The Pandora has a 4.2Ah battery, which at a nominal 3.7V corresponds to 15Wh of energy.


Energy consumption is as follows:


  • the lid closed (screen off) and cpu idle: about 0.1W  (about 150 hours)
  • lid closed, playing music with Audacious: about 0.5W  (about 30 hours)
  • the lid open and screen on lowest non-zero brightness, cpu mostly idle: 0.65W  (I always use this brightness except outdoors)  --> this is roughly the power consumption of doing things like reading a PDF, coding or writing text. (about 23 hours)
  • screen at max brightness, cpu mostly idle: almost 1.2W (about 13 hours)
  • screen back at lowest non-zero brightness (brightness setting for all the next ones too, you can add the 0.55W yourself), artificial cpu stress test: 2W (about 7.5 hours)
  • NDS emulation with DraStic (new super mario bros, first levels) : about 1.6W (about 9 hours)
  • Playstation emulation with PCSX ReArmed at double resolution (FF7, battle scenes) : also about 1.6W
  • Playstation emulation with PCSX ReArmed at original resolution (FF7, battle scenes) : about 1.3W (about 11 hours)
  • SNES emulation with Snes9x4P (Super Mario World, first levels) : about 1.2W (about 12 hours)
  • Wifi on, screen on, downloading big files: about 1.8W (about 8 hours)
  • external (spinning) hard disk plugged in, copying a large file over to the SD card: 3 to 5W  (about 3 to 5 hours)
  • downloading a large file over wifi while copying a large file from an external hard disk while doing a cpu stress test with screen at max brightness: about 6W (about 2.5 hours)

I hope this helps to give you an accurate idea of the battery life of the Pandora. It's certainly much better than any smartphone or laptop.
