The DIY maniacs at iFixit got their hands on the new Kindle Fire HD, cracked it open and found out some neat new details about the beautiful new 7-inch tablet's guts.
Until now, we knew Amazon's spec battery life for the awesome the Kindle Fire HD, but we didn't actually know how big the battery was. Turns out the Kindle Fire HD has 4400 mAh, 16.43 Wh Li-ion battery compared to a 4326 mAh, 16 Wh battery on the Nexus 7. They're supposed to last 11 hour and 9.5 hours respectively. How does that tiny difference in battery size account for the difference in battery life? Good chance it has to do with the processors at work in each tablet.
