Hi All,
Well, I've had my SB for about 1.5 weeks and the battery experience has not been good. First, my SB arrived completed dead/battery drained. I had to plug it in to power up.
Then for 3 days of use, I was getting about 4-5 hours. After a few complete run down from 100% to around 2%-3%, recharge to 100%, the performance seem to have increased. I have been using it for work and getting about 8-9 hours. (I had set the SB to NEVER sleep on batter so I can test endurance.) I was thinking that perhaps a few full drain/recharge cycle was the cure for the poor battery life. Although, I'm not sure about the whole 12 hours of use per Panos.
Anyway, I had the SB fully charged to 100% yesterday and left it powered off/shut down. Well, less than 24 hours later, I turned it on an the battery was completely drained. This is ridiculous and very disappointing. I have a hard time believing Microsoft did experience this with the units before releasing. If they did, they knowingly released a bad product. (Class action anyone?)
I love the SB in every way but the battery problem is making me rethink the purchase. The amount of time that others have spent on returning, rebuilding, returning, rebuilding. etc. is not what a premium device experience should be. :-(
