Good questions. I'm sure we will be getting more information on battery usage soon. I would not expect any damage to the LEDs, but can not guarantee.
I'm charging mine now...I'll kick off a battery drainage test around 2pm EST. FWIW, I've only had 5 or so recharges since purchace last saturday. I work from home, play on in constanly with screen brightness on "0" since day one, and I get about 8-9 hours of use. I just installed Quick Settings which allows me to turn down srceen brightness a few ticks lower than native "0"...its about the level of the "lock screen".
All that to say that I don't think my battery is at full potential.
