0 Use Root:On Store Output In: Store Errors In: Store Result In: ]

The line B6 kills the screen filter app if it is running and will do nothing if it's not running. To create it go to Script -> Run shell -> and enter the command am force-stop com.haxor :) The downside of this powerful command is, it needs root. Maybe you can get the same result by setting up the action App -> Kill App -> Screen filter. No guarantee on this.
You should have problems with creating lines A6 and B5 yet, as there is no Zoom widget yet. So... stay with me after the commercial break....

Off

Again there is a widget to switch this on and off from the home screen dynamically.
My widget looks like this, you will need two icon packs and the app Zoom to get the same result:

• Zoom
• Ipack / Crystal Project HD
• Ipack / Transparent Glass HD

More information on Zoom and how to setup cool widgets can be found on google and here.
Import my Zoom profile by saving the following file as "Extreme_battery_save.w.ztl.xml" under sdcard/Zoom/templates. Then open Zoom and press menu key -> Browse Templates -> Import Directory -> Extreme_battery_save.w.ztl.xml. Now create this Zoom 1x1 widget on your home screen.
