I had the 1750mAh Seidio battery in my Inc 2 for a few days, but started getting some random reboots. While it was in, I noticed a little improvement in battery life, but I hadn't used the phone a lot since I switched to it. I have no idea if the random reboots are actually from the battery though, but I took it out and put the original battery in just to see. It seems like no one can quite figure out why they're getting random reboots.
