Word has been going around the forums since the beginning of an extended battery for the Shadow. Well the legend is true and I’m proud to present BoxWave’s ElectraSpan Extended Battery for the T-Mobile Shadow. While the OEM battery that comes with the Shadow has 920-1000mah of power, BoxWave’s comes packing 2200mah of juice for you to enjoy. Read on to find out the full scoop…

You do give up some slimness for the extra power. An extended battery cover comes with the battery that adds some extra bulk at the bottom back. This isn’t all bad as it allows you to stand the Shadow up on your desk for a neat parlor trick.

To show you how much of a difference the battery makes I ran a simple test on the BoxWave battery and the OEM battery that came with the Shadow.

For the test:

  • Streaming video over WiFi
  • Fullscreen video
  • Volume on high, played through speaker
  • Email set to check every 15 minutes

OEM Battery Results: On a full charge the OEM battery lasted through 1 hour 57 minutes of this brutality.

BoxWave ElectraSpan Extended Battery Results: From a full charge, BoxWave’s battery lasted 4 hours and 21 minutes. That’s almost 2.25 times longer than the OEM battery. Granted, most people don’t use their Shadow’s under these extreme conditions but this just gives you an idea of how much more time you will have with your Shadow. 2.25 times more between charges.

Right now BoxWave has a web special for this battery. Instead of $85.95 you can get it for $59.95. So if you want that extra go juice go to BoxWave’s page.

If it wasn’t for the bulk it would get 5, but instead I give it 4.5 Shadows!
