Create a beautiful design for an android battery saving app

Rocket is a battery saving app. You can create multiple battery saving modes that will reduce screen brightness, turn off wifi, stop power consuming apps, etc. The modes can also be scheduled to occur at a specific time of day, or battery % threshold, etc.

The design should be android-like but it should have a playful fun feel to it

Rocket

1. The list screen (main screen)
- Shows the current battery level %
- Shows the time remaining till the battery level is empty (if unplugged) or it shows the time remaining till the battery level is full (if plugged)
- Shows a list of battery modes. One undeletable 'normal' mode that allows users to setup their everyday battery optimization settings. The list also shows other custom(deletable) user created battery modes. It also allows for the ability to apply the mode by tapping on it, and the ability to edit a mode with the arrow. 

2. The edit screen (to create or edit battery modes)
- Each mode has a name, multiple schedules and multiple settings. The schedules and settings can be added or removed.

Schedules are:
- Screen Lock : When the screen is turned off, it will apply the settings
- Battery Level limit: When the battery drops below a certain %. Option to pick the % level.
- Time: A time range (start and endtime) that can be set to repeat for any day of the week

Settings are:
- Wifi (on/off)
- Bluetooth (on/off)
- Screen timeout (one of: 15secs, 30secs, 1min, 2mins, 10mins, 30mins)
- Brightness (0 - 100%, with an option to set the brightness to 'automatic')
- Stop power consuming apps - Stops background apps
