Let's face it -- Android phones use a lot of juice. They do a lot, and need a lot of power to do it, and the Evo 4G's big screen doesn't help matters. This makes a spare battery almost a must if you're on the go a lot. That's where the Seidio Innocell 1750 mAh battery comes in to the picture. While some folks prefer a much larger capacity battery, others (like myself) prefer something that uses the stock battery door, and fits into other accessories without any issue. An extra 250 milliampere-hours may not sound like a lot (the stock Evo battery is rated at 1500 mAh), but I've found it extends my usage by several hours. And I actually use my unlimited minutes, making several hours worth of calls daily.
Construction-wise, the Seidio Innocell 1750 is identical to the stock battery -- minus the color. My inner child would love to see it in red, but how often do we really see the battery? As you can see in the pictures (after the break) the Innocell is the same dimensions as the stock battery, and fits perfectly with the OEM battery cover. I know many of us carry a spare battery and swap mid-day, and the Innocell is perfect for this. It fits as you would expect, and offers a bit of extra oompf to make sure you're still up and running when you get to a charger.
If you use your Evo as intended, syncing mail and social networks, taking pictures, or playing games, you need to consider this one. You can grab the Seidio Innocell 1750 mAh battery from the Android Central store for $44.95. More pictures after the break.
