I thought it would be quite interesting to get an idea about how long the 350 & 650 hold their charge. I'm going to start keeping track, see if I can find a bench-mark, but has anyone already tried ?
I'd especially like to know how long they'll sit in sleep mode without a top-up.
Obviously, the time will vary enormously in use, depending how much time is spent reading, turning pages, etc....
It might also give an indication as to whether battery performance is improved or diminished by different charging regimes. I follow the "never power down, charge as soon as it's on 2 bars, and leave to charge overnight " way, which seems to be best practice, and I've noticed the 650 holds it's charge better now than earlier.
Perhaps the battery has just been bullied into pulling it's socks up......
