Picked mine up on Wednesday. yesterday I spent a lot of time playing and exploring, loading, etc. At 6.5 hours on the phone it was in the yellow zone. I started trying to do the HTC SYNC with my computer and it recharged so I don't have a good read right now. I did have an issue, I could not get my computer to recognize the phone so was not able to do the HTC SYNC. It kept saying, no device attached. Other than than, really a nice phone. Have a few days to play and am able to play with my daughters S3 and my grandson's (he went to the dark side) Iphone 5.
