I'm not looking for suggestions that mention carrying power banks or charging strategies, as this is for in times when I won't be able to use them. Don't worry; this is a hypothetical question and I'm not in any problem.I want to be able to maximize the phone's potential as an offline, portable computer.What I already know:
- Using airplane mode to prevent antennas from drawing power.
- Keeping screen off as much as possible.
- Removing any and all memory consuming widgets and live wallpapers.
- Use a pitch black wallpaper. Useful at least on an OLED display.
