I mostly keep it simple...
So now I'll try to make is as simple as possible...
Lets start with
Settings:
1. Scanning always available for WiFi and Bluetooth: Turned Off (Location->Top Right->Scanning->Turn both off)
2. Theme: Dark (I like it, and its good for OLED displays)
3. Font size: Small (More text in same window)
4. Display size: Small (Same reason)
5. Scheduled power on/off: Enabled (So that the device gets its usual refresh on daily basis)
Extra: Reduce Animation Scale under developer options (Can make it look like the phone is fast)
Others would be:
1. Using dark wallpapers (because OLED and I love dark wallpapers)
2. Using Substratum (To get Pitch black theme and Red accent color mainly)
3. Using Launchers like Nova Prime (Coz tones of customization)
For
Wallpapers, I like any wallpaper app with tones of dark wallpapers, and then using app like Smart Wallpaper to enable auto-switching of these beautiful wallpapers...
Substratum, Well... I use it to get better looking apps and pitch black theme with red accent color... So I'm using Pitch Black Theme...
Nova Prime, Well I have 3 home pages, Main screen containing Pixel 1 kind of search bar on top, Analog clock in the center and Google Fit steps counter in the bottom.
Second screen is weather widget, Calendar events, Media widgets and apps in the bottom.
And last screen is just games apps icons.
Now nova settings time:
1. Desktop/App Drawer Grid size: 6x5 (As it doesn't look that clumsy and confusing and at the same time, the spacing between the icons remain optimum in this grid)
2. Dock contains 7 icons (Only the Important Icons like Phone, messaging app, Instagram, Chrome, Camera, Community and WhatsApp)
3. For Dock I'm using Whicons Icon pack (As the wallpaper is kinda black, white icons looks cool on them)
4. For Desktop/App Drawer, I'm using a mix of Built-in, Circlet, DmonD, Flix, Polycon, Talitha Square Icon packs
So this is how I keep it clean and simple...
