Assuming JB is very polished, I will likely be holding on to my Bionic for some time longer:
After the first one they sent came up wanting, it seems Hyperion sent me a "good egg" Saturday because in the last 24-hrs, my Bionic has undergone both moderate and heavy use (with the screen on the brightest setting), and still hasn't drained the 4,000mAh battery down completely. However, both the built-in and GSam battery indicators have had it showing 1% for close to 10-hours now. I fully expected needing to charge it this morning, but that may have to wait until after lunch! I need to find a way to tweak this for accuracy. Still, I'm excited about the possibilities of going long periods of time without needing a charge!
On that note, does anyone know how to calibrate battery indicators for accurate readings? Will the Bionic or the GSam Battery app do this on its own? Or do non-OEM batteries prohibit accurate readings?
